isADDADDMUL()

static bool isADDADDMUL ( SDValue  Op, SDValue &  Mul0, SDValue &  Mul1, SDValue &  Addend0, SDValue &  Addend1, bool  requireIntermediatesHaveOneUse  )

static

isADDADDMUL - Return whether Op is in a form that is equivalent to add(add(mul(x,y),a),b).

If requireIntermediatesHaveOneUse is true then each intermediate result in the calculation must also have a single use. If the Op is in the correct form the constituent parts are written to Mul0, Mul1, Addend0 and Addend1.
