Eric Christopher	598198edbc	Revert "Temporarily Revert "Add basic loop fusion pass."" ... The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@358552 91177308-0d34-0410-b5e6-96231b3b80d8	2019-04-17 04:52:47 +00:00
Eric Christopher	02cc44c1b9	Temporarily Revert "Add basic loop fusion pass." ... As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@358546 91177308-0d34-0410-b5e6-96231b3b80d8	2019-04-17 02:12:23 +00:00
Daniel Neilson	974321bd67	[LV] Preserve inbounds on created GEPs ... Summary: This is a fix for PR23997. The loop vectorizer is not preserving the inbounds property of GEPs that it creates. This is inhibiting some optimizations. This patch preserves the inbounds property in the case where a load/store is being fed by an inbounds GEP.

Matthew Simpson	0749c8e439	[LV] Scalarize instructions marked scalar after vectorization ... This patch ensures that we actually scalarize instructions marked scalar after vectorization. Previously, such instructions may have been vectorized instead.
