2586 in asymbol udata field.
2588 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2600 add_symbls entry point.
2602 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2603 counting relocs. Set SEC_RELOC flag for any section which has

2608 * linker.c (_bfd_generic_link_add_symbols): Just call
2609 generic_link_add_symbols.
2610 (_bfd_generic_link_add_symbols_collect): New function, like
2611 _bfd_generic_link_add_symbols but also collect constructors and
2612 destructors by name as collect2 does.
2613 (generic_link_add_symbols): New function, like old
2614 _bfd_generic_link_add_symbols but with collect argument.
2615 (generic_link_add_object_symbols): Take collect argument.

2627 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2628 for first character in an extended name.
2629 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2630 "//" as the name of the special archive member holding the
2631 extended name table.
2633 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2635 Support for link_order types which generate relocs in order to
2636 support -Ur in the linker.
2637 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2638 from call to _bfd_generic_link_add_one_symbol.
2639 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2640 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2641 instead of bitsize to add_to_set call back.
2642 (_bfd_generic_final_link): Account for link_order relocs when
2643 allocating space for relocations. Handle them in link_order loop.
2644 (_bfd_generic_reloc_link_order): New function.
2645 (_bfd_default_link_order): If a reloc_link_order is seen here,
2647 (_bfd_count_link_order_relocs): New function.
2648 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2649 argument from declaration.
2650 (_bfd_generic_reloc_link_order): Declare.
2651 (_bfd_count_link_order_relocs): Declare.
2652 * libbfd.h: Rebuilt.
2653 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2654 call to _bfd_generic_link_add_one_symbol.
2655 (NAME(aout,final_link)): Account for link_order relocs when

2660 call to _bfd_generic_link_add_one_symbol.
2661 (ecoff_bfd_final_link): Account for link_order relocs when
2662 allocating space for relocations. Handle them in link_order loop.
2663 (ecoff_link_write_external): Set the storage class of a defined
2664 linker created symbol based on the section it is in. Correct
2665 bfd_link_hash_weak case to use .sc rather than .st.
2666 (ecoff_reloc_link_order): New function.
2667 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2669 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2674 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2675 bfd_zmalloc. Free a pointer, not a union.
2676 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2678 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2680 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2682 * som.c (bfd_section_from_som_symbol): Only to do the value
2683 comparison for function symbols within executables.
2685 * som.c (bfd_section_from_som_symbol): Renamed from
2686 som_section_from_subspace_index. Pass in a native SOM symbol.
2687 For executables, iterate through the sections to find out
2688 which contains the symbol's address rather than using the
2689 symbol_info field. (symbol_info has a different meaning for
2690 dynamicly linked executables.)
2692 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2695 * som.c (som_begin_writing): Fix braino (one call to align
2696 space/subspace data was done unconditionally rather than
2697 just for executables.)
2699 * som.c (som_begin_writing): Align text in all executables to
2700 make HPUX kernel happy. Fixes strip/objcopy for shared
2703 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2705 * som.c (som_begin_writing): Account for alignment needs of
2706 subspaces too when writing executables. Never request a negative
2707 bss size. Fixes some problems with demand paged executables,
2708 still having problems with pure executables and shared executables.
2710 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2712 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2713 bfd_zalloc for rawptr, because later on we may call free, not
2716 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2717 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2718 * cisco-core.c: New file.
2719 * Makefile.in: Change accordingly.
2720 * configure.in: Recognize cisco_core_vec.
2721 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2722 * targets.c: Add cisco_core_vec.
2723 * bfd-in2.h: Rebuilt.
2725 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2727 * som.h (som_copyable_section_data_struct): New structure
2728 containing all the private section information which needs
2729 to be copied from input section to output section during
2731 (som_section_data_struct): Remove several fields now in
2732 som_copyable_section_data_struct. Make the space and
2733 subspace dictionaries be pointers (to save space when
2734 only reading objects).
2736 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2737 some references changed. Allocate a copyable data stucture if
2738 none exists. Store info into the copyable data structure.
2739 (bfd_som_set_subsection_attributes): Likewise.
2740 (som_is_space, som_is_subspace, som_is_container): New functions.
2741 Use these instead of directly accessing private data.
2742 (som_prep_headers): Allocate space and subspace headers here.
2743 Fill in some fields in the space/subspace headers from the
2745 (som_bfd_copy_private_section_data): Only copy the stuff
2746 that we really need to make objcopy and strip work. Allocate
2747 the copy_data structure for the output bfd before copying.
2749 * som.h (struct som_exec_data): New structure to hold exec
2750 info that must be preserved when running objcopy/strip.
2751 (struct somdata): Add new "exec_data" field and accessor
2752 macro. Add some comments on how the various fields are used.
2753 (som_section_data_struct): Make is_space and is_subspace bitfields.
2754 Delete unused subspace_index. All references now use the
2755 target_index field within the section structure itself.
2757 * som.c (make_unique_section): Delete unused declaration.
2758 (som_bfd_copy_private_bfd_data): New function.
2759 (som_object_setup): Allocate space for and save exec information
2760 that needs to be copied during objcopy/strip.
2761 (som_mkobject): Do not allocate space for a file header here.
2762 It is not used when only reading SOM objects.
2763 (som_prep_headers): Allocate space for and attach a file header
2764 to the output bfd. For executables, use the saved system_id
2765 value rather than trying to guess the right value. Do not abort
2766 wwhen setting file_hdr->entry* for executables.
2767 (som_begin_writing): For executables, set the exec_entry and
2769 (som_copy_private_backend_section_data): Always return a value.
2771 * libhppa.h (PA_PAGESIZE): Define.
2773 * som.c (SOM_ALIGN): Define.
2774 (som_begin_writing): If writing an executable, initialize all
2775 fields in the exec header to zero. Update fields in the exec
2776 header as sizes of loadable subspaces are computed. Carefully
2777 preserve alignments when building executables. Actually write the
2778 exec after all the fields are filled in.
2780 * Better long-filename handling. Reads SOM ABI compliant extended
2781 names, but doesn't quite write compliant extended names yet.
2782 * som.c (som_slurp_extended_name_table): Delete function. The
2783 generic code will handle things correctly.
2784 (som_slurp_armap): Seek to the beginning of the next member.
2785 (normalize): New function.
2786 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2787 name table into account when computing the file offsets in the
2788 SOM dictionary. Make sure to align to an even boundary.
2789 (som_write_armap): Initialize the checksum to zero.
2790 (ar_maxchars): Fix. Opps.
2792 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2794 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2795 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2797 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2799 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2800 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2801 * bfd-in2.h: Regenerated.
2803 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2804 this was also named trad_unix_bfd_copy_private_bfd_data.
2806 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2808 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2809 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2810 returns NULL, it is not an error. It's possible that some of
2811 these checks are not necessary (because the size can never be
2812 zero), but putting in the checks is the conservative thing to do
2813 in light of the fact that some of these malloc calls replaced
2814 unchecked alloca calls, in which a zero argument would work fine.
2816 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2818 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2819 duplicate definition.
2820 (osf_core_bfd_is_local_label): Define.
2822 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2823 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2824 failure indication, it merely means there are no relocs.
2826 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2827 after NAME, since SunOS /bin/cc can't handle it.
2829 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2831 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2832 From sukes@glue.umd.edu (Tasuki Hirata).
2834 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2836 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2837 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2838 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2840 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2842 * som.c (som_prep_for_fixups): Detect section symbols based
2843 on either the lack of private data or the symbol flags. Do not
2844 munge section symbol names anymore -- they no longer confuse GDB.
2845 (som_begin_writing): Leave space for an exec header if writing
2847 (som_slurp_symbol_table): Recognize both forms of section symbol
2848 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2849 section symbols to be the name of the section they represent.
2850 Debugging symbols begin with "L$0\001", not just "L$".
2852 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2854 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2856 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2857 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2858 and bfd_is_local_label.
2860 * targets.c: Add new entries to the bfd_target structure.
2862 * bfd.c (bfd_copy_private_bfd_data): New definition.
2864 * section.c (bfd_copy_private_section_data): New definition.
2866 * syms.c (bfd_is_local_label): New definition.
2868 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2870 * libbfd.c (bfd_generic_is_local_label): New function.
2872 * *-core.c: Provide default definitions for new functions in
2873 the target vector which all point to bfd_false.
2875 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2876 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2877 Default new vectors for copying private backend data to bfd_true.
2878 Default new vector for determining if a symbol is a local label
2879 to bfd_generic_is_local_label.
2881 * som.c (som_bfd_copy_private_section_data): New function.
2882 (som_bfd_is_local_label): New function.
2883 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2885 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2887 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2889 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2891 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2894 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2895 Indent some of them to GNU standards.
2897 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2898 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2899 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2900 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2901 Update copyright years.
2903 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2905 * som.c (som_prep_for_fixups): A relocation involving the section
2906 symbol for the *ABS* section is really a relocation involving
2908 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2909 undefined symbols. Correctly distinguish between debugger symbols
2910 and section symbols.
2912 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2913 for spaces and subspaces.
2915 * som.c (som_bfd_count_ar_symbols): Fix typo.
2917 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2918 HAS_RELOC based on the object's magic number.
2919 (make_unique_section): Delete function. BFD and its users are
2920 prepared to handle multiple sections with the same name.
2921 (setup_sections): Allocate space on the BFD's obstack to hold
2922 section names. Use bfd_make_setion_anyway rather than the
2923 obsolete make_unique_section.
2924 (som_prep_headers): Choose the correct SOM magic number based
2926 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2928 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2930 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2940 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2941 is always located at the start of the data section to allow
2942 recovery of the dynamic info from a stripped executable.
2943 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2946 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2948 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2949 cruft (like the #pragma alloca for AIX).
2950 In addition to that problem, the C alloca calls xmalloc, which
2951 means checking for being out of memory can't work right. The
2952 following changes remove all uses of alloca from BFD.
2953 * hosts/solaris2.h: Remove alloca cruft.
2954 * som.c: Replace alloca with a fixed size auto array.

2959 * linker.c: Replace alloca with obstack_alloc.
2960 * libbfd.h: Rebuilt.
2962 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2964 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2967 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2969 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2970 Elf*_Off typedefs by their expansion, the typedefs have been
2971 removed from include/elf/internal.h.
2972 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2973 SHT_PROGBITS section.
2975 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2977 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2981 * configure.host: Recognize i[34]86-sequent-*.
2983 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2984 return from bfd_seek indicates an error.
2985 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2986 TRAD_CORE_STACK_OFFSET.
2987 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2988 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2990 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2992 * som.[ch]: Do not include libhppa.h in som.c, instead include
2995 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2996 include it in elf32-hppa.h.
2998 * som.c (log2): Return -1 on error rather than aborting.
2999 (setup_sections): Bubble up an error from log2.
3001 * Changes to make HP C compiler happy in both traditional
3003 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3005 (bfd_som_set_section_attributes): Use unsigned int rather than
3006 unsigned char to avoid GNU-C extensions.
3007 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3008 or failure rather than aborting on failure.
3010 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3012 (bfd_som_attach_aux_hdr): Add prototype.
3013 (hppa_som-gen_reloc_type): Likewise.
3015 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3016 (hppa_look_for_stubs_in_section): Do not return false on failure
3017 until rest of code is ready to handle it. Abort for now.
3019 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3021 * bfd-in2.h: Rebuilt.
3023 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

3029 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
3031 * config.bfd : Add i386-os9k.
3032 * config/i386-os9k.mt : Newly add os9k target makefile.

3302 (b_out_relax_section): If a section contains no relocations, don't
3303 bother processing them.
3304 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4007 The sparc (and possibly other?) NLM format requires a different
4008 way to write exports, so add a write_export field to the backend
4009 data (and set it to NULL for everything but the sparc).

5294 expanded within JUMP_TABLE, and ANSI compilers don't expand
5296 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
5297 MY_reloc_howto_type_lookup, and don't define in terms of MY.
