--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think the code should be:
```
  if (priority == DEFAULT_INIT_PRIORITY
      && get_init_priority() == priority)
    return;
```

That is if it is already DEFAULT_INIT_PRIORITY don't do the insert into the
hashtable still; otherwise update the hashtable.
