WebThe boost::high_bit_mask_t class template provides constants for bit masks representing the bit at a certain position. The masks are equivalent to the value 2 Bit, where Bit is the template parameter. The bit position must be a nonnegative number from zero to Max, where Max is one less than the number of bits supported by the largest unsigned built-in … Web24 de jan. de 2024 · Let’s work backwards. 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.
