--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You can still use %= if you want and combine it with the input constraint with
counter.
That is:
void y (int a) {
    if (a)
        asm("# %="::"i"(__COUNTER__));
    else
        asm("# %="::"i"(__COUNTER__));
}

That way if you still get the same version to use between the two compilers if
clang does not have __COUNTER__.
