[PATCH] D86578: [TargetLowering] Combine known bits for icmp in SimplifySetCC (PR41182)

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

To repeat my previous question, because it's not obvious from tests: Which legalizations does this improve? That is, for input IR that has already gone through the `opt -O2` pipeline, which cases does this improve?
