[PATCH] D62210: [WebAssembly] Implement __builtin_return_address for emscripten

[Sam Clegg via Phabricator via llvm-commits]

sbc100 added a comment.

Actually what happens right now if you *don't* land this?  Will it result in `link error: undefined symbol __builtin_return_address`?

Is so, why not just make __builtin_return_address and alias for emscripten_return_address in emscripten and avoid this change completely?
