2583 (_bfd_generic_link_add_symbols_collect): New function, like
2584 _bfd_generic_link_add_symbols but also collect constructors and
2585 destructors by name as collect2 does.
2586 (generic_link_add_symbols): New function, like old
2587 _bfd_generic_link_add_symbols but with collect argument.
2588 (generic_link_add_object_symbols): Take collect argument.

2596 * libbfd.h: Rebuilt.
2598 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2600 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2601 for first character in an extended name.
2602 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2603 "//" as the name of the special archive member holding the
2604 extended name table.
2606 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2608 Support for link_order types which generate relocs in order to
2609 support -Ur in the linker.
2610 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2611 from call to _bfd_generic_link_add_one_symbol.
2612 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2613 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2614 instead of bitsize to add_to_set call back.
2615 (_bfd_generic_final_link): Account for link_order relocs when
2616 allocating space for relocations. Handle them in link_order loop.
2617 (_bfd_generic_reloc_link_order): New function.
2618 (_bfd_default_link_order): If a reloc_link_order is seen here,
2620 (_bfd_count_link_order_relocs): New function.
2621 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2622 argument from declaration.
2623 (_bfd_generic_reloc_link_order): Declare.
2624 (_bfd_count_link_order_relocs): Declare.
2625 * libbfd.h: Rebuilt.
2626 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2627 call to _bfd_generic_link_add_one_symbol.
2628 (NAME(aout,final_link)): Account for link_order relocs when

2631 (aout_link_reloc_link_order): New function.
2632 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
2633 call to _bfd_generic_link_add_one_symbol.
2634 (ecoff_bfd_final_link): Account for link_order relocs when
2635 allocating space for relocations. Handle them in link_order loop.
2636 (ecoff_link_write_external): Set the storage class of a defined
2637 linker created symbol based on the section it is in. Correct
2638 bfd_link_hash_weak case to use .sc rather than .st.
2639 (ecoff_reloc_link_order): New function.
2640 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2642 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2644 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2647 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2648 bfd_zmalloc. Free a pointer, not a union.
2649 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2651 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2653 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2655 * som.c (bfd_section_from_som_symbol): Only to do the value
2656 comparison for function symbols within executables.
2658 * som.c (bfd_section_from_som_symbol): Renamed from
2659 som_section_from_subspace_index. Pass in a native SOM symbol.
2660 For executables, iterate through the sections to find out
2661 which contains the symbol's address rather than using the
2662 symbol_info field. (symbol_info has a different meaning for
2663 dynamicly linked executables.)
2665 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2668 * som.c (som_begin_writing): Fix braino (one call to align
2669 space/subspace data was done unconditionally rather than
2670 just for executables.)
2672 * som.c (som_begin_writing): Align text in all executables to
2673 make HPUX kernel happy. Fixes strip/objcopy for shared
2676 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2678 * som.c (som_begin_writing): Account for alignment needs of
2679 subspaces too when writing executables. Never request a negative
2680 bss size. Fixes some problems with demand paged executables,
2681 still having problems with pure executables and shared executables.
2683 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2685 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2686 bfd_zalloc for rawptr, because later on we may call free, not
2689 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2690 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2691 * cisco-core.c: New file.
2692 * Makefile.in: Change accordingly.
2693 * configure.in: Recognize cisco_core_vec.
2694 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2695 * targets.c: Add cisco_core_vec.
2696 * bfd-in2.h: Rebuilt.
2698 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2700 * som.h (som_copyable_section_data_struct): New structure
2701 containing all the private section information which needs
2702 to be copied from input section to output section during
2704 (som_section_data_struct): Remove several fields now in
2705 som_copyable_section_data_struct. Make the space and
2706 subspace dictionaries be pointers (to save space when
2707 only reading objects).
2709 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2710 some references changed. Allocate a copyable data stucture if
2711 none exists. Store info into the copyable data structure.
2712 (bfd_som_set_subsection_attributes): Likewise.
2713 (som_is_space, som_is_subspace, som_is_container): New functions.
2714 Use these instead of directly accessing private data.
2715 (som_prep_headers): Allocate space and subspace headers here.
2716 Fill in some fields in the space/subspace headers from the
2718 (som_bfd_copy_private_section_data): Only copy the stuff
2719 that we really need to make objcopy and strip work. Allocate
2720 the copy_data structure for the output bfd before copying.
2722 * som.h (struct som_exec_data): New structure to hold exec
2723 info that must be preserved when running objcopy/strip.
2724 (struct somdata): Add new "exec_data" field and accessor
2725 macro. Add some comments on how the various fields are used.
2726 (som_section_data_struct): Make is_space and is_subspace bitfields.
2727 Delete unused subspace_index. All references now use the
2728 target_index field within the section structure itself.
2730 * som.c (make_unique_section): Delete unused declaration.
2731 (som_bfd_copy_private_bfd_data): New function.
2732 (som_object_setup): Allocate space for and save exec information
2733 that needs to be copied during objcopy/strip.
2734 (som_mkobject): Do not allocate space for a file header here.
2735 It is not used when only reading SOM objects.
2736 (som_prep_headers): Allocate space for and attach a file header
2737 to the output bfd. For executables, use the saved system_id
2738 value rather than trying to guess the right value. Do not abort
2739 wwhen setting file_hdr->entry* for executables.
2740 (som_begin_writing): For executables, set the exec_entry and
2742 (som_copy_private_backend_section_data): Always return a value.
2744 * libhppa.h (PA_PAGESIZE): Define.
2746 * som.c (SOM_ALIGN): Define.
2747 (som_begin_writing): If writing an executable, initialize all
2748 fields in the exec header to zero. Update fields in the exec
2749 header as sizes of loadable subspaces are computed. Carefully
2750 preserve alignments when building executables. Actually write the
2751 exec after all the fields are filled in.
2753 * Better long-filename handling. Reads SOM ABI compliant extended
2754 names, but doesn't quite write compliant extended names yet.
2755 * som.c (som_slurp_extended_name_table): Delete function. The
2756 generic code will handle things correctly.
2757 (som_slurp_armap): Seek to the beginning of the next member.
2758 (normalize): New function.
2759 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2760 name table into account when computing the file offsets in the
2761 SOM dictionary. Make sure to align to an even boundary.
2762 (som_write_armap): Initialize the checksum to zero.
2763 (ar_maxchars): Fix. Opps.
2765 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2767 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2768 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2770 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2772 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2773 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2774 * bfd-in2.h: Regenerated.
2776 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2777 this was also named trad_unix_bfd_copy_private_bfd_data.
2779 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2781 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2782 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2783 returns NULL, it is not an error. It's possible that some of
2784 these checks are not necessary (because the size can never be
2785 zero), but putting in the checks is the conservative thing to do
2786 in light of the fact that some of these malloc calls replaced
2787 unchecked alloca calls, in which a zero argument would work fine.
2789 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2791 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2792 duplicate definition.
2793 (osf_core_bfd_is_local_label): Define.
2795 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2796 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2797 failure indication, it merely means there are no relocs.
2799 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2800 after NAME, since SunOS /bin/cc can't handle it.
2802 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2804 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2805 From sukes@glue.umd.edu (Tasuki Hirata).
2807 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2809 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2810 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2811 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2813 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2815 * som.c (som_prep_for_fixups): Detect section symbols based
2816 on either the lack of private data or the symbol flags. Do not
2817 munge section symbol names anymore -- they no longer confuse GDB.
2818 (som_begin_writing): Leave space for an exec header if writing
2820 (som_slurp_symbol_table): Recognize both forms of section symbol
2821 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2822 section symbols to be the name of the section they represent.
2823 Debugging symbols begin with "L$0\001", not just "L$".
2825 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2827 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2829 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2830 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2831 and bfd_is_local_label.
2833 * targets.c: Add new entries to the bfd_target structure.
2835 * bfd.c (bfd_copy_private_bfd_data): New definition.
2837 * section.c (bfd_copy_private_section_data): New definition.
2839 * syms.c (bfd_is_local_label): New definition.
2841 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2843 * libbfd.c (bfd_generic_is_local_label): New function.
2845 * *-core.c: Provide default definitions for new functions in
2846 the target vector which all point to bfd_false.
2848 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2849 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2850 Default new vectors for copying private backend data to bfd_true.
2851 Default new vector for determining if a symbol is a local label
2852 to bfd_generic_is_local_label.
2854 * som.c (som_bfd_copy_private_section_data): New function.
2855 (som_bfd_is_local_label): New function.
2856 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2858 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2860 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2862 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2864 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2867 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2868 Indent some of them to GNU standards.
2870 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2871 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2872 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2873 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2874 Update copyright years.
2876 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2878 * som.c (som_prep_for_fixups): A relocation involving the section
2879 symbol for the *ABS* section is really a relocation involving
2881 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2882 undefined symbols. Correctly distinguish between debugger symbols
2883 and section symbols.
2885 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2886 for spaces and subspaces.
2888 * som.c (som_bfd_count_ar_symbols): Fix typo.
2890 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2891 HAS_RELOC based on the object's magic number.
2892 (make_unique_section): Delete function. BFD and its users are
2893 prepared to handle multiple sections with the same name.
2894 (setup_sections): Allocate space on the BFD's obstack to hold
2895 section names. Use bfd_make_setion_anyway rather than the
2896 obsolete make_unique_section.
2897 (som_prep_headers): Choose the correct SOM magic number based
2899 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2901 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2903 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2913 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2914 is always located at the start of the data section to allow
2915 recovery of the dynamic info from a stripped executable.
2916 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2919 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2921 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2922 cruft (like the #pragma alloca for AIX).
2923 In addition to that problem, the C alloca calls xmalloc, which
2924 means checking for being out of memory can't work right. The
2925 following changes remove all uses of alloca from BFD.
2926 * hosts/solaris2.h: Remove alloca cruft.
2927 * som.c: Replace alloca with a fixed size auto array.

2933 * libbfd.h: Rebuilt.
2935 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2937 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2940 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2942 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2943 Elf*_Off typedefs by their expansion, the typedefs have been
2944 removed from include/elf/internal.h.
2945 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2946 SHT_PROGBITS section.
2948 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2950 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2954 * configure.host: Recognize i[34]86-sequent-*.
2956 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2957 return from bfd_seek indicates an error.
2958 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2959 TRAD_CORE_STACK_OFFSET.
2960 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2961 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2963 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2965 * som.[ch]: Do not include libhppa.h in som.c, instead include
2968 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2969 include it in elf32-hppa.h.
2971 * som.c (log2): Return -1 on error rather than aborting.
2972 (setup_sections): Bubble up an error from log2.
2974 * Changes to make HP C compiler happy in both traditional
2976 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2978 (bfd_som_set_section_attributes): Use unsigned int rather than
2979 unsigned char to avoid GNU-C extensions.
2980 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2981 or failure rather than aborting on failure.
2983 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2985 (bfd_som_attach_aux_hdr): Add prototype.
2986 (hppa_som-gen_reloc_type): Likewise.
2988 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2989 (hppa_look_for_stubs_in_section): Do not return false on failure
2990 until rest of code is ready to handle it. Abort for now.
2992 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2994 * bfd-in2.h: Rebuilt.
2996 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

3015 action in case where caller specified no argument relocation.
3016 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3017 right in the original relocation and the stub's relocation.
3019 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3020 unused symbols argument.
3022 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3023 than asymbol * for original target symbol. All callers changed.
3024 Set reloc->sym_ptr_ptr appropriately.
3025 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3026 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3027 argument. Use the output symbols when canonicalizing the relocs,
3028 creating them if necessary.
3030 * linker.c (_bfd_generic_link_output_symbols): Do not

3051 linker stubs into a single function (so they can easily share a

3275 (b_out_relax_section): If a section contains no relocations, don't
3276 bother processing them.
3277 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3981 way to write exports, so add a write_export field to the backend
3982 data (and set it to NULL for everything but the sparc).

5237 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
5239 * config.bfd: Use bigmips for mips*-*-bsd*.
5241 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5243 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
5244 Handle symbol number of zero.
5246 * reloc.c (enum bfd_reloc_code_real): Added
5247 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
5248 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
5249 * bfd-in2.h: Rebuilt.
5250 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
5251 BFD_RELOC_MIPS_LITERAL.
5252 * elf32-mips.c (mips_reloc_map): Handle new relocs.
5253 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
5256 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
5257 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
5258 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
5259 MY_bfd_seclet_link): Define.
5260 (MY_bfd_reloc_type_lookup): Rename from
5261 MY_reloc_howto_type_lookup.
5262 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
5263 (MY(vec)): Use JUMP_TABLE rather than listing functions.
5264 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
5265 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
5266 terms of MY, because that causes a recusive invocation of CAT when
5267 expanded within JUMP_TABLE, and ANSI compilers don't expand
5269 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
5270 MY_reloc_howto_type_lookup, and don't define in terms of MY.
5271 (MY_canonicalize_reloc): Don't define in terms of MY.
5272 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
5273 than listing functions.
5275 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
5277 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
