Skip an archive element if not added by linker
During archive rescan to resolve symbol references for files added by LTO, linker add_archive_element callback is called to check if an archive element should added. After all IR symbols have been claimed, linker won't claim new IR symbols and shouldn't add the LTO archive element. This patch updates linker add_archive_element callback to return FALSE when seeing an LTO archive element during rescan and changes ELF linker to skip such archive element. bfd/ PR ld/20103 * cofflink.c (coff_link_check_archive_element): Return TRUE if linker add_archive_element callback returns FALSE. * ecoff.c (ecoff_link_check_archive_element): Likewise. * elf64-ia64-vms.c (elf64_vms_link_add_archive_symbols): Skip archive element if linker add_archive_element callback returns FALSE. * elflink.c (elf_link_add_archive_symbols): Likewise. * pdp11.c (aout_link_check_ar_symbols): Likewise. * vms-alpha.c (alpha_vms_link_add_archive_symbols): Likewise. * xcofflink.c (xcoff_link_check_dynamic_ar_symbols): Likewise.
