Rust For Linux 7.3 Begins Seeing Fixes To Prepare For Rust's GCC Backend

>The motivation of the development is using GCC code generation by rustc for architectures not supported by LLVM but are supported by GCC. There are a number of CPU architectures supported by the Linux kernel and GCC but not supported by LLVM like m68k, Alpha, and other embedded/micro-controller ISAs… This also allows employing GCC’s compiler optimizations. The latest rustc_codegen_gcc code can be found via rustc_codegen_gcc on GitHub. This isn’t to be confused with gccrs as the GCC front-end for Rust
