Member Data Documentation

int64_t llvm::MachinePointerInfo::Offset

Offset - This is an offset from the base Value*.

Definition at line 43 of file MachineMemOperand.h.

Referenced by llvm::MachineMemOperand::getOffset(), getWithOffset(), and llvm::MachineMemOperand::setOffset().

PointerUnion<const Value *, const PseudoSourceValue *> llvm::MachinePointerInfo::V

V - This is the IR pointer value for the access, or it is null if unknown.

If this is null, then the access is to a pointer in the default address space.
