But it will eventually work as stanard clang does honoring your standard permutations of `-emit-llvm`, `-S`, `-c`, `-emit-llvm-only` etc. --- clang/include/clang/Basic/LangOptions.h | 3 - clang/include/clang/CIR/CIRBuilder.h | 18 +- .../clang/CIRFrontendAction/CIRGenAction.h | 90 ++++++++++ clang/include/clang/Driver/Options.td | 30 ++-- .../include/clang/Frontend/FrontendOptions.h | 26 +-- clang/lib/CIR/CIRBuilder.cpp | 41 +++-- clang/lib/CIR/CMakeLists.txt | 1 - clang/lib/CIR/FrontendAction/CMakeLists.txt | 7 + clang/lib/CIRFrontendAction/CIRGenAction.cpp | 162 ++++++++++++++++++ clang/lib/CIRFrontendAction/CMakeLists.txt | 32 ++++ clang/lib/CMakeLists.txt | 1 + clang/lib/Driver/ToolChains/Clang.cpp | 22 --- clang/lib/Frontend/CompilerInvocation.cpp | 7 +- clang/lib/FrontendTool/CMakeLists.txt | 1 + .../ExecuteCompilerInvocation.cpp | 17 ++ clang/lib/Sema/CIRBasedWarnings.cpp | 3 +- clang/test/CIR/CodeGen/basic.c | 3 +- clang/test/CIR/CodeGen/types.c | 5 +- llvm/docs/CIR.rst | 15 +- 19 files changed, 403 insertions(+), 81 deletions(-) create mode 100644 clang/include/clang/CIRFrontendAction/CIRGenAction.h create mode 100644 clang/lib/CIR/FrontendAction/CMakeLists.txt create mode 100644 clang/lib/CIRFrontendAction/CIRGenAction.cpp create mode 100644 clang/lib/CIRFrontendAction/CMakeLists.txt diff --git a/clang/include/clang/Basic/LangOptions.h b/clang/include/clang/Basic/LangOptions.h index 485b58632003..949c8f5d448b 100644 --- a/clang/include/clang/Basic/LangOptions.h +++ b/clang/include/clang/Basic/LangOptions.h @@ -576,9 +576,6 @@ class LangOptions : public LangOptionsBase { /// host code generation. std::string OMPHostIRFile; - /// Name of the CIR file to output to disk. - std::string CIRFile; - /// The user provided compilation unit ID, if non-empty.

For the time being we only really care about two valid types -- Direct (for simple args such as ints) and Ignore (void). The rest of the class is to provide the opportunity to assert at places where clang has differing behavior. e.g. if clang's codegen does `if (isInAlloca) doSomething();` we want to be able to assert that we aren't seeing an `isInAlloca` so that we don't forget to handle that situation later. This logic is pervasive through many of the following diffs. Most of the code is redundant and lifted from clang solely so we don't end up with things going down codepaths we don't anticipate and that we can enforce it with liberal usages of asserts. There is also the question of whether or not we need ABIArgInfo at the moment or anything ABI related at all. We could reason that we should prefer minimizing ABI interference in the highest levels of CIR. The hardest part of CIR is going to be getting it correct and working at all. Minimizing the divergences from clang seems like the easiest way to do this. If/when we get to the question of making it faster to compile and better at optimizing code we can focus on luxury things like lowering ABI decisions to mid-level CIR. --- clang/lib/CIR/CIRGenFunctionInfo.h | 180 +++++++++++++++++++++++++++++ 1 file changed, 180 insertions(+) create mode 100644 clang/lib/CIR/CIRGenFunctionInfo.h diff --git a/clang/lib/CIR/CIRGenFunctionInfo.h b/clang/lib/CIR/CIRGenFunctionInfo.h new file mode 100644 index 000000000000..25b12df156c8 --- /dev/null +++ b/clang/lib/CIR/CIRGenFunctionInfo.h @@ -0,0 +1,180 @@ +//==-- CIRGenFunctionInfo.h - Representation of fn argument/return types ---==// +// +// Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. +// See https://llvm.org/LICENSE.txt for license information. +// SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception +// +//===----------------------------------------------------------------------===// +// +// Defines CIRGenFunctionInfo and associated types used in representing the +// CIR source types and ABI-coerced types for function arguments and +// return values. +// +//===----------------------------------------------------------------------===// + +#ifndef LLVM_CLANG_CIR_CIRGENFUNCTIONINFO_H +#define LLVM_CLANG_CIR_CIRGENFUNCTIONINFO_H + +#include "clang/AST/CanonicalType.h" + +#include "llvm/ADT/FoldingSet.h" +#include "llvm/Support/TrailingObjects.h" + +#include "mlir/Dialect/CIR/IR/CIRTypes.h" + +namespace cir { + +/// ABIArgInfo - Helper class to encapsulate information about how a specific C +/// type should be passed to or returned from a function. +class ABIArgInfo { +public: + enum Kind : uint8_t { + /// Direct - Pass the argument directly using the normal converted CIR type, + /// or by coercing to another specified type stored in 'CoerceToType').

- Implement the core logic from Herb's wg21.link/p1179, for now only implement basic tracking, no multi-level ownership just yet. - In the example below it's capable of diagnosing a bad uses of "p": ``` void basic() { int *p = nullptr; { int x = 0; p = &x; *p = 42; } // x dies in the end of scope *p = 42; // emit a warning on the bad use of 'p' } ``` There's a lot to be done still, but this paves the road for supporting more C++ along side with more accurate tests. --- clang/test/CIR/Transforms/lifetime-check.cpp | 9 +- .../Dialect/CIR/Transforms/LifetimeCheck.cpp | 323 +++++++++++++++++- 2

Every region now has a cleanup block, that ends up being merged back to the entry block in most cases. Lowering to LLVM will requiring chaining all these cleanup blocks. - Create an alloca to hold the return. - Always generate a branch instruction and a return block. - Clean that up as part of the MergeCleanups pass. - Update tons of tests. - Fix some of the verifiers scope/if (needed for early returns). - Enable MergeCleanupsPass, which is needed by this test rewrites. --- clang/lib/CIR/CIRGenFunction.h | 11 +- clang/lib/CIR/CIRGenModule.cpp | 300 ++++++++++++------- clang/lib/CIR/CIRGenModule.h | 68 ++++- clang/lib/CIRFrontendAction/CIRGenAction.cpp | 2 +- clang/test/CIR/CodeGen/basic.c | 34 ++- clang/test/CIR/CodeGen/basic.cpp | 102 +++---- clang/test/CIR/CodeGen/goto.cpp | 38 ++- clang/test/CIR/CodeGen/sourcelocation.cpp | 90 +++--- clang/test/CIR/IR/invalid.cir | 2 +- mlir/include/mlir/Dialect/CIR/IR/CIROps.td | 27 +- mlir/lib/Dialect/CIR/IR/CIRDialect.cpp | 185 ++++++------ 11 files changed, 492 insertions(+), 367 deletions(-) diff --git a/clang/lib/CIR/CIRGenFunction.h b/clang/lib/CIR/CIRGenFunction.h index ddc96041d277..4e212ce0da6a 100644 --- a/clang/lib/CIR/CIRGenFunction.h +++ b/clang/lib/CIR/CIRGenFunction.h @@ -17,6 +17,7 @@ #include "CIRGenModule.h" #include "CIRGenValue.h" +#include "mlir/IR/TypeRange.h" #include "mlir/IR/Value.h" #include "clang/AST/DeclObjC.h" #include "clang/AST/ExprCXX.h" @@ -51,15 +52,9 @@ class CIRGenFunction { ForceRightToLeft }; - /// If a return statement is being visited, this holds the return statment's - /// result expression. - const clang::Expr *RetExpr = nullptr; - - mlir::Value RetValue = nullptr; - std::optional RetLoc; - - mlir::Type FnRetTy; clang::QualType FnRetQualTy; + std::optional FnRetTy; + std::optional FnRetAlloca; CIRGenModule &CGM; diff --git a/clang/lib/CIR/CIRGenModule.cpp b/clang/lib/CIR/CIRGenModule.cpp index c61a8f96ec6b..ae3bad12b495 100644 --- a/clang/lib/CIR/CIRGenModule.cpp +++ b/clang/lib/CIR/CIRGenModule.cpp @@ -86,10 +86,10 @@ CIRGenModule::CIRGenModule(mlir::MLIRContext &context, clang::ASTContext &astctx, const clang::CodeGenOptions &CGO) : builder(&context), astCtx(astctx), langOpts(astctx.getLangOpts()), - codeGenOpts(CGO), theModule{mlir::ModuleOp::create( - builder.getUnknownLoc())}, - target(astCtx.getTargetInfo()), - ABI(createCXXABI(*this)), genTypes{*this} {} + codeGenOpts(CGO), + theModule{mlir::ModuleOp::create(builder.getUnknownLoc())}, + target(astCtx.getTargetInfo()), ABI(createCXXABI(*this)), + genTypes{*this} {} CIRGenModule::~CIRGenModule() {} @@ -115,6 +115,36 @@ mlir::Location CIRGenModule::getLoc(mlir::Location lhs, mlir::Location rhs) { return mlir::FusedLoc::get(locs, metadata, builder.getContext()); } +// Allocas are expected to be in the beginning of the entry block +// in whatever region they show up. +static void updateAllocaInEntryBlock(AllocaOp localVarAddr) { + auto *parentBlock = localVarAddr->getBlock(); + auto lastAlloca = std::find_if_not( + parentBlock->begin(), parentBlock->end(), + [](mlir::Operation &op) { return isa(&op); }); + if (lastAlloca != std::end(*parentBlock)) + localVarAddr->moveBefore(&*lastAlloca); + else + localVarAddr->moveBefore(&parentBlock->front()); +} + +void CIRGenModule::buildAndUpdateRetAlloca(QualType T, mlir::Location loc, + CharUnits alignment) { + auto localVarTy = getCIRType(T); + auto localVarPtrTy = + mlir::cir::PointerType::get(builder.getContext(), localVarTy); + + auto alignIntAttr = + mlir::IntegerAttr::get(mlir::IntegerType::get(builder.getContext(), 64), + alignment.getQuantity()); + auto addr = builder.create( + loc, /*addr type*/ localVarPtrTy, + /*var type*/ localVarTy, "__retval", InitStyle::uninitialized, + alignIntAttr); + updateAllocaInEntryBlock(addr); + CurCGF->FnRetAlloca = addr; +} + mlir::LogicalResult CIRGenModule::declare(const Decl *var, QualType T, mlir::Location loc, CharUnits alignment, @@ -137,17 +167,7 @@ mlir::LogicalResult CIRGenModule::declare(const Decl *var, QualType T, loc, /*addr type*/ localVarPtrTy, /*var type*/ localVarTy, namedVar->getName(), IsParam ?

Lanza Date: Fri, 11 Oct 2024 12:09:40 -0700 Subject: [PATCH 0257/2301] [CIR][NFC] Refactor CIRGenModule's member fns to CIRGenFunction Also, distribute the new CIRGenFunction member fns to their corresponding locations that match CodeGen. e.g. CG{Decl,Stmt,Expr}. Still to be done: * order the functions both more logically as well as more alike how codegen's functions are ordered. * clean up access specifiers. I didn't do a great job tracking where things should go as far as access. --- clang/CMakeLists.txt | 2 - .../clang/CIR/Dialect/IR/CMakeLists.txt | 0 clang/lib/CIR/CIRGenCall.cpp | 84 + clang/lib/CIR/CIRGenCleanup.cpp | 46 + clang/lib/CIR/CIRGenDecl.cpp | 368 ++++ clang/lib/CIR/CIRGenExpr.cpp | 492 ++++- clang/lib/CIR/CIRGenExprScalar.cpp | 108 +- clang/lib/CIR/CIRGenFunction.cpp | 445 ++-- clang/lib/CIR/CIRGenFunction.h | 422 +++- clang/lib/CIR/CIRGenModule.cpp | 1927 +---------------- clang/lib/CIR/CIRGenModule.h | 400 +--- clang/lib/CIR/CIRGenStmt.cpp | 878 ++++++++ clang/lib/CIR/CIRGenerator.cpp | 4 +- clang/lib/CIR/CMakeLists.txt | 19 +- clang/lib/Sema/CIRBasedWarnings.cpp | 2 +- clang/test/CIR/global-var-simple.cpp | 60 + clang/test/CIR/hello.c | 5 + 17 files changed, 2710 insertions(+), 2552 deletions(-) create mode 100644 clang/include/clang/CIR/Dialect/IR/CMakeLists.txt create mode 100644 clang/lib/CIR/CIRGenCleanup.cpp create mode 100644 clang/lib/CIR/CIRGenDecl.cpp create mode 100644 clang/lib/CIR/CIRGenStmt.cpp create mode 100644 clang/test/CIR/global-var-simple.cpp create mode 100644 clang/test/CIR/hello.c diff --git a/clang/CMakeLists.txt b/clang/CMakeLists.txt index d0a828029561..b79e570667b2 100644 --- a/clang/CMakeLists.txt +++ b/clang/CMakeLists.txt @@ -166,8 +166,6 @@ if(CLANG_ENABLE_LIBXML2) endif() endif() -set(CLANG_ENABLE_CIR FALSE) - if(CLANG_ENABLE_CIR) if (CLANG_BUILT_STANDALONE) message(FATAL_ERROR diff --git a/clang/include/clang/CIR/Dialect/IR/CMakeLists.txt b/clang/include/clang/CIR/Dialect/IR/CMakeLists.txt new file mode 100644 index 000000000000..e69de29bb2d1 diff --git a/clang/lib/CIR/CIRGenCall.cpp b/clang/lib/CIR/CIRGenCall.cpp index 501fac42d52e..9a290f69cd3c 100644 --- a/clang/lib/CIR/CIRGenCall.cpp +++ b/clang/lib/CIR/CIRGenCall.cpp @@ -159,6 +159,14 @@ void ClangToCIRArgMapping::construct(const ASTContext &Context, } // namespace +static bool hasInAllocaArgs(CIRGenModule &CGM, CallingConv ExplicitCC, + ArrayRef ArgTypes) { + assert(ExplicitCC != CC_Swift && ExplicitCC != CC_SwiftAsync && "Swift NYI"); + assert(!CGM.getTarget().getCXXABI().isMicrosoft() && "MSABI NYI"); + + return false; +} + mlir::FunctionType CIRGenTypes::GetFunctionType(clang::GlobalDecl GD) { const CIRGenFunctionInfo &FI = arrangeGlobalDeclaration(GD); return GetFunctionType(FI); @@ -490,3 +498,79 @@ RValue CIRGenFunction::buildAnyExprToTemp(const Expr *E) { assert(!hasAggregateEvaluationKind(E->getType()) && "aggregate args NYI"); return buildAnyExpr(E, AggSlot); } + +void CIRGenFunction::buildCallArgs( + CallArgList &Args, PrototypeWrapper Prototype, + llvm::iterator_range ArgRange, + AbstractCallee AC, unsigned ParamsToSkip, EvaluationOrder Order) { + + llvm::SmallVector ArgTypes; + + assert((ParamsToSkip == 0 || Prototype.P) && + "Can't skip parameters if type info is not provided"); + + // This variable only captures *explicitly* written conventions, not those + // applied by default via command line flags or target defaults, such as + // thiscall, appcs, stdcall via -mrtd, etc. Computing that correctly would + // require knowing if this is a C++ instance method or being able to see + // unprotyped FunctionTypes. + CallingConv ExplicitCC = CC_C; + + // First, if a prototype was provided, use those argument types. + bool IsVariadic = false; + if (Prototype.P) { + const auto *MD = Prototype.P.dyn_cast(); + assert(!MD && "ObjCMethodDecl NYI"); + + const auto *FPT = Prototype.P.get(); + IsVariadic = FPT->isVariadic(); + assert(!IsVariadic && "Variadic functions NYI"); + ExplicitCC = FPT->getExtInfo().getCC(); + ArgTypes.assign(FPT->param_type_begin() + ParamsToSkip, + FPT->param_type_end()); + } + + // If we still have any arguments, emit them using the type of the argument. + for (auto *A : llvm::drop_begin(ArgRange, ArgTypes.size())) { + assert(!IsVariadic && "Variadic functions NYI"); + ArgTypes.push_back(A->getType()); + }; + assert((int)ArgTypes.size() == (ArgRange.end() - ArgRange.begin())); + + // We must evaluate arguments from right to left in the MS C++ ABI, because + // arguments are destroyed left to right in the callee.

This change was initially done because yielding a value out with loopcondition require adding arguments to all regions involved, and the approach was somewhat brittle.

changes to CIRGenerator, CIRGenFunction and CIRGenModule break this functionality. We'll have to figure out how to rewrire this. We're going to need to have a system where the CIRBasedWarnings owns the full CIRGen pipeline. We're currently just asking CIRGenerator to ask CIRGenModule to build a function, but given that CGM has state that is required to exist for CIRGenFunction (which has it's own state) this no longer makes sense.

A simple example is linkage. We haven't defined anything to do with linkage yet. So we can't even assert that we don't have a certain type of it as we do with decl types, paramater count, virtual etc. So instead introduce a class that explicitly contains a list of static fns that will return false that you can guard against. If and when a feature becomes implemented simply changing this return to true will cause compilation to fail at all the points in which we noted that we needed to address.

As implementing more struct stuff, we have to teach about linkage to do more accurate CIR codegen. This change makes clang to generate linkage information and MLIR's visibility is now computed based on it.

CodeGen does not use cir::FuncOp just yet, patch a few places that to keep using mlir::FuncOp for now. --- mlir/include/mlir/Dialect/CIR/IR/CIRDialect.h | 2 + mlir/include/mlir/Dialect/CIR/IR/CIROps.td | 114 +++++++++- mlir/lib/Dialect/CIR/IR/CIRDialect.cpp | 213 +++++++++++++++++- .../Dialect/CIR/Transforms/LifetimeCheck.cpp | 2 +- 4 files changed, 314 insertions(+), 17 deletions(-) diff --git a/mlir/include/mlir/Dialect/CIR/IR/CIRDialect.h b/mlir/include/mlir/Dialect/CIR/IR/CIRDialect.h index 9f4aa30cee4d..aa3eeafde1b0 100644 --- a/mlir/include/mlir/Dialect/CIR/IR/CIRDialect.h +++ b/mlir/include/mlir/Dialect/CIR/IR/CIRDialect.h @@ -18,7 +18,9 @@ #include "mlir/IR/BuiltinTypes.h" #include "mlir/IR/Dialect.h" #include "mlir/IR/OpDefinition.h" +#include "mlir/Interfaces/CallInterfaces.h" #include "mlir/Interfaces/ControlFlowInterfaces.h" +#include "mlir/Interfaces/FunctionInterfaces.h" #include "mlir/Interfaces/InferTypeOpInterface.h" #include "mlir/Interfaces/LoopLikeInterface.h" #include "mlir/Interfaces/SideEffectInterfaces.h" diff --git a/mlir/include/mlir/Dialect/CIR/IR/CIROps.td b/mlir/include/mlir/Dialect/CIR/IR/CIROps.td index ea9e5f3d9e93..cb74cae0ee9a 100644 --- a/mlir/include/mlir/Dialect/CIR/IR/CIROps.td +++ b/mlir/include/mlir/Dialect/CIR/IR/CIROps.td @@ -18,14 +18,17 @@ include "mlir/Dialect/CIR/IR/CIRDialect.td" include "mlir/Dialect/CIR/IR/CIRTypes.td" include "mlir/Dialect/CIR/IR/CIRAttrs.td" -include "mlir/IR/EnumAttr.td" -include "mlir/IR/SymbolInterfaces.td" -include "mlir/IR/BuiltinAttributeInterfaces.td" +include "mlir/Interfaces/CallInterfaces.td" include "mlir/Interfaces/ControlFlowInterfaces.td" -include "mlir/Interfaces/LoopLikeInterface.td" +include "mlir/Interfaces/FunctionInterfaces.td" include "mlir/Interfaces/InferTypeOpInterface.td" +include "mlir/Interfaces/LoopLikeInterface.td" include "mlir/Interfaces/SideEffectInterfaces.td" +include "mlir/IR/BuiltinAttributeInterfaces.td" +include "mlir/IR/EnumAttr.td" +include "mlir/IR/SymbolInterfaces.td" + //===----------------------------------------------------------------------===// // CIR Ops //===----------------------------------------------------------------------===// @@ -324,7 +327,7 @@ def StoreOp : CIR_Op<"store", [ // ReturnOp //===----------------------------------------------------------------------===// -def ReturnOp : CIR_Op<"return", [HasParent<"FuncOp, ScopeOp, IfOp, SwitchOp, LoopOp">, +def ReturnOp : CIR_Op<"return", [HasParent<"mlir::FuncOp, ScopeOp, IfOp, SwitchOp, LoopOp">, Terminator]> { let summary = "Return from function"; let description = [{ @@ -1098,4 +1101,105 @@ def StructElementAddr : CIR_Op<"struct_element_addr"> { // FIXME: add verifier. } +//===----------------------------------------------------------------------===// +// FuncOp +//===----------------------------------------------------------------------===// + +def FuncOp : CIR_Op<"func", [ + AutomaticAllocationScope, CallableOpInterface, FunctionOpInterface, + IsolatedFromAbove, Symbol +]> { + let summary = "Declare or define a function"; + let description = [{ + + Similar to `mlir::FuncOp` built-in: + > Operations within the function cannot implicitly capture values defined + > outside of the function, i.e. Functions are `IsolatedFromAbove`.

This tool was brought together by Jingsong Shang. - Make cir-tidy tool build CIR out of clangAST and allow lifetime checker runs on generated CIR. - Add python script to check cir-tidy result. - The current implementation runs lifetime checker with no preset options in default. More options will be supported through command line interface. The cir-tidy tool accepts options in two ways, either config string using CLI or config file. One example of running cir-tidy + cir-lifetime-check looks like: ``` ./cir-tidy source.cpp -checks='-*, cir-lifetime-check' -config="{CheckOptions: [{key: 'cir-lifetime-check.RemarksList', value: 'None'}, {key: 'cir-lifetime-check.HistoryList', value: 'invalid;null'}]}" -- ``` Using ninja, cir-tidy is accessible over these instructions: - Enable clang-tools build `-DLLVM_ENABLE_PROJECTS="...;clang-tools-extra"` - To build: `ninja cir-tidy` - To run tests: `ninja check-clang-extra-cir-tidy` --- clang-tools-extra/clang-tidy/CMakeLists.txt | 1 + .../clang-tidy/cir-tidy/CIRASTConsumer.cpp | 83 +++ .../clang-tidy/cir-tidy/CIRASTConsumer.h | 24 + .../clang-tidy/cir-tidy/CIRTidy.cpp | 112 ++++ .../clang-tidy/cir-tidy/CIRTidy.h | 59 +++ .../clang-tidy/cir-tidy/CMakeLists.txt | 55 ++ .../clang-tidy/cir-tidy/tool/CIRTidyMain.cpp | 483 ++++++++++++++++++ .../clang-tidy/cir-tidy/tool/CIRTidyMain.h | 23 + .../cir-tidy/tool/CIRTidyToolMain.cpp | 21 + .../clang-tidy/cir-tidy/tool/CMakeLists.txt | 49 ++ .../test/cir-tidy/check_cir_tidy.py | 177 +++++++ .../test/cir-tidy/lifetime-basic.cpp | 16 + clang-tools-extra/test/lit.cfg.py | 5 + clang/include/clang/CIR/Dialect/Passes.h | 4 + .../CIR/Dialect/Transforms/LifetimeCheck.cpp | 28 +- 15 files changed, 1138 insertions(+), 2 deletions(-) create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/CIRASTConsumer.cpp create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/CIRASTConsumer.h create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/CIRTidy.cpp create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/CIRTidy.h create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/CMakeLists.txt create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/tool/CIRTidyMain.cpp create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/tool/CIRTidyMain.h create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/tool/CIRTidyToolMain.cpp create mode 100644 clang-tools-extra/clang-tidy/cir-tidy/tool/CMakeLists.txt create mode 100644 clang-tools-extra/test/cir-tidy/check_cir_tidy.py create mode 100644 clang-tools-extra/test/cir-tidy/lifetime-basic.cpp diff --git a/clang-tools-extra/clang-tidy/CMakeLists.txt b/clang-tools-extra/clang-tidy/CMakeLists.txt index 93117cf1d637..c401dd414e70 100644 --- a/clang-tools-extra/clang-tidy/CMakeLists.txt +++ b/clang-tools-extra/clang-tidy/CMakeLists.txt @@ -111,6 +111,7 @@ set(ALL_CLANG_TIDY_CHECKS ${ALL_CLANG_TIDY_CHECKS} PARENT_SCOPE) add_subdirectory(plugin) add_subdirectory(tool) add_subdirectory(utils) +add_subdirectory(cir-tidy) if (NOT LLVM_INSTALL_TOOLCHAIN_ONLY) install(DIRECTORY . diff --git a/clang-tools-extra/clang-tidy/cir-tidy/CIRASTConsumer.cpp b/clang-tools-extra/clang-tidy/cir-tidy/CIRASTConsumer.cpp new file mode 100644 index 000000000000..2f022995fdbe --- /dev/null +++ b/clang-tools-extra/clang-tidy/cir-tidy/CIRASTConsumer.cpp @@ -0,0 +1,83 @@ +#include "CIRASTConsumer.h" + +#include "clang/CIR/Dialect/Passes.h" +#include "mlir/IR/BuiltinOps.h" +#include "../utils/OptionsUtils.h" + +#include "mlir/IR/MLIRContext.h" +#include "mlir/Pass/Pass.h" +#include "mlir/Pass/PassManager.h" +#include + +using namespace clang;

This patch adds support for the C-specific scenario. Since both C and C++ share code gen paths for unary negation, the C cases are handled by casting the boolean type that is already generated for the C++ cases to an int. The following additions were made: - Added C style unary negation test case. - Updated CIR cast to support bool_to_int conversions. - Lowering bool_to_int conversion as a ZExt operation. ghstack-source-id: b721bd66c9d6dad6b0d03d22de21f29cbf97838b Pull Request resolved: https://github.com/llvm/clangir/pull/110 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 4 ++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 4 +++ clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 8 +++-- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 8 +++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 8 +++++ clang/test/CIR/CodeGen/unary.c | 28 +++++++++++++++ clang/test/CIR/Lowering/unary-not.cir | 34 +++++++++++++++++++ 7 files changed, 91 insertions(+), 3 deletions(-) create mode 100644 clang/test/CIR/CodeGen/unary.c diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index dd2dc709593a..1e502d38c15f 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -51,13 +51,15 @@ def CK_FloatToIntegral : I32EnumAttrCase<"float_to_int", 7>;

The `VoidPtrTy` and `UInt8PtrTy` type cache variables no longer share a union, as they cannot be considered the same in terms of CIR types (`!cir.ptr` is not equivalent to `!cir.ptr`). Due to this pointer differentiation, improper occurrences of `!cir.int` are replaced with `!cir.void` where applicable. This was mostly done in coroutine-related builtin calls. Return values for `cir.ternary` operations are now optional allowing `!cir.void` return types.

14c56d1b281916f184ebc10e5d14502cbc4ea62e Mon Sep 17 00:00:00 2001 From: Vinicius Couto Espindola Date: Sat, 24 Jun 2023 19:59:19 -0300 Subject: [PATCH 1015/2301] [CIR][CIRGen][Lowering] Restrict FuncType to exactly one return type Updates FuncType table gen definition to restrict the number of return types to exactly one. Patches FuncOp, CallOp, and codegen builders to work with the new function type definition. Empty results in FuncType builders are replaced by void types. Void function definitions can be parsed in three different ways: - No return type specified: the return type is implicitly void - Return type specified as void: the return type is explicitly void - Return type specified as empty: the return type is implicitly void Some verification checks are removed since they are now implicitly checked. Added lowering for void types in both direct and indirect lowering. ghstack-source-id: 5468006bd0e0ed27be9e9f1a32ee6371a9d9c237 Pull Request resolved: https://github.com/llvm/clangir/pull/118 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 12 ++- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 22 +++--- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 3 +- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 7 +- clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 15 ++-- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 78 ++++++++++--------- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 16 ++-- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 11 ++- .../Lowering/ThroughMLIR/LowerCIRToMLIR.cpp | 13 ++-- clang/test/CIR/IR/func.cir | 10 +++ clang/test/CIR/IR/invalid.cir | 33 +++++++- 11 files changed, 135 insertions(+), 85 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index af7bacca1806..27453ed60304 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -1464,7 +1464,9 @@ def FuncOp : CIR_Op<"func", [ /// Returns the results types that the callable region produces when /// executed.

The codegen works as follows: - A no-proto declaration is found and defined in CIR as a function that can take any number of arguments. - Calls to the function are generated as direct calls that can take any number of arguments. - If the function definition is found, the calls the no-proto declaration is replaced by its definition and any call is patched to have the correct type. CIR's verifier will catch any type error. - If no definition is found, a type error occurs. Invalid calls and external definitions for no-proto declarations are not yet handled. ghstack-source-id: bb06823126ea3e4ba10fa985fd67375295b02b8f Pull Request resolved: https://github.com/llvm/clangir/pull/122 --- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 5 ++ clang/lib/CIR/CodeGen/CIRGenCall.cpp | 20 ++++- clang/lib/CIR/CodeGen/CIRGenCall.h | 6 ++ clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 23 +++--- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 81 ++++++++++++++++++- clang/lib/CIR/CodeGen/CIRGenModule.h | 3 + clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 13 ++- clang/lib/CIR/CodeGen/CIRGenTypes.h | 3 + .../CodeGen/UnimplementedFeatureGuarding.h | 5 ++ clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 6 ++ clang/test/CIR/CodeGen/no-proto-is-void.cpp | 13 +++ clang/test/CIR/CodeGen/no-prototype.c | 22 +++++ 12 files changed, 177 insertions(+), 23 deletions(-) create mode 100644 clang/test/CIR/CodeGen/no-proto-is-void.cpp create mode 100644 clang/test/CIR/CodeGen/no-prototype.c diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.h b/clang/lib/CIR/CodeGen/CIRGenBuilder.h index 97b707a06607..26649f274174 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuilder.h +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.h @@ -219,6 +219,11 @@ class CIRGenBuilderTy : public mlir::OpBuilder { return getPointerTo(getPointerTo(fnTy));

Checking if a value exists is a matter of checking if the type is null. The Optional wrapper was causing a bug in the `CIRGenModule::buildGlobal` method. If an empty type (`mlir::Type{}`) was passed as `Ty`, the `if (!ty)` clause would evalute to true, because the `!` operator would simply validate that there was a `mlir::Type` in the optional wrapper. Then the code gen would continue and try to emit an invalid type. This patch removes the wrapper, which ensures that the `!Ty` clause now checks if the given `mlir::Type` is an empty type. In that case, it generates a real type from the AST Type: ``` if (!Ty) Ty = getTypes().convertTypeForMem(ASTTy); ``` ghstack-source-id: 345e49cd75ef0c682b4089121bc4f8ce0a29167f Pull Request resolved: https://github.com/llvm/clangir/pull/132 --- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 8 +++----- clang/lib/CIR/CodeGen/CIRGenModule.h | 5 ++--- 2 files changed, 5 insertions(+), 8 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenModule.cpp b/clang/lib/CIR/CodeGen/CIRGenModule.cpp index 8c5d6802428e..e1c0d13ee139 100644 --- a/clang/lib/CIR/CodeGen/CIRGenModule.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenModule.cpp @@ -662,8 +662,7 @@ CIRGenModule::getOrCreateCIRGlobal(StringRef MangledName, mlir::Type Ty, return GV; } -mlir::cir::GlobalOp CIRGenModule::buildGlobal(const VarDecl *D, - std::optional Ty, +mlir::cir::GlobalOp CIRGenModule::buildGlobal(const VarDecl *D, mlir::Type Ty, ForDefinition_t IsForDefinition) { assert(D->hasGlobalStorage() && "Not a global variable"); QualType ASTTy = D->getType(); @@ -671,7 +670,7 @@ mlir::cir::GlobalOp CIRGenModule::buildGlobal(const VarDecl *D, Ty = getTypes().convertTypeForMem(ASTTy); StringRef MangledName = getMangledName(D); - return getOrCreateCIRGlobal(MangledName, *Ty, ASTTy.getAddressSpace(), D, + return getOrCreateCIRGlobal(MangledName, Ty, ASTTy.getAddressSpace(), D, IsForDefinition); } @@ -681,8 +680,7 @@ mlir::cir::GlobalOp CIRGenModule::buildGlobal(const VarDecl *D, /// If IsForDefinition is true, it is guaranteed that an actual global with type /// Ty will be returned, not conversion of a variable with the same mangled name /// but some other type. -mlir::Value CIRGenModule::getAddrOfGlobalVar(const VarDecl *D, - std::optional Ty, +mlir::Value CIRGenModule::getAddrOfGlobalVar(const VarDecl *D, mlir::Type Ty, ForDefinition_t IsForDefinition) { assert(D->hasGlobalStorage() && "Not a global variable"); QualType ASTTy = D->getType(); diff --git a/clang/lib/CIR/CodeGen/CIRGenModule.h b/clang/lib/CIR/CodeGen/CIRGenModule.h index a5066e1284fb..2737806d87cc 100644 --- a/clang/lib/CIR/CodeGen/CIRGenModule.h +++ b/clang/lib/CIR/CodeGen/CIRGenModule.h @@ -183,8 +183,7 @@ class CIRGenModule : public CIRGenTypeCache { const VarDecl *D, ForDefinition_t IsForDefinition = NotForDefinition); - mlir::cir::GlobalOp buildGlobal(const VarDecl *D, - std::optional Ty, + mlir::cir::GlobalOp buildGlobal(const VarDecl *D, mlir::Type Ty, ForDefinition_t IsForDefinition); /// TODO(cir): once we have cir.module, add this as a convenience method @@ -215,7 +214,7 @@ class CIRGenModule : public CIRGenTypeCache { /// global with type Ty will be returned, not conversion of a variable with /// the same mangled name but some other type. mlir::Value - getAddrOfGlobalVar(const VarDecl *D, std::optional Ty = {}, + getAddrOfGlobalVar(const VarDecl *D, mlir::Type Ty = {}, ForDefinition_t IsForDefinition = NotForDefinition); CharUnits From 9b27262bdef453c10657eac471aae557fb421e3a Mon Sep 17 00:00:00 2001 From: Vinicius Couto Espindola Date: Mon, 26 Jun 2023 21:12:59 -0300 Subject: [PATCH 1027/2301] [CIR][CIRGen] Add support for static global variables Implements the required changes to support static global variables, ensuring they present the proper linkage type in CIR.

A APInt is used as the storage type for the index, alongside a custom builder to abstract the APInt object creation. Before, we only passed the name of the field to cir.struct_element_addr, which was not very useful since it couldn't be used to recover the index of the member being accessed. This index is essential for lowering CIR to LLVM, as LLVM needs to know which element is being accessed in the struct data aggregate. ghstack-source-id: fa68727f9bd65016647d7ae3acbbf1b109fa79ec Pull Request resolved: https://github.com/llvm/clangir/pull/148 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 20 ++++++++++++++++++- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 3 ++- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 15 ++++++++------ clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 8 ++++---- clang/lib/CIR/CodeGen/CIRGenFunction.h | 5 +++-- clang/test/CIR/CodeGen/String.cpp | 10 +++++----- clang/test/CIR/CodeGen/agg-init.cpp | 10 +++++----- clang/test/CIR/CodeGen/assign-operator.cpp | 8 ++++---- .../CodeGen/ctor-member-lvalue-to-rvalue.cpp | 4 ++-- clang/test/CIR/CodeGen/derived-to-base.cpp | 2 +- clang/test/CIR/CodeGen/lambda.cpp | 8 ++++---- clang/test/CIR/CodeGen/rangefor.cpp | 6 +++--- clang/test/CIR/CodeGen/struct.cpp | 10 +++++----- clang/test/CIR/CodeGen/unary-deref.cpp | 2 +- 14 files changed, 67 insertions(+), 44 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index dcdbce981fc5..8d94edda23c8 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -1383,6 +1383,9 @@ def StructElementAddr : CIR_Op<"struct_element_addr"> { The `cir.struct_element_addr` operaration gets the address of a particular named member from the input struct. + It expects a pointer to the base struct as well as the name of the member + and its field index. + Example: ```mlir !ty_22struct2EBar22 = type !cir.struct<"struct.Bar", i32, i8> @@ -1397,10 +1400,25 @@ def StructElementAddr : CIR_Op<"struct_element_addr"> { let arguments = (ins Arg:$struct_addr, - StrAttr:$member_name); + StrAttr:$member_name, + IndexAttr:$member_index); let results = (outs Res:$result); + let builders = [ + OpBuilder<(ins "Type":$type, "Value":$value, "llvm::StringRef":$name, + "unsigned":$index), + [{ + mlir::APInt fieldIdx(64, index); + build($_builder, $_state, type, value, name, fieldIdx); + }]> + ]; + + let extraClassDeclaration = [{ + /// Return the index of the struct member being accessed. + uint64_t getIndex() { return getMemberIndex().getZExtValue(); } + }]; + // FIXME: add verifier. } diff --git a/clang/lib/CIR/CodeGen/CIRGenClass.cpp b/clang/lib/CIR/CodeGen/CIRGenClass.cpp index 54d3036d1459..8e59bb618e1c 100644 --- a/clang/lib/CIR/CodeGen/CIRGenClass.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenClass.cpp @@ -208,7 +208,8 @@ static void buildLValueForAnyFieldInitialization(CIRGenFunction &CGF, if (MemberInit->isIndirectMemberInitializer()) { llvm_unreachable("NYI"); } else { - LHS = CGF.buildLValueForFieldInitialization(LHS, Field, Field->getName()); + LHS = CGF.buildLValueForFieldInitialization(LHS, Field, Field->getName(), + Field->getFieldIndex()); } } diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index 7fb9e6a8deac..7185655ba2c6 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -52,7 +52,8 @@ static Address buildPreserveStructAccess(CIRGenFunction &CGF, LValue base, /// doesn't necessarily have the right type. static Address buildAddrOfFieldStorage(CIRGenFunction &CGF, Address Base, const FieldDecl *field, - llvm::StringRef fieldName) { + llvm::StringRef fieldName, + unsigned fieldIndex) { if (field->isZeroSize(CGF.getContext())) llvm_unreachable("NYI"); @@ -65,7 +66,7 @@ static Address buildAddrOfFieldStorage(CIRGenFunction &CGF, Address Base, // which do not currently carry the name, so it can be passed down from the // CaptureStmt. auto sea = CGF.getBuilder().create( - loc, fieldPtr, Base.getPointer(), fieldName); + loc, fieldPtr, Base.getPointer(), fieldName, fieldIndex); // TODO: We could get the alignment from the CIRGenRecordLayout, but given the // member name based lookup of the member here we probably shouldn't be.

The main benefit of this is to utilize the CIR attribute interface to handle CIR-specific attributes such as `cir.extra`. Other advantages at this time, besides the cir attribute support, could be that we can go directly from CIR to LLVMIR without exposing the intermediate MLIR LLVM dialect form. Previously `cir-tool` emit the LLVM dialect form and `milr-translate` took it from there. Now `cir-translate` can directly take CIR and yield LLVMIR. I'm also renaming `cir-tool` to `cir-opt` which eventually would be just a CIR-to-CIR transformer, but for now I'm keeping the functionality of CIR to LLVM dialect. So, `cir-opt` will do all CIR-to-CIR transforms, just like LLVM `opt` or `mlir-opt`, and `cir-translate` will handle CIR to LLVMIR translation, and LLVMIR-to-LLVMIR transforms, like the LLVM `llc` or the `mlir-translate` --- clang/include/clang/CIR/LowerToLLVM.h | 1 -

Mixing CIR to LLVM IR translation with codegen tests, or with CIR to LLVM Dialect lowering tests, makes it harder to understand what is being tested and requires the same file to go through multiple tools. This patch creates a separate `clang/tests/CIR/Translation` folder dedicated strictly to CIR's LLVM IR translation interface. While `tests/Lowering` should validate the `lowerDirectlyFromCIRToLLVMIR` pass, `tests/Translation` should validate `CIRDialectLLVMIRTranslationInterface`. --- clang/test/CIR/CodeGen/pointer.cpp | 4 ---- clang/test/CIR/CodeGen/struct.c | 4 ---- clang/test/CIR/Translation/zeroinitializer.cir | 12 ++++++++++++ 3 files changed, 12 insertions(+), 8 deletions(-) create mode 100644 clang/test/CIR/Translation/zeroinitializer.cir diff --git a/clang/test/CIR/CodeGen/pointer.cpp b/clang/test/CIR/CodeGen/pointer.cpp index 06245f06b32b..2ac11cd42e32 100644 --- a/clang/test/CIR/CodeGen/pointer.cpp +++ b/clang/test/CIR/CodeGen/pointer.cpp @@ -1,10 +1,6 @@ // RUN: %clang_cc1 -triple x86_64-unknown-linux-gnu -fclangir -emit-cir %s -o %t.cir // RUN: FileCheck --input-file=%t.cir %s -// FIXME(cir): Move the test below to lowering and us a separate tool to lower from CIR to LLVM IR. -// RUN: %clang_cc1 -triple x86_64-unknown-linux-gnu -fclangir -emit-llvm %s -o %t.ll -// RUN: FileCheck --input-file=%t.ll --check-prefix=LLVM %s // Global pointer should be zero initialized by default. int *ptr; // CHECK: cir.global external @ptr = #cir.null : !cir.ptr -// LLVM: @ptr = global ptr null diff --git a/clang/test/CIR/CodeGen/struct.c b/clang/test/CIR/CodeGen/struct.c index a6c3d8736c58..cc3107d02849 100644 --- a/clang/test/CIR/CodeGen/struct.c +++ b/clang/test/CIR/CodeGen/struct.c @@ -1,8 +1,5 @@ // RUN: %clang_cc1 -triple x86_64-unknown-linux-gnu -fclangir -emit-cir %s -o %t.cir // RUN: FileCheck --input-file=%t.cir %s -// FIXME(cir): Move the test below to lowering and us a separate tool to lower from CIR to LLVM IR. -// RUN: %clang_cc1 -triple x86_64-unknown-linux-gnu -fclangir -emit-llvm %s -o %t.ll -// RUN: FileCheck --input-file=%t.ll --check-prefix=LLVM %s struct Bar { int a; @@ -31,4 +28,3 @@ void baz(void) { // Check if global structs are zero-initialized. // CHECK: cir.global external @bar = #cir.zero : !ty_22struct2EBar22 -// LLVM: @bar = global %struct.Bar zeroinitializer diff --git a/clang/test/CIR/Translation/zeroinitializer.cir b/clang/test/CIR/Translation/zeroinitializer.cir new file mode 100644 index 000000000000..63750fee10cb --- /dev/null +++ b/clang/test/CIR/Translation/zeroinitializer.cir @@ -0,0 +1,12 @@ +// RUN: cir-translate %s -cir-to-llvmir -o %t.ll +// RUN: FileCheck --input-file=%t.ll %s + +module { + // Should lower #cir.zero on structs to a zeroinitializer. + llvm.mlir.global external @bar() {addr_space = 0 : i32, cir.initial_value = #cir.zero : !llvm.struct<"struct.S", (i8, i32)>} : !llvm.struct<"struct.S", (i8, i32)> + // CHECK: @bar = global %struct.S zeroinitializer + + // Should lower #cir.null on pointers to a null initializer. + llvm.mlir.global external @ptr() {addr_space = 0 : i32, cir.initial_value = #cir.zero : !llvm.ptr} : !llvm.ptr + // CHECK: @ptr = global ptr null +} From 6c1d814dc249038860f45ae99f06b1bd303ba936 Mon Sep 17 00:00:00 2001 From: Bruno Cardoso Lopes Date: Fri, 14 Jul 2023 00:02:13 -0300 Subject: [PATCH 1086/2301] [CIR][LifetimeCheck] Use cir.struct_element_addr to track exploded fields This adds exploded members into pmap, fix name printing for those, but doesn't touch aggregate initialization just yet.

This allows the context to have one or two locations for distinguishing between the start and end of the scope. Fixes a bug where a mlir::Location was wrongly casted to a mlir::FusedLoc when building the scope surrounding if statements. In the rare case where the if statement originates from a preprocessor macro definition, the location where the macro is expanded is used as the source location for both the start and the end of the range. Once these locations are fused, MLIR automatically detects the duplicated start and end locations and merges them resulting in single a regular location. This patch allows the if statement to have a single location as its "begin" and "end" locations. Note: spelling locations are not tracked due to performance issues. --- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 55 ++++--------- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 11 +-- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 80 +++---------------- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenFunction.h | 13 ++- clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 53 ++---------- clang/test/CIR/CodeGen/spelling-locations.cpp | 29 +++++++ 7 files changed, 77 insertions(+), 168 deletions(-) create mode 100644 clang/test/CIR/CodeGen/spelling-locations.cpp diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index ea83cd212ce7..42c5d46f8513 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -1830,18 +1830,8 @@ CIRGenFunction::buildConditionalBlocks(const AbstractConditionalOperator *E, .create( loc, condV, /*trueBuilder=*/ [&](mlir::OpBuilder &b, mlir::Location loc) { - // FIXME: abstract all this massive location handling elsewhere. - SmallVector locs;

This caused type mismatches since the name of the StructType would be dropped. Since `cir.typeinfo` depended on this broken parsing method to work, it was also fixed to use a `ArrayAttr` instead of a `cir.const_struct` to store its values. To simplify parsing and printing struct member on both `cir.typeinfo` and `cir.const_struct`, the custom `ConstStructMembers` parser/printer was renamed to `StructMembers` and is now used on both attributes. It was also refactored to patch malformed spacing between members and to simplify the code. ghstack-source-id: 1c913c6c00b2826fd0dac3dd18e7cb56bfe2e737 Pull Request resolved: https://github.com/llvm/clangir/pull/200 --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 12 ++-- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 2 +- clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 60 +++++++------------ clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 8 +-- clang/test/CIR/CodeGen/agg-init.cpp | 2 +- clang/test/CIR/CodeGen/struct.c | 2 +- clang/test/CIR/CodeGen/vtable-rtti.cpp | 2 +- clang/test/CIR/IR/global.cir | 9 +-- clang/test/CIR/IR/invalid.cir | 4 +- clang/test/CIR/IR/struct.cir | 20 ++++--- 10 files changed, 55 insertions(+), 66 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index bdc6cd276f48..726bcfc3cc2a 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -175,9 +175,7 @@ def ConstStructAttr : CIR_Attr<"ConstStruct", "const_struct", ]; let assemblyFormat = [{ -

It currently only covers C++ to CIR generation. The corresponding LLVM lowering will be in a follow-up commit. A motivating example is ``` class Init { friend class ios_base; public: Init(bool); ~Init(); private: static bool _S_synced_with_stdio; }; static Init ioinit(true); ``` Unlike what the default Clang codegen generates LLVM that detaches the initialization code from the global var definition (like below), we are taking a different approach that keeps them together, which we think will make the later dataflow analysis/transform easier. ``` @_ZL8ioinit = internal global %class.Init zeroinitializer, align 1, !dbg !0 define internal void @cxx_global_var_init() #0 section ".text.startup" !dbg !23 { entry: call void @_ZN4InitC2Ev(ptr noundef nonnull align 1 dereferenceable(1) @_ZL8ioinit), !dbg !27 %0 = call i32 @cxa_atexit(ptr @_ZN4InitD1Ev, ptr @_ZL8ioinit, ptr @dso_handle) #3, !dbg !29 ret void, !dbg !27 } ``` So on CIR, we have something like: ``` cir.global "private" internal @_ZL8__ioinit = ctor : !ty_22class2EInit22 { %0 = cir.get_global @_ZL8__ioinit : cir.ptr loc(#loc8) %1 = cir.const(#true) : !cir.bool loc(#loc5) cir.call @_ZN4InitC1Eb(%0, %1) : (!cir.ptr, !cir.bool) -> () loc(#loc6) } ``` The destructor support will also be in a separate change. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 18 +-- clang/lib/CIR/CodeGen/CIRGenCXX.cpp | 45 +++++++ clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenDeclCXX.cpp | 51 +++++++- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 11 +- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 8 +- clang/lib/CIR/CodeGen/CIRGenFunction.h | 10 +- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 30 ++++- clang/lib/CIR/CodeGen/CIRGenModule.h | 8 ++ clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 124 ++++++++++++++----- clang/test/CIR/CodeGen/static.cpp | 24 ++++ clang/test/CIR/IR/global.cir | 13 ++ 12 files changed, 291 insertions(+), 55 deletions(-) create mode 100644 clang/test/CIR/CodeGen/static.cpp diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index b206d506da5d..e61b3d8e8c8b 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -571,11 +571,12 @@ def YieldOpKind : I32EnumAttr< def YieldOp : CIR_Op<"yield", [ReturnLike, Terminator, ParentOneOf<["IfOp", "ScopeOp", "SwitchOp", "LoopOp", "AwaitOp", - "TernaryOp"]>]> { + "TernaryOp", "GlobalOp"]>]> { let summary = "Terminate CIR regions"; let description = [{ The `cir.yield` operation terminates regions on different CIR operations: - `cir.if`, `cir.scope`, `cir.switch`, `cir.loop`, `cir.await` and `cir.ternary`. + `cir.if`, `cir.scope`, `cir.switch`, `cir.loop`, `cir.await`, `cir.ternary` + and `cir.global`.

The idea is to replace `cir.yield break` and `cir.yield continue` with the branch operations to the corresponding blocks. Note, that we need to ignore nesting loops and don't touch `break` in switch operations. Also, `yield` from `if` need to be considered only when it's not the loop `yield` and `continue` in switch is ignored since it's processed in the loops lowering.

There's no reason it needs to be that way - add a CIRModule to clang-tidy and make the lifetime checker its first check. Some of the way this was built was inspired in CLANG_TIDY_ENABLE_STATIC_ANALYZER Once we can fully migrate deps from cir-tidy, we should remove it in favor of this. --- clang-tools-extra/clang-tidy/CMakeLists.txt | 6 + clang-tools-extra/clang-tidy/ClangTidy.cpp | 13 ++ .../clang-tidy/ClangTidyForceLinker.h | 7 + .../clang-tidy/cir/CIRASTConsumer.cpp | 183 ++++++++++++++++++ .../clang-tidy/cir/CIRASTConsumer.h | 28 +++ .../clang-tidy/cir/CIRTidyModule.cpp | 34 ++++ .../clang-tidy/cir/CMakeLists.txt | 62 ++++++ clang-tools-extra/clang-tidy/cir/Lifetime.cpp | 28 +++ clang-tools-extra/clang-tidy/cir/Lifetime.h | 28 +++ .../clang-tidy/clang-tidy-config.h.cmake | 2 + .../checkers/cir/lifetime-basic.cpp | 39 ++++ .../clang-tidy/checkers/cir/lit.local.cfg | 2 + 12 files changed, 432 insertions(+) create mode 100644 clang-tools-extra/clang-tidy/cir/CIRASTConsumer.cpp create mode 100644 clang-tools-extra/clang-tidy/cir/CIRASTConsumer.h create mode 100644 clang-tools-extra/clang-tidy/cir/CIRTidyModule.cpp create mode 100644 clang-tools-extra/clang-tidy/cir/CMakeLists.txt create mode 100644 clang-tools-extra/clang-tidy/cir/Lifetime.cpp create mode 100644 clang-tools-extra/clang-tidy/cir/Lifetime.h create mode 100644 clang-tools-extra/test/clang-tidy/checkers/cir/lifetime-basic.cpp create mode 100644 clang-tools-extra/test/clang-tidy/checkers/cir/lit.local.cfg diff --git a/clang-tools-extra/clang-tidy/CMakeLists.txt b/clang-tools-extra/clang-tidy/CMakeLists.txt index cab701f0f08d..d998fc56ce21 100644 --- a/clang-tools-extra/clang-tidy/CMakeLists.txt +++ b/clang-tools-extra/clang-tidy/CMakeLists.txt @@ -76,6 +76,9 @@ add_subdirectory(performance) add_subdirectory(portability) add_subdirectory(readability) add_subdirectory(zircon) +if(CLANG_ENABLE_CIR) + add_subdirectory(cir) +endif() set(ALL_CLANG_TIDY_CHECKS clangTidyAndroidModule clangTidyAbseilModule @@ -104,6 +107,9 @@ set(ALL_CLANG_TIDY_CHECKS if(CLANG_TIDY_ENABLE_STATIC_ANALYZER) list(APPEND ALL_CLANG_TIDY_CHECKS clangTidyMPIModule) endif() +if(CLANG_ENABLE_CIR) + list(APPEND ALL_CLANG_TIDY_CHECKS clangTidyCIRModule) +endif() set(ALL_CLANG_TIDY_CHECKS ${ALL_CLANG_TIDY_CHECKS} PARENT_SCOPE) # Other subtargets.

An example is when an array is only partially initialize with #cir.zero attributes. Since we can't just zeroinitialize the whole array, the current #cir.zero attribute amend does not suffice. To simplify the lowering, this patch introduces a new operation that is solely used to generate zeroinitialize LLVM IR constants. ghstack-source-id: a3fd40ec3ce8970ac4e958076cc17d3fac573696 Pull Request resolved: https://github.com/llvm/clangir/pull/218 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 18 ++++++++++++++++++ .../DirectToLLVM/LowerAttrToLLVMIR.cpp | 14 ++++++++++++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 3 +++ clang/test/CIR/Translation/zeroinitializer.cir | 9 +++++++++ 4 files changed, 44 insertions(+) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 27bea737e561..7f45f55eb993 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -1852,4 +1852,22 @@ def VAArgOp : CIR_Op<"va.arg">, let hasVerifier = 0; } +//===----------------------------------------------------------------------===// +// Operations Lowered Directly to LLVM IR +// +// These operations are hacks to get around missing features in LLVM's dialect. +// Use it sparingly and remove it once the features are added. +//===----------------------------------------------------------------------===// + +def ZeroInitConstOp : CIR_Op<"llvmir.zeroinit", [Pure]>, + Results<(outs AnyType:$result)> { + let summary = "Zero initializes a constant value of a given type"; + let description = [{ + This operation circumvents the lack of a zeroinitializer operation in LLVM + Dialect.

The problem with this approach is that it doesn't work when trying to use clang-tidy from clangd. Since clangd plays differently with ASTConsumer's, it's not possible to apply the same approach.

From: Vinicius Couto Espindola Date: Mon, 28 Aug 2023 20:45:14 -0300 Subject: [PATCH 1174/2301] [CIR] Refactor StructElementAddr into GetMemberOp Improves a few aspects of the old CIR GEP equivalent: * Generalize the name to GetMemberOp, since it can be used for unions, classes, structs, and others. * Add custom assembly format to improve readability. * Add a new CIR dialect operation to represent the operation. * Remove redundancy from arguments names (e.g. "member_index" to just "index") for terseness. * Add verifier to check if: * The index is within bounds. * The type is a record (has members to be accessed). * The result type matches the type of the member. * Use CIRGenBuilder when building GetMemberOps. * Also add some getter wrappers. ghstack-source-id:

(#250) - Introduces `CIR/Interfaces/ASTAttrInterfaces` which model API of clang AST nodes, but allows to plugin custom attribute, making `CIR` dialect AST independent. - Extends hierarchy of `DeclAttr`s to model `Decl` attributes more faithfully. - Notably all `CIRASTAttr`s are now created uniformly using `makeAstDeclAttr` which builds corresponding Attribute based on `clang::Decl`. ---

03:59:09 +0300 Subject: [PATCH 1202/2301] [CIR][CodeGen][Bugfix] Generate field index with respect to layout (#263) There is a bug in the code generation: the field index for the `GetMemberOp` is taken from the `FieldDecl`, with no respect to the record layout. One of the manifestation of the bug is the wrong index generated for a field in a derived class that does not take into the account the instance of the base class (that has index 0). You can take a look at the example in `test/CIR/CodeGen/derived-to-base.cpp`, i.e. the current test is not the correct one ``` // CHECK-DAG: !ty_22C23A3ALayer22 = !cir.struct // CHECK-DAG: !ty_22C33A3ALayer22 = !cir.struct) -> cir.ptr // CHECK: %3 = cir.get_member %2[0] {name = "m_C1"} : !cir.ptr -> !cir.ptr> ``` As one can see, the result (of ptr type to `!ty_22C222` ) must have the index `1` in the corresponded struct `ty_22C23A3ALayer22`. Basically the same is done in the `clang/CodeGen/CGExpr.cpp`, so we don't invent something new here. Note, this fix doesn't affect anything related to the usage of `buildPreserveStructAccess` where the `field->getFieldIndex()` is used. --- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 4 +++- clang/test/CIR/CodeGen/derived-to-base.cpp | 2 +- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index a884c9144637..40f2b97ab919 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -271,7 +271,9 @@ LValue CIRGenFunction::buildLValueForField(LValue base, if (!IsInPreservedAIRegion && (!getDebugInfo() || !rec->hasAttr())) { llvm::StringRef fieldName = field->getName(); - unsigned fieldIndex = field->getFieldIndex(); + auto& layout = CGM.getTypes().getCIRGenRecordLayout(field->getParent()); + unsigned fieldIndex = layout.getCIRFieldNo(field); + if (CGM.LambdaFieldToName.count(field)) fieldName = CGM.LambdaFieldToName[field]; addr = buildAddrOfFieldStorage(*this, addr, field, fieldName, fieldIndex); diff --git a/clang/test/CIR/CodeGen/derived-to-base.cpp b/clang/test/CIR/CodeGen/derived-to-base.cpp index 65f881afccfe..03846ca45688 100644 --- a/clang/test/CIR/CodeGen/derived-to-base.cpp +++ b/clang/test/CIR/CodeGen/derived-to-base.cpp @@ -82,7 +82,7 @@ void C3::Layer::Initialize() { // CHECK: cir.scope { // CHECK: %2 = cir.base_class_addr(%1 : cir.ptr ) -> cir.ptr -// CHECK: %3 = cir.get_member %2[0] {name = "m_C1"} : !cir.ptr -> !cir.ptr> +// CHECK: %3 = cir.get_member %2[1] {name = "m_C1"} : !cir.ptr -> !cir.ptr> // CHECK: %4 = cir.load %3 : cir.ptr >, !cir.ptr // CHECK: %5 = cir.const(#cir.ptr : !cir.ptr) : !cir.ptr // CHECK: %6 = cir.cmp(eq, %4, %5) : !cir.ptr, !cir.bool From 567cc39524b12ae768b47eb3789c8464397bd29c Mon Sep 17 00:00:00 2001 From: Keyi Zhang Date: Mon, 18 Sep 2023 22:49:37 -0700 Subject: [PATCH 1203/2301] [CIR][Lowering] Add scf.scope lowering to standard dialects (#262) This PR adds MLIR lowering of `cir.scope`.

Fixes #13 (#268) This is an updated PR for [PR explained in [PR #261](https://github.com/llvm/clangir/pull/261) which now can be safely closed. First of all, let me introduce how do the bitfields looks like in CIR. For the struct `S` defined as following: ``` typedef struct { int a : 4; int b : 27; int c : 17; int d : 2; int e : 15; unsigned f; } S; ``` the CIR type is `!ty_22S22 = !cir.struct` where all the bitfields are packed in the first three storages. Also, the next bugs was fixed: - type mismatch - index out of bounds - single bitfield of size < 8 The cases covered with tests. --- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 64 +++++ clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 232 +++++++++++++++++- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 138 ++++++----- clang/lib/CIR/CodeGen/CIRGenFunction.h | 16 +- clang/lib/CIR/CodeGen/CIRGenRecordLayout.h | 10 + clang/lib/CIR/CodeGen/CIRGenValue.h | 34 +++ .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 9 +- .../CodeGen/UnimplementedFeatureGuarding.h | 1 + clang/test/CIR/CodeGen/bitfields.c | 99 ++++++++ clang/test/CIR/CodeGen/bitfields.cpp | 81 ++++++ 10 files changed, 600 insertions(+), 84 deletions(-) create mode 100644 clang/test/CIR/CodeGen/bitfields.c diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.h b/clang/lib/CIR/CodeGen/CIRGenBuilder.h index 572b85be4c2c..ac54edaa3eaa 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuilder.h +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.h @@ -460,6 +460,11 @@ class CIRGenBuilderTy : public mlir::OpBuilder { return getConstInt( loc, t, isSigned ? intVal.getSExtValue() : intVal.getZExtValue());

Basically, all calls to the `buildLValueForFieldInitialization` are even with the origin codegen `emitLValueForFieldInitialization` calls, i.e. the field index is calculated from the record layout, but not from the decl `field->getFieldIndex()`. Added just one test, because looks like we need to implement some `NYI` features first to test another places e.g. in `CIRGenExprAgg.cpp`, though I could miss something. Anyway, given the original codegen doesn't use `getFieldIndex` in these places, we also should not. All the remaining usages of `getFieldIndex` are ok. --- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 3 +-- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 6 ++++-- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 6 ++---- clang/lib/CIR/CodeGen/CIRGenFunction.h | 3 +-- clang/test/CIR/CodeGen/derived-to-base.cpp | 13 +++++++++++++ 5 files changed, 21 insertions(+), 10 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenClass.cpp b/clang/lib/CIR/CodeGen/CIRGenClass.cpp index 9a550a61f794..b031e93e53c9 100644 --- a/clang/lib/CIR/CodeGen/CIRGenClass.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenClass.cpp @@ -207,8 +207,7 @@ static void buildLValueForAnyFieldInitialization(CIRGenFunction &CGF, if (MemberInit->isIndirectMemberInitializer()) { llvm_unreachable("NYI"); } else { - LHS = CGF.buildLValueForFieldInitialization(LHS, Field, Field->getName(), - Field->getFieldIndex()); + LHS = CGF.buildLValueForFieldInitialization(LHS, Field, Field->getName()); } } diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index 329d5e813d28..9aa4a847ccb4 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -388,13 +388,15 @@ LValue CIRGenFunction::buildLValueForField(LValue base, } LValue CIRGenFunction::buildLValueForFieldInitialization( - LValue Base, const clang::FieldDecl *Field, llvm::StringRef FieldName, - unsigned FieldIndex) { + LValue Base, const clang::FieldDecl *Field, llvm::StringRef FieldName) { QualType FieldType = Field->getType(); if (!FieldType->isReferenceType()) return buildLValueForField(Base, Field); + auto& layout = CGM.getTypes().getCIRGenRecordLayout(Field->getParent()); + unsigned FieldIndex = layout.getCIRFieldNo(Field); + Address V = buildAddrOfFieldStorage(*this, Base.getAddress(), Field, FieldName, FieldIndex); diff --git a/clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp b/clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp index 6b31001144cc..a67eb88b9976 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp @@ -9,7 +9,6 @@ // This contains code to emit Aggregate Expr nodes as CIR code. // //===----------------------------------------------------------------------===// - #include "CIRGenCall.h" #include "CIRGenFunction.h" #include "CIRGenModule.h" @@ -554,7 +553,7 @@ void AggExprEmitter::VisitLambdaExpr(LambdaExpr *E) { // Emit initialization LValue LV = CGF.buildLValueForFieldInitialization( - SlotLV, *CurField, fieldName, CurField->getFieldIndex()); + SlotLV, *CurField, fieldName); if (CurField->hasCapturedVLAType()) { llvm_unreachable("NYI"); } @@ -819,9 +818,8 @@ void AggExprEmitter::VisitCXXParenListOrInitListExpr( if (curInitIndex == NumInitElements && Dest.isZeroed() && CGF.getTypes().isZeroInitializable(ExprToVisit->getType())) break; - LValue LV = CGF.buildLValueForFieldInitialization( - DestLV, field, field->getName(), field->getFieldIndex()); + DestLV, field, field->getName()); // We never generate write-barries for initialized fields. assert(!UnimplementedFeature::setNonGC()); diff --git a/clang/lib/CIR/CodeGen/CIRGenFunction.h b/clang/lib/CIR/CodeGen/CIRGenFunction.h index 1890361eaeb1..3428c7f254df 100644 --- a/clang/lib/CIR/CodeGen/CIRGenFunction.h +++ b/clang/lib/CIR/CodeGen/CIRGenFunction.h @@ -1531,8 +1531,7 @@ class CIRGenFunction : public CIRGenTypeCache { /// stored in the reference.

This essentially involves updating the type converter to drop pointee types and explicitly defining the types loaded/stored/GEPed by LLVM operations. The reasons for this are twofold: - LLVM dialect is currently transitioning to deprecate typed pointers, allowing only opaque pointers. The sooner we transition the fewer changes we will have to make. - Opaque pointers greatly simplify lowering self-references, since all self-references in records are wrapped in a pointer. --- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 34 +++++++++---------- clang/test/CIR/Lowering/dot.cir | 28 +++++++-------- clang/test/CIR/Lowering/globals.cir | 15 +++----- clang/test/CIR/Lowering/hello.cir | 2 +- clang/test/CIR/Lowering/loadstorealloca.cir | 10 ++---- clang/test/CIR/Lowering/loop.cir | 12 +++---- clang/test/CIR/Lowering/scope.cir | 3 +- clang/test/CIR/Lowering/struct.cir | 1 + clang/test/CIR/Lowering/tenary.cir | 7 ++-- clang/test/CIR/Lowering/unary-plus-minus.cir | 12 +++---- clang/test/CIR/Lowering/unions.cir | 6 ++-- 11 files changed, 58 insertions(+), 72 deletions(-) diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index ef51197088fb..d598f6381978 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -197,7 +197,7 @@ mlir::Value lowerCirAttrAsValue(mlir::Operation *parentOp, auto loc = parentOp->getLoc(); auto addressOfOp = rewriter.create( - loc, mlir::LLVM::LLVMPointerType::get(sourceSymbol.getContext()), + loc, mlir::LLVM::LLVMPointerType::get(parentOp->getContext()), sourceSymbol.getSymName()); assert(!globalAttr.getIndices() && "TODO"); @@ -313,7 +313,6 @@ class CIRPtrStrideOpLowering rewriter.replaceOpWithNewOp(ptrStrideOp, resultTy, elementTy, adaptor.getBase(), adaptor.getStride()); - return mlir::success(); } }; @@ -485,12 +484,12 @@ class CIRCastOpLowering : public mlir::OpConversionPattern { matchAndRewrite(mlir::cir::CastOp castOp, OpAdaptor adaptor, mlir::ConversionPatternRewriter &rewriter) const override { auto src = adaptor.getSrc(); + switch (castOp.getKind()) { case mlir::cir::CastKind::array_to_ptrdecay: { const auto ptrTy = castOp.getType().cast(); auto sourceValue = adaptor.getOperands().front(); - auto targetType = - getTypeConverter()->convertType(castOp->getResult(0).getType()); + auto targetType = convertTy(ptrTy); auto elementTy = convertTy(ptrTy.getPointee()); auto offset = llvm::SmallVector{0}; rewriter.replaceOpWithNewOp( @@ -831,17 +830,14 @@ class CIRAllocaLowering mlir::LogicalResult matchAndRewrite(mlir::cir::AllocaOp op, OpAdaptor adaptor, mlir::ConversionPatternRewriter &rewriter) const override { - auto elementTy = getTypeConverter()->convertType(op.getAllocaType()); - mlir::Value one = rewriter.create( op.getLoc(), typeConverter->convertType(rewriter.getIndexType()), rewriter.getIntegerAttr(rewriter.getIndexType(), 1)); - + auto elementTy = getTypeConverter()->convertType(op.getAllocaType()); auto resultTy = mlir::LLVM::LLVMPointerType::get(getContext()); - rewriter.replaceOpWithNewOp( op, resultTy, elementTy, one, op.getAlignmentAttr().getInt()); - return mlir::LogicalResult::success(); + return mlir::success(); } }; @@ -1028,9 +1024,9 @@ class CIRVAStartLowering mlir::LogicalResult matchAndRewrite(mlir::cir::VAStartOp op, OpAdaptor adaptor, mlir::ConversionPatternRewriter &rewriter) const override { - auto i8PtrTy = mlir::LLVM::LLVMPointerType::get(getContext()); + auto opaquePtr = mlir::LLVM::LLVMPointerType::get(getContext()); auto vaList = rewriter.create( - op.getLoc(), i8PtrTy, adaptor.getOperands().front()); + op.getLoc(), opaquePtr, adaptor.getOperands().front()); rewriter.replaceOpWithNewOp(op, vaList); return mlir::success(); } @@ -1043,9 +1039,9 @@ class CIRVAEndLowering : public mlir::OpConversionPattern { mlir::LogicalResult matchAndRewrite(mlir::cir::VAEndOp op, OpAdaptor adaptor, mlir::ConversionPatternRewriter &rewriter) const override { - auto i8PtrTy = mlir::LLVM::LLVMPointerType::get(getContext()); + auto opaquePtr = mlir::LLVM::LLVMPointerType::get(getContext()); auto vaList = rewriter.create( - op.getLoc(), i8PtrTy, adaptor.getOperands().front()); + op.getLoc(), opaquePtr, adaptor.getOperands().front()); rewriter.replaceOpWithNewOp(op, vaList); return mlir::success(); } @@ -1059,11 +1055,11 @@ class CIRVACopyLowering mlir::LogicalResult matchAndRewrite(mlir::cir::VACopyOp op, OpAdaptor adaptor, mlir::ConversionPatternRewriter &rewriter) const override { - auto i8PtrTy = mlir::LLVM::LLVMPointerType::get(getContext()); + auto opaquePtr = mlir::LLVM::LLVMPointerType::get(getContext()); auto dstList = rewriter.create( - op.getLoc(), i8PtrTy, adaptor.getOperands().front()); + op.getLoc(), opaquePtr, adaptor.getOperands().front()); auto srcList = rewriter.create( - op.getLoc(), i8PtrTy, adaptor.getOperands().back()); + op.getLoc(), opaquePtr, adaptor.getOperands().back()); rewriter.replaceOpWithNewOp(op, dstList, srcList); return mlir::success(); } @@ -1777,7 +1773,8 @@ class CIRGetMemberOpLowering // Since the base address is a pointer to an aggregate, the first offset // is always zero.

Here we also skip verification if a field on the given index is also of incomplete type - and we can not compare it with the result type of the operation. Now the next code fails with type mismatch error: ``` typedef struct Node { struct Node* next; } NodeStru; void foo(NodeStru* a) { a->next = 0; } ``` because the result type is kind of full and the type of field is not (for the reasons discussed in #256). Basically, the problem is in the `GetMemberOp` result type generated as following (via `CIRGenTypes::convertType`) `!cir.ptr>} #cir.record.decl.ast>>` where the field type at index differs from the record type - compare with `!cir.ptr>` We just slightly relax the previous solution in #257 - and the compilation won't fail in the case of recursive types.

Wed, 1 Nov 2023 20:13:53 -0300 Subject: [PATCH 1234/2301] [CIR][CIRGen] Refactor StructType builders (#294) Instead of using a single builder for every possible StructType, we now have three builders: identified complete, identified incomplete, and anonymous struct types. This allows us to enforce correctness and to explicitly show the intent when creating a StructType. This patch also adds support for anonymous structs type aliases. When a StructType has no name, it will generate a `ty_anon_` alias. Conflicts are automatically resolved by MLIR. --- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 44 ++++++++++++++++--- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 43 ++++++++++++------ clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 3 +- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 10 +++-- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 7 +-- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 17 ++++++- clang/test/CIR/CodeGen/struct.c | 2 +- clang/test/CIR/CodeGen/vbase.cpp | 1 + clang/test/CIR/CodeGen/vtable-rtti.cpp | 6 +-- clang/test/CIR/IR/aliases.cir | 11 +++-- clang/test/CIR/IR/invalid.cir | 7 +++ 11 files changed, 114 insertions(+), 37 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIRTypes.td b/clang/include/clang/CIR/Dialect/IR/CIRTypes.td index 96078c8bbeb5..7b0c060cabe9 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRTypes.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRTypes.td @@ -115,6 +115,37 @@ def CIR_StructType : CIR_Type<"Struct", "struct", "ASTRecordDeclInterface":$ast );

This is the first step to make StructType mutable, as this feature is not yet supported by tablegen. It's mostly a copy of the tablegen definition, with a few notable differences: - A few embellishments are added to make the code more dev-friendly - Addition of a CIRTypesDetails.h file to keep custom storage definitions - The CIR_AnyCIRType constraint is removed, as it is not used and must be defined in C++ to ensure StructType is a part of it. ghstack-source-id: 5f706dc0a61a4a2ed6e2f20ab0937b1a42bfa9cc Pull Request resolved: https://github.com/llvm/clangir/pull/302 --- clang/include/clang/CIR/Dialect/IR/CIRTypes.h | 119 ++++++++++++++++- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 122 ------------------ .../clang/CIR/Dialect/IR/CIRTypesDetails.h | 83 ++++++++++++ clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 107 +++++++++++++-- 4 files changed, 298 insertions(+), 133 deletions(-) create mode 100644 clang/include/clang/CIR/Dialect/IR/CIRTypesDetails.h diff --git a/clang/include/clang/CIR/Dialect/IR/CIRTypes.h b/clang/include/clang/CIR/Dialect/IR/CIRTypes.h index 1286225f04aa..0d15621e9c61 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRTypes.h +++ b/clang/include/clang/CIR/Dialect/IR/CIRTypes.h @@ -20,10 +20,127 @@ #include "clang/CIR/Interfaces/ASTAttrInterfaces.h" //===----------------------------------------------------------------------===// -// CIR Dialect Types +// CIR Dialect Tablegen'd Types //===----------------------------------------------------------------------===// #define GET_TYPEDEF_CLASSES #include "clang/CIR/Dialect/IR/CIROpsTypes.h.inc" +//===----------------------------------------------------------------------===// +// CIR StructType +// +// The base type for all RecordDecls. +//===----------------------------------------------------------------------===// + +namespace mlir { +namespace cir { + +namespace detail { +struct StructTypeStorage;

The motivation for this is to improve the codegen of CIR in certain scenarios where an incomplete type is used and later completed. These usually leave the IR in an inconsistent state, where there are two records types with the same identifier but different definitions (one complete the other incomplete). For example: ```c++ struct Node { Node *next; }; void test(struct Node n) {} ``` Generates: ```mlir !temp_struct = !cir.struct !full_struct = !cir.struct}> ``` To generate the `Node` struct type, its members must be created first. However, the `next` member is a recursive reference, so it can only be completed after its parent. This generates a temporary incomplete definition of the `Node` type that remains in the code even after the type to which it refers is completed. As a consequence, accessing the `next` member of a `Node` value fetches the old incomplete version of the type which affects CIR's type-checking capabilities. This patch ensures that, once the parent is fully visited, the `next` member can be completed in place, automatically updating any references to it at a low cost. To represent recursive types, the StructType now is equipped with self-references. These are represented by a `cir.struct` type with just the name of the parent struct that it refers to. The same snippet of code will not generate the following CIR IR: ```mlir !full_struct = !cir.struct>}> ``` Summary of the changes made: - Named records are now uniquely identified by their name. An attempt to create a new record with the same will fail. - Anonymous records are uniquely identified by members and other relevant attributes. - StructType has a new `mutate` method that allows it to be mutated after it has been created. Each type can only be mutated if it is identified and incomplete, rendering further changes impossible. - When building a new name StructType, the builder will try to first create, then complete the type, ensuring that: - Inexistent types are created - Existing incomplete types are completed - Existing complete types with matching attributes are reused - Existing complete types with different attributes raise errors - StructType now uses the CyclicParser/Printer guard to avoid infinite recursion and identify when it should print/parse a self-reference. ghstack-source-id: a6d4f650515cbf2d7f6e27d45aae6f768ba44f92 Pull Request resolved: https://github.com/llvm/clangir/pull/303 --- clang/include/clang/CIR/Dialect/IR/CIRTypes.h | 40 +++++- .../clang/CIR/Dialect/IR/CIRTypesDetails.h | 36 ++++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 16 ++- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 2 +- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 50 ++++++- clang/test/CIR/CodeGen/bitfields.cpp | 1 - clang/test/CIR/CodeGen/derived-to-base.cpp | 4 +- clang/test/CIR/CodeGen/dtors.cpp | 4 +- clang/test/CIR/CodeGen/forward-decls.cpp | 125 ++++++++++++++++++ clang/test/CIR/CodeGen/struct.c | 5 +- clang/test/CIR/CodeGen/struct.cpp | 2 +- clang/test/CIR/CodeGen/union.cpp | 1 + clang/test/CIR/CodeGen/vtable-rtti.cpp | 8 +- clang/test/CIR/IR/invalid.cir | 10 ++ clang/test/CIR/IR/struct.cir | 9 ++ 15 files changed, 289 insertions(+), 24 deletions(-) create mode 100644 clang/test/CIR/CodeGen/forward-decls.cpp diff --git a/clang/include/clang/CIR/Dialect/IR/CIRTypes.h b/clang/include/clang/CIR/Dialect/IR/CIRTypes.h index 0d15621e9c61..40a3486e12ee 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRTypes.h +++ b/clang/include/clang/CIR/Dialect/IR/CIRTypes.h @@ -41,9 +41,43 @@ struct StructTypeStorage; /// Each unique clang::RecordDecl is mapped to a `cir.struct` and any object in /// C/C++ that has a struct type will have a `cir.struct` in CIR. +/// +/// There are three possible formats for this type: +/// +/// - Identified and complete structs: unique name and a known body. +/// - Identified and incomplete structs: unique name and unkonwn body. +/// - Anonymous structs: no name and a known body. +/// +/// Identified structs are uniqued by their name, and anonymous structs are +/// uniqued by their body.

Conversions from bool to pointer were following the same code path. But bool-to-int is a different CastKind than int-to-int in CIR, and CIR was failing validation. Fix the integer to pointer conversion code to correctly handle a source type of bool. (A conversion from bool to pointer makes no sense and should never happen in the real world. But it is legal due to bool being sort of an integral type. So we need to support it.) Also, in `ScalarExprEmitter::buildScalarConversion` change a couple not-yet-implemented messages about pointer types into assertion failures.

There is one thing I want to discuss, that's why the PR is marked as a draft now. Looks like I have to introduce some redundant helpers for all these `or` and `shift` operations: while we were in the `CodeGen` area, we used `CIRGenBuilder` and we could easily extend it. I bet we don't want to depend from `CodeGen` in the `LoweringPrepare`. Once it's true. what is a good place for all this common things? As an idea, we could introduce one more layer for builder, with no state involved - just helpers and nothing else.

This patch also fixes other two issues: - An extra index was wrongly added to the global view access. E.g. for an access like `a[0]` would generate a GV with 2 zero indexes. The indexes, however, do not take the pointer wrapping the global type into account. - When assigning the address of a complete type to an incomplete one the complete type would override the incomplete destination type, causing inconsistencies during CodeGen. For example, given `int a[3];` and `int (*ptr_a)[] = &a;`, despite `ptr_a`, in CIR it would be considered complete.

The first is essentially the same method but simplified. The latter was refactored to do only two things: check if the terminator omission of a region is valid and, if so, insert the omitted terminator into the region. The simplifications mostly leverage the fact that we only omit empty yield values in a single-block region. ghstack-source-id: 7b943719ca0fb4ac2d1d29775d7545787c23bcbf Pull Request resolved: https://github.com/llvm/clangir/pull/321 --- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 143 +++++++++--------------- clang/test/CIR/IR/invalid.cir | 6 +- 2 files changed, 58 insertions(+), 91 deletions(-) diff --git a/clang/lib/CIR/Dialect/IR/CIRDialect.cpp b/clang/lib/CIR/Dialect/IR/CIRDialect.cpp index 8f031d611712..5cbd2a594c4b 100644 --- a/clang/lib/CIR/Dialect/IR/CIRDialect.cpp +++ b/clang/lib/CIR/Dialect/IR/CIRDialect.cpp @@ -77,7 +77,7 @@ struct CIROpAsmDialectInterface : public OpAsmDialectInterface { os << (boolAttr.getValue() ?

Next, we fix `yield` lowering for `ifOp` and `switchOp` but didn't cover `scopeOp`, and the same error occurred. This PR fixes this as well.

This is enough to compile this test program. I haven't tried to do anything beyond that yet. ``` typedef int int4 __attribute__((vector_size(16))); int main(int argc, char** argv) { int4 a = { 1, argc, argc + 1, 4 }; int4 b = { 5, argc + 2, argc + 3, 8 }; int4 c = a + b; return c[1]; } ``` This change includes: * Fixed-sized vector types which are parameterized on the element type and the number of elements. For example, `!cir.vector`. (No scalable vector types yet; those will come later.) * New operation `cir.vec` which creates an object of a vector type with the given operands. * New operation `cir.vec_elem` which extracts an element from a vector. (The array subscript operation doesn't work here because the result is an rvalue, not an lvalue.) * Basic binary arithmetic operations on vector types, though only addition has been tested. There are no unary operators, comparison operators, casts, or shuffle operations yet. Those will all come later. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 59 ++++++++++++++++++- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 20 +++++++ clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 33 ++++++++--- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 5 +- .../CodeGen/UnimplementedFeatureGuarding.h | 8 ++- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 25 ++++++++ clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 30 ++++++++-- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 58 ++++++++++++++++-- clang/test/CIR/CodeGen/vectype.cpp | 40 +++++++++++++ clang/test/CIR/IR/invalid.cir | 29 +++++++++ 11 files changed, 285 insertions(+), 26 deletions(-) create mode 100644 clang/test/CIR/CodeGen/vectype.cpp diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index d7379b5bc849..286200844638 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -73,13 +73,18 @@ def CastOp : CIR_Op<"cast", [Pure]> { let description = [{ Apply C/C++ usual conversions rules between values.

Previously, the code example below caused crash in cir verification Lowering to the `llvm` dialect is pretty straightforward: the same logic as before is applied to all the region's blocks with no successors, i.e. we no longer think a case/default region contains only one block. The `CodeGen` part is a little bit tricky. Previously, any sub-statement of `case` or`default`, that was not any of them (i.e. neither `case` nor `default`) was processed with an insertion guard, meaning that the next sub-statement in the same clause was inserted again in the same block as the first one. It would be fine, once sub-statement didn't generate any blocks as well. For instance, ``` void foo(int a) { switch (a) { case 3: return; break; } } ``` The `return` statement actually emit a new block after, where the unreachable code with `break` should be inserted in. That's why we also need to update `lastCaseBlock` while generating `cir.switch` This is quite frequent bug in `llvm-test-suite` --- clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 2 +- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 51 ++++++++++--------- clang/test/CIR/CodeGen/switch.cpp | 16 ++++++ clang/test/CIR/Lowering/switch.cir | 31 +++++++++++ 4 files changed, 74 insertions(+), 26 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenStmt.cpp b/clang/lib/CIR/CodeGen/CIRGenStmt.cpp index 8bf702d4c824..233a1b216283 100644 --- a/clang/lib/CIR/CodeGen/CIRGenStmt.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenStmt.cpp @@ -621,7 +621,6 @@ mlir::LogicalResult CIRGenFunction::buildCaseDefaultCascade( insertFallthrough(*stmt);

break; } } ``` i.e. when some sub statement contains `break` as well. Previously, we did this trick for `loop`: process nested `break`/`continue` statements while `LoopOp` lowering if they don't belong to another `LoopOp` or `SwitchOp`. This is why there is some refactoring here as well, but the idea is stiil the same: we need to process nested operations and emit branches to the proper blocks. This is quite frequent bug in `llvm-test-suite` --- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 100 ++++++++---------- clang/test/CIR/Lowering/switch.cir | 46 ++++++++ 2 files changed, 88 insertions(+), 58 deletions(-) diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index 8b38cbcd7bf7..0dbc64baa491 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -324,6 +324,35 @@ mlir::LLVM::Linkage convertLinkage(mlir::cir::GlobalLinkageKind linkage) { }; } +static void lowerNestedYield(mlir::cir::YieldOpKind targetKind, + mlir::ConversionPatternRewriter &rewriter, + mlir::Region &body, + mlir::Block *dst) { + // top-level yields are lowered in matchAndRewrite of the parent operations + auto isNested = [&](mlir::Operation *op) { + return op->getParentRegion() != &body; + }; + + body.walk( + [&](mlir::Operation *op) { + if (!isNested(op)) + return mlir::WalkResult::advance(); + + // don't process breaks/continues in nested loops and switches + if (isa(*op)) + return mlir::WalkResult::skip(); + + auto yield = dyn_cast(*op); + if (yield && yield.getKind() == targetKind) { + rewriter.setInsertionPoint(op); + rewriter.replaceOpWithNewOp(op, yield.getArgs(), dst); + } + + return mlir::WalkResult::advance(); + }); +} + + class CIRCopyOpLowering : public mlir::OpConversionPattern { public: using mlir::OpConversionPattern::OpConversionPattern; @@ -398,57 +427,6 @@ class CIRLoopOpLowering : public mlir::OpConversionPattern { return mlir::success(); } - void makeYieldIf(mlir::cir::YieldOpKind kind, mlir::cir::YieldOp &op, - mlir::Block *to, - mlir::ConversionPatternRewriter &rewriter) const { - if (op.getKind() == kind) { - rewriter.setInsertionPoint(op); - rewriter.replaceOpWithNewOp(op, op.getArgs(), to); - } - } - - void - lowerNestedBreakContinue(mlir::Region &loopBody, mlir::Block *exitBlock, - mlir::Block *continueBlock, - mlir::ConversionPatternRewriter &rewriter) const { - // top-level yields are lowered in matchAndRewrite - auto isNested = [&](mlir::Operation *op) { - return op->getParentRegion() != &loopBody; - }; - - auto processBreak = [&](mlir::Operation *op) { - if (!isNested(op)) - return mlir::WalkResult::advance(); - - if (isa( - *op)) // don't process breaks in nested loops and switches - return mlir::WalkResult::skip(); - - if (auto yield = dyn_cast(*op)) - makeYieldIf(mlir::cir::YieldOpKind::Break, yield, exitBlock, rewriter); - - return mlir::WalkResult::advance(); - }; - - auto processContinue = [&](mlir::Operation *op) { - if (!isNested(op)) - return mlir::WalkResult::advance(); - - if (isa( - *op)) // don't process continues in nested loops - return mlir::WalkResult::skip(); - - if (auto yield = dyn_cast(*op)) - makeYieldIf(mlir::cir::YieldOpKind::Continue, yield, continueBlock, - rewriter); - - return mlir::WalkResult::advance(); - }; - - loopBody.walk(processBreak); - loopBody.walk(processContinue); - } - mlir::LogicalResult matchAndRewrite(mlir::cir::LoopOp loopOp, OpAdaptor adaptor, mlir::ConversionPatternRewriter &rewriter) const override { @@ -478,7 +456,10 @@ class CIRLoopOpLowering : public mlir::OpConversionPattern { dyn_cast(stepRegion.back().getTerminator()); auto &stepBlock = (kind == LoopKind::For ?

This PR adds one more helper for the `alloca` instruction and re-use the existing ones. The reason is the following: right now there are two possible ways to insert alloca: either to a function entry block or to the given block after all the existing alloca instructions. But for VLA support we need to insert alloca anywhere, right after an array's size becomes known. Thus, we add one more parameter with the default value - insertion point. Also, we don't want copy-paste the code, and reuse the existing helpers, but it may be a little bit confusing to read. --- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 47 ++++++++++++++++---------- clang/lib/CIR/CodeGen/CIRGenFunction.h | 19 ++++++++--- 2 files changed, 44 insertions(+), 22 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index 368ecac5f0ed..0e3d05766ad4 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -2286,17 +2286,19 @@ mlir::Value CIRGenFunction::buildOpOnBoolExpr(const Expr *cond, mlir::Value CIRGenFunction::buildAlloca(StringRef name, mlir::Type ty, mlir::Location loc, CharUnits alignment, - bool insertIntoFnEntryBlock) { + bool insertIntoFnEntryBlock, + mlir::Value arraySize) { mlir::Block *entryBlock = insertIntoFnEntryBlock ? getCurFunctionEntryBlock() : currLexScope->getEntryBlock(); return buildAlloca(name, ty, loc, alignment, - builder.getBestAllocaInsertPoint(entryBlock)); + builder.getBestAllocaInsertPoint(entryBlock), arraySize); } mlir::Value CIRGenFunction::buildAlloca(StringRef name, mlir::Type ty, mlir::Location loc, CharUnits alignment, - mlir::OpBuilder::InsertPoint ip) { + mlir::OpBuilder::InsertPoint ip, + mlir::Value arraySize) { auto localVarPtrTy = mlir::cir::PointerType::get(builder.getContext(), ty); auto alignIntAttr = CGM.getSize(alignment); @@ -2306,7 +2308,7 @@ mlir::Value CIRGenFunction::buildAlloca(StringRef name, mlir::Type ty, builder.restoreInsertionPoint(ip); addr = builder.create(loc, /*addr type*/ localVarPtrTy, /*var type*/ ty, name, - alignIntAttr); + alignIntAttr, arraySize); if (currVarDecl) { auto alloca = cast(addr.getDefiningOp()); alloca.setAstAttr(ASTVarDeclAttr::get(builder.getContext(), currVarDecl)); @@ -2317,9 +2319,10 @@ mlir::Value CIRGenFunction::buildAlloca(StringRef name, mlir::Type ty, mlir::Value CIRGenFunction::buildAlloca(StringRef name, QualType ty, mlir::Location loc, CharUnits alignment, - bool insertIntoFnEntryBlock) { + bool insertIntoFnEntryBlock, + mlir::Value arraySize) { return buildAlloca(name, getCIRType(ty), loc, alignment, - insertIntoFnEntryBlock); + insertIntoFnEntryBlock, arraySize); } mlir::Value CIRGenFunction::buildLoadOfScalar(LValue lvalue, @@ -2465,12 +2468,11 @@ Address CIRGenFunction::CreateMemTemp(QualType Ty, CharUnits Align, /// This creates a alloca and inserts it into the entry block of the /// current region. -Address CIRGenFunction::CreateTempAllocaWithoutCast(mlir::Type Ty, - CharUnits Align, - mlir::Location Loc, - const Twine &Name, - mlir::Value ArraySize) { - auto Alloca = CreateTempAlloca(Ty, Loc, Name, ArraySize); +Address CIRGenFunction::CreateTempAllocaWithoutCast( + mlir::Type Ty, CharUnits Align, mlir::Location Loc, const Twine &Name, + mlir::Value ArraySize, mlir::OpBuilder::InsertPoint ip) { + auto Alloca = ip.isSet() ?

There are two approaches to lower `cir.ternary` imo: 1. Use `scf.if` op. 2. Use `cf.cond_br` op. I choose `scf.if` because `scf.if` + canonicalization produces `arith.select` whereas `cf.cond_br` requires scf lifting. In many ways `scf.if` is more high-level and closer to `cir.ternary`. A separate `cir.yield` lowering is required since we cannot directly replace `cir.yield` in the ternary op lowering -- the yield operands may still be illegal and doing so produces `builtin.unrealized_cast` ops. I couldn't figured out a way to solve this issue without adding a separate lowering pattern. Please let me know if you know a way to solve this issue. --- .../Lowering/ThroughMLIR/LowerCIRToMLIR.cpp | 57 ++++++++++++++++++- .../test/CIR/Lowering/ThroughMLIR/tenary.cir | 44 ++++++++++++++ 2 files changed, 98 insertions(+), 3 deletions(-) create mode 100644 clang/test/CIR/Lowering/ThroughMLIR/tenary.cir diff --git a/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRToMLIR.cpp b/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRToMLIR.cpp index 8471230c6eab..0853eeb87782 100644 --- a/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRToMLIR.cpp +++ b/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRToMLIR.cpp @@ -39,6 +39,7 @@ #include "clang/CIR/Dialect/IR/CIRTypes.h" #include "clang/CIR/Passes.h" #include "llvm/ADT/Sequence.h" +#include "llvm/ADT/TypeSwitch.h" using namespace cir;

It takes a single boolean operand which, if true, executes the body region, otherwise exits the loop. This also simplifies lowering and the dialect it self. A new constraint is now enforced on `cir.loops`: the condition region must terminate with a `cir.condition` operation. A few tests were removed as they became redundant, and others where simplified. The merge-cleanups pass no longer simplifies compile-time constant conditions, as the condition body terminator is no longer allowed to be terminated with a `cir.yield`. To circumvent this, a proper folder should be implemented to fold constant conditions, but this was left as future work.

statement was handled, returns the ReturnExpr of the statement if there is one. It also adds some extra bookkeeping to ensure that the result is returned when needed. This allows for better support of GCC's `ExprStmt` extension. The logical result was not used: it was handled but it would never fail. Any errors within builders should likely be handled with asserts and unreachables since they imply a programmer's error in the code. ghstack-source-id: 2319cf3f12e56374a52aaafa4304e74de3ee6453 Pull Request resolved: https://github.com/llvm/clangir/pull/313 --- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 3 ++- clang/lib/CIR/CodeGen/CIRGenFunction.h | 10 ++++--- clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 33 +++++++++++------------- 3 files changed, 23 insertions(+), 23 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenFunction.cpp b/clang/lib/CIR/CodeGen/CIRGenFunction.cpp index 696c6c877dd9..a3c6b8da87d1 100644 --- a/clang/lib/CIR/CodeGen/CIRGenFunction.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenFunction.cpp @@ -24,6 +24,7 @@ #include "clang/Frontend/FrontendDiagnostic.h" #include "mlir/Dialect/Func/IR/FuncOps.h" +#include "mlir/Support/LogicalResult.h" using namespace cir; using namespace clang; @@ -1114,7 +1115,7 @@ mlir::LogicalResult CIRGenFunction::buildFunctionBody(const clang::Stmt *Body) { auto result = mlir::LogicalResult::success(); if (const CompoundStmt *S = dyn_cast(Body)) - result = buildCompoundStmtWithoutScope(*S); + buildCompoundStmtWithoutScope(*S); else result = buildStmt(Body, /*useCurrentScope*/ true); diff --git a/clang/lib/CIR/CodeGen/CIRGenFunction.h b/clang/lib/CIR/CodeGen/CIRGenFunction.h index 9e2d1687366f..2d56b33dc823 100644 --- a/clang/lib/CIR/CodeGen/CIRGenFunction.h +++ b/clang/lib/CIR/CodeGen/CIRGenFunction.h @@ -834,11 +834,13 @@ class CIRGenFunction : public CIRGenTypeCache { bool IsFnTryBlock = false); void exitCXXTryStmt(const CXXTryStmt &S, bool IsFnTryBlock = false); - mlir::LogicalResult buildCompoundStmt(const clang::CompoundStmt &S); - - mlir::LogicalResult - buildCompoundStmtWithoutScope(const clang::CompoundStmt &S); + Address buildCompoundStmt(const clang::CompoundStmt &S, bool getLast = false, + AggValueSlot slot = AggValueSlot::ignored()); + Address + buildCompoundStmtWithoutScope(const clang::CompoundStmt &S, + bool getLast = false, + AggValueSlot slot = AggValueSlot::ignored()); GlobalDecl CurSEHParent; bool currentFunctionUsesSEHTry() const { return !!CurSEHParent; } diff --git a/clang/lib/CIR/CodeGen/CIRGenStmt.cpp b/clang/lib/CIR/CodeGen/CIRGenStmt.cpp index cedcdac48621..f683f7509876 100644 --- a/clang/lib/CIR/CodeGen/CIRGenStmt.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenStmt.cpp @@ -10,30 +10,27 @@ // //===----------------------------------------------------------------------===// +#include "Address.h" #include "CIRGenFunction.h" +#include "mlir/IR/Value.h" using namespace cir; using namespace clang; using namespace mlir::cir; -mlir::LogicalResult -CIRGenFunction::buildCompoundStmtWithoutScope(const CompoundStmt &S) { +Address CIRGenFunction::buildCompoundStmtWithoutScope(const CompoundStmt &S, + bool getLast, + AggValueSlot slot) { for (auto *CurStmt : S.body()) if (buildStmt(CurStmt, /*useCurrentScope=*/false).failed()) - return mlir::failure(); + return Address::invalid(); - return mlir::success(); + return Address::invalid(); } -mlir::LogicalResult CIRGenFunction::buildCompoundStmt(const CompoundStmt &S) { - mlir::LogicalResult res = mlir::success(); - - auto compoundStmtBuilder = [&]() -> mlir::LogicalResult { - if (buildCompoundStmtWithoutScope(S).failed()) - return mlir::failure(); - - return mlir::success(); - }; +Address CIRGenFunction::buildCompoundStmt(const CompoundStmt &S, bool getLast, + AggValueSlot slot) { + Address retAlloca = Address::invalid(); // Add local scope to track new declared variables.

Sorry, maybe it looks too big on the first glance. And it's kind of hard to extract something well-grained from the code and introduce it as a separate PR, but I try. Actually there is nothing really interesting done here, and the next will (I hope :) ) simplify your review process. 1) In this PR we introduce operand's constraints and the task is to collect them (and maybe transform a little) 2) There are two big functions copy-pasted from the traditional `Codegen` and I doubt they need to be reviewed. 3) We still don't do anything CIR-specific. Basically, we just work with strings in the same way like traditional `Codegen` does. 4) We just iterate over the input and output operands and collect the constraints 5) We still follow to the traditional `CodeGen` and don't do anything new, except a separate function that collects constraints infos in the very beginning of the `buildStmt`. Also, I renamed `AsmDialect` to `AsmFlavor` as you asked in #326 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 65 +++--- clang/lib/CIR/CodeGen/CIRAsm.cpp | 228 ++++++++++++++++++- clang/test/CIR/CodeGen/asm.c | 24 +- 3 files changed, 280 insertions(+), 37 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 1a9da26b49ed..fd6cc34ef6d0 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2621,29 +2621,11 @@ def StackRestoreOp : CIR_Op<"stack_restore"> { let assemblyFormat = "$ptr attr-dict `:` qualified(type($ptr))"; } -//===----------------------------------------------------------------------===// -// Operations Lowered Directly to LLVM IR -// -// These operations are hacks to get around missing features in LLVM's dialect. -// Use it sparingly and remove it once the features are added. -//===----------------------------------------------------------------------===// - -def ZeroInitConstOp : CIR_Op<"llvmir.zeroinit", [Pure]>, - Results<(outs AnyType:$result)> { - let summary = "Zero initializes a constant value of a given type"; - let description = [{ - This operation circumvents the lack of a zeroinitializer operation in LLVM - Dialect.

If a `cir.const` operation produces an integral constant from a `#cir.int` attribute, the integer's type is not verified: ```mlir %1 = cir.const(#cir.int<0> : !cir.int) : !cir.int // Not verified: !cir.int differs from !cir.int ``` The corresponding test is also wrong but fail to be detected.

Create new operation `cir.vec.insert`, which changes one element of an existing vector object and returns the modified vector object. The input and output vectors are prvalues; this operation does not touch memory. The assembly format and the order of the arguments match that of llvm.insertelement in the LLVM dialect, since the operations have identical semantics. Implement vector element lvalues in class `LValue`, adding member functions `getVectorAddress()`, `getVectorPointer()`, `getVectorIdx()`, and `MakeVectorElt(...)`. The assembly format for operation `cir.vec.extract` was changed to match that of llvm.extractelement in the LLVM dialect, since the operations have identical semantics. These two features, `cir.vec.insert` and vector element lvalues, are used to implement `v[n] = e`, where `v` is a vector. This is a little tricky, because `v[n]` isn't really an lvalue, as its address cannot be taken. The only place it can be used as an lvalue is on the left-hand side of an assignment. Implement unary operators on vector objects (except for logical not on a vector mask, which will be covered in a future commit for boolean vectors). The code for lowering cir.unary for all types, in `CIRUnaryOpLowering::matchAndRewrite`, was largely rewritten. Support for unary `+` on non-vector pointer types was added. (It was already supported and tested in AST->ClangIR CodeGen, but was missing from ClangIR->LLVM Dialect lowering.) Add tests for all binary vector arithmetic operations other than relational operators and shift operators. There were all working after the previous vector types commit, but only addition had beet tested at the time.

This simplifies mostly lowering and verifications related to `continue` statements, as well as the definition and lowering of the `cir.yield` operation. A few checks regarding region terminators were also removed from the lowering stage, since they are already enforced by MLIR. ghstack-source-id: 1810a48ada88fe7ef5638b0758a2298d9cfbdb8b Pull Request resolved: https://github.com/llvm/clangir/pull/394 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 31 +++++---- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 5 ++ clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 7 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 25 +++---- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 66 ++++++++++++++----- clang/test/CIR/CodeGen/loop.cpp | 2 +- clang/test/CIR/IR/invalid.cir | 2 +- clang/test/CIR/IR/loop.cir | 4 +- .../test/CIR/Lowering/loops-with-continue.cir | 8 +-- 9 files changed, 89 insertions(+), 61 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 49c2bce154a8..dfcfdfdb3c64 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -607,13 +607,12 @@ def ConditionOp : CIR_Op<"condition", [ def YieldOpKind_BK : I32EnumAttrCase<"Break", 1, "break">; def YieldOpKind_FT : I32EnumAttrCase<"Fallthrough", 2, "fallthrough">; -def YieldOpKind_CE : I32EnumAttrCase<"Continue", 3, "continue">; def YieldOpKind_NS : I32EnumAttrCase<"NoSuspend", 4, "nosuspend">; def YieldOpKind : I32EnumAttr< "YieldOpKind", "yield kind", - [YieldOpKind_BK, YieldOpKind_FT, YieldOpKind_CE, YieldOpKind_NS]> { + [YieldOpKind_BK, YieldOpKind_FT, YieldOpKind_NS]> { let cppNamespace = "::mlir::cir"; } @@ -634,8 +633,6 @@ def YieldOp : CIR_Op<"yield", [ReturnLike, Terminator, cannot be used if not dominated by these parent operations. - `fallthrough`: execution falls to the next region in `cir.switch` case list.

This simplifies the `cir.await` while also simplifying the `cir.yield`. If `cir.condition` holds a true value, then the `cir.await` will continue the coroutine, otherwise, it will suspend its execution. The `cir.condition` op was also updated to allow `cir.await` as its parent operation. ghstack-source-id: 1ebeb2cfbdeff6f289936d16354cba534e093ea7 Pull Request resolved: https://github.com/llvm/clangir/pull/396 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 50 +++++++++------- clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 24 +------- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 57 ++++++++----------- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 2 - clang/test/CIR/CodeGen/coro-task.cpp | 5 +- clang/test/CIR/IR/await.cir | 22 +++++++ clang/test/CIR/IR/invalid.cir | 19 +------ 7 files changed, 80 insertions(+), 99 deletions(-) create mode 100644 clang/test/CIR/IR/await.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 3276255ea09e..32498c8885aa 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -593,12 +593,38 @@ def ConditionOp : CIR_Op<"condition", [ ]> { let summary = "Loop continuation condition."; let description = [{ - The `cir.condition` termintes loop's conditional regions.

Early lowering here would complicate CIR generated code and make it harder to analyse. Further CIR to CIR passes will properly expand this at some point prior to LLVM lowering. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 14 +--- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 88 -------------------- clang/test/CIR/IR/exceptions.cir | 7 +- 3 files changed, 5 insertions(+), 104 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 3eb36e91a2cf..181135f6fc6a 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2018,15 +2018,11 @@ def CallOp : CIR_CallOp<"call"> { // TryCallOp //===----------------------------------------------------------------------===// -def TryCallOp : CIR_CallOp<"try_call", - [AttrSizedOperandSegments, DeclareOpInterfaceMethods, - Terminator]> { +def TryCallOp : CIR_CallOp<"try_call"> { let summary = "try call operation"; let description = [{ Works very similar to `cir.call` but passes down an exception object - in case anything is thrown by the callee.

Vinicius Couto Espindola Date: Mon, 22 Jan 2024 17:21:02 -0300 Subject: [PATCH 1360/2301] [CIR][IR] Refactor while loops Creates a separate C/C++ operation for while loops, while keeping the LoopOpInterface to generically handle loops. This simplifies the IR generation and printing/parsing of while loops. ghstack-source-id: 29a6d7530263a4f96dbe6ce3052875831126005d Pull Request resolved: https://github.com/llvm/clangir/pull/408 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 40 ++++++-- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 8 ++ clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 13 +-- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 8 ++ clang/test/CIR/CodeGen/loop.cpp | 30 ++---- clang/test/CIR/IR/invalid.cir | 6 +- clang/test/CIR/IR/loop.cir | 94 ------------------- clang/test/CIR/IR/while.cir | 18 ++++ clang/test/CIR/Lowering/loop.cir | 12 +-- clang/test/CIR/Lowering/loops-with-break.cir | 6 +- .../test/CIR/Lowering/loops-with-continue.cir | 6 +- 11 files changed, 91 insertions(+), 150 deletions(-) create mode 100644 clang/test/CIR/IR/while.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 89dfaaa9ce3d..e5ea6406d6a4 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -442,7 +442,7 @@ def StoreOp : CIR_Op<"store", [ def ReturnOp : CIR_Op<"return", [ParentOneOf<["FuncOp", "ScopeOp", "IfOp", "SwitchOp", "DoWhileOp", - "LoopOp"]>, + "WhileOp", "LoopOp"]>, Terminator]> { let summary = "Return from function"; let description = [{ @@ -635,7 +635,7 @@ def ConditionOp : CIR_Op<"condition", [ //===----------------------------------------------------------------------===// def YieldOp : CIR_Op<"yield", [ReturnLike, Terminator, - ParentOneOf<["IfOp", "ScopeOp", "SwitchOp", "LoopOp", "AwaitOp", + ParentOneOf<["IfOp", "ScopeOp", "SwitchOp", "WhileOp", "LoopOp", "AwaitOp", "TernaryOp", "GlobalOp", "DoWhileOp"]>]> { let summary = "Represents the default branching behaviour of a region"; let description = [{ @@ -1164,12 +1164,11 @@ def BrCondOp : CIR_Op<"brcond", //===----------------------------------------------------------------------===// def LoopOpKind_For : I32EnumAttrCase<"For", 1, "for">; -def LoopOpKind_While : I32EnumAttrCase<"While", 2, "while">; def LoopOpKind : I32EnumAttr< "LoopOpKind", "Loop kind", - [LoopOpKind_For, LoopOpKind_While]> { + [LoopOpKind_For]> { let cppNamespace = "::mlir::cir"; } @@ -1251,8 +1250,8 @@ def LoopOp : CIR_Op<"loop", switch(getKind()) { case LoopOpKind::For: return llvm::SmallVector{&getCond(), &getBody(), &getStep()}; - case LoopOpKind::While: - return llvm::SmallVector{&getCond(), &getBody()}; + // case LoopOpKind::While: + // return llvm::SmallVector{&getCond(), &getBody()}; // case LoopOpKind::DoWhile: // return llvm::SmallVector{&getBody(), &getCond()}; } @@ -1261,7 +1260,7 @@ def LoopOp : CIR_Op<"loop", } //===----------------------------------------------------------------------===// -// DoWhileOp +// While & DoWhileOp //===----------------------------------------------------------------------===// class WhileOpBase : CIR_Op : CIR_Op { + let regions = (region SizedRegion<1>:$cond, MinSizedRegion<1>:$body); + let assemblyFormat = "$cond `do` $body attr-dict"; + + let description = [{ + Represents a C/C++ while loop.

The new representation removes some bloat and places the regions in order of execution. ghstack-source-id: 886e0dacc632e5809015e2212810d690ef3ec294 Pull Request resolved: https://github.com/llvm/clangir/pull/409 --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 173 +++++++----------- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 9 + clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 16 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 44 +---- .../lib/CIR/Interfaces/CIRLoopOpInterface.cpp | 2 + .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 1 - clang/test/CIR/CodeGen/loop-scope.cpp | 6 +- clang/test/CIR/CodeGen/loop.cpp | 16 +- clang/test/CIR/CodeGen/rangefor.cpp | 10 +- clang/test/CIR/IR/for.cir | 22 +++ clang/test/CIR/IR/invalid.cir | 13 ++ clang/test/CIR/IR/loop.cir | 63 ------- clang/test/CIR/Lowering/dot.cir | 14 +- clang/test/CIR/Lowering/loop.cir | 14 +- clang/test/CIR/Lowering/loops-with-break.cir | 42 ++--- .../test/CIR/Lowering/loops-with-continue.cir | 42 ++--- 16 files changed, 204 insertions(+), 283 deletions(-) create mode 100644 clang/test/CIR/IR/for.cir delete mode 100644 clang/test/CIR/IR/loop.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index e5ea6406d6a4..cf4f103e3b6e 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -442,7 +442,7 @@ def StoreOp : CIR_Op<"store", [ def ReturnOp : CIR_Op<"return", [ParentOneOf<["FuncOp", "ScopeOp", "IfOp", "SwitchOp", "DoWhileOp", - "WhileOp", "LoopOp"]>, + "WhileOp", "ForOp"]>, Terminator]> { let summary = "Return from function"; let description = [{ @@ -635,7 +635,7 @@ def ConditionOp : CIR_Op<"condition", [ //===----------------------------------------------------------------------===// def YieldOp : CIR_Op<"yield", [ReturnLike, Terminator, - ParentOneOf<["IfOp", "ScopeOp", "SwitchOp", "WhileOp", "LoopOp", "AwaitOp", + ParentOneOf<["IfOp", "ScopeOp", "SwitchOp", "WhileOp", "ForOp", "AwaitOp", "TernaryOp", "GlobalOp", "DoWhileOp"]>]> { let summary = "Represents the default branching behaviour of a region"; let description = [{ @@ -1159,106 +1159,6 @@ def BrCondOp : CIR_Op<"brcond", }]; } -//===----------------------------------------------------------------------===// -// LoopOp -//===----------------------------------------------------------------------===// - -def LoopOpKind_For : I32EnumAttrCase<"For", 1, "for">; - -def LoopOpKind : I32EnumAttr< - "LoopOpKind", - "Loop kind", - [LoopOpKind_For]> { - let cppNamespace = "::mlir::cir"; -} - -def LoopOp : CIR_Op<"loop", - [LoopOpInterface, - DeclareOpInterfaceMethods, - DeclareOpInterfaceMethods, - RecursivelySpeculatable, NoRegionArguments]> { - let summary = "Loop"; - let description = [{ - `cir.loop` represents C/C++ loop forms.

[PATCH 1362/2301] [CIR][CIRGen][Exceptions] Populate catch clauses and fix order of operations More machinery for exceptions. This time around we finally emit a cir.catch and fix the order of emitting operations. This allows a testcase to be added. I also added `CatchParamOp`, which fetches the arguments for the clauses from the !cir.eh_info object.

Create new operation `cir.vec.cmp` which implements the relational comparison operators (`== != < > <= >=`) on vector types. A new operation was created rather than reusing `cir.cmp` because the result is a vector of a signed intergral type, not a `bool`. Add CodeGen and Lowering tests for vector comparisons. Fix the floating-point comparison predicate when lowering to LLVM. To handle NaN values correctly, the comparisons need to be ordered rather than unordered. (Except for `!=`, which needs to be unordered.) For example, "ueq" was changed to "oeq". --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 25 ++++ clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 63 ++++---- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 137 +++++++++++------- clang/test/CIR/CodeGen/vectype.cpp | 29 ++++ clang/test/CIR/Lowering/cmp.cir | 10 +- clang/test/CIR/Lowering/vectype.cpp | 79 +++++++++- 6 files changed, 258 insertions(+), 85 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index dc0140550382..1e5145d0e15b 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -1846,6 +1846,31 @@ def VecCreateOp : CIR_Op<"vec.create", [Pure]> { let hasVerifier = 1; } +//===----------------------------------------------------------------------===// +// VecCmp +//===----------------------------------------------------------------------===// + +def VecCmpOp : CIR_Op<"vec.cmp", [Pure, SameTypeOperands]> { + + let summary = "Compare two vectors"; + let description = [{ + The `cir.vec.cmp` operation does an element-wise comparison of two vectors + of the same type.

The original `CodeGen` does the following: once a constant array contain trailing zeros, a struct with two members is generated: initialized elements and `zeroinitializer` for the remaining part. And depending on some conditions, `memset` or `memcpy` are emitted. In the latter case a global const array is created. Well, we may go this way, but it requires us to implement [features](https://github.com/llvm/clangir/blob/main/clang/lib/CIR/CodeGen/CIRGenDecl.cpp#L182) that are not implemented yet. Another option is to add one more parameter to the `constArrayAttr` and utilize it during the lowering. So far I chose this way, but if you have any doubts, we can discuss here. So we just emit constant array as usually and once there are trailing zeros, lower this arrray (i.e. an attribute) as a value. I added a couple of tests and will add more, once we agree on the approach. So far I marked the PR as a draft one. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 16 +++++++++-- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 10 ++++++- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 25 ++++++++++++++--- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 28 +++++++++++++++++-- clang/test/CIR/CodeGen/const-array.c | 10 +++++++ clang/test/CIR/Lowering/const.cir | 13 +++++++++ 6 files changed, 92 insertions(+), 10 deletions(-) create mode 100644 clang/test/CIR/CodeGen/const-array.c diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index b9fe93b98de6..4ad2b4fbbe9a 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -116,14 +116,22 @@ def ConstArrayAttr : CIR_Attr<"ConstArray", "const_array", [TypedAttrInterface]> }]; let parameters = (ins AttributeSelfTypeParameter<"">:$type, - "Attribute":$elts); + "Attribute":$elts, + "int":$trailingZerosNum); // Define a custom builder for the type; that removes the need to pass // in an MLIRContext instance, as it can be infered from the `type`. let builders = [ AttrBuilderWithInferredContext<(ins "mlir::cir::ArrayType":$type, "Attribute":$elts), [{ - return $_get(type.getContext(), type, elts); + int zeros = 0; + auto typeSize = type.cast().getSize(); + if (auto str = elts.dyn_cast()) + zeros = typeSize - str.size(); + else + zeros = typeSize - elts.cast().size(); + + return $_get(type.getContext(), type, elts, zeros); }]> ]; @@ -132,6 +140,10 @@ def ConstArrayAttr : CIR_Attr<"ConstArray", "const_array", [TypedAttrInterface]> // Enable verifier. let genVerifyDecl = 1; + + let extraClassDeclaration = [{ + bool hasTrailingZeros() const { return getTrailingZerosNum() != 0; }; + }]; } //===----------------------------------------------------------------------===// diff --git a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp index 2fb84275751c..0241c7b3d5a9 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp @@ -959,10 +959,18 @@ buildArrayConstant(CIRGenModule &CGM, mlir::Type DesiredType, // Add a zeroinitializer array filler if we have lots of trailing zeroes. unsigned TrailingZeroes = ArrayBound - NonzeroLength; if (TrailingZeroes >= 8) { - assert(0 && "NYE"); assert(Elements.size() >= NonzeroLength && "missing initializer for non-zero element"); + SmallVector Eles; + Eles.reserve(Elements.size()); + for (auto const &Element : Elements) + Eles.push_back(Element); + + return builder.getConstArray( + mlir::ArrayAttr::get(builder.getContext(), Eles), + mlir::cir::ArrayType::get(builder.getContext(), CommonElementType, + ArrayBound)); // TODO(cir): If all the elements had the same type up to the trailing // zeroes, emit a struct of two arrays (the nonzero data and the // zeroinitializer).

Now only global structs are supported, the support of the local ones can be added more or less easily - there is one ugly thing need to be done though) So .. what is all about. First of all - as usually, I'm sorry for the big PR. But it's hard to break it down to peaces. The good news is that in the same time it's a copy-pasta from the original codegen, no surprises here. Basically, the most hard place to read is `ConstantAggregateBuilder::addBits` copied with minimum of changes. The main problem - and frankly speaking I have no idea why it's done this way in the original codegen - is that the data layout is different for such structures, I mean literally another type is used. For instance, the code: ``` struct T { int X : 15; int Y : 6; unsigned Z : 9; int W; }; struct T GV = { 1, 5, 256, -1}; ``` is represented in LLVM IR (with no CIR enabled) as: ``` %struct.T = type { i32, i32 } %struct.Inner = type { i8, i32 } @GV = dso_local global { i8, i8, i8, i8, i32 } ... ``` i.e. the global var `GV` is looks like a struct of single bytes (up to the last field, which is not a btfield). And my guess is that we want to have the same behavior in CIR. So we do. The main problem is that we have to treat the same data differently - and this is why one additional `bitcast` is needed when we create a global var. Actually, there was a comment there - and I really wonder where it came from. But anyways, I don't really like this and don't see any good workaround here. Well, maybe we may add a kind of map in order to store the correspondence between types and do a bitcast more wisely. The same is true for the const structs with bitfields defined locally. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 1 + clang/include/clang/CIR/Dialect/IR/CIRTypes.h | 2 + clang/lib/CIR/CodeGen/CIRDataLayout.h | 2 +- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 16 ++ clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 196 ++++++++++++++++-- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 7 +- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 10 + clang/test/CIR/CodeGen/const-bitfields.c | 47 +++++ 9 files changed, 271 insertions(+), 20 deletions(-) create mode 100644 clang/test/CIR/CodeGen/const-bitfields.c diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 4ad2b4fbbe9a..9fc8ce9efad0 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -209,6 +209,7 @@ def IntAttr : CIR_Attr<"Int", "int", [TypedAttrInterface]> { int64_t getSInt() const { return getValue().getSExtValue(); } uint64_t getUInt() const { return getValue().getZExtValue(); } bool isNullValue() const { return getValue() == 0; } + uint64_t getBitWidth() const { return getType().cast().getWidth(); } }]; let genVerifyDecl = 1; let hasCustomAssemblyFormat = 1; diff --git a/clang/include/clang/CIR/Dialect/IR/CIRTypes.h b/clang/include/clang/CIR/Dialect/IR/CIRTypes.h index 40a3486e12ee..46835e548a69 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRTypes.h +++ b/clang/include/clang/CIR/Dialect/IR/CIRTypes.h @@ -169,6 +169,8 @@ class StructType uint64_t getPreferredAlignment(const DataLayout &dataLayout, DataLayoutEntryListRef params) const; + bool isLayoutIdentical(const StructType &other); + // Utilities for lazily computing and cacheing data layout info. private: mutable Type largestMember{}; diff --git a/clang/lib/CIR/CodeGen/CIRDataLayout.h b/clang/lib/CIR/CodeGen/CIRDataLayout.h index b1b10ba6b6da..bc4c7762d5bc 100644 --- a/clang/lib/CIR/CodeGen/CIRDataLayout.h +++ b/clang/lib/CIR/CodeGen/CIRDataLayout.h @@ -26,7 +26,7 @@ class CIRDataLayout { mlir::DataLayout layout; CIRDataLayout(mlir::ModuleOp modOp); - bool isBigEndian() { return bigEndian; } + bool isBigEndian() const { return bigEndian; } // `useABI` is `true` if not using prefered alignment. unsigned getAlignment(mlir::Type ty, bool useABI) const { diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.h b/clang/lib/CIR/CodeGen/CIRGenBuilder.h index 3da914fcb150..e866fe50638d 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuilder.h +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.h @@ -470,6 +470,22 @@ class CIRGenBuilderTy : public CIRBaseBuilderTy { return type; } + mlir::cir::StructType + getCompleteStructType(mlir::ArrayAttr fields, bool packed = false, + llvm::StringRef name = "", + const clang::RecordDecl *ast = nullptr) { + llvm::SmallVector members; + for (auto &attr : fields) { + const auto typedAttr = attr.dyn_cast(); + members.push_back(typedAttr.getType()); + } + + if (name.empty()) + return getAnonStructTy(members, packed, ast); + else + return getCompleteStructTy(members, name, packed, ast); + } + mlir::cir::ArrayType getArrayType(mlir::Type eltType, unsigned size) { return mlir::cir::ArrayType::get(getContext(), eltType, size); } diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index d0a02508cbc1..d8327706b457 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -700,9 +700,15 @@ static LValue buildGlobalVarDeclLValue(CIRGenFunction &CGF, const Expr *E, llvm_unreachable("not implemented"); auto V = CGF.CGM.getAddrOfGlobalVar(VD); + + if (VD->getTLSKind() != VarDecl::TLS_None) + llvm_unreachable("NYI"); + auto RealVarTy = CGF.getTypes().convertTypeForMem(VD->getType()); - // TODO(cir): do we need this for CIR?

The implementation is almost the same as in original codegen. But the original codegen can reuse the value of emitted compound literal global variable in case then the init expression of new variable and this variable are the same. It's easy to implement this feature. But I can't find any test-case then this feature will be applied.

Basically, these changes handle different expressions, like `int (*a[5])[n]` or `sizeof(a[n])`. I took tests from the original `codegen` - they don't check anything, just verify we don't fail. There is still an issue with a proper cleanup - there are cases when `stack_save` doesn't dominate a corresponded `stack_restore`. For example in the next example: ``` void test(unsigned x) { while (1) { char a[x]; if (x > 5) break; ++x; } } ``` Look like `break` here doesn't lead to `stack_restore`. But I would say this is less related to VLA, though probably I need to fix this as well. --- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 37 +++++++-- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 44 +++++++++- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 7 +- clang/test/CIR/CodeGen/vla.c | 95 ++++++++++++++++++++++ 5 files changed, 174 insertions(+), 11 deletions(-) create mode 100644 clang/test/CIR/CodeGen/vla.c diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index d8327706b457..c3dac1cdf6e0 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -1208,6 +1208,9 @@ Address CIRGenFunction::buildArrayToPointerDecay(const Expr *E, Addr.getPointer().getType().dyn_cast(); assert(lvalueAddrTy && "expected pointer"); + if (E->getType()->isVariableArrayType()) + return Addr; + auto pointeeTy = lvalueAddrTy.getPointee().dyn_cast(); assert(pointeeTy && "expected array"); @@ -1215,10 +1218,6 @@ Address CIRGenFunction::buildArrayToPointerDecay(const Expr *E, assert(arrayTy.isa() && "expected array"); assert(pointeeTy == arrayTy); - // TODO(cir): in LLVM codegen VLA pointers are always decayed, so we don't - // need to do anything here.

Nothing interesting, just some copy-pasta from the `codegen` with some sort of simplifications for now. Well, I'm not sure `functional-type` is the best way to print operands though it's used in mlir's `InlineAsmOp`. But anyways, maybe you have a better idea.

As you know, we need to create a storage for bit fields that usually contain several of them. There next code fails with `IntType` size check which exceeds 64 bits. ``` typedef struct { uint8_t a; uint8_t b; uint8_t c; int d: 2; int e: 2; int f: 4; int g: 25; int h: 3; int i: 4; int j: 3; int k: 8; int l: 14; } D; void foo() { D d; } ``` Note, if we remove first three fields (or even one) everything will be fine even without this fix, because [this](https://github.com/llvm/clangir/blob/main/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp#L553) check won't pass. The bug is kind of hard to reproduce and I would say it's a rare case. I mean the problem is not only in the number of bit fields that form together something bigger than 64 bits. Well, while iterating over the bit fields in some struct type, we need to stop accumulating bit fields in one storage and start to do the same in another one. Basically, we operate with `Tail` and `StartBitOffset` where the former is an offset of the next field. And once `Tail - StartBitOffset >= 64` we say that it's not possible to create a storage of such size due to `IntType` size limitation. Sounds reasonable. But it can be a case when we can not afford to take the next field because its `Tail` in turn leads to a storage of the size bigger then 64. Thus, we want to check it as well. From the implementation point of view I added one more check to the `IsBetterAsSingleFieldRun` in order to have all these checks for size in a single place. And the check I mentioned before were saving us from hitting this issue. --- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 18 ++++++++++--- clang/test/CIR/CodeGen/bitfields.c | 25 +++++++++++++++++++ 2 files changed, 39 insertions(+), 4 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp b/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp index 62eb8d659748..48146b3caa20 100644 --- a/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp +++ b/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp @@ -500,9 +500,14 @@ void CIRRecordLowering::accumulateBitFields( // bitfield a separate storage component so as it can be accessed directly // with lower cost. auto IsBetterAsSingleFieldRun = [&](uint64_t OffsetInRecord, - uint64_t StartBitOffset) { - if (OffsetInRecord >= 64) // See IntType::verify + uint64_t StartBitOffset, + uint64_t nextTail = 0) { + if (OffsetInRecord >= 64 || + (nextTail > StartBitOffset && + nextTail - StartBitOffset >= 64)) { // See IntType::verify return true; + } + if (!cirGenTypes.getModule().getCodeGenOpts().FineGrainedBitfieldAccesses) return false; llvm_unreachable("NYI"); @@ -545,13 +550,18 @@ void CIRRecordLowering::accumulateBitFields( // field is inconsistent with the offset of previous field plus its offset, // skip the block below and go ahead to emit the storage.

LLVMIR lowering support is not included in this PR. > [!NOTE] > As a side note, C++20 adds the `` header which includes some bit operation functions with similar functionalities to the built-in functions mentioned above. However, these standard library functions have slightly different semantics than the built-in ones and this PR does not include support for these standard library functions. Support for these functions may be added later, or amended into this PR if the reviewers request so.

From: David Olsen Date: Tue, 5 Mar 2024 11:31:16 -0800 Subject: [PATCH 1431/2301] [CIR] Vector types - part 4 (#490) This is part 4 of implementing vector types and vector operations in ClangIR, issue #284. This change has three small additions. Implement a "vector splat" conversion, which converts a scalar into vector, initializing all the elements of the vector with the scalar. Implement incomplete initialization of a vector, where the number of explicit initializers is less than the number of elements in the vector. The rest of the elements are implicitly zero initialized. Implement conversions between different vector types. The language rules require that the two types be the same size (in bytes, not necessarily in the number of elements). These conversions are always implemented with a bitcast. The first two changes only required changes to the AST -> ClangIR code gen. There are no changes to the ClangIR dialect, so no changes to the LLVM lowering were needed. The third part only required a change to a validation rule. The code to implement a vector bitcast was already present. The compiler just needed to stop rejecting it as invalid ClangIR. --- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 29 +++++++++++++++++++--- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 9 ++++--- clang/test/CIR/CodeGen/vectype.cpp | 27 ++++++++++++++++++++ clang/test/CIR/IR/invalid.cir | 2 +- clang/test/CIR/Lowering/vectype.cpp | 6 +++++ 5 files changed, 65 insertions(+), 8 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp index 95844e1bb686..1af5628208da 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp @@ -1531,8 +1531,19 @@ mlir::Value ScalarExprEmitter::VisitCastExpr(CastExpr *CE) { } case CK_MatrixCast: llvm_unreachable("NYI"); - case CK_VectorSplat: - llvm_unreachable("NYI"); + case CK_VectorSplat: { + // Create a vector object and fill all elements with the same scalar value. + assert(DestTy->isVectorType() && "CK_VectorSplat to non-vector type"); + mlir::Value Value = Visit(E); + SmallVector Elements; + auto VecType = CGF.getCIRType(DestTy).dyn_cast(); + auto NumElements = VecType.getSize(); + for (uint64_t Index = 0; Index < NumElements; ++Index) { + Elements.push_back(Value); + } + return CGF.getBuilder().create( + CGF.getLoc(E->getSourceRange()), VecType, Elements); + } case CK_FixedPointCast: llvm_unreachable("NYI"); case CK_FixedPointToBoolean: @@ -1660,13 +1671,23 @@ mlir::Value ScalarExprEmitter::VisitInitListExpr(InitListExpr *E) { assert(!UnimplementedFeature::scalableVectors() && "NYI: scalable vector init"); assert(!UnimplementedFeature::vectorConstants() && "NYI: vector constants"); + auto VectorType = + CGF.getCIRType(E->getType()).dyn_cast(); SmallVector Elements; for (Expr *init : E->inits()) { Elements.push_back(Visit(init)); } + // Zero-initialize any remaining values. + if (NumInitElements < VectorType.getSize()) { + mlir::Value ZeroValue = CGF.getBuilder().create( + CGF.getLoc(E->getSourceRange()), VectorType.getEltType(), + CGF.getBuilder().getZeroInitAttr(VectorType.getEltType())); + for (uint64_t i = NumInitElements; i < VectorType.getSize(); ++i) { + Elements.push_back(ZeroValue); + } + } return CGF.getBuilder().create( - CGF.getLoc(E->getSourceRange()), CGF.getCIRType(E->getType()), - Elements); + CGF.getLoc(E->getSourceRange()), VectorType, Elements); } if (NumInitElements == 0) { diff --git a/clang/lib/CIR/Dialect/IR/CIRDialect.cpp b/clang/lib/CIR/Dialect/IR/CIRDialect.cpp index 1f51087b472e..8abf57dd942e 100644 --- a/clang/lib/CIR/Dialect/IR/CIRDialect.cpp +++ b/clang/lib/CIR/Dialect/IR/CIRDialect.cpp @@ -428,9 +428,12 @@ LogicalResult CastOp::verify() { return success(); } case cir::CastKind::bitcast: { - if (!srcType.dyn_cast() || - !resType.dyn_cast()) - return emitOpError() << "requires !cir.ptr type for source and result"; + if ((!srcType.isa() || + !resType.isa()) && + (!srcType.isa() || + !resType.isa())) + return emitOpError() + << "requires !cir.ptr or !cir.vector type for source and result"; return success(); } case cir::CastKind::floating: { diff --git a/clang/test/CIR/CodeGen/vectype.cpp b/clang/test/CIR/CodeGen/vectype.cpp index 8006014854c3..6824fd5ac4fa 100644 --- a/clang/test/CIR/CodeGen/vectype.cpp +++ b/clang/test/CIR/CodeGen/vectype.cpp @@ -16,6 +16,22 @@ void vector_int_test(int x) { vi4 b = { x, 5, 6, x + 1 }; // CHECK: %{{[0-9]+}} = cir.vec.create(%{{[0-9]+}}, %{{[0-9]+}}, %{{[0-9]+}}, %{{[0-9]+}} : !s32i, !s32i, !s32i, !s32i) : + // Incomplete vector initialization. + vi4 bb = { x, x + 1 }; + // CHECK: %[[#zero:]] = cir.const(#cir.int<0> : !s32i) : !s32i + // CHECK: %{{[0-9]+}} = cir.vec.create(%{{[0-9]+}}, %{{[0-9]+}}, %[[#zero]], %[[#zero]] : !s32i, !s32i, !s32i, !s32i) : + + // Scalar to vector conversion, a.k.a. vector splat.

Codegen of `__builtin_expect` emits `cir.expect` opcode. Then `cir.expect` will be lowered to `llvm.expect` intrinsic. When implementing __builtin_expect I faced with minor issue. CIR lowering of `if` often emits the lllvm IR with redundant cast instructions. Like this: ``` %0 = call i64 @llvm.expect.i64(i64 %any, i64 1), !dbg !13 %1 = icmp ne i64 %0, 0 %2 = zext i1 %0 to i8 // redundant %3 = trunc i8 %1 to i1 // redundant br i1 %3, label %l1, label %l2 ``` But the llvm pass `LowerExpectIntrinsicPass` (that should replace `llvm.expect` with branch metadata) performs only simple pattern-matching.

For `cir.bit.clz`, `cir.bit.ctz`, and `cir.bit.popcount`, they can be lowered directly to LLVM intrinsic calls to `@llvm.ctlz`, `@llvm.cttz`, and `@llvm.ctpop`, respectively. For the other three bit operations, namely `cir.bit.clrsb`, `cir.bit.ffs`, and `cir.bit.parity`, they are lowered to a sequence of LLVM IR instructions that implements their functionalities.

Also, operand attributes are added and it's the last change in the `cir.asm` operation afaik. But I would wait untill the next PR, which will contain more examples and maybe will help us to get more readable format for the operation. Note, that we have to add an attribute for each operand - because the lowering of the llvm dialect to LLVM IR iterates over them in the same order. The next PR will be last one (so far) in the series of PRs dedicated to the inline assembly support. It will add storing of the results. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 11 +- clang/lib/CIR/CodeGen/Address.h | 5 + clang/lib/CIR/CodeGen/CIRAsm.cpp | 146 ++++++++++++++++-- clang/lib/CIR/CodeGen/CIRGenFunction.h | 15 +- .../CodeGen/UnimplementedFeatureGuarding.h | 6 + .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 19 +++ clang/test/CIR/CodeGen/asm.c | 12 +- clang/test/CIR/Lowering/asm.cir | 4 +- 8 files changed, 186 insertions(+), 32 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 7dab06b35cd6..8b8dbe1a2222 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -3093,6 +3093,10 @@ def CIR_InlineAsmOp : CIR_Op<"asm", [RecursiveMemoryEffects]> { - the output variable index referenced by the input operands. - the index of early-clobber operand + Operand attributes is a storage of attributes, where each element corresponds + to the operand with the same index.

Fix the assemblyFormat for all the vector operations in the ClangIR dialect so that vector types appear in ClangIR as `!cir.vector` instead of as just ``. When I first created the vector ops, I forgot to use `qualified` as necessary when writing out types. This change fixes that. There is no change in behavior, but there is a change to the text version of ClangIR, which required changing the ClangIR expected results and ClangIR inputs in the tests. 2. Create a new `cir.vec.splat` operation and use that for "vector splat", i.e. a conversion from a scalar to a vector. A "vector splat" conversion had been implemented with `cir.vec.create` before. This change results in different ClangIR and different LLVM IR, which again required updating the tests, but no noticeable change in compiler behavior. 3. Create an `IntegerVector` type constraint, which requires that the given type be a vector whose element type is an integer. It can be any integral type, and the vector can be of any size. Use the new type constraint in the definition of `cir.vec.ternary`, whose condition operand must be an `IntegerVector`. Remove the integral type check from `VecTernaryOp::verify`, since doing the check there is now redundant. The only possibly visible change is to the text of an error message when validation of `cir.vec.ternary` fails. The expected output of a validation test was updated with the new message. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 44 +++++++++++++--- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 9 ++++ clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 11 +--- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 14 ++---- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 33 +++++++++++- clang/test/CIR/CodeGen/vectype.cpp | 50 +++++++++---------- clang/test/CIR/IR/invalid.cir | 38 +++++++------- clang/test/CIR/Lowering/vectype.cpp | 7 +++ 8 files changed, 137 insertions(+), 69 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 8b8dbe1a2222..b8b8308e43ed 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2008,7 +2008,8 @@ def VecInsertOp : CIR_Op<"vec.insert", [Pure, let results = (outs CIR_VectorType:$result); let assemblyFormat = [{ - $value `,` $vec `[` $index `:` type($index) `]` attr-dict `:` type($vec) + $value `,` $vec `[` $index `:` type($index) `]` attr-dict `:` + qualified(type($vec)) }]; let hasVerifier = 0; @@ -2032,7 +2033,7 @@ def VecExtractOp : CIR_Op<"vec.extract", [Pure, let results = (outs CIR_AnyType:$result); let assemblyFormat = [{ - $vec `[` $index `:` type($index) `]` attr-dict `:` type($vec) + $vec `[` $index `:` type($index) `]` attr-dict `:` qualified(type($vec)) }]; let hasVerifier = 0; @@ -2055,12 +2056,41 @@ def VecCreateOp : CIR_Op<"vec.create", [Pure]> { let results = (outs CIR_VectorType:$result); let assemblyFormat = [{ - `(` ($elements^ `:` type($elements))? `)` `:` type($result) attr-dict + `(` ($elements^ `:` type($elements))? `)` `:` qualified(type($result)) + attr-dict }]; let hasVerifier = 1; } +//===----------------------------------------------------------------------===// +// VecSplat +//===----------------------------------------------------------------------===// + +// cir.vec.splat is a separate operation from cir.vec.create because more +// efficient LLVM IR can be generated for it, and because some optimization and +// analysis passes can benefit from knowing that all elements of the vector +// have the same value. + +def VecSplatOp : CIR_Op<"vec.splat", [Pure, + TypesMatchWith<"type of 'value' matches element type of 'result'", "result", + "value", "$_self.cast().getEltType()">]> { + + let summary = "Convert a scalar into a vector"; + let description = [{ + The `cir.vec.splat` operation creates a vector value from a scalar value. + All elements of the vector have the same value, that of the given scalar. + }]; + + let arguments = (ins CIR_AnyType:$value); + let results = (outs CIR_VectorType:$result); + + let assemblyFormat = [{ + $value `:` type($value) `,` qualified(type($result)) attr-dict + }]; + let hasVerifier = 0; +} + //===----------------------------------------------------------------------===// // VecCmp //===----------------------------------------------------------------------===// @@ -2080,7 +2110,8 @@ def VecCmpOp : CIR_Op<"vec.cmp", [Pure, SameTypeOperands]> { let results = (outs CIR_VectorType:$result); let assemblyFormat = [{ - `(` $kind `,` $lhs `,` $rhs `)` `:` type($lhs) `,` type($result) attr-dict + `(` $kind `,` $lhs `,` $rhs `)` `:` qualified(type($lhs)) `,` + qualified(type($result)) attr-dict }]; let hasVerifier = 0; @@ -2107,11 +2138,12 @@ def VecTernaryOp : CIR_Op<"vec.ternary", The result is a vector of the same type as the second and third arguments.

Basically, the main problem for the packed structures support is an absence of arbitrary sized integers in CIR. Well, one workaround is to use `mlir::IntegerType` for that, but it's kind of wrong way (please correct me if I'm wrong). Another way is to introduce this type in CIR. So far I suggest this way: instead of arbitrary sized integers we will create an array of bytes for bitfield storages whenever they doesn't fit into the CIR `IntType`. Well, the original codegen creates storages with alignment 8 - so it can be `i24` storage type for instance. Previously, we just created storages that could be represented as CIR `IntType`: 8, 16, 32, 64. And it was working before I came up with a necessity to support packed structures. At first glance it's not a problem - just add `determinePacked` method from the original codegen and that's it. But it turned out that this method _infers_ the fact if a structure is packed or not. It doesn't use the AST attribute for that as one could think - it works with offsets and alignments of fields. Thus, we either need to invent our own way to determine packed structures (which is error prone and maybe not doable at all) or try to use the existing one. Also, we go closer to the original lllvm's data layout in this case. 1) I had to move the lowering details from the `LoweringPrepare` to the `LowerToLLVM`, because it's not possible to do a `load` from the array of bytes to the integer type - and it's ok in llvm dialect. Thus, all the math operations can be expressed without any problems. Basically the most of the diff you see is because of the changes in the lowering. The remaining part is more or less easy to read. 2) There are minor changes in `CIRRecordLayoutBuilder` - as described above, we use may generate an array of bytes as a storage. 3) Some cosmetic changes in `CIRGenExpr` - since we don't want to infer the storage type again and just use the one stored in the `CIRGenBitFieldInfo`. 4) Helpers are introduced in the lowering - but nothing hard - just shifts and logical ops. 5) I removed `bitfield-ops` test - because now the test cases covered there are all in `bitfields.c` and `bitfields.cpp` .

There are some discussion in #508 and according to the plan we do the following here: - a new pass called `cir-flatten-cfg` that is a stub now but later will be responsible for the regions inlining. The pass works only if `-emit-flat-cir` is passed in cmd line. Thus, the clang behavior is not changed here from the user's point of view. - The pass will be accomplished with `goto` solver later, so we talk about several passes that are mandatory for the lowering into `llvm` dialect. There are at least two clients of this pass that will be affected: `clang` itself and `cir-opt`, so we need a common point for them: and `populateCIRFlatteningPasses` and `populateCIRToLLVMPasses` guarantee that `CIR` will be in the correct state for all the clients, whatever new passes we will add later. --- clang/include/clang/CIR/CIRToCIRPasses.h | 15 +++-- clang/include/clang/CIR/Dialect/Passes.h | 3 + clang/include/clang/CIR/Dialect/Passes.td | 14 +++++ clang/include/clang/CIR/Passes.h | 4 ++ .../clang/CIRFrontendAction/CIRGenAction.h | 8 +++ clang/include/clang/Driver/Options.td | 2 + clang/include/clang/Driver/Types.def | 1 + .../include/clang/Frontend/FrontendOptions.h | 3 + clang/lib/CIR/CodeGen/CIRPasses.cpp | 26 ++++++-- .../lib/CIR/Dialect/Transforms/CMakeLists.txt | 1 + .../lib/CIR/Dialect/Transforms/FlattenCFG.cpp | 60 +++++++++++++++++++ clang/lib/CIR/FrontendAction/CIRGenAction.cpp | 10 +++- .../CIR/Lowering/DirectToLLVM/CMakeLists.txt | 1 + .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 13 +++- clang/lib/Driver/Driver.cpp | 4 ++ clang/lib/Driver/ToolChains/Clang.cpp | 6 +- clang/lib/Frontend/CompilerInvocation.cpp | 5 +- .../ExecuteCompilerInvocation.cpp | 5 +- clang/test/CIR/mlirprint.c | 14 ++++- clang/tools/cir-opt/cir-opt.cpp | 8 ++- 20 files changed, 180 insertions(+), 23 deletions(-) create mode 100644 clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp diff --git a/clang/include/clang/CIR/CIRToCIRPasses.h b/clang/include/clang/CIR/CIRToCIRPasses.h index 162846c75184..ed089cd966f4 100644 --- a/clang/include/clang/CIR/CIRToCIRPasses.h +++ b/clang/include/clang/CIR/CIRToCIRPasses.h @@ -28,12 +28,15 @@ class ModuleOp; namespace cir { // Run set of cleanup/prepare/etc passes CIR <-> CIR. -mlir::LogicalResult runCIRToCIRPasses( - mlir::ModuleOp theModule, mlir::MLIRContext *mlirCtx, - clang::ASTContext &astCtx, bool enableVerifier, bool enableLifetime, - llvm::StringRef lifetimeOpts, bool enableIdiomRecognizer, - llvm::StringRef idiomRecognizerOpts, bool enableLibOpt, - llvm::StringRef libOptOpts, std::string &passOptParsingFailure); +mlir::LogicalResult +runCIRToCIRPasses(mlir::ModuleOp theModule, mlir::MLIRContext *mlirCtx, + clang::ASTContext &astCtx, bool enableVerifier, + bool enableLifetime, llvm::StringRef lifetimeOpts, + bool enableIdiomRecognizer, + llvm::StringRef idiomRecognizerOpts, bool enableLibOpt, + llvm::StringRef libOptOpts, + std::string &passOptParsingFailure, bool flattenCIR); + } // namespace cir #endif // CLANG_CIR_CIRTOCIRPASSES_H_ diff --git a/clang/include/clang/CIR/Dialect/Passes.h b/clang/include/clang/CIR/Dialect/Passes.h index a685ab8ce3fa..2f713240944f 100644 --- a/clang/include/clang/CIR/Dialect/Passes.h +++ b/clang/include/clang/CIR/Dialect/Passes.h @@ -34,6 +34,9 @@ std::unique_ptr createIdiomRecognizerPass(); std::unique_ptr createIdiomRecognizerPass(clang::ASTContext *astCtx); std::unique_ptr createLibOptPass(); std::unique_ptr createLibOptPass(clang::ASTContext *astCtx); +std::unique_ptr createFlattenCFGPass(); + +void populateCIRPreLoweringPasses(mlir::OpPassManager &pm); //===----------------------------------------------------------------------===// // Registration diff --git a/clang/include/clang/CIR/Dialect/Passes.td b/clang/include/clang/CIR/Dialect/Passes.td index affc28b85003..e63b97469980 100644 --- a/clang/include/clang/CIR/Dialect/Passes.td +++ b/clang/include/clang/CIR/Dialect/Passes.td @@ -75,6 +75,20 @@ def LoweringPrepare : Pass<"cir-lowering-prepare"> { let dependentDialects = ["cir::CIRDialect"]; } +def FlattenCFG : Pass<"cir-flatten-cfg"> { + let summary = "Produces flatten cfg"; + let description = [{ + This pass transforms CIR and inline all the nested regions.

This change contributes to the implemention of issue #284. `__builtin_convertvector` is implemented as a cast. LLVM IR uses the same instructions for arithmetic conversions of both individual scalars and entire vectors. So ClangIR does the same. The code for handling conversions, in both CodeGen and Lowering, is cleaned up to correctly handle vector types. To simplify the lowering code and avoid `if (type.isa())` statements everywhere, the utility function `elementTypeIfVector` was added to `LowerToLLVM.cpp`. `__builtin_shufflevector` has two forms, only one of which appears to be documented. The documented form, which takes a variable-sized list of integer constants for the indices, is implemented with the new ClangIR operation `cir.vec.shuffle.ints`. This operation is lowered to the `llvm.shufflevector` op. The undocumented form, which gets the indices from a vector operand, is implemented with the new ClangIR operation `cir.vec.shuffle.vec`. LLVM IR does not have an instruction for this, so it gets lowered to a long series of `llvm.extractelement` and `llvm.insertelement` operations. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 63 +++++++ clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 53 +++++- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 61 ++++++- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 172 ++++++++++++++---- clang/test/CIR/CodeGen/vectype.cpp | 11 ++ clang/test/CIR/IR/invalid.cir | 40 +++- clang/test/CIR/Lowering/vectype.cpp | 41 +++++ 7 files changed, 388 insertions(+), 53 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 62b0da234457..d1c7cbe1e774 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2198,6 +2198,69 @@ def VecTernaryOp : CIR_Op<"vec.ternary", let hasVerifier = 1; } +//===----------------------------------------------------------------------===// +// VecShuffle +//===----------------------------------------------------------------------===// + +// TODO: Create an interface that both VecShuffleOp and VecShuffleDynamicOp +// implement.

Vector types other than GNU vector types will be covered by other yet-to-be-created issues. Now that GNU vector types (the ones defined via the vector_size attribute) are implemented, do a final cleanup of the assertions and other checks related to vector types. Remove `UnimplementedFeature::cirVectorType()`. Deal with the remaining calls to that function. When the that is not yet implemented has to do with Arm SVE vectors, the assert was changed to `UnimplementedFeature::scalableVectors()` instead. The assertion was removed in cases where the code correctly handle GNU vector types. While cleaning up the assertion checks, I noticed that BinOp handling of vector types wasn't quite complete. Any special handling for integer or floating-point types wasn't happening when the operands were vector types. To fix this, split `BinOpInfo::Ty` into two fields, `FullType` and `CompType`. `FullType` is the type of the operands. `CompType` is normally the same as `FullType`, but is the element type when `FullType` is a vector type. --- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 94 +++++++++---------- .../CodeGen/UnimplementedFeatureGuarding.h | 5 +- 2 files changed, 48 insertions(+), 51 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp index e6093c52ca84..22c8ffdf96ff 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp @@ -37,7 +37,9 @@ struct BinOpInfo { mlir::Value LHS; mlir::Value RHS; SourceRange Loc; - QualType Ty; // Computation Type. + QualType FullType; // Type of operands and result + QualType CompType; // Type used for computations.

There are several important things though I would like to highlight. 1) Consider the next code from the tests: ``` cir.func @foo(%arg0: !s32i) -> !s32i { %4 = cir.cast(int_to_bool, %arg0 : !s32i), !cir.bool cir.if %4 { %5 = cir.const(#cir.int<1> : !s32i) : !s32i cir.return %5 : !s32i } else { %5 = cir.const(#cir.int<0> : !s32i) : !s32i cir.return %5 : !s32i } cir.return %arg0 : !s32i } ``` The last `cir.return` becomes unreachable after flattening and hence is not reachable in the lowering. So we got the next error: ``` error: 'cir.return' op expects parent op to be one of 'cir.func, cir.scope, cir.if, cir.switch, cir.do, cir.while, cir.for' cir.return %arg0 : !s32i ``` the parent after lowering is `llvm.func`. And this is only the beginning - the more operations will be flatten, the more similar fails will happen. Thus, I added lowering for the unreachable code as well in `LowerToLLVM.cpp`. But may be you have another solution in your mind. 2) Please, pay attention on the flattening pass - I'm not that familiar with `mlir` builders as you are, so may be I'm doing something wrong. The idea was to start flattening from the most nested operations. 3) As you requested in #516, `cir-to-llvm-internal` is renamed to `cir-flat-to-llvm`. The only thing remain undone is related to the following: > Since it would be wrong to run cir-flat-to-llvm without running cir-flatten-cfg, we should make cir-flat-to-llvm pass to require cir-flatten-cfg pass to be run before. And I'm not sure I know how to do it exactly - is there something similar to pass dependencies from LLVM IR? 4) The part of `IfOp` lowering related to elimination of the vain casts for condition branch moved directly to the lowering of `BrCondOp` with some refactoring and guarding. 5) Just note, that now `cir-opt` is able to dump the flat cir as well: `cir-opt -cir-flat-cfg` --- .../lib/CIR/Dialect/Transforms/FlattenCFG.cpp | 67 ++++++- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 180 +++++++++--------- clang/test/CIR/CodeGen/if.cir | 48 +++++ clang/test/CIR/mlirprint.c | 2 +- clang/tools/cir-opt/cir-opt.cpp | 4 + 5 files changed, 203 insertions(+), 98 deletions(-) create mode 100644 clang/test/CIR/CodeGen/if.cir diff --git a/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp b/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp index 477a85df6c26..aa061c51680c 100644 --- a/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp +++ b/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp @@ -30,8 +30,70 @@ struct FlattenCFGPass : public FlattenCFGBase { void runOnOperation() override; }; +struct CIRIfFlattening : public OpRewritePattern { + using OpRewritePattern::OpRewritePattern; + + mlir::LogicalResult + matchAndRewrite(mlir::cir::IfOp ifOp, + mlir::PatternRewriter &rewriter) const override { + mlir::OpBuilder::InsertionGuard guard(rewriter); + auto loc = ifOp.getLoc(); + auto emptyElse = ifOp.getElseRegion().empty(); + + auto *currentBlock = rewriter.getInsertionBlock(); + auto *remainingOpsBlock = + rewriter.splitBlock(currentBlock, rewriter.getInsertionPoint()); + mlir::Block *continueBlock; + if (ifOp->getResults().size() == 0) + continueBlock = remainingOpsBlock; + else + llvm_unreachable("NYI"); + + // Inline then region + auto *thenBeforeBody = &ifOp.getThenRegion().front(); + auto *thenAfterBody = &ifOp.getThenRegion().back(); + rewriter.inlineRegionBefore(ifOp.getThenRegion(), continueBlock); + + rewriter.setInsertionPointToEnd(thenAfterBody); + if (auto thenYieldOp = + dyn_cast(thenAfterBody->getTerminator())) { + rewriter.replaceOpWithNewOp( + thenYieldOp, thenYieldOp.getArgs(), continueBlock); + } + + rewriter.setInsertionPointToEnd(continueBlock); + + // Has else region: inline it. + mlir::Block *elseBeforeBody = nullptr; + mlir::Block *elseAfterBody = nullptr; + if (!emptyElse) { + elseBeforeBody = &ifOp.getElseRegion().front(); + elseAfterBody = &ifOp.getElseRegion().back(); + rewriter.inlineRegionBefore(ifOp.getElseRegion(), thenAfterBody); + } else { + elseBeforeBody = elseAfterBody = continueBlock; + } + + rewriter.setInsertionPointToEnd(currentBlock); + rewriter.create(loc, ifOp.getCondition(), + thenBeforeBody, elseBeforeBody); + + if (!emptyElse) { + rewriter.setInsertionPointToEnd(elseAfterBody); + if (auto elseYieldOp = + dyn_cast(elseAfterBody->getTerminator())) { + rewriter.replaceOpWithNewOp( + elseYieldOp, elseYieldOp.getArgs(), continueBlock); + } + } + + rewriter.replaceOp(ifOp, continueBlock->getArguments()); + return mlir::success(); + } +}; + void populateFlattenCFGPatterns(RewritePatternSet &patterns) { - // TODO: add patterns here + patterns.add(patterns.getContext()); } void FlattenCFGPass::runOnOperation() { @@ -41,7 +103,8 @@ void FlattenCFGPass::runOnOperation() { // Collect operations to apply patterns.

This type goes into the C23 standard, and has already been supported by clang since 2020, previously known as `_ExtInt(N)`. This PR is quite simple and straight-forward. Basically it leverages the existing `cir.int` type to represent such types. Previously `cir.int` verifies that its width must be a multiple of 8, and this verification has been removed in this PR. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 41 ++++----- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 61 ++++++------- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 4 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 10 ++- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 2 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 18 +--- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 12 +-- clang/test/CIR/CodeGen/bitint.c | 22 +++++ clang/test/CIR/CodeGen/bitint.cpp | 86 +++++++++++++++++++ clang/test/CIR/IR/invalid.cir | 25 ++---- clang/test/CIR/Lowering/bitint.cir | 30 +++++++ 11 files changed, 208 insertions(+), 103 deletions(-) create mode 100644 clang/test/CIR/CodeGen/bitint.c create mode 100644 clang/test/CIR/CodeGen/bitint.cpp create mode 100644 clang/test/CIR/Lowering/bitint.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 7da421324fb3..07a79d503f30 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -144,7 +144,7 @@ def ObjSizeOp : CIR_Op<"objsize", [Pure]> { let arguments = (ins CIR_PointerType:$ptr, SizeInfoType:$kind, UnitAttr:$dynamic); - let results = (outs CIR_IntType:$result); + let results = (outs PrimitiveInt:$result); let assemblyFormat = [{ `(` @@ -180,7 +180,7 @@ def PtrDiffOp : CIR_Op<"ptr_diff", [Pure, SameTypeOperands]> { ``` }]; - let results = (outs CIR_IntType:$result); + let results = (outs PrimitiveInt:$result); let arguments = (ins CIR_PointerType:$lhs, CIR_PointerType:$rhs); let assemblyFormat = [{ @@ -208,7 +208,7 @@ def PtrStrideOp : CIR_Op<"ptr_stride", ``` }]; - let arguments = (ins CIR_PointerType:$base, CIR_IntType:$stride); + let arguments = (ins CIR_PointerType:$base, PrimitiveInt:$stride); let results = (outs CIR_PointerType:$result); let assemblyFormat = [{ @@ -337,7 +337,7 @@ def AllocaOp : CIR_Op<"alloca", [ }]; let arguments = (ins - Optional:$dynAllocSize, + Optional:$dynAllocSize, TypeAttr:$allocaType, StrAttr:$name, UnitAttr:$init, @@ -1034,7 +1034,7 @@ class CIR_BitOp }]; } -def BitClrsbOp : CIR_BitOp<"bit.clrsb", SIntOfWidths<[32, 64]>> { +def BitClrsbOp : CIR_BitOp<"bit.clrsb", AnyTypeOf<[SInt32, SInt64]>> { let summary = "Get the number of leading redundant sign bits in the input"; let description = [{ Compute the number of leading redundant sign bits in the input integer. @@ -1065,7 +1065,7 @@ def BitClrsbOp : CIR_BitOp<"bit.clrsb", SIntOfWidths<[32, 64]>> { }]; } -def BitClzOp : CIR_BitOp<"bit.clz", UIntOfWidths<[16, 32, 64]>> { +def BitClzOp : CIR_BitOp<"bit.clz", AnyTypeOf<[UInt16, UInt32, UInt64]>> { let summary = "Get the number of leading 0-bits in the input"; let description = [{ Compute the number of leading 0-bits in the input. @@ -1090,7 +1090,7 @@ def BitClzOp : CIR_BitOp<"bit.clz", UIntOfWidths<[16, 32, 64]>> { }]; } -def BitCtzOp : CIR_BitOp<"bit.ctz", UIntOfWidths<[16, 32, 64]>> { +def BitCtzOp : CIR_BitOp<"bit.ctz", AnyTypeOf<[UInt16, UInt32, UInt64]>> { let summary = "Get the number of trailing 0-bits in the input"; let description = [{ Compute the number of trailing 0-bits in the input. @@ -1115,7 +1115,7 @@ def BitCtzOp : CIR_BitOp<"bit.ctz", UIntOfWidths<[16, 32, 64]>> { }]; } -def BitFfsOp : CIR_BitOp<"bit.ffs", SIntOfWidths<[32, 64]>> { +def BitFfsOp : CIR_BitOp<"bit.ffs", AnyTypeOf<[SInt32, SInt64]>> { let summary = "Get the position of the least significant 1-bit of input"; let description = [{ Compute the position of the least significant 1-bit of the input. @@ -1138,7 +1138,7 @@ def BitFfsOp : CIR_BitOp<"bit.ffs", SIntOfWidths<[32, 64]>> { }]; } -def BitParityOp : CIR_BitOp<"bit.parity", UIntOfWidths<[32, 64]>> { +def BitParityOp : CIR_BitOp<"bit.parity", AnyTypeOf<[UInt32, UInt64]>> { let summary = "Get the parity of input"; let description = [{ Compute the parity of the input.

This is a **final** step (I hope: ) ) from my side to support inline assembly. There are some features that remains unimplemented, but basic things should work now, For example, we can do addition and get the results - I explicitly added several tests for that, so you can test them in real. For instance, the next program being compiled with CIR should give you 7 as the result: ``` int add(int x, int y) { int a; __asm__("addl %[y], %[x]" : "=r" (a) : [x] "r" (x), [y] "r" (y) ); return a; } int main() { printf("run %d\n", add(3, 4)); return 0; } ``` So, the main thing remains is pretty printing. As I said I added several examples, and may be it will become more clear how to print better. Also, I added several tests from original codegen in order to check that we don't fail. And I can add some checks there as well when we come to better solution on printing. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 63 +++- clang/lib/CIR/CodeGen/CIRAsm.cpp | 178 ++++++++- clang/lib/CIR/CodeGen/TargetInfo.h | 8 + .../CodeGen/UnimplementedFeatureGuarding.h | 1 + clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 179 +++++++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 48 ++- clang/test/CIR/CodeGen/asm.c | 339 +++++++++++++++++- clang/test/CIR/Lowering/asm.cir | 62 ++-- 8 files changed, 796 insertions(+), 82 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index fa02176b0a5d..40fb6cc04539 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -31,6 +31,7 @@ include "mlir/Interfaces/SideEffectInterfaces.td" include "mlir/IR/BuiltinAttributeInterfaces.td" include "mlir/IR/EnumAttr.td" include "mlir/IR/SymbolInterfaces.td" +include "mlir/IR/CommonAttrConstraints.td" //===----------------------------------------------------------------------===// // CIR Ops @@ -3329,9 +3330,13 @@ def CIR_InlineAsmOp : CIR_Op<"asm", [RecursiveMemoryEffects]> { - the output variable index referenced by the input operands. - the index of early-clobber operand - Operand attributes is a storage of attributes, where each element corresponds - to the operand with the same index.

Looks like I can't separate this operations and create two PRs, since some errors occur if I do so, e.g. `reference to block defined in another region`. Seems we need to flatten both operations in the same time. Given it's a copy-pasta, I think there is no need to try to make several PRs. I added several tests - just copied them from the lowering part just to demonstrate how it looks like. Note, that changes in `dot.cir` caused by `BrCondOp` updates in the previous PR, when we removed the following casts: ``` %20 = llvm.zext %19 : i1 to i8 %21 = llvm.trunc %20 : i8 to i1 llvm.cond_br %21 ... ``` --- .../lib/CIR/Dialect/Transforms/FlattenCFG.cpp | 158 +++++++++++++++- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 168 ++---------------- clang/test/CIR/CodeGen/loop.cir | 122 +++++++++++++ clang/test/CIR/CodeGen/scope.cir | 60 +++++++ clang/test/CIR/Lowering/dot.cir | 44 +++-- 5 files changed, 376 insertions(+), 176 deletions(-) create mode 100644 clang/test/CIR/CodeGen/loop.cir create mode 100644 clang/test/CIR/CodeGen/scope.cir diff --git a/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp b/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp index aa061c51680c..b9c9481805d7 100644 --- a/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp +++ b/clang/lib/CIR/Dialect/Transforms/FlattenCFG.cpp @@ -24,6 +24,28 @@ using namespace mlir::cir; namespace { +/// Lowers operations with the terminator trait that have a single successor. +void lowerTerminator(mlir::Operation *op, mlir::Block *dest, + mlir::PatternRewriter &rewriter) { + assert(op->hasTrait() && "not a terminator"); + mlir::OpBuilder::InsertionGuard guard(rewriter); + rewriter.setInsertionPoint(op); + rewriter.replaceOpWithNewOp(op, dest); +} + +/// Walks a region while skipping operations of type `Ops`.

Basically, the default behavior is no overlap: ``` void baz(int x, int y) { int z = x - y; } ``` LLVM IR (no CIR enabled): ``` %sub = sub nsw i32 %0, %1 ``` and with `-fwrapv` : ``` %sub = sub i32 %0, %1 ``` We need something similar in CIR. The only way I see how to implement it is to add a couple of attributes to the `BinOp` to make things even with the llvm dialect. Well, are there any other ideas? --------- Co-authored-by: Bruno Cardoso Lopes --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 15 ++++++++++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 12 +++++--- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 19 ++++++------ clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 18 +++++++++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 21 +++++++++++-- clang/test/CIR/CodeGen/binop.cpp | 2 +- clang/test/CIR/CodeGen/call.cpp | 2 +- clang/test/CIR/CodeGen/int-wrap.c | 30 +++++++++++++++++++ clang/test/CIR/IR/invalid.cir | 18 ++++++++++- clang/test/CIR/Lowering/int-wrap.cir | 24 +++++++++++++++ 10 files changed, 141 insertions(+), 20 deletions(-) create mode 100644 clang/test/CIR/CodeGen/int-wrap.c create mode 100644 clang/test/CIR/Lowering/int-wrap.cir diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index b111913a126e..5f4bc1874674 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -140,6 +140,21 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return create(loc, val, dst, _volatile, order);

It contains the following contents: - [x] A new `cir.dyn_cast` operation. - [x] ~Two new attributes that will be attached to `cir.dyn_cast` operations:~ - [x] ~`#cir.dyn_cast_info` attributes, which gives general information about a dynamic cast (e.g. the source RTTI pointer, the dest RTTI pointer, etc.)~ - [x] ~`#cir.downcast_info` attribute, which gives even more detailed information about a dynamic cast that is a down-cast. These information will be used when rewriting the `cir.dyn_cast` operation with more fundamental CIR operations.~ - [x] CIRGen support for the new operation and attributes. - [x] Rewrite the new operation with more fundamental CIR operations in LoweringPrepare. ~This is a draft PR. Now I only added the new operation / attributes, and updated the CIRGen part. The LoweringPrepare for the new operation is not implemented. Hopefully the draft can get some initial feedbacks from the community and make sure it is on the right direction so we don't waste time on wrong things.~ Related issue: #470 . --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 21 ++++ .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 52 ++++++++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 65 ++++++++++ clang/lib/CIR/CodeGen/CIRGenBuilder.h | 20 +-- clang/lib/CIR/CodeGen/CIRGenCXXABI.h | 12 +- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 60 ++++----- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 79 ++++-------- clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 48 +++++++ clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 5 + clang/lib/CIR/Dialect/IR/MissingFeatures.h | 7 ++ .../lib/CIR/Dialect/Transforms/CMakeLists.txt | 1 + .../Dialect/Transforms/LoweringPrepare.cpp | 37 +++++- .../Transforms/LoweringPrepareCXXABI.h | 36 ++++++ .../LoweringPrepareItaniumCXXABI.cpp | 117 ++++++++++++++++++ clang/test/CIR/CodeGen/dynamic-cast.cpp | 112 +++++++++-------- clang/test/CIR/IR/invalid.cir | 44 +++++++ 16 files changed, 553 insertions(+), 163 deletions(-) create mode 100644 clang/lib/CIR/Dialect/Transforms/LoweringPrepareCXXABI.h create mode 100644 clang/lib/CIR/Dialect/Transforms/LoweringPrepareItaniumCXXABI.cpp diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index 5f4bc1874674..659819b17ab2 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -54,6 +54,18 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { getAttr(typ, val)); } + mlir::cir::ConstantOp getConstant(mlir::Location loc, mlir::TypedAttr attr) { + return create(loc, attr.getType(), attr); + } + + mlir::cir::BoolType getBoolTy() { + return ::mlir::cir::BoolType::get(getContext()); + } + + mlir::cir::VoidType getVoidTy() { + return ::mlir::cir::VoidType::get(getContext()); + } + mlir::cir::PointerType getVoidPtrTy(unsigned AddrSpace = 0) { if (AddrSpace) llvm_unreachable("address space is NYI"); @@ -181,6 +193,11 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { mlir::cir::CastKind::ptr_to_int, src); } + mlir::Value createPtrToBoolCast(mlir::Value v) { + return create(v.getLoc(), getBoolTy(), + mlir::cir::CastKind::ptr_to_bool, v); + } + // TODO(cir): the following function was introduced to keep in sync with LLVM // codegen.

From 62e7efc1bea0f4172f7c55e64e7e815945808526 Mon Sep 17 00:00:00 2001 From: Sirui Mu Date: Fri, 19 Apr 2024 13:08:54 +0800 Subject: [PATCH 1510/2301] [CIR] Add support for long double type (#536) This PR adds support for the `long double` type in C/C++. It includes a new CIR type `!cir.long_double` to represent the `long double` type. CIRGen and LLVMIR lowering support for the new type is also added. Since the underlying floating point format used by a `long double` value is implementation-defined, the `!cir.long_double` type is parameterized to include information about the underlying floating point format. Specifically, a `long double` value may have one of the following formats: 1) IEEE-754 binary64 format (i.e. the same format used by `double`); 2) x87 80-bit floating point format; 3) IEEE-754 binary128 format; 4) PowerPC double double format. This PR invents 3 more CIR types to represent the above floating-point formats, and `!cir.long_double` is parameterized by another CIR floating-point type which represents its underlying format: - `!cir.long_double` represents the 1st variant above; - `!cir.long_double` represents the 2nd variant above; - `!cir.long_double` represents the 3rd variant above; - `!cir.long_double` represents the 4th variant above.

This is pre req work for computing alignment based on elements offsets, very soon we're gonna also store of array of offsets. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 36 ++++++++++++++ clang/include/clang/CIR/Dialect/IR/CIRTypes.h | 7 +-- clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 6 +++ clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 48 +++++++++---------- 4 files changed, 70 insertions(+), 27 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 14e8ac9de21e..c5c98372eab1 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -511,6 +511,42 @@ def VTableAttr : CIR_Attr<"VTable", "vtable", [TypedAttrInterface]> { }]; } +//===----------------------------------------------------------------------===// +// StructLayoutAttr +//===----------------------------------------------------------------------===// + +// Used to decouple layout information from the struct type.

This PR lowers certain `cir.cmp3way` operations to these intrinsics. Not all `cir.cmp3way` operations can be lowered to these intrinsics. The qualifying conditions are: 1) the comparison is between two integers, and 2) the comparison produces a strong ordering. `cir.cmp3way` operations that are not qualified are not affected by this PR. Qualifying `cir.cmp3way` operations may still need some canonicalization work before lowering. The "canonicalized" form of a qualifying three-way comparison operation yields -1 for lt, 0 for eq, and 1 for gt. This PR converts those non-canonicalized but qualifying `cir.cmp3way` operations to their canonical forms in the LLVM lowering prepare pass.

Missing support to add in the future: - Non-default auto initialization setting. The default is to not initialize the allocated buffer, which is simpler to implement. This commit is leaving the skeleton to implement this feature following clang's codegen pattern. - It may be possible that the frontend has set non-default address space for the alloca's return value.

This means that CIR pointers would now always be printed as `!cir.ptr`, so update all tests that had a space before the bracket (i.e., `!cir.ptr `) or missing the type alias prefix (`cir.ptr` instead of `!cir.ptr`). --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 68 +++++++-------- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 4 +- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 17 ----

`__builtin_add_overflow` and `__builtin_{s|u}add{|l|ll}_overflow`; - `__builtin_sub_overflow` and `__builtin_{s|u}sub{|l|ll}_overflow`; - `__builtin_mul_overflow` and `__builtin_{s|u}mul{|l|ll}_overflow`. This patch adds a new operation `cir.checked_arith` to represent these builtins. Unlike other CIR operations, this new operation has two result values. One for the possibly truncated result, and the other for a boolean flag that indicates whether the operation has overflowed. CIRGen and LLVMIR lowering support for the new operation is both included in this PR. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 13 + clang/include/clang/CIR/Dialect/IR/CIROps.td | 58 +++ clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 197 ++++++++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 144 ++++++- clang/test/CIR/CodeGen/builtins-overflow.cpp | 364 ++++++++++++++++++ clang/test/CIR/Lowering/binop-overflow.cir | 67 ++++ 6 files changed, 836 insertions(+), 7 deletions(-) create mode 100644 clang/test/CIR/CodeGen/builtins-overflow.cpp create mode 100644 clang/test/CIR/Lowering/binop-overflow.cir diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index 110bedf5e456..7102b2da91d0 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -205,6 +205,19 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return createSub(lhs, rhs, false, true); } + struct BinOpOverflowResults { + mlir::Value result; + mlir::Value overflow; + }; + + BinOpOverflowResults createBinOpOverflowOp(mlir::Location loc, + mlir::cir::IntType resultTy, + mlir::cir::BinOpOverflowKind kind, + mlir::Value lhs, mlir::Value rhs) { + auto op = create(loc, resultTy, kind, lhs, rhs); + return {op.getResult(), op.getOverflow()}; + } + //===--------------------------------------------------------------------===// // Cast/Conversion Operators //===--------------------------------------------------------------------===// diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 6c5a1171b3d5..14642f4db55d 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -1077,6 +1077,64 @@ def CmpOp : CIR_Op<"cmp", [Pure, SameTypeOperands]> { let hasVerifier = 0; } +//===----------------------------------------------------------------------===// +// BinOpOverflowOp +//===----------------------------------------------------------------------===// + +def BinOpOverflowKind : I32EnumAttr< + "BinOpOverflowKind", + "checked binary arithmetic operation kind", + [BinOpKind_Add, BinOpKind_Sub, BinOpKind_Mul]> { + let cppNamespace = "::mlir::cir"; +} + +def BinOpOverflowOp : CIR_Op<"binop.overflow", [Pure, SameTypeOperands]> { + let summary = "Perform binary integral arithmetic with overflow checking"; + let description = [{ + `cir.binop.overflow` performs binary arithmetic operations with overflow + checking on integral operands. + + The `kind` argument specifies the kind of arithmetic operation to perform. + It can be either `add`, `sub`, or `mul`.

There are three available stages to place the simplification in. * A straightforward method is to extend `fold` method for CastOp. But CIR does not use CanonicalizerPass, so it does not work. * As for somehow equivalent to it, append a pattern to `MergeCleanupsPass`. But now it is mainly for CFG-related simplifications like block merging. I don't know if this is the proper way. Shall we rename it to a broader definition? * Add a new pass for this issue. This is definitely not very reasonable XD. We won't consider it unless we're really out of options. This PR includes the second option.

It also includes a new Clang command line option to enable it. Also, it is considered a part of the lowering prepare set of passes, as it is unlikely to be used elsewhere in the pipeline. Since this will be dealing with ABI/Target-specific information, it requires AST info. For this reason, it can only be executed through the clang driver or cc1 tool for now as CIR does not encode AST info.

This patch introduces `-fclangir-analysis-only` option to allow the users to consume the AST to the CIR (and potential analysis passes, this can be done by specifying `-Xclang -fclangir-lifetime-check=""` now or some default value in following patches) and also generating the LLVM IR by the traditional code gen path. This will be helpful to use CIR with real world projects without worrying the correctness and completeness of CIR CodeGen part. --- .../clang/CIRFrontendAction/CIRGenAction.h | 3 +++ .../clang/CIRFrontendAction/CIRGenConsumer.h | 0 clang/include/clang/Driver/Options.td | 5 ++++ .../include/clang/Frontend/FrontendOptions.h | 7 +++++- clang/lib/CIR/FrontendAction/CIRGenAction.cpp | 8 ++++++ clang/lib/CodeGen/CMakeLists.txt | 8 ++++++ clang/lib/CodeGen/CodeGenAction.cpp | 25 +++++++++++++++---- clang/lib/Driver/ToolChains/Clang.cpp | 9 +++++++ clang/lib/Frontend/CompilerInvocation.cpp | 4 +-- clang/test/CIR/CodeGen/analysis-only.cpp | 8 ++++++ .../CIR/Transforms/lifetime-check-agg.cpp | 1 + clang/test/CIR/analysis-only.cpp | 2 ++ 12 files changed, 72 insertions(+), 8 deletions(-) create mode 100644 clang/include/clang/CIRFrontendAction/CIRGenConsumer.h create mode 100644 clang/test/CIR/CodeGen/analysis-only.cpp create mode 100644 clang/test/CIR/analysis-only.cpp diff --git a/clang/include/clang/CIRFrontendAction/CIRGenAction.h b/clang/include/clang/CIRFrontendAction/CIRGenAction.h index 74d5e5e32611..bcfca9bfcd89 100644 --- a/clang/include/clang/CIRFrontendAction/CIRGenAction.h +++ b/clang/include/clang/CIRFrontendAction/CIRGenAction.h @@ -120,6 +120,9 @@ class EmitObjAction : public CIRGenAction { EmitObjAction(mlir::MLIRContext *mlirCtx = nullptr); }; +std::unique_ptr +createCIRAnalysisOnlyConsumer(clang::CompilerInstance &); + } // namespace cir #endif diff --git a/clang/include/clang/CIRFrontendAction/CIRGenConsumer.h b/clang/include/clang/CIRFrontendAction/CIRGenConsumer.h new file mode 100644 index 000000000000..e69de29bb2d1 diff --git a/clang/include/clang/Driver/Options.td b/clang/include/clang/Driver/Options.td index a8651fcffb34..3a8e02d7dfef 100644 --- a/clang/include/clang/Driver/Options.td +++ b/clang/include/clang/Driver/Options.td @@ -3104,6 +3104,11 @@ defm clangir_direct_lowering : BoolFOption<"clangir-direct-lowering", FrontendOpts<"ClangIRDirectLowering">, DefaultTrue, PosFlag, NegFlag>; +defm clangir_analysis_only : BoolFOption<"clangir-analysis-only", + FrontendOpts<"ClangIRAnalysisOnly">, DefaultFalse, + PosFlag, + NegFlag>; def emit_cir : Flag<["-"], "emit-cir">, Visibility<[CC1Option]>, Group, HelpText<"Build ASTs and then lower to ClangIR, emit the .cir file">; diff --git a/clang/include/clang/Frontend/FrontendOptions.h b/clang/include/clang/Frontend/FrontendOptions.h index 5bff487c2068..5bcf873ff98f 100644 --- a/clang/include/clang/Frontend/FrontendOptions.h +++ b/clang/include/clang/Frontend/FrontendOptions.h @@ -451,6 +451,10 @@ class FrontendOptions { // Enable Clang IR call conv lowering pass. unsigned ClangIREnableCallConvLowering : 1; + // Enable Clang IR analysis only pipeline that uses tranditional code gen + // pipeline. + unsigned ClangIRAnalysisOnly : 1; + CodeCompleteOptions CodeCompleteOpts; /// Specifies the output format of the AST. @@ -650,7 +654,8 @@ class FrontendOptions { ClangIRDisablePasses(false), ClangIRDisableCIRVerifier(false), ClangIRDisableEmitCXXDefault(false), ClangIRLifetimeCheck(false), ClangIRIdiomRecognizer(false), ClangIRLibOpt(false), - TimeTraceGranularity(500), TimeTraceVerbose(false) {} + ClangIRAnalysisOnly(false), TimeTraceGranularity(500), + TimeTraceVerbose(false) {} /// getInputKindForExtension - Return the appropriate input kind for a file /// extension.

Basically it's a copy-pasta from the original `codegen`. The only thing that I doubt about is what exact operation I need to create in CIR. The first approach I used was to create `AtomicRMW` operation in CIR. But as far as I see I can use the existing `AtomicFetch` instead. Is it correct? or it's better to add a new op here? --- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 91 +++++++++++++++++++++++++ clang/test/CIR/CodeGen/atomic.cpp | 43 +++++++++++- 2 files changed, 133 insertions(+), 1 deletion(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index 0e801d05e41e..02218a691b7a 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -26,6 +26,7 @@ #include "clang/AST/GlobalDecl.h" #include "clang/Basic/Builtins.h" #include "clang/Basic/TargetBuiltins.h" +#include "clang/Frontend/FrontendDiagnostic.h" #include "mlir/Dialect/Func/IR/FuncOps.h" #include "mlir/IR/Value.h" @@ -167,6 +168,86 @@ EncompassingIntegerType(ArrayRef Types) { return {Width, Signed};

It also moves the feature guarding logic into CIR's root include folder so that any CIR library may use it. --- .../clang/CIR/MissingFeatures.h} | 35 ++-- clang/lib/CIR/CodeGen/CIRAsm.cpp | 18 +- clang/lib/CIR/CodeGen/CIRGenAtomic.cpp | 14 +- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 14 +- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 8 +- .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenBuiltinX86.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenCXX.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 16 +- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 38 ++-- clang/lib/CIR/CodeGen/CIRGenCleanup.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 42 ++-- clang/lib/CIR/CodeGen/CIRGenDeclCXX.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenException.cpp | 14 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 182 +++++++++--------- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 40 ++-- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 18 +- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 49 +++-- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 62 +++--- clang/lib/CIR/CodeGen/CIRGenFunction.h | 8 +- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 42 ++-- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 68 ++++--- clang/lib/CIR/CodeGen/CIRGenModule.h | 2 +- clang/lib/CIR/CodeGen/CIRGenOpenMPRuntime.cpp | 18 +- clang/lib/CIR/CodeGen/CIRGenOpenMPRuntime.h | 2 +- clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 44 ++--- clang/lib/CIR/CodeGen/CIRGenTypeCache.h | 4 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenVTables.cpp | 4 +- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 2 +- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 3 +- clang/lib/CIR/Dialect/IR/MissingFeatures.h | 43 ----- .../LoweringPrepareAArch64CXXABI.cpp | 2 +- .../LoweringPrepareItaniumCXXABI.cpp | 2 +- 36 files changed, 392 insertions(+), 426 deletions(-) rename clang/{lib/CIR/CodeGen/UnimplementedFeatureGuarding.h => include/clang/CIR/MissingFeatures.h} (86%) delete mode 100644 clang/lib/CIR/Dialect/IR/MissingFeatures.h diff --git a/clang/lib/CIR/CodeGen/UnimplementedFeatureGuarding.h b/clang/include/clang/CIR/MissingFeatures.h similarity index 86% rename from clang/lib/CIR/CodeGen/UnimplementedFeatureGuarding.h rename to clang/include/clang/CIR/MissingFeatures.h index 09ab264be1ad..439c57afb6a0 100644 --- a/clang/lib/CIR/CodeGen/UnimplementedFeatureGuarding.h +++ b/clang/include/clang/CIR/MissingFeatures.h @@ -1,4 +1,4 @@ -//===---- UnimplementedFeatureGuarding.h - Checks against NYI ---*- C++ -*-===// +//===---- MissingFeatures.h - Checks for unimplemented features -*- C++ -*-===// // // Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. // See https://llvm.org/LICENSE.txt for license information. @@ -7,16 +7,17 @@ //===----------------------------------------------------------------------===// // // This file introduces some helper classes to guard against features that -// CodeGen supports that we do not have and also do not have great ways to +// CIR dialect supports that we do not have and also do not have great ways to // assert against. // //===----------------------------------------------------------------------===// -#ifndef LLVM_CLANG_LIB_CIR_UFG -#define LLVM_CLANG_LIB_CIR_UFG +#ifndef CLANG_CIR_MISSINGFEATURES_H +#define CLANG_CIR_MISSINGFEATURES_H namespace cir { -struct UnimplementedFeature { + +struct MissingFeatures { // TODO(CIR): Implement the CIRGenFunction::buildTypeCheck method that handles // sanitizer related type check features static bool buildTypeCheck() { return false;

Mu Date: Thu, 6 Jun 2024 05:27:51 +0800 Subject: [PATCH 1615/2301] [CIR][LLVMLowering] Add LLVM lowering for unary fp2fp builtins (#651) This patch adds LLVM lowering support for unary fp2fp builtins. Those builtins that should be lowered to runtime function calls are lowered to such calls during lowering prepare. Other builtins are lowered to LLVM intrinsic calls during LLVM lowering. --- .../Dialect/Transforms/LoweringPrepare.cpp | 126 +++-- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 38 +- .../test/CIR/CodeGen/builtin-floating-point.c | 458 ++++++++++++++++++ 3 files changed, 569 insertions(+), 53 deletions(-) diff --git a/clang/lib/CIR/Dialect/Transforms/LoweringPrepare.cpp b/clang/lib/CIR/Dialect/Transforms/LoweringPrepare.cpp index bbda97e45c80..02b54c5a9962 100644 --- a/clang/lib/CIR/Dialect/Transforms/LoweringPrepare.cpp +++ b/clang/lib/CIR/Dialect/Transforms/LoweringPrepare.cpp @@ -25,6 +25,7 @@ #include "llvm/ADT/StringMap.h" #include "llvm/ADT/StringRef.h" #include "llvm/ADT/Twine.h" +#include "llvm/ADT/TypeSwitch.h" #include "llvm/Support/ErrorHandling.h" #include "llvm/Support/Path.h" @@ -71,6 +72,7 @@ struct LoweringPreparePass : public LoweringPrepareBase { void runOnOperation() override;

It is largely based on the original codegen library used to lower AST nodes to ABI/Target -specific LLVM IR instructions. Because of this, each file has a comment specifying the original codegen file that inspired the new file. The idea is that anyone who wishes to expand this library can look at the original codegen file to understand how to implement the new feature. In some cases, CIRGen defers the handling of ABI/target-specific details for a later stage in the pipeline. One reason for this is to keep the intermediate representation on a higher-level, which makes it easier to reason about and to perform optimizations. However, we still need to lower such representation to a target-specific format at some point. Some examples are ctor/dtors and calling conventions, which are not fully handled by CIRGen. The new library will be responsible for these lowerings. Some files are empty but will eventually be used and a few getters and methods where added to avoid unused warnings. Missing features in this library are tracked in a dedicated MissingFeature.h header. --- clang/include/clang/CIR/ABIArgInfo.h | 226 ++++++++++++++++++ clang/include/clang/CIR/MissingFeatures.h | 21 ++ clang/lib/CIR/CodeGen/CIRGenFunctionInfo.h | 200 +--------------- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 4 + .../lib/CIR/Dialect/Transforms/CMakeLists.txt | 5 +- .../Dialect/Transforms/CallConvLowering.cpp | 41 ++++ .../Transforms/TargetLowering/ABIInfo.cpp | 23 ++ .../Transforms/TargetLowering/ABIInfo.h | 40 ++++ .../Transforms/TargetLowering/ABIInfoImpl.cpp | 12 + .../Transforms/TargetLowering/ABIInfoImpl.h | 21 ++ .../Transforms/TargetLowering/CIRCXXABI.cpp | 22 ++ .../Transforms/TargetLowering/CIRCXXABI.h | 72 ++++++ .../TargetLowering/CIRLowerContext.cpp | 62 +++++ .../TargetLowering/CIRLowerContext.h | 74 ++++++ .../TargetLowering/CIRRecordLayout.cpp | 22 ++ .../TargetLowering/CIRRecordLayout.h | 33 +++ .../TargetLowering/CIRToCIRArgMapping.h | 60 +++++ .../Transforms/TargetLowering/CMakeLists.txt | 28 +++ .../TargetLowering/ItaniumCXXABI.cpp | 64 +++++ .../Transforms/TargetLowering/LowerCall.cpp | 0 .../Transforms/TargetLowering/LowerCall.h | 50 ++++ .../TargetLowering/LowerFunction.cpp | 36 +++ .../Transforms/TargetLowering/LowerFunction.h | 58 +++++ .../TargetLowering/LowerFunctionInfo.h | 134 +++++++++++ .../Transforms/TargetLowering/LowerModule.cpp | 91 +++++++ .../Transforms/TargetLowering/LowerModule.h | 77 ++++++ .../Transforms/TargetLowering/LowerTypes.cpp | 24 ++ .../Transforms/TargetLowering/LowerTypes.h | 59 +++++ .../TargetLowering/RecordLayoutBuilder.cpp | 12 + .../Transforms/TargetLowering/TargetInfo.cpp | 12 + .../Transforms/TargetLowering/TargetInfo.h | 36 +++ .../TargetLowering/TargetLoweringInfo.cpp | 12 + .../TargetLowering/TargetLoweringInfo.h | 38 +++ .../Targets}/LoweringPrepareAArch64CXXABI.cpp | 4 +- .../Targets}/LoweringPrepareItaniumCXXABI.cpp | 4 +- .../Transforms/TargetLowering/Targets/X86.cpp | 31 +++ 36 files changed, 1505 insertions(+), 203 deletions(-) create mode 100644 clang/include/clang/CIR/ABIArgInfo.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/ABIInfo.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/ABIInfo.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/ABIInfoImpl.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/ABIInfoImpl.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CIRCXXABI.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CIRCXXABI.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CIRLowerContext.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CIRLowerContext.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CIRRecordLayout.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CIRRecordLayout.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CIRToCIRArgMapping.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/CMakeLists.txt create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/ItaniumCXXABI.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerCall.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerCall.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunctionInfo.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerModule.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerModule.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerTypes.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerTypes.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/RecordLayoutBuilder.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/TargetInfo.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/TargetInfo.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/TargetLoweringInfo.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/TargetLoweringInfo.h rename clang/lib/CIR/Dialect/Transforms/{ => TargetLowering/Targets}/LoweringPrepareAArch64CXXABI.cpp (99%) rename clang/lib/CIR/Dialect/Transforms/{ => TargetLowering/Targets}/LoweringPrepareItaniumCXXABI.cpp (98%) create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/Targets/X86.cpp diff --git a/clang/include/clang/CIR/ABIArgInfo.h b/clang/include/clang/CIR/ABIArgInfo.h new file mode 100644 index 000000000000..08317d62297f --- /dev/null +++ b/clang/include/clang/CIR/ABIArgInfo.h @@ -0,0 +1,226 @@ +//==-- ABIArgInfo.h -

This means they are going to show up in both. We don't support that just yet, hence the PR. CIR has an attribute `ExtraFuncAttr` that we current use as part of `FuncOp`, see CIROps.td. This attribute also needs to be added to `CallOp` and `TryCalOp`. Right now, In `CIRGenCall.cpp: AddAttributesFromFunctionProtoType` fills in `FuncAttrs`, but doesn't use it for anything. We should use the `FuncAttrs` result to populate constructing a `ExtraFuncAttr` and add it to the aforementioned call operations. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 51 +++++++++++++++++++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 25 ++++----- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 32 +++++++----- clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 13 +++-- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 4 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 39 ++++++++++++-- .../Dialect/Transforms/LoweringPrepare.cpp | 25 +++++---- .../TargetLowering/LowerFunction.cpp | 5 +- .../Targets/LoweringPrepareItaniumCXXABI.cpp | 6 +-- clang/test/CIR/CodeGen/call-extra-attrs.cpp | 34 +++++++++++++ 10 files changed, 174 insertions(+), 60 deletions(-) create mode 100644 clang/test/CIR/CodeGen/call-extra-attrs.cpp diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index 9420b24e42e0..cb7bb85617f5 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -415,6 +415,57 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { mlir::ValueRange value = {}) { return create(loc, value);

It includes the following changes: - ~~The `#cir.data_member` attribute now has a new parameter named `memberOffset`. When the data member pointer is not null, this parameter gives the offset of the pointed-to member within its containing object. This offset is calculated by target ABI.~~ - ~~A new attribute `#cir.data_member_ptr_layout` is added. It contains ABI-specific layout information about a data member pointer that is required to lower it to LLVM IR. This attribute is attached to the module op, and it is queried during LLVMIR lowering to obtain the lowering information in it.~~ - Some CIRGen of the data member pointers is refactored to follow the upstream CodeGen skeleton. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 12 ++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 2 +- clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 2 +- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 82 +++++++++++++++---- clang/test/CIR/Lowering/data-member.cir | 52 ++++++++++++ 5 files changed, 131 insertions(+), 19 deletions(-) create mode 100644 clang/test/CIR/Lowering/data-member.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 8c68c54a4159..9285cade6953 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -345,12 +345,12 @@ def DataMemberAttr : CIR_Attr<"DataMember", "data_member", let parameters = (ins AttributeSelfTypeParameter< "", "mlir::cir::DataMemberType">:$type, OptionalParameter< - "std::optional">:$memberIndex); + "std::optional">:$member_index); let description = [{ A data member attribute is a literal attribute that represents a constant pointer-to-data-member value. - The `memberIndex` parameter represents the index of the pointed-to member + The `member_index` parameter represents the index of the pointed-to member within its containing struct.

Fixes the BinOp lowering to MLIR issue where signed numbers were not handled correctly, and adds support for vector types. The corresponding test files have been modified. 2. Fixes the CmpOp lowering to MLIR issue where signed numbers were not handled correctly And modified test files. 3. Adds cir.vec.cmp lowering to MLIR along with the corresponding test files. I originally planned to complete the remaining cir.vec.* lowerings in this PR, but it seems there's quite a lot to do, so I'll split it into multiple PRs. --------- Co-authored-by: Kritoooo ---

From d151f0cf145feda51032185cc470cbc57b666c08 Mon Sep 17 00:00:00 2001 From: akashi Date: Fri, 21 Jun 2024 00:52:18 +0300 Subject: [PATCH 1650/2301] [CIR][CodeGen] Fix missing 'nsw' flag in add, sub, and mul in binop operator (#677) This PR is to fix the missing **nsw** flag in issue #664 regarding add, mul arithmetic operations. there is also a problem with unary operations such as **Inc ,Dec,Plus,Minus and Not** . which should also have 'nsw' flag [example](https://godbolt.org/z/q3o3jsbe1). This part should need to be fixed through lowering. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 39 ++++++++++- clang/include/clang/CIR/Dialect/IR/CIRTypes.h | 2 +-

11:19:16 -0300 Subject: [PATCH 1651/2301] [CIR][ABI][NFC] Prime AArch64 CC lowering (#679) This patch is a preparation for the AArch64 calling convention lowering. It adds the basic infrastructure to initialize the AArch64 ABI details and validates it against a trivial void return and argument call conv lowering. --- clang/include/clang/CIR/Target/AArch64.h | 17 ++++ clang/include/clang/CIR/Target/x86.h | 7 ++ clang/lib/CIR/CodeGen/TargetInfo.cpp | 7 +- .../Dialect/Transforms/LoweringPrepare.cpp | 1 - .../Transforms/LoweringPrepareCXXABI.h | 11 +-- .../Transforms/TargetLowering/CIRCXXABI.h | 10 +-- .../Transforms/TargetLowering/CMakeLists.txt | 1 + .../TargetLowering/ItaniumCXXABI.cpp | 18 ++++- .../Transforms/TargetLowering/LowerModule.cpp | 14 ++++ .../Transforms/TargetLowering/TargetInfo.h | 14 ++-- .../TargetLowering/Targets/AArch64.cpp | 79 +++++++++++++++++++ .../Transforms/TargetLowering/Targets/X86.cpp | 2 + .../CIR/Lowering/DirectToLLVM/CMakeLists.txt | 1 + .../CIR/Lowering/ThroughMLIR/CMakeLists.txt | 1 + .../aarch64-call-conv-lowering-pass.cpp | 8 ++ 15 files changed, 163 insertions(+), 28 deletions(-) create mode 100644 clang/include/clang/CIR/Target/AArch64.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/Targets/AArch64.cpp create mode 100644 clang/test/CIR/Transforms/Target/aarch64/aarch64-call-conv-lowering-pass.cpp diff --git a/clang/include/clang/CIR/Target/AArch64.h b/clang/include/clang/CIR/Target/AArch64.h new file mode 100644 index 000000000000..0788cab1fa71 --- /dev/null +++ b/clang/include/clang/CIR/Target/AArch64.h @@ -0,0 +1,17 @@ + +#ifndef CIR_AAARCH64_H +#define CIR_AAARCH64_H + +namespace cir { + +/// The ABI kind for AArch64 targets. +enum class AArch64ABIKind { + AAPCS = 0, + DarwinPCS, + Win64, + AAPCSSoft, +};

charset=UTF-8 Content-Transfer-Encoding: 8bit as title. In this PR 1. make setDSOLocal an interface function. 2. implemented shouldAssumeDSOLocal function in CIRGenModule, using the same skeleton as shouldAssumeDSOLocal in OG's CodeGenModule.cpp. 3. added call sites of setDSOLocal within CIRGenModule, like what's in OG's CodeGenModule. 4. fixed printing format 5. LLVM lowering 6. keep CIRGenModule::setDSOLocal(mlir::Operation *Op) wrapper at call sites, so if we make changes to interface, we don't have to touch call sites since there are many. We don't have LLVM test for this PR yet, and it will be addressed by the next PR,: **TODO in the next PR:** 1. Implement setNonAliasAttributes in CIRGenModule.cpp, which should be called by CIRGenModule::buildGlobalFunctionDefinition. That way, we will set dso_local correctly for all func ops who have defs in the module. That way we should have LLVM test case in this next PR. detailed explanation below: Since LLVM asm printer omits dso_local in [isImplicitDSOLocal](https://github.com/llvm/clangir/blob/main/llvm/lib/IR/AsmWriter.cpp#L3689)(), and all we cover so far in CIR all fall into this category, we're not able to have a LLVM test. However, the case [isDeclarationForLinker()](https://github.com/llvm/clangir/blob/c28908396a3ba7bda6345907233e4f5c4e53a33e/clang/lib/CodeGen/CodeGenModule.cpp#L1655) should have a lot of test examples as all func defs should have dso_local, We don't have it CIR is because A to-do in our CG. When OG is building func def, after code is generated, it will call setDSOLocal again via setNonAliasAttributes—>SetCommonAttributes—>setGVProperties. The key difference is now GV is not declaration anymore. so satisfies the test if (!GV->isDeclarationForLinker()) return true; https://github.com/llvm/clangir/blob/f78f9a55e7cd6b9e350556e35097616676cf1f3e/clang/lib/CodeGen/CodeGenModule.cpp#L5864 But our CG missed this step of calling setNonAliasAttributes so it won’t give setDSOLocal another chance to get it right https://github.com/llvm/clangir/blob/c28908396a3ba7bda6345907233e4f5c4e53a33e/clang/lib/CIR/CodeGen/CIRGenModule.cpp#L496 **TODO in the next next PR** 2. add call to setDSOLocal in other parts of CG other than CIRGenModule. 3. implement DefaultVisibility check, didn't do in this PR as LLVM::DefaultVisibility has no direct counterpart in [MLIR::](mlir::SymbolTable::Visibility). Therefore, it takes care examination of cases to see what is the best emulation of hasDefaultVisibility in MLIR/CIR context as far as dsolocal is concerned. **TODO in future** other than DefaultVisibility check, we didn't implement canBenefitFromLocalAlias as it depends on other missing features like setComDat. There is a lot of cases we need to cover, so this is just the first step! --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 3 + .../clang/CIR/Interfaces/CIROpInterfaces.h | 1 + .../clang/CIR/Interfaces/CIROpInterfaces.td | 21 ++++ clang/include/clang/CIR/MissingFeatures.h | 2 + clang/lib/CIR/CodeGen/CIRGenModule.cpp | 103 +++++++++++++++++- clang/lib/CIR/CodeGen/CIRGenModule.h | 3 + clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 4 + clang/lib/CIR/Interfaces/CIROpInterfaces.cpp | 9 ++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 6 +- clang/test/CIR/CodeGen/array.cpp | 2 +- clang/test/CIR/CodeGen/const-array.c | 2 +- clang/test/CIR/CodeGen/coro-task.cpp | 2 +- clang/test/CIR/CodeGen/globals.cpp | 4 +- clang/test/CIR/CodeGen/hello.c | 2 +- clang/test/CIR/CodeGen/lambda.cpp | 10 +- clang/test/CIR/CodeGen/libcall.cpp | 4 +- clang/test/CIR/CodeGen/linkage.c | 2 +- clang/test/CIR/CodeGen/static-vars.c | 16 +-- clang/test/CIR/CodeGen/static-vars.cpp | 12 +- clang/test/CIR/CodeGen/stmtexpr-init.c | 2 +- clang/test/CIR/CodeGen/wide-string.cpp | 8 +- 21 files changed, 182 insertions(+), 36 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 44724c079d09..eb281891e8c5 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -1924,6 +1924,7 @@ def GlobalOp : CIR_Op<"global", // Note this can also be a FlatSymbolRefAttr OptionalAttr:$initial_value, UnitAttr:$constant, + UnitAttr:$dsolocal, OptionalAttr:$alignment, OptionalAttr:$ast, OptionalAttr:$section @@ -1934,6 +1935,7 @@ def GlobalOp : CIR_Op<"global", (`constant` $constant^)?

fixes #702. I used a slightly modified version of the `clang-tidy` check provided in https://discourse.llvm.org/t/psa-deprecating-cast-isa-methods-in-some-classes/70909 to rewrite the C++ source files, regular expressions for the TableGen files, and manual cleanups where needed (e.g. chains like `x.foo().cast().bar().cast()`) I applied the following heuristic to determine which namespace prefix to use: - If the target type is not qualified, and the TU has `using namespace mlir` or the code is inside the `mlir` namespace -> use a plain `isa`/`cast`/... - Exception: Always qualify inside custom types and attributes, because their base classes define the very members we want to get rid of. - Else. i.e. the target type is qualified as `::mlir::` or `mlir::`, use that prefix. The `clang-tidy` check also rewrote `dyn_cast_or_null` to `dyn_cast_if_present`. I think that's useful because the former variant is going to be deprecated as well in the future. I'm using `-Werror=deprecated-declarations` to test the change (see 6b7420a93278ee01d37d95882dec39358378cfb3); this required also changing two occurrences of `StringRef::equals` to `==`. I could also just drop the commit here; maybe we want to enable `-Werror` in general (there aren't too many other warnings left in the codebase). --------- Signed-off-by: Julian Oppermann --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 23 +- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 14 +- .../clang/CIR/Dialect/IR/CIRDataLayout.h | 9 +- clang/include/clang/CIR/Dialect/IR/CIROps.td | 26 +- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 71 ++-- clang/lib/CIR/CMakeLists.txt | 7 + clang/lib/CIR/CodeGen/Address.h | 11 +- clang/lib/CIR/CodeGen/CIRAsm.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenAtomic.cpp | 14 +- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 85 ++--- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 15 +- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 9 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 25 +- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 52 +-- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 85 ++--- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenFunction.h | 4 +- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 14 +- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 24 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenVTables.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenValue.h | 2 +- clang/lib/CIR/CodeGen/ConstantInitBuilder.cpp | 4 +- clang/lib/CIR/CodeGen/ConstantInitBuilder.h | 2 +- clang/lib/CIR/CodeGen/TargetInfo.cpp | 4 +- clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 30 +- clang/lib/CIR/Dialect/IR/CIRDataLayout.cpp | 8 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 211 +++++------ clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 42 +-- .../Dialect/Transforms/CallConvLowering.cpp | 9 +- clang/lib/CIR/Dialect/Transforms/DropAST.cpp | 2 +- .../lib/CIR/Dialect/Transforms/FlattenCFG.cpp | 10 +- .../Dialect/Transforms/IdiomRecognizer.cpp | 6 +- clang/lib/CIR/Dialect/Transforms/LibOpt.cpp | 10 +- .../CIR/Dialect/Transforms/LifetimeCheck.cpp | 38 +- .../Dialect/Transforms/LoweringPrepare.cpp | 16 +- .../CIR/Dialect/Transforms/MergeCleanups.cpp | 2 +- .../lib/CIR/Dialect/Transforms/SCFPrepare.cpp | 2 +- .../lib/CIR/Dialect/Transforms/StdHelpers.cpp | 2 +- .../Transforms/TargetLowering/ABIInfoImpl.cpp | 2 +- .../TargetLowering/ItaniumCXXABI.cpp | 2 +- .../TargetLowering/LowerFunction.cpp | 2 +- .../TargetLowering/Targets/AArch64.cpp | 2 +- .../Targets/LoweringPrepareAArch64CXXABI.cpp | 10 +- .../Targets/LoweringPrepareItaniumCXXABI.cpp | 2 +- .../Transforms/TargetLowering/Targets/X86.cpp | 2 +- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 343 +++++++++--------- .../Lowering/DirectToLLVM/LowerToLLVMIR.cpp | 10 +- .../Lowering/DirectToLLVM/LoweringHelpers.h | 4 +- .../ThroughMLIR/LowerCIRLoopToSCF.cpp | 4 +- .../Lowering/ThroughMLIR/LowerCIRToMLIR.cpp | 89 ++--- .../Lowering/ThroughMLIR/LowerToMLIRHelpers.h | 4 +- 56 files changed, 729 insertions(+), 683 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index 9201f0859be0..b9ad798d27d0 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -133,7 +133,7 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { } mlir::Value createShift(mlir::Value lhs, unsigned bits, bool isShiftLeft) { - auto width = lhs.getType().dyn_cast().getWidth();

Resolves issue #498 - Add a `cir.const_vec`, simlar to `cir.const_array` and `cir.const_struct` Create a new kind of attribute, `cir::ConstVectorAttr` in the code or `#cir.const_vector` in the assembly, which represents a compile-time value of a `cir::VectorType`. The values for the elements within the vector are stored as attributes within an `mlir::ArrayAttr`. When doing CodeGen for a prvalue of vector type, try to represent it as `cir.const #cir.const_vector` first. If that fails, most likely because some of the elements are not compile-time values, fall back to the existing code that uses a `cir.vec.create` operation. When lowering directly to LLVM IR, lower `cir.const #cir.const_vector` as `llvm.mlir.constant(dense<[...]> : _type_) : _type_`. When lowering through other MLIR dialects, lower `cir.const #cir.const_vector` as `arith.constant dense<[...]> : _type_`. No new tests were added, but the expected results of the existing tests that use vector constants were updated. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 31 +++++++ clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 7 +- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 44 +++++++++- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 81 +++++++++++++++++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 36 +++++++++ .../Lowering/ThroughMLIR/LowerCIRToMLIR.cpp | 57 +++++++++---- clang/test/CIR/CodeGen/vectype-ext.cpp | 19 ++--- clang/test/CIR/CodeGen/vectype.cpp | 10 +-- .../test/CIR/Lowering/ThroughMLIR/vectype.cpp | 16 +--- clang/test/CIR/Lowering/vectype.cpp | 28 +------ 10 files changed, 254 insertions(+), 75 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 0d270a4b59ce..b5cff38517e2 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -146,6 +146,37 @@ def ConstArrayAttr : CIR_Attr<"ConstArray", "const_array", [TypedAttrInterface]> }]; } +//===----------------------------------------------------------------------===// +// ConstVectorAttr +//===----------------------------------------------------------------------===// + +def ConstVectorAttr : CIR_Attr<"ConstVector", "const_vector", + [TypedAttrInterface]> { + let summary = "A constant vector from ArrayAttr"; + let description = [{ + A CIR vector attribute is an array of literals of the specified attribute + types. + }]; + + let parameters = (ins AttributeSelfTypeParameter<"">:$type, + "ArrayAttr":$elts); + + // Define a custom builder for the type; that removes the need to pass in an + // MLIRContext instance, as it can be inferred from the `type`. + let builders = [ + AttrBuilderWithInferredContext<(ins "mlir::cir::VectorType":$type, + "ArrayAttr":$elts), [{ + return $_get(type.getContext(), type, elts); + }]> + ]; + + // Printing and parsing available in CIRDialect.cpp + let hasCustomAssemblyFormat = 1; + + // Enable verifier. + let genVerifyDecl = 1; +} + //===----------------------------------------------------------------------===// // ConstStructAttr //===----------------------------------------------------------------------===// diff --git a/clang/lib/CIR/CodeGen/CIRGenDecl.cpp b/clang/lib/CIR/CodeGen/CIRGenDecl.cpp index 1c43655ced6b..52b36c1fa7ac 100644 --- a/clang/lib/CIR/CodeGen/CIRGenDecl.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenDecl.cpp @@ -66,15 +66,16 @@ CIRGenFunction::buildAutoVarAlloca(const VarDecl &D, if (getLangOpts().OpenMP && openMPLocalAddr.isValid()) { llvm_unreachable("NYI"); } else if (Ty->isConstantSizeType()) { - // If this value is an array or struct with a statically determinable - // constant initializer, there are optimizations we can do. + // If this value is an array, struct, or vector with a statically + // determinable constant initializer, there are optimizations we can do. // // TODO: We should constant-evaluate the initializer of any variable, // as long as it is initialized by a constant expression.

Before this patch, for the expression `-x` where `x` is a fp16 value, CIRGen emits the code like the following: ```mlir %0 = cir.cast float_to_float %x : !cir.f16 -> !cir.float %1 = cir.cast float_to_float %0 : !cir.float -> !cir.f16 %2 = cir.unary minus %1 : !cir.fp16 ``` The expected CIRGen should instead be: ```mlir %0 = cir.cast float_to_float %x : !cir.f16 -> !cir.float %1 = cir.unary minus %0 : !cir.float %2 = cir.cast float_to_float %1 : !cir.float -> !cir.f16 ``` This PR fixes this issue. --- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 42 +++++++++++++--------- clang/test/CIR/CodeGen/bf16-ops.c | 8 ++--- clang/test/CIR/CodeGen/fp16-ops.c | 8 ++--- 3 files changed, 34 insertions(+), 24 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp index 019705c247d0..c7289d62aa14 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp @@ -604,37 +604,47 @@ class ScalarExprEmitter : public StmtVisitor { : PromotionType; auto result = VisitPlus(E, promotionTy); if (result && !promotionTy.isNull()) - result = buildUnPromotedValue(result, E->getType()); - return buildUnaryOp(E, mlir::cir::UnaryOpKind::Plus, result); + return buildUnPromotedValue(result, E->getType()); + return result; } - mlir::Value VisitPlus(const UnaryOperator *E, QualType PromotionType) { + mlir::Value VisitPlus(const UnaryOperator *E, + QualType PromotionType = QualType()) { // This differs from gcc, though, most likely due to a bug in gcc.

This is needed for CIR OG to know FuncOP is not declaration anymore, thus giving shouldAssumeDsoLocal another run to make dso_local right. A couple of notes about test; 1. having to changed driver.c, because in terms of dso_local for func, masOS is different from other targets as even in OG, as [macOS is !isOSBinFormatELF()](https://github.com/llvm/clangir/blob/f78f9a55e7cd6b9e350556e35097616676cf1f3e/clang/lib/CodeGen/CodeGenModule.cpp#L1599), thus even OG doesn't set dso_local for its functions. 3. most of functions in existing tests still not getting dso_local in LLVM yet because they fall into case of [(RM != llvm::Reloc::Static && !LOpts.PIE) ](https://github.com/llvm/clangir/blob/f78f9a55e7cd6b9e350556e35097616676cf1f3e/clang/lib/CodeGen/CodeGenModule.cpp#L1605C6-L1605C47), which is more complicated to implement as we need to get canBenefitFromLocalAlias right. So I treated it as a missing feature and default it to false. We gonna leave it to another PR to address. In this PR, I just added additional test with -fpie option to my test so we get dso_local for functions without having to deal with this case. Next 2 PRs: PR1. call setNonAliasAttributes in buildGlobalVarDefinition, after initialization for GlobalOP is found, similar to FuncOp. didn't to it in this PR as there are many more test cases needed to be fixed/added for this case.

It ports an upstream optimization "exact cast" to CIR. The basic idea of exact cast is when `dynamic_cast` to a final class, we don't have to call into the runtime -- we could just check if the dynamic type of the source object is exactly the destination type by quickly comparing the vtable pointers. To give a concrete example of this optimization: ```cpp struct Base { virtual ~Base(); }; struct Derived final : Base {}; Derived *test(Base *src) { return dynamic_cast(src); } ``` Without the optimization, we have to call the runtime function `__dynamic_cast` to do the heavy and slow type check. After enabling the optimization, we could quickly carry out the runtime type check by inline checking whether the vtable ptr of `src` points to the vtable of `Derived`. This PR also fixes a bug in existing dynamic_cast CIRGen code. The bug mistakenly removes the insertion point after emitting a call to bad_cast, causing the CIRGen of any follow up statements to crash. --- clang/lib/CIR/CodeGen/CIRGenCXXABI.h | 2 +- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 8 +- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 169 ++++++++++++++++-- clang/test/CIR/CodeGen/dynamic-cast-exact.cpp | 87 +++++++++ 4 files changed, 250 insertions(+), 16 deletions(-) create mode 100644 clang/test/CIR/CodeGen/dynamic-cast-exact.cpp diff --git a/clang/lib/CIR/CodeGen/CIRGenCXXABI.h b/clang/lib/CIR/CodeGen/CIRGenCXXABI.h index 5f6ea8c1d852..e29f843d235f 100644 --- a/clang/lib/CIR/CodeGen/CIRGenCXXABI.h +++ b/clang/lib/CIR/CodeGen/CIRGenCXXABI.h @@ -309,7 +309,7 @@ class CIRGenCXXABI { QualType SrcRecordTy, QualType DestRecordTy, mlir::cir::PointerType DestCIRTy, - bool isRefCast, mlir::Value Src) = 0; + bool isRefCast, Address Src) = 0; }; /// Creates and Itanium-family ABI diff --git a/clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp b/clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp index cf18593ff711..e3ce7adb0be7 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp @@ -1094,9 +1094,14 @@ static mlir::Value buildDynamicCastToNull(CIRGenFunction &CGF, mlir::Value NullPtrValue = CGF.getBuilder().getNullPtr(DestCIRTy, Loc); if (!DestTy->isPointerType()) { + auto *CurrentRegion = CGF.getBuilder().getBlock()->getParent(); /// C++ [expr.dynamic.cast]p9: /// A failed cast to reference type throws std::bad_cast CGF.CGM.getCXXABI().buildBadCastCall(CGF, Loc); + + // The call to bad_cast will terminate the current block.

The only change we need to make here is adding a new type converter to the LLVM lowering pass. The majority of this PR is tests that check the generated LLVM IR. Later I'll add another separate PR that adds LLVM lowering support for the `__bf16` type. This PR is already big enough. --- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 3 + .../CIR/CodeGen/{fp16-ops.c => float16-ops.c} | 654 +++++++++++++++++- 2 files changed, 655 insertions(+), 2 deletions(-) rename clang/test/CIR/CodeGen/{fp16-ops.c => float16-ops.c} (65%) diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index 7fa50766f737..6818e1bf5c2e 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -3419,6 +3419,9 @@ void prepareTypeConverter(mlir::LLVMTypeConverter &converter, converter.addConversion([&](mlir::cir::LongDoubleType type) -> mlir::Type { return converter.convertType(type.getUnderlying());

It also contains support for its CIRGen. In detail, this patch adds the following CIR types, ops, and attributes: - The `!cir.complex` type is added to model the `_Complex` type in C. This type is parameterized with the type of the components of the complex number, which must be either an integer type or a floating-point type. - ~The `#cir.complex` attribute is added to represent a literal value of `_Complex` type. It is a struct-like attribute that provides the real and imaginary part of the literal `_Complex` value.~ - ~The `#cir.imag` attribute is added to represent a purely imaginary number.~ - The `cir.complex.create` op is added to create a complex value from its real and imaginary parts. - ~The `cir.complex.real` and `cir.complex.imag` op is added to extract the real and imaginary part of a value of `!cir.complex` type, respectively.~ - The `cir.complex.real_ptr` and `cir.complex.imag_ptr` op is added to derive a pointer to the real and imaginary part of a value of `!cir.complex` type, respectively. CIRGen support for some of the fundamental complex number operations is also included. ~Note the implementation diverges from the original clang CodeGen, where expressions of complex types are handled differently from scalars and aggregates. Instead, this patch treats expressions of complex types as scalars, as such expressions can be simply lowered to a CIR value of `!cir.complex` type.~ This PR addresses #445 . --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 29 ++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 84 +++ .../include/clang/CIR/Dialect/IR/CIRTypes.td | 36 +- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 55 +- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 29 +- clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp | 478 ++++++++++++++++++ clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 47 +- clang/lib/CIR/CodeGen/CIRGenFunction.h | 16 + clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenValue.h | 13 +- clang/lib/CIR/CodeGen/CMakeLists.txt | 1 + clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 55 +- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 54 ++ clang/test/CIR/CodeGen/complex.c | 153 ++++++ 16 files changed, 1032 insertions(+), 32 deletions(-) create mode 100644 clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp create mode 100644 clang/test/CIR/CodeGen/complex.c diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index df2231c389a3..e636d59c6539 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -89,6 +89,35 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return getPointerTo(::mlir::cir::VoidType::get(getContext()), langAS);

0f70bca277a592fe7cf7d575242b97fa755c0c6f Mon Sep 17 00:00:00 2001 From: David Olsen Date: Mon, 8 Jul 2024 19:29:15 -0700 Subject: [PATCH 1674/2301] [CIR] Fix for __atomic_compare_exchange weak arg (#721) ClangIR was failing on ``` __atomic_compare_exchange_n(&a, &old, 42, true, 5, 5); ``` The `true` was the problem. It would work with a literal `0` or `1`, but not with a literal `true` or `false`. The bug was in `isCstWeak` in CIRGenAtomic.cpp, which was only looking for an integral constant. It didn't recognize a boolean constant and was falling back on the non-constant path, which isn't implemented yet. Rewrite `isCstWeak` to check for both intergral and boolean constants. --- clang/lib/CIR/CodeGen/CIRGenAtomic.cpp | 27 +++++++++++++++++++------- clang/test/CIR/CodeGen/atomic.cpp | 6 +++--- 2 files changed, 23 insertions(+), 10 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenAtomic.cpp b/clang/lib/CIR/CodeGen/CIRGenAtomic.cpp index 36c2e33de195..4f6567d1fd15 100644 --- a/clang/lib/CIR/CodeGen/CIRGenAtomic.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenAtomic.cpp @@ -348,12 +348,25 @@ static mlir::cir::IntAttr getConstOpIntAttr(mlir::Value v) { return constVal; } -static bool isCstWeak(mlir::Value weakVal, uint64_t &val) { - auto intAttr = getConstOpIntAttr(weakVal); - if (!intAttr) - return false; - val = intAttr.getUInt(); - return true; +// Inspect a value that is the strong/weak flag for a compare-exchange.

The CIR IV users might still CIR operations during lowering forOp. It caused the issue that CIR operation contained SCF.IV as operand which is MLIR integer type instead CIR type. This comment lower CIR load IV_ADDR with ARITH addi SCF.IV, 0 So SCF.IV can be propagated by OpAdaptor when lowering individual IV users. This simplifies the lowering and fixes the issue. The redundant arith.addi can be removed by later MLIR passes. --- .../ThroughMLIR/LowerCIRLoopToSCF.cpp | 28 +-- clang/test/CIR/Lowering/ThroughMLIR/for.cir | 237 ------------------ clang/test/CIR/Lowering/ThroughMLIR/for.cpp | 103 ++++++++ 3 files changed, 111 insertions(+), 257 deletions(-) delete mode 100644 clang/test/CIR/Lowering/ThroughMLIR/for.cir create mode 100644 clang/test/CIR/Lowering/ThroughMLIR/for.cpp diff --git a/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRLoopToSCF.cpp b/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRLoopToSCF.cpp index f308076ef62c..4aee2701c86a 100644 --- a/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRLoopToSCF.cpp +++ b/clang/lib/CIR/Lowering/ThroughMLIR/LowerCIRLoopToSCF.cpp @@ -204,19 +204,6 @@ void SCFLoop::analysis() { assert(upperBound && "can't find loop upper bound");

It makes all CIR FP intrinsic ops lower to their corresponding LLVM intrinsics (`fmod` is a special case and it is lowered to the `frem` LLVM instruction). --- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 20 +++ .../Dialect/Transforms/LoweringPrepare.cpp | 71 ----------- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 46 ++++++- .../test/CIR/CodeGen/builtin-floating-point.c | 120 +++++++++--------- .../test/CIR/Lowering/builtin-binary-fp2fp.c | 64 +++++++++- 5 files changed, 184 insertions(+), 137 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index 97a0c08ef3c6..e4c8201d2dca 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -448,6 +448,8 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, case Builtin::BI__builtin_cosf16: case Builtin::BI__builtin_cosl: case Builtin::BI__builtin_cosf128: + assert(getContext().getLangOpts().FastMath && + "cir.cos is only expected under -ffast-math");

I submit this draft PR if someone wants to play with mem2reg right now and to define the next incremental steps if necessary. Briefly, what's important: 1) I used llvm dialect implementation for the inspiration 2) I did not implement interfaces for some of the operations, e.g. for `cir.get_member`, since looks like mem2reg doesn't handle them - it's more about SROA pass. 3) simple tests are added 4) mem2reg is disabled by default, so one need to use it explicitly, with the `-fclangir-mem2reg` option 5) There are a couple bugs fixed in the code . The most important is tablegen for `BranchOp` that assumed same sized operands for branches (it was extremely hard to detect!). Note, that this `mem2reg` implementation work with flat CIR only. First of all, the MLIR's mem2reg knows how to propagate (and remove) memory slots only when we can build a graph of blocks (e.g. dom tree is a bread and butter of mem2reg). Also, given that phi nodes are represents as blocks with arguments in MLIR, there is no chance to transfer control flow and `call` a block from another region (and pass some values as well). The last one is important and has some relation to `canonicalizer` - may be you remember I mentioned this problem once somewhere, when conditional branch verification fails on target block arguments number and branch operands number mismatch. finally, short example to play with: ``` int return_42() { int y = 42; return y; } ``` First, without mem2reg enabled `clang tmp.c -fclangir -emit-llvm -S -o -` : ``` define dso_local i32 @return_42() #0 !dbg !3 { %1 = alloca i32, i64 1, align 4, !dbg !7 %2 = alloca i32, i64 1, align 4, !dbg !8 store i32 42, ptr %2, align 4, !dbg !8 %3 = load i32, ptr %2, align 4, !dbg !9 store i32 %3, ptr %1, align 4, !dbg !10 %4 = load i32, ptr %1, align 4, !dbg !10 ret i32 %4, !dbg !10 } ``` and with mem2reg enabled `clang tmp.c -fclangir -fclangir-mem2reg -emit-llvm -S -o -`: ``` define dso_local i32 @return_42() #0 !dbg !3 { ret i32 42, !dbg !7 } ``` So. What do you think? Which steps do you expect me to perform? I can try to split this PR into parts and add interfaces one-by-one, but I'n not sure the tests will work without all of them implemented. --- clang/include/clang/CIR/CIRToCIRPasses.h | 3 +- .../include/clang/CIR/Dialect/IR/CIRDialect.h | 1 + clang/include/clang/CIR/Dialect/IR/CIROps.td | 34 ++- clang/include/clang/Driver/Options.td | 4 + .../include/clang/Frontend/FrontendOptions.h | 3 + clang/lib/CIR/CodeGen/CIRPasses.cpp | 12 +- clang/lib/CIR/Dialect/IR/CIRMemorySlot.cpp | 184 +++++++++++++++++ clang/lib/CIR/Dialect/IR/CMakeLists.txt | 1 + clang/lib/CIR/FrontendAction/CIRGenAction.cpp | 3 +- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 17 +- clang/lib/Driver/ToolChains/Clang.cpp | 3 + clang/lib/Frontend/CompilerInvocation.cpp | 3 + clang/test/CIR/Transforms/mem2reg.c | 195 ++++++++++++++++++ clang/test/CIR/Transforms/mem2reg.cir | 31 +++ 14 files changed, 478 insertions(+), 16 deletions(-) create mode 100644 clang/lib/CIR/Dialect/IR/CIRMemorySlot.cpp create mode 100644 clang/test/CIR/Transforms/mem2reg.c create mode 100644 clang/test/CIR/Transforms/mem2reg.cir diff --git a/clang/include/clang/CIR/CIRToCIRPasses.h b/clang/include/clang/CIR/CIRToCIRPasses.h index b70806ddb77e..a88fba7a76e3 100644 --- a/clang/include/clang/CIR/CIRToCIRPasses.h +++ b/clang/include/clang/CIR/CIRToCIRPasses.h @@ -34,7 +34,8 @@ mlir::LogicalResult runCIRToCIRPasses( llvm::StringRef lifetimeOpts, bool enableIdiomRecognizer, llvm::StringRef idiomRecognizerOpts, bool enableLibOpt, llvm::StringRef libOptOpts, std::string &passOptParsingFailure, - bool flattenCIR, bool emitMLIR, bool enableCallConvLowering);

Specifically, CIRGen for the following operations on complex numbers are added: - Binary arithmetic operations: add, sub, mul, and div. - ~Unary arithmetic operations: plus, minus, and conjugate.~ A new operation `cir.complex.binop` is added to represent binary operations on complex number operands. The new operation contains complex-number-specific attributes for correct lowering to LLVM IR. ~I'll add LLVM IR lowering in later PRs as this PR is already large enough.~ This PR also includes LLVM IR lowering support. It introduces two new operations `cir.complex.real` and `cir.complex.imag` to aid for LLVM IR lowering. These two new operations extract the real and imaginary part of a complex value, which is useful during lowering prepare, during which phase the complex arithmetic operations are broken down to a series of scalar arithmetic operations on the real and imaginary parts of the complex operands. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 72 ++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 118 +++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 7 - clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp | 401 ++++++++++- clang/lib/CIR/CodeGen/CIRGenFunction.h | 10 + clang/lib/CIR/CodeGen/CIRGenValue.h | 6 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 26 + .../Dialect/Transforms/LoweringPrepare.cpp | 330 ++++++++- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 39 +- clang/test/CIR/CodeGen/complex-arithmetic.c | 647 ++++++++++++++++++ 11 files changed, 1637 insertions(+), 25 deletions(-) create mode 100644 clang/test/CIR/CodeGen/complex-arithmetic.c diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index e636d59c6539..d6f6ce972f41 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -145,6 +145,15 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return create(loc, getBoolTy(), kind, lhs, rhs);

This PR changes its type to `mlir::cir::AddressSpaceAttr` to better fit the need of CIRGen. In [D32248: CodeGen: Cast alloca to expected address space](https://reviews.llvm.org/D32248), the author explained why these AS parameters are not used: > This is just the default implementation. The idea is that targets that need to do something more complex on a particular conversion — e.g. to make sure that null pointers are translated correctly when they have different bit-patterns — can easily do so. Further more, I'm confident that the CIR AS is also capable of providing custom behaviors like above for those targets. --- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 5 +++-- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 6 ++++-- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 7 +++++-- clang/lib/CIR/CodeGen/TargetInfo.cpp | 5 +++-- clang/lib/CIR/CodeGen/TargetInfo.h | 9 +++++---- 5 files changed, 20 insertions(+), 12 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index e4c8201d2dca..441c56d9aefb 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -1055,8 +1055,9 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, // the AST level this is handled within CreateTempAlloca et al., but for the // builtin / dynamic alloca we have to handle it here. assert(!MissingFeatures::addressSpace());

Add comdat attribute as an optional attribute to CIR GlobalOp and FuncOp, they are of the enum ComdatSelection type because it contains all information we need. The [llvm/include/llvm/IR/Comdat.h](https://github.com/llvm/clangir/blob/4ea2ec38638391b964e88b77f926e0892b350e04/llvm/include/llvm/IR/Comdat.h#L33) has Comdat with selectionKind and its name, add users which are set of pointers to GlobalObjects sharing the same name. The name is always the name of global object (in CIR context, the GlobalOp or FuncOp), so we don't need it. And the user set can always be collected when a transformation looks up symbol table of the module, thus not really necessary. Plus, it's not good for CIR to keep a set of pointers. 2. Thanks to comdat support, and adding call sites of setComdat similar to what was in OG, we are able to implement canBenefitFromLocalAlias as similar as possible to [GlobalValue::canBenefitFromLocalAlias() ](https://github.com/llvm/clangir/blob/4ea2ec38638391b964e88b77f926e0892b350e04/llvm/lib/IR/Globals.cpp#L112) and this enable us to complete dso_local work by correctly setting dso_local for functions. 3. I took back printing of dsolocal attribute of CIR, as I would fix 128+ test cases instead of 36-37 of tests (mostly adding dso_local to function prototype line in LLVM check) in this PR. printing dsolocal attribute is not really necessary as llvm IR would verify it for us. 4. LLVM lowering of Comdat for GlobalOp Things left to next/future PR 1. I'd like to extend setComdat to other parts of CG like Vtable, etc. 2.

1712/2301] [CIR][CodeGen][LowerToLLVM] End-to-end implementation of `offload_*` cases for OpenCL with SPIR-V target (#724) This PR implements `offload_*` cases discussed in [this thread](https://discourse.llvm.org/t/rfc-clangir-unified-address-space-design-in-clangir/79728). * Integrate target-specific CIR-to-LLVM address space map into `TargetLoweringInfo` * CIRGen: Implement these cases in `getValueFromLangAS` * Lowering: Extend the state of type converter with `LowerModule` When frontend provides a new LangAS like `opencl_generic`, it would be processed by CIRGenTypes and `Builder.getPointerTo()` and encoded as `offload_generic`. When we lower CIR to LLVM, * For pointer types without address space attribute, it's mapped to `ptr addrspace(0)` directly * For target cases `target`, it's mapped to `ptr addrspace(x)` * For other defined cases, query the target info with a new virtual method `getTargetAddrSpaceFromCIRAddrSpace`. General targets like X86 and ARM64 map all known cases to 0. For SPIR-V target here, it maps `offload_generic` to `addrspace(4)`. --- clang/include/clang/CIR/MissingFeatures.h | 5 ++- clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 6 +++ .../TargetLowering/TargetLoweringInfo.h | 4 ++ .../TargetLowering/Targets/AArch64.cpp | 15 +++++++ .../TargetLowering/Targets/SPIR.cpp | 19 ++++++++ .../Transforms/TargetLowering/Targets/X86.cpp | 15 +++++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 43 ++++++++++++++----- .../CIR/CodeGen/OpenCL/addrspace-alloca.cl | 10 ++--- clang/test/CIR/CodeGen/OpenCL/spirv-target.cl | 2 - clang/test/CIR/Lowering/address-space.cir | 20 ++++++++- 10 files changed, 119 insertions(+), 20 deletions(-) diff --git a/clang/include/clang/CIR/MissingFeatures.h b/clang/include/clang/CIR/MissingFeatures.h index 48ab598311e8..d67989120562 100644 --- a/clang/include/clang/CIR/MissingFeatures.h +++ b/clang/include/clang/CIR/MissingFeatures.h @@ -161,7 +161,6 @@ struct MissingFeatures { static bool constantFoldsToSimpleInteger() { return false; } static bool checkFunctionCallABI() { return false; } static bool zeroInitializer() { return false; } - static bool targetLoweringInfoAddressSpaceMap() { return false; } static bool targetCodeGenInfoIsProtoCallVariadic() { return false; } static bool targetCodeGenInfoGetNullPointer() { return false; } static bool operandBundles() { return false; } @@ -277,6 +276,10 @@ struct MissingFeatures { static bool returnValueDominatingStoreOptmiization() { return false; } // Globals (vars and functions) may have attributes that are target depedent. static bool setTargetAttributes() { return false; } + + // CIR modules parsed from text form may not carry the triple or data layout + // specs.

For x86_64, this is a bit of an odd case. In the orignal codegen bools are represented as i8 everywhere, except for function arguments/return values. In CIR, we don't allow i1 types, so bools are still represented as `cir.bool` when in functions. However, when lowering to LLVM Dialect, we need to ensure bools will be converted to i1 when in function's argument/return values. --- clang/include/clang/CIR/ABIArgInfo.h | 3 ++- .../Transforms/TargetLowering/CIRLowerContext.cpp | 12 +++++++++++- .../Transforms/TargetLowering/LowerFunction.cpp | 15 ++++----------- .../Transforms/TargetLowering/LowerTypes.cpp | 2 +- .../Transforms/TargetLowering/Targets/X86.cpp | 5 ++++- .../aarch64/aarch64-call-conv-lowering-pass.cpp | 6 ++++++ .../x86_64/x86_64-call-conv-lowering-pass.cpp | 12 ++++++++++++ 7 files changed, 40 insertions(+), 15 deletions(-) diff --git a/clang/include/clang/CIR/ABIArgInfo.h b/clang/include/clang/CIR/ABIArgInfo.h index 78127230a7ce..d330b2c3e24d 100644 --- a/clang/include/clang/CIR/ABIArgInfo.h +++ b/clang/include/clang/CIR/ABIArgInfo.h @@ -185,7 +185,8 @@ class ABIArgInfo { } static ABIArgInfo getExtend(mlir::Type Ty, mlir::Type T = nullptr) { // NOTE(cir): The original can apply this method on both integers and - // enumerations, but in CIR, these two types are one and the same. + // enumerations, but in CIR, these two types are one and the same.

[CIR][CodeGen][Lowering] Better handling of alloca address space with unified AS (#682) `TargetCodeGenInfo::getASTAllocaAddressSpace` is a bad design because it requires the targets return `LangAS`, which enforce the targets to consider which languages could be their upstream and unnecessarily complicate the target info. Unified AS in CIR is a better abstraction level for this kind of target info. Apart from that, the languages also has some requirements on the result address space of alloca. ```cpp void func() { int x; // Here, the AS of pointer `&x` is the alloca AS defined by the language. } ``` When we have inconsistency between the alloca AS defined by the language and the one from target info, we have to perform `addrspacecast` from the target one to the language one. This PR includes * New method `CGM.getLangTempAllocaAddressSpace` which explicitly specifies the alloca address space defined by languages. It replaces the vague `LangAS::Default` in the AS comparisons from OG CodeGen. * Replace `getASTAllocaAddressSpace` with `getCIRAllocaAddressSpace`, which returns CIR unified AS. * Also use `getCIRAllocaAddressSpace` as the result address space of `buildAlloca`. * Fix the lowering of `cir.alloca` operation to be address-space-aware. We don't perform any `addrspacecast` in this PR, i.e. all the related code paths still remain NYI and it's fine. That's because we don't even have a `(language, target)` pair holding the inconsistency. After these changes, in the previous OpenCL testcases we will see all the alloca pointers turning into private AS, without any `addrspacecast`. --- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 9 +++++++-- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 12 +++++++++++- clang/lib/CIR/CodeGen/CIRGenModule.h | 6 ++++++ clang/lib/CIR/CodeGen/CIRGenTypeCache.h | 12 ++++-------- clang/lib/CIR/CodeGen/TargetInfo.cpp | 6 ++++++ clang/lib/CIR/CodeGen/TargetInfo.h | 8 +++++--- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 3 ++- .../test/CIR/CodeGen/OpenCL/addrspace-alloca.cl | 16 ++++++++++++---- 9 files changed, 54 insertions(+), 20 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index a16148a21986..7970be0eccf7 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -1100,7 +1100,7 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, // the AST level this is handled within CreateTempAlloca et al., but for the // builtin / dynamic alloca we have to handle it here. assert(!MissingFeatures::addressSpace()); - auto AAS = builder.getAddrSpaceAttr(getASTAllocaAddressSpace()); + auto AAS = getCIRAllocaAddressSpace(); auto EAS = builder.getAddrSpaceAttr( E->getType()->getPointeeType().getAddressSpace()); if (EAS != AAS) { diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index d6045548bfd6..d91c8603b3d7 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -2756,7 +2756,10 @@ mlir::Value CIRGenFunction::buildAlloca(StringRef name, mlir::Type ty, mlir::Location loc, CharUnits alignment, mlir::OpBuilder::InsertPoint ip, mlir::Value arraySize) { - auto localVarPtrTy = mlir::cir::PointerType::get(builder.getContext(), ty); + // CIR uses its own alloca AS rather than follow the target data layout like + // original CodeGen.

Also, the metadata is stored by `Array` with proper verification on it. See the tablegen doc string for details. This is in order to * keep it side-by-side with `cl.kernel_metadata`. * still emit metadata when kernel has an *empty* arg list (see the test `kernel-arg-meatadata.cl`). * avoid horrors of repeating the long name `cir.cl.kernel_arg_metadata` for `numArgs` times.

The idea is to have a pass for the redundant operations removal/update. Right now two pattern implemented, both related to the redundant `bool` operations. First pattern removes redundant casts from `bool` to `int` and back that for some reasons appear in the code. Second pattern removes sequential unary not operations (`!!`) . For example, the code from the test is expanded from the simple check that is common for C code: ``` #define CHECK_PTR(ptr) \ do { \ if (__builtin_expect((!!((ptr) == 0)), 0))\ return -42; \ } while(0) ``` I mark this PR as a draft for the following reasons: 1) I have no idea if it's useful for the community 2) There is a test fail - unfortunately current pattern rewriter run DCE underneath the hood and looks like we can't workaround it. It's enough just to add an operation to the list - in this case `UnaryOp` - and call `applyOpPatternsAndFold`. I could rewrite a test a little in order to make everything non dead or implement a simple fix point algorithm for the particular task (I would do the former). --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 1 + clang/include/clang/CIR/Dialect/Passes.h | 2 +- clang/include/clang/CIR/Dialect/Passes.td | 22 +++-- clang/lib/CIR/CodeGen/CIRPasses.cpp | 4 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 94 +++++++++++++++---- .../{MergeCleanups.cpp => CIRSimplify.cpp} | 16 ++-- .../lib/CIR/Dialect/Transforms/CMakeLists.txt | 2 +- clang/test/CIR/CodeGen/unary.cpp | 30 +++--- clang/test/CIR/Transforms/merge-cleanups.cir | 2 +- clang/test/CIR/Transforms/simpl.c | 38 ++++++++ clang/test/CIR/Transforms/simpl.cir | 50 ++++++++++ clang/test/CIR/mlirprint.c | 8 +- clang/tools/cir-opt/cir-opt.cpp | 2 +- 13 files changed, 214 insertions(+), 57 deletions(-) rename clang/lib/CIR/Dialect/Transforms/{MergeCleanups.cpp => CIRSimplify.cpp} (91%) create mode 100644 clang/test/CIR/Transforms/simpl.c create mode 100644 clang/test/CIR/Transforms/simpl.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 585cbfcd0ff3..6d4abb8897c8 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -991,6 +991,7 @@ def UnaryOp : CIR_Op<"unary", [Pure, SameOperandsAndResultType]> { }]; let hasVerifier = 1; + let hasFolder = 1; } //===----------------------------------------------------------------------===// diff --git a/clang/include/clang/CIR/Dialect/Passes.h b/clang/include/clang/CIR/Dialect/Passes.h index de9621fc8bb6..116966d52f15 100644 --- a/clang/include/clang/CIR/Dialect/Passes.h +++ b/clang/include/clang/CIR/Dialect/Passes.h @@ -26,7 +26,7 @@ std::unique_ptr createLifetimeCheckPass(ArrayRef remark, ArrayRef hist, unsigned hist_limit, clang::ASTContext *astCtx); -std::unique_ptr createMergeCleanupsPass(); +std::unique_ptr createCIRSimplifyPass(); std::unique_ptr createDropASTPass(); std::unique_ptr createSCFPreparePass(); std::unique_ptr createLoweringPreparePass(); diff --git a/clang/include/clang/CIR/Dialect/Passes.td b/clang/include/clang/CIR/Dialect/Passes.td index c43812ff1032..536e35b9e0dc 100644 --- a/clang/include/clang/CIR/Dialect/Passes.td +++ b/clang/include/clang/CIR/Dialect/Passes.td @@ -11,14 +11,24 @@ include "mlir/Pass/PassBase.td" -def MergeCleanups : Pass<"cir-merge-cleanups"> { - let summary = "Remove unnecessary branches to cleanup blocks"; +def CIRSimplify : Pass<"cir-simplify"> { + let summary = "Performs CIR simplification"; let description = [{ - Canonicalize pass is too aggressive for CIR when the pipeline is - used for C/C++ analysis.

CIRGen and LLVM IR support for these new cast variants are also included. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 27 ++- clang/include/clang/CIR/Dialect/IR/CIROps.td | 28 ++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 46 ---- clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp | 47 +++- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 36 ++- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 112 +++++++++- .../Dialect/Transforms/LoweringPrepare.cpp | 140 +++++++++++- clang/test/CIR/CodeGen/complex-cast.c | 205 ++++++++++++++++++ 8 files changed, 575 insertions(+), 66 deletions(-) create mode 100644 clang/test/CIR/CodeGen/complex-cast.c diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index 4208aa5aaed3..b327645d1958 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -59,6 +59,22 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return create(loc, attr.getType(), attr);

For example, when compiling OpenCL kernels to x86-64 target, the kernel should still use SPIR-V's ABIInfo. As we haven't implemented SPIR-V ABI handling for complex constructs, there should be no functional changes. There is a test for this logic in OG CodeGen: `clang/test/CodeGenOpenCL/kernels-have-spir-cc-by-default.cl`. It mainly involves structs, which is beyond the progress of CIR ABI stuff. --- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 15 ++++++++++----- clang/lib/CIR/CodeGen/TargetInfo.cpp | 10 ++++++++++ clang/lib/CIR/CodeGen/TargetInfo.h | 2 ++ 3 files changed, 22 insertions(+), 5 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenTypes.cpp b/clang/lib/CIR/CodeGen/CIRGenTypes.cpp index 66a0c7c6d3ac..541e15a0930e 100644 --- a/clang/lib/CIR/CodeGen/CIRGenTypes.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenTypes.cpp @@ -783,11 +783,16 @@ const CIRGenFunctionInfo &CIRGenTypes::arrangeCIRFunctionInfo( (void)inserted; assert(inserted && "Recursively being processed?"); - // Compute ABI inforamtion. - assert(info.getCC() != clang::CallingConv::CC_SpirFunction && "NYI"); - assert(info.getCC() != CC_Swift && info.getCC() != CC_SwiftAsync && - "Swift NYI"); - getABIInfo().computeInfo(*FI); + // Compute ABI information. + if (CC == mlir::cir::CallingConv::SpirKernel) { + // Force target independent argument handling for the host visible + // kernel functions. + computeSPIRKernelABIInfo(CGM, *FI); + } else if (info.getCC() == CC_Swift || info.getCC() == CC_SwiftAsync) { + llvm_unreachable("Swift NYI"); + } else { + getABIInfo().computeInfo(*FI); + } // Loop over all of the computed argument and return value info.

The same asm format in pointer type is used: ``` cir.global external addrspace(offload_global) @addrspace1 = #cir.int<1> : !s32i ``` The parsing and printing helper is extracted into a common function to be reused by both `GlobalOp` and `PointerType` with two custom format proxy to it. That's because the signature of ODS generated method differs from the one for PointerType. Lowering to LLVM IR and CIRGen will come sequentially. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 3 +++ clang/include/clang/CIR/Dialect/IR/CIRTypes.h | 5 +++++ clang/lib/CIR/CodeGen/CIRGenBuilder.h | 12 ++++++++---- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 14 ++++++++++++++ clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 18 ++++++++++++++---- clang/test/CIR/IR/global.cir | 10 +++++++++- 6 files changed, 53 insertions(+), 9 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 78da99a65bfe..b2924d1f422b 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2157,6 +2157,7 @@ def GlobalOp : CIR_Op<"global", OptionalAttr:$sym_visibility, TypeAttr:$sym_type, Arg:$linkage, + OptionalAttr:$addr_space, OptionalAttr:$tls_model, // Note this can also be a FlatSymbolRefAttr OptionalAttr:$initial_value, @@ -2175,6 +2176,7 @@ def GlobalOp : CIR_Op<"global", (`comdat` $comdat^)?

Also added some tests. The generated LLVM code is most similar to OG's llvm code, 3 interesting differences: 1. CIR introduced scope, thus extra branch 2. OG' has comdat for _ZSt1fIiEvSt16initializer_listIT_E function, but we haven't implemented FuncOP's comdat yet. I'll probably try to add it in another PR, but it's not in the scope of this PR. 3. When defining initialized_list type, OG prefers generic type like %"class.std::initializer_list" = type { ptr, ptr }, but CIR prefers instantiated like "%"class.std::initializer_list" = type { ptr, ptr }" --- clang/lib/CIR/CodeGen/CIRGenBuilder.cpp | 68 +++++++++++++++ clang/lib/CIR/CodeGen/CIRGenBuilder.h | 31 +++---- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 51 ++---------- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 60 +++++++++++++- clang/lib/CIR/CodeGen/CMakeLists.txt | 1 + clang/test/CIR/CodeGen/initlist-ptr-ptr.cpp | 82 +++++++++++++++++++ .../CIR/CodeGen/initlist-ptr-unsigned.cpp | 64 +++++++++++++++ 7 files changed, 297 insertions(+), 60 deletions(-) create mode 100644 clang/lib/CIR/CodeGen/CIRGenBuilder.cpp create mode 100644 clang/test/CIR/CodeGen/initlist-ptr-ptr.cpp create mode 100644 clang/test/CIR/CodeGen/initlist-ptr-unsigned.cpp diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.cpp b/clang/lib/CIR/CodeGen/CIRGenBuilder.cpp new file mode 100644 index 000000000000..cc2a3aee0ab4 --- /dev/null +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.cpp @@ -0,0 +1,68 @@ +//===-- CIRGenBuilder.cpp - CIRBuilder implementation ---------------------===// +// +// Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. +// See https://llvm.org/LICENSE.txt for license information. +// SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception +// +//===----------------------------------------------------------------------===// +#include "CIRGenBuilder.h" + +namespace cir { + +mlir::Value CIRGenBuilderTy::maybeBuildArrayDecay(mlir::Location loc, + mlir::Value arrayPtr, + mlir::Type eltTy) { + auto arrayPtrTy = + ::mlir::dyn_cast<::mlir::cir::PointerType>(arrayPtr.getType()); + assert(arrayPtrTy && "expected pointer type"); + auto arrayTy = + ::mlir::dyn_cast<::mlir::cir::ArrayType>(arrayPtrTy.getPointee()); + + if (arrayTy) { + mlir::cir::PointerType flatPtrTy = + mlir::cir::PointerType::get(getContext(), arrayTy.getEltType()); + return create( + loc, flatPtrTy, mlir::cir::CastKind::array_to_ptrdecay, arrayPtr); + } + + assert(arrayPtrTy.getPointee() == eltTy && + "flat pointee type must match original array element type"); + return arrayPtr; +} + +mlir::Value CIRGenBuilderTy::getArrayElement(mlir::Location arrayLocBegin, + mlir::Location arrayLocEnd, + mlir::Value arrayPtr, + mlir::Type eltTy, mlir::Value idx, + bool shouldDecay) { + mlir::Value basePtr = arrayPtr; + if (shouldDecay) + basePtr = maybeBuildArrayDecay(arrayLocBegin, arrayPtr, eltTy); + mlir::Type flatPtrTy = basePtr.getType(); + return create(arrayLocEnd, flatPtrTy, basePtr, idx); +} + +mlir::cir::ConstantOp CIRGenBuilderTy::getConstInt(mlir::Location loc, + llvm::APSInt intVal) { + bool isSigned = intVal.isSigned(); + auto width = intVal.getBitWidth(); + mlir::cir::IntType t = isSigned ?

Similarily, some targets may want to use special address space for global variables. So a per-language + per-target hook is needed to provide this customization point. In the LLVM CodeGen, it's the helper method `getGlobalVarAddressSpace` that takes on the role. For OpenCL C + SPIR-V combination, OpenCL C converts the address space qualifier to corresponding LangAS, but SPIR-V does not require any action. This PR implements `global` qualifier in OpenCL C, but does not include `constant` qualifier. Although the modified part works for `constant`, CIRGen is not yet able to set constant attribute for global ops (there is a TODO line). Static variable decl and `local` qualifier work in a similar way and come in later patches. --- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 7 +-- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 62 +++++++++++++++++++------ clang/lib/CIR/CodeGen/CIRGenModule.h | 11 +++++ clang/lib/CIR/CodeGen/TargetInfo.cpp | 9 ++++ clang/lib/CIR/CodeGen/TargetInfo.h | 7 +++ clang/test/CIR/CodeGen/OpenCL/global.cl | 23 +++++++++ 7 files changed, 104 insertions(+), 19 deletions(-) create mode 100644 clang/test/CIR/CodeGen/OpenCL/global.cl diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.h b/clang/lib/CIR/CodeGen/CIRGenBuilder.h index 385f18df0ee0..85c8b5aa2bea 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuilder.h +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.h @@ -674,9 +674,10 @@ class CIRGenBuilderTy : public CIRBaseBuilderTy { mlir::Value createGetGlobal(mlir::cir::GlobalOp global, bool threadLocal = false) { - return create(global.getLoc(), - getPointerTo(global.getSymType()), - global.getName(), threadLocal);

In order to support it, this PR unblocks code paths related to OpenCL static declarations in `CIRGenDecl.cpp`. Following the approach of LLVM CodeGen, a new class `CIRGenOpenCLRuntime` is added to handle the language hook of creating `local`-qualified variables. The default behavior of this hook is quite simple. It forwards the call to `CGF.buildStaticVarDecl`. So in CIR, the OpenCL local memory representation is equivalent to the one defined by SPIR-LLVM convention: a `cir.global` with `addrspace(local)` and *without initializer*, which corresponds to LLVM `undef` initializer. See check lines in test for more details. A `static global`-qualified variable is also added in the test to exercise the static code path itself. --- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 17 +++---- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 4 ++ clang/lib/CIR/CodeGen/CIRGenModule.h | 14 ++++++ clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.cpp | 29 ++++++++++++ clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.h | 46 +++++++++++++++++++ clang/lib/CIR/CodeGen/CMakeLists.txt | 1 + .../test/CIR/CodeGen/OpenCL/static-vardecl.cl | 24 ++++++++++ 7 files changed, 127 insertions(+), 8 deletions(-) create mode 100644 clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.cpp create mode 100644 clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.h create mode 100644 clang/test/CIR/CodeGen/OpenCL/static-vardecl.cl diff --git a/clang/lib/CIR/CodeGen/CIRGenDecl.cpp b/clang/lib/CIR/CodeGen/CIRGenDecl.cpp index 52cf2d182c4a..9a08ccd0d1ff 100644 --- a/clang/lib/CIR/CodeGen/CIRGenDecl.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenDecl.cpp @@ -411,7 +411,7 @@ void CIRGenFunction::buildVarDecl(const VarDecl &D) { } if (D.getType().getAddressSpace() == LangAS::opencl_local) - llvm_unreachable("OpenCL and address space are NYI"); + return CGM.getOpenCLRuntime().buildWorkGroupLocalVarDecl(*this, D); assert(D.hasLocalStorage()); @@ -465,19 +465,19 @@ CIRGenModule::getOrCreateStaticVarDecl(const VarDecl &D, Name = getStaticDeclName(*this, D); mlir::Type LTy = getTypes().convertTypeForMem(Ty); - assert(!MissingFeatures::addressSpace()); + mlir::cir::AddressSpaceAttr AS = + builder.getAddrSpaceAttr(getGlobalVarAddressSpace(&D)); // OpenCL variables in local address space and CUDA shared // variables cannot have an initializer. mlir::Attribute Init = nullptr; - if (Ty.getAddressSpace() == LangAS::opencl_local || - D.hasAttr() || D.hasAttr()) - llvm_unreachable("OpenCL & CUDA are NYI"); - else + if (D.hasAttr() || D.hasAttr()) + llvm_unreachable("CUDA is NYI"); + else if (Ty.getAddressSpace() != LangAS::opencl_local) Init = builder.getZeroInitAttr(getTypes().ConvertType(Ty)); mlir::cir::GlobalOp GV = builder.createVersionedGlobal( - getModule(), getLoc(D.getLocation()), Name, LTy, false, Linkage); + getModule(), getLoc(D.getLocation()), Name, LTy, false, Linkage, AS); // TODO(cir): infer visibility from linkage in global op builder.

It contains the following new types, attributes, and operations: - `!cir.method`, which represents the pointer-to-member-function type. - `#cir.method`, which represents a literal pointer-to-member-function value that points to ~~non-virtual~~ member functions. - ~~`#cir.virtual_method`, which represents a literal pointer-to-member-function value that points to virtual member functions.~~ - ~~`cir.get_method_callee`~~ `cir.get_method`, which resolves a pointer-to-member-function to a function pointer as the callee. See the new test at `clang/test/CIR/CIRGen/pointer-to-member-func.cpp` for how these new CIR stuff works to support pointer-to-member-functions. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 42 +++++++++++ .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 48 ++++++++++++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 54 ++++++++++++++ .../include/clang/CIR/Dialect/IR/CIRTypes.td | 36 ++++++++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 15 ++++ clang/lib/CIR/CodeGen/CIRGenCXXABI.h | 4 + clang/lib/CIR/CodeGen/CIRGenCall.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 47 ++++++++++++ clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 14 +++- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 5 +- clang/lib/CIR/CodeGen/CIRGenFunction.h | 2 + clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 24 ++++++ clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 11 ++- clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 73 +++++++++++++++++++ clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 57 ++++++++++++++- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 33 +++++++++ .../CIR/CodeGen/pointer-to-member-func.cpp | 42 +++++++++++ 18 files changed, 498 insertions(+), 13 deletions(-) create mode 100644 clang/test/CIR/CodeGen/pointer-to-member-func.cpp diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index b327645d1958..d2fc105f502d 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -111,6 +111,10 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return getPointerTo(::mlir::cir::VoidType::get(getContext()), langAS); } + mlir::cir::PointerType getVoidPtrTy(mlir::cir::AddressSpaceAttr cirAS) { + return getPointerTo(::mlir::cir::VoidType::get(getContext()), cirAS); + } + mlir::cir::BoolAttr getCIRBoolAttr(bool state) { return mlir::cir::BoolAttr::get(getContext(), getBoolTy(), state); } @@ -590,6 +594,11 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return create(loc, value); } + mlir::cir::PtrStrideOp createPtrStride(mlir::Location loc, mlir::Value base, + mlir::Value stride) { + return create(loc, base.getType(), base, stride); + } + mlir::cir::CallOp createCallOp(mlir::Location loc, mlir::SymbolRefAttr callee = mlir::SymbolRefAttr(), @@ -678,6 +687,39 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return createTryCallOp(loc, mlir::SymbolRefAttr(), fn_type.getReturnType(), resOperands); } + + struct GetMethodResults { + mlir::Value callee; + mlir::Value adjustedThis; + }; + + GetMethodResults createGetMethod(mlir::Location loc, mlir::Value method, + mlir::Value objectPtr) { + // Build the callee function type. + auto methodFuncTy = + mlir::cast(method.getType()).getMemberFuncTy(); + auto methodFuncInputTypes = methodFuncTy.getInputs(); + + auto objectPtrTy = mlir::cast(objectPtr.getType()); + auto objectPtrAddrSpace = + mlir::cast_if_present( + objectPtrTy.getAddrSpace()); + auto adjustedThisTy = getVoidPtrTy(objectPtrAddrSpace); + + llvm::SmallVector calleeFuncInputTypes{adjustedThisTy}; + calleeFuncInputTypes.insert(calleeFuncInputTypes.end(), + methodFuncInputTypes.begin(), + methodFuncInputTypes.end()); + auto calleeFuncTy = + methodFuncTy.clone(calleeFuncInputTypes, methodFuncTy.getReturnType()); + // TODO(cir): consider the address space of the callee. + assert(!MissingFeatures::addressSpace()); + auto calleeTy = getPointerTo(calleeFuncTy); + + auto op = create(loc, calleeTy, adjustedThisTy, + method, objectPtr); + return {op.getCallee(), op.getAdjustedThis()}; + } }; } // namespace cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index fa3c8004701b..75180131adb3 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -441,6 +441,54 @@ def DataMemberAttr : CIR_Attr<"DataMember", "data_member", }]; } +//===----------------------------------------------------------------------===// +// MethodAttr +//===----------------------------------------------------------------------===// + +def MethodAttr : CIR_Attr<"Method", "method", [TypedAttrInterface]> { + let summary = "Holds a constant pointer-to-member-function value"; + let description = [{ + A method attribute is a literal attribute that represents a constant + pointer-to-member-function value. + + If the member function is a non-virtual function, the `symbol` parameter + gives the global symbol for the non-virtual member function. + + If the member function is a virtual function, the `vtable_offset` parameter + gives the offset of the vtable entry corresponding to the virtual member + function. + + `symbol` and `vtable_offset` cannot be present at the same time.

This was because our alias computation for a StructType did the following: os << "ty_" << structType.getName() `structType.getName()` is a `StringAttr`, and writing a `StringAttr` to an output stream adds double quotes around the actual string [1][2]. These double quotes then get hex-encoded as 22 [3]. We can fix this by writing the actual string value instead. Aliases that would end in a number will now receive a trailing underscore because of MLIR's alias sanitization not allowing a trailing digit [4] (which ironically didn't kick in even though our aliases were always previously ending with a number, which might be a bug in the sanitization logic). Aliases containing other special characters (e.g. `::`) will still be escaped as before. In other words: ``` struct S {}; // before: !ty_22S22 = ... // after: !ty_S = ... struct S1 {}; // before: !ty_22S122 = ... // after: !ty_S1_ = ... struct std::string {}; // before: !ty_22std3A3Astring22 // after: !ty_std3A3Astring ``` I'm not a big fan of the trailing underscore special-case, but I also don't want to touch core MLIR logic, and I think the end result is still nicer than before. The tests were mechanically updated with the following command run inside `clang/test/CIR`, and the same commands can be run to update the tests for any in-flight patches. (These are for GNU sed; for macOS change the `-i` to `-i ''`.) find . -type f | xargs sed -i -E -e 's/ty_22([A-Za-z0-9_$]+[0-9])22/ty_\1_/g' -e 's/ty_22([A-Za-z0-9_$]+)22/ty_\1/g' clang/test/CIR/CodeGen/stmtexpr-init.c needed an additional minor fix to swap the expected order of two type aliases in the CIR output. clang/test/CIR/CodeGen/coro-task.cpp needed some surgery because it was searching for `22` to find the end of a type alias; I changed it to search for the actual alias instead.

Consider the following code snippet: ``` #include bool test() { bool x = false; if (x) return x; return x; } ``` Emitting the CIR to `tmp.cir` using `-fclangir-mem2reg` produces the following CIR (truncated): ``` !s32i = !cir.int #fn_attr = #cir, nothrow = #cir.nothrow, optnone = #cir.optnone})> module { cir.func no_proto @test() -> !cir.bool extra(#fn_attr) { %0 = cir.const #cir.int<0> : !s32i %1 = cir.cast(int_to_bool, %0 : !s32i), !cir.bool cir.br ^bb1 ^bb1: // pred: ^bb0 cir.brcond %1 ^bb2, ^bb3 ^bb2: // pred: ^bb1 cir.return %1 : !cir.bool ^bb3: // pred: ^bb1 cir.br ^bb4 ^bb4: // pred: ^bb3 cir.return %1 : !cir.bool } } ``` Lowering the CIR to LLVM using `cir-opt tmp.cir -cir-to-llvm` fails with: ``` tmp.cir:5:10: error: failed to legalize operation 'llvm.zext' marked as erased ``` The CIR cast `%1 = cir.cast(int_to_bool, %0 : !s32i)` is lowered to a CIR comparison with zero, which is then lowered to an `LLVM::ICmpOp` and `LLVM::ZExtOp`. In the BrCond lowering, the zext is deleted when `zext->use_empty()`, but during this phase the lowering for the CIR above is not complete yet, because the zext will still have usage(s) later. The current check for when the zext is deleted is error-prone and can be improved. To fix this, in addition to checking that the use of the zext is empty, an additional check that the defining operation for the BrCond in the CIR (the cast operation in this case) is used exactly once is added. --- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 8 +++- clang/test/CIR/Lowering/brcond.cir | 43 +++++++++++++++++++ 2 files changed, 50 insertions(+), 1 deletion(-) create mode 100644 clang/test/CIR/Lowering/brcond.cir diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index ba9ac849c256..f96ddd1f7ba5 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -612,12 +612,18 @@ class CIRBrCondOpLowering mlir::ConversionPatternRewriter &rewriter) const override { mlir::Value i1Condition; + auto hasOneUse = false; + + if (auto defOp = brOp.getCond().getDefiningOp()) + hasOneUse = defOp->getResult(0).hasOneUse(); + if (auto defOp = adaptor.getCond().getDefiningOp()) { if (auto zext = dyn_cast(defOp)) { if (zext->use_empty() && zext->getOperand(0).getType() == rewriter.getI1Type()) { i1Condition = zext->getOperand(0); - rewriter.eraseOp(zext); + if (hasOneUse) + rewriter.eraseOp(zext); } } } diff --git a/clang/test/CIR/Lowering/brcond.cir b/clang/test/CIR/Lowering/brcond.cir new file mode 100644 index 000000000000..9586f70cf727 --- /dev/null +++ b/clang/test/CIR/Lowering/brcond.cir @@ -0,0 +1,43 @@ +// RUN: cir-opt %s -cir-to-llvm | FileCheck %s -check-prefix=MLIR +// RUN: cir-translate %s -cir-to-llvmir | FileCheck %s -check-prefix=LLVM + +!s32i = !cir.int +#fn_attr = #cir, nothrow = #cir.nothrow, optnone = #cir.optnone})> +module { cir.func no_proto @test() -> !cir.bool extra(#fn_attr) { + %0 = cir.const #cir.int<0> : !s32i + %1 = cir.cast(int_to_bool, %0 : !s32i), !cir.bool + cir.br ^bb1 + ^bb1: + cir.brcond %1 ^bb2, ^bb3 + ^bb2: + cir.return %1 : !cir.bool + ^bb3: + cir.br ^bb4 + ^bb4: + cir.return %1 : !cir.bool + } +} + +// MLIR: {{.*}} = llvm.mlir.constant(0 : i32) : i32 +// MLIR-NEXT: {{.*}} = llvm.mlir.constant(0 : i32) : i32 +// MLIR-NEXT: {{.*}} = llvm.icmp "ne" {{.*}}, {{.*}} : i32 +// MLIR-NEXT: {{.*}} = llvm.zext {{.*}} : i1 to i8 +// MLIR-NEXT: llvm.br ^bb1 +// MLIR-NEXT: ^bb1: +// MLIR-NEXT: llvm.cond_br {{.*}}, ^bb2, ^bb3 +// MLIR-NEXT: ^bb2: +// MLIR-NEXT: llvm.return {{.*}} : i8 +// MLIR-NEXT: ^bb3: +// MLIR-NEXT: llvm.br ^bb4 +// MLIR-NEXT: ^bb4: +// MLIR-NEXT: llvm.return {{.*}} : i8 + +// LLVM: br label {{.*}} +// LLVM: 1: +// LLVM: br i1 false, label {{.*}}, label {{.*}} +// LLVM: 2: +// LLVM: ret i8 0 +// LLVM: 3: +// LLVM: br label {{.*}} +// LLVM: 4: +// LLVM: ret i8 0 From 562dce9e3f4fc09ca2d0076ad9e8a3c256d9cb56 Mon Sep 17 00:00:00 2001 From: Bruno Cardoso Lopes Date: Tue, 10 Sep 2024 14:23:14 -0700 Subject: [PATCH 1814/2301] [CIR] Add some extra dumping to help with intermitent bug We haven't been able to find the root cause of https://github.com/llvm/clangir/issues/829 just yet, the problem does also not show up under a ASANified build.

Currently the "suitable" ternary operations are those ternary operations whose both branches satisfy either one of the following criteria: - The branch only contain a single `cir.yield` operation; - The branch contains a `cir.const` followed by a `cir.yield` that yields the constant value produced by the `cir.const`. - ~~The branch contains a `cir.load` followed by a `cir.yield` that yields the value loaded by the `cir.load`. The load operation cannot be volatile and must load from an alloca.~~ These criteria are hardcoded now so that simple C/C++ ternary expressions could be eventually lowered to a `cir.select` operation instead. --- .../CIR/Dialect/Transforms/CIRSimplify.cpp | 89 ++++++++++++++++++- clang/test/CIR/CodeGen/binop.cpp | 27 ++---- clang/test/CIR/CodeGen/ternary.cpp | 16 ++-- clang/test/CIR/Transforms/ternary-fold.cir | 60 +++++++++++++ clang/test/CIR/Transforms/ternary-fold.cpp | 56 ++++++++++++ 5 files changed, 214 insertions(+), 34 deletions(-) create mode 100644 clang/test/CIR/Transforms/ternary-fold.cir create mode 100644 clang/test/CIR/Transforms/ternary-fold.cpp diff --git a/clang/lib/CIR/Dialect/Transforms/CIRSimplify.cpp b/clang/lib/CIR/Dialect/Transforms/CIRSimplify.cpp index 7fd04f761f43..3aece6d74585 100644 --- a/clang/lib/CIR/Dialect/Transforms/CIRSimplify.cpp +++ b/clang/lib/CIR/Dialect/Transforms/CIRSimplify.cpp @@ -8,11 +8,15 @@ #include "PassDetail.h" #include "mlir/Dialect/Func/IR/FuncOps.h" +#include "mlir/IR/Block.h" +#include "mlir/IR/Operation.h" #include "mlir/IR/PatternMatch.h" +#include "mlir/IR/Region.h" #include "mlir/Support/LogicalResult.h" #include "mlir/Transforms/GreedyPatternRewriteDriver.h" #include "clang/CIR/Dialect/IR/CIRDialect.h" #include "clang/CIR/Dialect/Passes.h" +#include "llvm/ADT/SmallVector.h" using namespace mlir; using namespace cir; @@ -107,6 +111,85 @@ struct RemoveTrivialTry : public OpRewritePattern { } }; +/// Simplify suitable ternary operations into select operations. +/// +/// For now we only simplify those ternary operations whose true and false +/// branches directly yield a value or a constant.

This PR adds the calling convention attribute to CallOp directly, which is similar to LLVM, rather than adding the information to function type, which mimics Clang AST function type. The syntax of it in CIR assembly is between the function type and extra attributes, as follows: ```mlir %1 = cir.call %fnptr(%a) : (!fnptr, !s32i) -> !s32i cc(spir_kernel) extra(#fn_attr) ``` The verification of direct calls is not included. It will be included in the next patch extending CIRGen & Lowering. --- For every builder method of Call Op, an optional parameter `callingConv` is inserted right before the parameter of extra attribute. However, apart from the parser / printer, this PR does not introduce any functional changes. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 64 ++++++++++--------- clang/include/clang/CIR/Dialect/IR/CIROps.td | 19 +++++- .../clang/CIR/Interfaces/CIROpInterfaces.td | 3 + clang/lib/CIR/CodeGen/CIRGenCall.cpp | 6 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 27 +++++++- clang/test/CIR/IR/call-op-call-conv.cir | 27 ++++++++ 6 files changed, 110 insertions(+), 36 deletions(-) create mode 100644 clang/test/CIR/IR/call-op-call-conv.cir diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index a458547d330d..ed7d13588ec2 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -622,10 +622,11 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { mlir::SymbolRefAttr callee = mlir::SymbolRefAttr(), mlir::Type returnType = mlir::cir::VoidType(), mlir::ValueRange operands = mlir::ValueRange(), + mlir::cir::CallingConv callingConv = mlir::cir::CallingConv::C, mlir::cir::ExtraFuncAttributesAttr extraFnAttr = {}) { - mlir::cir::CallOp callOp = - create(loc, callee, returnType, operands);

This PR rename it and adjust the calls to it following OG CodeGen. To be specific, `setExtraAttributesForFunc` is called right after the initialization of `FuncOp`. But in OG CodeGen, the list of attributes is constructed by several more functions: `SetLLVMFunctionAttributes` and `SetLLVMFunctionAttributesForDefinition`. This results in diff in attributes of function declarations, which is reflected by the changes of test files. Apart from them, there is no functional change. In other words, the two code path calling `setCIRFunctionAttributesForDefinition` are tested by existing tests: * Caller `buildGlobalFunctionDefinition`: tested by `CIR/CodeGen/function-attrs.cpp`, ... * Caller `codegenCXXStructor`: tested by `CIR/CodeGen/delegating-ctor.cpp`, `defined-pure-virtual-func.cpp`, ... --- clang/lib/CIR/CodeGen/CIRGenCXX.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 34 ++++++++++--------- clang/lib/CIR/CodeGen/CIRGenModule.h | 10 +++--- clang/test/CIR/CodeGen/attributes.c | 2 +- clang/test/CIR/CodeGen/visibility-attribute.c | 6 ++-- 5 files changed, 29 insertions(+), 25 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenCXX.cpp b/clang/lib/CIR/CodeGen/CIRGenCXX.cpp index 85013189fd7e..d73222f5b79f 100644 --- a/clang/lib/CIR/CodeGen/CIRGenCXX.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenCXX.cpp @@ -287,7 +287,7 @@ mlir::cir::FuncOp CIRGenModule::codegenCXXStructor(GlobalDecl GD) { CurCGF = nullptr;

Here we have **4 kinds of operations**: (direct or indirect) x (`call` or `try_call`). According to our need and feasibility of constructing a test case, this PR includes: * For CIRGen, only direct `call`. Until now, the only extra calling conventions are SPIR ones, which cannot be set from source code manually using attributes. Meanwhile, OpenCL C *does not allow* function pointers or exceptions, therefore the only case remaining is direct call. * For Lowering, direct and indirect `call`, but not any `try_call`. Although it's possible to write all 4 kinds of calls with calling convention in ClangIR assembly, exceptions is quite hard to write and read. I prefer source-code-level test for it when it's available in the future. For example, possibly C++ `thiscall` with exceptions. * Extra: the verification of calling convention consistency for direct `call` and direct `try_call`. All unsupported cases are guarded by assertions or MLIR diags. --- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 19 +++++++----- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 6 ++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 29 ++++++++++++++----- .../CIR/CodeGen/OpenCL/spir-calling-conv.cl | 4 +++ clang/test/CIR/IR/invalid.cir | 15 ++++++++++ clang/test/CIR/Lowering/call-op-call-conv.cir | 22 ++++++++++++++ 6 files changed, 80 insertions(+), 15 deletions(-) create mode 100644 clang/test/CIR/Lowering/call-op-call-conv.cir diff --git a/clang/lib/CIR/CodeGen/CIRGenCall.cpp b/clang/lib/CIR/CodeGen/CIRGenCall.cpp index 656c80ce6f46..9acd226aafc6 100644 --- a/clang/lib/CIR/CodeGen/CIRGenCall.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenCall.cpp @@ -447,7 +447,7 @@ buildCallLikeOp(CIRGenFunction &CGF, mlir::Location callLoc, mlir::cir::FuncType indirectFuncTy, mlir::Value indirectFuncVal, mlir::cir::FuncOp directFuncOp, SmallVectorImpl &CIRCallArgs, - mlir::Operation *InvokeDest, + mlir::Operation *InvokeDest, mlir::cir::CallingConv callingConv, mlir::cir::ExtraFuncAttributesAttr extraFnAttrs) { auto &builder = CGF.getBuilder();

The PR involves both CIR generation and Lowering Prepare. In the rest of this description, we first introduce the concept of attribute annotate, then talk about expectations of LLVM regarding annotation, after it, we describe how ClangIR handles it in this PR. Finally, we list trivial differences between LLVM code generated by clang codegen and ClangIR codegen. **The concept of attribute annotate. and expected LLVM IR** the following is C code example of annotation. say in example.c `int *b __attribute__((annotate("withargs", "21", 12 ))); int *a __attribute__((annotate("oneargs", "21", ))); int *c __attribute__((annotate("noargs"))); ` here "withargs" is the annotation string, "21" and 12 are arguments for this annotation named "withargs". LLVM-based compiler is expected keep these information and build a global variable capturing all annotations used in the translation unit when emitting into LLVM IR. This global variable itself is **not** constant, but will be initialized with constants that are related to annotation representation, e.g. "withargs" should be literal string variable in IR. This global variable has a fixed name "llvm.global.annotations", and its of array of struct type, and should be initialized with a const array of const structs, each const struct is a representation of an annotation site, which has 5-field. [ptr to global var/func annotated, ptr to translation unit string const, line_no, annotation_name, ptr to arguments const] annotation name string and args constants, as well as this global var should be in section "llvm.metadata". e.g. In the above example, We shall have following in the generated LLVM IR like the following ``` @b = global ptr null, align 8 @.str = private unnamed_addr constant [9 x i8] c"withargs\00", section "llvm.metadata" @.str.1 = private unnamed_addr constant [10 x i8] c"example.c\00", section "llvm.metadata" @.str.2 = private unnamed_addr constant [3 x i8] c"21\00", align 1 @.args = private unnamed_addr constant { ptr, i32 } { ptr @.str.2, i32 12 }, section "llvm.metadata" @a = global ptr null, align 8 @.str.3 = private unnamed_addr constant [8 x i8] c"oneargs\00", section "llvm.metadata" @.args.4 = private unnamed_addr constant { ptr } { ptr @.str.2 }, section "llvm.metadata" @c = global ptr null, align 8 @.str.5 = private unnamed_addr constant [7 x i8] c"noargs\00", section "llvm.metadata" @llvm.global.annotations = appending global [3 x { ptr, ptr, ptr, i32, ptr }] [{ ptr, ptr, ptr, i32, ptr } { ptr @b, ptr @.str, ptr @.str.1, i32 1, ptr @.args }, { ptr, ptr, ptr, i32, ptr } { ptr @a, ptr @.str.3, ptr @.str.1, i32 2, ptr @.args.4 }, { ptr, ptr, ptr, i32, ptr } { ptr @c, ptr @.str.5, ptr @.str.1, i32 3, ptr null }], section "llvm.metadata" ``` notice that since variable c's annotation has no arg, the last field of its corresponding annotation entry is a nullptr. **ClangIR's handling of annotations** In CIR, we introduce AnnotationAttr to GlobalOp and FuncOp to record its annotations. That way, we are able to make fast query about annotation if in future a CIR pass is interested in them. We leave the work of generating const variables as well as global annotations' var to LLVM lowering. But at LoweringPrepare we collect all annotations and create a module attribute "cir.global_annotations" so to facilitate LLVM lowering. **Some implementation details and trivial differences between clangir generated LLVM code and vanilla LLVM code** 1. I suffix names of constants generated for annotation purpose with ".annotation" to avoid redefinition, but clang codegen doesn't do it. 3. clang codegen seems to visit FuncDecls in slightly different orders than CIR, thus, sometimes the order of elements of the initial value const array for llvm.global.annotations var is different from clang generated LLVMIR, it should be trivial, as I don't expect consumer of this var is assuming a fixed order of collecting annotations. Otherwise, clang codegen and clangir pretty much generate same LLVM IR for annotations! --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 71 +++++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 7 +- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 79 +++++- clang/lib/CIR/CodeGen/CIRGenModule.h | 34 +++ clang/lib/CIR/Dialect/IR/CIRAttrs.cpp | 40 +++ clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 15 +- .../Dialect/Transforms/LoweringPrepare.cpp | 37 +++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 245 +++++++++++++++++- .../CodeGen/attribute-annotate-multiple.cpp | 71 +++++ clang/test/CIR/IR/annotations.cir | 31 +++ clang/test/CIR/IR/invalid-annotations.cir | 32 +++ 11 files changed, 654 insertions(+), 8 deletions(-) create mode 100644 clang/test/CIR/CodeGen/attribute-annotate-multiple.cpp create mode 100644 clang/test/CIR/IR/annotations.cir create mode 100644 clang/test/CIR/IR/invalid-annotations.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 75180131adb3..59343514b645 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -1101,6 +1101,77 @@ def BitfieldInfoAttr : CIR_Attr<"BitfieldInfo", "bitfield_info"> { ];

This PR includes end-to-end implementation. The `convergent` attribute is set depending on languages, which is wrapped as `langOpts.assumeFunctionsAreConvergent()`. Therefore, in ClangIR, every `cir.func` under `#cir.lang` is set to be convergent. After lowering to LLVM IR, `PostOrderFunctionAttrs` pass will remove unnecessary `convergent` then. In other words, we will still see `convergent` on every function with `-O0`, but not with default optimization level. The test taken from `CodeGenOpenCL/convergent.cl` is a bit complicated. However, the core of it is that `convergent` is set properly for `convfun()` `non_convfun()` `f()` and `g()`. Merge of two `if` is more or less a result of generating the same LLVM IR as OG. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 4 + clang/lib/CIR/CodeGen/CIRGenCall.cpp | 40 +++++++ clang/lib/CIR/CodeGen/CIRGenModule.h | 13 +++ .../Lowering/DirectToLLVM/LowerToLLVMIR.cpp | 2 + clang/test/CIR/CodeGen/OpenCL/convergent.cl | 107 ++++++++++++++++++ 5 files changed, 166 insertions(+) create mode 100644 clang/test/CIR/CodeGen/OpenCL/convergent.cl diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 59343514b645..292d24315518 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -1042,6 +1042,10 @@ def NoThrowAttr : CIRUnitAttr<"NoThrow", "nothrow"> { let storageType = [{ NoThrowAttr }]; } +def ConvergentAttr : CIRUnitAttr<"Convergent", "convergent"> { + let storageType = [{ ConvergentAttr }]; +} + class CIR_GlobalCtorDtor : CIR_Attr<"Global" # name, "global_" # attrMnemonic> { diff --git a/clang/lib/CIR/CodeGen/CIRGenCall.cpp b/clang/lib/CIR/CodeGen/CIRGenCall.cpp index 3a36c3338a65..2e521fdbde46 100644 --- a/clang/lib/CIR/CodeGen/CIRGenCall.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenCall.cpp @@ -440,6 +440,9 @@ void CIRGenModule::constructAttributeList(StringRef Name, if (TargetDecl->hasAttr()) ; } + + getDefaultFunctionAttributes(Name, HasOptnone, AttrOnCallSite, funcAttrs); + } static mlir::cir::CIRCallOpInterface @@ -1559,3 +1562,40 @@ mlir::Value CIRGenFunction::buildVAArg(VAArgExpr *VE, Address &VAListAddr) { auto vaList = buildVAListRef(VE->getSubExpr()).getPointer(); return builder.create(loc, type, vaList); } + +static void getTrivialDefaultFunctionAttributes( + StringRef name, bool hasOptnone, const CodeGenOptions &codeGenOpts, + const LangOptions &langOpts, bool attrOnCallSite, CIRGenModule &CGM, + mlir::NamedAttrList &funcAttrs) { + + if (langOpts.assumeFunctionsAreConvergent()) { + // Conservatively, mark all functions and calls in CUDA and OpenCL as + // convergent (meaning, they may call an intrinsically convergent op, such + // as __syncthreads() / barrier(), and so can't have certain optimizations + // applied around them).

For instance, the next code : ``` void foo(int a, float b) { struct A { int x; }; struct A loc = {a}; { struct A { float y; }; struct A loc = {b}; } } ``` fails with on the next assertion: `Unable to find record layout information for type`. The problem is that we don't create record layout for the structures with equal names and `CIRGenTypes::convertRecordDeclType` returns the wrong type for the second struct type in the example above. This PR fixes this problem. In the original codegen the call to `Ty->setName(name)` resolves name collisions and assign a proper name for the type. In our case looks like we need to use the same approach as we did for the anonymous structures, i.e. to track the used names in the builder. Also, I fixed the struct type creation. Previously, the type was created several times - first in the `CIRGenTypes::convertRecordDeclType` and then in the `CIRGenTypes::computeRecordLayout`. This is why the indexes used by the anonymous structures naming had relatively big values and this is where the most changes on the tests come from. --- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 20 ++++++-- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 2 +- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 4 +- clang/test/CIR/CodeGen/bitfields.c | 4 +- clang/test/CIR/CodeGen/bitfields.cpp | 4 +- clang/test/CIR/CodeGen/compound-literal.c | 4 +- clang/test/CIR/CodeGen/coro-task.cpp | 4 +- clang/test/CIR/CodeGen/forward-decls.cpp | 13 +++--- clang/test/CIR/CodeGen/globals.c | 8 ++-- clang/test/CIR/CodeGen/lambda.cpp | 46 +++++++++---------- clang/test/CIR/CodeGen/string-literals.c | 2 +- clang/test/CIR/CodeGen/struct.c | 14 ++++++ clang/test/CIR/CodeGen/union-init.c | 6 +-- clang/test/CIR/CodeGen/union.cpp | 12 ++--- 14 files changed, 83 insertions(+), 60 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.h b/clang/lib/CIR/CodeGen/CIRGenBuilder.h index 5342612fdb7d..1ba6e9447a09 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuilder.h +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.h @@ -53,16 +53,26 @@ class CIRGenBuilderTy : public CIRBaseBuilderTy { llvm::RoundingMode DefaultConstrainedRounding = llvm::RoundingMode::Dynamic; llvm::StringMap GlobalsVersioning; - llvm::StringSet<> anonRecordNames; + llvm::StringMap RecordNames; public: CIRGenBuilderTy(mlir::MLIRContext &C, const CIRGenTypeCache &tc) - : CIRBaseBuilderTy(C), typeCache(tc) {} + : CIRBaseBuilderTy(C), typeCache(tc) { + RecordNames["anon"] = 0; // in order to start from the name "anon.0" + } std::string getUniqueAnonRecordName() { - std::string name = "anon." + std::to_string(anonRecordNames.size()); - anonRecordNames.insert(name); - return name; + return getUniqueRecordName("anon"); + } + + std::string getUniqueRecordName(const std::string& baseName) { + auto it = RecordNames.find(baseName); + if (it == RecordNames.end()) { + RecordNames[baseName] = 0; + return baseName; + } + + return baseName + "." + std::to_string(RecordNames[baseName]++); } // diff --git a/clang/lib/CIR/CodeGen/CIRGenTypes.cpp b/clang/lib/CIR/CodeGen/CIRGenTypes.cpp index ab2e4129ac60..0cae7cdbf352 100644 --- a/clang/lib/CIR/CodeGen/CIRGenTypes.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenTypes.cpp @@ -92,7 +92,7 @@ std::string CIRGenTypes::getRecordTypeName(const clang::RecordDecl *recordDecl, if (!suffix.empty()) outStream << suffix; - return std::string(typeName); + return Builder.getUniqueRecordName(std::string(typeName)); } /// Return true if the specified type is already completely laid out. diff --git a/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp b/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp index 1e58ee4ff198..9ad81831f224 100644 --- a/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp +++ b/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp @@ -689,8 +689,8 @@ CIRGenTypes::computeRecordLayout(const RecordDecl *D, // Fill in the struct *after* computing the base type.

int c; } D; typedef struct { D e; int f; } E; void f1() { E a = {}; } ``` When emitting the CIR using `bin/clang test.c -Xclang -fclangir -Xclang -emit-cir -S -o -` the current implementation gets: ``` NYI UNREACHABLE executed at ~/clangir/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp:338! ``` This is only one of the many tests where this happens. Comparing the implementations of `CIR/CodeGen/CIRRecordLayoutBuilder.cpp` and clang's codegen `lib/CodeGen/CGRecordLayoutBuilder.cpp`, there is some padding missing for packed structures, and some alignments that need to be corrected. This PR also updates 2 existing tests. In the first test, `structural-binding.cpp`, I updated some `cir.get_member` indexes. In the second test, `packed-structs.c`, I updated the `cir` layout for the structure, and added more tests. I have compared the changes I made in the tests to the original clang codegen and everything seems fine. --- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 35 +++++- clang/lib/CIR/Dialect/IR/CIRDataLayout.cpp | 7 +- clang/test/CIR/CodeGen/packed-structs.c | 110 ++++++++++++++++-- clang/test/CIR/CodeGen/structural-binding.cpp | 10 +- 4 files changed, 145 insertions(+), 17 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp b/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp index 9ad81831f224..b6e48d534790 100644 --- a/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp +++ b/clang/lib/CIR/CodeGen/CIRRecordLayoutBuilder.cpp @@ -69,6 +69,8 @@ struct CIRRecordLowering final { /// Determines if we need a packed llvm struct. void determinePacked(bool NVBaseType); + /// Inserts padding everywhere it's needed. + void insertPadding(); void computeVolatileBitfields(); void accumulateBases(); @@ -294,6 +296,7 @@ void CIRRecordLowering::lower(bool nonVirtualBaseType) { members.push_back(StorageInfo(Size, getUIntNType(8))); determinePacked(nonVirtualBaseType); + insertPadding(); members.pop_back(); fillOutputFields(); @@ -657,6 +660,33 @@ void CIRRecordLowering::determinePacked(bool NVBaseType) { members.back().data = getUIntNType(astContext.toBits(Alignment)); } +void CIRRecordLowering::insertPadding() { + std::vector> Padding; + CharUnits Size = CharUnits::Zero(); + for (std::vector::const_iterator Member = members.begin(), + MemberEnd = members.end(); + Member != MemberEnd; ++Member) { + if (!Member->data) + continue; + CharUnits Offset = Member->offset; + assert(Offset >= Size); + // Insert padding if we need to. + if (Offset != + Size.alignTo(isPacked ?

I tried to address the problem in the newest commit. The changes of the PR since the last landed one includes: - Move the definition of `cir::CIRGenConsumer` to `clang/include/clang/CIRFrontendAction/CIRGenConsumer.h`, and leave its `HandleTranslationUnit` interface is left empty. So that `cir::CIRGenConsumer` won't need to depend on CodeGen any more. - Change the old definition of `cir::CIRGenConsumer` in `clang/lib/CIR/FrontendAction/CIRGenAction.cpp` and to `CIRLoweringConsumer`, inherited from `cir::CIRGenConsumer`, which implements the original `HandleTranslationUnit` interface.

Consider the following code snippet `test.c`: ``` void foo() { char arr[4][1] = {"a", "b", "c", "d"}; } ``` When ran with `bin/clang test.c -Xclang -fclangir -Xclang -emit-llvm -S -o -`, It produces the following error: ``` ~/clangir/llvm/include/llvm/Support/Casting.h:566: decltype(auto) llvm::cast(const From&) [with To = mlir::ArrayAttr; From = mlir::Attribute]: Assertion `isa(Val) && "cast() argument of incompatible type!"' failed. ``` The bug can be traced back to `LoweringHelpers.cpp`. It considers the values in the array as integer types, and this causes an error in this case. This PR updates `convertToDenseElementsAttrImpl` when the array contains string attributes. I have also added one more similar test. Note that in the tests I used a **literal match** to avoid matching as regex, so `!dbg` is useful. --- clang/lib/CIR/Lowering/LoweringHelpers.cpp | 38 ++++++++++++++++------ clang/test/CIR/Lowering/array-init.c | 17 ++++++++++ 2 files changed, 45 insertions(+), 10 deletions(-) diff --git a/clang/lib/CIR/Lowering/LoweringHelpers.cpp b/clang/lib/CIR/Lowering/LoweringHelpers.cpp index debe7881d0c4..06c92ae12472 100644 --- a/clang/lib/CIR/Lowering/LoweringHelpers.cpp +++ b/clang/lib/CIR/Lowering/LoweringHelpers.cpp @@ -61,9 +61,34 @@ mlir::Type getNestedTypeAndElemQuantity(mlir::Type Ty, unsigned &elemQuantity) { return nestTy;

The `cir-canonicalize` pass runs transformations that do not affect CIR-to-source fidelity much, such as operation folding and redundant operation elimination. On the other hand, the new `cir-simplify` pass runs transformations that may significantly change the code and break high-level code analysis passes, such as more aggresive code optimizations. This PR also updates the CIR-to-CIR pipeline to fit these two new passes. The `cir-canonicalize` pass is moved to the very front of the pipeline, while the new `cir-simplify` pass is moved to the back of the pipeline (but still before lowering prepare of course). Additionally, the new `cir-simplify` now only runs when the user specifies a non-zero optimization level on the frontend. Also fixed some typos and resolved some `clang-tidy` complaints along the way. Resolves #827 . --- clang/include/clang/CIR/CIRToCIRPasses.h | 4 +- clang/include/clang/CIR/Dialect/Passes.h | 1 + clang/include/clang/CIR/Dialect/Passes.td | 35 ++-- clang/lib/CIR/CodeGen/CIRPasses.cpp | 9 +- .../Dialect/Transforms/CIRCanonicalize.cpp | 187 ++++++++++++++++++ .../CIR/Dialect/Transforms/CIRSimplify.cpp | 136 +------------ .../lib/CIR/Dialect/Transforms/CMakeLists.txt | 1 + clang/lib/CIR/FrontendAction/CIRGenAction.cpp | 1 + clang/test/CIR/CodeGen/binop.cpp | 2 +- clang/test/CIR/CodeGen/complex.c | 8 +- clang/test/CIR/CodeGen/ternary.cpp | 2 +- clang/test/CIR/Transforms/builtin-assume.cir | 4 +- clang/test/CIR/Transforms/merge-cleanups.cir | 2 +- clang/test/CIR/Transforms/select.cir | 2 +- clang/test/CIR/Transforms/simpl.c | 4 +- clang/test/CIR/Transforms/simpl.cir | 2 +- clang/test/CIR/Transforms/ternary-fold.cir | 2 +- clang/test/CIR/Transforms/ternary-fold.cpp | 10 +- clang/test/CIR/mlirprint.c | 8 +- clang/tools/cir-opt/cir-opt.cpp | 3 + 20 files changed, 250 insertions(+), 173 deletions(-) create mode 100644 clang/lib/CIR/Dialect/Transforms/CIRCanonicalize.cpp diff --git a/clang/include/clang/CIR/CIRToCIRPasses.h b/clang/include/clang/CIR/CIRToCIRPasses.h index a88fba7a76e3..4ad4aeebb22e 100644 --- a/clang/include/clang/CIR/CIRToCIRPasses.h +++ b/clang/include/clang/CIR/CIRToCIRPasses.h @@ -34,8 +34,8 @@ mlir::LogicalResult runCIRToCIRPasses( llvm::StringRef lifetimeOpts, bool enableIdiomRecognizer, llvm::StringRef idiomRecognizerOpts, bool enableLibOpt, llvm::StringRef libOptOpts, std::string &passOptParsingFailure, - bool flattenCIR, bool emitMLIR, bool enableCallConvLowering, - bool enableMem2reg); + bool enableCIRSimplify, bool flattenCIR, bool emitMLIR, + bool enableCallConvLowering, bool enableMem2reg); } // namespace cir diff --git a/clang/include/clang/CIR/Dialect/Passes.h b/clang/include/clang/CIR/Dialect/Passes.h index 116966d52f15..67e9da2246b6 100644 --- a/clang/include/clang/CIR/Dialect/Passes.h +++ b/clang/include/clang/CIR/Dialect/Passes.h @@ -26,6 +26,7 @@ std::unique_ptr createLifetimeCheckPass(ArrayRef remark, ArrayRef hist, unsigned hist_limit, clang::ASTContext *astCtx); +std::unique_ptr createCIRCanonicalizePass(); std::unique_ptr createCIRSimplifyPass(); std::unique_ptr createDropASTPass(); std::unique_ptr createSCFPreparePass(); diff --git a/clang/include/clang/CIR/Dialect/Passes.td b/clang/include/clang/CIR/Dialect/Passes.td index 1c17ca9c5ed1..d72bf0bfd420 100644 --- a/clang/include/clang/CIR/Dialect/Passes.td +++ b/clang/include/clang/CIR/Dialect/Passes.td @@ -11,22 +11,33 @@ include "mlir/Pass/PassBase.td" -def CIRSimplify : Pass<"cir-simplify"> { - let summary = "Performs CIR simplification"; +def CIRCanonicalize : Pass<"cir-canonicalize"> { + let summary = "Performs CIR canonicalization"; let description = [{ - The pass rewrites CIR and removes some redundant operations. + Perform canonicalizations on CIR and removes some redundant operations. + + This pass performs basic cleanup and canonicalization transformations that + hopefully do not affect CIR-to-source fidelity and high-level code analysis + passes too much.

Consider the following code snippet `test.c`: ``` typedef struct { int a; int b[2]; } A; int bar() { return 42; } void foo() { A a = {bar(), {}}; } ``` When ran with `bin/clang test.c -Xclang -fclangir -Xclang -emit-cir -S -o -`, It produces the following error: ``` ~/clangir/clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp:483: void {anonymous}::AggExprEmitter::buildArrayInit(cir::Address, mlir::cir::ArrayType, clang::QualType, clang::Expr*, llvm::ArrayRef, clang::Expr*): Assertion `NumInitElements != 0' failed. ``` The error can be traced back to `CIRGenExprAgg.cpp`, and the fix is simple.

} else if (lastCaseBlock) { // This means it's a random stmt following up a case, just // emit it as part of previous known case. mlir::OpBuilder::InsertionGuard guardCase(builder); builder.setInsertionPointToEnd(lastCaseBlock); res = buildStmt(c, /*useCurrentScope=*/!isa(c)); } else { llvm_unreachable("statement doesn't belong to any case region, NYI"); } lastCaseBlock = builder.getBlock(); if (res.failed()) break; } ``` However, maybe this is an oversight, in the branch of ` if (lastCaseBlock)`, the insertion point will be updated automatically when the RAII object `guardCase` destroys, then we can assign the correct value for `lastCaseBlock` later. So we will see the weird code pattern in the issue side. BTW, I found the codes in CIRGenStmt.cpp are far more less similar with the ones other code gen places. Is this intentional?

The cause is clear. We call `buildStmt` when we build the label stmt. To solve this, I think we should be able to build case stmt in buildStmt. But the new problem is, we need to pass the information like caseAttr and condType.

This PR has simliar test case organization as to [PR882](https://github.com/llvm/clangir/pull/882) Notice that comparing to OG, this PR combines cases for some pairs of intrinsics such as BI__builtin_neon_vget_lane_f32 and BI__builtin_neon_vdups_lane_f32. They have the same code generated in OG and CIRGen OG separate them into different case handling because it passes mnemonics which are different. CIRGen doesn't pass that so why not combine them.

Also add function buildCommonNeonBuiltinExpr just like OG's emitCommonNeonBuiltinExpr. This might help consolidate neon cases and share common code. Notice: - I pretty much keep the skeleton of OG's emitCommonNeonBuiltinExpr at the cost of that we didn't use a few variables they calculate. They might help in the future. - The purpose of having CommonNeonBuiltinExpr is to reduce implementation code duplication. So far, we only have one type implemented, and it's hard for CIR to be more generic. But we should see if in future we can have different types of intrinsics share more generic code path. --------- Co-authored-by: Guojin He --- clang/include/clang/CIR/MissingFeatures.h | 3 + clang/lib/CIR/CodeGen/ABIInfo.h | 2 + .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 59 +++++- clang/lib/CIR/CodeGen/CIRGenFunction.h | 5 + clang/lib/CIR/CodeGen/TargetInfo.cpp | 6 + clang/test/CIR/CodeGen/aarch64-neon-vqadd.c | 179 ++++++++++++++++++ 6 files changed, 250 insertions(+), 4 deletions(-) create mode 100644 clang/test/CIR/CodeGen/aarch64-neon-vqadd.c diff --git a/clang/include/clang/CIR/MissingFeatures.h b/clang/include/clang/CIR/MissingFeatures.h index 2577af98e5e5..3540300d622c 100644 --- a/clang/include/clang/CIR/MissingFeatures.h +++ b/clang/include/clang/CIR/MissingFeatures.h @@ -136,6 +136,9 @@ struct MissingFeatures { // AArch64 Neon builtin related. static bool buildNeonShiftVector() { return false; } + // ABIInfo queries. + static bool useTargetLoweringABIInfo() { return false; } + // Misc static bool cacheRecordLayouts() { return false; } static bool capturedByInit() { return false; } diff --git a/clang/lib/CIR/CodeGen/ABIInfo.h b/clang/lib/CIR/CodeGen/ABIInfo.h index 5a2e3ff56ca4..a4cd7a5a666c 100644 --- a/clang/lib/CIR/CodeGen/ABIInfo.h +++ b/clang/lib/CIR/CodeGen/ABIInfo.h @@ -35,6 +35,8 @@ class ABIInfo { virtual void computeInfo(CIRGenFunctionInfo &FI) const = 0; + virtual bool allowBFloatArgsAndRet() const { return false; } + // Implement the Type::IsPromotableIntegerType for ABI specific needs.

This update changes the default behavior to always apply the CC lowering pass, with an option to disable it using the `-fno-clangir-call-conv-lowering` flag if necessary. The primary objective is to make this pass a mandatory step in the compilation pipeline. This ensures that future contributions correctly implement the CC lowering for both existing and new targets, resulting in more consistent and accurate code generation. From an implementation perspective, several `llvm_unreachable` statements have been substituted with a new `assert_or_abort` macro. This macro can be configured to either trigger a non-blocking assertion or a blocking unreachable statement. This facilitates a test-by-testa incremental development as it does not required you to know which code path a test will trigger an just cause a crash if it does. A few notable changes: - Support multi-block function in CC lowering - Ignore pointer-related CC lowering - Ignore no-proto functions CC lowering - Handle missing type evaluation kinds - Fix CC lowering for function declarations - Unblock indirect function calls - Disable CC lowering pass on several tests --- clang/include/clang/CIR/Dialect/Passes.h | 2 +- clang/include/clang/CIR/MissingFeatures.h | 41 ++++++++ clang/include/clang/Driver/Options.td | 11 ++- .../include/clang/Frontend/FrontendOptions.h | 2 +- clang/lib/CIR/CodeGen/CIRPasses.cpp | 11 +-- .../Dialect/Transforms/CallConvLowering.cpp | 8 +- .../Transforms/TargetLowering/ABIInfo.cpp | 2 +- .../Transforms/TargetLowering/ABIInfoImpl.cpp | 7 +- .../TargetLowering/CIRLowerContext.cpp | 17 ++-- .../TargetLowering/CIRRecordLayout.cpp | 6 +- .../TargetLowering/CIRToCIRArgMapping.h | 10 +- .../TargetLowering/ItaniumCXXABI.cpp | 6 +- .../Transforms/TargetLowering/LowerCall.cpp | 36 +++---- .../TargetLowering/LowerFunction.cpp | 95 +++++++++++-------- .../TargetLowering/LowerFunctionInfo.h | 9 +- .../Transforms/TargetLowering/LowerModule.cpp | 13 ++- .../Transforms/TargetLowering/LowerModule.h | 2 +- .../Transforms/TargetLowering/LowerTypes.cpp | 14 +-- .../TargetLowering/RecordLayoutBuilder.cpp | 57 +++++------ .../TargetLowering/Targets/AArch64.cpp | 8 +- .../Targets/LoweringPrepareAArch64CXXABI.cpp | 52 +++++----- .../Targets/LoweringPrepareItaniumCXXABI.cpp | 12 +-- .../TargetLowering/Targets/SPIR.cpp | 2 +- .../Transforms/TargetLowering/Targets/X86.cpp | 36 ++++--- clang/lib/CIR/FrontendAction/CIRGenAction.cpp | 6 +- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 2 +- clang/lib/Frontend/CompilerInvocation.cpp | 2 +- clang/test/CIR/CodeGen/global-new.cpp | 2 +- clang/test/CIR/CodeGen/try-catch-dtors.cpp | 2 +- clang/test/CIR/Lowering/try-catch.cpp | 2 +- .../aarch64-call-conv-lowering-pass.cpp | 2 +- .../x86_64/x86_64-call-conv-lowering-pass.cpp | 2 +- 32 files changed, 282 insertions(+), 197 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/Passes.h b/clang/include/clang/CIR/Dialect/Passes.h index 67e9da2246b6..c9b936ca98fb 100644 --- a/clang/include/clang/CIR/Dialect/Passes.h +++ b/clang/include/clang/CIR/Dialect/Passes.h @@ -42,7 +42,7 @@ std::unique_ptr createGotoSolverPass(); /// Create a pass to lower ABI-independent function definitions/calls. std::unique_ptr createCallConvLoweringPass(); -void populateCIRPreLoweringPasses(mlir::OpPassManager &pm); +void populateCIRPreLoweringPasses(mlir::OpPassManager &pm, bool useCCLowering); //===----------------------------------------------------------------------===// // Registration diff --git a/clang/include/clang/CIR/MissingFeatures.h b/clang/include/clang/CIR/MissingFeatures.h index 3540300d622c..e60ae97b8570 100644 --- a/clang/include/clang/CIR/MissingFeatures.h +++ b/clang/include/clang/CIR/MissingFeatures.h @@ -15,6 +15,27 @@ #ifndef CLANG_CIR_MISSINGFEATURES_H #define CLANG_CIR_MISSINGFEATURES_H +constexpr bool cirMissingFeatureAssertionMode = + true; // Change to `false` to use llvm_unreachable + +#define NOTE \ + " Target lowering is now required.

Actually the missing stage is CIRGen. There are two places where `GV.setConstant` is called: * `buildGlobalVarDefinition` * `getOrCreateCIRGlobal` Therefore, the primary test `global-constant.c` contains a global definition and a global declaration with use, which should be enough to cover the two paths. A test for OpenCL `constant` qualified global is also added.

double b[N]; } s; double *b = s.b; void foo() { double x = 0; for (int i = 0; i < N; i++) x += b[i]; } int main() { foo(); return 0; } ``` Running `bin/clang tmp.c -fclangir -o tmp && ./tmp` causes a segmentation fault. I compared the LLVM IR with and without CIR and noticed a difference which causes this: `@b = global ptr getelementptr inbounds (%struct.S, ptr @s, i32 0, i32 1)` // no CIR `@b = global ptr getelementptr inbounds (%struct.S, ptr @s, i32 1)` // with CIR It seems there is a missing index when creating global pointers from structs.

Also changed [neon-ldst.c](https://github.com/llvm/clangir/compare/main...ghehg:clangir-llvm-ghehg:macM3?expand=1#diff-ea4814b6503bff2b7bc4afc6400565e6e89e5785bfcda587dc8401d8de5d3a22) to make it have the same RUN options as OG [clang/test/CodeGen/aarch64-neon-intrinsics.c](https://github.com/llvm/clangir/blob/main/clang/test/CodeGen/aarch64-neon-intrinsics.c) Those options help us to avoid checking load/store pairs thus make the test less verbose and easier to compare against OG.

6f175a10d3683f0a0bb7adb8478286466e055202 Mon Sep 17 00:00:00 2001 From: David Olsen Date: Fri, 4 Oct 2024 17:50:59 -0700 Subject: [PATCH 1913/2301] [CIR] Derived-to-base conversions (#937) Implement derived-to-base address conversions for non-virtual base classes. The code gen for this situation was only implemented when the offset was zero, and it simply created a `cir.base_class_addr` op for which no lowering or other transformation existed. Conversion to a virtual base class is not yet implemented. Two new fields are added to the `cir.base_class_addr` operation: the byte offset of the necessary adjustment, and a boolean flag indicating whether the source operand may be null. The offset is easy to compute in the front end while the entire path of intermediate classes is still available. It would be difficult for the back end to recompute the offset. So it is best to store it in the operation. The null-pointer check is best done late in the lowering process. But whether or not the null-pointer check is needed is only known by the front end; the back end can't figure that out. So that flag needs to be stored in the operation. `CIRGenFunction::getAddressOfBaseClass` was largely rewritten. The code path no longer matches the equivalent function in the LLVM IR code gen, because the generated ClangIR is quite different from the generated LLVM IR. `cir.base_class_addr` is lowered to LLVM IR as a `getelementptr` operation. If a null-pointer check is needed, then that is wrapped in a `select` operation. When generating code for a constructor or destructor, an incorrect `cir.ptr_stride` op was used to convert the pointer to a base class. The code was assuming that the operand of `cir.ptr_stride` was measured in bytes; the operand is the number elements, not the number of bytes. So the base class constructor was being called on the wrong chunk of memory. Fix this by using a `cir.base_class_addr` op instead of `cir.ptr_stride` in this scenario. The use of `cir.ptr_stride` in `ApplyNonVirtualAndVirtualOffset` had the same problem. Continue using `cir.ptr_stride` here, but temporarily convert the pointer to type `char*` so the pointer is adjusted correctly. Adjust the expected results of three existing tests in response to these changes. Add two new tests, one code gen and one lowering, to cover the case where a base class is at a non-zero offset. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 22 ++++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 8 +- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 83 +++++++++---------- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 36 +++++++- clang/test/CIR/CodeGen/derived-to-base.cpp | 33 +++++++- clang/test/CIR/CodeGen/multi-vtable.cpp | 8 +- clang/test/CIR/CodeGen/vtable-rtti.cpp | 2 +- clang/test/CIR/Lowering/derived-to-base.cpp | 28 +++++++ 8 files changed, 159 insertions(+), 61 deletions(-) create mode 100644 clang/test/CIR/Lowering/derived-to-base.cpp diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 1057e0308aee..4b3a5ec6862e 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2960,23 +2960,37 @@ def BaseClassAddrOp : CIR_Op<"base_class_addr"> { let summary = "Get the base class address for a class/struct"; let description = [{ The `cir.base_class_addr` operaration gets the address of a particular - base class given a derived class pointer. + non-virtual base class given a derived class pointer.

The op builders take care of this automatically if you pass the function type, so change our lowering logic to do so. Add tests for this as well as a missing test for indirect function call lowering.

783f05431da45d4a5a19b5c5ba6d780735a0064c Mon Sep 17 00:00:00 2001 From: Vinicius Couto Espindola <34522047+sitio-couto@users.noreply.github.com> Date: Thu, 10 Oct 2024 21:41:49 -0300 Subject: [PATCH 1930/2301] Reapply and patch "[CIR][ABI] Apply CC lowering pass by default (#842)" (#944) This reverts commit 8f699fd and fixes some issues, namely: - CC lowering pass will no longer fail if the function has no AST information that won't be used. - Fixed CC lowering not disabling when running certain `cc1` compilation commands. - CC lowering can now be disabled when calling `cir-opt` and `cir-translate`. - Compilation commands that generate Object files should now invoke CC lowering by default. --- clang/include/clang/CIR/Dialect/Passes.h | 2 +- clang/include/clang/CIR/LowerToLLVM.h |

This PR fix it by the usual copy-pasta from the original codegen :) So let's take a look at the code: ``` void foo(x) short x; {} int main() { foo(4); return 0; } ``` and CIR for `foo` function is: ``` cir.func @foo(%arg0: !s32i) { %0 = cir.alloca !s16i, !cir.ptr, ["x", init] %1 = cir.cast(bitcast, %0 : !cir.ptr), !cir.ptr cir.store %arg0, %1 : !s32i, !cir.ptr cir.return } ``` We bitcast the **address** (!!!) and store a value of a bigger size there. And now everything looks fine: ``` cir.func no_proto @foo(%arg0: !s32i) { %0 = cir.alloca !s16i, !cir.ptr, ["x", init] %1 = cir.cast(integral, %arg0 : !s32i), !s16i cir.store %1, %0 : !s16i, !cir.ptr cir.return } ``` We truncate an argument and store it. P.S. The `bitcast` that was there before looks a little bit suspicious and dangerous. Are we sure we can do this unconditional cast while we create `StoreOp` ? --- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 32 +++++++++++++++++++++++- clang/test/CIR/CodeGen/kr-func-promote.c | 13 ++++++++++ 2 files changed, 44 insertions(+), 1 deletion(-) create mode 100644 clang/test/CIR/CodeGen/kr-func-promote.c diff --git a/clang/lib/CIR/CodeGen/CIRGenFunction.cpp b/clang/lib/CIR/CodeGen/CIRGenFunction.cpp index d60b2d177919..d7a7ac0a1f0f 100644 --- a/clang/lib/CIR/CodeGen/CIRGenFunction.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenFunction.cpp @@ -970,6 +970,29 @@ static bool matchesStlAllocatorFn(const Decl *D, const ASTContext &Ctx) { return true; } +/// TODO: this should live in `buildFunctionProlog` +/// An argument came in as a promoted argument; demote it back to its +/// declared type. +static mlir::Value emitArgumentDemotion(CIRGenFunction &CGF, const VarDecl *var, + mlir::Value value) { + mlir::Type ty = CGF.ConvertType(var->getType()); + + // This can happen with promotions that actually don't change the + // underlying type, like the enum promotions. + if (value.getType() == ty) + return value; + + assert( + (isa(ty) || mlir::cir::isAnyFloatingPointType(ty)) && + "unexpected promotion type"); + + if (isa(ty)) + return CGF.getBuilder().CIRBaseBuilderTy::createIntCast(value, ty); + + return CGF.getBuilder().CIRBaseBuilderTy::createCast( + mlir::cir::CastKind::floating, value, ty); +} + void CIRGenFunction::StartFunction(GlobalDecl GD, QualType RetTy, mlir::cir::FuncOp Fn, const CIRGenFunctionInfo &FnInfo, @@ -1239,7 +1262,7 @@ void CIRGenFunction::StartFunction(GlobalDecl GD, QualType RetTy, // Declare all the function arguments in the symbol table. for (const auto nameValue : llvm::zip(Args, EntryBB->getArguments())) { auto *paramVar = std::get<0>(nameValue); - auto paramVal = std::get<1>(nameValue); + mlir::Value paramVal = std::get<1>(nameValue); auto alignment = getContext().getDeclAlign(paramVar); auto paramLoc = getLoc(paramVar->getSourceRange()); paramVal.setLoc(paramLoc); @@ -1252,6 +1275,13 @@ void CIRGenFunction::StartFunction(GlobalDecl GD, QualType RetTy, auto address = Address(addr, alignment); setAddrOfLocalVar(paramVar, address); + // TODO: this should live in `buildFunctionProlog` + bool isPromoted = isa(paramVar) && + cast(paramVar)->isKNRPromoted(); + assert(!MissingFeatures::constructABIArgDirectExtend()); + if (isPromoted) + paramVal = emitArgumentDemotion(*this, paramVar, paramVal); + // Location of the store to the param storage tracked as beginning of // the function body. auto fnBodyBegin = getLoc(FD->getBody()->getBeginLoc()); diff --git a/clang/test/CIR/CodeGen/kr-func-promote.c b/clang/test/CIR/CodeGen/kr-func-promote.c new file mode 100644 index 000000000000..1edfcd805c6f --- /dev/null +++ b/clang/test/CIR/CodeGen/kr-func-promote.c @@ -0,0 +1,13 @@ +// RUN: %clang_cc1 -triple x86_64-unknown-linux-gnu -fclangir -emit-cir %s -o - | FileCheck %s + +// CHECK: cir.func {{.*}}@foo(%arg0: !s32i +// CHECK: %0 = cir.alloca !s16i, !cir.ptr, ["x", init] +// CHECK: %1 = cir.cast(integral, %arg0 : !s32i) +// CHECK: cir.store %1, %0 : !s16i, !cir.ptr +void foo(x) short x; {} + +// CHECK: cir.func no_proto @bar(%arg0: !cir.double +// CHECK: %0 = cir.alloca !cir.float, !cir.ptr, ["f", init] +// CHECK: %1 = cir.cast(floating, %arg0 : !cir.double), !cir.float +// CHECK: cir.store %1, %0 : !cir.float, !cir.ptr +void bar(f) float f; {} From bffff3d495214cea1c74c571ec3723c16d306827 Mon Sep 17 00:00:00 2001 From: Sirui Mu Date: Fri, 11 Oct 2024 08:45:12 +0800 Subject: [PATCH 1932/2301] [CIR][CIRGen] Add const attribute to alloca operations (#892) This PR tries to give a simple initial implementation for eliminating redundant loads of constant objects, an idea originally posted by OfekShilon.

Proof: We generate VecCreateOp [here ](https://github.com/llvm/clangir/blob/2ca12fe5ec3a1e7279256f069010be2d68200585/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp#L1975) And it's OG counterpart is [here](https://github.com/llvm/clangir/blob/2ca12fe5ec3a1e7279256f069010be2d68200585/clang/lib/CodeGen/CGExprScalar.cpp#L2096) OG uses PoisonValue. As to VecSplatOp, OG unconditionally [chooses PoisonValue ](https://github.com/llvm/clangir/blob/2ca12fe5ec3a1e7279256f069010be2d68200585/llvm/lib/IR/IRBuilder.cpp#L1204) A even more solid proof for this case is that when we use OG to generate code for our test case I changed in this PR , its always using poison instead of undef as far as VecSplat and VecCreate is concerned. The [OG generated code for vectype-ext.cpp ](https://godbolt.org/z/eqx1rns86) here. The [OG generated code for vectype.cpp ](https://godbolt.org/z/frMjbKGeT) here. For reference, generated CIR for the test case vectype-ext.cpp is [here](https://godbolt.org/z/frMjbKGeT) This is to unblock https://github.com/llvm/clangir/pull/936/ to help it set on the right path. Note: There might be other CIR vec ops that need to choose Poison to be consistent with OG, but I'd limit the scope of this PR, and wait to see issue pop up in the future. --- clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 4 ++-- clang/test/CIR/CodeGen/vectype-ext.cpp | 8 ++++---- clang/test/CIR/Lowering/vectype.cpp | 11 ++++++----- 3 files changed, 12 insertions(+), 11 deletions(-) diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index 01b9d2535c9d..e8449c6a3f8d 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -1611,7 +1611,7 @@ class CIRVectorCreateLowering assert(vecTy && "result type of cir.vec.create op is not VectorType");

Add new `cir.vtt.address_point` op for visiting the element of VTT to initialize the virtual pointer. 2. Implement `getVirtualBaseClassOffset` method which provides a virtual offset to adjust to actual virtual pointers in virtual base. 3. Follows the original clang CodeGen scheme for the implementation of most other parts. @bcardosolopes's note: this is cherry-picked from an older PR from Jing Zhang and slightly modified for updates: applied review, test, doc and operation syntax. It does not yet has LLVM lowering support, I'm going to make incremental changes on top of this. Any necessary CIR modifications to this design should follow up shortly too. Also, to make this work I also added more logic to `addImplicitStructorParam`s` and `buildThisParam`. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 59 ++++++++ clang/lib/CIR/CodeGen/CIRGenBuilder.h | 13 ++ clang/lib/CIR/CodeGen/CIRGenCXXABI.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenCXXABI.h | 16 ++- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 72 ++++++++-- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenFunction.h | 8 ++ clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 105 +++++++++++++-- clang/lib/CIR/CodeGen/CIRGenModule.h | 5 + clang/lib/CIR/CodeGen/CIRGenVTables.cpp | 127 +++++++++++++++++- clang/lib/CIR/CodeGen/CIRGenVTables.h | 88 +++--------- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 4 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 48 +++++++ clang/test/CIR/CodeGen/vtt.cpp | 125 +++++++++++++++++ 15 files changed, 579 insertions(+), 101 deletions(-) create mode 100644 clang/test/CIR/CodeGen/vtt.cpp diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index c959c7176473..58d6f19ca123 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2399,6 +2399,65 @@ def VTableAddrPointOp : CIR_Op<"vtable.address_point", let hasVerifier = 1; } +//===----------------------------------------------------------------------===// +// VTTAddrPointOp +//===----------------------------------------------------------------------===// + +def VTTAddrPointOp : CIR_Op<"vtt.address_point", + [Pure, DeclareOpInterfaceMethods]> { + let summary = "Get the VTT address point"; + let description = [{ + The `vtt.address_point` operation retrieves an element from the VTT, + which is the address point of a C++ vtable.

Mon Sep 17 00:00:00 2001 From: Guojin Date: Fri, 11 Oct 2024 19:41:56 -0400 Subject: [PATCH 1937/2301] [CIR][CIRGen][Builtin][Neon] Lower neon_vtrn and neon_vtrnq (#942) as title. The generated code is the same as Clang codeden except in a small discrepancy when GEP: OG generates code like this: `%6 = getelementptr inbounds <4 x i16>, ptr %retval.i, i32 1` CIR generates a bit differently: `%6 = getelementptr <4 x i16>, ptr %retval.i, i64 1` Ptr offest might be trivial because choosing i64 over i32 as index type seems to be LLVM Dialect's choice. The lack of `inbounds` keyword might be an issue as `mlir::cir::PtrStrideOp` is currently not lowering to LLVM:GEPOp with `inbounds` attribute as `mlir::cir::PtrStrideOp` itself has no `inbounds`. It's probably because there was no need for it though we do have an implementation of [`CIRGenFunction::buildCheckedInBoundsGEP` ](https://github.com/llvm/clangir/blob/10d6f4b94da7e0181a070f0265d079419d96cf78/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp#L2762). Anyway, the issue is not in the scope of this PR and should be addressed in a separate PR. If we think this is an issue, I can create another PR and probably add optional attribute to `mlir::cir::PtrStrideOp` to achieve it. In addition to lowering work, a couple of more works: 1. Did a little refactoring on variable name changing into desired CamelBack case. 2. Changed neon-misc RUN Options to be consistent with other neon test files and make test case more concise. --- .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 58 +- clang/test/CIR/CodeGen/AArch64/neon-misc.c | 520 +++++++++--------- 2 files changed, 298 insertions(+), 280 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp index f6dad0196e72..645ada341f5e 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp @@ -2973,8 +2973,8 @@ CIRGenFunction::buildAArch64BuiltinExpr(unsigned BuiltinID, const CallExpr *E, } } - mlir::cir::VectorType Ty = GetNeonType(this, Type);

There are two highlights of the PR 1. The PR introduced a new test file to cover neon intrinsics that move data, which is a big category. This would the 5th neon test file. And we're committed to keep total number of neon test files within 6. This file uses another opt option instcombine, which makes test LLVM code more concise, and our -fclangir generated LLVM code would be identical to OG with this. It looks like OG did some instcombine optimization. 2. `getIntFromMLIRValue` helper function could be substituted by [`mlir::cir::IntAttr getConstOpIntAttr` in CIRGenAtomic.cpp](https://github.com/llvm/clangir/blob/24b24557c98d1c031572a567b658cfb6254f8a89/clang/lib/CIR/CodeGen/CIRGenAtomic.cpp#L337). The function `mlir::cir::IntAttr getConstOpIntAttr` is doing more than `getIntFromMLIRValue`, and there is FIXME in the comment, so not sure if we should just use `mlir::cir::IntAttr getConstOpIntAttr`, either is fine with me. --- .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 20 ++ clang/test/CIR/CodeGen/AArch64/neon-ext-mov.c | 215 ++++++++++++++++++ 2 files changed, 235 insertions(+) create mode 100644 clang/test/CIR/CodeGen/AArch64/neon-ext-mov.c diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp index 645ada341f5e..b52c0acbda9d 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp @@ -2195,6 +2195,14 @@ mlir::Value buildNeonCall(unsigned int builtinID, CIRGenFunction &cgf, } } +/// Get integer from a mlir::Value that is an int constant or a constant op. +static int64_t getIntValueFromConstOp(mlir::Value val) { + auto constOp = mlir::cast(val.getDefiningOp()); + return (mlir::cast(constOp.getValue())) + .getValue() + .getSExtValue(); +} + mlir::Value CIRGenFunction::buildCommonNeonBuiltinExpr( unsigned builtinID, unsigned llvmIntrinsic, unsigned altLLVMIntrinsic, const char *nameHint, unsigned modifier, const CallExpr *e, @@ -2239,6 +2247,18 @@ mlir::Value CIRGenFunction::buildCommonNeonBuiltinExpr( // In CIR, integral cast op supports vector of int type truncating. return builder.createIntCast(ops[0], ty); } + case NEON::BI__builtin_neon_vext_v: + case NEON::BI__builtin_neon_vextq_v: { + int cv = getIntValueFromConstOp(ops[2]); + llvm::SmallVector indices; + for (unsigned i = 0, e = vTy.getSize(); i != e; ++i) + indices.push_back(i + cv); + + ops[0] = builder.createBitcast(ops[0], ty); + ops[1] = builder.createBitcast(ops[1], ty); + return builder.createVecShuffle(getLoc(e->getExprLoc()), ops[0], ops[1], + indices); + } } // This second switch is for the intrinsics that might have a more generic diff --git a/clang/test/CIR/CodeGen/AArch64/neon-ext-mov.c b/clang/test/CIR/CodeGen/AArch64/neon-ext-mov.c new file mode 100644 index 000000000000..bbaf896e5a32 --- /dev/null +++ b/clang/test/CIR/CodeGen/AArch64/neon-ext-mov.c @@ -0,0 +1,215 @@ +// RUN: %clang_cc1 -triple aarch64-none-linux-android24 -target-feature +neon \ +// RUN: -fclangir -disable-O0-optnone -fno-clangir-call-conv-lowering \ +// RUN: -flax-vector-conversions=none -emit-cir -o %t.cir %s +// RUN: FileCheck --check-prefix=CIR --input-file=%t.cir %s + +// RUN: %clang_cc1 -triple aarch64-none-linux-android24 -target-feature +neon \ +// RUN: -fclangir -disable-O0-optnone -fno-clangir-call-conv-lowering \ +// RUN: -flax-vector-conversions=none -emit-llvm -o - %s \ +// RUN: | opt -S -passes=instcombine,mem2reg,simplifycfg -o %t.ll +// RUN: FileCheck --check-prefix=LLVM --input-file=%t.ll %s + +// REQUIRES: aarch64-registered-target || arm-registered-target + +// This test file contains test cases for the intrinsics that move data between +// registers and vectors, such as mov, get, set, and ext.

And it has some problems handling the multiple dimension array as above issue shows so that the generated values are not in the same shape with the original array. the new algorithm here is, full fill the values ahead of time with the correct element size and full fill the values to different slots and we only need to maintain the index to write. I feel the new version has better performance (avoid allocation) and better readability slightly. --- clang/lib/CIR/Lowering/LoweringHelpers.cpp | 107 +++++++++------------ clang/test/CIR/Lowering/multi-array.c | 36 +++++++ 2 files changed, 81 insertions(+), 62 deletions(-) create mode 100644 clang/test/CIR/Lowering/multi-array.c diff --git a/clang/lib/CIR/Lowering/LoweringHelpers.cpp b/clang/lib/CIR/Lowering/LoweringHelpers.cpp index 06c92ae12472..3d5dae642cff 100644 --- a/clang/lib/CIR/Lowering/LoweringHelpers.cpp +++ b/clang/lib/CIR/Lowering/LoweringHelpers.cpp @@ -45,84 +45,67 @@ template <> mlir::APFloat getZeroInitFromType(mlir::Type Ty) { llvm_unreachable("NYI");

Currently, those builtins just are treated as LibraryCall or some other ways which eventually get failure, and failure messages are confusing. This PR address this problem by refactoring `CIRGenFunction::buildBuiltinExpr` to keep the same skeleton as OG counterpart `CodeGenFunction::EmitBuiltinExpr`, and add builtin name to NYI message --- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 1175 ++++++++++++++++++----- 1 file changed, 955 insertions(+), 220 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index 59dce4184c5e..6692e63f6b90 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -390,6 +390,9 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, ConstAlways = true; break; } + case Builtin::BI__builtin_fmaf16: + llvm_unreachable("Builtin::BI__builtin_fmaf16 NYI"); + break; default: break; } @@ -435,6 +438,36 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, if (GenerateIntrinsics) { switch (BuiltinIDIfNoAsmLabel) { + case Builtin::BIacos: + case Builtin::BIacosf: + case Builtin::BIacosl: + case Builtin::BI__builtin_acos: + case Builtin::BI__builtin_acosf: + case Builtin::BI__builtin_acosf16: + case Builtin::BI__builtin_acosl: + case Builtin::BI__builtin_acosf128: + llvm_unreachable("Builtin::BIacos like NYI"); + + case Builtin::BIasin: + case Builtin::BIasinf: + case Builtin::BIasinl: + case Builtin::BI__builtin_asin: + case Builtin::BI__builtin_asinf: + case Builtin::BI__builtin_asinf16: + case Builtin::BI__builtin_asinl: + case Builtin::BI__builtin_asinf128: + llvm_unreachable("Builtin::BIasin like NYI"); + + case Builtin::BIatan: + case Builtin::BIatanf: + case Builtin::BIatanl: + case Builtin::BI__builtin_atan: + case Builtin::BI__builtin_atanf: + case Builtin::BI__builtin_atanf16: + case Builtin::BI__builtin_atanl: + case Builtin::BI__builtin_atanf128: + llvm_unreachable("Builtin::BIatan like NYI"); + case Builtin::BIceil: case Builtin::BIceilf: case Builtin::BIceill: @@ -455,7 +488,7 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, case Builtin::BI__builtin_copysignf16: case Builtin::BI__builtin_copysignf128: - llvm_unreachable("NYI"); + llvm_unreachable("BI__builtin_copysignf16 like NYI"); case Builtin::BIcos: case Builtin::BIcosf: @@ -468,6 +501,16 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, assert(!MissingFeatures::fastMathFlags()); return buildUnaryFPBuiltin(*this, *E); + case Builtin::BIcosh: + case Builtin::BIcoshf: + case Builtin::BIcoshl: + case Builtin::BI__builtin_cosh: + case Builtin::BI__builtin_coshf: + case Builtin::BI__builtin_coshf16: + case Builtin::BI__builtin_coshl: + case Builtin::BI__builtin_coshf128: + llvm_unreachable("Builtin::BIcosh like NYI"); + case Builtin::BIexp: case Builtin::BIexpf: case Builtin::BIexpl: @@ -490,6 +533,13 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, assert(!MissingFeatures::fastMathFlags()); return buildUnaryFPBuiltin(*this, *E); + case Builtin::BI__builtin_exp10: + case Builtin::BI__builtin_exp10f: + case Builtin::BI__builtin_exp10f16: + case Builtin::BI__builtin_exp10l: + case Builtin::BI__builtin_exp10f128: + llvm_unreachable("BI__builtin_exp10 like NYI"); + case Builtin::BIfabs: case Builtin::BIfabsf: case Builtin::BIfabsl: @@ -518,7 +568,7 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, case Builtin::BI__builtin_fmaf16: case Builtin::BI__builtin_fmal: case Builtin::BI__builtin_fmaf128: - llvm_unreachable("NYI"); + llvm_unreachable("Builtin::BIfma like NYI"); case Builtin::BIfmax: case Builtin::BIfmaxf: @@ -531,7 +581,7 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, case Builtin::BI__builtin_fmaxf16: case Builtin::BI__builtin_fmaxf128: - llvm_unreachable("NYI"); + llvm_unreachable("BI__builtin_fmaxf16 like NYI"); case Builtin::BIfmin: case Builtin::BIfminf: @@ -544,7 +594,7 @@ RValue CIRGenFunction::buildBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, case Builtin::BI__builtin_fminf16: case Builtin::BI__builtin_fminf128: - llvm_unreachable("NYI"); + llvm_unreachable("BI__builtin_fminf16 like NYI"); // fmod() is a special-case.

It tests > if the floating-point value, specified by the first argument, falls into > any of data classes, specified by the second argument. I meant to support this by creating IntrinsicCallOp directly. But I can't make it due to https://github.com/llvm/clangir/issues/480 since the return type of the intrinsic will mismatch. So I have to create a new Op for it. But I feel it might not be too bad.

I thought [about it](https://github.com/llvm/clangir/pull/958#issuecomment-2405766921) and I understand adding `cir.bitcast` to circumvent the CIR checks, but I am not sure how we can ignore/drop the bitcast while lowering. I think we can just make the CIR casts correct. I have added a number of lowering tests to verify that the CIR is lowered properly. cc: @sitio-couto @bcardosolopes. --- .../TargetLowering/LowerFunction.cpp | 32 +++- .../CIR/CallConvLowering/AArch64/struct.c | 167 ++++++++++++++++++ .../CIR/CallConvLowering/x86_64/basic.cpp | 32 ++-- 3 files changed, 213 insertions(+), 18 deletions(-) create mode 100644 clang/test/CIR/CallConvLowering/AArch64/struct.c diff --git a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp index dccc52ad635d..fee7a752d7fb 100644 --- a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp +++ b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp @@ -42,6 +42,17 @@ Value buildAddressAtOffset(LowerFunction &LF, Value addr, return addr; } +Value createCoercedBitcast(Value Src, Type DestTy, LowerFunction &CGF) { + auto destPtrTy = PointerType::get(CGF.getRewriter().getContext(), DestTy); + + if (auto load = dyn_cast(Src.getDefiningOp())) + return CGF.getRewriter().create(Src.getLoc(), destPtrTy, + CastKind::bitcast, load.getAddr()); + + return CGF.getRewriter().create(Src.getLoc(), destPtrTy, + CastKind::bitcast, Src); +} + /// Given a struct pointer that we are accessing some number of bytes out of it, /// try to gep into the struct to get at its inner goodness.

They all should just use the same set of annotation related globals including file name string, annotation name string, and arguments. This PR makes sure this is the case. FYI: for the test case we have, OG generates [ code ](https://godbolt.org/z/Ev5Ycoqj1), pretty much the same code except annotation variable names.

The core idea of the patch is to introduce the `cir.case` operation to the language. Then we can get the cases by traversing the body of the `cir.switch` operation easily instead of counting the regions and the attributes. Every `cir.case` operation has a region and now the `cir.switch` has only one region too. But to make the analysis and optimizations easier, I add a new concept `simple form` here. That a simple `cir.switch` operation is: all the `cir.case` operation owned by the `cir.switch` lives in the top level blocks of the `cir.switch` region and there is no other operations except the ending `cir.yield`. This solves the previous `simplified for common-case` vs `general solution` discussion in https://github.com/llvm/clangir/issues/522. After implemented this, I feel the correct answer to it is, we want a general solution for constructing and lowering the operations but we like simple and common case for analysis and optimizations. We just mixed the different phases. For other semantics, see `CIROps.td`. For lowering, we can make it generally by lower the cases one by one and finally lower the switch itself. Although this patch has 1000+ lines of changes, I feel it is relatively neat especially it erases some odd behaviors before. Tested with Spec2017's C benchmarks except 500.perlbench_r. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 210 ++++++++++--- clang/lib/CIR/CodeGen/CIRGenAtomic.cpp | 137 ++++---- clang/lib/CIR/CodeGen/CIRGenFunction.h | 49 +-- clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 285 +++++++++-------- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 293 +++++------------- .../Dialect/Transforms/CIRCanonicalize.cpp | 3 +- .../lib/CIR/Dialect/Transforms/FlattenCFG.cpp | 124 +++++--- .../CIR/Dialect/Transforms/LifetimeCheck.cpp | 14 +- clang/test/CIR/CodeGen/atomic-runtime.cpp | 142 ++++----- clang/test/CIR/CodeGen/goto.cpp | 13 +- clang/test/CIR/CodeGen/switch-gnurange.cpp | 109 ++++--- clang/test/CIR/CodeGen/switch.cpp | 178 ++++++----- clang/test/CIR/IR/invalid.cir | 14 +- clang/test/CIR/IR/switch.cir | 38 +-- clang/test/CIR/Lowering/nested-switch.cpp | 69 +++++ clang/test/CIR/Lowering/switch-while.c | 84 +++++ clang/test/CIR/Lowering/switch.cir | 106 ++++--- clang/test/CIR/Transforms/merge-cleanups.cir | 35 ++- clang/test/CIR/Transforms/switch.cir | 129 ++++---- 19 files changed, 1124 insertions(+), 908 deletions(-) create mode 100644 clang/test/CIR/Lowering/nested-switch.cpp create mode 100644 clang/test/CIR/Lowering/switch-while.c diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 0101b5386391..d5782ebee3fe 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -665,7 +665,7 @@ def StoreOp : CIR_Op<"store", [ def ReturnOp : CIR_Op<"return", [ParentOneOf<["FuncOp", "ScopeOp", "IfOp", "SwitchOp", "DoWhileOp", - "WhileOp", "ForOp"]>, + "WhileOp", "ForOp", "CaseOp"]>, Terminator]> { let summary = "Return from function"; let description = [{ @@ -900,7 +900,7 @@ def ConditionOp : CIR_Op<"condition", [ def YieldOp : CIR_Op<"yield", [ReturnLike, Terminator, ParentOneOf<["IfOp", "ScopeOp", "SwitchOp", "WhileOp", "ForOp", "AwaitOp", "TernaryOp", "GlobalOp", "DoWhileOp", "TryOp", "ArrayCtor", - "ArrayDtor", "CallOp"]>]> { + "ArrayDtor", "CallOp", "CaseOp"]>]> { let summary = "Represents the default branching behaviour of a region"; let description = [{ The `cir.yield` operation terminates regions on different CIR operations, @@ -1819,22 +1819,38 @@ def CaseOpKind : I32EnumAttr< let cppNamespace = "::mlir::cir"; } -def CaseEltValueListAttr : - TypedArrayAttrBase { - let constBuilderCall = ?; -} +def CaseOp : CIR_Op<"case", [ + DeclareOpInterfaceMethods, + RecursivelySpeculatable, AutomaticAllocationScope]> { + let summary = "Case operation"; + let description = [{ + The `cir.case` operation represents a case within a C/C++ switch. + The `cir.case` operation must be in a `cir.switch` operation directly or indirectly. -def CaseAttr : AttrDef { - // FIXME: value should probably be optional for more clear "default" - // representation. - let parameters = (ins "ArrayAttr":$value, "CaseOpKindAttr":$kind); - let mnemonic = "case"; - let assemblyFormat = "`<` struct(params) `>`"; -} + The `cir.case` have 4 kinds: + - `equal, `: equality of the second case operand against the + condition. + - `anyof, [constant-list]`: equals to any of the values in a subsequent + following list. + - `range, [lower-bound, upper-bound]`: the condition is within the closed interval. + - `default`: any other value. + + Each case region must be explicitly terminated. + }]; + + let arguments = (ins ArrayAttr:$value, CaseOpKind:$kind); + let regions = (region AnyRegion:$caseRegion); + + let assemblyFormat = "`(` $kind `,` $value `)` $caseRegion attr-dict"; + + let hasVerifier = 1; -def CaseArrayAttr : - TypedArrayAttrBase { - let constBuilderCall = ?; + let skipDefaultBuilders = 1; + let builders = [ + OpBuilder<(ins "ArrayAttr":$value, + "CaseOpKind":$kind, + "OpBuilder::InsertPoint &":$insertPoint)> + ]; } def SwitchOp : CIR_Op<"switch", @@ -1847,45 +1863,136 @@ def SwitchOp : CIR_Op<"switch", conditionally executing multiple regions of code.

This is a suggestion, so any other ideas are welcome. Several ideas was described in the #995 and basically what I'm trying to do is to generate a clean CIR code without additional `bitcast` operations for function pointers and without mix of lowered and initial function types. Looks like we can not just lower the function type and cast the value since too many operations are involved. For instance, for the next simple code: ``` typedef struct { int a; } S; typedef int (*myfptr)(S); int foo(S s) { return 42 + s.a; } void bar() { myfptr a = foo; } ``` we get the next CIR for the function `bar` , before the calling convention lowering pass: ``` cir.func no_proto @bar() extra(#fn_attr) { %0 = cir.alloca !cir.ptr>, !cir.ptr>>, ["a", init] %1 = cir.get_global @foo : !cir.ptr> cir.store %1, %0 : !cir.ptr>, !cir.ptr>> cir.return } ``` As one can see, first three operations depend on the function type. Once `foo` is lowered, we need to fix `GetGlobalOp`: otherwise the code will fail with the verification error since actual `foo` type (lowered) differs from the one currently expected by the `GetGlobalOp`. First idea would just rewrite only the `GetGlobalOp` and insert a bitcast after, so both `AllocaOp` and `StoreOp` would work witth proper types. Once the code will be more complex, we will need to take care about possible use cases, e.g. if we use arrays, we will need to track array accesses to it as well in order to insert this bitcast every time the array element is needed. One workaround I can think of: we fix the `GetGlobalOp` type and cast from the lowered type to the initial, and cast back before the actual call happens - but it doesn't sound as a good and clean approach (from my point of view, of course). So I suggest to use type converter and rewrite any operation that may deal with function pointers and make sure it has a proper type, and we don't have any unlowered function type in the program after the calling convention lowering pass. I added lowering for `AllocaOp`, `GetGlobalOp`, and split the lowering for `FuncOp` (former `CallConvLoweringPattern`) and lower `CallOp` separately. Frankly speaking, I tried to implement a pattern for each operation, but for some reasons the tests are not passed for windows and macOs in this case - something weird happens inside `applyPatternsAndFold` function. I suspect it's due to two different rewriters used - one in the `LoweringModule` and one in the mentioned function. So I decided to follow the same approach as it's done for the `LoweringPrepare` pass and don't involve this complex rewriting framework. Next I will add a type converter for the struct type, patterns for `ConstantOp` (for const arrays and `GlobalViewAttr`) In the end of the day we'll have (at least I hope so) a clean CIR code without any bitcasts for function pointers. cc @sitio-couto @bcardosolopes --- .../Dialect/Transforms/CallConvLowering.cpp | 126 +++++++++++------- .../test/CIR/CallConvLowering/x86_64/fptrs.c | 18 +++ 2 files changed, 94 insertions(+), 50 deletions(-) create mode 100644 clang/test/CIR/CallConvLowering/x86_64/fptrs.c diff --git a/clang/lib/CIR/Dialect/Transforms/CallConvLowering.cpp b/clang/lib/CIR/Dialect/Transforms/CallConvLowering.cpp index 9026d5135031..9cdd734ef2a5 100644 --- a/clang/lib/CIR/Dialect/Transforms/CallConvLowering.cpp +++ b/clang/lib/CIR/Dialect/Transforms/CallConvLowering.cpp @@ -5,12 +5,12 @@ // SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception // //===----------------------------------------------------------------------===// - #include "TargetLowering/LowerModule.h" #include "mlir/Dialect/LLVMIR/LLVMDialect.h" #include "mlir/IR/BuiltinOps.h" #include "mlir/IR/PatternMatch.h" #include "mlir/Pass/Pass.h" +#include "mlir/Transforms/DialectConversion.h" #include "mlir/Transforms/GreedyPatternRewriteDriver.h" #include "clang/CIR/Dialect/IR/CIRDialect.h" #include "clang/CIR/MissingFeatures.h" @@ -23,50 +23,93 @@ namespace mlir { namespace cir { -//===----------------------------------------------------------------------===// -// Rewrite Patterns -//===----------------------------------------------------------------------===// - -struct CallConvLoweringPattern : public OpRewritePattern { - using OpRewritePattern::OpRewritePattern; +FuncType getFuncPointerTy(mlir::Type typ) { + if (auto ptr = dyn_cast(typ)) + return dyn_cast(ptr.getPointee()); + return {}; +} - LogicalResult matchAndRewrite(FuncOp op, - PatternRewriter &rewriter) const final { - llvm::TimeTraceScope scope("Call Conv Lowering Pass", op.getSymName().str()); +bool isFuncPointerTy(mlir::Type typ) { return (bool)getFuncPointerTy(typ); } - const auto module = op->getParentOfType(); +struct CallConvLowering { - auto modOp = op->getParentOfType(); - std::unique_ptr lowerModule = - createLowerModule(modOp, rewriter); + CallConvLowering(ModuleOp module) + : rewriter(module.getContext()), + lowerModule(createLowerModule(module, rewriter)) {} - // Rewrite function calls before definitions.

Fix that logic to match original CodeGen, which also fixes these errors. It's expected that decls can appear in the deferred decl list multiple times, and CodeGen has to guard against that. In the case that triggered the error, both `CIRGenerator::HandleInlineFunctionDefinition` and CIRGenModule were deferring the declaration. Something else I discovered here is that we emit these functions in the opposite order as regular CodeGen: https://godbolt.org/z/4PrKG7h9b. That might be a meaningful difference worth investigating further.

We want to match this behavior, so we need a cir.undef attr to represent the constant. This change implements the lowering for the new op, which matches how cir.zero is lowered. A follow-up will change CIRGen to use it. It also replaces UndefOf with a ConstantOp of UndefAttr to avoid redundancy.

CIRGen was previously emitting an empty attribute, which got interpreted as constant evaluation failing, resulting in a global variable initializer being emitted. Change to undef to match CodeGen. https://godbolt.org/z/7M9EnEddx has the comparison between current CIRGen vs. original CodeGen; it should match after this lands.

const char *const *multi; } output; }; static const char * const test[] = { "test", }; const struct nested data[] = { { { .multi = test, }, }, { { .single = "hello", }, }, }; ``` ClangIR now failed to recognize `data` as an array since it failed to recognize the initializer for union. This comes from a fundamental difference between CIR and LLVM IR. In LLVM IR, the union is simply a struct with the largest member. So it is fine to have only one init element. But in CIR, the union has the information for all members. So if we only pass a single init element, we may be in trouble. We solve the problem by appending placeholder attribute for the uninitialized fields. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 15 +++++++++ clang/lib/CIR/CodeGen/CIRGenBuilder.h | 3 ++ clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 29 ++++++++++++++-- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 9 +++++ clang/test/CIR/CodeGen/nested-union-array.c | 33 +++++++++++++++++++ clang/test/CIR/CodeGen/union-init.c | 13 ++++---- 6 files changed, 94 insertions(+), 8 deletions(-) create mode 100644 clang/test/CIR/CodeGen/nested-union-array.c diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 058e335928aa..a6a27006f357 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -92,6 +92,21 @@ def CIR_BoolAttr : CIR_Attr<"Bool", "bool", [TypedAttrInterface]> { }]; } +//===----------------------------------------------------------------------===// +// InactiveUnionFieldAttr +//===----------------------------------------------------------------------===// + +def InactiveUnionFieldAttr : CIR_Attr<"InactiveUnionField", "inactive_field", [TypedAttrInterface]> { + let summary = "Attribute to represent an uninitialized field for a union."; + let description = [{ + The InactiveUnionFieldAttr is used to represent an uninitialized field + for a union. + }]; + + let parameters = (ins AttributeSelfTypeParameter<"">:$type); + let assemblyFormat = [{}]; +} + //===----------------------------------------------------------------------===// // ZeroAttr //===----------------------------------------------------------------------===// diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.h b/clang/lib/CIR/CodeGen/CIRGenBuilder.h index a940a7b4dc1e..22e3d56bd78b 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuilder.h +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.h @@ -300,6 +300,9 @@ class CIRGenBuilderTy : public CIRBaseBuilderTy { return true; } + if (mlir::isa(attr)) + return true; + llvm_unreachable("NYI"); } diff --git a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp index c8fa52b70fae..377b3770cae6 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp @@ -378,7 +378,32 @@ mlir::Attribute ConstantAggregateBuilder::buildFrom( CharUnits AlignedSize = Size.alignTo(Align); bool Packed = false; - ArrayRef UnpackedElems = Elems; + ArrayRef UnpackedElems; + + // Fill the init elements for union.

In the original codegen there is no much job is done for the indirect arguments inside the loop in the `EmitFunctionProlog`, and additional alloca is added in the end, in the call for `EmitParamDecl` function. In our case, for the indirect argument (which is a pointer) we replace the original alloca with a new one, and store the pointer in there. And replace all the uses of the old alloca with the load from the new one, i.e. in both cases users works with the pointer to a structure.

As a drive-by, this commit also harmonizes the cir.fp print/parse namespace usage, and adds the constraint of supporting only "CIRFPType"s for cir.fp in tablegen instead of verifying it manually in the parsing logic. --- This commit is based on top of a to-be-upstreamed commit which extends the upstream MLIR float type parsing. Upstream parsing of float type has full capability only through parsing the Builtin Dialect's `FloatAttr`. Thos commit exposes the same capabilities to downstream users. --- This PR should resolve (at least) `GCC-C-execute-ieee-fp-cmp-2` and `GCC-C-execute-ieee-fp-cmp-4`, paving the way to other `GCC-C-execute-ieee-*` tests passing from the SingleSource suite.

To avoid overloading the `cir` namespace too much afterwards, move all symbols whose equivalents live inside the `clang::CodeGen` namespace to a new `clang::CIRGen` namespace, so that we match the original CodeGen's structure more closely. There's some symbols that live under `clang/include/clang/CIR` whose equivalents live in `clang/lib/CodeGen` and are in the `clang::CodeGen` namespace. We have these symbols in a common location since they're also used by lowering, so I've also left them in the `cir` namespace. Those symbols are: - AArch64ABIKind - ABIArgInfo - FnInfoOpts - TypeEvaluationKind - X86AVXABILevel This is a pretty large PR out of necessity. To make it slightly more reviewable, I've split it out into three commits (which will be squashed together when the PR lands): - The first commit manually switches places to the `clang::CIRGen` namespace. This has to be manual because we only want to move things selectively. - The second commit adjusts namespace prefixes to make builds work. I ran https://gist.github.com/smeenai/f4dd441fb61c53e835c4e6057f8c322f to make this change. The script is idempotent, and I added substitutions one at a time and reviewed each one afterwards (using `git diff --color-words=.`) to ensure only intended changes were being made. - The third commit runs `git clang-format`. Because I went one-by-one with all my substitutions and checked each one afterwards, I'm pretty confident in the validity of all the changes (despite the size of the PR). --- clang/include/clang/CIR/CIRGenerator.h | 8 +- clang/lib/CIR/CodeGen/ABIInfo.h | 5 +- clang/lib/CIR/CodeGen/Address.h | 4 +- clang/lib/CIR/CodeGen/CIRAsm.cpp | 20 +-- clang/lib/CIR/CodeGen/CIRGenAtomic.cpp | 32 ++--- clang/lib/CIR/CodeGen/CIRGenBuilder.cpp | 3 +- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 54 ++++---- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 40 +++--- .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 16 +-- clang/lib/CIR/CodeGen/CIRGenBuiltinX86.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenCXX.cpp | 16 +-- clang/lib/CIR/CodeGen/CIRGenCXXABI.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenCXXABI.h | 6 +- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 78 +++++------ clang/lib/CIR/CodeGen/CIRGenCall.h | 4 +- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 58 ++++---- clang/lib/CIR/CodeGen/CIRGenCleanup.cpp | 8 +- clang/lib/CIR/CodeGen/CIRGenCleanup.h | 4 +- clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenCstEmitter.h | 4 +- clang/lib/CIR/CodeGen/CIRGenDebugInfo.h | 4 +- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 52 +++---- clang/lib/CIR/CodeGen/CIRGenDeclCXX.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenException.cpp | 12 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 130 +++++++++--------- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 42 +++--- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 24 ++-- clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp | 18 +-- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 55 ++++---- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 126 ++++++++--------- clang/lib/CIR/CodeGen/CIRGenFunction.h | 26 ++-- clang/lib/CIR/CodeGen/CIRGenFunctionInfo.h | 12 +- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 72 +++++----- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 86 ++++++------ clang/lib/CIR/CodeGen/CIRGenModule.h | 7 +- clang/lib/CIR/CodeGen/CIRGenOpenCL.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.h | 4 +- clang/lib/CIR/CodeGen/CIRGenOpenMPRuntime.cpp | 20 +-- clang/lib/CIR/CodeGen/CIRGenOpenMPRuntime.h | 4 +- clang/lib/CIR/CodeGen/CIRGenPointerAuth.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenRecordLayout.h | 4 +- clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 52 +++---- clang/lib/CIR/CodeGen/CIRGenStmtOpenMP.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenTBAA.h | 4 +- clang/lib/CIR/CodeGen/CIRGenTypeCache.h | 4 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 12 +- clang/lib/CIR/CodeGen/CIRGenTypes.h | 10 +- clang/lib/CIR/CodeGen/CIRGenVTables.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenVTables.h | 4 +- clang/lib/CIR/CodeGen/CIRGenValue.h | 4 +- clang/lib/CIR/CodeGen/CIRGenerator.cpp | 4 +- .../CIR/CodeGen/CIRRecordLayoutBuilder.cpp | 6 +- clang/lib/CIR/CodeGen/ConstantInitBuilder.cpp | 2 +- clang/lib/CIR/CodeGen/ConstantInitBuilder.h | 10 +- clang/lib/CIR/CodeGen/ConstantInitFuture.h | 17 +-- clang/lib/CIR/CodeGen/EHScopeStack.h | 4 +- clang/lib/CIR/CodeGen/TargetInfo.cpp | 86 ++++++------ clang/lib/CIR/CodeGen/TargetInfo.h | 4 +- 60 files changed, 671 insertions(+), 666 deletions(-) diff --git a/clang/include/clang/CIR/CIRGenerator.h b/clang/include/clang/CIR/CIRGenerator.h index 85fed2c926d8..78e6055ca993 100644 --- a/clang/include/clang/CIR/CIRGenerator.h +++ b/clang/include/clang/CIR/CIRGenerator.h @@ -34,12 +34,14 @@ namespace clang { class ASTContext;

This is a large PR, and I've split it out into four commits (that'll be squashed when landing). The first commit changes `mlir::cir` to `cir` everywhere. This was originally done mechanically with: ``` find clang \( -name '*.h' -o -name '*.cpp' -o -name '*.td' \) -print0 | xargs -0 perl -pi -e 's/mlir::cir/cir/g' find clang \( -name '*.h' -o -name '*.cpp' \) -print0 | xargs -0 perl -pi -e 's/::cir/cir/g' find clang \( -name '*.h' -o -name '*.cpp' \) -print0 | xargs -0 perl -0777 -pi -e 's/namespace mlir \{\nnamespace cir \{/namespace cir {/g' find clang \( -name '*.h' -o -name '*.cpp' \) -print0 | xargs -0 perl -0777 -pi -e 's!\} // namespace cir\n\} // namespace mlir!} // namespace cir!g' ``` It then required some manual fixups to address edge cases. Code that lived under `mlir::cir` could refer to the `mlir` namespace without qualification, but after the namespace change, we need to explicitly qualify all our usages. This is done in the second commit via https://gist.github.com/smeenai/996200fd45ad123bbf22b412d59479b6, which is an idempotent script to add all qualifications. I added cases to the script one at a time and reviewed each change afterwards to ensure we were only making the intended modifications, so I feel pretty confident in the end result. I also removed `using namespace llvm` from some headers to avoid conflicts, which in turn required adding some `llvm::` qualifiers as well. The third commit fixes a test, since an error message now contains the mlir namespace. Similar tests in flang also have the namespace in their error messages, so this is an expected change. The fourth change runs `git clang-format`. Unfortunately, that doesn't work for TableGen files, so we'll have a few instances of undesirable formatting left there. I'll look into fixing that as a follow-up. I validated the end result by examining the symbols in the built Clang binary. There's nothing in the `mlir::cir` namespace anymore. https://gist.github.com/smeenai/8438fd01588109fcdbde5c8652781dc0 had the symbols which lived in `cir` and should have moved to `clang::CIRGen`, and I validated that all the symbols were moved, with the exceptions noted in https://github.com/llvm/clangir/pull/1082 and the duplicated symbols noted in https://github.com/llvm/clangir/issues/1025. --- clang/include/clang/CIR/ABIArgInfo.h | 8 +- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 472 +++--- clang/include/clang/CIR/Dialect/IR/CIRAttrs.h | 2 -

From 337da0c3e0141a9d87e7cb233d28e972dbe27e18 Mon Sep 17 00:00:00 2001 From: Shoaib Meenai Date: Fri, 8 Nov 2024 16:35:19 -0800 Subject: [PATCH 2059/2301] [CIR][CIRGen] Change buildX functions to emitX (#1093) The buildX naming convention originated when the CIRGen implementation was planned to be substantially different from original CodeGen. CIRGen is now a much closer adaption of CodeGen, and the emitX to buildX renaming just makes things more confusing, since CodeGen also has some helper functions whose names start with build or Build, so it's not immediately clear which CodeGen function corresponds to a CIRGen buildX function. Rename the buildX functions back to emitX to fix this. This diff was generated mostly mechanically. I searched for all buildX functions in CIRGen and all emitX or buildX functions in CodeGen: ``` rg '\b[Bb]uild[A-Z][A-Za-z0-9_]*\b' clang/lib/CIR/CodeGen -Io | sort -u -o /tmp/buildfuncs rg '\b([Ee]mit|[Bb]uild)[A-Z][A-Za-z0-9_]*\b' clang/lib/CodeGen -Io | sort -u -o /tmp/emitfuncs ``` I used a simple Python script to find corresponding functions: https://gist.github.com/smeenai/02be7ced8564cef5518df72606ec7b19. https://gist.github.com/smeenai/6ffd67be4249c8cebdd7fa99cfa4f13c is the resulting list of correspondences. This isn't 100% accurate because it's not accounting for the files that the functions are present in, but that's pretty unlikely to matter here, so I kept it simple. The buildX functions in CIRGen which correspond to an emitX function in CodeGen should be changed, and the ones which correspond to a BuildX function in CodeGen should not be changed. That leaves some functions without any correspondences, which required a judgement call. I scanned through all those functions, and buildVirtualMethodAttr was the only one that seemed like it shouldn't be changed to emit. I performed the replacement as follows: ``` funcs="$(awk '(/-> [Ee]/ || !/->/) && !/buildVirtualMethodAttr/ { print substr($1, 6) }' /tmp/corrfuncs | paste -sd '|')" find clang/include/clang/CIR clang/lib/CIR/{CodeGen,FrontendAction} \( -name '*.h' -o -name '*.cpp' \) -print0 | \ xargs -0 perl -pi -e "s/\bbuild($funcs)\\b/emit\\1/g" ``` The mechanical changes are in the first commit of this PR. There was a manual fixup required for a token pasting macro in CIRGenExprScalar.cpp, which is the second commit. I then ran `git clang-format`, which is the third commit. (They'll be squashed together when the PR is committed.) --- clang/include/clang/CIR/CIRGenerator.h | 6 +- clang/include/clang/CIR/MissingFeatures.h | 10 +- clang/lib/CIR/CodeGen/CIRAsm.cpp | 58 +- clang/lib/CIR/CodeGen/CIRGenAtomic.cpp | 212 +++-- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 361 ++++---- .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 232 +++-- clang/lib/CIR/CodeGen/CIRGenBuiltinX86.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenCXX.cpp | 44 +- clang/lib/CIR/CodeGen/CIRGenCXXABI.h | 35 +- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 76 +- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 230 +++-- clang/lib/CIR/CodeGen/CIRGenCleanup.cpp | 24 +- clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 116 +-- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 103 ++- clang/lib/CIR/CodeGen/CIRGenDeclCXX.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenException.cpp | 45 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 658 +++++++------- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 211 +++-- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 251 +++--- clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp | 283 +++--- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 42 +- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 445 ++++----- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 115 ++- clang/lib/CIR/CodeGen/CIRGenFunction.h | 841 +++++++++--------- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 147 +-- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 134 +-- clang/lib/CIR/CodeGen/CIRGenModule.h | 71 +- clang/lib/CIR/CodeGen/CIRGenOpenCL.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenOpenCLRuntime.h | 4 +- clang/lib/CIR/CodeGen/CIRGenStmt.cpp | 258 +++--- clang/lib/CIR/CodeGen/CIRGenStmtOpenMP.cpp | 14 +- clang/lib/CIR/CodeGen/CIRGenVTables.cpp | 14 +- clang/lib/CIR/CodeGen/CIRGenVTables.h | 6 +- clang/lib/CIR/CodeGen/CIRGenerator.cpp | 12 +- .../Targets/LoweringPrepareItaniumCXXABI.cpp | 2 +- clang/lib/CIR/FrontendAction/CIRGenAction.cpp | 2 +- 37 files changed, 2524 insertions(+), 2564 deletions(-) diff --git a/clang/include/clang/CIR/CIRGenerator.h b/clang/include/clang/CIR/CIRGenerator.h index 78e6055ca993..f4c30a5e892b 100644 --- a/clang/include/clang/CIR/CIRGenerator.h +++ b/clang/include/clang/CIR/CIRGenerator.h @@ -66,7 +66,7 @@ class CIRGenerator : public clang::ASTConsumer { ~HandlingTopLevelDeclRAII() { unsigned Level = --Self.HandlingTopLevelDecls;

A lot of code has been duplicated from CIRGen into cir/Dialect/Transforms in order to let LP live there, but with more necessary CIRGen features (e.g. EH scope and cleanups) going to be used in LP it doesn't make sense to keep it separate. Add this patch that just refactors LoweringPrepare into the CIRGen directory and give it a handle on the CGM. --- clang/include/clang/CIR/CIRGenerator.h | 1 + clang/include/clang/CIR/CIRToCIRPasses.h | 17 +++++++++------- clang/include/clang/CIR/Dialect/Passes.h | 10 ++++++++-- clang/include/clang/CIR/Dialect/Passes.td | 4 ++-- .../Transforms/LoweringPrepareCXXABI.h | 0 .../Transforms/LoweringPrepareItaniumCXXABI.h | 0 .../CIR/Dialect/Transforms/PassDetail.h | 0 clang/lib/CIR/CodeGen/CIRPasses.cpp | 15 +++++++------- clang/lib/CIR/CodeGen/CMakeLists.txt | 1 + .../LoweringPrepare.cpp | 13 +++++++++--- .../Dialect/Transforms/CIRCanonicalize.cpp | 2 +- .../CIR/Dialect/Transforms/CIRSimplify.cpp | 2 +- .../lib/CIR/Dialect/Transforms/CMakeLists.txt | 1 - clang/lib/CIR/Dialect/Transforms/DropAST.cpp | 2 +- .../lib/CIR/Dialect/Transforms/FlattenCFG.cpp | 2 +- .../lib/CIR/Dialect/Transforms/GotoSolver.cpp | 4 ++-- .../CIR/Dialect/Transforms/HoistAllocas.cpp | 4 ++-- .../Dialect/Transforms/IdiomRecognizer.cpp | 2 +- clang/lib/CIR/Dialect/Transforms/LibOpt.cpp | 2 +- .../CIR/Dialect/Transforms/LifetimeCheck.cpp | 3 +-- .../lib/CIR/Dialect/Transforms/SCFPrepare.cpp | 2 +- clang/lib/CIR/Dialect/Transforms/StdHelpers.h | 2 +- .../Targets/LoweringPrepareAArch64CXXABI.cpp | 2 +- .../Targets/LoweringPrepareItaniumCXXABI.cpp | 2 +- clang/lib/CIR/FrontendAction/CIRGenAction.cpp | 20 ++++++++++--------- clang/lib/FrontendTool/CMakeLists.txt | 1 + 26 files changed, 67 insertions(+), 47 deletions(-) rename clang/{lib => include/clang}/CIR/Dialect/Transforms/LoweringPrepareCXXABI.h (100%) rename clang/{lib => include/clang}/CIR/Dialect/Transforms/LoweringPrepareItaniumCXXABI.h (100%) rename clang/{lib => include/clang}/CIR/Dialect/Transforms/PassDetail.h (100%) rename clang/lib/CIR/{Dialect/Transforms => CodeGen}/LoweringPrepare.cpp (99%) diff --git a/clang/include/clang/CIR/CIRGenerator.h b/clang/include/clang/CIR/CIRGenerator.h index f4c30a5e892b..52738824bef4 100644 --- a/clang/include/clang/CIR/CIRGenerator.h +++ b/clang/include/clang/CIR/CIRGenerator.h @@ -98,6 +98,7 @@ class CIRGenerator : public clang::ASTConsumer { std::unique_ptr takeContext() { return std::move(mlirCtx);

Two test cases from OG CodeGen are reused. `str_literals.cl` is the primary test, while `printf.cl` is the bonus one. --- .../CIR/Dialect/Builder/CIRBaseBuilder.h | 13 +++-- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 5 +- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 12 ++-- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 42 ++++++++------ clang/test/CIR/CodeGen/OpenCL/printf.cl | 55 +++++++++++++++++++ clang/test/CIR/CodeGen/OpenCL/str_literals.cl | 23 ++++++++ clang/test/CodeGenOpenCL/printf.cl | 1 + 7 files changed, 120 insertions(+), 31 deletions(-) create mode 100644 clang/test/CIR/CodeGen/OpenCL/printf.cl create mode 100644 clang/test/CIR/CodeGen/OpenCL/str_literals.cl diff --git a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h index 76a4c7174f25..c8b9a0a03cbf 100644 --- a/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h +++ b/clang/include/clang/CIR/Dialect/Builder/CIRBaseBuilder.h @@ -375,13 +375,17 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { return createAlloca(loc, addrType, type, name, alignmentIntAttr); } - mlir::Value createGetGlobal(cir::GlobalOp global, bool threadLocal = false) { + mlir::Value createGetGlobal(mlir::Location loc, cir::GlobalOp global, + bool threadLocal = false) { return create( - global.getLoc(), - getPointerTo(global.getSymType(), global.getAddrSpaceAttr()), + loc, getPointerTo(global.getSymType(), global.getAddrSpaceAttr()), global.getName(), threadLocal); } + mlir::Value createGetGlobal(cir::GlobalOp global, bool threadLocal = false) { + return createGetGlobal(global.getLoc(), global, threadLocal); + } + /// Create a copy with inferred length. cir::CopyOp createCopy(mlir::Value dst, mlir::Value src, bool isVolatile = false) { @@ -547,8 +551,7 @@ class CIRBaseBuilderTy : public mlir::OpBuilder { }); if (last != block->rend()) - return OpBuilder::InsertPoint(block, - ++mlir::Block::iterator(&*last)); + return OpBuilder::InsertPoint(block, ++mlir::Block::iterator(&*last)); return OpBuilder::InsertPoint(block, block->begin()); }; diff --git a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp index ba2d4b1f185f..fc0dbfa4d751 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExpr.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExpr.cpp @@ -1842,12 +1842,9 @@ LValue CIRGenFunction::emitStringLiteralLValue(const StringLiteral *E) { auto g = dyn_cast(cstGlobal); assert(g && "unaware of other symbol providers"); - auto ptrTy = - cir::PointerType::get(CGM.getBuilder().getContext(), g.getSymType()); assert(g.getAlignment() && "expected alignment for string literal"); auto align = *g.getAlignment(); - auto addr = builder.create(getLoc(E->getSourceRange()), - ptrTy, g.getSymName()); + auto addr = builder.createGetGlobal(getLoc(E->getSourceRange()), g); return makeAddrLValue( Address(addr, g.getSymType(), CharUnits::fromQuantity(align)), E->getType(), AlignmentSource::Decl); diff --git a/clang/lib/CIR/CodeGen/CIRGenModule.cpp b/clang/lib/CIR/CodeGen/CIRGenModule.cpp index a1b1e9293c48..939d4dc40433 100644 --- a/clang/lib/CIR/CodeGen/CIRGenModule.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenModule.cpp @@ -1480,15 +1480,14 @@ static cir::GlobalOp generateStringLiteral(mlir::Location loc, mlir::TypedAttr C, cir::GlobalLinkageKind LT, CIRGenModule &CGM, StringRef GlobalName, CharUnits Alignment) { - unsigned AddrSpace = CGM.getASTContext().getTargetAddressSpace( - CGM.getGlobalConstantAddressSpace()); - assert((AddrSpace == 0 && !cir::MissingFeatures::addressSpaceInGlobalVar()) && - "NYI"); + cir::AddressSpaceAttr addrSpaceAttr = + CGM.getBuilder().getAddrSpaceAttr(CGM.getGlobalConstantAddressSpace()); // Create a global variable for this string // FIXME(cir): check for insertion point in module level. auto GV = CIRGenModule::createGlobalOp(CGM, loc, GlobalName, C.getType(), - !CGM.getLangOpts().WritableStrings); + !CGM.getLangOpts().WritableStrings, + addrSpaceAttr); // Set up extra information and add to the module GV.setAlignmentAttr(CGM.getSize(Alignment)); @@ -1559,7 +1558,8 @@ CIRGenModule::getAddrOfConstantStringFromLiteral(const StringLiteral *S, auto ArrayTy = mlir::dyn_cast(GV.getSymType()); assert(ArrayTy && "String literal must be array"); - auto PtrTy = cir::PointerType::get(&getMLIRContext(), ArrayTy.getEltType()); + auto PtrTy = + getBuilder().getPointerTo(ArrayTy.getEltType(), GV.getAddrSpaceAttr()); return builder.getGlobalViewAttr(PtrTy, GV); } diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index 82cdb0e21666..1d2fb1036b36 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -347,6 +347,19 @@ void lowerAnnotationValue( } } +// Get addrspace by converting a pointer type. +// TODO: The approach here is a little hacky.

Comparing to `EmitBinaryAtomicPost`, `buildBinaryAtomicPost` is more concise as OG's ``EmitBinaryAtomicPost`` duplicates quite a bit of code from [MakeBinaryAtomicValue](https://github.com/llvm/clangir/blob/dbf320e5c3db0410566ae561067c595308870bad/clang/lib/CodeGen/CGBuiltin.cpp#L340) Also, didn't implement invert as __sync_add_and_fetch does not need it, but will add it (which is a trivial work) when we implement a builtin that needs it. Test cases are from [OG](https://github.com/llvm/clangir/blob/dbf320e5c3db0410566ae561067c595308870bad/clang/test/CodeGen/Atomics.c#L134) --- clang/include/clang/CIR/MissingFeatures.h | 1 + clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 34 ++++++++- clang/test/CIR/CodeGen/atomic.cpp | 91 +++++++++++++++++++++++ 3 files changed, 124 insertions(+), 2 deletions(-) diff --git a/clang/include/clang/CIR/MissingFeatures.h b/clang/include/clang/CIR/MissingFeatures.h index b9f81fcd3e22..cb720ad800d8 100644 --- a/clang/include/clang/CIR/MissingFeatures.h +++ b/clang/include/clang/CIR/MissingFeatures.h @@ -229,6 +229,7 @@ struct MissingFeatures { static bool emitConstrainedFPCall() { return false; } static bool emitEmptyRecordCheck() { return false; } static bool isPPC_FP128Ty() { return false; } + static bool emitBinaryAtomicPostHasInvert() { return false; } // Inline assembly static bool asmGoto() { return false; } diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index 21fd90819ced..04f2c1861401 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -244,6 +244,7 @@ static Address checkAtomicAlignment(CIRGenFunction &CGF, const CallExpr *E) { /// and the expression node. static mlir::Value makeBinaryAtomicValue( CIRGenFunction &cgf, cir::AtomicFetchKind kind, const CallExpr *expr, + mlir::Value *neededValP = nullptr, mlir::Type *neededValT = nullptr, cir::MemOrder ordering = cir::MemOrder::SequentiallyConsistent) { QualType typ = expr->getType(); @@ -263,7 +264,15 @@ static mlir::Value makeBinaryAtomicValue( mlir::Value val = cgf.emitScalarExpr(expr->getArg(1)); mlir::Type valueType = val.getType(); val = emitToInt(cgf, val, typ, intType); - + // These output arguments are needed for post atomic fetch operations + // that calculate the result of the operation as return value of + // _and_fetch builtins.

The original approach creates a new global op and copies every attribute from the old one. But just `setSymType` should work well. This also removes missing feature flags there. --- clang/include/clang/CIR/MissingFeatures.h | 1 - clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 17 ++--------------- clang/test/CIR/CodeGen/stmtexpr-init.c | 4 ++-- 3 files changed, 4 insertions(+), 18 deletions(-) diff --git a/clang/include/clang/CIR/MissingFeatures.h b/clang/include/clang/CIR/MissingFeatures.h index cb720ad800d8..b25c5e07f9f0 100644 --- a/clang/include/clang/CIR/MissingFeatures.h +++ b/clang/include/clang/CIR/MissingFeatures.h @@ -68,7 +68,6 @@ struct MissingFeatures { // Address space related static bool addressSpace() { return false; } - static bool addressSpaceInGlobalVar() { return false; } // Clang codegen options static bool strictVTablePointers() { return false; } diff --git a/clang/lib/CIR/CodeGen/CIRGenDecl.cpp b/clang/lib/CIR/CodeGen/CIRGenDecl.cpp index e6bcb0d6bf04..6fa387483492 100644 --- a/clang/lib/CIR/CodeGen/CIRGenDecl.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenDecl.cpp @@ -575,19 +575,7 @@ cir::GlobalOp CIRGenFunction::addInitializerToStaticVarDecl( // because some types, like unions, can't be completely represented // in the LLVM type system.) if (GV.getSymType() != Init.getType()) { - cir::GlobalOp OldGV = GV; - GV = builder.createGlobal(CGM.getModule(), getLoc(D.getSourceRange()), - OldGV.getName(), Init.getType(), - OldGV.getConstant(), GV.getLinkage()); - // FIXME(cir): OG codegen inserts new GV before old one, we probably don't - // need that? - GV.setVisibility(OldGV.getVisibility()); - GV.setGlobalVisibilityAttr(OldGV.getGlobalVisibilityAttr()); - GV.setInitialValueAttr(Init); - GV.setTlsModelAttr(OldGV.getTlsModelAttr()); - assert(!cir::MissingFeatures::setDSOLocal()); - assert(!cir::MissingFeatures::setComdat()); - assert(!cir::MissingFeatures::addressSpaceInGlobalVar()); + GV.setSymType(Init.getType()); // Normally this should be done with a call to CGM.replaceGlobal(OldGV, GV), // but since at this point the current block hasn't been really attached, @@ -595,8 +583,7 @@ cir::GlobalOp CIRGenFunction::addInitializerToStaticVarDecl( // Given those constraints, thread in the GetGlobalOp and update it // directly.

It's basically some `mlir-tablegen`-builtin magic: With `constBuilderCall` specified, we can apply `DefaultValuedAttr` with any default value we can construct from constant values. Then we can easily omit the default in assembly. Hence, we don't need to compromise anything for the wrapper attribute `cir::VisibilityAttr`. Similarly to #1009, an empty literal ``` `` ``` is used to omit the leading space emitted by inner attribute. The test case `visibility-attribute.c` is modified to save the intermediate CIR to disk and reflect the effects. Double whitespaces in other test files are removed. --- clang/include/clang/CIR/Dialect/IR/CIRAttrs.td | 3 +++ clang/include/clang/CIR/Dialect/IR/CIROps.td | 7 +++++-- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 13 ------------- clang/test/CIR/CallConvLowering/AArch64/struct.c | 4 ++-- clang/test/CIR/CodeGen/AArch64/neon-arith.c | 6 +++--- clang/test/CIR/CodeGen/annotations-var.c | 4 ++-- clang/test/CIR/CodeGen/array-init.c | 2 +- .../CIR/CodeGen/attribute-annotate-multiple.cpp | 6 +++--- clang/test/CIR/CodeGen/cxx1z-inline-variables.cpp | 14 +++++++------- clang/test/CIR/CodeGen/global-new.cpp | 4 ++-- clang/test/CIR/CodeGen/globals-neg-index-array.c | 4 ++-- clang/test/CIR/CodeGen/kr-func-promote.c | 2 +- clang/test/CIR/CodeGen/member-init-struct.cpp | 2 +- clang/test/CIR/CodeGen/no-pie.c | 2 +- clang/test/CIR/CodeGen/paren-list-init.cpp | 4 ++-- clang/test/CIR/CodeGen/static-vars.cpp | 2 +- clang/test/CIR/CodeGen/temporaries.cpp | 10 +++++----- clang/test/CIR/CodeGen/tempref.cpp | 8 ++++---- clang/test/CIR/CodeGen/unary-deref.cpp | 2 +- clang/test/CIR/CodeGen/union-init.c | 2 +- clang/test/CIR/CodeGen/visibility-attribute.c | 6 ++++-- clang/test/CIR/IR/annotations.cir | 2 +- clang/test/CIR/IR/invalid-annotations.cir | 2 +- clang/test/CIR/Lowering/brcond.cir | 2 +- clang/test/CIR/Lowering/store-memcpy.cpp | 2 +- 25 files changed, 55 insertions(+), 60 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index c931b9376287..463bdd5cec7a 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -1016,6 +1016,9 @@ def VisibilityAttr : CIR_Attr<"Visibility", "visibility"> { let skipDefaultBuilders = 1; + // Make DefaultValuedAttr accept VisibilityKind as default value ($0). + let constBuilderCall = "cir::VisibilityAttr::get($_builder.getContext(), $0)"; + let extraClassDeclaration = [{ bool isDefault() const { return getValue() == VisibilityKind::Default; }; bool isHidden() const { return getValue() == VisibilityKind::Hidden; }; diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index a829e1c99d79..975a3ff6c8bd 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2387,7 +2387,10 @@ def GlobalOp : CIR_Op<"global", // TODO: sym_visibility can possibly be represented by implementing the // necessary Symbol's interface in terms of linkage instead. let arguments = (ins SymbolNameAttr:$sym_name, - VisibilityAttr:$global_visibility, + DefaultValuedAttr< + VisibilityAttr, + "VisibilityKind::Default" + >:$global_visibility, OptionalAttr:$sym_visibility, TypeAttr:$sym_type, Arg:$linkage, @@ -2405,7 +2408,7 @@ def GlobalOp : CIR_Op<"global", let regions = (region AnyRegion:$ctorRegion, AnyRegion:$dtorRegion); let assemblyFormat = [{ ($sym_visibility^)? - custom($global_visibility) + (`` $global_visibility^)?

Previously, the if/else and scope regions could be left completely empty which is non-trivially expected in most code inspecting these ops. This led, for example, to a crash when and if clause was left empty in the source code. Now, the child regions must be terminated, either explicitly or implicitly by the default builder and assembly parser. This change improves the clarity and correctness of the code. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 44 ++++++++++++------- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 37 +++++++++++----- .../Dialect/Transforms/CIRCanonicalize.cpp | 6 +-- .../lib/CIR/Dialect/Transforms/FlattenCFG.cpp | 6 ++- .../Lowering/ThroughMLIR/LowerCIRToMLIR.cpp | 4 +- clang/test/CIR/CodeGen/OpenMP/parallel.cpp | 2 - clang/test/CIR/CodeGen/if-constexpr.cpp | 3 -- clang/test/CIR/CodeGen/stmt-expr.c | 5 +-- clang/test/CIR/Lowering/if.cir | 34 ++++++++++++++ 9 files changed, 101 insertions(+), 40 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 975a3ff6c8bd..61b02d50e90d 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -750,8 +750,10 @@ def IfOp : CIR_Op<"if", } ``` - `cir.if` defines no values and the 'else' can be omitted. `cir.yield` must - explicitly terminate the region if it has more than one block. + `cir.if` defines no values and the 'else' can be omitted.

This patch literally implement https://github.com/llvm/llvm-project/blob/d233fedfb0de882353c348cd1ac57dab619efa6d/clang/lib/CodeGen/Targets/X86.cpp#L3015-L3240 in CIR. There some differences due to the traditional pipeline are converting AST to LLVM and we're transforming CIR to CIR. And also to get the ABI Info, I moved `X86_64ABIInfo` to the header. --- clang/include/clang/CIR/ABIArgInfo.h | 2 + .../CIR/Dialect/Builder/CIRBaseBuilder.h | 11 + clang/include/clang/CIR/Dialect/IR/CIROps.td | 20 + .../Dialect/Transforms/LoweringPrepare.cpp | 9 +- .../Transforms/LoweringPrepareCXXABI.h | 1 + .../Transforms/LoweringPrepareX86ABI.h | 0 .../Transforms/TargetLowering/ABIInfoImpl.cpp | 12 + .../Transforms/TargetLowering/ABIInfoImpl.h | 3 + .../Transforms/TargetLowering/CIRCXXABI.h | 19 - .../Transforms/TargetLowering/CMakeLists.txt | 1 + .../TargetLowering/ItaniumCXXABI.cpp | 1 + .../Targets/LoweringPrepareX86CXXABI.cpp | 357 ++++++++++++++++++ .../Transforms/TargetLowering/Targets/X86.cpp | 92 +---- .../TargetLowering/Targets/X86_64ABIInfo.h | 96 +++++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 34 +- clang/test/CIR/Lowering/var-arg-x86_64.c | 78 ++++ 16 files changed, 624 insertions(+), 112 deletions(-) create mode 100644 clang/lib/CIR/Dialect/Transforms/LoweringPrepareX86ABI.h create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/Targets/LoweringPrepareX86CXXABI.cpp create mode 100644 clang/lib/CIR/Dialect/Transforms/TargetLowering/Targets/X86_64ABIInfo.h create mode 100644 clang/test/CIR/Lowering/var-arg-x86_64.c diff --git a/clang/include/clang/CIR/ABIArgInfo.h b/clang/include/clang/CIR/ABIArgInfo.h index b3c3d68b9572..28215e7ba196 100644 --- a/clang/include/clang/CIR/ABIArgInfo.h +++ b/clang/include/clang/CIR/ABIArgInfo.h @@ -252,6 +252,8 @@ class ABIArgInfo { bool isExpand() const { return TheKind == Expand;

First of all, don't worry - despite the PR seems big, it's basically consist of helpers + refactoring. Also, there is a minor change in the `CIRBaseBuilder` - I made static the `getBestAllocaInsertPoint` method in order to call it from lowering - we discussed once - and I here we just need it (or copy-paste the code, which doesn't seem good).

In CIR we track all the union members, while in LLVM IR only the largest one. And here we need to take this difference into account: we need to find a type of the largest member and treat it as the first (and only) union member in order to preserve all the logic from the original codegen. There is a method `StructType::getLargestMember` - but looks like it produces different results (with the one I implemented or better to say copy-pasted). Maybe it's done intentionally, I don't know. The LLVM IR produced has also some difference from the original one. In the original IR `gep` is emitted - and we can not do the same. If we create `getMemberOp` we may fail on type checking for unions - since the first member type may differ from the largest type. This is why we create `bitcast` instead.

For example, currently we have 86 operations in LowerToLLVM.cpp but only 45 operations under though MLIR. It won't be easy to add proper lowering for all operation to **different** dialects. I think the solution may be to allow **mixed** IR. So that we can lowering CIR to MLIR's standard dialects partially and we can use some existing analysis and optimizations in MLIR and then we can lower all of them (the MLIR dialects and unlowered clangir) to LLVM IR. The hybrid IR is one of the goals of MLIR as far as I know. NOTE: I completely understand that the DirectlyLLVM pipeline is the tier-1 pipeline that we want to support. The idea above won't change this. I just want to offer some oppotunities for the downstream projects and finally some chances to improve the overall ecosystem. --- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 5880 ++++++++--------- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.h | 1024 +++ clang/utils/TableGen/CIRLoweringEmitter.cpp | 33 +- 3 files changed, 3712 insertions(+), 3225 deletions(-) create mode 100644 clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.h diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index 9c5d8b575281..232666939916 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -9,19 +9,15 @@ // This file implements lowering of CIR operations to LLVMIR. // //===----------------------------------------------------------------------===// +#include "LowerToLLVM.h" #include "LoweringHelpers.h" #include "mlir/Conversion/AffineToStandard/AffineToStandard.h" #include "mlir/Conversion/ControlFlowToLLVM/ControlFlowToLLVM.h" -#include "mlir/Conversion/FuncToLLVM/ConvertFuncToLLVM.h" #include "mlir/Conversion/FuncToLLVM/ConvertFuncToLLVMPass.h" -#include "mlir/Conversion/LLVMCommon/TypeConverter.h" #include "mlir/Conversion/ReconcileUnrealizedCasts/ReconcileUnrealizedCasts.h" #include "mlir/Conversion/SCFToControlFlow/SCFToControlFlow.h" #include "mlir/Dialect/DLTI/DLTI.h" #include "mlir/Dialect/Func/IR/FuncOps.h" -#include "mlir/Dialect/LLVMIR/LLVMAttrs.h" -#include "mlir/Dialect/LLVMIR/LLVMDialect.h" -#include "mlir/Dialect/LLVMIR/LLVMTypes.h" #include "mlir/Dialect/LLVMIR/Transforms/Passes.h" #include "mlir/IR/Attributes.h" #include "mlir/IR/Builders.h" @@ -45,11 +41,6 @@ #include "mlir/Target/LLVMIR/Dialect/LLVMIR/LLVMToLLVMIRTranslation.h" #include "mlir/Target/LLVMIR/Dialect/OpenMP/OpenMPToLLVMIRTranslation.h" #include "mlir/Target/LLVMIR/Export.h" -#include "mlir/Transforms/DialectConversion.h" -#include "clang/CIR/Dialect/IR/CIRAttrs.h" -#include "clang/CIR/Dialect/IR/CIRDialect.h" -#include "clang/CIR/Dialect/IR/CIROpsEnums.h" -#include "clang/CIR/Dialect/IR/CIRTypes.h" #include "clang/CIR/Dialect/Passes.h" #include "clang/CIR/LoweringHelpers.h" #include "clang/CIR/MissingFeatures.h" @@ -70,8 +61,6 @@ #include #include -#include "LowerModule.h" - using namespace cir;

Due to missing constraints, a bug in codegen has slipped in which created `cir.cmp` operations with result type that matches the original AST expression type. In C, as opposed to C++, boolean expression types are "int". This resulted with extra operations being codegened around boolean expressions and their usage. This commit both enforces `cir.cmp` in the op definition and fixes the mentioned bug. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 3 +- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 13 +- clang/test/CIR/CodeGen/bf16-ops.c | 289 +++++++++--------- clang/test/CIR/CodeGen/float16-ops.c | 144 ++++----- clang/test/CIR/CodeGen/fp16-ops.c | 72 ++--- clang/test/CIR/IR/invalid.cir | 10 + clang/test/CIR/Lowering/ThroughMLIR/doWhile.c | 79 +++-- clang/test/CIR/Lowering/ThroughMLIR/if.c | 156 +++++----- clang/test/CIR/Lowering/ThroughMLIR/while.c | 109 +++---- clang/test/CIR/Lowering/dot.cir | 12 +- clang/test/CIR/Lowering/goto.cir | 7 +- clang/test/CIR/Lowering/loops-with-break.cir | 47 ++- .../test/CIR/Lowering/loops-with-continue.cir | 47 ++- clang/test/CIR/Lowering/switch.cir | 5 +- clang/test/CIR/Transforms/mem2reg.c | 78 +++-- clang/test/CIR/Transforms/scf-prepare.cir | 33 +- clang/test/CIR/Transforms/simpl.c | 10 +- clang/test/CIR/Transforms/switch.cir | 5 +- 18 files changed, 531 insertions(+), 588 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 8d4ede9958f0..ac3ca72c0c70 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -1268,8 +1268,7 @@ def CmpOp : CIR_Op<"cmp", [Pure, SameTypeOperands]> { ``` }]; - // TODO: get more accurate than CIR_AnyType - let results = (outs CIR_AnyType:$result); + let results = (outs CIR_BoolType:$result); let arguments = (ins Arg:$kind, CIR_AnyType:$lhs, CIR_AnyType:$rhs); diff --git a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp index 6c4441ba0a1c..ee2a0c32cbff 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp @@ -947,12 +947,11 @@ class ScalarExprEmitter : public StmtVisitor { // Other kinds of vectors.

But that merged PR doesn't show in the git log. Maybe the stacked PR may not get successed? But after all, we need to land it again. Following off are original commit messages: --- This is the following of https://github.com/llvm/clangir/pull/1100. After https://github.com/llvm/clangir/pull/1100, when we want to use LongDouble for VAArg, we will be in trouble due to details in X86_64's ABI and this patch tries to address this. The practical impact the patch is, after this patch, with https://github.com/llvm/clangir/pull/1088 and a small following up fix, we can build and run all C's benchmark in SpecCPU 2017.

FIXME in lambda __invoke(): OG simply returns but CIR generates call to llvm.trap. This is just temporary and we will fix in in near future. But I feel I should still list those IRs so once we fix problem with codegen of invoke, we'd get test failure on this one and fix it.

28 Nov 2024 06:41:12 +0800 Subject: [PATCH 2130/2301] [CIR] Remove InavalidUnionFieldAttr and remove a check in array attr (#1166) Close https://github.com/llvm/clangir/issues/1131 This is another solution to https://github.com/llvm/clangir/pull/1160 This patch revert https://github.com/llvm/clangir/pull/1007 and remain its test. The problem described in https://github.com/llvm/clangir/pull/1007 is workaround by skipping the check of equivalent of element types in arrays. We can't mock such checks simply by adding another attribute to `ConstStructAttr` since the types are aggregated. e.g., we have to handle the cases like `struct { union { ... } }` and `struct { struct { union { ... } } }` and so on. To make it, we have to introduce what I called "two type systems" in https://github.com/llvm/clangir/pull/1160. This is not very good giving it removes a reasonable check. But it might not be so problematic since the Sema part has already checked it. (Of course, we still need face the risks to introduce new bugs any way) --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 15 ------ clang/lib/CIR/CodeGen/CIRGenBuilder.h | 3 -- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 28 +--------- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 16 +----- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 8 --- clang/test/CIR/CodeGen/nested-union-array.c | 33 ------------ clang/test/CIR/CodeGen/union-init.c | 13 +++-- clang/test/CIR/IR/invalid.cir | 3 +- clang/test/CIR/Lowering/nested-union-array.c | 28 ++++++++++ .../test/CIR/Lowering/union-in-struct-init.c | 51 +++++++++++++++++++ 10 files changed, 89 insertions(+), 109 deletions(-) delete mode 100644 clang/test/CIR/CodeGen/nested-union-array.c create mode 100644 clang/test/CIR/Lowering/nested-union-array.c create mode 100644 clang/test/CIR/Lowering/union-in-struct-init.c diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index d0ac1d00c4b5..71d8439e175a 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -92,21 +92,6 @@ def CIR_BoolAttr : CIR_Attr<"Bool", "bool", [TypedAttrInterface]> { }]; } -//===----------------------------------------------------------------------===// -// InactiveUnionFieldAttr -//===----------------------------------------------------------------------===// - -def InactiveUnionFieldAttr : CIR_Attr<"InactiveUnionField", "inactive_field", [TypedAttrInterface]> { - let summary = "Attribute to represent an uninitialized field for a union."; - let description = [{ - The InactiveUnionFieldAttr is used to represent an uninitialized field - for a union. - }]; - - let parameters = (ins AttributeSelfTypeParameter<"">:$type); - let assemblyFormat = [{}]; -} - //===----------------------------------------------------------------------===// // ZeroAttr //===----------------------------------------------------------------------===// diff --git a/clang/lib/CIR/CodeGen/CIRGenBuilder.h b/clang/lib/CIR/CodeGen/CIRGenBuilder.h index ea5fb980cc40..28be733f62d7 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuilder.h +++ b/clang/lib/CIR/CodeGen/CIRGenBuilder.h @@ -297,9 +297,6 @@ class CIRGenBuilderTy : public cir::CIRBaseBuilderTy { return true; } - if (mlir::isa(attr)) - return true; - llvm_unreachable("NYI"); } diff --git a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp index deea4159ff36..67eee98667bc 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp @@ -377,31 +377,7 @@ mlir::Attribute ConstantAggregateBuilder::buildFrom( CharUnits AlignedSize = Size.alignTo(Align); bool Packed = false; - ArrayRef UnpackedElems; - - // Fill the init elements for union.

David Olsen Date: Mon, 9 Dec 2024 06:52:25 -0800 Subject: [PATCH 2151/2301] [CIR][NFC] Cleanup: MLIRContext vs ASTContext (#1217) ClangIR CodeGen makes use of both `mlir::MLIRContext` and `clang::ASTContext`. Referring to these as just "context" can be ambiguous. This change attempts to make the CodeGen code more clear by choosing better variable names. The change is almost entirely renaming: mostly change variables, parameters, and fields named `context` or `ctx` to `mlirContext` or `astContext`. There are some other renames having to do with contexts, and a small number of other drive-by fixes. (I considered also renaming functions named `getContext()`, but did not include that in this change.) This is entirely code cleanup. There should be no behavior changes. --- clang/include/clang/CIR/CIRGenerator.h | 8 +- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 22 +-- clang/lib/CIR/CodeGen/CIRGenCXX.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenCXXABI.h | 6 +- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 39 ++--- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 29 ++-- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp | 10 +- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 18 +-- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 24 +-- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 5 +- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 31 ++-- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 151 +++++++++--------- clang/lib/CIR/CodeGen/CIRGenModule.h | 8 +- clang/lib/CIR/CodeGen/CIRGenTBAA.cpp | 21 +-- clang/lib/CIR/CodeGen/CIRGenTBAA.h | 6 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 39 ++--- clang/lib/CIR/CodeGen/CIRGenTypes.h | 4 +- clang/lib/CIR/CodeGen/CIRGenVTables.cpp | 16 +- clang/lib/CIR/CodeGen/CIRGenValue.h | 10 +- clang/lib/CIR/CodeGen/CIRGenerator.cpp | 36 +++-- clang/lib/CIR/CodeGen/CIRPasses.cpp | 14 +- clang/lib/CIR/CodeGen/ConstantInitBuilder.cpp | 4 +- clang/lib/CIR/CodeGen/ConstantInitBuilder.h | 22 +-- 25 files changed, 281 insertions(+), 264 deletions(-) diff --git a/clang/include/clang/CIR/CIRGenerator.h b/clang/include/clang/CIR/CIRGenerator.h index f121d2c453d7..cb702aa978fa 100644 --- a/clang/include/clang/CIR/CIRGenerator.h +++ b/clang/include/clang/CIR/CIRGenerator.h @@ -45,7 +45,7 @@ namespace cir { class CIRGenerator : public clang::ASTConsumer { virtual void anchor(); clang::DiagnosticsEngine &Diags; - clang::ASTContext *astCtx; + clang::ASTContext *astContext; llvm::IntrusiveRefCntPtr fs; // Only used for debug info. @@ -71,7 +71,7 @@ class CIRGenerator : public clang::ASTConsumer { }; protected: - std::unique_ptr mlirCtx; + std::unique_ptr mlirContext; std::unique_ptr CGM; private: @@ -86,7 +86,7 @@ class CIRGenerator : public clang::ASTConsumer { bool EmitFunction(const clang::FunctionDecl *FD); bool HandleTopLevelDecl(clang::DeclGroupRef D) override; - void HandleTranslationUnit(clang::ASTContext &Ctx) override; + void HandleTranslationUnit(clang::ASTContext &astContext) override; void HandleInlineFunctionDefinition(clang::FunctionDecl *D) override; void HandleTagDeclDefinition(clang::TagDecl *D) override; void HandleTagDeclRequiredDefinition(const clang::TagDecl *D) override; @@ -96,7 +96,7 @@ class CIRGenerator : public clang::ASTConsumer { mlir::ModuleOp getModule(); std::unique_ptr takeContext() { - return std::move(mlirCtx); + return std::move(mlirContext); }; bool verifyModule(); diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index d7bd1f745f3a..47c4d3dc0f18 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -154,12 +154,12 @@ struct WidthAndSignedness { } // namespace static WidthAndSignedness -getIntegerWidthAndSignedness(const clang::ASTContext &context, +getIntegerWidthAndSignedness(const clang::ASTContext &astContext, const clang::QualType Type) { assert(Type->isIntegerType() && "Given type is not an integer."); unsigned Width = Type->isBooleanType() ?

It is slightly verbose due to the difference between LLVM and CIR's type system. LLVM's pointer are opaque types while CIR's pointer are typed.

Some tests are updated with triple and DLTI attribute eliminated (replaced by an option in RUN line). But still some tests remain unchanged, primarily because they use `cir-opt` instead. --- clang/test/CIR/Lowering/address-space.cir | 7 +- clang/test/CIR/Lowering/data-member.cir | 4 +-

In order for this to work, we need to use LINK_COMPONENTS instead of LINK_LIBS for all LLVM dependencies, and clang_target_link_libraries for all Clang dependencies, so that they get rewritten to use the dylib. Remove llvm_update_compile_flags while I'm here, since the build macros handle that internally. Before this change, we'd link against certain LLVM libraries both statically and dynamically, leading to test failures from duplicate singletons. The way this works for MLIR is fragile right now: MLIR can create its own dylib as well but doesn't have build system support for linking against that dylib. We end up folding the MLIR libraries into libclang-cpp.so (because all Clang dependencies get pulled into it), but MLIR tools still link the MLIR libraries statically. It'll still work, but BUILD_SHARED_LIBS is possibly a better alternative for development. Distributions like Fedora build their LLVM packages with LLVM_LINK_LLVM_DYLIB, so we'll want to eventually have good MLIR support for that setup too. --- .../Transforms/TargetLowering/CMakeLists.txt | 4 ++- clang/tools/cir-opt/CMakeLists.txt | 27 +++++++++-------- clang/tools/cir-translate/CMakeLists.txt | 29 +++++++++---------- 3 files changed, 30 insertions(+), 30 deletions(-) diff --git a/clang/lib/CIR/Dialect/Transforms/TargetLowering/CMakeLists.txt b/clang/lib/CIR/Dialect/Transforms/TargetLowering/CMakeLists.txt index d3cb9fc96f1a..21bfa30a111a 100644 --- a/clang/lib/CIR/Dialect/Transforms/TargetLowering/CMakeLists.txt +++ b/clang/lib/CIR/Dialect/Transforms/TargetLowering/CMakeLists.txt @@ -22,10 +22,12 @@ add_clang_library(TargetLowering DEPENDS clangBasic + LINK_COMPONENTS + TargetParser + LINK_LIBS PUBLIC clangBasic - LLVMTargetParser MLIRIR MLIRPass MLIRDLTIDialect diff --git a/clang/tools/cir-opt/CMakeLists.txt b/clang/tools/cir-opt/CMakeLists.txt index 741cdfa5950d..900697ffe8e4 100644 --- a/clang/tools/cir-opt/CMakeLists.txt +++ b/clang/tools/cir-opt/CMakeLists.txt @@ -4,15 +4,24 @@ get_property(conversion_libs GLOBAL PROPERTY MLIR_CONVERSION_LIBS) include_directories(${LLVM_MAIN_SRC_DIR}/../mlir/include) include_directories(${CMAKE_BINARY_DIR}/tools/mlir/include) -set(LIBS - ${dialect_libs} - ${conversion_libs} +add_clang_tool(cir-opt + cir-opt.cpp +) + +clang_target_link_libraries(cir-opt + PRIVATE clangCIR clangCIRLoweringThroughMLIR clangCIRLoweringDirectToLLVM - MLIRAnalysis MLIRCIR MLIRCIRTransforms +) + +target_link_libraries(cir-opt + PRIVATE + ${dialect_libs} + ${conversion_libs} + MLIRAnalysis MLIRDialect MLIRIR MLIRMemRefDialect @@ -23,13 +32,3 @@ set(LIBS MLIRTransforms MLIRTransformUtils ) - -add_clang_tool(cir-opt - cir-opt.cpp - - DEPENDS - ${LIBS} -) - -target_link_libraries(cir-opt PRIVATE ${LIBS}) -llvm_update_compile_flags(cir-opt) diff --git a/clang/tools/cir-translate/CMakeLists.txt b/clang/tools/cir-translate/CMakeLists.txt index a5e22b02e505..21834799ea82 100644 --- a/clang/tools/cir-translate/CMakeLists.txt +++ b/clang/tools/cir-translate/CMakeLists.txt @@ -5,15 +5,24 @@ get_property(translation_libs GLOBAL PROPERTY MLIR_TRANSLATION_LIBS) include_directories(${LLVM_MAIN_SRC_DIR}/../mlir/include) include_directories(${CMAKE_BINARY_DIR}/tools/mlir/include) -set(LIBS - ${dialect_libs} - ${conversion_libs} - ${translation_libs} +add_clang_tool(cir-translate + cir-translate.cpp +) + +clang_target_link_libraries(cir-translate + PRIVATE clangCIR clangCIRLoweringDirectToLLVM - MLIRAnalysis MLIRCIR MLIRCIRTransforms +) + +target_link_libraries(cir-translate + PRIVATE + ${dialect_libs} + ${conversion_libs} + ${translation_libs} + MLIRAnalysis MLIRDialect MLIRIR MLIROptLib @@ -24,13 +33,3 @@ set(LIBS MLIRTranslateLib MLIRSupport ) - -add_clang_tool(cir-translate - cir-translate.cpp - - DEPENDS - ${LIBS} -) - -target_link_libraries(cir-translate PRIVATE ${LIBS}) -llvm_update_compile_flags(cir-translate) From 4af8e298f9fe48c03fa49557b2f7d4289c00b9a4 Mon Sep 17 00:00:00 2001 From: Ronan Keryell Date: Thu, 12 Dec 2024 10:02:04 -0800 Subject: [PATCH 2164/2301] [CIR] Remove the !cir.void return type for functions returning void (#1203) C/C++ functions returning void had an explicit !cir.void return type while not having any returned value, which was breaking a lot of MLIR invariants when the CIR dialect is used in a greater context, for example with the inliner. Now, a C/C++ function returning void has not return type and no return values, which does not break the MLIR invariant about the same number of return types and returned values.

This is similar with the previous analysis only approach I proposed, where we may not care about the lowered code. And this is what I described as layering problems in https://discourse.llvm.org/t/rfc-a-clangir-based-safe-c/83245 This is similar with the other issue proposed https://github.com/llvm/clangir/issues/1128. We'd better to emit the higher level operations and lowering/optimizing it later. This is also inspired our handling method for VAArg, where we use ABI information to lower things during the passes. It gives me more confidence that I am doing things right. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 15 ++++++++++++++ clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 10 ++++++++-- .../Dialect/Transforms/LoweringPrepare.cpp | 20 +++++++++++++++++-- .../Transforms/LoweringPrepareCXXABI.h | 4 ++++ .../Transforms/LoweringPrepareItaniumCXXABI.h | 12 +++++++++++ .../TargetLowering/ItaniumCXXABI.cpp | 3 +++ clang/test/CIR/CodeGen/delete-array.cpp | 8 ++++++++ 7 files changed, 68 insertions(+), 4 deletions(-) create mode 100644 clang/test/CIR/CodeGen/delete-array.cpp diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index b86861999330..798a1718abe9 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -3555,6 +3555,21 @@ def LLVMIntrinsicCallOp : CIR_Op<"llvm.intrinsic"> { } +//===----------------------------------------------------------------------===// +// DeleteArrayOp +//===----------------------------------------------------------------------===// + +def DeleteArrayOp : CIR_Op<"delete.array">, + Arguments<(ins CIR_PointerType:$address)> { + let summary = "Delete address representing an array"; + let description = [{ + `cir.delete.array` operation deletes an array.

int foo() { return 42; } void bar() { A a; int b = foo(); } ``` The call to `foo` guarded by the synthetic `tryOp` looks approximately like the following: ``` cir.try synthetic cleanup { %2 = cir.call exception @_Z3foov() : () -> !s32i cleanup { cir.call @_ZN1AD1Ev(%0) : (!cir.ptr) -> () extra(#fn_attr1) // call to destructor of 'A' cir.yield } cir.yield } catch [#cir.unwind { cir.resume }] cir.store %2, %1: !s32i, !cir.ptr // CIR verification error ``` The result of the `foo` call is in the `try` region - and is not accessible from the outside, so the code generation fails with `operand #0 does not dominate its use` . #### Solution So we have several options how to handle this properly. 1. We may intpoduce a new operation here, like `TryCall` but probably more high level one, e.g. introduce the `InvokeOp`. 2. Also, we may add the result to `TryOp`. 3. The fast fix that is implemented in this PR is a temporary `alloca` where we store the call result right in the try region. And the result of the whole `emitCall` is a `load` from the temp `alloca`. So this PR is both the request for changes and an open discussion as well - how to handle this properly. So far I choose the third approach. If it's ok - I will need to create one more PR with a similar fix for the aggregated results or update this one. --- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 23 ++++++++++++++++ clang/test/CIR/CodeGen/try-catch-dtors.cpp | 31 ++++++++++++++++++++++ 2 files changed, 54 insertions(+) diff --git a/clang/lib/CIR/CodeGen/CIRGenCall.cpp b/clang/lib/CIR/CodeGen/CIRGenCall.cpp index 6e31e2f41311..45bcdbf40cee 100644 --- a/clang/lib/CIR/CodeGen/CIRGenCall.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenCall.cpp @@ -552,6 +552,17 @@ static cir::CIRCallOpInterface emitCallLikeOp( extraFnAttrs); } +static RValue getRValueThroughMemory(mlir::Location loc, + CIRGenBuilderTy &builder, mlir::Value val, + Address addr) { + auto ip = builder.saveInsertionPoint(); + builder.setInsertionPointAfterValue(val); + builder.createStore(loc, val, addr); + builder.restoreInsertionPoint(ip); + auto load = builder.createLoad(loc, addr); + return RValue::get(load); +} + RValue CIRGenFunction::emitCall(const CIRGenFunctionInfo &CallInfo, const CIRGenCallee &Callee, ReturnValueSlot ReturnValue, @@ -890,6 +901,18 @@ RValue CIRGenFunction::emitCall(const CIRGenFunctionInfo &CallInfo, auto Results = theCall->getOpResults(); assert(Results.size() <= 1 && "multiple returns NYI"); assert(Results[0].getType() == RetCIRTy && "Bitcast support NYI"); + + mlir::Region *region = builder.getBlock()->getParent(); + if (region != theCall->getParentRegion()) { + Address DestPtr = ReturnValue.getValue(); + + if (!DestPtr.isValid()) + DestPtr = CreateMemTemp(RetTy, callLoc, "tmp.try.call.res"); + + return getRValueThroughMemory(callLoc, builder, Results[0], + DestPtr); + } + return RValue::get(Results[0]); } default: diff --git a/clang/test/CIR/CodeGen/try-catch-dtors.cpp b/clang/test/CIR/CodeGen/try-catch-dtors.cpp index 40c35434e17c..5cf0bf0a1a0b 100644 --- a/clang/test/CIR/CodeGen/try-catch-dtors.cpp +++ b/clang/test/CIR/CodeGen/try-catch-dtors.cpp @@ -308,3 +308,34 @@ void yo2(bool x) { // CIR: } catch [type #cir.all { // CIR: cir.catch_param -> !cir.ptr // CIR: }] + + +int foo() { return 42; } + +struct A { + ~A() {} +}; + +void bar() { + A a; + int b = foo(); +} + +// CIR-LABEL: @_Z3barv +// CIR: %[[V0:.*]] = cir.alloca !ty_A, !cir.ptr, ["a"] {alignment = 1 : i64} +// CIR: %[[V1:.*]] = cir.alloca !s32i, !cir.ptr, ["b", init] {alignment = 4 : i64} +// CIR: %[[V2:.*]] = cir.alloca !s32i, !cir.ptr, ["tmp.try.call.res"] {alignment = 4 : i64} +// CIR: cir.try synthetic cleanup { +// CIR: %[[V4:.*]] = cir.call exception @_Z3foov() : () -> !s32i cleanup { +// CIR: cir.call @_ZN1AD2Ev(%[[V0]]) : (!cir.ptr) -> () extra(#fn_attr) +// CIR: cir.yield +// CIR: } +// CIR: cir.store %[[V4]], %[[V2]] : !s32i, !cir.ptr +// CIR: cir.yield +// CIR: } catch [#cir.unwind { +// CIR: cir.resume +// CIR: }] +// CIR: %[[V3:.*]] = cir.load %[[V2]] : !cir.ptr, !s32i +// CIR: cir.store %[[V3]], %[[V1]] : !s32i, !cir.ptr +// CIR: cir.call @_ZN1AD2Ev(%[[V0]]) : (!cir.ptr) -> () extra(#fn_attr) +// CIR: cir.return From d5d99020bf536a9e705efac111558544e83caae3 Mon Sep 17 00:00:00 2001 From: Sirui Mu Date: Wed, 18 Dec 2024 04:26:21 +0800 Subject: [PATCH 2174/2301] [CIR] Put loop body in nested scopes (#1221) This PR puts for-loop body, while-loop body, and do-while-loop body in nested scopes.

Guojin Date: Tue, 17 Dec 2024 17:25:19 -0500 Subject: [PATCH 2175/2301] [CIR][Dialect] Add FMaximumOp and FMinimumOp (#1237) There are two sets of intrinsics regarding Min and Max operations for floating points [Maximum](https://mlir.llvm.org/docs/Dialects/LLVM/#llvmintrmaximum-llvmmaximumop) vs [Maxnum](https://mlir.llvm.org/docs/Dialects/LLVM/#llvmintrmaxnum-llvmmaxnumop) [Minimum](https://mlir.llvm.org/docs/Dialects/LLVM/#llvmintrminimum-llvmminimumop) vs [Minnum](https://mlir.llvm.org/docs/Dialects/LLVM/#llvmintrminnum-llvmminnumop) [The difference is whether NaN should be propagated when one of the inputs is NaN](https://llvm.org/docs/LangRef.html#llvm-maximumnum-intrinsic) Maxnum and Minnum would return number if one of inputs is NaN, and the other is a number, But Maximum and Minimum would return NaN (propagation of NaN) And they are resolved to different ASM such as [FMAX](https://developer.arm.com/documentation/ddi0596/2021-03/SIMD-FP-Instructions/FMAX--vector---Floating-point-Maximum--vector--?lang=en) vs [FMAXNM](https://developer.arm.com/documentation/ddi0596/2021-03/SIMD-FP-Instructions/FMAXNM--vector---Floating-point-Maximum-Number--vector--?lang=en) Both have user cases, we already implemented Maxnum and Minnum But Maximum and Minimum has user cases in [neon intrinsic ](https://developer.arm.com/architectures/instruction-sets/intrinsics/vmax_f32 ) and [__builtin_elementwise_maximum ](https://github.com/llvm/clangir/blob/a989ecb2c55da1fe28e4072c31af025cba6c4f0f/clang/test/CodeGen/strictfp-elementwise-bulitins.cpp#L53) --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 6 ++--

As a side note for brainstorm, it might be worth in the future for CIR to introduce Vector Across type operations even though LLVM dialect doesn't have it yet.

Specifically, it enables TableGen support for the `-gen-cir-tbaa-name-lowering` option, allowing for the generation of `getTBAAName` functions based on the `tbaaName`. This enhancement enables us to replace the hardcoded TBAA names in the `getTypeName` function with the newly generated `getTBAAName`. --- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 14 ++++-- .../clang/CIR/Dialect/IR/CMakeLists.txt | 4 ++ .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 19 ++++---- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.h | 4 ++ clang/utils/TableGen/CIRLoweringEmitter.cpp | 44 +++++++++++++++++++ clang/utils/TableGen/TableGen.cpp | 6 +++ clang/utils/TableGen/TableGenBackends.h | 2 + 7 files changed, 80 insertions(+), 13 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIRTypes.td b/clang/include/clang/CIR/Dialect/IR/CIRTypes.td index 68b27a053176..37810b6886df 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRTypes.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRTypes.td @@ -20,13 +20,18 @@ include "mlir/Interfaces/DataLayoutInterfaces.td" include "mlir/IR/AttrTypeBase.td" include "mlir/IR/EnumAttr.td" +// Specify the TBAA name of CIR_type +class TBAALoweringInfo { + string tbaaName = ""; +} + //===----------------------------------------------------------------------===// // CIR Types //===----------------------------------------------------------------------===// class CIR_Type traits = [], string baseCppClass = "::mlir::Type"> - : TypeDef { + : TypeDef, TBAALoweringInfo { let mnemonic = typeMnemonic; } @@ -162,6 +167,7 @@ class CIR_FloatType ]> {} def CIR_Single : CIR_FloatType<"Single", "float"> { + let tbaaName = "float"; let summary = "CIR single-precision float type"; let description = [{ Floating-point type that represents the `float` type in C/C++.

Previously we just set a new type and it worked. But recently I started to test ClangIR with CSmith in order to find some run time bugs and faced with the next problem. ``` typedef struct { int x : 15; uint8_t y; } S; S g = { -12, 254}; int main() { printf("%d\n", g.y); return 0; } ``` The output for this program is ... 127 but not 254! The reason is that first global var is created with the type of struct `S`, then `get_member` operation is generated with index `1` and then after, the type of the global is rewritten - I assume because of the anon struct created on the right side in the initialization. But the `get_member` operation still wants to access to the field at index `1` and get a wrong byte. If we change the `y` type to `int` we will fail on the verification stage. But in the example above it's a run time error! This is why I suggest to add a bitcast once we have to rewrite the global type. --- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 7 +++++++ clang/test/CIR/CodeGen/bitfields.c | 18 ++++++++++++++++++ 2 files changed, 25 insertions(+) diff --git a/clang/lib/CIR/CodeGen/CIRGenModule.cpp b/clang/lib/CIR/CodeGen/CIRGenModule.cpp index 81d60477cae0..2a2557f1fdda 100644 --- a/clang/lib/CIR/CodeGen/CIRGenModule.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenModule.cpp @@ -814,6 +814,13 @@ void CIRGenModule::replaceGlobal(cir::GlobalOp Old, cir::GlobalOp New) { auto UseOpResultValue = GGO.getAddr();

This dramatically simplifies the lowering logic of most operations and the lowered code itself as it naturally uses `i1` for anything boolean. The change involves separating between type lowering when scalars are involved and when memory is involved. This is a pattern that was inspired by clang's codegen which directly emits `i1` from the AST without intermediate higher level representation like CIR has. This also paves the way to more complex lowerings that are implemented in clang codegen through the three primitives added here: `Convert Type For Memory`, `Emit For Memory` and `Emit To Memory`. They are used in clang for non-trivial types like bitints but also extensible vectors. --- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 2 +- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 297 +++++++++++------- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.h | 54 +++- .../ThroughMLIR/LowerCIRLoopToSCF.cpp | 5 +- .../Lowering/ThroughMLIR/LowerCIRToMLIR.cpp | 123 +++++--- clang/test/CIR/CodeGen/atomic-xchg-field.c | 8 +- clang/test/CIR/CodeGen/bf16-ops.c | 10 +- clang/test/CIR/CodeGen/builtin-assume.cpp | 4 +- clang/test/CIR/CodeGen/builtin-constant-p.c | 3 +- clang/test/CIR/CodeGen/complex-arithmetic.c | 9 +- clang/test/CIR/CodeGen/complex-cast.c | 8 +- clang/test/CIR/CodeGen/globals.cpp | 4 + clang/test/CIR/CodeGen/new-null.cpp | 2 +- .../CodeGen/pointer-to-data-member-cast.cpp | 8 +- clang/test/CIR/CodeGen/static.cpp | 4 +- clang/test/CIR/IR/invalid.cir | 6 +- clang/test/CIR/Lowering/ThroughMLIR/bool.cir | 5 +- .../test/CIR/Lowering/ThroughMLIR/branch.cir | 14 +- clang/test/CIR/Lowering/ThroughMLIR/cast.cir | 32 +- clang/test/CIR/Lowering/ThroughMLIR/cmp.cpp | 15 +- clang/test/CIR/Lowering/ThroughMLIR/doWhile.c | 12 +- clang/test/CIR/Lowering/ThroughMLIR/if.c | 16 +- .../test/CIR/Lowering/ThroughMLIR/tenary.cir | 6 +- clang/test/CIR/Lowering/ThroughMLIR/while.c | 12 +- clang/test/CIR/Lowering/binop-overflow.cir | 20 +- clang/test/CIR/Lowering/bool.cir | 9 +- clang/test/CIR/Lowering/branch.cir | 22 +- clang/test/CIR/Lowering/brcond.cir | 25 +- clang/test/CIR/Lowering/cast.cir | 16 +- clang/test/CIR/Lowering/const-array.cir | 5 + clang/test/CIR/Lowering/const.cir | 7 +- clang/test/CIR/Lowering/loadstorealloca.cir | 20 +- clang/test/CIR/Lowering/ptrstride.cir | 10 + clang/test/CIR/Lowering/select.cir | 24 +- clang/test/CIR/Lowering/struct.cir | 19 ++ clang/test/CIR/Lowering/unary-not.cir | 24 +- clang/test/CIR/Lowering/unions.cir | 3 +- 37 files changed, 516 insertions(+), 347 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenModule.cpp b/clang/lib/CIR/CodeGen/CIRGenModule.cpp index b35ef11c7782..085e2c237ee7 100644 --- a/clang/lib/CIR/CodeGen/CIRGenModule.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenModule.cpp @@ -820,7 +820,7 @@ void CIRGenModule::replaceGlobal(cir::GlobalOp Old, cir::GlobalOp New) { mlir::Type ptrTy = builder.getPointerTo(OldTy); mlir::Value cast = builder.createBitcast(GGO->getLoc(), UseOpResultValue, ptrTy); - UseOpResultValue.replaceAllUsesExcept(cast, {cast.getDefiningOp()}); + UseOpResultValue.replaceAllUsesExcept(cast, cast.getDefiningOp()); } } } diff --git a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp index 79d4cf7301ac..6a321fca58f1 100644 --- a/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp +++ b/clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp @@ -349,12 +349,81 @@ unsigned getGlobalOpTargetAddrSpace(mlir::ConversionPatternRewriter &rewriter, .getAddressSpace(); } +/// Given a type convertor and a data layout, convert the given type to a type +/// that is suitable for memory operations.

From 2f71d042fc75a7449859cd25c376bbd9cad27b8c Mon Sep 17 00:00:00 2001 From: Chuanqi Xu Date: Mon, 6 Jan 2025 22:54:12 +0800 Subject: [PATCH 2190/2301] [CIR][CIRGen] Improve emission for array of unions (#1236) Close https://github.com/llvm/clangir/issues/1185 The patch itself seems slightly ad-hoc. As the issue tracked by https://github.com/llvm/clangir/issues/1178, the fundamental solution may be to introduce two type systems to solve the inconsistent semantics for Union between LLVM IR and CIR. This will be great to handle other inconsistent semantics between LLVM IR and CIR if any. Back to the patch itself, although the code looks not good initially to me too. But I feel it may be a good workaround since clang/test/CIR/Lowering/union-array.c is an example for array of unions directly and clang/test/CIR/Lowering/nested-union-array.c gives an example for array of unions indirectly (array of structs which contain unions). So I feel we've already covered all the cases.

This way of OG's implementation is quite unnecessary IMHO, this is MAX, not ADD or MUL. After all, using the expected type as return type of intrinsic call produces [the same ASM code](https://godbolt.org/z/3nKG7fxPb). --- .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 32 +++++++++++-- clang/test/CIR/CodeGen/AArch64/neon-misc.c | 48 +++++++++++++++++++ 2 files changed, 76 insertions(+), 4 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp index 82f8b82495df..0153ca8b4643 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp @@ -2349,6 +2349,26 @@ emitCommonNeonCallPattern0(CIRGenFunction &cgf, llvm::StringRef intrincsName, return builder.createBitcast(res, resultType); } +/// The function `emitCommonNeonVecAcrossCall` implements a common way +/// to implement neon intrinsic which has the following pattern: +/// 1.

Now it's time to fix the layout for the const structs. There is a divergence between const structs generated by CIR and the original codegen. And this PR makes one more step to eliminate it. There are cases where the extra padding is required - and here is a fix for some of them. I did not write extra tests, since the fixes in the existing already covers the code I added. The point is that now the layout for all of these structs in the LLVM IR with and without CIR is the same. --- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 66 ++++++++++++++++++++--- clang/lib/CIR/CodeGen/CIRGenModule.h | 50 +++++++++++++++++ clang/test/CIR/CodeGen/bitfields.c | 6 +-- clang/test/CIR/CodeGen/const-bitfields.c | 4 +- clang/test/CIR/CodeGen/struct.c | 5 +- 5 files changed, 118 insertions(+), 13 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp index 3eb8627084f4..ecdcd2066fb0 100644 --- a/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenExprConst.cpp @@ -43,6 +43,19 @@ using namespace clang::CIRGen;

This embarrassment of duplication needed to be fixed, along with cleaning up other functions that convert from Clang types to ClangIR types. The three functions `CIRGenFunction::ConvertType`, `CIRGenFunction::convertType`, and `CIRGenFunction::getCIRType` were combined into a single function `CIRGenFunction::convertType`. Other functions were renamed as follows: - `CIRGenTypes::ConvertType` to `CIRGenTypes::convertType` - `CIRGenTypes::ConvertFunctionTypeInternal` to `CIRGenTypes::convertFunctionTypeInternal` - `CIRGenModule::getCIRType` to `CIRGenModule::convertType` - `ConstExprEmitter::ConvertType` to `ConstExprEmitter::convertType` - `ScalarExprEmitter::ConvertType` to `ScalarExprEmitter::convertType` Many cases of `getTypes().convertType(t)` and `getTypes().convertTypeForMem(t)` were changed to just `convertType(t)` and `convertTypeForMem(t)`, respectively, because the forwarding functions in `CIRGenModule` and `CIRGenFunction` make the explicit call to `getTypes()` unnecessary. --- clang/lib/CIR/CodeGen/CIRAsm.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp | 44 +++++------ .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenCall.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenCoroutine.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 6 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 33 ++++---- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 4 +- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 10 +-- clang/lib/CIR/CodeGen/CIRGenExprComplex.cpp | 12 +-- clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 31 ++++---- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 78 +++++++++---------- clang/lib/CIR/CodeGen/CIRGenFunction.cpp | 19 ++--- clang/lib/CIR/CodeGen/CIRGenFunction.h | 10 +-- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 15 ++-- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 15 ++-- clang/lib/CIR/CodeGen/CIRGenModule.h | 2 +- clang/lib/CIR/CodeGen/CIRGenOpenCL.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 26 +++---- clang/lib/CIR/CodeGen/CIRGenTypes.h | 6 +- clang/lib/CIR/CodeGen/TargetInfo.cpp | 16 ++-- 22 files changed, 162 insertions(+), 185 deletions(-) diff --git a/clang/lib/CIR/CodeGen/CIRAsm.cpp b/clang/lib/CIR/CodeGen/CIRAsm.cpp index a20e75e07423..2513b92e8010 100644 --- a/clang/lib/CIR/CodeGen/CIRAsm.cpp +++ b/clang/lib/CIR/CodeGen/CIRAsm.cpp @@ -455,7 +455,7 @@ mlir::LogicalResult CIRGenFunction::emitAsmStmt(const AsmStmt &S) { uint64_t InputSize = getContext().getTypeSize(InputTy); if (getContext().getTypeSize(OutputType) < InputSize) { // Form the asm to return the value as a larger integer or fp type. - ResultRegTypes.back() = ConvertType(InputTy); + ResultRegTypes.back() = convertType(InputTy); } } if (mlir::Type AdjTy = getTargetHooks().adjustInlineAsmType( @@ -478,7 +478,7 @@ mlir::LogicalResult CIRGenFunction::emitAsmStmt(const AsmStmt &S) { // Otherwise there will be a mis-match if the matrix is also an // input-argument which is represented as vector. if (isa(OutExpr->getType().getCanonicalType())) - DestAddr = DestAddr.withElementType(ConvertType(OutExpr->getType())); + DestAddr = DestAddr.withElementType(convertType(OutExpr->getType())); ArgTypes.push_back(DestAddr.getType()); ArgElemTypes.push_back(DestAddr.getElementType()); diff --git a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp index 93c919134c21..bb285e4811e3 100644 --- a/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenBuiltin.cpp @@ -72,7 +72,7 @@ static RValue emitUnaryFPBuiltin(CIRGenFunction &CGF, const CallExpr &E) { template static RValue emitUnaryMaybeConstrainedFPToIntBuiltin(CIRGenFunction &CGF, const CallExpr &E) { - auto ResultType = CGF.ConvertType(E.getType()); + auto ResultType = CGF.convertType(E.getType()); auto Src = CGF.emitScalarExpr(E.getArg(0)); if (CGF.getBuilder().getIsFPConstrained()) @@ -88,7 +88,7 @@ static RValue emitBinaryFPBuiltin(CIRGenFunction &CGF, const CallExpr &E) { auto Arg1 = CGF.emitScalarExpr(E.getArg(1)); auto Loc = CGF.getLoc(E.getExprLoc()); - auto Ty = CGF.ConvertType(E.getType()); + auto Ty = CGF.convertType(E.getType()); auto Call = CGF.getBuilder().create(Loc, Ty, Arg0, Arg1); return RValue::get(Call->getResult(0)); @@ -101,7 +101,7 @@ static mlir::Value emitBinaryMaybeConstrainedFPBuiltin(CIRGenFunction &CGF, auto Arg1 = CGF.emitScalarExpr(E.getArg(1)); auto Loc = CGF.getLoc(E.getExprLoc()); - auto Ty = CGF.ConvertType(E.getType()); + auto Ty = CGF.convertType(E.getType()); if (CGF.getBuilder().getIsFPConstrained()) { CIRGenFunction::CIRGenFPOptionsRAII FPOptsRAII(CGF, &E); @@ -122,7 +122,7 @@ emitBuiltinBitOp(CIRGenFunction &CGF, const CallExpr *E, else arg = CGF.emitScalarExpr(E->getArg(0)); - auto resultTy = CGF.ConvertType(E->getType()); + auto resultTy = CGF.convertType(E->getType()); auto op = CGF.getBuilder().create(CGF.getLoc(E->getExprLoc()), resultTy, arg); return RValue::get(op); @@ -415,7 +415,7 @@ RValue CIRGenFunction::emitBuiltinExpr(const GlobalDecl GD, unsigned BuiltinID, // of the type.

Now, a C/C++ function returning void has no return type and no return values, which does not break the MLIR invariant about the same number of return types and returned values. This change does not keeps the same parsing/pretty-printed syntax as before for compatibility like in https://github.com/llvm/clangir/pull/1203 because it requires some new features from the MLIR parser infrastructure itself, which is not great. This uses an optional type for function return type. The default MLIR parser for optional parameters requires an optional anchor we do not have in the syntax, so use a custom FuncType parser to handle the optional return type. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 13 ++- .../include/clang/CIR/Dialect/IR/CIRTypes.td | 25 +++-- clang/lib/CIR/CodeGen/CIRGenTypes.cpp | 2 +- clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 14 +-- clang/lib/CIR/Dialect/IR/CIRTypes.cpp | 94 ++++++++++++++++--- .../Transforms/TargetLowering/LowerTypes.cpp | 2 +- clang/test/CIR/CodeGen/fun-ptr.c | 6 +- clang/test/CIR/CodeGen/gnu-extension.c | 2 +- clang/test/CIR/CodeGen/member-init-struct.cpp | 8 +- clang/test/CIR/CodeGen/multi-vtable.cpp | 4 +- clang/test/CIR/CodeGen/no-proto-fun-ptr.c | 14 +-- clang/test/CIR/CodeGen/pointer-arith-ext.c | 8 +- .../CIR/CodeGen/pointer-to-member-func.cpp | 16 ++-- clang/test/CIR/CodeGen/static.cpp | 14 +-- clang/test/CIR/IR/being_and_nothingness.cir | 28 ++++++ 15 files changed, 182 insertions(+), 68 deletions(-) create mode 100644 clang/test/CIR/IR/being_and_nothingness.cir diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index 2e4c707c895c..dfcc836756d1 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -3474,8 +3474,6 @@ def FuncOp : CIR_Op<"func", [ /// Returns the results types that the callable region produces when /// executed. llvm::ArrayRef getCallableResults() { - if (::llvm::isa(getFunctionType().getReturnType())) - return {}; return getFunctionType().getReturnTypes(); } @@ -3492,10 +3490,15 @@ def FuncOp : CIR_Op<"func", [ } /// Returns the argument types of this function. - llvm::ArrayRef getArgumentTypes() { return getFunctionType().getInputs(); } + llvm::ArrayRef getArgumentTypes() { + return getFunctionType().getInputs(); + } - /// Returns the result types of this function. - llvm::ArrayRef getResultTypes() { return getFunctionType().getReturnTypes(); } + /// Returns 0 or 1 result type of this function (0 in the case of a function + /// returing void) + llvm::ArrayRef getResultTypes() { + return getFunctionType().getReturnTypes(); + } /// Hook for OpTrait::FunctionOpInterfaceTrait, called after verifying that /// the 'type' attribute is present and checks if it holds a function type. diff --git a/clang/include/clang/CIR/Dialect/IR/CIRTypes.td b/clang/include/clang/CIR/Dialect/IR/CIRTypes.td index c805b6887cf3..53ea393abe3f 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRTypes.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRTypes.td @@ -372,29 +372,38 @@ def CIR_VectorType : CIR_Type<"Vector", "vector", def CIR_FuncType : CIR_Type<"Func", "func"> { let summary = "CIR function type"; let description = [{ - The `!cir.func` is a function type.

The previous discussion is here #1281 The idea is to add a notion about padding in the `StructType` in the same fashion as it's done for packed structures - as a bool argument in the constructor. Now we can compute the proper union type size as a size of the largest element + size of padding type. There are some downsides though - I had to add this `padded` word in many places. So take a look please!

And this PR is not a small one, so I need to apologize. But looks like there is a problem that may affect the run time. ### Problem Consider the next code: ``` #include typedef struct { int f0 : 24; int f1; int f2; } S; static S g1 = {2799, 9, 123}; static int *g2 = &g1.f2; int main() { printf("check: %d\n",*g2); return 0; } ``` This program dumps anything but not `123`. So basically we don't support global variables that refer to another globals in the case of aggregate types. This PR fixes global views for two cases: structs and array of structs (see the tests). There is an issue with unions too, but I think we will discuss it later, once we will agree on the approach ### Some details For the example above, `g1` variable is created in two steps: 1) The variable is created with the `S` type. In our case it's `!cir.struct x 3>, !cir.int, !cir.int}`(which differs from the OG btw, and may be I need to take a look at the bit fields again - but it's not a problem right now) 2) For the left side we create anon structure of type ` !cir.struct, !cir.int, !cir.int, !cir.int, !cir.int, !cir.int}>` which is the same as in OG and then `g1` is replaced with the new type. Basically the same happens in the OG. But then the `replaceAllUsesWith` solves all the possible problems. In our case we can not do it this easy. The `g2` is: ``` cir.global @g2 = #cir.global_view<@g1, [2 : i32]> : !cir.ptr ``` The problem is in the indexes! After `g1` is replaced, the index in `g2`'s `GlobalViewAttr`still points to the old type!!! So we have to create a new `GlobalViewAttr` with new indexes! ### Solution My solution is based on the `computeGlobalViewIndicesFromFlatOffset` function from `CIRGenBuilder` that is basically a mapping from indexes to offset. I compute an offset and then map it back to the indexes with for the new type. May be there is a better solution though, have some ideas? #### Implementation details Most of the changes are in the `CIRGenModule` where we do the replacement. Also, there are some changes in `CIRGenBuilder` - I moved `computeGlobalViewIndicesFromFlatOffset` to `cpp` with no changes and added the opposite function `computeOffsetFromGlobalViewIndices`. One more fix is more important - is about `GlobalViewAttr` indexes generation for vtable. I suggest we don't set the first index to zero in CIR and add it in the lowering - in this case we can do it uniformly as ``` if (isa(sourceType)) indices.push_back(0); ``` The previous approach was not completely correct - we have to add the leading zero index for the anon structures as well: ``` if (stTy.isIdentified()) indices.push_back(0); // Wrong ``` Thus, there are some changes in tests as well. It's not an unrelated issue - we have to fix it - either now or as a separated PR that should come before this one. Also, I added tests with the covered cases with the original LLVM IR, just for comparison - so there are some divergences as well. Finally - this code was already tested with `csmith` and I don't have any problems so far. Once we'll fix unions I will have more information. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 24 ++++ clang/lib/CIR/CodeGen/CIRGenBuilder.cpp | 71 ++++++++++ clang/lib/CIR/CodeGen/CIRGenBuilder.h | 63 +++------ clang/lib/CIR/CodeGen/CIRGenExprConst.cpp | 1 - clang/lib/CIR/CodeGen/CIRGenModule.cpp | 81 ++++++++++- clang/lib/CIR/CodeGen/CIRGenVTables.cpp | 3 +- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 6 +- clang/test/CIR/CodeGen/globals-ref-globals.c | 126 ++++++++++++++++++ clang/test/CIR/CodeGen/union-padding.c | 2 +- clang/test/CIR/CodeGen/vbase.cpp | 2 +- clang/test/CIR/CodeGen/vtable-emission.cpp | 2 +- clang/test/CIR/CodeGen/vtt.cpp | 2 +- 12 files changed, 322 insertions(+), 61 deletions(-) create mode 100644 clang/test/CIR/CodeGen/globals-ref-globals.c diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index 3e12a9307807..298d06805c54 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -622,6 +622,30 @@ def GlobalViewAttr : CIR_Attr<"GlobalView", "global_view", [TypedAttrInterface]> cir.global external @elt_ptr = #cir.global_view<@rgb, [1]> : !cir.ptr cir.global external @table_of_ptrs = #cir.const_array<[#cir.global_view<@rgb, [1]> : !cir.ptr] : !cir.array x 1>> ``` + + Note, that unlike LLVM IR's gep instruction, CIR doesn't add the leading zero index + when it's known to be constant zero, e.g. for pointers, i.e. we use indexes exactly + to access sub elements or for the offset.

These bugs were found with `csmith`. Case #1. Return value from a function. Before this PR the returned value were stored in a bit casted memory location. But for the next example it's not safe: the size of a memory slot is less than the size of return value. And the store operation cause a segfault! ``` #pragma pack(push) #pragma pack(1) typedef struct { int f0 : 18; int f1 : 31; int f2 : 5; int f3 : 29; int f4 : 24; } PackedS; #pragma pack(pop) ``` CIR type for this struct is `!ty_PackedS1_ = !cir.struct}>`, i.e. it occupies 14 bytes. Before this PR the next code ``` PackedS foo(void) { PackedS s; return s; } void check(void) { PackedS y = foo(); } ``` produced the next CIR: ``` %0 = cir.alloca !ty_PackedS1_, !cir.ptr, ["y", init] {alignment = 1 : i64} %1 = cir.call @foo() : () -> !cir.array %2 = cir.cast(bitcast, %0 : !cir.ptr), !cir.ptr> cir.store %1, %2 : !cir.array, !cir.ptr> ``` As one cat see, `%1` is an array of two 64-bit integers and the memory was allocated for 14 bytes only (size of struct). Hence the segfault! This PR fixes such cases and now we have a coercion through memory, which is even with the OG. Case #2. Passing an argument from a pointer deref. Previously for the struct types passed by value we tried to find alloca instruction in order to use it as a source for memcpy operation. But if we have pointer dereference, (in other words if we have a ` >` as alloca result) we don't need to search for the address of the location where this pointer stored - instead we're interested in the pointer itself. And it's a general approach - instead of trying to find an alloca instruction we need to find a first pointer on the way - that will be an address we meed to use for the memcpy source. I combined these two cases into a single PR since there are only few changes actually. But I can split in two if you'd prefer --- .../TargetLowering/LowerFunction.cpp | 37 +++++--- .../AArch64/aarch64-cc-structs.c | 94 +++++++++++++++++-- 2 files changed, 112 insertions(+), 19 deletions(-) diff --git a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp index 0771bce3399e..fcf95b7db7d0 100644 --- a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp +++ b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp @@ -232,6 +232,17 @@ cir::AllocaOp findAlloca(mlir::Operation *op) { return {}; } +mlir::Value findAddr(mlir::Value v) { + if (mlir::isa(v.getType())) + return v; + + auto op = v.getDefiningOp(); + if (!op || !mlir::isa(op)) + return {}; + + return findAddr(op->getOperand(0)); +} + /// Create a store to \param Dst from \param Src where the source and /// destination may have different types. /// @@ -338,10 +349,10 @@ mlir::Value createCoercedValue(mlir::Value Src, mlir::Type Ty, return CGF.buildAggregateBitcast(Src, Ty); } - if (auto alloca = findAlloca(Src.getDefiningOp())) { - auto tmpAlloca = createTmpAlloca(CGF, alloca.getLoc(), Ty); - createMemCpy(CGF, tmpAlloca, alloca, SrcSize.getFixedValue()); - return CGF.getRewriter().create(alloca.getLoc(), + if (mlir::Value addr = findAddr(Src)) { + auto tmpAlloca = createTmpAlloca(CGF, addr.getLoc(), Ty); + createMemCpy(CGF, tmpAlloca, addr, SrcSize.getFixedValue()); + return CGF.getRewriter().create(addr.getLoc(), tmpAlloca.getResult()); } @@ -371,7 +382,6 @@ mlir::Value createCoercedNonPrimitive(mlir::Value src, mlir::Type ty, auto tySize = LF.LM.getDataLayout().getTypeStoreSize(ty); createMemCpy(LF, alloca, addr, tySize.getFixedValue()); - auto newLoad = bld.create(src.getLoc(), alloca.getResult()); bld.replaceAllOpUsesWith(load, newLoad); @@ -1265,6 +1275,14 @@ mlir::Value LowerFunction::rewriteCallOp(const LowerFunctionInfo &CallInfo, // FIXME(cir): Use return value slot here. mlir::Value RetVal = callOp.getResult(); + mlir::Value dstPtr; + for (auto *user : Caller->getUsers()) { + if (auto storeOp = mlir::dyn_cast(user)) { + assert(!dstPtr && "multiple destinations for the return value"); + dstPtr = storeOp.getAddr(); + } + } + // TODO(cir): Check for volatile return values. cir_cconv_assert(!cir::MissingFeatures::volatileTypes()); @@ -1283,16 +1301,11 @@ mlir::Value LowerFunction::rewriteCallOp(const LowerFunctionInfo &CallInfo, if (mlir::dyn_cast(RetTy) && mlir::cast(RetTy).getNumElements() != 0) { RetVal = newCallOp.getResult(); + createCoercedStore(RetVal, dstPtr, false, *this); - llvm::SmallVector workList; for (auto *user : Caller->getUsers()) if (auto storeOp = mlir::dyn_cast(user)) - workList.push_back(storeOp); - for (StoreOp storeOp : workList) { - auto destPtr = - createCoercedBitcast(storeOp.getAddr(), RetVal.getType(), *this); - rewriter.replaceOpWithNewOp(storeOp, RetVal, destPtr); - } + rewriter.eraseOp(storeOp); } // NOTE(cir): No need to convert from a temp to an RValue.

2001 From: Andy Kaylor Date: Fri, 7 Feb 2025 13:15:21 -0800 Subject: [PATCH 2234/2301] [CIR] Add attribute visitor for lowering globals (#1318) This adds a new mlir-tablegen option to generate a .inc file with the complete set of attrdefs defined in a .td file and uses the file generated for CIR attrdefs to create an attr visitor. This visitor is used in the lowering of global variables directly to LLVM IR. The purpose of this change is to align the incubator lowering implementation with the recent upstream changes to make future upstreaming easier, while also fulfilling the upstream request to have the visitor be based on a tablegen created file. The new mlir-tablegen feature will be upstreamed after it is established here. No observable change is intended in the CIR code. --- .../clang/CIR/Dialect/IR/CIRAttrVisitor.h | 47 ++++++ .../clang/CIR/Dialect/IR/CMakeLists.txt | 1 + .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 156 +++++++----------- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.h | 3 +- mlir/test/mlir-tblgen/attrdefs.td | 8 + mlir/tools/mlir-tblgen/AttrOrTypeDefGen.cpp | 24 +++ 6 files changed, 141 insertions(+), 98 deletions(-) create mode 100644 clang/include/clang/CIR/Dialect/IR/CIRAttrVisitor.h diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrVisitor.h b/clang/include/clang/CIR/Dialect/IR/CIRAttrVisitor.h new file mode 100644 index 000000000000..106fb3d0ed17 --- /dev/null +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrVisitor.h @@ -0,0 +1,47 @@ +//===- CIRAttrVisitor.h - Visitor for CIR attributes ------------*- C++ -*-===// +// +// Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. +// See https://llvm.org/LICENSE.txt for license information. +// SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception +// +//===----------------------------------------------------------------------===// +// +// This file defines the CirAttrVisitor interface. +// +//===----------------------------------------------------------------------===// + +#ifndef LLVM_CLANG_CIR_DIALECT_IR_CIRATTRVISITOR_H +#define LLVM_CLANG_CIR_DIALECT_IR_CIRATTRVISITOR_H + +#include "clang/CIR/Dialect/IR/CIRAttrs.h" + +namespace cir { + +#define DISPATCH(NAME) return getImpl()->visitCir##NAME(cirAttr);

[CIR][CIRGen][TBAA] Add support for scalar types (#1329) This patch introduces support for TBAA with scalar types. By encoding the type name in the CIR, we address the limitation of distinguishing between different C++ types that map to the same CIR type.

I am very open to suggestions regarding this PR, because I'm still a bit unsure if this replicates the original codegen properly. For example, using the test added, the OG CodeGen produces: ``` entry: invoke void @_ZN1SC2Ev(ptr noundef nonnull align 1 dereferenceable(1) %s) to label %invoke.cont unwind label %lpad invoke.cont: ; preds = %entry invoke void @__cxa_rethrow() #2 to label %unreachable unwind label %lpad lpad: ; preds = %invoke.cont, %entry %0 = landingpad { ptr, i32 } catch ptr null %1 = extractvalue { ptr, i32 } %0, 0 store ptr %1, ptr %exn.slot, align 8 %2 = extractvalue { ptr, i32 } %0, 1 store i32 %2, ptr %ehselector.slot, align 4 br label %catch catch: ; preds = %lpad %exn = load ptr, ptr %exn.slot, align 8 %3 = call ptr @__cxa_begin_catch(ptr %exn) #3 %4 = load i32, ptr %r, align 4 %inc = add nsw i32 %4, 1 store i32 %inc, ptr %r, align 4 call void @__cxa_end_catch() br label %try.cont ``` and the proposed CIR equivalent produces: ``` invoke void @_ZN1SC2Ev(ptr %1) to label %5 unwind label %9 5: ; preds = %4 invoke void @__cxa_rethrow() to label %6 unwind label %13 6: ; preds = %5 br label %7 7: ; preds = %6 unreachable 8: ; No predecessors! br label %22 9: ; preds = %4 %10 = landingpad { ptr, i32 } catch ptr null %11 = extractvalue { ptr, i32 } %10, 0 %12 = extractvalue { ptr, i32 } %10, 1 br label %17 13: ; preds = %5 %14 = landingpad { ptr, i32 } catch ptr null %15 = extractvalue { ptr, i32 } %14, 0 %16 = extractvalue { ptr, i32 } %14, 1 br label %17 17: ; preds = %13, %9 %18 = phi ptr [ %11, %9 ], [ %15, %13 ] %19 = call ptr @__cxa_begin_catch(ptr %18) %20 = load i32, ptr %2, align 4 %21 = add i32 %20, 1 store i32 %21, ptr %2, align 4 call void @__cxa_end_catch() br label %22 ``` There are quite a number of differences: `phi` in the CIR version VS loading from `%exn.slot` in the OG, having multiple landing pads, etc. The CIR version still seems reasonable to me, mostly because currently we are unable to replicate the exact behavior of the OG codegen.

[This](https://github.com/llvm/clangir/blob/3e17e7b9404e1a28bf33bdd5943f4a208134d479/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp#L1169) is meant to be a `memcpy` of the alloca instead of directly passing the alloca, just like in the [OG](https://github.com/llvm/clangir/blob/3e17e7b9404e1a28bf33bdd5943f4a208134d479/clang/lib/CodeGen/CGCall.cpp#L5323). The PR was meant to use a `memcpy` and later handle cases where we don't need the `memcpy`. For example, running the following code snippet `tmp.c` using `bin/clang tmp.c -o tmp -Xclang -fclangir -Xclang -fclangir-call-conv-lowering --target=aarch64-none-linux-gnu`: ``` #include typedef struct { int a, b, c, d, e; } S; void change(S s) { s.a = 10; } void foo(void) { S s; s.a = 9; change(s); printf("%d\n", s.a); } int main(void) { foo(); return 0; } ``` gives 10 instead of 9, because we pass the pointer instead of a copy. Relevant part of the OG LLVM output: ``` @foo() %s = alloca %struct.S, align 4 %byval-temp = alloca %struct.S, align 4 %a = getelementptr inbounds nuw %struct.S, ptr %s, i32 0, i32 0 store i32 9, ptr %a, align 4 call void @llvm.memcpy.p0.p0.i64(ptr align 4 %byval-temp, ptr align 4 %s, i64 20, i1 false) call void @change(ptr noundef %byval-temp) ``` Current LLVM output through CIR: ``` @foo() %1 = alloca %struct.S, i64 1, align 4 %2 = getelementptr %struct.S, ptr %1, i32 0, i32 0 store i32 9, ptr %2, align 4 %3 = load %struct.S, ptr %1, align 4 call void @change(ptr %1) ``` So, there should be a memcpy. This PR fixes this, and adds a comment/note for the future cases where we need to check if the copy is not needed. I have also updated the old test with structs having size > 128. --- .../TargetLowering/LowerFunction.cpp | 8 ++++++- .../AArch64/aarch64-cc-structs.c | 24 +++++++++++-------- 2 files changed, 21 insertions(+), 11 deletions(-) diff --git a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp index fcf95b7db7d0..023e3baf2105 100644 --- a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp +++ b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp @@ -1166,7 +1166,13 @@ mlir::Value LowerFunction::rewriteCallOp(const LowerFunctionInfo &CallInfo, if (::cir::MissingFeatures::undef()) cir_cconv_unreachable("NYI"); - IRCallArgs[FirstIRArg] = alloca; + // TODO(cir): add check for cases where we don't need the memcpy + auto tmpAlloca = createTmpAlloca( + *this, alloca.getLoc(), + mlir::cast(alloca.getType()).getPointee()); + auto tySize = LM.getDataLayout().getTypeAllocSize(I->getType()); + createMemCpy(*this, tmpAlloca, alloca, tySize.getFixedValue()); + IRCallArgs[FirstIRArg] = tmpAlloca; // NOTE(cir): Skipping Emissions, lifetime markers. diff --git a/clang/test/CIR/CallConvLowering/AArch64/aarch64-cc-structs.c b/clang/test/CIR/CallConvLowering/AArch64/aarch64-cc-structs.c index b434edc09dfe..95217199ed52 100644 --- a/clang/test/CIR/CallConvLowering/AArch64/aarch64-cc-structs.c +++ b/clang/test/CIR/CallConvLowering/AArch64/aarch64-cc-structs.c @@ -171,20 +171,24 @@ GT_128 get_gt_128(GT_128 s) { } // CHECK: cir.func no_proto @call_and_get_gt_128(%arg0: !cir.ptr -// CHECK: %[[#V0:]] = cir.alloca !ty_GT_128_, !cir.ptr, {{.*}} {alignment = 8 : i64} -// CHECK: %[[#V1:]] = cir.alloca !ty_GT_128_, !cir.ptr, {{.*}} {alignment = 8 : i64} -// CHECK: cir.call @get_gt_128(%[[#V1]], %arg0) : (!cir.ptr, !cir.ptr) -> () -// CHECK: %[[#V2:]] = cir.load %[[#V1]] : !cir.ptr, !ty_GT_128_ -// CHECK: cir.store %[[#V2]], %[[#V0]] : !ty_GT_128_, !cir.ptr +// CHECK: %[[#V0:]] = cir.alloca !ty_GT_128_, !cir.ptr, ["tmp"] {alignment = 8 : i64} +// CHECK: %[[#V1:]] = cir.load %arg0 : !cir.ptr, !ty_GT_128_ +// CHECK: %[[#V2:]] = cir.alloca !ty_GT_128_, !cir.ptr, [""] {alignment = 8 : i64} +// CHECK: %[[#V3:]] = cir.alloca !ty_GT_128_, !cir.ptr, ["tmp"] {alignment = 8 : i64} +// CHECK: %[[#V4:]] = cir.cast(bitcast, %arg0 : !cir.ptr), !cir.ptr +// CHECK: %[[#V5:]] = cir.cast(bitcast, %[[#V3]] : !cir.ptr), !cir.ptr +// CHECK: %[[#V6:]] = cir.const #cir.int<24> : !u64i +// CHECK: cir.libc.memcpy %[[#V6]] bytes from %[[#V4]] to %[[#V5]] : !u64i, !cir.ptr -> !cir.ptr +// CHECK: cir.call @get_gt_128(%[[#V2]], %[[#V3]]) : (!cir.ptr, !cir.ptr) -> () // CHECK: cir.return // LLVM: void @call_and_get_gt_128(ptr %[[#V0:]]) // LLVM: %[[#V2:]] = alloca %struct.GT_128, i64 1, align 8 -// LLVM: %[[#V3:]] = alloca %struct.GT_128, i64 1, align 8 -// LLVM: call void @get_gt_128(ptr %[[#V3]], ptr %[[#V0]]) -// LLVM: %[[#V4:]] = load %struct.GT_128, ptr %[[#V3]], align 8 -// LLVM: store %struct.GT_128 %[[#V4]], ptr %[[#V2]], align 8 -// LLVM: ret void +// LLVM: %[[#V3:]] = load %struct.GT_128, ptr %[[#V0]], align 8 +// LLVM: %[[#V4:]] = alloca %struct.GT_128, i64 1, align 8 +// LLVM: %[[#V5:]] = alloca %struct.GT_128, i64 1, align 8 +// LLVM: call void @llvm.memcpy.p0.p0.i64(ptr %[[#V5]], ptr %[[#V0]], i64 24, i1 false) +// LLVM: call void @get_gt_128(ptr %[[#V4]], ptr %[[#V5]]) GT_128 call_and_get_gt_128() { GT_128 s; s = get_gt_128(s); From 090718c785c7e4a22f53b655aeb2755a6e1da471 Mon Sep 17 00:00:00 2001 From: Robert Konicar Date: Wed, 12 Feb 2025 15:00:28 +0100 Subject: [PATCH 2252/2301] [CIR] Fix error messages when the conversion to MLIR standard dialects fails.

For those constant allocas in non-loop inner scopes, this PR keeps their constant flags during alloca hoisting. LLVM lowering would correctly emit necessary invariant metadata for those allocas. For those constant allocas in a loop, this PR introduces a new operation `cir.invariant_group` that marks the beginning of the lifetime of the constant objects. This operation is put at the location of the alloca operation before hoisting them. This PR updates LLVM lowering to emit the necessary invariant metadata when loading and storing through such pointers. This PR takes care of the special case where the constant alloca represents a variable declared in the condition part of a while loop. In such a case, this PR removes the constant flag on the alloca operation when hositing them. --- clang/include/clang/CIR/Dialect/IR/CIROps.td | 57 ++++++ .../CIR/Dialect/Transforms/HoistAllocas.cpp | 165 ++++++++++++++++-- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 42 +++-- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.h | 15 ++ clang/test/CIR/CodeGen/const-alloca.cpp | 85 +++++++++ 5 files changed, 341 insertions(+), 23 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index a08e16df9222..b06c61577150 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -3563,6 +3563,63 @@ def LLVMIntrinsicCallOp : CIR_Op<"llvm.intrinsic"> { } +//===----------------------------------------------------------------------===// +// InvariantGroupOp +//===----------------------------------------------------------------------===// + +def InvariantGroupOp + : CIR_Op<"invariant_group", [Pure, SameOperandsAndResultType]> { + let summary = "Start an invariant group"; + let description = [{ + The `cir.invariant_group` operation takes a single pointer value as argument + and returns the same pointer value with fresh [invariant group] information. + All loads and stores that access the returned pointer value are presumed by + the optimizer to load or store the same value. + + [invariant group]: https://llvm.org/docs/LangRef.html#invariant-group-metadata + + This operation is not emitted during CIRGen.

It's similar to `local` variables in OpenCL which all threads in a work-group can access. Hence they are realized as `static` variables in addrspace(local). On the other hand, the local variables inside a kernel (without special attributes) are just regular variables, typically emitted by `CreateTempAlloca`. They are in the default address space.

So, the last PR did not support statements that come after the `UnreachableOp` from the `rethrow`, we just ignored them, e.g: ``` struct S { S() {} }; void foo() { int r = 1; try { throw; S s; } catch (...) { ++r; } } ``` This PR fixes this. A few changes: - `rethrow` statements split their block into multiple blocks. - Tests with statements that come after the `rethrow` were added and old ones were modified. Concern: - The `ScopeOp` workaround still exists which I guess was one of the main concerns when we tried in the last PR.

If we manage `cir::TBAAStructAttr` by adding a new method to `ASTRecordDeclInterface`, it will also introduce duplication between `CIRGen` and LLVM lowering. --- .../clang/CIR/Dialect/IR/CIRTBAAAttrs.td | 75 ++++- clang/lib/CIR/CodeGen/CIRGenTBAA.cpp | 97 ++++++- clang/lib/CIR/CodeGen/CIRGenTBAA.h | 4 + clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 2 +- clang/test/CIR/CodeGen/tbaa-struct.cpp | 262 ++++++++++++++++++ 5 files changed, 436 insertions(+), 4 deletions(-) create mode 100644 clang/test/CIR/CodeGen/tbaa-struct.cpp diff --git a/clang/include/clang/CIR/Dialect/IR/CIRTBAAAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRTBAAAttrs.td index 40e2d2d7f1d9..83d3d24c05c8 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRTBAAAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRTBAAAttrs.td @@ -50,9 +50,82 @@ def CIR_TBAATagAttr : CIR_Attr<"TBAATag", "tbaa_tag", [], "TBAAAttr"> { let assemblyFormat = "`<` struct(params) `>`"; } +def CIR_TBAAMemberAttr : CIR_Attr<"TBAAMember", "tbaa_member", []> { + let summary = "Attribute representing a member of a TBAA structured type."; + let parameters = (ins "TBAAAttr":$type_desc, + "int64_t":$offset); + let description = [{ + Define a TBAA struct attribute. + + Example: + ```mlir + !ty_StructS = !cir.struct + #tbaa_scalar = #cir.tbaa_scalar + #tbaa_scalar1 = #cir.tbaa_scalar + #tbaa_struct = #cir.tbaa_struct, <#tbaa_scalar, 4>}> + ``` + + See the following link for more details: + https://llvm.org/docs/LangRef.html#tbaa-metadata + }]; + + let assemblyFormat = "`<` params `>`"; +} + +def CIR_TBAAMemberAttrArray : ArrayRefParameter<"TBAAMemberAttr"> { + let summary = "Array of TBAAMemberAttr attributes."; + let printer = [{ + $_printer << '{'; + llvm::interleaveComma($_self, $_printer, [&](TBAAMemberAttr attr) { + $_printer.printStrippedAttrOrType(attr); + }); + $_printer << '}'; + }]; + let parser = [{ + [&]() -> llvm::FailureOr> { + using Result = llvm::SmallVector; + if ($_parser.parseLBrace()) + return mlir::failure(); + llvm::FailureOr result = mlir::FieldParser::parse($_parser); + if (failed(result)) + return mlir::failure(); + if ($_parser.parseRBrace()) + return mlir::failure(); + return result; + }() + }]; +} + +def CIR_TBAAStructAttr : CIR_Attr<"TBAAStruct", + "tbaa_struct", [], "TBAAAttr"> { + let summary = "Describes a struct type in TBAA"; + + let parameters = (ins StringRefParameter<> : $id, + CIR_TBAAMemberAttrArray:$members); + + let description = [{ + Define a TBAA struct attribute. + + Example: + ```mlir + !ty_StructS = !cir.struct + #tbaa_scalar = #cir.tbaa_scalar + #tbaa_scalar1 = #cir.tbaa_scalar + // CIR_TBAAStructAttr + #tbaa_struct = #cir.tbaa_struct, <#tbaa_scalar, 4>}> + ``` + + See the following link for more details: + https://llvm.org/docs/LangRef.html#tbaa-metadata + }]; + + let assemblyFormat = "`<` struct(params) `>`"; +} + def CIR_AnyTBAAAttr : AnyAttrOf<[ CIR_TBAAAttr, CIR_TBAAOmnipotentChar, - CIR_TBAAScalarAttr, + CIR_TBAAScalarAttr, + CIR_TBAAStructAttr, CIR_TBAATagAttr ]>; diff --git a/clang/lib/CIR/CodeGen/CIRGenTBAA.cpp b/clang/lib/CIR/CodeGen/CIRGenTBAA.cpp index fa8325c654cb..f2d46a30cc53 100644 --- a/clang/lib/CIR/CodeGen/CIRGenTBAA.cpp +++ b/clang/lib/CIR/CodeGen/CIRGenTBAA.cpp @@ -1,4 +1,5 @@ #include "CIRGenTBAA.h" +#include "CIRGenCXXABI.h" #include "CIRGenTypes.h" #include "mlir/IR/BuiltinAttributes.h" #include "mlir/IR/MLIRContext.h" @@ -204,7 +205,7 @@ cir::TBAAAttr CIRGenTBAA::getTypeInfo(clang::QualType qty) { // function. if (isValidBaseType(qty)) { assert(!cir::MissingFeatures::tbaaTagForStruct()); - return tbaa_NYI(mlirContext); + return getValidBaseTypeInfo(qty); } const clang::Type *ty = astContext.getCanonicalType(qty).getTypePtr(); @@ -248,9 +249,101 @@ mlir::ArrayAttr CIRGenTBAA::getTBAAStructInfo(clang::QualType qty) { } cir::TBAAAttr CIRGenTBAA::getBaseTypeInfo(clang::QualType qty) { - return tbaa_NYI(mlirContext); + return isValidBaseType(qty) ?

In the traditional codegen the pointer has no type, so it was sufficient for the Address class to simply track the type it was supposed to be pointing to. Since ClangIR pointer values are typed, the Address::withType function wasn't really doing what it was supposed to. It returned an object with the same pointer that the original object had, but with a mismatched element type. This change updates the Address::withType function to perform a bitcast to get the expected pointer type before creating a new Address object. It also adds assertions in the Address class to verify that pointer type and element type are consistent and updates many places that were causing those assertions to fire. These code changes cause extra bitcasts to be emitted in a few places. Regression tests have been updated as needed to reflect the CIR that is now generated. --- clang/lib/CIR/CodeGen/Address.h | 24 ++++++++++++------- clang/lib/CIR/CodeGen/CIRAsm.cpp | 10 ++++---- clang/lib/CIR/CodeGen/CIRGenAtomic.cpp | 13 ++++++---- clang/lib/CIR/CodeGen/CIRGenBuilder.cpp | 14 ++++++++++- clang/lib/CIR/CodeGen/CIRGenBuilder.h | 4 ++-- .../lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenCXX.cpp | 3 +-- clang/lib/CIR/CodeGen/CIRGenClass.cpp | 4 ++-- clang/lib/CIR/CodeGen/CIRGenDecl.cpp | 9 +++---- clang/lib/CIR/CodeGen/CIRGenException.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenExpr.cpp | 2 +- clang/lib/CIR/CodeGen/CIRGenExprAgg.cpp | 3 ++- clang/lib/CIR/CodeGen/CIRGenExprCXX.cpp | 14 ++++++----- clang/lib/CIR/CodeGen/CIRGenExprScalar.cpp | 4 ++-- clang/lib/CIR/CodeGen/CIRGenItaniumCXXABI.cpp | 16 +++++++++---- clang/test/CIR/CodeGen/atomic-thread-fence.c | 10 ++++---- clang/test/CIR/CodeGen/atomic-xchg-field.c | 5 ++-- clang/test/CIR/CodeGen/atomic.cpp | 6 ++--- clang/test/CIR/CodeGen/union-init.c | 6 ++--- 19 files changed, 91 insertions(+), 60 deletions(-) diff --git a/clang/lib/CIR/CodeGen/Address.h b/clang/lib/CIR/CodeGen/Address.h index b88bd4378647..5f82dd6b7eff 100644 --- a/clang/lib/CIR/CodeGen/Address.h +++ b/clang/lib/CIR/CodeGen/Address.h @@ -25,6 +25,9 @@ namespace clang::CIRGen { +// Forward declaration to avoid a circular dependency +class CIRGenBuilderTy;

CUDA compilation works as follows (irrelevant arguments omitted): ```sh # First compile for device, generating PTX assembly clang++ test.cu -fcuda-is-device -o device.s # Convert that into a binary file ptxas device.s --output-file device.o fatbin --create device.fatbin --image=profile=sm_52,file=device.o # Pass that file as an argument to host clang++ test.cu -fcuda-include-gpubinary device.fatbin -cuid="some unique id" ``` And from the name of GPU binary, we can obtain a handle for registration. So we add an attribute to ModuleOp, recording that name. If that `-fcuda-include-gpubinary` is not specified (like in the test `simple.cu`), OG will not generate any registration function. We do the same here by not generating the attribute. --- .../clang/CIR/Dialect/IR/CIRCUDAAttrs.td | 19 ++++++++++++++++++- .../clang/CIR/Dialect/IR/CIRDialect.td | 1 + clang/lib/CIR/CodeGen/CIRGenCUDARuntime.cpp | 2 -- clang/lib/CIR/CodeGen/CIRGenModule.cpp | 11 +++++++++++ clang/test/CIR/CodeGen/CUDA/registration.cu | 9 +++++++++ clang/test/CIR/CodeGen/CUDA/simple.cu | 2 +- clang/test/CIR/CodeGen/HIP/simple.cpp | 2 +- 7 files changed, 41 insertions(+), 5 deletions(-) create mode 100644 clang/test/CIR/CodeGen/CUDA/registration.cu diff --git a/clang/include/clang/CIR/Dialect/IR/CIRCUDAAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRCUDAAttrs.td index fd74fe2d349e..e658bb49e815 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRCUDAAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRCUDAAttrs.td @@ -18,7 +18,7 @@ //===----------------------------------------------------------------------===// def CUDAKernelNameAttr : CIR_Attr<"CUDAKernelName", - "cuda_kernel_name"> { + "cu.kernel_name"> { let summary = "Device-side function name for this stub."; let description = [{ @@ -35,4 +35,21 @@ def CUDAKernelNameAttr : CIR_Attr<"CUDAKernelName", let assemblyFormat = "`<` $kernel_name `>`"; } +def CUDABinaryHandleAttr : CIR_Attr<"CUDABinaryHandle", + "cu.binary_handle"> { + let summary = "Fat binary handle for device code."; + let description = + [{ + This attribute is attached to the ModuleOp and records the binary file + name passed to host. + + CUDA first compiles device-side code into a fat binary file.

The lowering is ABI-specific and this patch only considers Itanium ABI. Itanium ABI lowers pointers to member functions to a struct with two fields of type `ptrdiff_t`. To extract fields from such aggregate values, this PR includes a new operation `cir.extract_member` to accomplish this. --- .../include/clang/CIR/Dialect/IR/CIRAttrs.td | 10 + clang/include/clang/CIR/Dialect/IR/CIROps.td | 58 ++++ clang/include/clang/CIR/MissingFeatures.h | 3 + clang/lib/CIR/Dialect/IR/CIRDialect.cpp | 16 + .../Transforms/TargetLowering/CIRCXXABI.h | 20 ++ .../TargetLowering/ItaniumCXXABI.cpp | 296 +++++++++++++++++- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp | 62 +++- .../CIR/Lowering/DirectToLLVM/LowerToLLVM.h | 25 ++ .../CIR/CodeGen/pointer-to-member-func.cpp | 38 +++ clang/test/CIR/Lowering/struct.cir | 15 + 10 files changed, 530 insertions(+), 13 deletions(-) diff --git a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td index d3f5c88df19c..fa7b5c0d7a08 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td +++ b/clang/include/clang/CIR/Dialect/IR/CIRAttrs.td @@ -573,6 +573,16 @@ def MethodAttr : CIR_Attr<"Method", "method", [TypedAttrInterface]> { let hasCustomAssemblyFormat = 1; let genVerifyDecl = 1; + + let extraClassDeclaration = [{ + bool isNull() const { + return !getSymbol().has_value() && !getVtableOffset().has_value(); + } + + bool isVirtual() const { + return getVtableOffset().has_value(); + } + }]; } //===----------------------------------------------------------------------===// diff --git a/clang/include/clang/CIR/Dialect/IR/CIROps.td b/clang/include/clang/CIR/Dialect/IR/CIROps.td index b06c61577150..1feb631bfcdf 100644 --- a/clang/include/clang/CIR/Dialect/IR/CIROps.td +++ b/clang/include/clang/CIR/Dialect/IR/CIROps.td @@ -2850,6 +2850,64 @@ def GetMemberOp : CIR_Op<"get_member"> { let hasVerifier = 1; } +//===----------------------------------------------------------------------===// +// ExtractMemberOp +//===----------------------------------------------------------------------===// + +def ExtractMemberOp : CIR_Op<"extract_member", [Pure]> { + let summary = "Extract the value of a member of a struct value"; + let description = [{ + The `cir.extract_member` operation extracts the value of a particular member + from the input record.

Suppose we have a simple struct like this. ```cpp struct dim3 { int x, y, z; }; ``` It can be coerced into ```cpp struct dim3_ { uint64_t xy; int z; }; ``` And for a function that receives it as an argument, OG does the following transformation for x86: ```cpp void f(dim3 arg) { /* Before */ } void f(uint64_t xy, int z) { /* After */ } ``` Now this transformation is implemented in the CallConvLowering pass of CIR. --- clang/include/clang/CIR/MissingFeatures.h | 1 + .../TargetLowering/LowerFunction.cpp | 44 +++++++++- .../Transforms/TargetLowering/Targets/X86.cpp | 12 ++- .../CIR/CallConvLowering/x86_64/basic.cpp | 82 ++++++++++++++++++- 4 files changed, 134 insertions(+), 5 deletions(-) diff --git a/clang/include/clang/CIR/MissingFeatures.h b/clang/include/clang/CIR/MissingFeatures.h index 67547c376790..21bfe021dd1a 100644 --- a/clang/include/clang/CIR/MissingFeatures.h +++ b/clang/include/clang/CIR/MissingFeatures.h @@ -347,6 +347,7 @@ struct MissingFeatures { static bool undef() { return false; } static bool noFPClass() { return false; } static bool llvmIntrinsicElementTypeSupport() { return false; } + static bool argHasMaybeUndefAttr() { return false; } //-- Missing parts of the CIRGenModule::Release skeleton. static bool emitModuleInitializers() { return false; } diff --git a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp index 023e3baf2105..59420c1d2b54 100644 --- a/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp +++ b/clang/lib/CIR/Dialect/Transforms/TargetLowering/LowerFunction.cpp @@ -612,7 +612,7 @@ llvm::LogicalResult LowerFunction::buildFunctionProlog( Ptr.getLoc(), PointerType::get(STy, ptrType.getAddrSpace()), CastKind::bitcast, Ptr); } else { - cir_cconv_unreachable("NYI"); + addrToStoreInto = createTmpAlloca(*this, Ptr.getLoc(), STy); } assert(STy.getNumElements() == NumIRArgs); @@ -628,7 +628,7 @@ llvm::LogicalResult LowerFunction::buildFunctionProlog( } if (srcSize > dstSize) { - cir_cconv_unreachable("NYI"); + createMemCpy(*this, Ptr, addrToStoreInto, dstSize); } } } else { @@ -1126,9 +1126,47 @@ mlir::Value LowerFunction::rewriteCallOp(const LowerFunctionInfo &CallInfo, // Fast-isel and the optimizer generally like scalar values better than // FCAs, so we flatten them if this is safe to do for this argument. + // As an example, if we have SrcTy = struct { i32, i32, i32 }, then the + // coerced type can be STy = struct { u64, i32 }.

Change all the tests to use or to expect the new format for function types. The contents and the semantics of `cir::FuncType` are unchanged. Only the assembly format is being changed. Functions that return `void` in C or C++ are still represented in MLIR as having no return type. Most of the changes are in `parseFuncType` and `printFuncType` and the functions they call in `CIRTypes.cpp`. A `FuncType::verify` function was added to check that an explicit return type is not `cir::VoidType`. `FuncType::isVoid()` was renamed to `FuncType::hasVoidReturn()` Some comments for `FuncType` were improved. An `llvm_unreachable` was added to `StructType::getKindAsStr` to suppress a compiler warning and to catch a memory error that corrupts the `RecordKind` field.
