Other than moving code and adding the boilerplate for the new files, the code being moved is unchanged. There are a few global functions that are shared with the rest of the LoopVectorizer. I moved these to the new module as well (emitLoopAnalysis, stripIntegerCast, replaceSymbolicStrideSCEV) along with the Report class used by emitLoopAnalysis. There is probably room for further improvement in this area. I kept DEBUG_TYPE "loop-vectorize" because it's used as the PassName with emitOptimizationRemarkAnalysis. This will obviously have to change. NFC. This is part of the patchset that splits out the memory dependence logic from LoopVectorizationLegality into a new class LoopAccessAnalysis. LoopAccessAnalysis will be used by the new Loop Distribution pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227756 91177308-0d34-0410-b5e6-96231b3b80d8
