Right but that just means it's LLVM being clever, not rustc. The main compiler is the self-hosting gc go compiler. Iirc ~~it's the reference implementation~~ erm I guess it's determined by spec, not reference implemenation. Gc is definitely "the default" though. Then There's the gofrontend, which is a compiler frontend to other compilers, which can work with gcc and llvm. I am not aware of the state of the art for these, but I wonder if there are performance differences.
