JVMs also produce machine code ;) In practice LLVM is designed for C/C++ like languages. You can use it for other things but not easily. GraalVM is the closest

JVMs also produce machine code ;) In practice LLVM is designed for C/C++ like languages. You can use it for other things but not easily. GraalVM is the closest thing to a universal VM so far, but even then, it's more optimized for high level languages than stuff like Rust (even though it can run those).
