Public Member Functions inherited from llvm::LinearPolySize< TypeSize >
ScalarTy	getKnownMinValue () const
	Returns the minimum value this size can represent. More...

bool	isScalable () const
	Returns whether the size is scaled by a runtime quantity (vscale). More...

bool	isKnownEven () const
	A return value of true indicates we know at compile time that the number of elements (vscale * Min) is definitely even. More...

bool	isKnownMultipleOf (ScalarTy RHS) const
	This function tells the caller whether the element count is known at compile time to be a multiple of the scalar value RHS. More...

ScalarTy	getFixedValue () const

TypeSize	divideCoefficientBy (ScalarTy RHS) const
	We do not provide the '/' operator here because division for polynomial types does not work in the same way as for normal integer types. More...

TypeSize	coefficientNextPowerOf2 () const

bool	hasKnownScalarFactor (const LinearPolySize &RHS) const
	Returns true if there exists a value X where RHS.multiplyCoefficientBy(X) will result in a value whose size matches our own. More...

ScalarTy	getKnownScalarFactor (const LinearPolySize &RHS) const
	Returns a value X where RHS.multiplyCoefficientBy(X) will result in a value whose size matches our own. More...
