From b2143b6247901ae4eca2192ee134564c4f5f7853 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Tue, 14 Sep 2010 21:25:10 +0000 Subject: Remove the experimental AliasAnalysis::getDependency interface, which isn't a good level of abstraction for memdep. Instead, generalize AliasAnalysis::alias and related interfaces with a new Location class for describing a memory location. For now, this is the same Pointer and Size as before, plus an additional field for a TBAA tag. Also, introduce a fixed MD_tbaa metadata tag kind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113858 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/AliasDebugger.cpp | 23 ++++++++++++----------- 1 file changed, 12 insertions(+), 11 deletions(-) (limited to 'lib/Analysis/AliasDebugger.cpp') diff --git a/lib/Analysis/AliasDebugger.cpp b/lib/Analysis/AliasDebugger.cpp index b9fe64608c..82e705dd1c 100644 --- a/lib/Analysis/AliasDebugger.cpp +++ b/lib/Analysis/AliasDebugger.cpp @@ -92,17 +92,18 @@ namespace { //------------------------------------------------ // Implement the AliasAnalysis API // - AliasResult alias(const Value *V1, unsigned V1Size, - const Value *V2, unsigned V2Size) { - assert(Vals.find(V1) != Vals.end() && "Never seen value in AA before"); - assert(Vals.find(V2) != Vals.end() && "Never seen value in AA before"); - return AliasAnalysis::alias(V1, V1Size, V2, V2Size); + AliasResult alias(const Location &LocA, const Location &LocB) { + assert(Vals.find(LocA.Ptr) != Vals.end() && + "Never seen value in AA before"); + assert(Vals.find(LocB.Ptr) != Vals.end() && + "Never seen value in AA before"); + return AliasAnalysis::alias(LocA, LocB); } ModRefResult getModRefInfo(ImmutableCallSite CS, - const Value *P, unsigned Size) { - assert(Vals.find(P) != Vals.end() && "Never seen value in AA before"); - return AliasAnalysis::getModRefInfo(CS, P, Size); + const Location &Loc) { + assert(Vals.find(Loc.Ptr) != Vals.end() && "Never seen value in AA before"); + return AliasAnalysis::getModRefInfo(CS, Loc); } ModRefResult getModRefInfo(ImmutableCallSite CS1, @@ -110,9 +111,9 @@ namespace { return AliasAnalysis::getModRefInfo(CS1,CS2); } - bool pointsToConstantMemory(const Value *P) { - assert(Vals.find(P) != Vals.end() && "Never seen value in AA before"); - return AliasAnalysis::pointsToConstantMemory(P); + bool pointsToConstantMemory(const Location &Loc) { + assert(Vals.find(Loc.Ptr) != Vals.end() && "Never seen value in AA before"); + return AliasAnalysis::pointsToConstantMemory(Loc); } virtual void deleteValue(Value *V) { -- cgit v1.2.3-18-g5258
