Reduced testcase:
struct a
{
unsigned int bits : 1;
signed long val : ((sizeof(long) * 8) - 1);
};
int Fnegate (struct a b)
{
if ((-((long)b.val)) <= ((long) ((1UL << (((sizeof(long) * 8) - 1) - 1))
-1UL)) && (-((long)b.val)) >= (-(((long) ((1UL << (((sizeof(long) * 8) - 1) -
1)) -1UL))) - 1))
return 0 ;
abort ();
}
int main ()
{
struct a b = {1, 1};
Fnegate (b);
return 0;
}
