2594 * aoutx.h (NAME(aout,find_nearest_line)): The caller expects
2595 functionname_ptr to be set to a symbol name, so prepend
2596 symbol_leading_char.

2670 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2672 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2673 reloc, used in embedded PIC code.
2674 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2693 _bfd_generic_link_add_symbols but also collect constructors and
2694 destructors by name as collect2 does.
2695 (generic_link_add_symbols): New function, like old
2696 _bfd_generic_link_add_symbols but with collect argument.

2713 extended name table.
2715 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2717 Support for link_order types which generate relocs in order to
2718 support -Ur in the linker.
2719 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2720 from call to _bfd_generic_link_add_one_symbol.
2721 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2722 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2723 instead of bitsize to add_to_set call back.
2724 (_bfd_generic_final_link): Account for link_order relocs when
2725 allocating space for relocations. Handle them in link_order loop.
2726 (_bfd_generic_reloc_link_order): New function.

2744 allocating space for relocations. Handle them in link_order loop.
2745 (ecoff_link_write_external): Set the storage class of a defined
2746 linker created symbol based on the section it is in. Correct
2747 bfd_link_hash_weak case to use .sc rather than .st.

2760 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2762 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2764 * som.c (bfd_section_from_som_symbol): Only to do the value
2765 comparison for function symbols within executables.
2767 * som.c (bfd_section_from_som_symbol): Renamed from
2768 som_section_from_subspace_index. Pass in a native SOM symbol.
2769 For executables, iterate through the sections to find out
2770 which contains the symbol's address rather than using the
2771 symbol_info field. (symbol_info has a different meaning for
2772 dynamicly linked executables.)
2774 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2777 * som.c (som_begin_writing): Fix braino (one call to align
2778 space/subspace data was done unconditionally rather than
2779 just for executables.)
2781 * som.c (som_begin_writing): Align text in all executables to
2782 make HPUX kernel happy. Fixes strip/objcopy for shared
2785 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2787 * som.c (som_begin_writing): Account for alignment needs of
2788 subspaces too when writing executables. Never request a negative
2789 bss size. Fixes some problems with demand paged executables,
2790 still having problems with pure executables and shared executables.
2792 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2794 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2795 bfd_zalloc for rawptr, because later on we may call free, not
2798 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2799 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2800 * cisco-core.c: New file.
2801 * Makefile.in: Change accordingly.
2802 * configure.in: Recognize cisco_core_vec.
2803 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2804 * targets.c: Add cisco_core_vec.
2805 * bfd-in2.h: Rebuilt.
2807 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2809 * som.h (som_copyable_section_data_struct): New structure
2810 containing all the private section information which needs
2811 to be copied from input section to output section during
2813 (som_section_data_struct): Remove several fields now in
2814 som_copyable_section_data_struct. Make the space and
2815 subspace dictionaries be pointers (to save space when
2816 only reading objects).
2818 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2819 some references changed. Allocate a copyable data stucture if
2820 none exists. Store info into the copyable data structure.
2821 (bfd_som_set_subsection_attributes): Likewise.
2822 (som_is_space, som_is_subspace, som_is_container): New functions.
2823 Use these instead of directly accessing private data.
2824 (som_prep_headers): Allocate space and subspace headers here.
2825 Fill in some fields in the space/subspace headers from the
2827 (som_bfd_copy_private_section_data): Only copy the stuff
2828 that we really need to make objcopy and strip work. Allocate
2829 the copy_data structure for the output bfd before copying.
2831 * som.h (struct som_exec_data): New structure to hold exec
2832 info that must be preserved when running objcopy/strip.
2833 (struct somdata): Add new "exec_data" field and accessor
2834 macro. Add some comments on how the various fields are used.
2835 (som_section_data_struct): Make is_space and is_subspace bitfields.
2836 Delete unused subspace_index. All references now use the
2837 target_index field within the section structure itself.
2839 * som.c (make_unique_section): Delete unused declaration.
2840 (som_bfd_copy_private_bfd_data): New function.
2841 (som_object_setup): Allocate space for and save exec information
2842 that needs to be copied during objcopy/strip.
2843 (som_mkobject): Do not allocate space for a file header here.
2844 It is not used when only reading SOM objects.
2845 (som_prep_headers): Allocate space for and attach a file header
2846 to the output bfd. For executables, use the saved system_id
2847 value rather than trying to guess the right value. Do not abort
2848 wwhen setting file_hdr->entry* for executables.
2849 (som_begin_writing): For executables, set the exec_entry and
2851 (som_copy_private_backend_section_data): Always return a value.
2853 * libhppa.h (PA_PAGESIZE): Define.
2855 * som.c (SOM_ALIGN): Define.
2856 (som_begin_writing): If writing an executable, initialize all
2857 fields in the exec header to zero. Update fields in the exec
2858 header as sizes of loadable subspaces are computed. Carefully
2859 preserve alignments when building executables. Actually write the
2860 exec after all the fields are filled in.
2862 * Better long-filename handling. Reads SOM ABI compliant extended
2863 names, but doesn't quite write compliant extended names yet.
2864 * som.c (som_slurp_extended_name_table): Delete function. The
2865 generic code will handle things correctly.
2866 (som_slurp_armap): Seek to the beginning of the next member.
2867 (normalize): New function.
2868 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2869 name table into account when computing the file offsets in the
2870 SOM dictionary. Make sure to align to an even boundary.
2871 (som_write_armap): Initialize the checksum to zero.
2872 (ar_maxchars): Fix. Opps.
2874 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2876 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2877 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2879 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2881 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2882 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2883 * bfd-in2.h: Regenerated.
2885 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2886 this was also named trad_unix_bfd_copy_private_bfd_data.
2888 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2890 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2891 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2892 returns NULL, it is not an error. It's possible that some of
2893 these checks are not necessary (because the size can never be
2894 zero), but putting in the checks is the conservative thing to do
2895 in light of the fact that some of these malloc calls replaced
2896 unchecked alloca calls, in which a zero argument would work fine.
2898 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2900 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2901 duplicate definition.
2902 (osf_core_bfd_is_local_label): Define.
2904 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2905 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2906 failure indication, it merely means there are no relocs.
2908 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2909 after NAME, since SunOS /bin/cc can't handle it.
2911 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2913 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2914 From sukes@glue.umd.edu (Tasuki Hirata).
2916 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2918 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2919 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2920 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2922 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2924 * som.c (som_prep_for_fixups): Detect section symbols based
2925 on either the lack of private data or the symbol flags. Do not
2926 munge section symbol names anymore -- they no longer confuse GDB.
2927 (som_begin_writing): Leave space for an exec header if writing
2929 (som_slurp_symbol_table): Recognize both forms of section symbol
2930 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2931 section symbols to be the name of the section they represent.
2932 Debugging symbols begin with "L$0\001", not just "L$".
2934 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2936 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2938 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2939 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2940 and bfd_is_local_label.
2942 * targets.c: Add new entries to the bfd_target structure.
2944 * bfd.c (bfd_copy_private_bfd_data): New definition.
2946 * section.c (bfd_copy_private_section_data): New definition.

2950 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2952 * libbfd.c (bfd_generic_is_local_label): New function.
2954 * *-core.c: Provide default definitions for new functions in
2955 the target vector which all point to bfd_false.
2957 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2958 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2959 Default new vectors for copying private backend data to bfd_true.
2960 Default new vector for determining if a symbol is a local label
2961 to bfd_generic_is_local_label.
2963 * som.c (som_bfd_copy_private_section_data): New function.
2964 (som_bfd_is_local_label): New function.
2965 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2967 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2969 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2971 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2973 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2976 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2977 Indent some of them to GNU standards.
2979 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2980 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2981 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2982 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2983 Update copyright years.
2985 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2987 * som.c (som_prep_for_fixups): A relocation involving the section
2988 symbol for the *ABS* section is really a relocation involving
2990 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2991 undefined symbols. Correctly distinguish between debugger symbols
2992 and section symbols.
2994 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2995 for spaces and subspaces.
2997 * som.c (som_bfd_count_ar_symbols): Fix typo.
2999 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3000 HAS_RELOC based on the object's magic number.
3001 (make_unique_section): Delete function. BFD and its users are
3002 prepared to handle multiple sections with the same name.
3003 (setup_sections): Allocate space on the BFD's obstack to hold
3004 section names. Use bfd_make_setion_anyway rather than the
3005 obsolete make_unique_section.
3006 (som_prep_headers): Choose the correct SOM magic number based
3008 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3010 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3012 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3013 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3014 * Makefile.in, configure.in: Corresponding changes.
3016 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3018 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3020 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3022 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3023 is always located at the start of the data section to allow
3024 recovery of the dynamic info from a stripped executable.
3025 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3028 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3030 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3031 cruft (like the #pragma alloca for AIX).
3032 In addition to that problem, the C alloca calls xmalloc, which
3033 means checking for being out of memory can't work right. The

3385 bother processing them.
3386 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3470 Make all callers of malloc or realloc (including via obstacks)
3471 check the result for NULL. Most set bfd_error to no_memory and

3892 * coff-mips.c (mips_ecoff_backend_data), coff-alpha.c
3893 (alpha_ecoff_backend_data): Change casts of aux_in and aux_out

4089 The sparc (and possibly other?) NLM format requires a different
4090 way to write exports, so add a write_export field to the backend
4091 data (and set it to NULL for everything but the sparc).

4257 sym_filepos as well.
4258 (ecoff_get_extr): Use ifdmap instead of ifdbase.

4330 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

4335 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4336 different, so there is no point to providing a generic one.
4337 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
4338 in the backend accessor macros; that should no longer be possible.
