From b37a73d5c6a0c8bb1f6e363d3b53980e4fa0cead Mon Sep 17 00:00:00 2001 From: Manman Ren Date: Thu, 4 Apr 2013 21:53:22 +0000 Subject: Initial support for struct-path aware TBAA. Added TBAABaseType and TBAAOffset in LValue. These two fields are initialized to the actual type and 0, and are updated in EmitLValueForField. Path-aware TBAA tags are enabled for EmitLoadOfScalar and EmitStoreOfScalar. Added command line option -struct-path-tbaa. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178797 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CodeGenModule.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'lib/CodeGen/CodeGenModule.h') diff --git a/lib/CodeGen/CodeGenModule.h b/lib/CodeGen/CodeGenModule.h index fcd48302ae..5b2153e5ff 100644 --- a/lib/CodeGen/CodeGenModule.h +++ b/lib/CodeGen/CodeGenModule.h @@ -501,6 +501,11 @@ public: llvm::MDNode *getTBAAInfo(QualType QTy); llvm::MDNode *getTBAAInfoForVTablePtr(); llvm::MDNode *getTBAAStructInfo(QualType QTy); + /// Return the MDNode in the type DAG for the given struct type. + llvm::MDNode *getTBAAStructTypeInfo(QualType QTy); + /// Return the path-aware tag for given base type, access node and offset. + llvm::MDNode *getTBAAStructTagInfo(QualType BaseTy, llvm::MDNode *AccessN, + uint64_t O); bool isTypeConstant(QualType QTy, bool ExcludeCtorDtor); -- cgit v1.2.3-70-g09d2
