3020 dynamicly linked executables.)
3022 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3025 * som.c (som_begin_writing): Fix braino (one call to align
3026 space/subspace data was done unconditionally rather than
3027 just for executables.)
3029 * som.c (som_begin_writing): Align text in all executables to
3030 make HPUX kernel happy. Fixes strip/objcopy for shared
3033 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3035 * som.c (som_begin_writing): Account for alignment needs of
3036 subspaces too when writing executables. Never request a negative
3037 bss size. Fixes some problems with demand paged executables,
3038 still having problems with pure executables and shared executables.
3040 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3042 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3043 bfd_zalloc for rawptr, because later on we may call free, not
3046 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3047 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3048 * cisco-core.c: New file.
3049 * Makefile.in: Change accordingly.
3050 * configure.in: Recognize cisco_core_vec.
3051 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3052 * targets.c: Add cisco_core_vec.
3053 * bfd-in2.h: Rebuilt.
3055 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3057 * som.h (som_copyable_section_data_struct): New structure
3058 containing all the private section information which needs
3059 to be copied from input section to output section during
3061 (som_section_data_struct): Remove several fields now in
3062 som_copyable_section_data_struct. Make the space and
3063 subspace dictionaries be pointers (to save space when
3064 only reading objects).
3066 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3067 some references changed. Allocate a copyable data stucture if
3068 none exists. Store info into the copyable data structure.
3069 (bfd_som_set_subsection_attributes): Likewise.
3070 (som_is_space, som_is_subspace, som_is_container): New functions.
3071 Use these instead of directly accessing private data.
3072 (som_prep_headers): Allocate space and subspace headers here.
3073 Fill in some fields in the space/subspace headers from the
3075 (som_bfd_copy_private_section_data): Only copy the stuff
3076 that we really need to make objcopy and strip work. Allocate
3077 the copy_data structure for the output bfd before copying.
3079 * som.h (struct som_exec_data): New structure to hold exec
3080 info that must be preserved when running objcopy/strip.
3081 (struct somdata): Add new "exec_data" field and accessor
3082 macro. Add some comments on how the various fields are used.
3083 (som_section_data_struct): Make is_space and is_subspace bitfields.
3084 Delete unused subspace_index. All references now use the
3085 target_index field within the section structure itself.
3087 * som.c (make_unique_section): Delete unused declaration.
3088 (som_bfd_copy_private_bfd_data): New function.
3089 (som_object_setup): Allocate space for and save exec information
3090 that needs to be copied during objcopy/strip.
3091 (som_mkobject): Do not allocate space for a file header here.
3092 It is not used when only reading SOM objects.
3093 (som_prep_headers): Allocate space for and attach a file header
3094 to the output bfd. For executables, use the saved system_id
3095 value rather than trying to guess the right value. Do not abort
3096 wwhen setting file_hdr->entry* for executables.
3097 (som_begin_writing): For executables, set the exec_entry and
3099 (som_copy_private_backend_section_data): Always return a value.
3101 * libhppa.h (PA_PAGESIZE): Define.
3103 * som.c (SOM_ALIGN): Define.
3104 (som_begin_writing): If writing an executable, initialize all
3105 fields in the exec header to zero. Update fields in the exec
3106 header as sizes of loadable subspaces are computed. Carefully
3107 preserve alignments when building executables. Actually write the
3108 exec after all the fields are filled in.
3110 * Better long-filename handling. Reads SOM ABI compliant extended
3111 names, but doesn't quite write compliant extended names yet.
3112 * som.c (som_slurp_extended_name_table): Delete function. The
3113 generic code will handle things correctly.
3114 (som_slurp_armap): Seek to the beginning of the next member.
3115 (normalize): New function.
3116 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3117 name table into account when computing the file offsets in the
3118 SOM dictionary. Make sure to align to an even boundary.
3119 (som_write_armap): Initialize the checksum to zero.
3120 (ar_maxchars): Fix. Opps.
3122 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3124 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3125 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3127 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3129 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3130 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3131 * bfd-in2.h: Regenerated.
3133 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3134 this was also named trad_unix_bfd_copy_private_bfd_data.
3136 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3138 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3139 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3140 returns NULL, it is not an error. It's possible that some of
3141 these checks are not necessary (because the size can never be
3142 zero), but putting in the checks is the conservative thing to do
3143 in light of the fact that some of these malloc calls replaced
3144 unchecked alloca calls, in which a zero argument would work fine.
3146 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3148 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3149 duplicate definition.
3150 (osf_core_bfd_is_local_label): Define.
3152 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3153 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3154 failure indication, it merely means there are no relocs.
3156 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3157 after NAME, since SunOS /bin/cc can't handle it.
3159 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3161 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3162 From sukes@glue.umd.edu (Tasuki Hirata).
3164 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3166 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3167 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3168 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3170 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3172 * som.c (som_prep_for_fixups): Detect section symbols based
3173 on either the lack of private data or the symbol flags. Do not
3174 munge section symbol names anymore -- they no longer confuse GDB.
3175 (som_begin_writing): Leave space for an exec header if writing
3177 (som_slurp_symbol_table): Recognize both forms of section symbol
3178 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3179 section symbols to be the name of the section they represent.
3180 Debugging symbols begin with "L$0\001", not just "L$".
3182 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3184 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3186 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3187 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3188 and bfd_is_local_label.
3190 * targets.c: Add new entries to the bfd_target structure.
3192 * bfd.c (bfd_copy_private_bfd_data): New definition.
3194 * section.c (bfd_copy_private_section_data): New definition.
3196 * syms.c (bfd_is_local_label): New definition.
3198 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3200 * libbfd.c (bfd_generic_is_local_label): New function.
3202 * *-core.c: Provide default definitions for new functions in
3203 the target vector which all point to bfd_false.
3205 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3206 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3207 Default new vectors for copying private backend data to bfd_true.
3208 Default new vector for determining if a symbol is a local label
3209 to bfd_generic_is_local_label.
3211 * som.c (som_bfd_copy_private_section_data): New function.
3212 (som_bfd_is_local_label): New function.
3213 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3215 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3217 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3219 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3221 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3224 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3225 Indent some of them to GNU standards.
3227 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3228 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3229 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3230 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3231 Update copyright years.
3233 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3235 * som.c (som_prep_for_fixups): A relocation involving the section
3236 symbol for the *ABS* section is really a relocation involving
3238 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3239 undefined symbols. Correctly distinguish between debugger symbols
3240 and section symbols.
3242 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3243 for spaces and subspaces.
3245 * som.c (som_bfd_count_ar_symbols): Fix typo.
3247 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3248 HAS_RELOC based on the object's magic number.
3249 (make_unique_section): Delete function. BFD and its users are
3250 prepared to handle multiple sections with the same name.
3251 (setup_sections): Allocate space on the BFD's obstack to hold
3252 section names. Use bfd_make_setion_anyway rather than the
3253 obsolete make_unique_section.
3254 (som_prep_headers): Choose the correct SOM magic number based
3256 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3258 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3260 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3261 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3262 * Makefile.in, configure.in: Corresponding changes.
3264 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3266 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.

3270 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3271 is always located at the start of the data section to allow
3272 recovery of the dynamic info from a stripped executable.
3273 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3276 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3278 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3279 cruft (like the #pragma alloca for AIX).
3280 In addition to that problem, the C alloca calls xmalloc, which
3281 means checking for being out of memory can't work right. The
3282 following changes remove all uses of alloca from BFD.
3283 * hosts/solaris2.h: Remove alloca cruft.
3284 * som.c: Replace alloca with a fixed size auto array.
3285 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3286 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3287 sunos.c: Replace alloca with malloc and appropriate error checking and
3289 * linker.c: Replace alloca with obstack_alloc.
3290 * libbfd.h: Rebuilt.
3292 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3294 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3297 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3299 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3300 Elf*_Off typedefs by their expansion, the typedefs have been
3301 removed from include/elf/internal.h.
3302 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3303 SHT_PROGBITS section.
3305 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3307 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3313 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3314 return from bfd_seek indicates an error.
3315 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3316 TRAD_CORE_STACK_OFFSET.
3317 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3318 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3320 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3322 * som.[ch]: Do not include libhppa.h in som.c, instead include
3325 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3326 include it in elf32-hppa.h.
3328 * som.c (log2): Return -1 on error rather than aborting.
3329 (setup_sections): Bubble up an error from log2.
3331 * Changes to make HP C compiler happy in both traditional
3333 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3335 (bfd_som_set_section_attributes): Use unsigned int rather than
3336 unsigned char to avoid GNU-C extensions.
3337 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3338 or failure rather than aborting on failure.
3340 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3342 (bfd_som_attach_aux_hdr): Add prototype.
3343 (hppa_som-gen_reloc_type): Likewise.
3345 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3346 (hppa_look_for_stubs_in_section): Do not return false on failure
3347 until rest of code is ready to handle it. Abort for now.

3372 action in case where caller specified no argument relocation.
3373 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3374 right in the original relocation and the stub's relocation.
3376 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3377 unused symbols argument.
3379 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3380 than asymbol * for original target symbol. All callers changed.
3381 Set reloc->sym_ptr_ptr appropriately.
3382 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3383 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3384 argument. Use the output symbols when canonicalizing the relocs,
3385 creating them if necessary.
3387 * linker.c (_bfd_generic_link_output_symbols): Do not
3388 rebuild/clobber the output symbols if they already exist.
3390 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3392 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3393 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3394 * bfd-in2.h: Rebuilt.
3396 * srec.c (hex_value): Always set to a size of 256 bytes.
3397 (srec_init): Cosmetic changes.
3399 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3401 * elf32-hppa.c: Second half of major cleanup. More comments,
3402 PARAMize and staticize rest of functions. Delete unused
3403 functions. Delete unused/unnecessary arguments to some functions.
3404 Group static vars together. Abort for bad errors until we have
3405 error code propogation working. Work on spacing and indention.
3406 Add FIXMEs for unresolved problems. Use enums rather than
3407 #defines for lots of things. Merge two functions which build
3408 linker stubs into a single function (so they can easily share a
3409 ton of common code).
3411 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3413 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3414 avoid depending upon right shifts of signed numbers, and to
3415 correct handling of src_mask with lower bits zero.
3417 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3418 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3428 (section_from_elf_index): Make index argument unsigned.
3430 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
3432 * elfcode.h: Don't include assert.h.

3443 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3445 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3446 (elf_hppa_tc_make_sections): Likewise.
3447 (elf_hppa_final_processing): Add extern decl.
3449 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3450 comments. PARAMize some static functions. Delete unused functions.
3451 Delete unused/unnecessary arguments to many functions. Group
3452 static vars together. Collapse common case statements together
3453 in many places. Use default case when possible instead of listing
3454 each case separately. Abort for bad errors until we get error
3455 code propogation working. Work on spacing and indention problems.
3456 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3457 COMPLEX relocation support (it's never used anyway).
3458 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3459 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3460 (elf_hppa_tc_make_sections): Likewise.
3462 * format.c (bfd_check_format_matches): Initialize matching_vector
3463 to keep gcc -Wall quiet.
3465 * elfcode.h (elf_slurp_reloca_table): Fix typo.

3468 not "sizeof (som_symbol_type *)".
3470 * elfcode.h (elf_get_symtab_upper_bound): Use "sizeof (asymbol *)"
3471 not "sizeof (asymbol"). Opps.
3473 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3475 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4304 (get_value): If the symbol is undefined, look it up in the linker
4306 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
4307 use get_value to get the symbol value and check for undefined
4309 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4310 undefined, look it up in the linker hash table.
4312 * aoutx.h (translate_symbol_table): The string index 0 has a

4337 The sparc (and possibly other?) NLM format requires a different
4338 way to write exports, so add a write_export field to the backend
4339 data (and set it to NULL for everything but the sparc).
