Classes
struct	llvm::VFRange
	A range of powers-of-2 vectorization factors with fixed start and adjustable end. More...
class	llvm::VFRange::iterator
	Iterator to iterate over vectorization factors in a VFRange. More...
class	llvm::VPLane
	In what follows, the term "input IR" refers to code that is fed into the vectorizer whereas the term "output IR" refers to code that is generated by the vectorizer. More...
struct	llvm::VPTransformState
	VPTransformState holds information passed down when "executing" a VPlan, needed for generating the output IR. More...
struct	llvm::VPTransformState::DataState
struct	llvm::VPTransformState::CFGState
	Hold state information used when constructing the CFG of the output IR, traversing the VPBasicBlocks and generating corresponding IR BasicBlocks. More...
struct	llvm::VPCostContext
	Struct to hold various analysis needed for cost computations. More...
class	llvm::VPSlotTracker
	This class can be used to assign names to VPValues. More...
class	llvm::VPlanPrinter
	VPlanPrinter prints a given VPlan to a given output stream. More...

Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Functions
Value *	llvm::getRuntimeVF (IRBuilderBase &B, Type *Ty, ElementCount VF)
	Return the runtime value for VF.
Value *	llvm::createStepForVF (IRBuilderBase &B, Type *Ty, ElementCount VF, int64_t Step)
	Return a value for Step multiplied by VF.
unsigned	llvm::getPredBlockCostDivisor (TargetTransformInfo::TargetCostKind CostKind)
	A helper function that returns how much we should divide the cost of a predicated block by.
bool	llvm::canConstantBeExtended (const APInt *C, Type *NarrowType, TTI::PartialReductionExtendKind ExtKind)
	Check if a constant CI can be safely treated as having been extended from a narrower type with the given extension kind.
