If we want to represent a subset of this set then it can be encoded by a sequence of N bits (we usually call this sequence a “mask”). In our chosen subset the i-th element belongs to it if and only if the i-th bit of the mask is set i.e., it equals to 1.

"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. " - High bits mask
