--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
waccess is way early where there is almost no optimizations happen.
Not going to fix this.
Simple testcase:
int test_cas_atomic_relaxed_consume_char (char* val, char* foo, char* bar) {
 int model_s = 0;
 int model_f = 1;
 if (model_s < model_f) return 0;
 if (model_f == 3 || model_f == 4) return 0;
 return __atomic_compare_exchange_n (val, foo, bar, 0, model_s, model_f);
}
