You're right, I read diagonally :) However, the optimization argument for signed overflow seems weird to me, because I can't see any reason why this argument would not apply to unsigned overflow as well. If we keep undefined behavior to optimize things like "if (n < n + 1)" when n is signed, why not do the same when n is unsigned? Conversely, if there is a good reason not to, then why would it not apply to signed overflow as well? |
