Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.
namespace	llvm::slpvectorizer
	A private "module" namespace for types and utilities used by this pass.

Functions
bool	llvm::slpvectorizer::isValidElementType (Type *Ty, bool ReVec)
	Predicate for the element types that the SLP vectorizer supports.
Type *	llvm::slpvectorizer::getValueType (Value *V, bool ReVec, bool LookThroughCmp=false)
	Returns the "element type" of the given value/instruction V.
Type *	llvm::slpvectorizer::getWidenedType (Type *ScalarTy, unsigned VF)
unsigned	llvm::slpvectorizer::getFullVectorNumberOfElements (const TargetTransformInfo &TTI, Type *Ty, unsigned Sz, bool ReVec)
	Returns the number of elements of the given type Ty, not less than Sz, which forms type, which splits by TTI into whole vector types during legalization.
unsigned	llvm::slpvectorizer::getFloorFullVectorNumberOfElements (const TargetTransformInfo &TTI, Type *Ty, unsigned Sz, bool ReVec)
	Returns the number of elements of the given type Ty, not greater than Sz, which forms type, which splits by TTI into whole vector types during legalization.
FixedVectorType *	llvm::slpvectorizer::getMaskedDivRemType (const TargetTransformInfo &TTI, unsigned Opcode, Type *ScalarTy, unsigned NumElts, bool ReVec)
	For a non-power-of-2 NumElts-wide integer div/rem Opcode, returns the padded full-register vector type if padding is structurally possible, or nullptr if the vector already fills a register or the opcode is not div/rem.
bool	llvm::slpvectorizer::hasFullVectorsOrPowerOf2 (const TargetTransformInfo &TTI, Type *Ty, unsigned Sz, bool ReVec)
	Returns true if widened type of Ty elements with size Sz represents full vector type, i.e.
bool	llvm::slpvectorizer::isAllowedNonPowerOf2VF (unsigned NumElts, bool AllowNonPowerOf2)
	True when AllowNonPowerOf2 is set and NumElts is a supported non-power-of-2 width: NumElts + 1 must be a power of two (e.g.
unsigned	llvm::slpvectorizer::getNumberOfParts (const TargetTransformInfo &TTI, Type *VecTy, Type *ScalarTy, bool ReVec, unsigned Limit=std::numeric_limits< unsigned >::max())
	Returns number of parts, the type VecTy will be split at the codegen phase.
