What's wrong with the compiler Rust already has

[–] jokeyrhyme@lemmy.ml 4 points 2 years ago (2 children)

LLVM supports fewer target machines than GCC

https://gcc.gnu.org/backends.html has a big table

It's also good to have multiple compilers to exercise the spec.

Holy cow

From what understand GCC supports more architectures than LLVM.

Also having alternatives is always nice.
