2620 generic_link_add_symbols.
2621 (_bfd_generic_link_add_symbols_collect): New function, like
2622 _bfd_generic_link_add_symbols but also collect constructors and
2623 destructors by name as collect2 does.
2624 (generic_link_add_symbols): New function, like old
2625 _bfd_generic_link_add_symbols but with collect argument.
2626 (generic_link_add_object_symbols): Take collect argument.

2638 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2639 for first character in an extended name.
2640 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2641 "//" as the name of the special archive member holding the
2642 extended name table.
2644 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2646 Support for link_order types which generate relocs in order to
2647 support -Ur in the linker.
2648 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2649 from call to _bfd_generic_link_add_one_symbol.
2650 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2651 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2652 instead of bitsize to add_to_set call back.
2653 (_bfd_generic_final_link): Account for link_order relocs when
2654 allocating space for relocations. Handle them in link_order loop.
2655 (_bfd_generic_reloc_link_order): New function.

2660 argument from declaration.
2661 (_bfd_generic_reloc_link_order): Declare.
2662 (_bfd_count_link_order_relocs): Declare.

2671 call to _bfd_generic_link_add_one_symbol.
2672 (ecoff_bfd_final_link): Account for link_order relocs when
2673 allocating space for relocations. Handle them in link_order loop.
2674 (ecoff_link_write_external): Set the storage class of a defined
2675 linker created symbol based on the section it is in. Correct
2676 bfd_link_hash_weak case to use .sc rather than .st.
2677 (ecoff_reloc_link_order): New function.
2678 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2680 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2689 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2691 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2693 * som.c (bfd_section_from_som_symbol): Only to do the value
2694 comparison for function symbols within executables.
2696 * som.c (bfd_section_from_som_symbol): Renamed from
2697 som_section_from_subspace_index. Pass in a native SOM symbol.
2698 For executables, iterate through the sections to find out
2699 which contains the symbol's address rather than using the
2700 symbol_info field. (symbol_info has a different meaning for
2701 dynamicly linked executables.)
2703 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2706 * som.c (som_begin_writing): Fix braino (one call to align
2707 space/subspace data was done unconditionally rather than
2708 just for executables.)
2710 * som.c (som_begin_writing): Align text in all executables to
2711 make HPUX kernel happy. Fixes strip/objcopy for shared
2714 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2716 * som.c (som_begin_writing): Account for alignment needs of
2717 subspaces too when writing executables. Never request a negative
2718 bss size. Fixes some problems with demand paged executables,
2719 still having problems with pure executables and shared executables.
2721 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2723 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2724 bfd_zalloc for rawptr, because later on we may call free, not
2727 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2728 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2729 * cisco-core.c: New file.
2730 * Makefile.in: Change accordingly.
2731 * configure.in: Recognize cisco_core_vec.
2732 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2733 * targets.c: Add cisco_core_vec.
2734 * bfd-in2.h: Rebuilt.
2736 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2738 * som.h (som_copyable_section_data_struct): New structure
2739 containing all the private section information which needs
2740 to be copied from input section to output section during
2742 (som_section_data_struct): Remove several fields now in
2743 som_copyable_section_data_struct. Make the space and
2744 subspace dictionaries be pointers (to save space when
2745 only reading objects).
2747 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2748 some references changed. Allocate a copyable data stucture if
2749 none exists. Store info into the copyable data structure.
2750 (bfd_som_set_subsection_attributes): Likewise.
2751 (som_is_space, som_is_subspace, som_is_container): New functions.
2752 Use these instead of directly accessing private data.
2753 (som_prep_headers): Allocate space and subspace headers here.
2754 Fill in some fields in the space/subspace headers from the
2756 (som_bfd_copy_private_section_data): Only copy the stuff
2757 that we really need to make objcopy and strip work. Allocate
2758 the copy_data structure for the output bfd before copying.
2760 * som.h (struct som_exec_data): New structure to hold exec
2761 info that must be preserved when running objcopy/strip.
2762 (struct somdata): Add new "exec_data" field and accessor
2763 macro. Add some comments on how the various fields are used.
2764 (som_section_data_struct): Make is_space and is_subspace bitfields.
2765 Delete unused subspace_index. All references now use the
2766 target_index field within the section structure itself.
2768 * som.c (make_unique_section): Delete unused declaration.
2769 (som_bfd_copy_private_bfd_data): New function.
2770 (som_object_setup): Allocate space for and save exec information
2771 that needs to be copied during objcopy/strip.
2772 (som_mkobject): Do not allocate space for a file header here.
2773 It is not used when only reading SOM objects.
2774 (som_prep_headers): Allocate space for and attach a file header
2775 to the output bfd. For executables, use the saved system_id
2776 value rather than trying to guess the right value. Do not abort
2777 wwhen setting file_hdr->entry* for executables.
2778 (som_begin_writing): For executables, set the exec_entry and
2780 (som_copy_private_backend_section_data): Always return a value.
2782 * libhppa.h (PA_PAGESIZE): Define.
2784 * som.c (SOM_ALIGN): Define.
2785 (som_begin_writing): If writing an executable, initialize all
2786 fields in the exec header to zero. Update fields in the exec
2787 header as sizes of loadable subspaces are computed. Carefully
2788 preserve alignments when building executables. Actually write the
2789 exec after all the fields are filled in.
2791 * Better long-filename handling. Reads SOM ABI compliant extended
2792 names, but doesn't quite write compliant extended names yet.
2793 * som.c (som_slurp_extended_name_table): Delete function. The
2794 generic code will handle things correctly.
2795 (som_slurp_armap): Seek to the beginning of the next member.
2796 (normalize): New function.
2797 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2798 name table into account when computing the file offsets in the
2799 SOM dictionary. Make sure to align to an even boundary.
2800 (som_write_armap): Initialize the checksum to zero.
2801 (ar_maxchars): Fix. Opps.
2803 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2805 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2806 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2808 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2810 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2811 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2812 * bfd-in2.h: Regenerated.
2814 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2815 this was also named trad_unix_bfd_copy_private_bfd_data.
2817 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2819 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2820 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2821 returns NULL, it is not an error. It's possible that some of
2822 these checks are not necessary (because the size can never be
2823 zero), but putting in the checks is the conservative thing to do
2824 in light of the fact that some of these malloc calls replaced
2825 unchecked alloca calls, in which a zero argument would work fine.
2827 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2829 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2830 duplicate definition.
2831 (osf_core_bfd_is_local_label): Define.
2833 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2834 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2835 failure indication, it merely means there are no relocs.
2837 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2838 after NAME, since SunOS /bin/cc can't handle it.
2840 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2842 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2843 From sukes@glue.umd.edu (Tasuki Hirata).
2845 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2847 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2848 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2849 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2851 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2853 * som.c (som_prep_for_fixups): Detect section symbols based
2854 on either the lack of private data or the symbol flags. Do not
2855 munge section symbol names anymore -- they no longer confuse GDB.
2856 (som_begin_writing): Leave space for an exec header if writing
2858 (som_slurp_symbol_table): Recognize both forms of section symbol
2859 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2860 section symbols to be the name of the section they represent.
2861 Debugging symbols begin with "L$0\001", not just "L$".
2863 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2865 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2867 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2868 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2869 and bfd_is_local_label.
2871 * targets.c: Add new entries to the bfd_target structure.
2873 * bfd.c (bfd_copy_private_bfd_data): New definition.
2875 * section.c (bfd_copy_private_section_data): New definition.

2883 * *-core.c: Provide default definitions for new functions in
2884 the target vector which all point to bfd_false.
2886 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2887 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2888 Default new vectors for copying private backend data to bfd_true.
2889 Default new vector for determining if a symbol is a local label
2890 to bfd_generic_is_local_label.
2892 * som.c (som_bfd_copy_private_section_data): New function.
2893 (som_bfd_is_local_label): New function.
2894 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2896 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2898 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2900 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2902 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2905 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2906 Indent some of them to GNU standards.
2908 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2909 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2910 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2911 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2912 Update copyright years.
2914 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2916 * som.c (som_prep_for_fixups): A relocation involving the section
2917 symbol for the *ABS* section is really a relocation involving
2919 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2920 undefined symbols. Correctly distinguish between debugger symbols
2921 and section symbols.
2923 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2924 for spaces and subspaces.
2926 * som.c (som_bfd_count_ar_symbols): Fix typo.
2928 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2929 HAS_RELOC based on the object's magic number.
2930 (make_unique_section): Delete function. BFD and its users are
2931 prepared to handle multiple sections with the same name.
2932 (setup_sections): Allocate space on the BFD's obstack to hold
2933 section names. Use bfd_make_setion_anyway rather than the
2934 obsolete make_unique_section.
2935 (som_prep_headers): Choose the correct SOM magic number based
2937 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2939 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2941 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2951 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2952 is always located at the start of the data section to allow
2953 recovery of the dynamic info from a stripped executable.
2954 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2957 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2959 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2960 cruft (like the #pragma alloca for AIX).
2961 In addition to that problem, the C alloca calls xmalloc, which
2962 means checking for being out of memory can't work right. The
2963 following changes remove all uses of alloca from BFD.
2964 * hosts/solaris2.h: Remove alloca cruft.
2965 * som.c: Replace alloca with a fixed size auto array.

2970 * linker.c: Replace alloca with obstack_alloc.
2971 * libbfd.h: Rebuilt.
2973 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2975 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2978 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2980 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2981 Elf*_Off typedefs by their expansion, the typedefs have been
2982 removed from include/elf/internal.h.
2983 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2984 SHT_PROGBITS section.
2986 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2988 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2992 * configure.host: Recognize i[34]86-sequent-*.
2994 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2995 return from bfd_seek indicates an error.
2996 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2997 TRAD_CORE_STACK_OFFSET.
2998 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2999 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3001 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3003 * som.[ch]: Do not include libhppa.h in som.c, instead include
3006 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3007 include it in elf32-hppa.h.
3009 * som.c (log2): Return -1 on error rather than aborting.
3010 (setup_sections): Bubble up an error from log2.
3012 * Changes to make HP C compiler happy in both traditional
3014 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3016 (bfd_som_set_section_attributes): Use unsigned int rather than
3017 unsigned char to avoid GNU-C extensions.
3018 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3019 or failure rather than aborting on failure.
3021 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3023 (bfd_som_attach_aux_hdr): Add prototype.
3024 (hppa_som-gen_reloc_type): Likewise.
3026 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3027 (hppa_look_for_stubs_in_section): Do not return false on failure
3028 until rest of code is ready to handle it. Abort for now.
3030 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3032 * bfd-in2.h: Rebuilt.
3034 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

3313 (b_out_relax_section): If a section contains no relocations, don't
3314 bother processing them.
3315 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4018 The sparc (and possibly other?) NLM format requires a different
4019 way to write exports, so add a write_export field to the backend
4020 data (and set it to NULL for everything but the sparc).
