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

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

What is the motivation for this patch? The added tests should already get folded before reaching the backend (by InstCombine). We should only add folds to DAGCombine if the folded pattern is created by legalization. What is the original context for this change?
