If there exists a use of a build_vector that's the bitwise complement of the mask, then transform the node to (and (xor x, (build_vector -1,-1,-1,-1)), (build_vector ~c1,~c2,~c3,~c4)). Since this transformation is only useful when 1) the given build_vector will become a load from constpool, and 2) (and (xor x -1), y) matches to a single instruction, I decided this is appropriate as a x86 specific transformation. rdar://7323335 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96389 91177308-0d34-0410-b5e6-96231b3b80d8 |
