I was gonna say. Or a maintainer, for that matter.

How much is left to implement to reach feature parity with Rustc?

They include a table towards the bottom for the monthly reports. The latest is at https://rust-gcc.github.io/2024/01/1...ly-report.html

A lot. This whole effort is kinda pointless considering that rustc using the GCC codegen backend can already compile all the rust kernel code, and this GCC frontend is never going to be able to keep up with the much faster rustc release cadence and nightly builds. GCC organizationally just isn't capable of it.

rustc_codegen_gcc is not even free software so gccrs wins by default.

In this current form, never. gccrs devs already expressed that they want to do further development in Rust after ending this one as a new step in GCC's bootstrap process.

Maybe for your use case. rustc using the GCC libgccjit codegen doesn't work cross-compiling to SuperH except with 3rd party patches that haven't worked in months.
But GCCRS works out of the box. Of course GCCRS is way behind in features, it's still super early on for it unfortunately.

How so?
