[PATCH] D108122: FunctionAttrs: do not mark coroutines with odd return path `noreturn`

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added a comment.

This sounds weird. Trying to map this to "regular semantics" coro_end seems to be able to unwind in a way that can happen also in `nounwind` contexts. I'd assume that can probably break the next few implicit assumptions somewhere.
Is there a reason we don't branch to a return on from the coro_end depending on the result?
