2641 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2643 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2644 reloc, used in embedded PIC code.
2645 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2652 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2653 add_symbls entry point.
2655 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2656 counting relocs. Set SEC_RELOC flag for any section which has

2664 _bfd_generic_link_add_symbols but also collect constructors and
2665 destructors by name as collect2 does.
2666 (generic_link_add_symbols): New function, like old
2667 _bfd_generic_link_add_symbols but with collect argument.

2681 for first character in an extended name.
2682 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2683 "//" as the name of the special archive member holding the
2684 extended name table.
2686 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2688 Support for link_order types which generate relocs in order to
2689 support -Ur in the linker.
2690 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2691 from call to _bfd_generic_link_add_one_symbol.
2692 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2693 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2694 instead of bitsize to add_to_set call back.
2695 (_bfd_generic_final_link): Account for link_order relocs when
2696 allocating space for relocations. Handle them in link_order loop.
2697 (_bfd_generic_reloc_link_order): New function.

2715 allocating space for relocations. Handle them in link_order loop.
2716 (ecoff_link_write_external): Set the storage class of a defined
2717 linker created symbol based on the section it is in. Correct
2718 bfd_link_hash_weak case to use .sc rather than .st.
2719 (ecoff_reloc_link_order): New function.
2720 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2722 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2728 bfd_zmalloc. Free a pointer, not a union.
2729 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2731 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2733 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2735 * som.c (bfd_section_from_som_symbol): Only to do the value
2736 comparison for function symbols within executables.
2738 * som.c (bfd_section_from_som_symbol): Renamed from
2739 som_section_from_subspace_index. Pass in a native SOM symbol.
2740 For executables, iterate through the sections to find out
2741 which contains the symbol's address rather than using the
2742 symbol_info field. (symbol_info has a different meaning for
2743 dynamicly linked executables.)
2745 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2748 * som.c (som_begin_writing): Fix braino (one call to align
2749 space/subspace data was done unconditionally rather than
2750 just for executables.)
2752 * som.c (som_begin_writing): Align text in all executables to
2753 make HPUX kernel happy. Fixes strip/objcopy for shared
2756 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2758 * som.c (som_begin_writing): Account for alignment needs of
2759 subspaces too when writing executables. Never request a negative
2760 bss size. Fixes some problems with demand paged executables,
2761 still having problems with pure executables and shared executables.
2763 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2765 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2766 bfd_zalloc for rawptr, because later on we may call free, not
2769 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2770 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2771 * cisco-core.c: New file.
2772 * Makefile.in: Change accordingly.
2773 * configure.in: Recognize cisco_core_vec.
2774 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2775 * targets.c: Add cisco_core_vec.
2776 * bfd-in2.h: Rebuilt.
2778 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2780 * som.h (som_copyable_section_data_struct): New structure
2781 containing all the private section information which needs
2782 to be copied from input section to output section during
2784 (som_section_data_struct): Remove several fields now in
2785 som_copyable_section_data_struct. Make the space and
2786 subspace dictionaries be pointers (to save space when
2787 only reading objects).
2789 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2790 some references changed. Allocate a copyable data stucture if
2791 none exists. Store info into the copyable data structure.
2792 (bfd_som_set_subsection_attributes): Likewise.
2793 (som_is_space, som_is_subspace, som_is_container): New functions.
2794 Use these instead of directly accessing private data.
2795 (som_prep_headers): Allocate space and subspace headers here.
2796 Fill in some fields in the space/subspace headers from the
2798 (som_bfd_copy_private_section_data): Only copy the stuff
2799 that we really need to make objcopy and strip work. Allocate
2800 the copy_data structure for the output bfd before copying.
2802 * som.h (struct som_exec_data): New structure to hold exec
2803 info that must be preserved when running objcopy/strip.
2804 (struct somdata): Add new "exec_data" field and accessor
2805 macro. Add some comments on how the various fields are used.
2806 (som_section_data_struct): Make is_space and is_subspace bitfields.
2807 Delete unused subspace_index. All references now use the
2808 target_index field within the section structure itself.
2810 * som.c (make_unique_section): Delete unused declaration.
2811 (som_bfd_copy_private_bfd_data): New function.
2812 (som_object_setup): Allocate space for and save exec information
2813 that needs to be copied during objcopy/strip.
2814 (som_mkobject): Do not allocate space for a file header here.
2815 It is not used when only reading SOM objects.
2816 (som_prep_headers): Allocate space for and attach a file header
2817 to the output bfd. For executables, use the saved system_id
2818 value rather than trying to guess the right value. Do not abort
2819 wwhen setting file_hdr->entry* for executables.
2820 (som_begin_writing): For executables, set the exec_entry and
2822 (som_copy_private_backend_section_data): Always return a value.
2824 * libhppa.h (PA_PAGESIZE): Define.
2826 * som.c (SOM_ALIGN): Define.
2827 (som_begin_writing): If writing an executable, initialize all
2828 fields in the exec header to zero. Update fields in the exec
2829 header as sizes of loadable subspaces are computed. Carefully
2830 preserve alignments when building executables. Actually write the
2831 exec after all the fields are filled in.
2833 * Better long-filename handling. Reads SOM ABI compliant extended
2834 names, but doesn't quite write compliant extended names yet.
2835 * som.c (som_slurp_extended_name_table): Delete function. The
2836 generic code will handle things correctly.
2837 (som_slurp_armap): Seek to the beginning of the next member.
2838 (normalize): New function.
2839 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2840 name table into account when computing the file offsets in the
2841 SOM dictionary. Make sure to align to an even boundary.
2842 (som_write_armap): Initialize the checksum to zero.
2843 (ar_maxchars): Fix. Opps.
2845 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2847 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2848 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2850 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2852 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2853 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2854 * bfd-in2.h: Regenerated.
2856 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2857 this was also named trad_unix_bfd_copy_private_bfd_data.
2859 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2861 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2862 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2863 returns NULL, it is not an error. It's possible that some of
2864 these checks are not necessary (because the size can never be
2865 zero), but putting in the checks is the conservative thing to do
2866 in light of the fact that some of these malloc calls replaced
2867 unchecked alloca calls, in which a zero argument would work fine.
2869 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2871 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2872 duplicate definition.
2873 (osf_core_bfd_is_local_label): Define.
2875 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2876 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2877 failure indication, it merely means there are no relocs.
2879 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2880 after NAME, since SunOS /bin/cc can't handle it.
2882 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2884 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2885 From sukes@glue.umd.edu (Tasuki Hirata).
2887 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2889 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2890 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2891 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2893 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2895 * som.c (som_prep_for_fixups): Detect section symbols based
2896 on either the lack of private data or the symbol flags. Do not
2897 munge section symbol names anymore -- they no longer confuse GDB.
2898 (som_begin_writing): Leave space for an exec header if writing
2900 (som_slurp_symbol_table): Recognize both forms of section symbol
2901 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2902 section symbols to be the name of the section they represent.
2903 Debugging symbols begin with "L$0\001", not just "L$".
2905 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2907 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2909 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2910 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2911 and bfd_is_local_label.
2913 * targets.c: Add new entries to the bfd_target structure.
2915 * bfd.c (bfd_copy_private_bfd_data): New definition.
2917 * section.c (bfd_copy_private_section_data): New definition.
2919 * syms.c (bfd_is_local_label): New definition.
2921 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2923 * libbfd.c (bfd_generic_is_local_label): New function.
2925 * *-core.c: Provide default definitions for new functions in
2926 the target vector which all point to bfd_false.
2928 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2929 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2930 Default new vectors for copying private backend data to bfd_true.
2931 Default new vector for determining if a symbol is a local label
2932 to bfd_generic_is_local_label.
2934 * som.c (som_bfd_copy_private_section_data): New function.
2935 (som_bfd_is_local_label): New function.
2936 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2938 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2940 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2942 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2944 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2947 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2948 Indent some of them to GNU standards.
2950 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2951 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2952 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2953 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2954 Update copyright years.
2956 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2958 * som.c (som_prep_for_fixups): A relocation involving the section
2959 symbol for the *ABS* section is really a relocation involving
2961 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2962 undefined symbols. Correctly distinguish between debugger symbols
2963 and section symbols.
2965 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2966 for spaces and subspaces.
2968 * som.c (som_bfd_count_ar_symbols): Fix typo.
2970 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2971 HAS_RELOC based on the object's magic number.
2972 (make_unique_section): Delete function. BFD and its users are
2973 prepared to handle multiple sections with the same name.
2974 (setup_sections): Allocate space on the BFD's obstack to hold
2975 section names. Use bfd_make_setion_anyway rather than the
2976 obsolete make_unique_section.
2977 (som_prep_headers): Choose the correct SOM magic number based
2979 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2981 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2983 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2984 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.

2991 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2993 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2994 is always located at the start of the data section to allow
2995 recovery of the dynamic info from a stripped executable.
2996 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2999 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3001 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3002 cruft (like the #pragma alloca for AIX).
3003 In addition to that problem, the C alloca calls xmalloc, which
3004 means checking for being out of memory can't work right. The
3005 following changes remove all uses of alloca from BFD.
3006 * hosts/solaris2.h: Remove alloca cruft.
3007 * som.c: Replace alloca with a fixed size auto array.
3008 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

3012 * linker.c: Replace alloca with obstack_alloc.
3013 * libbfd.h: Rebuilt.
3015 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3017 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3020 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3022 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3023 Elf*_Off typedefs by their expansion, the typedefs have been
3024 removed from include/elf/internal.h.
3025 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3026 SHT_PROGBITS section.

3356 bother processing them.
3357 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4060 The sparc (and possibly other?) NLM format requires a different
4061 way to write exports, so add a write_export field to the backend
4062 data (and set it to NULL for everything but the sparc).
