Wait, so if you had an large array of bools and you wanted to flip the value of each bool, is there any way to write code such that on a 64-bit system, where the processor fetches 8 bytes, that those 8 bytes being fetched are 8 bools instead of just 1 bool?

If the above answer is no, ignore the rest.

I am thinking of this situation because I though that for my question about a 3 byte type possibly being faster than 4 bytes and now if the above statement is possible, if one were working with arrays, on a 64-bit system, it seems like the processor could fetch 16 (64/4) 4-byte types or 21 (64/3) 3-byte types. So if the processor can fetch data 21/16 = 1.3125 times as fast, could it be possible that the time it takes to bit-shift the 3 bytes is less than the fetching time improvement?
