if (h->root.type != bfd_link_hash_undefined
&& h->root.type != bfd_link_hash_undefweak)
- return NULL;
+ {
+ /* PR 20022 */
+ if (sec_name && info->gc_sections && h->root.u.undef.section == NULL)
+ info->callbacks->einfo (_("%X%P: error: undefined orphan section symbol
%s suggests that garbage collection failed\n"),
+ h->root.root.string);
+ return NULL;
}
Is it safe to check h->root.u.undef.section for defined symbol?
