Re: GCC optimizes integer overflow: bug or feature?


Or you can do, since elsewhere in the code you compute time_t_max:

for (j = 1; j <= time_t_max / 2 + 1; j *= 2)

No, this does not work. It would work to have:

  for (j = 1;;)
    {
      if (j > time_t_max / 2)
        break;
      j *= 2;
    }

Oops.
