Public Member Functions

constexpr TypeSize (ScalarTy Quantity, bool Scalable)
 operator ScalarTy () 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 isFixed () const
 Returns true if the quantity is not scaled by 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 coefficientNextPowerOf2 () const
constexpr bool hasKnownScalarFactor (const FixedOrScalableQuantity &RHS) const
 Returns true if there exists a value X where RHS*X will result in a value whose quantity matches our own.
constexpr ScalarTy getKnownScalarFactor (const FixedOrScalableQuantity &RHS) const
 Returns a value X where RHS*X will result in a value whose quantity matches our own.
void print (raw_ostream &OS) const
 Printing function.
