Yet Another Compiler

A pseudolanguage compiler;

FUNCTION fibo(i)
BEGIN
    IF i <= 1 THEN
        RETURN i;
    ELSE
        RETURN fibo(i - 2) + fibo(i - 1);
    EIF
END

FUNCTION main()
BEGIN
    READ n;
    RETURN fibo(n);
END

See compiler/LISEZMOI.md (french) for the language reference.

Backends

Two backends are available:

• Random-access machine (see rame/README.md)
• LLVM (work in progress)

File structure

• compiler/: lexing, parsing, AST (Flex, Yacc, C)
• compiler/ram/: RA-machine backend (C)
• compiler/llvm/: LLVM backend (C++)
• rame/: RA-machine emulator and optimizer library (Rust)
• driver/: executables (Rust)

Usage

Requires Clang & GNU Make.

Without Rust

Just run make in compiler/.

./arc infile [-o outfile]

With Rust

Available binaries: rame-cc, rame-opt, rame-run, rame-test.

Usage: rame-run [OPTIONS] <infile> [args]...

Arguments:
  <infile>   The program to run
  [args]...  The program's arguments

Options:
  -b, --bits <BITS>  The integer's type bits [default: 16] [possible values: 8, 16, 32, 64, 128]
  -O                 Optimize the RAM program before running it
  -c                 Compile the algorithmic program as a first step
  -h, --help         Print help
  -V, --version      Print version

Example

’Tis but a reminder for meowself, as the LLVM backend is still a WIP.

FONCTION main()
DÉBUT
    AFFICHER 1 + 2;
FIN

$ cargo run --bin rame-cc -- ./add.algo -o add.out
$ clang add.out compiler/src/llvm/intrinsics.c
