[PATCH] D57149: [StackProtector] Skip analysing dead users in HasAddressTaken, PR40436

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

An alternative way to handle this would be to remove unreachable code. I'm surprised unreachable code reaches this pass in a normal pipeline. I thought CGP removed it in normal operation, even at O0. However, removing unreachable code might invalidate the domtree (unless our utility for that updates it?).
