2589 * libbfd-in.h (_bfd_generic_link_add_symbols_collect): Declare.
2590 * libbfd.h: Rebuilt.
2592 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2594 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2595 for first character in an extended name.
2596 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2597 "//" as the name of the special archive member holding the
2598 extended name table.
2600 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2602 Support for link_order types which generate relocs in order to
2603 support -Ur in the linker.
2604 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2605 from call to _bfd_generic_link_add_one_symbol.
2606 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2607 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2608 instead of bitsize to add_to_set call back.
2609 (_bfd_generic_final_link): Account for link_order relocs when
2610 allocating space for relocations. Handle them in link_order loop.
2611 (_bfd_generic_reloc_link_order): New function.
2612 (_bfd_default_link_order): If a reloc_link_order is seen here,
2614 (_bfd_count_link_order_relocs): New function.
2615 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2616 argument from declaration.
2617 (_bfd_generic_reloc_link_order): Declare.
2618 (_bfd_count_link_order_relocs): Declare.
2619 * libbfd.h: Rebuilt.
2620 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2621 call to _bfd_generic_link_add_one_symbol.
2622 (NAME(aout,final_link)): Account for link_order relocs when
2623 allocating space for relocations. Handle them after handling all
2625 (aout_link_reloc_link_order): New function.
2626 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
2627 call to _bfd_generic_link_add_one_symbol.
2628 (ecoff_bfd_final_link): Account for link_order relocs when
2629 allocating space for relocations. Handle them in link_order loop.
2630 (ecoff_link_write_external): Set the storage class of a defined
2631 linker created symbol based on the section it is in. Correct
2632 bfd_link_hash_weak case to use .sc rather than .st.
2633 (ecoff_reloc_link_order): New function.
2634 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2636 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2638 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2641 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2642 bfd_zmalloc. Free a pointer, not a union.
2643 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2645 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2647 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2649 * som.c (bfd_section_from_som_symbol): Only to do the value
2650 comparison for function symbols within executables.
2652 * som.c (bfd_section_from_som_symbol): Renamed from
2653 som_section_from_subspace_index. Pass in a native SOM symbol.
2654 For executables, iterate through the sections to find out
2655 which contains the symbol's address rather than using the
2656 symbol_info field. (symbol_info has a different meaning for
2657 dynamicly linked executables.)
2659 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2662 * som.c (som_begin_writing): Fix braino (one call to align
2663 space/subspace data was done unconditionally rather than
2664 just for executables.)
2666 * som.c (som_begin_writing): Align text in all executables to
2667 make HPUX kernel happy. Fixes strip/objcopy for shared
2670 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2672 * som.c (som_begin_writing): Account for alignment needs of
2673 subspaces too when writing executables. Never request a negative
2674 bss size. Fixes some problems with demand paged executables,
2675 still having problems with pure executables and shared executables.
2677 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2679 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2680 bfd_zalloc for rawptr, because later on we may call free, not
2683 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2684 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2685 * cisco-core.c: New file.
2686 * Makefile.in: Change accordingly.
2687 * configure.in: Recognize cisco_core_vec.
2688 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2689 * targets.c: Add cisco_core_vec.
2690 * bfd-in2.h: Rebuilt.
2692 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2694 * som.h (som_copyable_section_data_struct): New structure
2695 containing all the private section information which needs
2696 to be copied from input section to output section during
2698 (som_section_data_struct): Remove several fields now in
2699 som_copyable_section_data_struct. Make the space and
2700 subspace dictionaries be pointers (to save space when
2701 only reading objects).
2703 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2704 some references changed. Allocate a copyable data stucture if
2705 none exists. Store info into the copyable data structure.
2706 (bfd_som_set_subsection_attributes): Likewise.
2707 (som_is_space, som_is_subspace, som_is_container): New functions.
2708 Use these instead of directly accessing private data.
2709 (som_prep_headers): Allocate space and subspace headers here.
2710 Fill in some fields in the space/subspace headers from the
2712 (som_bfd_copy_private_section_data): Only copy the stuff
2713 that we really need to make objcopy and strip work. Allocate
2714 the copy_data structure for the output bfd before copying.
2716 * som.h (struct som_exec_data): New structure to hold exec
2717 info that must be preserved when running objcopy/strip.
2718 (struct somdata): Add new "exec_data" field and accessor
2719 macro. Add some comments on how the various fields are used.
2720 (som_section_data_struct): Make is_space and is_subspace bitfields.
2721 Delete unused subspace_index. All references now use the
2722 target_index field within the section structure itself.
2724 * som.c (make_unique_section): Delete unused declaration.
2725 (som_bfd_copy_private_bfd_data): New function.
2726 (som_object_setup): Allocate space for and save exec information
2727 that needs to be copied during objcopy/strip.
2728 (som_mkobject): Do not allocate space for a file header here.
2729 It is not used when only reading SOM objects.
2730 (som_prep_headers): Allocate space for and attach a file header
2731 to the output bfd. For executables, use the saved system_id
2732 value rather than trying to guess the right value. Do not abort
2733 wwhen setting file_hdr->entry* for executables.
2734 (som_begin_writing): For executables, set the exec_entry and
2736 (som_copy_private_backend_section_data): Always return a value.
2738 * libhppa.h (PA_PAGESIZE): Define.
2740 * som.c (SOM_ALIGN): Define.
2741 (som_begin_writing): If writing an executable, initialize all
2742 fields in the exec header to zero. Update fields in the exec
2743 header as sizes of loadable subspaces are computed. Carefully
2744 preserve alignments when building executables. Actually write the
2745 exec after all the fields are filled in.
2747 * Better long-filename handling. Reads SOM ABI compliant extended
2748 names, but doesn't quite write compliant extended names yet.
2749 * som.c (som_slurp_extended_name_table): Delete function. The
2750 generic code will handle things correctly.
2751 (som_slurp_armap): Seek to the beginning of the next member.
2752 (normalize): New function.
2753 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2754 name table into account when computing the file offsets in the
2755 SOM dictionary. Make sure to align to an even boundary.
2756 (som_write_armap): Initialize the checksum to zero.
2757 (ar_maxchars): Fix. Opps.
2759 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2761 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2762 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2764 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2766 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2767 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2768 * bfd-in2.h: Regenerated.
2770 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2771 this was also named trad_unix_bfd_copy_private_bfd_data.
2773 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2775 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2776 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2777 returns NULL, it is not an error. It's possible that some of
2778 these checks are not necessary (because the size can never be
2779 zero), but putting in the checks is the conservative thing to do
2780 in light of the fact that some of these malloc calls replaced
2781 unchecked alloca calls, in which a zero argument would work fine.
2783 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2785 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2786 duplicate definition.
2787 (osf_core_bfd_is_local_label): Define.
2789 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2790 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2791 failure indication, it merely means there are no relocs.
2793 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2794 after NAME, since SunOS /bin/cc can't handle it.
2796 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2798 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2799 From sukes@glue.umd.edu (Tasuki Hirata).
2801 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2803 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2804 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2805 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2807 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2809 * som.c (som_prep_for_fixups): Detect section symbols based
2810 on either the lack of private data or the symbol flags. Do not
2811 munge section symbol names anymore -- they no longer confuse GDB.
2812 (som_begin_writing): Leave space for an exec header if writing
2814 (som_slurp_symbol_table): Recognize both forms of section symbol
2815 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2816 section symbols to be the name of the section they represent.
2817 Debugging symbols begin with "L$0\001", not just "L$".
2819 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2821 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2823 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2824 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2825 and bfd_is_local_label.
2827 * targets.c: Add new entries to the bfd_target structure.
2829 * bfd.c (bfd_copy_private_bfd_data): New definition.
2831 * section.c (bfd_copy_private_section_data): New definition.
2833 * syms.c (bfd_is_local_label): New definition.
2835 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2837 * libbfd.c (bfd_generic_is_local_label): New function.
2839 * *-core.c: Provide default definitions for new functions in
2840 the target vector which all point to bfd_false.
2842 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2843 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2844 Default new vectors for copying private backend data to bfd_true.
2845 Default new vector for determining if a symbol is a local label
2846 to bfd_generic_is_local_label.
2848 * som.c (som_bfd_copy_private_section_data): New function.
2849 (som_bfd_is_local_label): New function.
2850 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2852 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2854 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2856 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2858 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2861 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2862 Indent some of them to GNU standards.
2864 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2865 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2866 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2867 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2868 Update copyright years.
2870 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2872 * som.c (som_prep_for_fixups): A relocation involving the section
2873 symbol for the *ABS* section is really a relocation involving
2875 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2876 undefined symbols. Correctly distinguish between debugger symbols
2877 and section symbols.
2879 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2880 for spaces and subspaces.
2882 * som.c (som_bfd_count_ar_symbols): Fix typo.
2884 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2885 HAS_RELOC based on the object's magic number.
2886 (make_unique_section): Delete function. BFD and its users are
2887 prepared to handle multiple sections with the same name.
2888 (setup_sections): Allocate space on the BFD's obstack to hold
2889 section names. Use bfd_make_setion_anyway rather than the
2890 obsolete make_unique_section.
2891 (som_prep_headers): Choose the correct SOM magic number based
2893 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2895 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2897 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2898 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2899 * Makefile.in, configure.in: Corresponding changes.

2907 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2908 is always located at the start of the data section to allow
2909 recovery of the dynamic info from a stripped executable.
2910 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2913 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2915 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2916 cruft (like the #pragma alloca for AIX).
2917 In addition to that problem, the C alloca calls xmalloc, which
2918 means checking for being out of memory can't work right. The
2919 following changes remove all uses of alloca from BFD.
2920 * hosts/solaris2.h: Remove alloca cruft.
2921 * som.c: Replace alloca with a fixed size auto array.

2927 * libbfd.h: Rebuilt.
2929 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2931 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2934 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2936 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2937 Elf*_Off typedefs by their expansion, the typedefs have been
2938 removed from include/elf/internal.h.
2939 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2940 SHT_PROGBITS section.
2942 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2944 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2950 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2951 return from bfd_seek indicates an error.
2952 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2953 TRAD_CORE_STACK_OFFSET.
2954 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2955 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2957 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2959 * som.[ch]: Do not include libhppa.h in som.c, instead include
2962 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2963 include it in elf32-hppa.h.
2965 * som.c (log2): Return -1 on error rather than aborting.
2966 (setup_sections): Bubble up an error from log2.
2968 * Changes to make HP C compiler happy in both traditional
2970 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2972 (bfd_som_set_section_attributes): Use unsigned int rather than
2973 unsigned char to avoid GNU-C extensions.
2974 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2975 or failure rather than aborting on failure.
2977 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2979 (bfd_som_attach_aux_hdr): Add prototype.
2980 (hppa_som-gen_reloc_type): Likewise.
2982 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2983 (hppa_look_for_stubs_in_section): Do not return false on failure
2984 until rest of code is ready to handle it. Abort for now.

3009 action in case where caller specified no argument relocation.
3010 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3011 right in the original relocation and the stub's relocation.
3013 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3014 unused symbols argument.
3016 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3017 than asymbol * for original target symbol. All callers changed.
3018 Set reloc->sym_ptr_ptr appropriately.
3019 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3020 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3021 argument. Use the output symbols when canonicalizing the relocs,
3022 creating them if necessary.
3024 * linker.c (_bfd_generic_link_output_symbols): Do not
3025 rebuild/clobber the output symbols if they already exist.
3027 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3029 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3030 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3031 * bfd-in2.h: Rebuilt.
3033 * srec.c (hex_value): Always set to a size of 256 bytes.
3034 (srec_init): Cosmetic changes.
3036 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3038 * elf32-hppa.c: Second half of major cleanup. More comments,
3039 PARAMize and staticize rest of functions. Delete unused
3040 functions. Delete unused/unnecessary arguments to some functions.
3041 Group static vars together. Abort for bad errors until we have

3044 #defines for lots of things. Merge two functions which build
3045 linker stubs into a single function (so they can easily share a
3046 ton of common code).

3270 bother processing them.
3271 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3275 that reloc->addend falls between the current source offset and the
3276 raw size of the input section.

3355 Make all callers of malloc or realloc (including via obstacks)
3356 check the result for NULL. Most set bfd_error to no_memory and

5242 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
5243 * bfd-in2.h: Rebuilt.
5244 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
5245 BFD_RELOC_MIPS_LITERAL.
5246 * elf32-mips.c (mips_reloc_map): Handle new relocs.
5247 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
5250 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
5251 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
5252 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
5253 MY_bfd_seclet_link): Define.
5254 (MY_bfd_reloc_type_lookup): Rename from
5255 MY_reloc_howto_type_lookup.
5256 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
5257 (MY(vec)): Use JUMP_TABLE rather than listing functions.
5258 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
5259 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
5260 terms of MY, because that causes a recusive invocation of CAT when
5261 expanded within JUMP_TABLE, and ANSI compilers don't expand
5263 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
5264 MY_reloc_howto_type_lookup, and don't define in terms of MY.
5265 (MY_canonicalize_reloc): Don't define in terms of MY.
5266 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
5267 than listing functions.
