 Public Member Functions inherited from llvm::LinearPolySize< ElementCount > | |
| 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 |
| ElementCount | 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... | |
| ElementCount | multiplyCoefficientBy (ScalarTy RHS) const |
| ElementCount | 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... | |
