Ken Raeburn	b818a3257f	fix some compilation warnings from sun cc	32 years ago
Ken Raeburn	ede4eed483	Added new files elflink.c, elflink.h, elfcore.h. Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data structure to elfcode.h with some misc data and callback functions. Added a pointer to that structure to the target back end data. More work can be done here. Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or _bfd_elf. Updated most call sites, sometimes defined some macros. Moved some dynamic linking support code from m68k, sparc, i386 to common files, using target back end flags to control behavior. More work can probably be done here too. Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h, elflink.h, or elflink.c. Now elfcode.h contains only .o and executable support, plus #includes of elfcore.h and elflink.h. Much of the contents of these other header files can probably still be moved from the .h files to the .c files, to get compiled only once. Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized variables, in generic and cpu-specific code.	32 years ago

Ian Lance Taylor	e4a4da62ab	* elfcode.h (elf_map_symbols): Don't worry about section symbols in a section not owned by any BFD. (elf_section_from_bfd_section): Separate out loop which calls backend routine. Check bfd_section and call the backend routine even for a section not owned by any BFD. * elf32-mips.c (mips_elf_section_from_bfd_section): Handle .acommon section.	32 years ago
Ian Lance Taylor	eb4267a3f9	Use a hash table when writing out ELF symbol names. * elfcode.h (elf_stringtab_init): New static function. (bfd_new_strtab, bfd_add_to_strtab, bfd_add_2_to_strtab): Remove. Change all callers to use elf_stringtab_init or _bfd_stringtab_add, and get stringtab lengths using _bfd_stringtab_size. (elf_fake_sections): Change ignored argument to pointer to boolean, and set the boolean to true if an error occurs. If an error has already occurred, don't do anything. (assign_section_numbers): Just set sh_size, not contents. (elf_compute_section_file_positions): Pass the address of a boolean to elf_fake_sections. Pass the address of a bfd_strtab_hash to swap_out_syms. Write out the .strtab section. (prep_headers): Change shstrtab to bfd_strtab_hash. (swap_out_syms): Take a pointer to a bfd_strtab_hash as an argument. Set it to the symbol names. (NAME(bfd_elf,write_object_contents)): Write out the section header names using _bfd_stringtab_emit. (elf_debug_section): Remove first argument; get the section name via the bfd_section pointer. Change caller. (elf_bfd_final_link): Write out the symbol names using _bfd_stringtab_emit. Likewise for the .dynstr section contents. Free the symbol names at the end of the function. (elf_link_input_bfd): Remove the last argument, output_names, from relocate_section. Save the old symbol contents before calling elf_link_output_sym, and restore them afterward. * libelf.h (struct elf_link_hash_table): Change dynstr field to struct bfd_strtab_hash. (struct elf_backend_data): Remove last argument, output_names, from elf_backend_relocate_section field. (struct strtab): Don't define. (struct elf_obj_tdata): Change strtab_ptr field to struct bfd_strtab_hash. * elf32-hppa.c (elf32_hppa_relocate_section): Remove last argument, output_names. * elf32-i386.c (elf_i386_relocate_section): Likewise. * elf32-mips.c (mips_elf_relocate_section): Likewise. * elf32-sparc.c (elf32_sparc_relocate_section): Likewise.	32 years ago
Ian Lance Taylor	24f13b0331	* elfcode.h (elf_swap_shdr_in): Use rawdata, not bfd_section. Clear contents field. (bfd_section_from_shdr): In SHT_STRTAB case, check bfd_section, not rawdata. Don't set rawdata if e_shstrndx. Use bfd_section rather than rawdata in commented out code. In SHT_REL[A] case, don't bother to check elf_section_data of section returned by section_from_elf_index. (elf_fake_sections): Set bfd_section, not rawdata. Don't set size. (elf_map_symbols): Don't set elf_num_section_syms. Don't create section symbols that already exist. (assign_file_position_for_section): Use bfd_section, not rawdata. (section_from_elf_index): Just check bfd_section field. (elf_section_from_bfd_section): Likewise. (elf_debug_section): Don't print rawdata, contents, or size. (elf_link_add_object_symbols): Don't error out if section_from_elf_index returns NULL. (elf_bfd_final_link): Check return value from section_from_elf_index against NULL, not bfd_is_abs_section. (elf_link_input_bfd): Don't check section_from_elf_index return value. * libelf.h (struct elf_obj_tdata): Remove num_section_syms field. (elf_num_section_syms): Don't define. * elf.c (elf_get_str_section): Store section contents in contents field rather than rawdata field. (elf_string_from_elf_section): Likewise. (_bfd_elf_make_section_from_shdr): Store BFD section pointer in bfd_section field rather than rawdata field. * elf32-hppa.c (elf32_hppa_read_symext_info): Use bfd_section rather than rawdata. (elf32_hppa_size_stubs): Likewise. * elf32-mips.c (mips_elf_final_write_processing): Use bfd_section rathern than rawdata. (mips_elf_section_from_shdr): Likewise. (mips_elf_section_processing): Likewise. (mips_elf_section_from_bfd_section): Remove rawdata check.	32 years ago
