--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Yes the code is undefined/unspecified.
quo_lo in one case does not fit into the range of unsigned int while quo_high
does not fit into the range of int. So you need to first cast to int64_t (long
or long long) and then cast to uint32_t for this code to be well defined.
