Hal Finkel f21831073c Use GetUnderlyingObjects in misched ... misched used GetUnderlyingObject in order to break false load/store dependencies, and the -enable-aa-sched-mi feature similarly relied on GetUnderlyingObject in order to ensure it is safe to use the aliasing analysis. Unfortunately, GetUnderlyingObject does not recurse through phi nodes, and so (especially due to LSR) all of these mechanisms failed for induction-variable-dependent loads and stores inside loops. This change replaces uses of GetUnderlyingObject with GetUnderlyingObjects (which will recurse through phi and select instructions) in misched. Andy reviewed, tested and simplified this patch; Thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169744 91177308-0d34-0410-b5e6-96231b3b80d8		2012-12-10 18:49:16 +00:00
