Because of the mask, the expression returns 0 if there are no “high” bits set in any of the bytes of test. So we must show that no high bits in test are set. Now, test is generated as the bitwise and of v_sub_ones and notv, so we must show that for each byte’s high bit, it is either 0 in v_sub_ones or it is 0 in notv. irs e service account loginWeb3: High.
