Member Data Documentation

AAMDNodes llvm::AliasAnalysis::Location::AATags

AATags - The metadata nodes which describes the aliasing of the location (each member is null if that kind of information is unavailable)..

Definition at line 119 of file AliasAnalysis.h.

Referenced by llvm::DenseMapInfo< AliasAnalysis::Location >::getHashValue(), getWithoutAATags(), and llvm::DenseMapInfo< AliasAnalysis::Location >::isEqual().

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

Ptr - The address of the start of the location.

Definition at line 109 of file AliasAnalysis.h.

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
