For this, gcc-rs[1][2] is the most promising candidate.

- Narishma 3mo agoBut what about platforms that even GCC doesn't support well? I'm thinking mostly retro stuff like 16-bit x86.
- moltonel 3mo agoGccrs is valuable for various reasons (bootstrapping, refining the spec, etc), but for the main purpose of "compiling to targets supported by gcc but not llvm", it's definitely not as promising as https://github.com/rust-lang/rustc_codegen_gcc https://github.com/rust-lang/rustc_codegen_gcc. It's a rustc backend, at the same level as llvm or cranelift, it's much further along than gccrs (already available as a rustup component and can compile any rust code) and will not suffer from lagging behind rustc. But OP has wider ambitions: the real niche targets are supported by neither gcc nor llvm. A rust-to-c transpiler that can adapt to weird C compilers should have a very wide reach.
