LLVM. The race between most used compilers is in producing fastest code. There are only few folk who care about correctness and compile times. LLVM, while its drawbacks are not highlighted, is a monolith and only slightly better than GCC in some areas. Compile times being one of them. Not to forget "fast" compilers don't apply many optimizations. There are some rust specific reasons too, like lack of binary dependencies.
