2622 in asymbol udata field.
2624 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2626 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2627 reloc, used in embedded PIC code.
2628 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2635 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2636 add_symbls entry point.
2638 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2639 counting relocs. Set SEC_RELOC flag for any section which has

2644 * linker.c (_bfd_generic_link_add_symbols): Just call
2645 generic_link_add_symbols.
2646 (_bfd_generic_link_add_symbols_collect): New function, like
2647 _bfd_generic_link_add_symbols but also collect constructors and
2648 destructors by name as collect2 does.
2649 (generic_link_add_symbols): New function, like old
2650 _bfd_generic_link_add_symbols but with collect argument.
2651 (generic_link_add_object_symbols): Take collect argument.

2663 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2664 for first character in an extended name.
2665 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2666 "//" as the name of the special archive member holding the
2667 extended name table.
2669 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2671 Support for link_order types which generate relocs in order to
2672 support -Ur in the linker.
2673 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2674 from call to _bfd_generic_link_add_one_symbol.
2675 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2676 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2677 instead of bitsize to add_to_set call back.
2678 (_bfd_generic_final_link): Account for link_order relocs when
2679 allocating space for relocations. Handle them in link_order loop.
2680 (_bfd_generic_reloc_link_order): New function.
2681 (_bfd_default_link_order): If a reloc_link_order is seen here,
2683 (_bfd_count_link_order_relocs): New function.
2684 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2685 argument from declaration.
2686 (_bfd_generic_reloc_link_order): Declare.
2687 (_bfd_count_link_order_relocs): Declare.

2689 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2690 call to _bfd_generic_link_add_one_symbol.

2696 call to _bfd_generic_link_add_one_symbol.
2697 (ecoff_bfd_final_link): Account for link_order relocs when
2698 allocating space for relocations. Handle them in link_order loop.
2699 (ecoff_link_write_external): Set the storage class of a defined
2700 linker created symbol based on the section it is in. Correct
2701 bfd_link_hash_weak case to use .sc rather than .st.
2702 (ecoff_reloc_link_order): New function.
2703 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2705 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2710 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2711 bfd_zmalloc. Free a pointer, not a union.
2712 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2714 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2716 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2718 * som.c (bfd_section_from_som_symbol): Only to do the value
2719 comparison for function symbols within executables.
2721 * som.c (bfd_section_from_som_symbol): Renamed from
2722 som_section_from_subspace_index. Pass in a native SOM symbol.
2723 For executables, iterate through the sections to find out
2724 which contains the symbol's address rather than using the
2725 symbol_info field. (symbol_info has a different meaning for
2726 dynamicly linked executables.)
2728 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2731 * som.c (som_begin_writing): Fix braino (one call to align
2732 space/subspace data was done unconditionally rather than
2733 just for executables.)
2735 * som.c (som_begin_writing): Align text in all executables to
2736 make HPUX kernel happy. Fixes strip/objcopy for shared
2739 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2741 * som.c (som_begin_writing): Account for alignment needs of
2742 subspaces too when writing executables. Never request a negative
2743 bss size. Fixes some problems with demand paged executables,
2744 still having problems with pure executables and shared executables.
2746 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2748 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2749 bfd_zalloc for rawptr, because later on we may call free, not
2752 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2753 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2754 * cisco-core.c: New file.
2755 * Makefile.in: Change accordingly.
2756 * configure.in: Recognize cisco_core_vec.
2757 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2758 * targets.c: Add cisco_core_vec.
2759 * bfd-in2.h: Rebuilt.
2761 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2763 * som.h (som_copyable_section_data_struct): New structure
2764 containing all the private section information which needs
2765 to be copied from input section to output section during
2767 (som_section_data_struct): Remove several fields now in
2768 som_copyable_section_data_struct. Make the space and
2769 subspace dictionaries be pointers (to save space when
2770 only reading objects).
2772 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2773 some references changed. Allocate a copyable data stucture if
2774 none exists. Store info into the copyable data structure.
2775 (bfd_som_set_subsection_attributes): Likewise.
2776 (som_is_space, som_is_subspace, som_is_container): New functions.
2777 Use these instead of directly accessing private data.
2778 (som_prep_headers): Allocate space and subspace headers here.
2779 Fill in some fields in the space/subspace headers from the
2781 (som_bfd_copy_private_section_data): Only copy the stuff
2782 that we really need to make objcopy and strip work. Allocate
2783 the copy_data structure for the output bfd before copying.
2785 * som.h (struct som_exec_data): New structure to hold exec
2786 info that must be preserved when running objcopy/strip.
2787 (struct somdata): Add new "exec_data" field and accessor
2788 macro. Add some comments on how the various fields are used.
2789 (som_section_data_struct): Make is_space and is_subspace bitfields.
2790 Delete unused subspace_index. All references now use the
2791 target_index field within the section structure itself.
2793 * som.c (make_unique_section): Delete unused declaration.
2794 (som_bfd_copy_private_bfd_data): New function.
2795 (som_object_setup): Allocate space for and save exec information
2796 that needs to be copied during objcopy/strip.
2797 (som_mkobject): Do not allocate space for a file header here.
2798 It is not used when only reading SOM objects.
2799 (som_prep_headers): Allocate space for and attach a file header
2800 to the output bfd. For executables, use the saved system_id
2801 value rather than trying to guess the right value. Do not abort
2802 wwhen setting file_hdr->entry* for executables.
2803 (som_begin_writing): For executables, set the exec_entry and
2805 (som_copy_private_backend_section_data): Always return a value.
2807 * libhppa.h (PA_PAGESIZE): Define.
2809 * som.c (SOM_ALIGN): Define.
2810 (som_begin_writing): If writing an executable, initialize all
2811 fields in the exec header to zero. Update fields in the exec
2812 header as sizes of loadable subspaces are computed. Carefully
2813 preserve alignments when building executables. Actually write the
2814 exec after all the fields are filled in.
2816 * Better long-filename handling. Reads SOM ABI compliant extended
2817 names, but doesn't quite write compliant extended names yet.
2818 * som.c (som_slurp_extended_name_table): Delete function. The
2819 generic code will handle things correctly.
2820 (som_slurp_armap): Seek to the beginning of the next member.
2821 (normalize): New function.
2822 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2823 name table into account when computing the file offsets in the
2824 SOM dictionary. Make sure to align to an even boundary.
2825 (som_write_armap): Initialize the checksum to zero.
2826 (ar_maxchars): Fix. Opps.
2828 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2830 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2831 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2833 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2835 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2836 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2837 * bfd-in2.h: Regenerated.
2839 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2840 this was also named trad_unix_bfd_copy_private_bfd_data.
2842 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2844 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2845 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2846 returns NULL, it is not an error. It's possible that some of
2847 these checks are not necessary (because the size can never be
2848 zero), but putting in the checks is the conservative thing to do
2849 in light of the fact that some of these malloc calls replaced
2850 unchecked alloca calls, in which a zero argument would work fine.
2852 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2854 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2855 duplicate definition.
2856 (osf_core_bfd_is_local_label): Define.
2858 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2859 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2860 failure indication, it merely means there are no relocs.
2862 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2863 after NAME, since SunOS /bin/cc can't handle it.
2865 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2867 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2868 From sukes@glue.umd.edu (Tasuki Hirata).
2870 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2872 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2873 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2874 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2876 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2878 * som.c (som_prep_for_fixups): Detect section symbols based
2879 on either the lack of private data or the symbol flags. Do not
2880 munge section symbol names anymore -- they no longer confuse GDB.
2881 (som_begin_writing): Leave space for an exec header if writing
2883 (som_slurp_symbol_table): Recognize both forms of section symbol
2884 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2885 section symbols to be the name of the section they represent.
2886 Debugging symbols begin with "L$0\001", not just "L$".
2888 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2890 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2892 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2893 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2894 and bfd_is_local_label.
2896 * targets.c: Add new entries to the bfd_target structure.
2898 * bfd.c (bfd_copy_private_bfd_data): New definition.
2900 * section.c (bfd_copy_private_section_data): New definition.

2906 * libbfd.c (bfd_generic_is_local_label): New function.
2908 * *-core.c: Provide default definitions for new functions in
2909 the target vector which all point to bfd_false.
2911 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2912 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2913 Default new vectors for copying private backend data to bfd_true.
2914 Default new vector for determining if a symbol is a local label
2915 to bfd_generic_is_local_label.
2917 * som.c (som_bfd_copy_private_section_data): New function.
2918 (som_bfd_is_local_label): New function.
2919 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2921 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2923 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2925 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2927 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2930 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2931 Indent some of them to GNU standards.
2933 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2934 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2935 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2936 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2937 Update copyright years.
2939 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2941 * som.c (som_prep_for_fixups): A relocation involving the section
2942 symbol for the *ABS* section is really a relocation involving
2944 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2945 undefined symbols. Correctly distinguish between debugger symbols
2946 and section symbols.
2948 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2949 for spaces and subspaces.
2951 * som.c (som_bfd_count_ar_symbols): Fix typo.
2953 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2954 HAS_RELOC based on the object's magic number.
2955 (make_unique_section): Delete function. BFD and its users are
2956 prepared to handle multiple sections with the same name.
2957 (setup_sections): Allocate space on the BFD's obstack to hold
2958 section names. Use bfd_make_setion_anyway rather than the
2959 obsolete make_unique_section.
2960 (som_prep_headers): Choose the correct SOM magic number based
2962 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2964 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2966 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2976 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2977 is always located at the start of the data section to allow
2978 recovery of the dynamic info from a stripped executable.
2979 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2982 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2984 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2985 cruft (like the #pragma alloca for AIX).
2986 In addition to that problem, the C alloca calls xmalloc, which
2987 means checking for being out of memory can't work right. The
2988 following changes remove all uses of alloca from BFD.
2989 * hosts/solaris2.h: Remove alloca cruft.
2990 * som.c: Replace alloca with a fixed size auto array.

2995 * linker.c: Replace alloca with obstack_alloc.
2996 * libbfd.h: Rebuilt.
2998 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3000 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3003 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3005 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3006 Elf*_Off typedefs by their expansion, the typedefs have been
3007 removed from include/elf/internal.h.
3008 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3009 SHT_PROGBITS section.
3011 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3013 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
3015 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3017 * configure.host: Recognize i[34]86-sequent-*.
3019 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3020 return from bfd_seek indicates an error.
3021 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3022 TRAD_CORE_STACK_OFFSET.
3023 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3024 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3026 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3028 * som.[ch]: Do not include libhppa.h in som.c, instead include

3339 bother processing them.
3340 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4043 The sparc (and possibly other?) NLM format requires a different
4044 way to write exports, so add a write_export field to the backend
4045 data (and set it to NULL for everything but the sparc).
