Member Enumeration Documentation

MaskAndShiftConstants

template<typename PointerT , unsigned IntBits, typename PtrTraits >

enum llvm::PointerIntPairInfo::MaskAndShiftConstants : uintptr_t

Enumerator
PointerBitMask	PointerBitMask - The bits that come from the pointer.
IntShift	IntShift - The number of low bits that we reserve for other uses, and keep zero.
IntMask	IntMask - This is the unshifted mask for valid bits of the int type.
