The record_got_page_entry function records and updates the maximum number of GOT page entries which may be required by an object. In the case where an existing GOT page entry was expanded, only the entry belonging to output GOT would have its page count updated. This leaves the entry belonging to the object GOT with the num_pages count of 1 it was originally initialized with. Later on when GOTs are being merged in a multi-got link, this causes the value of entry->num_pages in add_got_page_entries to always be 1 and underestimates the number of pages required for the new entry. This in turn leads to an assertion failure in get_got_page_offset where we run out of pages. Fix by obtaining the object's GOT entry unconditionally and not just the first time it gets created. Now that entry2 is always valid, remove the useless NULL checks. gold/ PR gold/22770 * mips.cc (Mips_got_info::record_got_page_entry): Fetch existing page entries for the object's GOT.
