2586 * libbfd-in.h (_bfd_generic_link_add_symbols_collect): Declare.
2587 * libbfd.h: Rebuilt.
2589 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2591 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2592 for first character in an extended name.
2593 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2594 "//" as the name of the special archive member holding the
2595 extended name table.
2597 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2599 Support for link_order types which generate relocs in order to
2600 support -Ur in the linker.
2601 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2602 from call to _bfd_generic_link_add_one_symbol.
2603 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2604 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2605 instead of bitsize to add_to_set call back.
2606 (_bfd_generic_final_link): Account for link_order relocs when
2607 allocating space for relocations. Handle them in link_order loop.
2608 (_bfd_generic_reloc_link_order): New function.
2609 (_bfd_default_link_order): If a reloc_link_order is seen here,
2611 (_bfd_count_link_order_relocs): New function.
2612 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2613 argument from declaration.
2614 (_bfd_generic_reloc_link_order): Declare.
2615 (_bfd_count_link_order_relocs): Declare.
2616 * libbfd.h: Rebuilt.
2617 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2618 call to _bfd_generic_link_add_one_symbol.
2619 (NAME(aout,final_link)): Account for link_order relocs when
2620 allocating space for relocations. Handle them after handling all
2622 (aout_link_reloc_link_order): New function.
2623 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
2624 call to _bfd_generic_link_add_one_symbol.
2625 (ecoff_bfd_final_link): Account for link_order relocs when
2626 allocating space for relocations. Handle them in link_order loop.
2627 (ecoff_link_write_external): Set the storage class of a defined
2628 linker created symbol based on the section it is in. Correct
2629 bfd_link_hash_weak case to use .sc rather than .st.
2630 (ecoff_reloc_link_order): New function.
2631 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2633 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2635 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2638 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2639 bfd_zmalloc. Free a pointer, not a union.
2640 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2642 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2644 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2646 * som.c (bfd_section_from_som_symbol): Only to do the value
2647 comparison for function symbols within executables.
2649 * som.c (bfd_section_from_som_symbol): Renamed from
2650 som_section_from_subspace_index. Pass in a native SOM symbol.
2651 For executables, iterate through the sections to find out
2652 which contains the symbol's address rather than using the
2653 symbol_info field. (symbol_info has a different meaning for
2654 dynamicly linked executables.)
2656 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2659 * som.c (som_begin_writing): Fix braino (one call to align
2660 space/subspace data was done unconditionally rather than
2661 just for executables.)
2663 * som.c (som_begin_writing): Align text in all executables to
2664 make HPUX kernel happy. Fixes strip/objcopy for shared
2667 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2669 * som.c (som_begin_writing): Account for alignment needs of
2670 subspaces too when writing executables. Never request a negative
2671 bss size. Fixes some problems with demand paged executables,
2672 still having problems with pure executables and shared executables.
2674 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2676 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2677 bfd_zalloc for rawptr, because later on we may call free, not
2680 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2681 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2682 * cisco-core.c: New file.
2683 * Makefile.in: Change accordingly.
2684 * configure.in: Recognize cisco_core_vec.
2685 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2686 * targets.c: Add cisco_core_vec.
2687 * bfd-in2.h: Rebuilt.
2689 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2691 * som.h (som_copyable_section_data_struct): New structure
2692 containing all the private section information which needs
2693 to be copied from input section to output section during
2695 (som_section_data_struct): Remove several fields now in
2696 som_copyable_section_data_struct. Make the space and
2697 subspace dictionaries be pointers (to save space when
2698 only reading objects).
2700 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2701 some references changed. Allocate a copyable data stucture if
2702 none exists. Store info into the copyable data structure.
2703 (bfd_som_set_subsection_attributes): Likewise.
2704 (som_is_space, som_is_subspace, som_is_container): New functions.
2705 Use these instead of directly accessing private data.
2706 (som_prep_headers): Allocate space and subspace headers here.
2707 Fill in some fields in the space/subspace headers from the
2709 (som_bfd_copy_private_section_data): Only copy the stuff
2710 that we really need to make objcopy and strip work. Allocate
2711 the copy_data structure for the output bfd before copying.
2713 * som.h (struct som_exec_data): New structure to hold exec
2714 info that must be preserved when running objcopy/strip.
2715 (struct somdata): Add new "exec_data" field and accessor
2716 macro. Add some comments on how the various fields are used.
2717 (som_section_data_struct): Make is_space and is_subspace bitfields.
2718 Delete unused subspace_index. All references now use the
2719 target_index field within the section structure itself.
2721 * som.c (make_unique_section): Delete unused declaration.
2722 (som_bfd_copy_private_bfd_data): New function.
2723 (som_object_setup): Allocate space for and save exec information
2724 that needs to be copied during objcopy/strip.
2725 (som_mkobject): Do not allocate space for a file header here.
2726 It is not used when only reading SOM objects.
2727 (som_prep_headers): Allocate space for and attach a file header
2728 to the output bfd. For executables, use the saved system_id
2729 value rather than trying to guess the right value. Do not abort
2730 wwhen setting file_hdr->entry* for executables.
2731 (som_begin_writing): For executables, set the exec_entry and
2733 (som_copy_private_backend_section_data): Always return a value.
2735 * libhppa.h (PA_PAGESIZE): Define.
2737 * som.c (SOM_ALIGN): Define.
2738 (som_begin_writing): If writing an executable, initialize all
2739 fields in the exec header to zero. Update fields in the exec
2740 header as sizes of loadable subspaces are computed. Carefully
2741 preserve alignments when building executables. Actually write the
2742 exec after all the fields are filled in.
2744 * Better long-filename handling. Reads SOM ABI compliant extended
2745 names, but doesn't quite write compliant extended names yet.
2746 * som.c (som_slurp_extended_name_table): Delete function. The
2747 generic code will handle things correctly.
2748 (som_slurp_armap): Seek to the beginning of the next member.
2749 (normalize): New function.
2750 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2751 name table into account when computing the file offsets in the
2752 SOM dictionary. Make sure to align to an even boundary.
2753 (som_write_armap): Initialize the checksum to zero.
2754 (ar_maxchars): Fix. Opps.
2756 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2758 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2759 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2761 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2763 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2764 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2765 * bfd-in2.h: Regenerated.
2767 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2768 this was also named trad_unix_bfd_copy_private_bfd_data.
2770 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2772 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2773 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2774 returns NULL, it is not an error. It's possible that some of
2775 these checks are not necessary (because the size can never be
2776 zero), but putting in the checks is the conservative thing to do
2777 in light of the fact that some of these malloc calls replaced
2778 unchecked alloca calls, in which a zero argument would work fine.
2780 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2782 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2783 duplicate definition.
2784 (osf_core_bfd_is_local_label): Define.
2786 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2787 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2788 failure indication, it merely means there are no relocs.
2790 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2791 after NAME, since SunOS /bin/cc can't handle it.
2793 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2795 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2796 From sukes@glue.umd.edu (Tasuki Hirata).
2798 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2800 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2801 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2802 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2804 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2806 * som.c (som_prep_for_fixups): Detect section symbols based
2807 on either the lack of private data or the symbol flags. Do not
2808 munge section symbol names anymore -- they no longer confuse GDB.
2809 (som_begin_writing): Leave space for an exec header if writing
2811 (som_slurp_symbol_table): Recognize both forms of section symbol
2812 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2813 section symbols to be the name of the section they represent.
2814 Debugging symbols begin with "L$0\001", not just "L$".
2816 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2818 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2820 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2821 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2822 and bfd_is_local_label.
2824 * targets.c: Add new entries to the bfd_target structure.
2826 * bfd.c (bfd_copy_private_bfd_data): New definition.
2828 * section.c (bfd_copy_private_section_data): New definition.
2830 * syms.c (bfd_is_local_label): New definition.
2832 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2834 * libbfd.c (bfd_generic_is_local_label): New function.
2836 * *-core.c: Provide default definitions for new functions in
2837 the target vector which all point to bfd_false.
2839 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2840 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2841 Default new vectors for copying private backend data to bfd_true.
2842 Default new vector for determining if a symbol is a local label
2843 to bfd_generic_is_local_label.
2845 * som.c (som_bfd_copy_private_section_data): New function.
2846 (som_bfd_is_local_label): New function.
2847 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2849 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2851 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2853 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2855 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2858 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2859 Indent some of them to GNU standards.
2861 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2862 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2863 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2864 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2865 Update copyright years.
2867 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2869 * som.c (som_prep_for_fixups): A relocation involving the section
2870 symbol for the *ABS* section is really a relocation involving
2872 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2873 undefined symbols. Correctly distinguish between debugger symbols
2874 and section symbols.
2876 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2877 for spaces and subspaces.
2879 * som.c (som_bfd_count_ar_symbols): Fix typo.
2881 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2882 HAS_RELOC based on the object's magic number.
2883 (make_unique_section): Delete function. BFD and its users are
2884 prepared to handle multiple sections with the same name.
2885 (setup_sections): Allocate space on the BFD's obstack to hold
2886 section names. Use bfd_make_setion_anyway rather than the
2887 obsolete make_unique_section.
2888 (som_prep_headers): Choose the correct SOM magic number based
2890 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2892 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2894 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2895 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.

2904 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2905 is always located at the start of the data section to allow
2906 recovery of the dynamic info from a stripped executable.
2907 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2910 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2912 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2913 cruft (like the #pragma alloca for AIX).
2914 In addition to that problem, the C alloca calls xmalloc, which
2915 means checking for being out of memory can't work right. The
2916 following changes remove all uses of alloca from BFD.
2917 * hosts/solaris2.h: Remove alloca cruft.
2918 * som.c: Replace alloca with a fixed size auto array.

2923 * linker.c: Replace alloca with obstack_alloc.
2924 * libbfd.h: Rebuilt.
2926 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2928 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2931 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2933 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2934 Elf*_Off typedefs by their expansion, the typedefs have been
2935 removed from include/elf/internal.h.
2936 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2937 SHT_PROGBITS section.
2939 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2941 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2945 * configure.host: Recognize i[34]86-sequent-*.
2947 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2948 return from bfd_seek indicates an error.
2949 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2950 TRAD_CORE_STACK_OFFSET.
2951 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2952 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2954 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2956 * som.[ch]: Do not include libhppa.h in som.c, instead include
2959 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2960 include it in elf32-hppa.h.
2962 * som.c (log2): Return -1 on error rather than aborting.
2963 (setup_sections): Bubble up an error from log2.
2965 * Changes to make HP C compiler happy in both traditional
2967 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2969 (bfd_som_set_section_attributes): Use unsigned int rather than
2970 unsigned char to avoid GNU-C extensions.
2971 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2972 or failure rather than aborting on failure.
2974 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2976 (bfd_som_attach_aux_hdr): Add prototype.
2977 (hppa_som-gen_reloc_type): Likewise.
2979 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2980 (hppa_look_for_stubs_in_section): Do not return false on failure
2981 until rest of code is ready to handle it. Abort for now.

3006 action in case where caller specified no argument relocation.
3007 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3008 right in the original relocation and the stub's relocation.
3010 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3011 unused symbols argument.
3013 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3014 than asymbol * for original target symbol. All callers changed.
3015 Set reloc->sym_ptr_ptr appropriately.
3016 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3017 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3018 argument. Use the output symbols when canonicalizing the relocs,
3019 creating them if necessary.
3021 * linker.c (_bfd_generic_link_output_symbols): Do not
3022 rebuild/clobber the output symbols if they already exist.
3024 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3026 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3027 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3028 * bfd-in2.h: Rebuilt.
3030 * srec.c (hex_value): Always set to a size of 256 bytes.
3031 (srec_init): Cosmetic changes.
3033 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3035 * elf32-hppa.c: Second half of major cleanup. More comments,
3036 PARAMize and staticize rest of functions. Delete unused
3037 functions. Delete unused/unnecessary arguments to some functions.
3038 Group static vars together. Abort for bad errors until we have
3039 error code propogation working. Work on spacing and indention.

3042 linker stubs into a single function (so they can easily share a
3043 ton of common code).

3267 bother processing them.
3268 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3352 Make all callers of malloc or realloc (including via obstacks)
3353 check the result for NULL. Most set bfd_error to no_memory and

5241 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
5242 BFD_RELOC_MIPS_LITERAL.
5243 * elf32-mips.c (mips_reloc_map): Handle new relocs.
5244 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
5247 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
5248 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
5249 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
5250 MY_bfd_seclet_link): Define.
5251 (MY_bfd_reloc_type_lookup): Rename from
5252 MY_reloc_howto_type_lookup.
5253 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
5254 (MY(vec)): Use JUMP_TABLE rather than listing functions.
5255 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
5256 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
5257 terms of MY, because that causes a recusive invocation of CAT when
5258 expanded within JUMP_TABLE, and ANSI compilers don't expand
5260 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
5261 MY_reloc_howto_type_lookup, and don't define in terms of MY.
5262 (MY_canonicalize_reloc): Don't define in terms of MY.
5263 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
5264 than listing functions.
