* elf.c (bfd_elf_set_group_contents): Assign sh_info for ld -r when the signature symbol is global. * elflink.c (elf_link_input_bfd): Ensure group signature symbol is output when ld -r. Set group sh_info when local. * linker.c (default_indirect_link_order): Handle group sections specially. ld/ * ldemul.c (ldemul_place_orphan): Add "name" param. * ldemul.h (ldemul_place_orphan): Update prototype. (struct ld_emulation_xfer_struct <place_orphan>): Likewise. * ldlang.c (lang_place_orphans): Generate unique section names here.. * emultempl/elf32.em (place_orphan): ..rather than here. Don't directly use an existing output section statement that has no bfd section. * emultempl/pe.em (place_orphan): Likewise. * emultempl/pep.em (place_orphan): Likewise. * emultempl/beos.em (place_orphan): Adjust. * emultempl/spuelf.em (spu_place_special_section): Adjust place_orphan call. * emultempl/genelf.em (gld${EMULATION_NAME}_after_open): New function. (LDEMUL_AFTER_OPEN): Define.
