If you really needed to run Rust code on some platform LLVM doesn’t natively support, it does allow you to compile to C. Presumably you could then compile that using whatever C compiler works for your platform. Although Rust is not as portable as C, going through these hoops would mean that —- modulo codegen bugs —- the generated C code should still be as memory-safe as the original Rust code.
