--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Slightly reduced:
int
foo (_BitInt(7) x)
{
return __builtin_mul_overflow_p (x,
1046555807606105294475452482332716433408wb, 0);
}
Ugh, another special case where we don't detect the need to lower, next to
storing large/huge INTEGER_CSTs or the large/huge INTEGER_CST to floating
casts.
