--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a testcase which fails at all optimization levels (not DCEing out
stuff):
int test_cmpu_x;

long
test_cmpu_y() {
  long le;
  f(&le);
  __asm__("cmp %"
          "[x], %"
          "[y]"
          : "=@ccls"(le)
          : [x] ""(test_cmpu_x), [y] ""(test_cmpu_y));
    return le;
}
