We’ve got a few bugs fixed that allowed us to fully bootstrap the Rust compiler with rustc_codegen_gcc and to fix the CI for Rust for Linux compiled with rustc_codegen_gcc. We hope to improve our testing within the Rust repo in order to allow us to move faster towards our goals.
That’s still a very major achievement! Do I understand correctly this means all target architectures supported by GCC are now unlocked for Rust too?
Well, we can generate code for targets not supported by LLVM, but it is not trivial to setup (we hope to get rustup support in the coming months to make this easier) and most GCC targets won’t pass as many tests as x86-64 with rustc_codegen_gcc. There’s some info in the wiki about some targets that people tried.
It is an optional goal for the Google Summer of Code to bootstrap the rust compiler on other platforms, so we might be able to get a working
rustcfor new platforms by the end of the summer.
