Louis Gerbarg c0adfbb49d Add ExtractValue instruction to SimplifyCFG's ComputeSpeculationCost ... Since ExtractValue is not included in ComputeSpeculationCost CFGs containing ExtractValueInsts cannot be simplified. In particular this interacts with InstCombineCompare's tendency to insert add.with.overflow intrinsics for certain idiomatic math operations, preventing optimization. This patch adds ExtractValue to the ComputeSpeculationCost. Test case included rdar://14853450 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208434 91177308-0d34-0410-b5e6-96231b3b80d8		2014-05-09 17:02:46 +00:00
