Member Data Documentation

◆ AccessType

llvm::MDNode* clang::CodeGen::TBAAAccessInfo::AccessType

AccessType - The final access type.

May be null if there is no TBAA information available about this access.

Referenced by clang::CodeGen::CodeGenFunction::EmitLValueForField(), clang::CodeGen::CodeGenTBAA::getAccessTagInfo(), llvm::DenseMapInfo< clang::CodeGen::TBAAAccessInfo >::getHashValue(), operator==(), TBAAAccessInfo(), TBAAAccessInfo(), and TBAAAccessInfo().

◆ BaseType

llvm::MDNode* clang::CodeGen::TBAAAccessInfo::BaseType

BaseType - The base/leading access type.

May be null if this access descriptor represents an access that is not considered to be an access to an aggregate or union member.

Definition at line 101 of file CodeGenTBAA.h.

Referenced by clang::CodeGen::CodeGenFunction::EmitLValueForField(), clang::CodeGen::CodeGenTBAA::getAccessTagInfo(), llvm::DenseMapInfo< clang::CodeGen::TBAAAccessInfo >::getHashValue(), operator==(), TBAAAccessInfo(), and TBAAAccessInfo().

◆ Kind

TBAAAccessKind clang::CodeGen::TBAAAccessInfo::Kind

Kind - The kind of the access descriptor.

Definition at line 96 of file CodeGenTBAA.h.

Referenced by llvm::DenseMapInfo< clang::CodeGen::TBAAAccessInfo >::getHashValue(), isIncomplete(), isMayAlias(), operator==(), and TBAAAccessInfo().

◆ Offset

uint64_t clang::CodeGen::TBAAAccessInfo::Offset

Offset - The byte offset of the final access within the base one.

Must be zero if the base access type is not specified.

Referenced by clang::CodeGen::CodeGenFunction::EmitLValueForField(), clang::CodeGen::CodeGenTBAA::getAccessTagInfo(), llvm::DenseMapInfo< clang::CodeGen::TBAAAccessInfo >::getHashValue(), operator==(), TBAAAccessInfo(), and TBAAAccessInfo().

◆ Size

uint64_t clang::CodeGen::TBAAAccessInfo::Size

Size - The size of access, in bytes.
