This was recently fixed upstream in LLVM, so we update our default layout to match. @rustbot label: +llvm-main
This way using pidfd_spawnp won't have to rely on procfs, avoiding an unpleasant edge-case
where the child is spawned but we can't get the pid.
And `pidfd.{try_}wait` will be able to return the exit status even after a process has been reaped.
At least on newer kernels.
`lower_anon_const_to_const_arg_direct` to `lower_anon_const_to_const_arg_and_alloc` and `lower_anon_const_to_const_arg`
…rait, r=jdonszelmann Impls and impl items inherit `dead_code` lint level of the corresponding traits and trait items https://github.com/rust-lang/rust/blob/master/compiler/rustc_passes/src/dead.rs#L360-L361 won't insert assoc items into the live set, so that impl items cannot be marked live. This PR lets impls and impl items can inherit lint levels of the corresponding traits and trait items. Fixes rust-lang#144060 r? ```@petrochenkov```
…ern, r=Amanieu naked functions: emit `.private_extern` on macos fixes rust-lang#148307 Emit `.private_extern` on macos when the naked function uses `Linkage::Internal`. Failing to do so can cause issues with LTO. The documentation on this directive is kind of sparse, but I believe this is at least not incorrect, and does fix the issue. r? `@Amanieu` cc `@bjorn3`
…nikic rustc_codegen_llvm: update alignment for double on AIX This was recently fixed upstream in LLVM, so we update our default layout to match. ```@rustbot``` label: +llvm-main
Refactor function names of `rustc_ast_lowering` close: rust-lang#150062 I'll rebase after rust-lang#149114 is merged. Would it be better to change `lower_const_path_to_const_arg` → `lower_const_path_to_const_arg_and_intern`, `lower_array_length_to_const_arg` → `lower_array_length_to_const_arg_and_intern`? r? `@lcnr`
use PIDFD_GET_INFO ioctl when available

THIR pattern building: Move all `thir::Pat` creation into `rustc_mir_build::thir::pattern` The code in `thir::cx::block` was the only code outside of `thir::pattern` that created `thir::Pat` nodes. Moving it makes the signature of `pat_from_hir` a bit messier, but ensures that all `thir::Pat` creation occurs in one module. That will be useful when trying to change `thir::Pat`, e.g. by adding fields to remove the need for wrapper nodes. There should be no change to compiler output.
MGCA: pretty printing for struct expressions and tuple calls
not sure
1. if there any tests that i need to adjust
2. if i should add any test for it
3. if humanity has come up with anything better than checking if that's first iteration or not with flag when printing sequences with separator
in case there is no tests for it and i dont have to add any, there is a demonstration of this ✨ pretty ✨ printing (this is output from `-Z unpretty=hir`)
```
fn test_errors<const N:
usize>() {
// accepts_enum::<{ None::<u32> }>();
accepts_point::<Point1 { a: N, b: N }>();
accepts_point::<Point(N, N)>();
}
```
btw it does not print const block
for this
```
accepts_point::<{ Point1 { a: const {N + 1}, b: N } }>();
```
it will print
```
accepts_point::<Point1 { a: { N + 1 }, b: N }>();
```
not sure if we want to print const blocks or not

Improve comment clarity in candidate_may_shadow I think this should be the right correction, but I'm not sure.
…-ld, r=Mark-Simulacrum Update wasm-component-ld Same as rust-lang#147495, just keeping it up-to-date.
…ce, r=BoxyUwU Fix ICE when transmute Assume field is invalid This PR fixes an internal compiler error in `rustc_transmute` where initializing an `Assume` field (like `alignment`) with a non-scalar constant (like a struct) caused a panic. The fix updates `from_const` to use `try_to_scalar()` instead of assuming the value is always a leaf. It now gracefully returns `None` for invalid types, allowing the compiler to report standard "missing field initialiser" errors instead of crashing. Fixes rust-lang#150506
Enable merge queue in new bors We can proactively merge this now. Note that new bors will still default to being "paused" and not running the merge queue, after being restarted: - https://github.com/rust-lang/bors/blob/e1fafaa3b89c225069fa2aa1193096e1d66075c3/src/bors/merge_queue.rs#L101 - https://github.com/rust-lang/bors/blob/bf491ee40d1fc877af273f2ec92a2968dee8cdb7/src/github/api/mod.rs#L159 - rust-lang#112049 (comment) We can resume it quickly with a command, to test how the merging functionality behaves.
