[PATCH] D79680: [Attributor] Fix for a crash on RAUW when rewriting function signature

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added a comment.

The fix is somewhat counter intuitive or I do not understand it. Checking if we have uses before replacing *all uses* seems redundant. I guess the different type was the problem, question is if we need the RAUW at all and if so, if the type might be different in other situations.
