From 559742c0eae0a7368eb5f67cde7a3599eaf82ade Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Thu, 26 Jul 2007 16:14:06 +0000 Subject: [PATCH] Fix the alias analysis query in DAGCombiner to not add in two offsets. The SrcValueOffset values are the real offsets from the SrcValue base pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40534 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/DAGCombiner.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/CodeGen/SelectionDAG/DAGCombiner.cpp b/lib/CodeGen/SelectionDAG/DAGCombiner.cpp index 22c6e6b396c..b38b479cbe8 100644 --- a/lib/CodeGen/SelectionDAG/DAGCombiner.cpp +++ b/lib/CodeGen/SelectionDAG/DAGCombiner.cpp @@ -4599,8 +4599,8 @@ bool DAGCombiner::isAlias(SDOperand Ptr1, int64_t Size1, if (CombinerGlobalAA) { // Use alias analysis information. - int Overlap1 = Size1 + SrcValueOffset1 + Offset1; - int Overlap2 = Size2 + SrcValueOffset2 + Offset2; + int Overlap1 = Size1 + SrcValueOffset1; + int Overlap2 = Size2 + SrcValueOffset2; AliasAnalysis::AliasResult AAResult = AA.alias(SrcValue1, Overlap1, SrcValue2, Overlap2); if (AAResult == AliasAnalysis::NoAlias) -- 2.34.1
