> There's no notion of "PC" in wasm, no? You cannot take an address of a function and call it indirectly later. Well, you can do that, but what you get is not an address in the regular mean. It's an index, if I understand correctly. So, by PC, what do you mean?


For now, bytecode offset (function or file relative) is used in role of the PC -- for call stack, for profiler, and we also successfully adapted it for source maps. I'm not sure what moving to index (of wasm operator?) base will change, but it will only will add complexity and will not solve this particular issue.
