constify elfNN_bed
elfNN_bed was made writable as an expedient means of communicating
ld -z max-page-size and ld -z common-page-size values to BFD linker
code, and even for objcopy to communicate segment alignment between
copy_private_bfd_data, rewrite_elf_program_header and
assign_file_positions_for_load_sections. Some time later elfNN_bed
elf_osabi was written by gas. It turns out none of these
modifications to elfNN_bed was necessary, so make it const again.
include/
* bfdlink.h (struct bfd_link_info): Add maxpagesize and
commonpagesize.
bfd/
* elfxx-target.h (elfNN_bed): Constify.
* bfd.c (bfd_elf_set_pagesize): Delete.
(bfd_emul_set_maxpagesize, bfd_emul_set_commonpagesize): Delete.
* elf.c (get_program_header_size): Get commonpagesize from
link info.
(_bfd_elf_map_sections_to_segments): Get maxpagesize from link info.
(assign_file_positions_for_load_sections): Likewise.
(assign_file_positions_for_non_load_sections): Likewise.
(rewrite_elf_program_header): Add maxpagesize param. Set map_p_align.
(copy_private_bfd_data): Don't call bfd_elf_set_maxpagesize.
Instead pass maxpagesize to rewrite_elf_program_header.
* elf32-nds32.c (relax_range_measurement): Add link_info param.
Get maxpagesize from link_info. Adjust caller.
* bfd-in2.h: Regenerate.
gas/
* config/obj-elf.c (obj_elf_section): Don't set elf_osabi here.
(obj_elf_type): Likewise.
ld/
* ld.h (ld_config_type): Delete maxpagesize and commonpagesize.
* emultempl/elf.em: Use link_info rather than config
for maxpagesize and commonpagesize.
* emultempl/ppc32elf.em: Likewise.
* ldexp.c (fold_binary, fold_name): Likewise.
* ldemul.c (after_parse_default): Likewise.
(set_output_arch_default): Don't call bfd_emul_set_maxpagesize
or bfd_emul_set_commonpagesize.
