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.
