  else if (! VAR_OR_FUNCTION_DECL_P (decl)
           && TREE_CODE (decl) != FIELD_DECL)
    {
      error ("alignment may not be specified for %q+D", decl);
      *no_add_attrs = true;
    }

Here we have PARM_DECL which is not VAR or FUNCTION DECL.

This is at least a diagnostic issue where we should at least say it is not
allowed for arguments.
