Did you actually look at these?

This is just a frontend. It uses Cranelift as the backend. It's missing some fairly basic language features like bitfields and variadic functions. And if I'm reading the documentation right, it requires all the source code to be in a single file...

This will compile basically no real-world code. The only supported data type is "int".

This is just a frontend. It uses LLVM as the backend.
Look at what those compilers are capable of compiling and to which targets, and compare it to what this compiler can do. Those are wonderful, and I have nothing but respect for them, but they aren't going to be compiling the Linux kernel.
replyI just did a quick Google search only on GitHub, maybe there are better ones out there on the internet?

Can't compile the Linux kernel, and ironically, also partly written by Claude.

replyA genuinely impressive effort, but alas, still missing some pretty critical features (const, floating point, bools, inline, anonymous structs in function args).
