444 declaration to take boolean * rather than asymbol list.
445 (bfd_perform_slip): Change declaration to take BFD rather than
447 * coff-h8300.c (h300_reloc16_estimate): Take BFD argument rather
448 than asymbol list. Changed calls to bfd_perform_slip.
449 * bfd-in2.h: Rebuilt.

454 * genlink.h (_bfd_generic_link_get_symbols): Define.
455 (_bfd_generic_link_get_symcount): Define.
456 * linker.c (generic_link_read_symbols): New function.

476 relocs when allocating space for relocations. Set SEC_RELOC flag
477 for any section which has relocs. Handle link_order relocs in
478 link_order loop. Use _bfd_generic_link_add_symbols_collect for
479 add_symbls entry point.
481 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
482 counting relocs. Set SEC_RELOC flag for any section which has

504 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
506 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
507 for first character in an extended name.
508 (_bfd_write_archive_contents): If ar_padchar == '/', then use
509 "//" as the name of the special archive member holding the
512 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
514 Support for link_order types which generate relocs in order to
515 support -Ur in the linker.
516 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
517 from call to _bfd_generic_link_add_one_symbol.
518 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
519 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
520 instead of bitsize to add_to_set call back.
521 (_bfd_generic_final_link): Account for link_order relocs when
522 allocating space for relocations. Handle them in link_order loop.
523 (_bfd_generic_reloc_link_order): New function.
524 (_bfd_default_link_order): If a reloc_link_order is seen here,
526 (_bfd_count_link_order_relocs): New function.

533 call to _bfd_generic_link_add_one_symbol.
534 (NAME(aout,final_link)): Account for link_order relocs when
535 allocating space for relocations. Handle them after handling all
537 (aout_link_reloc_link_order): New function.
538 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
539 call to _bfd_generic_link_add_one_symbol.

554 bfd_zmalloc. Free a pointer, not a union.
555 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
557 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
559 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
561 * som.c (bfd_section_from_som_symbol): Only to do the value
562 comparison for function symbols within executables.
564 * som.c (bfd_section_from_som_symbol): Renamed from
565 som_section_from_subspace_index. Pass in a native SOM symbol.
566 For executables, iterate through the sections to find out
567 which contains the symbol's address rather than using the
568 symbol_info field. (symbol_info has a different meaning for
569 dynamicly linked executables.)
571 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
574 * som.c (som_begin_writing): Fix braino (one call to align
575 space/subspace data was done unconditionally rather than
576 just for executables.)
578 * som.c (som_begin_writing): Align text in all executables to
579 make HPUX kernel happy. Fixes strip/objcopy for shared
582 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
584 * som.c (som_begin_writing): Account for alignment needs of
585 subspaces too when writing executables. Never request a negative
586 bss size. Fixes some problems with demand paged executables,
587 still having problems with pure executables and shared executables.
589 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
591 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
592 bfd_zalloc for rawptr, because later on we may call free, not
595 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
596 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
597 * cisco-core.c: New file.

602 * bfd-in2.h: Rebuilt.
604 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
606 * som.h (som_copyable_section_data_struct): New structure
607 containing all the private section information which needs
608 to be copied from input section to output section during
610 (som_section_data_struct): Remove several fields now in
611 som_copyable_section_data_struct. Make the space and
612 subspace dictionaries be pointers (to save space when
613 only reading objects).
615 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
616 some references changed. Allocate a copyable data stucture if
617 none exists. Store info into the copyable data structure.
618 (bfd_som_set_subsection_attributes): Likewise.
619 (som_is_space, som_is_subspace, som_is_container): New functions.
620 Use these instead of directly accessing private data.
621 (som_prep_headers): Allocate space and subspace headers here.
622 Fill in some fields in the space/subspace headers from the
624 (som_bfd_copy_private_section_data): Only copy the stuff
625 that we really need to make objcopy and strip work. Allocate
626 the copy_data structure for the output bfd before copying.
628 * som.h (struct som_exec_data): New structure to hold exec
629 info that must be preserved when running objcopy/strip.
630 (struct somdata): Add new "exec_data" field and accessor
631 macro. Add some comments on how the various fields are used.
632 (som_section_data_struct): Make is_space and is_subspace bitfields.
633 Delete unused subspace_index. All references now use the
634 target_index field within the section structure itself.
636 * som.c (make_unique_section): Delete unused declaration.
637 (som_bfd_copy_private_bfd_data): New function.
638 (som_object_setup): Allocate space for and save exec information
639 that needs to be copied during objcopy/strip.
640 (som_mkobject): Do not allocate space for a file header here.
641 It is not used when only reading SOM objects.
642 (som_prep_headers): Allocate space for and attach a file header
643 to the output bfd. For executables, use the saved system_id
644 value rather than trying to guess the right value. Do not abort
645 wwhen setting file_hdr->entry* for executables.
646 (som_begin_writing): For executables, set the exec_entry and
648 (som_copy_private_backend_section_data): Always return a value.
650 * libhppa.h (PA_PAGESIZE): Define.
652 * som.c (SOM_ALIGN): Define.
653 (som_begin_writing): If writing an executable, initialize all
654 fields in the exec header to zero. Update fields in the exec
655 header as sizes of loadable subspaces are computed. Carefully
656 preserve alignments when building executables. Actually write the
657 exec after all the fields are filled in.
659 * Better long-filename handling. Reads SOM ABI compliant extended
660 names, but doesn't quite write compliant extended names yet.
661 * som.c (som_slurp_extended_name_table): Delete function. The
662 generic code will handle things correctly.
663 (som_slurp_armap): Seek to the beginning of the next member.
664 (normalize): New function.
665 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
666 name table into account when computing the file offsets in the
667 SOM dictionary. Make sure to align to an even boundary.
668 (som_write_armap): Initialize the checksum to zero.
669 (ar_maxchars): Fix. Opps.
671 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
673 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
674 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
676 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
678 * bfd-in.h (BFD_VERSION): Use @VERSION@.
679 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
680 * bfd-in2.h: Regenerated.
682 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
683 this was also named trad_unix_bfd_copy_private_bfd_data.
685 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
687 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
688 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
689 returns NULL, it is not an error. It's possible that some of
690 these checks are not necessary (because the size can never be
691 zero), but putting in the checks is the conservative thing to do
692 in light of the fact that some of these malloc calls replaced
693 unchecked alloca calls, in which a zero argument would work fine.
695 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
697 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
698 duplicate definition.
699 (osf_core_bfd_is_local_label): Define.
701 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
702 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
703 failure indication, it merely means there are no relocs.
705 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
706 after NAME, since SunOS /bin/cc can't handle it.
708 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
710 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
711 From sukes@glue.umd.edu (Tasuki Hirata).
713 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
715 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
716 all that convoluted stuff with NAME, CAT3, etc. The convoluted
717 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
719 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
721 * som.c (som_prep_for_fixups): Detect section symbols based
722 on either the lack of private data or the symbol flags. Do not
723 munge section symbol names anymore -- they no longer confuse GDB.
724 (som_begin_writing): Leave space for an exec header if writing
726 (som_slurp_symbol_table): Recognize both forms of section symbol
727 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
728 section symbols to be the name of the section they represent.
729 Debugging symbols begin with "L$0\001", not just "L$".
731 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
733 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
735 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
736 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
737 and bfd_is_local_label.
739 * targets.c: Add new entries to the bfd_target structure.
741 * bfd.c (bfd_copy_private_bfd_data): New definition.

749 * libbfd.c (bfd_generic_is_local_label): New function.
751 * *-core.c: Provide default definitions for new functions in
752 the target vector which all point to bfd_false.
754 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
755 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
756 Default new vectors for copying private backend data to bfd_true.
757 Default new vector for determining if a symbol is a local label
758 to bfd_generic_is_local_label.
760 * som.c (som_bfd_copy_private_section_data): New function.
761 (som_bfd_is_local_label): New function.
762 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
764 * elf32-hppa.c (hppa_elf_is_local_label): New function.
766 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
768 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
770 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
773 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
774 Indent some of them to GNU standards.
776 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
777 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
778 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
779 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
780 Update copyright years.
782 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
784 * som.c (som_prep_for_fixups): A relocation involving the section
785 symbol for the *ABS* section is really a relocation involving
787 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
788 undefined symbols. Correctly distinguish between debugger symbols
791 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
792 for spaces and subspaces.
794 * som.c (som_bfd_count_ar_symbols): Fix typo.
796 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
797 HAS_RELOC based on the object's magic number.
798 (make_unique_section): Delete function. BFD and its users are
799 prepared to handle multiple sections with the same name.
800 (setup_sections): Allocate space on the BFD's obstack to hold
801 section names. Use bfd_make_setion_anyway rather than the
802 obsolete make_unique_section.
803 (som_prep_headers): Choose the correct SOM magic number based
805 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
807 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
809 * elf32-ppc.c: Renamed from elf32-powerpc.c.

819 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
821 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info

827 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
829 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
830 cruft (like the #pragma alloca for AIX).
831 In addition to that problem, the C alloca calls xmalloc, which
832 means checking for being out of memory can't work right. The
833 following changes remove all uses of alloca from BFD.
834 * hosts/solaris2.h: Remove alloca cruft.
835 * som.c: Replace alloca with a fixed size auto array.

848 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
850 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
851 Elf*_Off typedefs by their expansion, the typedefs have been
852 removed from include/elf/internal.h.
853 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
854 SHT_PROGBITS section.
856 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
858 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
860 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
862 * configure.host: Recognize i[34]86-sequent-*.
864 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
865 return from bfd_seek indicates an error.
866 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
867 TRAD_CORE_STACK_OFFSET.
868 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
869 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
871 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
873 * som.[ch]: Do not include libhppa.h in som.c, instead include
876 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
877 include it in elf32-hppa.h.
879 * som.c (log2): Return -1 on error rather than aborting.
880 (setup_sections): Bubble up an error from log2.
882 * Changes to make HP C compiler happy in both traditional
884 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
886 (bfd_som_set_section_attributes): Use unsigned int rather than
887 unsigned char to avoid GNU-C extensions.
888 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
889 or failure rather than aborting on failure.
891 * som.h (bfd_som_set_section_attributes): Fix prototype to match
893 (bfd_som_attach_aux_hdr): Add prototype.
894 (hppa_som-gen_reloc_type): Likewise.
896 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
897 (hppa_look_for_stubs_in_section): Do not return false on failure
898 until rest of code is ready to handle it. Abort for now.
900 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
902 * bfd-in2.h: Rebuilt.
904 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
906 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
907 * Makefile.in: delete an extra blank.
908 * configure.in : Add i396os9k_vec.

1891 The sparc (and possibly other?) NLM format requires a different
1892 way to write exports, so add a write_export field to the backend
1893 data (and set it to NULL for everything but the sparc).

3129 * From Pete Hoogenboom (hoogen@cs.utah.edu)
3130 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
3131 in last change. Always rebuild symbol extension section the first
3132 time though if output sections exist (fixes ld -r problems).

3150 * config.bfd: Use bigmips for mips*-*-bsd*.
3152 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3154 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
3155 Handle symbol number of zero.
3157 * reloc.c (enum bfd_reloc_code_real): Added
3158 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
3159 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
3160 * bfd-in2.h: Rebuilt.
3161 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
3162 BFD_RELOC_MIPS_LITERAL.
3163 * elf32-mips.c (mips_reloc_map): Handle new relocs.
3164 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
3167 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
3168 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
3169 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
3170 MY_bfd_seclet_link): Define.
3171 (MY_bfd_reloc_type_lookup): Rename from
3172 MY_reloc_howto_type_lookup.
3173 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
3174 (MY(vec)): Use JUMP_TABLE rather than listing functions.
3175 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
3176 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
3177 terms of MY, because that causes a recusive invocation of CAT when
3178 expanded within JUMP_TABLE, and ANSI compilers don't expand
3180 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
3181 MY_reloc_howto_type_lookup, and don't define in terms of MY.
3182 (MY_canonicalize_reloc): Don't define in terms of MY.
3183 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
3184 than listing functions.
