LLVM: llvm::detail::PtrUseVisitorBase Class Reference (original) (raw)

Classes
class	PtrInfo
	This class provides information about the result of a visit. More...
struct	UseToVisit
	A struct of the data needed to visit a particular use. More...

Protected Member Functions
	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
const DataLayout &	DL
Visitation infrastructure
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.
Per-visit state
This state is reset for each instruction visited.
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.

See [PtrUseVisitor](classllvm%5F1%5F1PtrUseVisitor.html "A base class for visitors over the uses of a pointer value.") for the public interface and detailed comments about usage. This class is just a helper base class which is not templated and contains all common code to be shared between different instantiations of PtrUseVisitor.
