Roman Lebedev 4f96d992a3 [InstCombine] Canonicalize variable mask in masked merge ... Summary: Masked merge has a pattern of: `((x ^ y) & M) ^ y`. But, there is no difference between `((x ^ y) & M) ^ y` and `((x ^ y) & ~M) ^ x`, We should canonicalize the pattern to non-inverted mask. https://rise4fun.com/Alive/Yol Reviewers: spatel, craig.topper Reviewed By: spatel Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D45664 llvm-svn: 331112		2018-04-28 15:45:07 +00:00
