The perl and python do not have sufficient modules to do what would be needed by git. The compilers are invoked using a CLI and are not callable using a library. gcc is, for all intents and purposes, not possible - so anything requiring gcc (for example, Rust), cannot be built. There is no back-end pluggable component for any of the compilers. > Ah, no pluggable backend is unfortunate. Rust only uses GCC to build the LLVM backend, it isn't actually needed for the language. It does link libgcc_s for unwinding and I believe some math symbols, but unwinding can be disabled and other symbols can come from anywhere. If you can build mrustc (C++ program) [1] then you can use it to transpile Rust to C. This is how rustc is bootstrapped, and would be how you bring it up with a different backend on a new platform. Still, this probably wouldn't be a solution for git. [1]: https://github.com/thepowersgang/mrustc
