3016 allocating space for relocations. Handle them in link_order loop.
3017 (_bfd_generic_reloc_link_order): New function.
3018 (_bfd_default_link_order): If a reloc_link_order is seen here,
3020 (_bfd_count_link_order_relocs): New function.
3021 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3022 argument from declaration.
3023 (_bfd_generic_reloc_link_order): Declare.
3024 (_bfd_count_link_order_relocs): Declare.
3025 * libbfd.h: Rebuilt.
3026 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3027 call to _bfd_generic_link_add_one_symbol.
3028 (NAME(aout,final_link)): Account for link_order relocs when
3029 allocating space for relocations. Handle them after handling all
3031 (aout_link_reloc_link_order): New function.
3032 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
3033 call to _bfd_generic_link_add_one_symbol.
3034 (ecoff_bfd_final_link): Account for link_order relocs when
3035 allocating space for relocations. Handle them in link_order loop.
3036 (ecoff_link_write_external): Set the storage class of a defined
3037 linker created symbol based on the section it is in. Correct
3038 bfd_link_hash_weak case to use .sc rather than .st.
3039 (ecoff_reloc_link_order): New function.
3040 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3042 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
3044 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
3047 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3048 bfd_zmalloc. Free a pointer, not a union.
3049 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3051 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3053 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3055 * som.c (bfd_section_from_som_symbol): Only to do the value
3056 comparison for function symbols within executables.
3058 * som.c (bfd_section_from_som_symbol): Renamed from
3059 som_section_from_subspace_index. Pass in a native SOM symbol.
3060 For executables, iterate through the sections to find out
3061 which contains the symbol's address rather than using the
3062 symbol_info field. (symbol_info has a different meaning for
3063 dynamicly linked executables.)
3065 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3068 * som.c (som_begin_writing): Fix braino (one call to align
3069 space/subspace data was done unconditionally rather than
3070 just for executables.)
3072 * som.c (som_begin_writing): Align text in all executables to
3073 make HPUX kernel happy. Fixes strip/objcopy for shared
3076 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3078 * som.c (som_begin_writing): Account for alignment needs of
3079 subspaces too when writing executables. Never request a negative
3080 bss size. Fixes some problems with demand paged executables,
3081 still having problems with pure executables and shared executables.
3083 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3085 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3086 bfd_zalloc for rawptr, because later on we may call free, not
3089 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3090 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3091 * cisco-core.c: New file.
3092 * Makefile.in: Change accordingly.
3093 * configure.in: Recognize cisco_core_vec.
3094 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3095 * targets.c: Add cisco_core_vec.
3096 * bfd-in2.h: Rebuilt.
3098 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3100 * som.h (som_copyable_section_data_struct): New structure
3101 containing all the private section information which needs
3102 to be copied from input section to output section during
3104 (som_section_data_struct): Remove several fields now in
3105 som_copyable_section_data_struct. Make the space and
3106 subspace dictionaries be pointers (to save space when
3107 only reading objects).
3109 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3110 some references changed. Allocate a copyable data stucture if
3111 none exists. Store info into the copyable data structure.
3112 (bfd_som_set_subsection_attributes): Likewise.
3113 (som_is_space, som_is_subspace, som_is_container): New functions.
3114 Use these instead of directly accessing private data.
3115 (som_prep_headers): Allocate space and subspace headers here.
3116 Fill in some fields in the space/subspace headers from the
3118 (som_bfd_copy_private_section_data): Only copy the stuff
3119 that we really need to make objcopy and strip work. Allocate
3120 the copy_data structure for the output bfd before copying.
3122 * som.h (struct som_exec_data): New structure to hold exec
3123 info that must be preserved when running objcopy/strip.
3124 (struct somdata): Add new "exec_data" field and accessor
3125 macro. Add some comments on how the various fields are used.
3126 (som_section_data_struct): Make is_space and is_subspace bitfields.
3127 Delete unused subspace_index. All references now use the
3128 target_index field within the section structure itself.
3130 * som.c (make_unique_section): Delete unused declaration.
3131 (som_bfd_copy_private_bfd_data): New function.
3132 (som_object_setup): Allocate space for and save exec information
3133 that needs to be copied during objcopy/strip.
3134 (som_mkobject): Do not allocate space for a file header here.
3135 It is not used when only reading SOM objects.
3136 (som_prep_headers): Allocate space for and attach a file header
3137 to the output bfd. For executables, use the saved system_id
3138 value rather than trying to guess the right value. Do not abort
3139 wwhen setting file_hdr->entry* for executables.
3140 (som_begin_writing): For executables, set the exec_entry and
3142 (som_copy_private_backend_section_data): Always return a value.
3144 * libhppa.h (PA_PAGESIZE): Define.
3146 * som.c (SOM_ALIGN): Define.
3147 (som_begin_writing): If writing an executable, initialize all
3148 fields in the exec header to zero. Update fields in the exec
3149 header as sizes of loadable subspaces are computed. Carefully
3150 preserve alignments when building executables. Actually write the
3151 exec after all the fields are filled in.
3153 * Better long-filename handling. Reads SOM ABI compliant extended
3154 names, but doesn't quite write compliant extended names yet.
3155 * som.c (som_slurp_extended_name_table): Delete function. The
3156 generic code will handle things correctly.
3157 (som_slurp_armap): Seek to the beginning of the next member.
3158 (normalize): New function.
3159 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3160 name table into account when computing the file offsets in the
3161 SOM dictionary. Make sure to align to an even boundary.
3162 (som_write_armap): Initialize the checksum to zero.
3163 (ar_maxchars): Fix. Opps.
3165 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3167 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3168 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3170 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3172 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3173 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3174 * bfd-in2.h: Regenerated.
3176 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3177 this was also named trad_unix_bfd_copy_private_bfd_data.
3179 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3181 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3182 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3183 returns NULL, it is not an error. It's possible that some of
3184 these checks are not necessary (because the size can never be
3185 zero), but putting in the checks is the conservative thing to do
3186 in light of the fact that some of these malloc calls replaced
3187 unchecked alloca calls, in which a zero argument would work fine.
3189 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3191 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3192 duplicate definition.
3193 (osf_core_bfd_is_local_label): Define.
3195 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3196 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3197 failure indication, it merely means there are no relocs.
3199 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3200 after NAME, since SunOS /bin/cc can't handle it.
3202 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3204 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3205 From sukes@glue.umd.edu (Tasuki Hirata).
3207 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3209 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3210 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3211 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3213 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3215 * som.c (som_prep_for_fixups): Detect section symbols based
3216 on either the lack of private data or the symbol flags. Do not
3217 munge section symbol names anymore -- they no longer confuse GDB.
3218 (som_begin_writing): Leave space for an exec header if writing
3220 (som_slurp_symbol_table): Recognize both forms of section symbol
3221 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3222 section symbols to be the name of the section they represent.
3223 Debugging symbols begin with "L$0\001", not just "L$".
3225 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3227 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3229 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3230 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3231 and bfd_is_local_label.
3233 * targets.c: Add new entries to the bfd_target structure.
3235 * bfd.c (bfd_copy_private_bfd_data): New definition.
3237 * section.c (bfd_copy_private_section_data): New definition.
3239 * syms.c (bfd_is_local_label): New definition.
3241 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3243 * libbfd.c (bfd_generic_is_local_label): New function.
3245 * *-core.c: Provide default definitions for new functions in
3246 the target vector which all point to bfd_false.
3248 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3249 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3250 Default new vectors for copying private backend data to bfd_true.
3251 Default new vector for determining if a symbol is a local label
3252 to bfd_generic_is_local_label.
3254 * som.c (som_bfd_copy_private_section_data): New function.
3255 (som_bfd_is_local_label): New function.
3256 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3258 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3260 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3262 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3264 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3267 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3268 Indent some of them to GNU standards.
3270 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3271 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3272 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3273 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3274 Update copyright years.
3276 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3278 * som.c (som_prep_for_fixups): A relocation involving the section
3279 symbol for the *ABS* section is really a relocation involving
3281 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3282 undefined symbols. Correctly distinguish between debugger symbols
3283 and section symbols.
3285 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3286 for spaces and subspaces.
3288 * som.c (som_bfd_count_ar_symbols): Fix typo.
3290 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3291 HAS_RELOC based on the object's magic number.
3292 (make_unique_section): Delete function. BFD and its users are
3293 prepared to handle multiple sections with the same name.
3294 (setup_sections): Allocate space on the BFD's obstack to hold
3295 section names. Use bfd_make_setion_anyway rather than the
3296 obsolete make_unique_section.
3297 (som_prep_headers): Choose the correct SOM magic number based
3299 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3301 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3303 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3304 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3305 * Makefile.in, configure.in: Corresponding changes.
3307 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3309 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3311 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3313 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3314 is always located at the start of the data section to allow
3315 recovery of the dynamic info from a stripped executable.
3316 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3319 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3321 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3322 cruft (like the #pragma alloca for AIX).
3323 In addition to that problem, the C alloca calls xmalloc, which
3324 means checking for being out of memory can't work right. The
3325 following changes remove all uses of alloca from BFD.
3326 * hosts/solaris2.h: Remove alloca cruft.
3327 * som.c: Replace alloca with a fixed size auto array.
3328 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3329 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3330 sunos.c: Replace alloca with malloc and appropriate error checking and
3332 * linker.c: Replace alloca with obstack_alloc.
3333 * libbfd.h: Rebuilt.
3335 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3337 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3340 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3342 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3343 Elf*_Off typedefs by their expansion, the typedefs have been
3344 removed from include/elf/internal.h.
3345 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3346 SHT_PROGBITS section.
3348 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3350 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3354 * configure.host: Recognize i[34]86-sequent-*.
3356 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3357 return from bfd_seek indicates an error.
3358 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3359 TRAD_CORE_STACK_OFFSET.
3360 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3361 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3363 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3365 * som.[ch]: Do not include libhppa.h in som.c, instead include
3368 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3369 include it in elf32-hppa.h.
3371 * som.c (log2): Return -1 on error rather than aborting.
3372 (setup_sections): Bubble up an error from log2.
3374 * Changes to make HP C compiler happy in both traditional
3376 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3378 (bfd_som_set_section_attributes): Use unsigned int rather than
3379 unsigned char to avoid GNU-C extensions.
3380 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3381 or failure rather than aborting on failure.
3383 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3385 (bfd_som_attach_aux_hdr): Add prototype.
3386 (hppa_som-gen_reloc_type): Likewise.
3388 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3389 (hppa_look_for_stubs_in_section): Do not return false on failure
3390 until rest of code is ready to handle it. Abort for now.
3392 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3394 * bfd-in2.h: Rebuilt.
3396 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

3402 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
3404 * config.bfd : Add i386-os9k.
3405 * config/i386-os9k.mt : Newly add os9k target makefile.
3407 * i386os9k.c : new file to handle os9k format bfd.
3408 * Makefile.in : Handle new file i386os9k.c
3409 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
3410 * cache.c : Initialize cache_sentinel to 0.

3414 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
3415 action in case where caller specified no argument relocation.
3416 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3417 right in the original relocation and the stub's relocation.
3419 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3420 unused symbols argument.
3422 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3423 than asymbol * for original target symbol. All callers changed.
3424 Set reloc->sym_ptr_ptr appropriately.
3425 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3426 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3427 argument. Use the output symbols when canonicalizing the relocs,
3428 creating them if necessary.
3430 * linker.c (_bfd_generic_link_output_symbols): Do not
3431 rebuild/clobber the output symbols if they already exist.
3433 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3435 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3436 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3437 * bfd-in2.h: Rebuilt.
3439 * srec.c (hex_value): Always set to a size of 256 bytes.
3440 (srec_init): Cosmetic changes.
3442 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3444 * elf32-hppa.c: Second half of major cleanup. More comments,
3445 PARAMize and staticize rest of functions. Delete unused
3446 functions. Delete unused/unnecessary arguments to some functions.
3447 Group static vars together. Abort for bad errors until we have
3448 error code propogation working. Work on spacing and indention.
3449 Add FIXMEs for unresolved problems. Use enums rather than
3450 #defines for lots of things. Merge two functions which build
3451 linker stubs into a single function (so they can easily share a
3452 ton of common code).
3454 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3456 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3457 avoid depending upon right shifts of signed numbers, and to
3458 correct handling of src_mask with lower bits zero.
3460 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3461 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
3462 * elf32-i386.c: Likewise.
3463 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old

3676 bother processing them.

5666 terms of MY, because that causes a recusive invocation of CAT when
5667 expanded within JUMP_TABLE, and ANSI compilers don't expand
5669 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
5670 MY_reloc_howto_type_lookup, and don't define in terms of MY.
5671 (MY_canonicalize_reloc): Don't define in terms of MY.
5672 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
5673 than listing functions.
