--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Perhaps determine_visibility could recurse on DECL_LOCAL_DECL_ALIAS if non-NULL
and perhaps DECL_VISIBILITY (decl) != orig_visibility
|| DECL_VISIBILITY_SPECIFIED (decl) != orig_visibility_specified
?  Though, not really sure what should be done if one does e.g.:

int non_hidden_fetch(void) {                                                    
  extern const int hidden_global;                                               
  return hidden_global;                                                         
}

#pragma GCC visibility push(hidden)                                             

int hidden_fetch(void) {                                                        
  extern const int hidden_global;                                               
  return hidden_global;                                                         
}
etc.
