Functions
unsigned	llvm::getDefaultMaxUsesToExploreForCaptureTracking ()
	getDefaultMaxUsesToExploreForCaptureTracking - Return default value of the maximal number of uses to explore before giving up.
bool	llvm::PointerMayBeCaptured (const Value *V, bool ReturnCaptures, bool StoreCaptures, unsigned MaxUsesToExplore=0)
	PointerMayBeCaptured - Return true if this pointer value may be captured by the enclosing function (which is required to exist).
bool	llvm::PointerMayBeCapturedBefore (const Value *V, bool ReturnCaptures, bool StoreCaptures, const Instruction *I, const DominatorTree *DT, bool IncludeI=false, unsigned MaxUsesToExplore=0, const LoopInfo *LI=nullptr)
	PointerMayBeCapturedBefore - Return true if this pointer value may be captured by the enclosing function (which is required to exist).
Instruction *	llvm::FindEarliestCapture (const Value *V, Function &F, bool ReturnCaptures, bool StoreCaptures, const DominatorTree &DT, unsigned MaxUsesToExplore=0)
UseCaptureKind	llvm::DetermineUseCaptureKind (const Use &U, llvm::function_ref< bool(Value *, const DataLayout &)> IsDereferenceableOrNull)
	Determine what kind of capture behaviour U may exhibit.
void	llvm::PointerMayBeCaptured (const Value *V, CaptureTracker *Tracker, unsigned MaxUsesToExplore=0)
	PointerMayBeCaptured - Visit the value and the values derived from it and find values which appear to be capturing the pointer value.
bool	llvm::isNonEscapingLocalObject (const Value *V, SmallDenseMap< const Value *, bool, 8 > *IsCapturedCache=nullptr)
	Returns true if the pointer is to a function-local object that never escapes from the function.
