Note that there is a separate project to use the GCC backend with the Rustc frontend. At least in the short-term, that project will be the better approach to providing the benefits of more hardware support, since it will be more complete and compatible with the rustc/llvm compiler. The main benefit of a GCC front-end is to move Rust beyond a single vendor, and shakeout ambiguities in the (informal) language specification.
