Is there a C compiler that works on NonStop and Linux? I ask because I'm wondering if code from gccrs could help with augmenting that compiler. From what I understand gccrs is written in C++17, but Rust's native approach uses mrustc to bootstrap, and then the rest of the Rust compiler is written in Rust. I don't have $500,000 to spare for testing on real NonStop hardware, but if there was a C compiler that worked on NonStop and Linux then there'd at least be the possibility of people trying to make Rust work with it.
