I'm not aware of the official GCC roadmap but LWN covered it in "predictions for the new year" article [1]. Quoting: "The gccrs project will deliver a working Rust compiler this year; it will be usable to build the kernel's Rust code. This ambitious project ... The availability of a GCC-based compiler will make that transition easier for many people, especially those working with architectures that the LLVM-based rustc compiler does not support..."
