#include "llvm/Analysis/LoopAccessAnalysis.h"

Public Member Functions
	PointerInfo (Value *PointerValue, const SCEV *Start, const SCEV *End, bool IsWritePtr, unsigned DependencySetId, unsigned AliasSetId, const SCEV *Expr, bool NeedsFreeze)

Public Attributes
TrackingVH< Value >	PointerValue
	Holds the pointer value that we need to check.
const SCEV *	Start
	Holds the smallest byte address accessed by the pointer throughout all iterations of the loop.
const SCEV *	End
	Holds the largest byte address accessed by the pointer throughout all iterations of the loop, plus 1.
bool	IsWritePtr
	Holds the information if this pointer is used for writing to memory.
unsigned	DependencySetId
	Holds the id of the set of pointers that could be dependent because of a shared underlying object.
unsigned	AliasSetId
	Holds the id of the disjoint alias set to which this pointer belongs.
const SCEV *	Expr
	SCEV for the access.
bool	NeedsFreeze
	True if the pointer expressions needs to be frozen after expansion.
