2649 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2651 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2652 reloc, used in embedded PIC code.

2672 _bfd_generic_link_add_symbols but also collect constructors and
2673 destructors by name as collect2 does.

2692 extended name table.
2694 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2696 Support for link_order types which generate relocs in order to
2697 support -Ur in the linker.
2698 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2699 from call to _bfd_generic_link_add_one_symbol.
2700 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2701 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2702 instead of bitsize to add_to_set call back.
2703 (_bfd_generic_final_link): Account for link_order relocs when
2704 allocating space for relocations. Handle them in link_order loop.
2705 (_bfd_generic_reloc_link_order): New function.

2723 allocating space for relocations. Handle them in link_order loop.
2724 (ecoff_link_write_external): Set the storage class of a defined
2725 linker created symbol based on the section it is in. Correct
2726 bfd_link_hash_weak case to use .sc rather than .st.

2743 * som.c (bfd_section_from_som_symbol): Only to do the value
2744 comparison for function symbols within executables.
2746 * som.c (bfd_section_from_som_symbol): Renamed from
2747 som_section_from_subspace_index. Pass in a native SOM symbol.
2748 For executables, iterate through the sections to find out
2749 which contains the symbol's address rather than using the
2750 symbol_info field. (symbol_info has a different meaning for
2751 dynamicly linked executables.)
2753 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2756 * som.c (som_begin_writing): Fix braino (one call to align
2757 space/subspace data was done unconditionally rather than
2758 just for executables.)
2760 * som.c (som_begin_writing): Align text in all executables to
2761 make HPUX kernel happy. Fixes strip/objcopy for shared
2764 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2766 * som.c (som_begin_writing): Account for alignment needs of
2767 subspaces too when writing executables. Never request a negative
2768 bss size. Fixes some problems with demand paged executables,
2769 still having problems with pure executables and shared executables.
2771 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2773 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2774 bfd_zalloc for rawptr, because later on we may call free, not
2777 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2778 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2779 * cisco-core.c: New file.
2780 * Makefile.in: Change accordingly.
2781 * configure.in: Recognize cisco_core_vec.
2782 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2783 * targets.c: Add cisco_core_vec.
2784 * bfd-in2.h: Rebuilt.
2786 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2788 * som.h (som_copyable_section_data_struct): New structure
2789 containing all the private section information which needs
2790 to be copied from input section to output section during
2792 (som_section_data_struct): Remove several fields now in
2793 som_copyable_section_data_struct. Make the space and
2794 subspace dictionaries be pointers (to save space when
2795 only reading objects).
2797 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2798 some references changed. Allocate a copyable data stucture if
2799 none exists. Store info into the copyable data structure.
2800 (bfd_som_set_subsection_attributes): Likewise.
2801 (som_is_space, som_is_subspace, som_is_container): New functions.
2802 Use these instead of directly accessing private data.
2803 (som_prep_headers): Allocate space and subspace headers here.
2804 Fill in some fields in the space/subspace headers from the
2806 (som_bfd_copy_private_section_data): Only copy the stuff
2807 that we really need to make objcopy and strip work. Allocate
2808 the copy_data structure for the output bfd before copying.
2810 * som.h (struct som_exec_data): New structure to hold exec
2811 info that must be preserved when running objcopy/strip.
2812 (struct somdata): Add new "exec_data" field and accessor
2813 macro. Add some comments on how the various fields are used.
2814 (som_section_data_struct): Make is_space and is_subspace bitfields.
2815 Delete unused subspace_index. All references now use the
2816 target_index field within the section structure itself.
2818 * som.c (make_unique_section): Delete unused declaration.
2819 (som_bfd_copy_private_bfd_data): New function.
2820 (som_object_setup): Allocate space for and save exec information
2821 that needs to be copied during objcopy/strip.
2822 (som_mkobject): Do not allocate space for a file header here.
2823 It is not used when only reading SOM objects.
2824 (som_prep_headers): Allocate space for and attach a file header
2825 to the output bfd. For executables, use the saved system_id
2826 value rather than trying to guess the right value. Do not abort
2827 wwhen setting file_hdr->entry* for executables.
2828 (som_begin_writing): For executables, set the exec_entry and
2830 (som_copy_private_backend_section_data): Always return a value.
2832 * libhppa.h (PA_PAGESIZE): Define.
2834 * som.c (SOM_ALIGN): Define.
2835 (som_begin_writing): If writing an executable, initialize all
2836 fields in the exec header to zero. Update fields in the exec
2837 header as sizes of loadable subspaces are computed. Carefully
2838 preserve alignments when building executables. Actually write the
2839 exec after all the fields are filled in.
2841 * Better long-filename handling. Reads SOM ABI compliant extended
2842 names, but doesn't quite write compliant extended names yet.
2843 * som.c (som_slurp_extended_name_table): Delete function. The
2844 generic code will handle things correctly.
2845 (som_slurp_armap): Seek to the beginning of the next member.
2846 (normalize): New function.
2847 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2848 name table into account when computing the file offsets in the
2849 SOM dictionary. Make sure to align to an even boundary.
2850 (som_write_armap): Initialize the checksum to zero.
2851 (ar_maxchars): Fix. Opps.
2853 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2855 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2856 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2858 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2860 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2861 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2862 * bfd-in2.h: Regenerated.
2864 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2865 this was also named trad_unix_bfd_copy_private_bfd_data.
2867 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2869 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2870 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2871 returns NULL, it is not an error. It's possible that some of
2872 these checks are not necessary (because the size can never be
2873 zero), but putting in the checks is the conservative thing to do
2874 in light of the fact that some of these malloc calls replaced
2875 unchecked alloca calls, in which a zero argument would work fine.
2877 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2879 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2880 duplicate definition.
2881 (osf_core_bfd_is_local_label): Define.
2883 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2884 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2885 failure indication, it merely means there are no relocs.
2887 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2888 after NAME, since SunOS /bin/cc can't handle it.
2890 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2892 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2893 From sukes@glue.umd.edu (Tasuki Hirata).
2895 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2897 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2898 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2899 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2901 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2903 * som.c (som_prep_for_fixups): Detect section symbols based
2904 on either the lack of private data or the symbol flags. Do not
2905 munge section symbol names anymore -- they no longer confuse GDB.
2906 (som_begin_writing): Leave space for an exec header if writing
2908 (som_slurp_symbol_table): Recognize both forms of section symbol
2909 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2910 section symbols to be the name of the section they represent.
2911 Debugging symbols begin with "L$0\001", not just "L$".
2913 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2915 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2917 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2918 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2919 and bfd_is_local_label.
2921 * targets.c: Add new entries to the bfd_target structure.
2923 * bfd.c (bfd_copy_private_bfd_data): New definition.
2925 * section.c (bfd_copy_private_section_data): New definition.
2927 * syms.c (bfd_is_local_label): New definition.
2929 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2931 * libbfd.c (bfd_generic_is_local_label): New function.
2933 * *-core.c: Provide default definitions for new functions in
2934 the target vector which all point to bfd_false.
2936 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2937 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2938 Default new vectors for copying private backend data to bfd_true.
2939 Default new vector for determining if a symbol is a local label
2940 to bfd_generic_is_local_label.
2942 * som.c (som_bfd_copy_private_section_data): New function.
2943 (som_bfd_is_local_label): New function.
2944 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2946 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2948 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2950 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2952 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2955 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2956 Indent some of them to GNU standards.
2958 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2959 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2960 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2961 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2962 Update copyright years.
2964 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2966 * som.c (som_prep_for_fixups): A relocation involving the section
2967 symbol for the *ABS* section is really a relocation involving
2969 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2970 undefined symbols. Correctly distinguish between debugger symbols
2971 and section symbols.
2973 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2974 for spaces and subspaces.
2976 * som.c (som_bfd_count_ar_symbols): Fix typo.
2978 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2979 HAS_RELOC based on the object's magic number.
2980 (make_unique_section): Delete function. BFD and its users are
2981 prepared to handle multiple sections with the same name.
2982 (setup_sections): Allocate space on the BFD's obstack to hold
2983 section names. Use bfd_make_setion_anyway rather than the
2984 obsolete make_unique_section.
2985 (som_prep_headers): Choose the correct SOM magic number based
2987 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2989 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2991 * elf32-ppc.c: Renamed from elf32-powerpc.c.

3001 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3002 is always located at the start of the data section to allow
3003 recovery of the dynamic info from a stripped executable.
3004 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3007 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3009 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3010 cruft (like the #pragma alloca for AIX).
3011 In addition to that problem, the C alloca calls xmalloc, which
3012 means checking for being out of memory can't work right. The
3013 following changes remove all uses of alloca from BFD.
3014 * hosts/solaris2.h: Remove alloca cruft.
3015 * som.c: Replace alloca with a fixed size auto array.
3016 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

3020 * linker.c: Replace alloca with obstack_alloc.
3021 * libbfd.h: Rebuilt.
3023 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3025 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3028 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3030 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,

4068 The sparc (and possibly other?) NLM format requires a different
4069 way to write exports, so add a write_export field to the backend
4070 data (and set it to NULL for everything but the sparc).

4236 sym_filepos as well.
4237 (ecoff_get_extr): Use ifdmap instead of ifdbase.

4314 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4315 different, so there is no point to providing a generic one.
