Makes it easier to target embedded arches. For example, LLVM doesn't target the MSP430 from TI, but there is a gcc fork for it. Sure, you can write a new backen

Makes it easier to target embedded arches. For example, LLVM doesn't target the MSP430 from TI, but there is a gcc fork for it. Sure, you can write a new backend for LLVM, but that's a whole different ballgame. This way it would be Rust -> LLVM IR -> C -> GCC for MSP430.
