--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Testcase without includes:
bool a, b;
int d, c;

const int &
foo (const int &f, const int &g)
{
  return !f ? f : g;
}

__attribute__((noipa)) void
bar (int)
{
}

int
main ()
{
  c = foo (b, 0) > ((b ? d : b) ?: 8);
  a = b ? d : b;
  bar (a);
  if (a != 0)
    __builtin_abort ();
}
