Member Data Documentation

const Value* llvm::AliasAnalysis::Location::Ptr

Ptr - The address of the start of the location.

Referenced by llvm::AliasAnalysis::callCapturesBefore(), llvm::MemoryDependenceAnalysis::getDependency(), llvm::DenseMapInfo< AliasAnalysis::Location >::getHashValue(), llvm::MemoryDependenceAnalysis::getNonLocalPointerDependency(), llvm::MemoryDependenceAnalysis::getPointerDependencyFrom(), getWithNewPtr(), llvm::DenseMapInfo< AliasAnalysis::Location >::isEqual(), isLoadLoadClobberIfExtendedToFullWidth(), isOverwrite(), and isPossibleSelfRead().

uint64_t llvm::AliasAnalysis::Location::Size

Size - The maximum size of the location, in address-units, or UnknownSize if the size is not known. Note that an unknown size does not mean the pointer aliases the entire virtual address space, because there are restrictions on stepping out of one object and into another. See http://llvm.org/docs/LangRef.html#pointeraliasing

const MDNode* llvm::AliasAnalysis::Location::TBAATag

TBAATag - The metadata node which describes the TBAA type of the location, or null if there is no known unique tag.
