Protected Member Functions inherited from llvm::detail::PtrUseVisitorBase
	PtrUseVisitorBase (const DataLayout &DL)
	Note that the constructor is protected because this class must be a base class, we can't create instances directly of this class.
void	enqueueUsers (Value &I)
	Enqueue the users of this instruction in the visit worklist.
bool	adjustOffsetForGEP (GetElementPtrInst &GEPI)
	Walk the operands of a GEP and adjust the offset as appropriate.
Protected Attributes inherited from llvm::detail::PtrUseVisitorBase
const DataLayout &	DL
PtrInfo	PI
	The info collected about the pointer being visited thus far.
SmallVector< UseToVisit, 8 >	Worklist
	The worklist of to-visit uses.
SmallPtrSet< Use *, 8 >	VisitedUses
	A set of visited uses to break cycles in unreachable code.
Use *	U
	The use currently being visited.
bool	IsOffsetKnown
	True if we have a known constant offset for the use currently being visited.
APInt	Offset
	The constant offset of the use if that is known.

Detailed Description

Builder for the alloca slices.

This class builds a set of alloca slices by recursively visiting the uses of an alloca and making a slice for each load and store at each offset.
