[PATCH] D112955: [InstCombine] (~(a | b) & c) | ~(c | (a ^ b)) -> ~((a | b) & (c | (b ^ a)))

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec updated this revision to Diff 389580.
rampitec added a comment.

The patch was reverted since the flipped case produces more undefined result. I am not sure how did that sneak, but I am reopening it and limiting to only 'or' case.
