MAD Multiply-add vectors (predicated), writing multiplicand [Zdn = Za + Zdn * Zm] Multiply the corresponding active elements of the first and second source vectors and add to elements of the third (addend) vector. Destructively place the results in the destination and first source (multiplicand) vector. Inactive elements in the destination vector register remain unmodified.
