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.
