Adam Nemet 0ea25c2e64 [LoopAccesses] Create the analysis pass ... This is a function pass that runs the analysis on demand. The analysis can be initiated by querying the loop access info via LAA::getInfo. It either returns the cached info or runs the analysis. Symbolic stride information continues to reside outside of this analysis pass. We may move it inside later but it's not a priority for me right now. The idea is that Loop Distribution won't support run-time stride checking at least initially. This means that when querying the analysis, symbolic stride information can be provided optionally. Whether stride information is used can invalidate the cache entry and rerun the analysis. Note that if the loop does not have any symbolic stride, the entry should be preserved across Loop Distribution and LV. Since currently the only user of the pass is LV, I just check that the symbolic stride information didn't change when using a cached result. On the LV side, LoopVectorizationLegality requests the info object corresponding to the loop from the analysis pass. A large chunk of the diff is due to LAI becoming a pointer from a reference. A test will be added as part of the -analyze patch. Also tested that with AVX, we generate identical assembly output for the testsuite (including the external testsuite) before and after. This is part of the patchset that converts LoopAccessAnalysis into an actual analysis pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229893 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-19 19:15:04 +00:00
