> For example, signed integer overflow being UB was intended to allow compiling C to non-twos-compliment machines. This is indeed a design mistake, but in another sense. Ordinary arithmetic ops like + or - should throw an exception on overflow (with both signed and unsigned operands) because most of the times you need an ordinary math, not math modulo 2^32. For those rare cases where wrap around is desired, there should be a function like add_and_wrap() or a special operator. |
