--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:
__attribute__((noinline, noclone)) unsigned __int128
foo (unsigned __int128 x, unsigned long long y)
{
  return x + (unsigned long long) -y;
}

int
main ()
{
  if (foo (70, 0) != 70)
    __builtin_abort ();
  return 0;
}
