It is different, and is a great project. At the end of the day, with that strategy, you still end up with two compilers, not one single compiler, and some folks are attached to "we use this single compiler to build our entire base system." You also have to then continue the bootstrap chain to get up to current rustc, and I think folks hope that this project will track upstream more closely. I also don't think that because it compiles to C it automatically supports all of the platforms gcc does, but I haven't personally investigated that because I don't have any of that exotic hardware. EDIT: oh yeah and the project itself describes this stuff here https://github.com/Rust-GCC/gccrs/wiki/Frequently-Asked-Ques...

I agree with the hidden cost of PR labor for volunteer-run projects. But a summary of the project can be very short and efficient. Copied (shortened) from the README: > gccrs is a full alternative implementation of the Rust language ontop of GCC with the goal to become fully upstream with the GNU toolchain. Please find the answers to frequently asked questions over on: https://github.com/Rust-GCC/gccrs/wiki/Frequently-Asked-Ques... Two sentences like these would be more than enough to give a person passing by enough information to know what it's about, if it'd be useful for them, and whether they'd like to keep on reading.

I wish the blog post opened with a sentence or two for context. This is a snip from the readme [1] on GitHub: > Please note, the compiler is in a very early stage and not usable yet for compiling real Rust programs. > gccrs is a full alternative implementation of the Rust language ontop of GCC with the goal to become fully upstream with the GNU toolchain. I'm happy that there's work on alternative Rust compilers though! [1] https://github.com/Rust-GCC/gccrs

I was wondering the same thing. It's not as though LLVM is some niche project that only Rust is using; it's the backend for a large number of compilers, and I imagine this will continue to be the case moving forward. There are now even languages that are written in languages that use LLVM for their backend, like gleam [1]. I think, ideally, there would be a concerted effort to extend LLVM compatibility to those platforms. But I don't think it's unreasonable to assume that there simply won't be--I sometimes run into problems on aarch64, and most of these are far more niche than that. As the article mentioned, it seems likely that eventually the ability for certain platforms for get support on new compilers will be a make-or-break for their ability to stay current with upgrades for a lot of the more fundamental packages. Alternatively, I gu

ess, there could be effort to get a new gcc-backend for more langauges; I believe there's an ongoing effort for Rust[2], but who knows down the line what that might look like. Eventually, this will probably need to come to a head. [1] https://gleam.run/ [2] https://github.com/Rust-GCC/gccrs
