--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You have an integer overflow in your code which is why the comparisons are
being removed.
if (tmp == INT_MIN)
Can never happen because B is always a positive constant (411), so tmp has a
range of [INT_MIN+411. INT_MAX]. The only way to get INT_MIN is if you had an
overflow and overflows in C are undefined.
