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. | |
