more efficient backend code can be written for specific object files. Only existing efficient backend is a.out. * seclet.c, seclet.h: Removed. * hash.c, linker.c, genlink.h: New files. * bfd-in.h: Removed bfd_error_vector. Declared hash table structures and functions. (JUMP_TABLE): Removed bfd_seclet_link, added bfd_link_hash_table_create, bfd_link_add_symbols and bfd_final_link. * All backends: Changed accordingly. * bfd-in2.h: Rebuilt. * bfd.c (struct _bfd): Added link_next and archive_pass fields. Removed ld_symbols field. (bfd_nonrepresentable_section, bfd_undefined_symbol, bfd_reloc_value_truncated, bfd_reloc_is_dangerous, bfd_error_vector): Removed. (bfd_default_error_trap, bfd_error_trap, bfd_error_nonrepresentabltrap): Removed. (bfd_get_relocated_section_contents): Pass link_info. Pass link_order instead of seclet. Pass symbols. (bfd_relax_section): Pass link_info. (bfd_seclet_link): Removed. (bfd_link_hash_table_create, bfd_link_add_symbols, bfd_final_link): New macros. * libbfd-in.h: If __GNUC__ is defined and alloca is not, define alloca as __builtin_alloca. Declare internal linking functions. * libbfd.h: Rebuilt. * libbfd.c (bfd_seek): Comment out fseek assertion. It's worked for months. * reloc.c (reloc_howto_type): Added error_message argument to special_function field. Changed all callers and all definitions. (bfd_get_reloc_size): Make argument a const pointer. (bfd_perform_relocation): Add error_message argument to hold string set if return value if bfd_reloc_dangerous. Changed all callers. (_bfd_final_link_relocate, _bfd_relocate_contents): New functions. * section.c (asection): Renamed seclets_head and seclets_tail to link_order_head and link_order_tail. * targets.c (bfd_target): Replaced seclet argument with link_info and link_order and symbols arguments in bfd_get_relocated_section_contents. Added symbols argument to bfd_relax_section. Removed bfd_seclet_link. Added bfd_link_hash_table_create, bfd_link_add_symbols and bfd_final_link. * libaout.h (struct aoutdata): Added external_syms, external_sym_count, external_strings, sym_hashes fields. (obj_aout_external_syms, obj_aout_external_sym_count, obj_aout_external_strings, obj_aout_sym_hashes): New accessor macros. (WRITE_HEADERS): Only output symbols if outsymbols is not NULL. * aoutx.h: Wrote new back end linker routines. (translate_to_native_sym_flags): Return boolean value. Don't use bfd_error_vector. (NAME(aout,write_syms)): Return boolean value. Check return value of translate_to_native_sym_flags and bfd_write. * aout-target.h (final_link_callback): New function. (MY_bfd_final_link): New function. * aout-adobe.c (aout_adobe_write_object_contents): Check return value of aout_32_write_syms. * hp300hpux.c (MY(write_object_contents)): Likewise. * i386lynx.c (WRITE_HEADERS): Likewise. * libaout.h (WRITE_HEADERS): Likewise. * bout.c: Changed functions to use link_info->callbacks rather than bfd_error_vector, and link_orders rather than seclets. * coff-alpha.c: Likewise. * coff-h8300.c: Likewise. * coff-h8500.c: Likewise. * coff-sh.c: Likewise. * coff-z8k.c: Likewise. * elf32-hppa.c: Likewise. * reloc16.c: Likewise. * coff-alpha.c (alpha_ecoff_get_relocated_section_contents): Look up _gp in the hash table rather than in outsymbols. * coff-a29k.c (a29k_reloc): Pass errors back in new error_message argument rather than printing them. * coffcode.h (bfd_coff_reloc16_extra_cases): Take link_info and link_order arguments rather than seclet. Changed all uses and definitions. (bfd_coff_reloc16_estimate): Pass link_info arguments. Changed all uses and definitions. * libcoff.h: Rebuilt. * ecoff.c (ecoff_get_extr): If symbol is defined by linker, but not by ECOFF, make it scAbs. (ecoff_bfd_final_link): Renamed from ecoff_bfd_seclet_link and rewritten. * elf32-mips.c (mips_elf_final_link): Renamed from mips_elf_seclet_link and rewritten. * elf32-hppa.c (elf32_hppa_stub_description): Added link_info field. (new_stub, add_stub_by_name, hppa_elf_build_arg_reloc_stub, hppa_elf_build_long_branch_stub, hppa_look_for_stubs_in_section): Added link_info arguments. Changed all callers. * elfcode.h (elf_slurp_symbol_table): Don't quit if outsymbols is not NULL. * oasys.c (oasys_write_sections): Return boolean value rather than using bfd_error_vector. (oasys_write_object_contents): Check return value of oasys_write_sections. * hosts/std-host.h: Don't declare qsort or strtol. * Makefile.in: Rebuild dependencies. (BFD_LIBS): Removed seclet.o. Added hash.o and linker.o. (CFILES): Removed seclet.c. Added hash.c and linker.c. (HFILES): Removed seclet.h. Added genlink.h.
