d = vec_mulh(a, b)Returns a vector containing the most significant ("high") half of results of performing a multiply operation using the given vectors. This function multiplies corresponding elements in the given vectors, the most significant half of the double element-sized product is assigned to the result of the corresponding elements in the result vector.
