* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-421/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [InstCombine] Canonicalize variable mask in masked mergeRoman Lebedev2018-04-281-54/+36
| | | | | | | | | | | | | | | | | | | 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
