From d517da33b712b5d8d687ee5e5974056a4787ec4f Mon Sep 17 00:00:00 2001 From: Arnold Schwaighofer Date: Thu, 14 Mar 2013 18:54:36 +0000 Subject: LoopVectorize: Invert case when we use a vector cmp value to query select cost We generate a select with a vectorized condition argument when the condition is NOT loop invariant. Not the other way around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177098 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Vectorize/LoopVectorize.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/Transforms/Vectorize/LoopVectorize.cpp') diff --git a/lib/Transforms/Vectorize/LoopVectorize.cpp b/lib/Transforms/Vectorize/LoopVectorize.cpp index 07dd453424..930d9c412f 100644 --- a/lib/Transforms/Vectorize/LoopVectorize.cpp +++ b/lib/Transforms/Vectorize/LoopVectorize.cpp @@ -3338,7 +3338,7 @@ LoopVectorizationCostModel::getInstructionCost(Instruction *I, unsigned VF) { const SCEV *CondSCEV = SE->getSCEV(SI->getCondition()); bool ScalarCond = (SE->isLoopInvariant(CondSCEV, TheLoop)); Type *CondTy = SI->getCondition()->getType(); - if (ScalarCond) + if (!ScalarCond) CondTy = VectorType::get(CondTy, VF); return TTI.getCmpSelInstrCost(I->getOpcode(), VectorTy, CondTy); -- cgit v1.2.3-18-g5258
