2599 required by expansions. Set s and unset h when converting a reloc
2600 from undefined to section. Change handling of PC relative relocs:
2601 if against a section, they are correct in the object file, if
2602 against an external symbol they are pcrel_offset.

2732 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2734 Support for link_order types which generate relocs in order to
2735 support -Ur in the linker.
2736 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2737 from call to _bfd_generic_link_add_one_symbol.
2738 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2739 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2740 instead of bitsize to add_to_set call back.
2741 (_bfd_generic_final_link): Account for link_order relocs when
2742 allocating space for relocations. Handle them in link_order loop.
2743 (_bfd_generic_reloc_link_order): New function.

2761 allocating space for relocations. Handle them in link_order loop.
2762 (ecoff_link_write_external): Set the storage class of a defined
2763 linker created symbol based on the section it is in. Correct
2764 bfd_link_hash_weak case to use .sc rather than .st.
2765 (ecoff_reloc_link_order): New function.
2766 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

2782 comparison for function symbols within executables.
2784 * som.c (bfd_section_from_som_symbol): Renamed from
2785 som_section_from_subspace_index. Pass in a native SOM symbol.
2786 For executables, iterate through the sections to find out
2787 which contains the symbol's address rather than using the
2788 symbol_info field. (symbol_info has a different meaning for
2789 dynamicly linked executables.)
2791 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2794 * som.c (som_begin_writing): Fix braino (one call to align
2795 space/subspace data was done unconditionally rather than
2796 just for executables.)
2798 * som.c (som_begin_writing): Align text in all executables to
2799 make HPUX kernel happy. Fixes strip/objcopy for shared
2802 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2804 * som.c (som_begin_writing): Account for alignment needs of
2805 subspaces too when writing executables. Never request a negative
2806 bss size. Fixes some problems with demand paged executables,
2807 still having problems with pure executables and shared executables.
2809 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2811 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2812 bfd_zalloc for rawptr, because later on we may call free, not
2815 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2816 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2817 * cisco-core.c: New file.

2824 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2826 * som.h (som_copyable_section_data_struct): New structure
2827 containing all the private section information which needs
2828 to be copied from input section to output section during
2830 (som_section_data_struct): Remove several fields now in
2831 som_copyable_section_data_struct. Make the space and
2832 subspace dictionaries be pointers (to save space when
2833 only reading objects).
2835 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2836 some references changed. Allocate a copyable data stucture if
2837 none exists. Store info into the copyable data structure.
2838 (bfd_som_set_subsection_attributes): Likewise.
2839 (som_is_space, som_is_subspace, som_is_container): New functions.
2840 Use these instead of directly accessing private data.
2841 (som_prep_headers): Allocate space and subspace headers here.
2842 Fill in some fields in the space/subspace headers from the
2844 (som_bfd_copy_private_section_data): Only copy the stuff
2845 that we really need to make objcopy and strip work. Allocate
2846 the copy_data structure for the output bfd before copying.
2848 * som.h (struct som_exec_data): New structure to hold exec
2849 info that must be preserved when running objcopy/strip.
2850 (struct somdata): Add new "exec_data" field and accessor
2851 macro. Add some comments on how the various fields are used.
2852 (som_section_data_struct): Make is_space and is_subspace bitfields.
2853 Delete unused subspace_index. All references now use the
2854 target_index field within the section structure itself.
2856 * som.c (make_unique_section): Delete unused declaration.
2857 (som_bfd_copy_private_bfd_data): New function.
2858 (som_object_setup): Allocate space for and save exec information
2859 that needs to be copied during objcopy/strip.
2860 (som_mkobject): Do not allocate space for a file header here.
2861 It is not used when only reading SOM objects.
2862 (som_prep_headers): Allocate space for and attach a file header
2863 to the output bfd. For executables, use the saved system_id
2864 value rather than trying to guess the right value. Do not abort
2865 wwhen setting file_hdr->entry* for executables.
2866 (som_begin_writing): For executables, set the exec_entry and
2868 (som_copy_private_backend_section_data): Always return a value.
2870 * libhppa.h (PA_PAGESIZE): Define.
2872 * som.c (SOM_ALIGN): Define.
2873 (som_begin_writing): If writing an executable, initialize all
2874 fields in the exec header to zero. Update fields in the exec
2875 header as sizes of loadable subspaces are computed. Carefully
2876 preserve alignments when building executables. Actually write the
2877 exec after all the fields are filled in.
2879 * Better long-filename handling. Reads SOM ABI compliant extended
2880 names, but doesn't quite write compliant extended names yet.
2881 * som.c (som_slurp_extended_name_table): Delete function. The
2882 generic code will handle things correctly.
2883 (som_slurp_armap): Seek to the beginning of the next member.
2884 (normalize): New function.
2885 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2886 name table into account when computing the file offsets in the
2887 SOM dictionary. Make sure to align to an even boundary.
2888 (som_write_armap): Initialize the checksum to zero.
2889 (ar_maxchars): Fix. Opps.

2893 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2894 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2896 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2898 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2899 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2900 * bfd-in2.h: Regenerated.
2902 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2903 this was also named trad_unix_bfd_copy_private_bfd_data.
2905 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2907 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2908 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2909 returns NULL, it is not an error. It's possible that some of
2910 these checks are not necessary (because the size can never be
2911 zero), but putting in the checks is the conservative thing to do
2912 in light of the fact that some of these malloc calls replaced
2913 unchecked alloca calls, in which a zero argument would work fine.
2915 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2917 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2918 duplicate definition.
2919 (osf_core_bfd_is_local_label): Define.
2921 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2922 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2923 failure indication, it merely means there are no relocs.
2925 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2926 after NAME, since SunOS /bin/cc can't handle it.
2928 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2930 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2931 From sukes@glue.umd.edu (Tasuki Hirata).
2933 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2935 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2936 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2937 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2939 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2941 * som.c (som_prep_for_fixups): Detect section symbols based
2942 on either the lack of private data or the symbol flags. Do not
2943 munge section symbol names anymore -- they no longer confuse GDB.
2944 (som_begin_writing): Leave space for an exec header if writing
2946 (som_slurp_symbol_table): Recognize both forms of section symbol
2947 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2948 section symbols to be the name of the section they represent.
2949 Debugging symbols begin with "L$0\001", not just "L$".
2951 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2953 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2955 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2956 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2957 and bfd_is_local_label.
2959 * targets.c: Add new entries to the bfd_target structure.

2975 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2976 Default new vectors for copying private backend data to bfd_true.
2977 Default new vector for determining if a symbol is a local label
2978 to bfd_generic_is_local_label.
2980 * som.c (som_bfd_copy_private_section_data): New function.
2981 (som_bfd_is_local_label): New function.
2982 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2984 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2986 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2988 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2990 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2993 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2994 Indent some of them to GNU standards.
2996 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2997 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2999 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3000 Update copyright years.
3002 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3004 * som.c (som_prep_for_fixups): A relocation involving the section
3005 symbol for the *ABS* section is really a relocation involving
3007 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3008 undefined symbols. Correctly distinguish between debugger symbols
3009 and section symbols.
3011 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3012 for spaces and subspaces.
3014 * som.c (som_bfd_count_ar_symbols): Fix typo.
3016 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3017 HAS_RELOC based on the object's magic number.
3018 (make_unique_section): Delete function. BFD and its users are
3019 prepared to handle multiple sections with the same name.
3020 (setup_sections): Allocate space on the BFD's obstack to hold
3021 section names. Use bfd_make_setion_anyway rather than the
3022 obsolete make_unique_section.
3023 (som_prep_headers): Choose the correct SOM magic number based
3025 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

3048 cruft (like the #pragma alloca for AIX).
3049 In addition to that problem, the C alloca calls xmalloc, which
3050 means checking for being out of memory can't work right. The
3051 following changes remove all uses of alloca from BFD.

3400 that will actually be retained.
3401 (b_out_relax_section): If a section contains no relocations, don't
3402 bother processing them.
3403 (b_out_get_relocated_section_contents): Set reloc_done. Assert
3404 that bfd_get_section_contents returns true. Check that relocs are

3407 that reloc->addend falls between the current source offset and the
3408 raw size of the input section.

3487 Make all callers of malloc or realloc (including via obstacks)
3488 check the result for NULL. Most set bfd_error to no_memory and
3489 return in that case; a few are harder to fix, and are marked

3936 (only testing for m68k and vax at the moment); do verify that the
3937 preprocessor didn't trash the arch name inside the string version.

4079 undefined, look it up in the linker hash table.
4081 * aoutx.h (translate_symbol_table): The string index 0 has a

4106 The sparc (and possibly other?) NLM format requires a different
4107 way to write exports, so add a write_export field to the backend
4108 data (and set it to NULL for everything but the sparc).

4158 read_dynamic_relocs fields.
4159 * aout-target.h (MY(backend_data)): Initialize

4269 * ecofflink.c: Extensive changes to compress and merge debugging
4270 information, and to write some of out directly rather than saving

4274 sym_filepos as well.
4275 (ecoff_get_extr): Use ifdmap instead of ifdbase.

4345 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
4347 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

4350 * configure.in (nlm32_alpha_vec): Set target64 to true.
4352 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4353 different, so there is no point to providing a generic one.
4354 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
4355 in the backend accessor macros; that should no longer be possible.
4356 * targets.c (target_vector): Removed nlm32_big_generic_vec,
4357 nlm64_big_generic_vec, nlm64_little_generic_vec.

5245 of architectures, get the ELF EM_xxx code from the backend
5246 information. Let the generic ELF target match any EM_xxx code not
5247 matched by another ELF target. Call elf_backend_object_p to let
5248 the backend do more checks and set global information.
5249 * libelf.h (struct elf_backend_data): Added elf_machine_code and
5250 elf_backend_object_p fields.
5251 (struct bfd_elf_arch_map): Removed.

5253 * elf32-target.h, elf64-target.h: Initialize elf_machine_code
5254 field with ELF_MACHINE_CODE. Initialize elf_backend_object_p
5255 field with elf_backend_object_p (if it is defined).

5272 * elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
5273 for R_MIPS_26. Correct overflow detection requires matching the
5274 upper four bits of the destination against the PC. From Ted Lemon
5275 <mellon@pepper.ncd.com>.
5277 * bout.c (b_out_reloc_type_lookup): Return type should point to
5279 * coff-i960.c (coff_i960_reloc_type_lookup): Likewise.
5280 * elf32-hppa.c (elf_hppa_reloc_type_lookup): Likewise.

5287 field. Removed unused write_relocs field.
5288 * elf32-target.h: Adjusted elf_backend_data initialization
5290 * elf64-target.h: Corrected elf_backend_data initialization to
5291 fill in all fields and to set elf_64_p to 1.
5293 Mon Nov 8 18:13:14 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
