* 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.

(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...

(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. (fold_unary): Likewise.
