Set my_archive for thin archives
LTO plugin support in plugin_maybe_claim wants to close the IR bfd after replacing it with the recompiled object, but can't do so for archive elements due to various pointers that access the archive bfd. Thin archives have the same problem. They too cannot have their element bfds closed. PR ld/20241 bfd/ * archive.c (open_nested_file): Set my_archive. * bfd.c (_bfd_default_error_handler <%B>): Exclude archive file name for thin archives. * bfdio.c (bfd_tell): Don't adjust origin for thin archives. (bfd_seek): Likewise. * bfdwin.c (bfd_get_file_window): Likewise. * cache.c (cache_bmmap): Likewise. (bfd_cache_lookup_worker): Don't look in my_archive for thin archives. * mach-o.c (bfd_mach_o_follow_dsym): Don't open my_archive for thin archives. * plugin.c (try_claim): Likewise. * xcofflink.c (xcoff_link_add_dynamic_symbols): Use import path of file within thin archive, not the archive. binutils/ * bucomm.c (bfd_get_archive_filename): Return file name within thin archive. ld/ * ldmain.c (add_archive_element): Just print file name of file within thin archives. * ldmisc.c (vfinfo): Likewise. * plugin.c (plugin_object_p): Open file within thin archives. (plugin_maybe_claim): Expand comment.
