No worries - it depends on what your constraints and context are. It's fundamentally something a wasm-emitting compiler cannot solve performantly in general. You can use trampolines, as the sibling comments mention, but you'll take a heavy performance hit. If we stretch things too far we'll end up in the "wasm is Turing-complete and thus can run anything" type of territory - if you're doing something performance intensive, say x86 virtualization like I believe apignotti is at Leaning Tech, I think it's fair to describe the problem as unsolvable by the compiler.
