namespace	llvm::slpvectorizer
	A private "module" namespace for types and utilities used by this pass.

Functions
bool	llvm::slpvectorizer::isConstant (Value *V)
bool	llvm::slpvectorizer::isVectorLikeInstWithConstOps (Value *V)
	Checks if V is one of vector-like instructions, i.e.
unsigned	llvm::slpvectorizer::getNumElements (Type *Ty)
unsigned	llvm::slpvectorizer::getPartNumElems (unsigned Size, unsigned NumParts)
	Returns power-of-2 number of elements in a single register (part), given the total number of elements Size and number of registers (parts) NumParts.
unsigned	llvm::slpvectorizer::getNumElems (unsigned Size, unsigned PartNumElems, unsigned Part)
	Returns correct remaining number of elements, considering total amount Size, (power-of-2 number) of elements in a single register PartNumElems and current register (part) Part.
