* elflink.c (elf_bfd_final_link): Don't output STT_SECTION symbol
into .dynsym if elf_section_data (sec)->dynindx <= 0.
Adjust counting of last_local.
(_bfd_elf_link_renumber_dynsyms): Don't assign dynindx to sections
other than SHT_PROGBITS/SHT_NOBITS and neither for .got/.got.plt/.plt
created by the linker nor !SHF_ALLOC.
* elf32-i386.c (elf_i386_finish_dynamic_sections): Point
DT_PLTGOT to the start of the .got.plt section instead of the
.got output section. Set sh_entsize for .got section in addition
to .got.plt.
(elf_i386_relocate_section): Don't assume _GLOBAL_OFFSET_TABLE_
is at sgot->output_section->vma.
* elf64-x86-64.c (elf64_x86_64_finish_dynamic_sections): Point
DT_PLTGOT to the start of the .got.plt section instead of the
.got output section.
(elf64_x86_64_relocate_section): Don't assume _GLOBAL_OFFSET_TABLE_
is at sgot->output_section->vma. Set sh_entsize for .got section
in addition to .got.plt.
* elf.c (_bfd_elf_print_private_bfd_data): Handle PT_GNU_RELRO.
(bfd_section_from_phdr): Likewise.
(map_sections_to_segments): Likewise.

* elflink.c (bfd_elf_size_dynamic_sections): Set
elf_tdata (output_bfd)->relro from info->relro.
* elf-bfd.h (struct elf_obj_tdata): Add relro field.
include/
* bfdlink.h (struct bfd_link_info): Add relro, relro_start and
relro_end fields.
* elf/common.h (PT_GNU_EH_FRAME, PT_GNU_STACK): Add comments.
(PT_GNU_RELRO): Define.
binutils/
* readelf.c (get_segment_type): Handle PT_GNU_RELRO.
ld/
* genscripts.sh: Generate -z combreloc -z now -z relro scripts
for binaries, -shared and -pie.
* emulparams/elf_i386.sh (SEPARATE_GOTPLT): Set.
* emulparams/elf_x86_64.sh (SEPARATE_GOTPLT): Set.
* emulparams/elf32ppc.sh (OTHER_READWRITE_SECTIONS): Rename to...
(OTHER_RELRO_SECTIONS): ... this.
* ldlex.l (DATA_SEGMENT_RELRO_END): Add.
* emultempl/elf32.em (gld${EMULATION_NAME}_handle_option): Handle
-z relro and -z norelro.
(gld${EMULATION_NAME}_list_options): Add it to usage.
(gld${EMULATION_NAME}_get_script): Return -z combreloc -z now
-z relro scripts when appropriate.
* scripttempl/elf.sc: Unset SEPARATE_GOTPLT if RELRO_NOW is set.
Create separate .got.plt section if SEPARATE_GOTPLT.
Move sections which are only written during relocation handling
to the beginning of RW segment. If NO_SMALL_DATA, move .got
before .data. Add DATA_SEGMENT_RELRO_END directive.
Include OTHER_RELRO_SECTIONS.
* ldgram.y (DATA_SEGMENT_RELRO_END): Add.
* ldexp.c (exp_print_token): Handle DATA_SEGMENT_RELRO_END.
