* elf-bfd.h (struct bfd_elf_section_data): Add "group" and

	"next_in_group".  Fix gp and gp_size comments.
	* elf.c (union elf_internal_group): New.
	(setup_group): New function.
	(_bfd_elf_make_section_from_shdr): Set BFD flags for SHT_GROUP.
	Call setup_group for SHF_GROUP sections.
	(bfd_section_from_shdr): Build a BFD section for SHT_GROUP.
	(elf_fake_sections): Set header type for SEC_GROUP, and header
	flags for sections in a group.
	(set_group_contents): New function.
	(_bfd_elf_compute_section_file_positions): Call it.
	(assign_section_numbers): Set sh_link for SHT_GROUP.
	* elflink.h (gc_mark_hook): Handle section groups.
	* elfxx-target.h: Add SEC_GROUP to applicable_flags.
	* section.c (SEC_GROUP): Define.
	(struct sec): Comment fixes.
	* bfd-in2.h: Regenerate.

	* elf.c (bfd_elf_print_symbol): Formatting fix; migrate expression
	out of function args.
	(_bfd_elf_canonicalize_reloc): Similarly.
	(_bfd_elf_get_symtab): Here too.
	(_bfd_elf_canonicalize_dynamic_symtab): And here.
	* elfcode.h (elf_slurp_symbol_table): Don't recalculate size for
	bfd_bread, and remove unnecessary cast.
