* elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL* relocs in shared libraries which refer to local symbols. Cope with addend when processing a GOT relocation. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols for sections that the linker didn't create. (ppc_elf_finish_dynamic_sections): Only try to write out a section symbol if it was created in ppc_elf_size_dynamic_sections. (ppc_elf_relocate_section): Complain if we have to generate a reloc relative to a section for which we didn't output a symbol. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up. PLT relocs are 'rela' relocs, like everything else. .rela.plt is not a read-only section, so we don't have to special-case it. * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Entries in the .rela.bss section are (of course) 'rela' relocs not 'rel' relocs. * elf32-ppc.c (ppc_elf_check_relocs): Initialise srelgot. (ppc_elf_relocate_section): @got offsets are 4 from start of the actual .got section. * elflink.c (_bfd_elf_create_got_section): The three reserved words start from the symbol '_GLOBAL_OFFSET_TABLE_'. * elf32-ppc.c (ppc_elf_size_dynamic_sections): '.rela' is 5 characters, not 4. * elf32-ppc.c (ppc_elf_check_relocs): Use _bfd_elf_create_got_section to create the GOT rather than ppc_elf_create_linker_section. Create the '.rela.got' section ourselves. (ppc_elf_finish_dynamic_symbol): Set up GOT relocations when a symbol has a GOT entry. (ppc_elf_relocate_section): Record when a symbol is used through the GOT, and allocate space in the GOT for each such symbol. (ppc_elf_adjust_dynamic_symbol): Delete unused .got.plt stuff. (ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT stuff. * elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be treated in a similar way to ADDR16_HA relocs. (ppc_elf_relocate_section): PLTREL24 relocs do not get copied into shared objects; the linker must deal with them. (ppc_elf_create_linker_section): Stop setting _GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused LINKER_SECTION_PLT stuff. (ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff. (ppc_elf_finish_dynamic_sections): Use BFD calls to get GOT section, not ELF-specific calls. (elf_backend_plt_not_loaded): Set to 1. (elf_backend_got_symbol_offset): Set to 4. * elf-bfd.h (elf_backend_data): Add 'plt_not_loaded' member for when ld.so fills in the PLT; and 'got_symbol_offset' member. * elflink.c (_bfd_elf_create_dynamic_sections): Apply plt_not_loaded member. (_bfd_elf_create_got_section): Apply got_symbol_offset. * elfxx-target.h (elf_backend_plt_not_loaded): Set default to 'loaded'. (elf_backend_G_O_T_offset): Set default to 0. (elfNN_bed): Set added fields. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting DT_RELENT in shared objects; should be DT_RELAENT. * elf32-ppc.c (ppc_elf_relocate_section): Propagate R_PPC_ADDR16_HA relocs to shared objects. Cope with case where such a reloc (in a non-shared object) refers to a symbol that's not defined.
