3018 dynamicly linked executables.)
3020 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3023 * som.c (som_begin_writing): Fix braino (one call to align
3024 space/subspace data was done unconditionally rather than
3025 just for executables.)
3027 * som.c (som_begin_writing): Align text in all executables to
3028 make HPUX kernel happy. Fixes strip/objcopy for shared
3031 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3033 * som.c (som_begin_writing): Account for alignment needs of
3034 subspaces too when writing executables. Never request a negative
3035 bss size. Fixes some problems with demand paged executables,
3036 still having problems with pure executables and shared executables.
3038 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3040 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3041 bfd_zalloc for rawptr, because later on we may call free, not
3044 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3045 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3046 * cisco-core.c: New file.
3047 * Makefile.in: Change accordingly.
3048 * configure.in: Recognize cisco_core_vec.
3049 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3050 * targets.c: Add cisco_core_vec.
3051 * bfd-in2.h: Rebuilt.
3053 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3055 * som.h (som_copyable_section_data_struct): New structure
3056 containing all the private section information which needs
3057 to be copied from input section to output section during
3059 (som_section_data_struct): Remove several fields now in
3060 som_copyable_section_data_struct. Make the space and
3061 subspace dictionaries be pointers (to save space when
3062 only reading objects).
3064 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3065 some references changed. Allocate a copyable data stucture if
3066 none exists. Store info into the copyable data structure.
3067 (bfd_som_set_subsection_attributes): Likewise.
3068 (som_is_space, som_is_subspace, som_is_container): New functions.
3069 Use these instead of directly accessing private data.
3070 (som_prep_headers): Allocate space and subspace headers here.
3071 Fill in some fields in the space/subspace headers from the
3073 (som_bfd_copy_private_section_data): Only copy the stuff
3074 that we really need to make objcopy and strip work. Allocate
3075 the copy_data structure for the output bfd before copying.
3077 * som.h (struct som_exec_data): New structure to hold exec
3078 info that must be preserved when running objcopy/strip.
3079 (struct somdata): Add new "exec_data" field and accessor
3080 macro. Add some comments on how the various fields are used.
3081 (som_section_data_struct): Make is_space and is_subspace bitfields.
3082 Delete unused subspace_index. All references now use the
3083 target_index field within the section structure itself.
3085 * som.c (make_unique_section): Delete unused declaration.
3086 (som_bfd_copy_private_bfd_data): New function.
3087 (som_object_setup): Allocate space for and save exec information
3088 that needs to be copied during objcopy/strip.
3089 (som_mkobject): Do not allocate space for a file header here.
3090 It is not used when only reading SOM objects.
3091 (som_prep_headers): Allocate space for and attach a file header
3092 to the output bfd. For executables, use the saved system_id
3093 value rather than trying to guess the right value. Do not abort
3094 wwhen setting file_hdr->entry* for executables.
3095 (som_begin_writing): For executables, set the exec_entry and
3097 (som_copy_private_backend_section_data): Always return a value.
3099 * libhppa.h (PA_PAGESIZE): Define.
3101 * som.c (SOM_ALIGN): Define.
3102 (som_begin_writing): If writing an executable, initialize all
3103 fields in the exec header to zero. Update fields in the exec
3104 header as sizes of loadable subspaces are computed. Carefully
3105 preserve alignments when building executables. Actually write the
3106 exec after all the fields are filled in.
3108 * Better long-filename handling. Reads SOM ABI compliant extended
3109 names, but doesn't quite write compliant extended names yet.
3110 * som.c (som_slurp_extended_name_table): Delete function. The
3111 generic code will handle things correctly.
3112 (som_slurp_armap): Seek to the beginning of the next member.
3113 (normalize): New function.
3114 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3115 name table into account when computing the file offsets in the
3116 SOM dictionary. Make sure to align to an even boundary.
3117 (som_write_armap): Initialize the checksum to zero.
3118 (ar_maxchars): Fix. Opps.
3120 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3122 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3123 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3125 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3127 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3128 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3129 * bfd-in2.h: Regenerated.
3131 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3132 this was also named trad_unix_bfd_copy_private_bfd_data.
3134 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3136 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3137 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3138 returns NULL, it is not an error. It's possible that some of
3139 these checks are not necessary (because the size can never be
3140 zero), but putting in the checks is the conservative thing to do
3141 in light of the fact that some of these malloc calls replaced
3142 unchecked alloca calls, in which a zero argument would work fine.
3144 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3146 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3147 duplicate definition.
3148 (osf_core_bfd_is_local_label): Define.
3150 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3151 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3152 failure indication, it merely means there are no relocs.
3154 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3155 after NAME, since SunOS /bin/cc can't handle it.
3157 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3159 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3160 From sukes@glue.umd.edu (Tasuki Hirata).
3162 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3164 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3165 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3166 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3168 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3170 * som.c (som_prep_for_fixups): Detect section symbols based
3171 on either the lack of private data or the symbol flags. Do not
3172 munge section symbol names anymore -- they no longer confuse GDB.
3173 (som_begin_writing): Leave space for an exec header if writing
3175 (som_slurp_symbol_table): Recognize both forms of section symbol
3176 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3177 section symbols to be the name of the section they represent.
3178 Debugging symbols begin with "L$0\001", not just "L$".
3180 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3182 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3184 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3185 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3186 and bfd_is_local_label.
3188 * targets.c: Add new entries to the bfd_target structure.
3190 * bfd.c (bfd_copy_private_bfd_data): New definition.
3192 * section.c (bfd_copy_private_section_data): New definition.
3194 * syms.c (bfd_is_local_label): New definition.
3196 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3198 * libbfd.c (bfd_generic_is_local_label): New function.
3200 * *-core.c: Provide default definitions for new functions in
3201 the target vector which all point to bfd_false.
3203 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3204 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3205 Default new vectors for copying private backend data to bfd_true.
3206 Default new vector for determining if a symbol is a local label
3207 to bfd_generic_is_local_label.
3209 * som.c (som_bfd_copy_private_section_data): New function.
3210 (som_bfd_is_local_label): New function.
3211 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3213 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3215 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3217 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3219 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3222 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3223 Indent some of them to GNU standards.
3225 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3226 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3227 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3228 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3229 Update copyright years.
3231 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3233 * som.c (som_prep_for_fixups): A relocation involving the section
3234 symbol for the *ABS* section is really a relocation involving
3236 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3237 undefined symbols. Correctly distinguish between debugger symbols
3238 and section symbols.
3240 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3241 for spaces and subspaces.
3243 * som.c (som_bfd_count_ar_symbols): Fix typo.
3245 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3246 HAS_RELOC based on the object's magic number.
3247 (make_unique_section): Delete function. BFD and its users are
3248 prepared to handle multiple sections with the same name.
3249 (setup_sections): Allocate space on the BFD's obstack to hold
3250 section names. Use bfd_make_setion_anyway rather than the
3251 obsolete make_unique_section.
3252 (som_prep_headers): Choose the correct SOM magic number based
3254 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3256 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3258 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3259 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3260 * Makefile.in, configure.in: Corresponding changes.
3262 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3264 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.

3268 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3269 is always located at the start of the data section to allow
3270 recovery of the dynamic info from a stripped executable.
3271 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3274 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3276 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3277 cruft (like the #pragma alloca for AIX).
3278 In addition to that problem, the C alloca calls xmalloc, which
3279 means checking for being out of memory can't work right. The
3280 following changes remove all uses of alloca from BFD.
3281 * hosts/solaris2.h: Remove alloca cruft.
3282 * som.c: Replace alloca with a fixed size auto array.
3283 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3284 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3285 sunos.c: Replace alloca with malloc and appropriate error checking and
3287 * linker.c: Replace alloca with obstack_alloc.
3288 * libbfd.h: Rebuilt.
3290 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3292 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3295 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3297 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3298 Elf*_Off typedefs by their expansion, the typedefs have been
3299 removed from include/elf/internal.h.
3300 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3301 SHT_PROGBITS section.
3303 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3305 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3311 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3312 return from bfd_seek indicates an error.
3313 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3314 TRAD_CORE_STACK_OFFSET.
3315 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3316 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3318 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3320 * som.[ch]: Do not include libhppa.h in som.c, instead include
3323 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3324 include it in elf32-hppa.h.
3326 * som.c (log2): Return -1 on error rather than aborting.
3327 (setup_sections): Bubble up an error from log2.
3329 * Changes to make HP C compiler happy in both traditional
3331 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3333 (bfd_som_set_section_attributes): Use unsigned int rather than
3334 unsigned char to avoid GNU-C extensions.
3335 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3336 or failure rather than aborting on failure.
3338 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3340 (bfd_som_attach_aux_hdr): Add prototype.
3341 (hppa_som-gen_reloc_type): Likewise.
3343 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3344 (hppa_look_for_stubs_in_section): Do not return false on failure
3345 until rest of code is ready to handle it. Abort for now.

3349 * bfd-in2.h: Rebuilt.
3351 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

3370 action in case where caller specified no argument relocation.
3371 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3372 right in the original relocation and the stub's relocation.
3374 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3375 unused symbols argument.
3377 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3378 than asymbol * for original target symbol. All callers changed.
3379 Set reloc->sym_ptr_ptr appropriately.
3380 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3381 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3382 argument. Use the output symbols when canonicalizing the relocs,
3383 creating them if necessary.
3385 * linker.c (_bfd_generic_link_output_symbols): Do not
3386 rebuild/clobber the output symbols if they already exist.
3388 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3390 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3391 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3392 * bfd-in2.h: Rebuilt.
3394 * srec.c (hex_value): Always set to a size of 256 bytes.
3395 (srec_init): Cosmetic changes.
3397 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3399 * elf32-hppa.c: Second half of major cleanup. More comments,
3400 PARAMize and staticize rest of functions. Delete unused
3401 functions. Delete unused/unnecessary arguments to some functions.
3402 Group static vars together. Abort for bad errors until we have
3403 error code propogation working. Work on spacing and indention.
3404 Add FIXMEs for unresolved problems. Use enums rather than
3405 #defines for lots of things. Merge two functions which build
3406 linker stubs into a single function (so they can easily share a
3407 ton of common code).
3409 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3411 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3412 avoid depending upon right shifts of signed numbers, and to
3413 correct handling of src_mask with lower bits zero.
3415 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3416 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3426 (section_from_elf_index): Make index argument unsigned.
3428 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
3430 * elfcode.h: Don't include assert.h.

3441 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3443 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3444 (elf_hppa_tc_make_sections): Likewise.
3445 (elf_hppa_final_processing): Add extern decl.
3447 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3448 comments. PARAMize some static functions. Delete unused functions.
3449 Delete unused/unnecessary arguments to many functions. Group
3450 static vars together. Collapse common case statements together
3451 in many places. Use default case when possible instead of listing
3452 each case separately. Abort for bad errors until we get error
3453 code propogation working. Work on spacing and indention problems.
3454 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3455 COMPLEX relocation support (it's never used anyway).
3456 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3457 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3458 (elf_hppa_tc_make_sections): Likewise.
3460 * format.c (bfd_check_format_matches): Initialize matching_vector
3461 to keep gcc -Wall quiet.
3463 * elfcode.h (elf_slurp_reloca_table): Fix typo.

3466 not "sizeof (som_symbol_type *)".
3468 * elfcode.h (elf_get_symtab_upper_bound): Use "sizeof (asymbol *)"
3469 not "sizeof (asymbol"). Opps.
3471 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3473 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4197 bfd_som_set_subsection_attributes): Change parameters from char
4198 to int. Following a prototype with an old-style function definition

4301 the symbol value and check for undefined symbols.
4302 (get_value): If the symbol is undefined, look it up in the linker
4304 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
4305 use get_value to get the symbol value and check for undefined
4307 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4308 undefined, look it up in the linker hash table.
4310 * aoutx.h (translate_symbol_table): The string index 0 has a

4335 The sparc (and possibly other?) NLM format requires a different
4336 way to write exports, so add a write_export field to the backend
4337 data (and set it to NULL for everything but the sparc).
