Public Member Functions
constexpr	TypeSize (ScalarTy Quantity, bool Scalable)

constexpr ScalarTy	getFixedSize () const

constexpr ScalarTy	getKnownMinSize () const

Public Member Functions inherited from llvm::details::FixedOrScalableQuantity< TypeSize, uint64_t >
constexpr bool	operator== (const FixedOrScalableQuantity &RHS) const

constexpr bool	operator!= (const FixedOrScalableQuantity &RHS) const

constexpr bool	isZero () const

constexpr bool	isNonZero () const

	operator bool () const

constexpr TypeSize	getWithIncrement (ScalarTy RHS) const
	Add `RHS` to the underlying quantity.

constexpr ScalarTy	getKnownMinValue () const
	Returns the minimum value this quantity can represent.

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

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

constexpr 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.

constexpr ScalarTy	getFixedValue () const

constexpr 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.

constexpr TypeSize	multiplyCoefficientBy (ScalarTy RHS) const

constexpr TypeSize	coefficientNextPowerOf2 () const

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

constexpr ScalarTy	getKnownScalarFactor (const FixedOrScalableQuantity &RHS) const
	Returns a value X where RHS.multiplyCoefficientBy(X) will result in a value whose quantity matches our own.

void	print (raw_ostream &OS) const
	Printing function.
