Even though that is very welcome news, gcc-15 now Build-Depends on cargo -> rustc -> llvm. I do not see how rustc_codegen_gcc is going to resolve this dependency chain. I also do not see us wanting to break it. Realistically, we cannot keep all pieces that transitively depend on llvm out of essential forever. At some point, llvm will need to be fixed. llvm support practically is a requirement for full ports already. It will be a hard requirement before too long. The Python JIT now also relies on llvm.
