--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Adjusted testcase that just aborts if miscompiled rather than hangs (and
doesn't print anything):
__attribute__((noipa)) void
foo (const char *x)
{
  asm volatile ("" : "+g" (x) : : "memory");
  if (x)
    __builtin_abort ();
}

int a, b = 1;

int
main ()
{
  while (1) 
    {
      unsigned long long d = 18446744073709551615UL; 
      while (1)
        {
          int e = b;
          while (d < 2) 
            foo ("0"); 
          if (a)
            d++;
          if (b)
            break;
        }
      break;
    }
  return 0; 
}
