Because there is often some confusion, note that there are two different projects in this space with different approaches.<p>The project discussed in the video above is a new front end to GCC (written in C++, as is typical for GCC frontends) and is developed here: <a href="https://github.com/Rust-GCC/gccrs" rel="nofollow">https://github.com/Rust-GCC/gccrs</a><p>The other project involves plugging GCC's backend into the existing rustc frontend, and is developed here: <a href="https://github.com/rust-lang/rustc_codegen_gcc" rel="nofollow">https://github.com/rust-lang/rustc_codegen_gcc</a><p>Both projects intend to eventually allow Rust code to make use of GCC. But they will likely appeal to different sets of users: the former project appeals to people invested in the GCC ecosystem who want to use Rust without installing a whole separate toolchain, and the latter to people invested in the Rust ecosystem who want to benefit from GCC's broader target support.
