> The bitcode you're referring to is LLVM. It's an architecture-independent assembly It is abstracted over specific CPU instructions, but is not portable and not intended to be. It can contain CPU and OS-specific patterns. It is possible to convert LLVM bytecode into something portable though, or at least a subset of it. That is sort of what Emscripten and PNaCl do.
