The comment documenting how bitwise expressions work includes a table which summarizes the mask and xor arguments combined to express the supported boolean operations. However, the row for OR: mask xor 0 x is incorrect. dreg = (sreg & 0) ^ x is not equivalent to: dreg = sreg | x What the code actually does is: dreg = (sreg & ~x) ^ x Update the documentation to match.
