3021 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3023 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3025 * som.c (bfd_section_from_som_symbol): Only to do the value
3026 comparison for function symbols within executables.
3028 * som.c (bfd_section_from_som_symbol): Renamed from
3029 som_section_from_subspace_index. Pass in a native SOM symbol.
3030 For executables, iterate through the sections to find out
3031 which contains the symbol's address rather than using the
3032 symbol_info field. (symbol_info has a different meaning for
3033 dynamicly linked executables.)
3035 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3038 * som.c (som_begin_writing): Fix braino (one call to align
3039 space/subspace data was done unconditionally rather than
3040 just for executables.)
3042 * som.c (som_begin_writing): Align text in all executables to
3043 make HPUX kernel happy. Fixes strip/objcopy for shared
3046 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3048 * som.c (som_begin_writing): Account for alignment needs of
3049 subspaces too when writing executables. Never request a negative
3050 bss size. Fixes some problems with demand paged executables,
3051 still having problems with pure executables and shared executables.
3053 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3055 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3056 bfd_zalloc for rawptr, because later on we may call free, not
3059 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3060 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3061 * cisco-core.c: New file.
3062 * Makefile.in: Change accordingly.
3063 * configure.in: Recognize cisco_core_vec.
3064 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3065 * targets.c: Add cisco_core_vec.
3066 * bfd-in2.h: Rebuilt.
3068 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3070 * som.h (som_copyable_section_data_struct): New structure
3071 containing all the private section information which needs
3072 to be copied from input section to output section during
3074 (som_section_data_struct): Remove several fields now in
3075 som_copyable_section_data_struct. Make the space and
3076 subspace dictionaries be pointers (to save space when
3077 only reading objects).
3079 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3080 some references changed. Allocate a copyable data stucture if
3081 none exists. Store info into the copyable data structure.
3082 (bfd_som_set_subsection_attributes): Likewise.
3083 (som_is_space, som_is_subspace, som_is_container): New functions.
3084 Use these instead of directly accessing private data.
3085 (som_prep_headers): Allocate space and subspace headers here.
3086 Fill in some fields in the space/subspace headers from the
3088 (som_bfd_copy_private_section_data): Only copy the stuff
3089 that we really need to make objcopy and strip work. Allocate
3090 the copy_data structure for the output bfd before copying.
3092 * som.h (struct som_exec_data): New structure to hold exec
3093 info that must be preserved when running objcopy/strip.
3094 (struct somdata): Add new "exec_data" field and accessor
3095 macro. Add some comments on how the various fields are used.
3096 (som_section_data_struct): Make is_space and is_subspace bitfields.
3097 Delete unused subspace_index. All references now use the
3098 target_index field within the section structure itself.
3100 * som.c (make_unique_section): Delete unused declaration.
3101 (som_bfd_copy_private_bfd_data): New function.
3102 (som_object_setup): Allocate space for and save exec information
3103 that needs to be copied during objcopy/strip.
3104 (som_mkobject): Do not allocate space for a file header here.
3105 It is not used when only reading SOM objects.
3106 (som_prep_headers): Allocate space for and attach a file header
3107 to the output bfd. For executables, use the saved system_id
3108 value rather than trying to guess the right value. Do not abort
3109 wwhen setting file_hdr->entry* for executables.
3110 (som_begin_writing): For executables, set the exec_entry and
3112 (som_copy_private_backend_section_data): Always return a value.
3114 * libhppa.h (PA_PAGESIZE): Define.
3116 * som.c (SOM_ALIGN): Define.
3117 (som_begin_writing): If writing an executable, initialize all
3118 fields in the exec header to zero. Update fields in the exec
3119 header as sizes of loadable subspaces are computed. Carefully
3120 preserve alignments when building executables. Actually write the
3121 exec after all the fields are filled in.
3123 * Better long-filename handling. Reads SOM ABI compliant extended
3124 names, but doesn't quite write compliant extended names yet.
3125 * som.c (som_slurp_extended_name_table): Delete function. The
3126 generic code will handle things correctly.
3127 (som_slurp_armap): Seek to the beginning of the next member.
3128 (normalize): New function.
3129 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3130 name table into account when computing the file offsets in the
3131 SOM dictionary. Make sure to align to an even boundary.
3132 (som_write_armap): Initialize the checksum to zero.
3133 (ar_maxchars): Fix. Opps.
3135 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3137 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3138 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3140 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3142 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3143 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3144 * bfd-in2.h: Regenerated.
3146 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3147 this was also named trad_unix_bfd_copy_private_bfd_data.
3149 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3151 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3152 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3153 returns NULL, it is not an error. It's possible that some of
3154 these checks are not necessary (because the size can never be
3155 zero), but putting in the checks is the conservative thing to do
3156 in light of the fact that some of these malloc calls replaced
3157 unchecked alloca calls, in which a zero argument would work fine.
3159 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3161 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3162 duplicate definition.
3163 (osf_core_bfd_is_local_label): Define.
3165 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3166 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3167 failure indication, it merely means there are no relocs.
3169 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3170 after NAME, since SunOS /bin/cc can't handle it.
3172 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3174 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3175 From sukes@glue.umd.edu (Tasuki Hirata).
3177 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3179 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3180 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3181 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3183 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3185 * som.c (som_prep_for_fixups): Detect section symbols based
3186 on either the lack of private data or the symbol flags. Do not
3187 munge section symbol names anymore -- they no longer confuse GDB.
3188 (som_begin_writing): Leave space for an exec header if writing
3190 (som_slurp_symbol_table): Recognize both forms of section symbol
3191 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3192 section symbols to be the name of the section they represent.
3193 Debugging symbols begin with "L$0\001", not just "L$".
3195 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3197 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3199 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3200 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3201 and bfd_is_local_label.
3203 * targets.c: Add new entries to the bfd_target structure.
3205 * bfd.c (bfd_copy_private_bfd_data): New definition.
3207 * section.c (bfd_copy_private_section_data): New definition.
3209 * syms.c (bfd_is_local_label): New definition.
3211 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3213 * libbfd.c (bfd_generic_is_local_label): New function.
3215 * *-core.c: Provide default definitions for new functions in
3216 the target vector which all point to bfd_false.
3218 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3219 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3220 Default new vectors for copying private backend data to bfd_true.
3221 Default new vector for determining if a symbol is a local label
3222 to bfd_generic_is_local_label.
3224 * som.c (som_bfd_copy_private_section_data): New function.
3225 (som_bfd_is_local_label): New function.
3226 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3228 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3230 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3232 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3234 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3237 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3238 Indent some of them to GNU standards.
3240 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3241 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3242 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3243 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3244 Update copyright years.
3246 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3248 * som.c (som_prep_for_fixups): A relocation involving the section
3249 symbol for the *ABS* section is really a relocation involving
3251 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3252 undefined symbols. Correctly distinguish between debugger symbols
3253 and section symbols.
3255 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3256 for spaces and subspaces.
3258 * som.c (som_bfd_count_ar_symbols): Fix typo.
3260 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3261 HAS_RELOC based on the object's magic number.
3262 (make_unique_section): Delete function. BFD and its users are
3263 prepared to handle multiple sections with the same name.
3264 (setup_sections): Allocate space on the BFD's obstack to hold
3265 section names. Use bfd_make_setion_anyway rather than the
3266 obsolete make_unique_section.
3267 (som_prep_headers): Choose the correct SOM magic number based
3269 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3271 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3273 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3274 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3275 * Makefile.in, configure.in: Corresponding changes.
3277 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3279 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3281 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3283 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3284 is always located at the start of the data section to allow
3285 recovery of the dynamic info from a stripped executable.
3286 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3289 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3291 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3292 cruft (like the #pragma alloca for AIX).
3293 In addition to that problem, the C alloca calls xmalloc, which
3294 means checking for being out of memory can't work right. The
3295 following changes remove all uses of alloca from BFD.
3296 * hosts/solaris2.h: Remove alloca cruft.
3297 * som.c: Replace alloca with a fixed size auto array.
3298 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3299 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3300 sunos.c: Replace alloca with malloc and appropriate error checking and
3302 * linker.c: Replace alloca with obstack_alloc.
3303 * libbfd.h: Rebuilt.
3305 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3307 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3310 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3312 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3313 Elf*_Off typedefs by their expansion, the typedefs have been
3314 removed from include/elf/internal.h.
3315 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3316 SHT_PROGBITS section.
3318 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3320 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3324 * configure.host: Recognize i[34]86-sequent-*.
3326 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3327 return from bfd_seek indicates an error.
3328 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3329 TRAD_CORE_STACK_OFFSET.
3330 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3331 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3333 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3335 * som.[ch]: Do not include libhppa.h in som.c, instead include
3338 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3339 include it in elf32-hppa.h.
3341 * som.c (log2): Return -1 on error rather than aborting.
3342 (setup_sections): Bubble up an error from log2.
3344 * Changes to make HP C compiler happy in both traditional
3346 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3348 (bfd_som_set_section_attributes): Use unsigned int rather than
3349 unsigned char to avoid GNU-C extensions.
3350 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3351 or failure rather than aborting on failure.
3353 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3355 (bfd_som_attach_aux_hdr): Add prototype.
3356 (hppa_som-gen_reloc_type): Likewise.
3358 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3359 (hppa_look_for_stubs_in_section): Do not return false on failure
3360 until rest of code is ready to handle it. Abort for now.
3362 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3364 * bfd-in2.h: Rebuilt.
3366 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
3368 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

3372 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
3374 * config.bfd : Add i386-os9k.
3375 * config/i386-os9k.mt : Newly add os9k target makefile.
3377 * i386os9k.c : new file to handle os9k format bfd.
3378 * Makefile.in : Handle new file i386os9k.c
3379 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
3380 * cache.c : Initialize cache_sentinel to 0.

3384 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
3385 action in case where caller specified no argument relocation.
3386 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3387 right in the original relocation and the stub's relocation.
3389 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3390 unused symbols argument.
3392 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3393 than asymbol * for original target symbol. All callers changed.
3394 Set reloc->sym_ptr_ptr appropriately.
3395 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3396 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3397 argument. Use the output symbols when canonicalizing the relocs,
3398 creating them if necessary.
3400 * linker.c (_bfd_generic_link_output_symbols): Do not
3401 rebuild/clobber the output symbols if they already exist.
3403 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3405 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3406 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3407 * bfd-in2.h: Rebuilt.
3409 * srec.c (hex_value): Always set to a size of 256 bytes.
3410 (srec_init): Cosmetic changes.
3412 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3414 * elf32-hppa.c: Second half of major cleanup. More comments,
3415 PARAMize and staticize rest of functions. Delete unused
3416 functions. Delete unused/unnecessary arguments to some functions.
3417 Group static vars together. Abort for bad errors until we have
3418 error code propogation working. Work on spacing and indention.
3419 Add FIXMEs for unresolved problems. Use enums rather than
3420 #defines for lots of things. Merge two functions which build
3421 linker stubs into a single function (so they can easily share a
3422 ton of common code).
3424 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3426 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3427 avoid depending upon right shifts of signed numbers, and to
3428 correct handling of src_mask with lower bits zero.
3430 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3431 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3438 (write_shdrs_and_ehdr): Make count unsigned.
3439 (assign_file_positions_for_relocs): Make i unsigned.
3440 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
3441 (section_from_elf_index): Make index argument unsigned.
3443 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
3445 * elfcode.h: Don't include assert.h.
3446 (swap_out_syms): Use BFD_ASSERT rather than assert.

3451 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
3454 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3456 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3458 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3459 (elf_hppa_tc_make_sections): Likewise.
3460 (elf_hppa_final_processing): Add extern decl.
3462 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3463 comments. PARAMize some static functions. Delete unused functions.
3464 Delete unused/unnecessary arguments to many functions. Group
3465 static vars together. Collapse common case statements together
3466 in many places. Use default case when possible instead of listing
3467 each case separately. Abort for bad errors until we get error
3468 code propogation working. Work on spacing and indention problems.
3469 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3470 COMPLEX relocation support (it's never used anyway).
3471 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3472 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3473 (elf_hppa_tc_make_sections): Likewise.
3475 * format.c (bfd_check_format_matches): Initialize matching_vector

4319 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
4320 use get_value to get the symbol value and check for undefined
4322 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4323 undefined, look it up in the linker hash table.
4325 * aoutx.h (translate_symbol_table): The string index 0 has a

4350 The sparc (and possibly other?) NLM format requires a different
4351 way to write exports, so add a write_export field to the backend
4352 data (and set it to NULL for everything but the sparc).
