1 Thu Aug 18 16:29:57 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2
3 Get ld -x -r to handle a.out set symbols correctly.
4 * aoutx.h (adjust_o_magic): If the .bss VMA was set outside of
5 BFD, pad the .data section up to the VMA of the .bss section.
6 (aout_link_add_symbols): If a set symbol does not get modified,
7 treat it as a local symbol.
8 (aout_link_write_symbols): Set the value of set symbols
9 correctly. Don't discard set symbols even if discarding local
10 symbols.
11 (aout_link_write_other_symbol): Don't abort on bfd_link_hash_new,
12 since it can now happen for set symbols.
13
14 * elfcode.h (elf_fake_sections): Just check for ".rela" and
15 ".rel", not ".rela." and ".rel."; make this work by checking
16 use_rela_p.
17 * elf32-i386.c (elf_i386_check_relocs): Just check for ".rel", not
18 ".rel."
19 (elf_i386_size_dynamic_sections): Likewise.

2764 call to _bfd_generic_link_add_one_symbol.
2765 (NAME(aout,final_link)): Account for link_order relocs when
2766 allocating space for relocations. Handle them after handling all
2767 input BFDs.
2768 (aout_link_reloc_link_order): New function.
2769 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
2770 call to _bfd_generic_link_add_one_symbol.
2771 (ecoff_bfd_final_link): Account for link_order relocs when
2772 allocating space for relocations. Handle them in link_order loop.
2773 (ecoff_link_write_external): Set the storage class of a defined
2774 linker created symbol based on the section it is in. Correct
2775 bfd_link_hash_weak case to use .sc rather than .st.
2776 (ecoff_reloc_link_order): New function.
2777 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2778 BFD_RELOC_CTOR.
2779 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2780
2781 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2782 and buf.
2783
2784 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2785 bfd_zmalloc. Free a pointer, not a union.
2786 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2787
2788 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2789
2790 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2791
2792 * som.c (bfd_section_from_som_symbol): Only to do the value
2793 comparison for function symbols within executables.
2794
2795 * som.c (bfd_section_from_som_symbol): Renamed from
2796 som_section_from_subspace_index. Pass in a native SOM symbol.
2797 For executables, iterate through the sections to find out
2798 which contains the symbol's address rather than using the
2799 symbol_info field. (symbol_info has a different meaning for
2800 dynamicly linked executables.)
2801
2802 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2803 bfd_zmalloc.
2804
2805 * som.c (som_begin_writing): Fix braino (one call to align
2806 space/subspace data was done unconditionally rather than
2807 just for executables.)
2808
2809 * som.c (som_begin_writing): Align text in all executables to
2810 make HPUX kernel happy. Fixes strip/objcopy for shared
2811 executables.
2812
2813 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2814
2815 * som.c (som_begin_writing): Account for alignment needs of
2816 subspaces too when writing executables. Never request a negative
2817 bss size. Fixes some problems with demand paged executables,
2818 still having problems with pure executables and shared executables.
2819
2820 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2821
2822 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2823 bfd_zalloc for rawptr, because later on we may call free, not
2824 bfd_release, on it.
2825
2826 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2827 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2828 * cisco-core.c: New file.
2829 * Makefile.in: Change accordingly.
2830 * configure.in: Recognize cisco_core_vec.
2831 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2832 * targets.c: Add cisco_core_vec.
2833 * bfd-in2.h: Rebuilt.
2834
2835 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2836
2837 * som.h (som_copyable_section_data_struct): New structure
2838 containing all the private section information which needs
2839 to be copied from input section to output section during
2840 objcopy or strip.
2841 (som_section_data_struct): Remove several fields now in
2842 som_copyable_section_data_struct. Make the space and
2843 subspace dictionaries be pointers (to save space when
2844 only reading objects).
2845
2846 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2847 some references changed. Allocate a copyable data stucture if
2848 none exists. Store info into the copyable data structure.
2849 (bfd_som_set_subsection_attributes): Likewise.
2850 (som_is_space, som_is_subspace, som_is_container): New functions.
2851 Use these instead of directly accessing private data.
2852 (som_prep_headers): Allocate space and subspace headers here.
2853 Fill in some fields in the space/subspace headers from the
2854 copyable data.
2855 (som_bfd_copy_private_section_data): Only copy the stuff
2856 that we really need to make objcopy and strip work. Allocate
2857 the copy_data structure for the output bfd before copying.
2858
2859 * som.h (struct som_exec_data): New structure to hold exec
2860 info that must be preserved when running objcopy/strip.
2861 (struct somdata): Add new "exec_data" field and accessor
2862 macro. Add some comments on how the various fields are used.
2863 (som_section_data_struct): Make is_space and is_subspace bitfields.
2864 Delete unused subspace_index. All references now use the
2865 target_index field within the section structure itself.
2866
2867 * som.c (make_unique_section): Delete unused declaration.
2868 (som_bfd_copy_private_bfd_data): New function.
2869 (som_object_setup): Allocate space for and save exec information
2870 that needs to be copied during objcopy/strip.
2871 (som_mkobject): Do not allocate space for a file header here.
2872 It is not used when only reading SOM objects.
2873 (som_prep_headers): Allocate space for and attach a file header
2874 to the output bfd. For executables, use the saved system_id
2875 value rather than trying to guess the right value. Do not abort
2876 wwhen setting file_hdr->entry* for executables.
2877 (som_begin_writing): For executables, set the exec_entry and
2878 exec_flags fields.
2879 (som_copy_private_backend_section_data): Always return a value.
2880
2881 * libhppa.h (PA_PAGESIZE): Define.
2882
2883 * som.c (SOM_ALIGN): Define.
2884 (som_begin_writing): If writing an executable, initialize all
2885 fields in the exec header to zero. Update fields in the exec
2886 header as sizes of loadable subspaces are computed. Carefully
2887 preserve alignments when building executables. Actually write the
2888 exec after all the fields are filled in.
2889
2890 * Better long-filename handling. Reads SOM ABI compliant extended
2891 names, but doesn't quite write compliant extended names yet.
2892 * som.c (som_slurp_extended_name_table): Delete function. The
2893 generic code will handle things correctly.
2894 (som_slurp_armap): Seek to the beginning of the next member.
2895 (normalize): New function.
2896 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2897 name table into account when computing the file offsets in the
2898 SOM dictionary. Make sure to align to an even boundary.
2899 (som_write_armap): Initialize the checksum to zero.
2900 (ar_maxchars): Fix. Opps.
2901
2902 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2903
2904 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2905 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2906
2907 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2908
2909 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2910 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2911 * bfd-in2.h: Regenerated.
2912
2913 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2914 this was also named trad_unix_bfd_copy_private_bfd_data.
2915
2916 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2917
2918 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2919 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2920 returns NULL, it is not an error. It's possible that some of
2921 these checks are not necessary (because the size can never be
2922 zero), but putting in the checks is the conservative thing to do
2923 in light of the fact that some of these malloc calls replaced
2924 unchecked alloca calls, in which a zero argument would work fine.
2925
2926 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2927
2928 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2929 duplicate definition.
2930 (osf_core_bfd_is_local_label): Define.
2931
2932 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2933 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2934 failure indication, it merely means there are no relocs.
2935
2936 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2937 after NAME, since SunOS /bin/cc can't handle it.
2938
2939 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2940
2941 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2942 From sukes@glue.umd.edu (Tasuki Hirata).
2943
2944 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2945
2946 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2947 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2948 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2949
2950 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2951
2952 * som.c (som_prep_for_fixups): Detect section symbols based
2953 on either the lack of private data or the symbol flags. Do not
2954 munge section symbol names anymore -- they no longer confuse GDB.
2955 (som_begin_writing): Leave space for an exec header if writing
2956 an executable.
2957 (som_slurp_symbol_table): Recognize both forms of section symbol
2958 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2959 section symbols to be the name of the section they represent.
2960 Debugging symbols begin with "L$0\001", not just "L$".
2961
2962 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2963
2964 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2965
2966 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2967 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2968 and bfd_is_local_label.
2969
2970 * targets.c: Add new entries to the bfd_target structure.
2971
2972 * bfd.c (bfd_copy_private_bfd_data): New definition.
2973
2974 * section.c (bfd_copy_private_section_data): New definition.
2975
2976 * syms.c (bfd_is_local_label): New definition.
2977
2978 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2979
2980 * libbfd.c (bfd_generic_is_local_label): New function.
2981
2982 * *-core.c: Provide default definitions for new functions in
2983 the target vector which all point to bfd_false.
2984
2985 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2986 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2987 Default new vectors for copying private backend data to bfd_true.
2988 Default new vector for determining if a symbol is a local label
2989 to bfd_generic_is_local_label.
2990
2991 * som.c (som_bfd_copy_private_section_data): New function.
2992 (som_bfd_is_local_label): New function.
2993 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2994
2995 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2996
2997 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2998
2999 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3000
3001 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3002
3003 * Most files:
3004 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3005 Indent some of them to GNU standards.
3006
3007 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3008 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3009 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3010 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3011 Update copyright years.
3012
3013 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3014
3015 * som.c (som_prep_for_fixups): A relocation involving the section
3016 symbol for the *ABS* section is really a relocation involving
3017 no symbol.
3018 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3019 undefined symbols. Correctly distinguish between debugger symbols
3020 and section symbols.
3021
3022 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3023 for spaces and subspaces.
3024
3025 * som.c (som_bfd_count_ar_symbols): Fix typo.
3026
3027 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3028 HAS_RELOC based on the object's magic number.
3029 (make_unique_section): Delete function. BFD and its users are
3030 prepared to handle multiple sections with the same name.
3031 (setup_sections): Allocate space on the BFD's obstack to hold
3032 section names. Use bfd_make_setion_anyway rather than the
3033 obsolete make_unique_section.
3034 (som_prep_headers): Choose the correct SOM magic number based
3035 on the BFD's flags.
3036 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3037
3038 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3039
3040 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3041 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3042 * Makefile.in, configure.in: Corresponding changes.
3043
3044 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3045
3046 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3047
3048 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3049
3050 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3051 is always located at the start of the data section to allow
3052 recovery of the dynamic info from a stripped executable.
3053 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3054 and STYP_COMMENT.
3055
3056 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3057
3058 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3059 cruft (like the #pragma alloca for AIX).
3060 In addition to that problem, the C alloca calls xmalloc, which
3061 means checking for being out of memory can't work right. The
3062 following changes remove all uses of alloca from BFD.
3063 * hosts/solaris2.h: Remove alloca cruft.
3064 * som.c: Replace alloca with a fixed size auto array.
3065 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3066 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3067 sunos.c: Replace alloca with malloc and appropriate error checking and
3068 freeing.
3069 * linker.c: Replace alloca with obstack_alloc.
3070 * libbfd.h: Rebuilt.
3071
3072 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3073
3074 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3075 MIPS_R_GPREL.
3076
3077 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3078
3079 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3080 Elf*_Off typedefs by their expansion, the typedefs have been
3081 removed from include/elf/internal.h.
3082 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3083 SHT_PROGBITS section.
3084
3085 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3086
3087 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
3088
3089 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3090
3091 * configure.host: Recognize i[34]86-sequent-*.
3092
3093 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3094 return from bfd_seek indicates an error.
3095 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3096 TRAD_CORE_STACK_OFFSET.
3097 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3098 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3099
3100 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3101
3102 * som.[ch]: Do not include libhppa.h in som.c, instead include
3103 it in som.h.
3104
3105 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3106 include it in elf32-hppa.h.
3107
3108 * som.c (log2): Return -1 on error rather than aborting.
3109 (setup_sections): Bubble up an error from log2.
3110
3111 * Changes to make HP C compiler happy in both traditional
3112 and ANSI mode.
3113 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3114 field parameter.
3115 (bfd_som_set_section_attributes): Use unsigned int rather than
3116 unsigned char to avoid GNU-C extensions.
3117 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3118 or failure rather than aborting on failure.
3119
3120 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3121 som.c changes.
3122 (bfd_som_attach_aux_hdr): Add prototype.
3123 (hppa_som-gen_reloc_type): Likewise.
3124
3125 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3126 (hppa_look_for_stubs_in_section): Do not return false on failure
3127 until rest of code is ready to handle it. Abort for now.
3128
3129 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3130
3131 * bfd-in2.h: Rebuilt.
3132
3133 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
3134
3135 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
3136 * Makefile.in: delete an extra blank.
3137 * configure.in : Add i396os9k_vec.
3138
3139 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
3140
3141 * config.bfd : Add i386-os9k.
3142 * config/i386-os9k.mt : Newly add os9k target makefile.
3143
3144 * i386os9k.c : new file to handle os9k format bfd.
3145 * Makefile.in : Handle new file i386os9k.c
3146 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
3147 * cache.c : Initialize cache_sentinel to 0.
3148
3149 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3150
3151 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
3152 action in case where caller specified no argument relocation.
3153 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3154 right in the original relocation and the stub's relocation.
3155
3156 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3157 unused symbols argument.
3158
3159 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3160 than asymbol * for original target symbol. All callers changed.
3161 Set reloc->sym_ptr_ptr appropriately.
3162 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3163 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3164 argument. Use the output symbols when canonicalizing the relocs,
3165 creating them if necessary.
3166

3182 PARAMize and staticize rest of functions. Delete unused
3183 functions. Delete unused/unnecessary arguments to some functions.

3185 error code propogation working. Work on spacing and indention.
3186 Add FIXMEs for unresolved problems. Use enums rather than
3187 #defines for lots of things. Merge two functions which build
3188 linker stubs into a single function (so they can easily share a
3189 ton of common code).

3232 static vars together. Collapse common case statements together
3233 in many places. Use default case when possible instead of listing
3234 each case separately. Abort for bad errors until we get error
3235 code propogation working. Work on spacing and indention problems.
3236 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3237 COMPLEX relocation support (it's never used anyway).
3238 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3399 * section.c (bfd_get_section_contents): Since this function reads
3400 unrelocated contents, the section's raw size is always the one to
3401 use for bounds checking.

3419 raw size of the input section.
3420
3421 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
3422 bout. Default with no version number is still bout. Support

3498 Make all callers of malloc or realloc (including via obstacks)
3499 check the result for NULL. Most set bfd_error to no_memory and

4065 get the index of a common section, rather than always using
4066 SHN_COMMON (MIPS has multiple common sections).
4067
4068 * elf32-hppa.c (hppa_elf_gen_reloc_type): Typo (== for =).

4163 return value.
4164 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
4165 out dynamic symbols or relocs against reloc symbols, since they
4166 are already in the .text section and we wouldn't know where to
4167 write them anyhow.
4168 (sunos4_aout_backend): Initialize read_dynamic_symbols and
4169 read_dynamic_relocs fields.

4351
4352 * nlmcode.h (nlm_object_p): If we can't read the fixed header,

4357 BFD64.
4358 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.
