Rust is coming to GCC
(www.phoronix.com)
What's wrong with the compiler Rust already has
LLVM supports fewer target machines than GCC
https://gcc.gnu.org/backends.html has a big table

An easily retargettable code generator, which currently supports X86, X86-64, PowerPC, PowerPC-64, ARM, Thumb, SPARC, Alpha, CellSPU, MIPS, MSP430, SystemZ, WebAssembly and XCore.
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.

I feel like Hank Hill needs to step in and say "You're not making a good compiler, you're just making Rust bad."
