3154 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3155 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3156 instead of bitsize to add_to_set call back.
3157 (_bfd_generic_final_link): Account for link_order relocs when
3158 allocating space for relocations. Handle them in link_order loop.
3159 (_bfd_generic_reloc_link_order): New function.
3160 (_bfd_default_link_order): If a reloc_link_order is seen here,
3161 abort.
3162 (_bfd_count_link_order_relocs): New function.
3163 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3164 argument from declaration.
3165 (_bfd_generic_reloc_link_order): Declare.
3166 (_bfd_count_link_order_relocs): Declare.
3167 * libbfd.h: Rebuilt.
3168 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3169 call to _bfd_generic_link_add_one_symbol.
3170 (NAME(aout,final_link)): Account for link_order relocs when
3171 allocating space for relocations. Handle them after handling all
3172 input BFDs.
3173 (aout_link_reloc_link_order): New function.
3174 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
3175 call to _bfd_generic_link_add_one_symbol.
3176 (ecoff_bfd_final_link): Account for link_order relocs when
3177 allocating space for relocations. Handle them in link_order loop.
3178 (ecoff_link_write_external): Set the storage class of a defined
3179 linker created symbol based on the section it is in. Correct
3180 bfd_link_hash_weak case to use .sc rather than .st.
3181 (ecoff_reloc_link_order): New function.
3182 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3183 BFD_RELOC_CTOR.
3184 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
3185
3186 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
3187 and buf.
3188
3189 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3190 bfd_zmalloc. Free a pointer, not a union.
3191 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3192
3193 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3194
3195 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3196
3197 * som.c (bfd_section_from_som_symbol): Only to do the value
3198 comparison for function symbols within executables.
3199
3200 * som.c (bfd_section_from_som_symbol): Renamed from
3201 som_section_from_subspace_index. Pass in a native SOM symbol.
3202 For executables, iterate through the sections to find out
3203 which contains the symbol's address rather than using the
3204 symbol_info field. (symbol_info has a different meaning for
3205 dynamicly linked executables.)
3206
3207 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3208 bfd_zmalloc.
3209
3210 * som.c (som_begin_writing): Fix braino (one call to align
3211 space/subspace data was done unconditionally rather than
3212 just for executables.)
3213
3214 * som.c (som_begin_writing): Align text in all executables to
3215 make HPUX kernel happy. Fixes strip/objcopy for shared
3216 executables.
3217
3218 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3219
3220 * som.c (som_begin_writing): Account for alignment needs of
3221 subspaces too when writing executables. Never request a negative
3222 bss size. Fixes some problems with demand paged executables,
3223 still having problems with pure executables and shared executables.
3224
3225 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3226
3227 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3228 bfd_zalloc for rawptr, because later on we may call free, not
3229 bfd_release, on it.
3230
3231 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3232 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3233 * cisco-core.c: New file.
3234 * Makefile.in: Change accordingly.
3235 * configure.in: Recognize cisco_core_vec.
3236 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3237 * targets.c: Add cisco_core_vec.
3238 * bfd-in2.h: Rebuilt.
3239
3240 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3241
3242 * som.h (som_copyable_section_data_struct): New structure
3243 containing all the private section information which needs
3244 to be copied from input section to output section during
3245 objcopy or strip.
3246 (som_section_data_struct): Remove several fields now in
3247 som_copyable_section_data_struct. Make the space and
3248 subspace dictionaries be pointers (to save space when
3249 only reading objects).
3250
3251 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3252 some references changed. Allocate a copyable data stucture if
3253 none exists. Store info into the copyable data structure.
3254 (bfd_som_set_subsection_attributes): Likewise.
3255 (som_is_space, som_is_subspace, som_is_container): New functions.
3256 Use these instead of directly accessing private data.
3257 (som_prep_headers): Allocate space and subspace headers here.
3258 Fill in some fields in the space/subspace headers from the
3259 copyable data.
3260 (som_bfd_copy_private_section_data): Only copy the stuff
3261 that we really need to make objcopy and strip work. Allocate
3262 the copy_data structure for the output bfd before copying.
3263
3264 * som.h (struct som_exec_data): New structure to hold exec
3265 info that must be preserved when running objcopy/strip.
3266 (struct somdata): Add new "exec_data" field and accessor
3267 macro. Add some comments on how the various fields are used.
3268 (som_section_data_struct): Make is_space and is_subspace bitfields.
3269 Delete unused subspace_index. All references now use the
3270 target_index field within the section structure itself.
3271
3272 * som.c (make_unique_section): Delete unused declaration.
3273 (som_bfd_copy_private_bfd_data): New function.
3274 (som_object_setup): Allocate space for and save exec information
3275 that needs to be copied during objcopy/strip.
3276 (som_mkobject): Do not allocate space for a file header here.
3277 It is not used when only reading SOM objects.
3278 (som_prep_headers): Allocate space for and attach a file header
3279 to the output bfd. For executables, use the saved system_id
3280 value rather than trying to guess the right value. Do not abort
3281 wwhen setting file_hdr->entry* for executables.
3282 (som_begin_writing): For executables, set the exec_entry and
3283 exec_flags fields.
3284 (som_copy_private_backend_section_data): Always return a value.
3285
3286 * libhppa.h (PA_PAGESIZE): Define.
3287
3288 * som.c (SOM_ALIGN): Define.
3289 (som_begin_writing): If writing an executable, initialize all
3290 fields in the exec header to zero. Update fields in the exec
3291 header as sizes of loadable subspaces are computed. Carefully
3292 preserve alignments when building executables. Actually write the
3293 exec after all the fields are filled in.
3294
3295 * Better long-filename handling. Reads SOM ABI compliant extended
3296 names, but doesn't quite write compliant extended names yet.
3297 * som.c (som_slurp_extended_name_table): Delete function. The
3298 generic code will handle things correctly.
3299 (som_slurp_armap): Seek to the beginning of the next member.
3300 (normalize): New function.
3301 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3302 name table into account when computing the file offsets in the
3303 SOM dictionary. Make sure to align to an even boundary.
3304 (som_write_armap): Initialize the checksum to zero.
3305 (ar_maxchars): Fix. Opps.
3306
3307 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3308
3309 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3310 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3311
3312 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3313
3314 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3315 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3316 * bfd-in2.h: Regenerated.
3317
3318 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3319 this was also named trad_unix_bfd_copy_private_bfd_data.
3320
3321 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3322
3323 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3324 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3325 returns NULL, it is not an error. It's possible that some of
3326 these checks are not necessary (because the size can never be
3327 zero), but putting in the checks is the conservative thing to do
3328 in light of the fact that some of these malloc calls replaced
3329 unchecked alloca calls, in which a zero argument would work fine.
3330
3331 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3332
3333 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3334 duplicate definition.
3335 (osf_core_bfd_is_local_label): Define.
3336
3337 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3338 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3339 failure indication, it merely means there are no relocs.
3340
3341 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3342 after NAME, since SunOS /bin/cc can't handle it.
3343
3344 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3345
3346 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3347 From sukes@glue.umd.edu (Tasuki Hirata).
3348
3349 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3350
3351 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3352 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3353 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3354
3355 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3356
3357 * som.c (som_prep_for_fixups): Detect section symbols based
3358 on either the lack of private data or the symbol flags. Do not
3359 munge section symbol names anymore -- they no longer confuse GDB.
3360 (som_begin_writing): Leave space for an exec header if writing
3361 an executable.
3362 (som_slurp_symbol_table): Recognize both forms of section symbol
3363 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3364 section symbols to be the name of the section they represent.
3365 Debugging symbols begin with "L$0\001", not just "L$".
3366
3367 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3368
3369 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3370
3371 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3372 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3373 and bfd_is_local_label.
3374
3375 * targets.c: Add new entries to the bfd_target structure.
3376
3377 * bfd.c (bfd_copy_private_bfd_data): New definition.
3378
3379 * section.c (bfd_copy_private_section_data): New definition.
3380
3381 * syms.c (bfd_is_local_label): New definition.
3382
3383 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3384
3385 * libbfd.c (bfd_generic_is_local_label): New function.
3386
3387 * *-core.c: Provide default definitions for new functions in
3388 the target vector which all point to bfd_false.
3389
3390 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3391 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3392 Default new vectors for copying private backend data to bfd_true.
3393 Default new vector for determining if a symbol is a local label
3394 to bfd_generic_is_local_label.
3395
3396 * som.c (som_bfd_copy_private_section_data): New function.
3397 (som_bfd_is_local_label): New function.
3398 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3399
3400 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3401
3402 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3403
3404 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3405
3406 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3407
3408 * Most files:
3409 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3410 Indent some of them to GNU standards.
3411
3412 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3413 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3414 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3415 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3416 Update copyright years.
3417
3418 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3419
3420 * som.c (som_prep_for_fixups): A relocation involving the section
3421 symbol for the *ABS* section is really a relocation involving
3422 no symbol.
3423 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3424 undefined symbols. Correctly distinguish between debugger symbols
3425 and section symbols.
3426
3427 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3428 for spaces and subspaces.
3429
3430 * som.c (som_bfd_count_ar_symbols): Fix typo.
3431
3432 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3433 HAS_RELOC based on the object's magic number.
3434 (make_unique_section): Delete function. BFD and its users are
3435 prepared to handle multiple sections with the same name.
3436 (setup_sections): Allocate space on the BFD's obstack to hold
3437 section names. Use bfd_make_setion_anyway rather than the
3438 obsolete make_unique_section.
3439 (som_prep_headers): Choose the correct SOM magic number based
3440 on the BFD's flags.
3441 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3442
3443 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3444
3445 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3446 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3447 * Makefile.in, configure.in: Corresponding changes.
3448
3449 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3450
3451 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3452
3453 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3454
3455 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3456 is always located at the start of the data section to allow
3457 recovery of the dynamic info from a stripped executable.
3458 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3459 and STYP_COMMENT.
3460
3461 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3462
3463 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3464 cruft (like the #pragma alloca for AIX).
3465 In addition to that problem, the C alloca calls xmalloc, which
3466 means checking for being out of memory can't work right. The
3467 following changes remove all uses of alloca from BFD.
3468 * hosts/solaris2.h: Remove alloca cruft.
3469 * som.c: Replace alloca with a fixed size auto array.
3470 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3471 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3472 sunos.c: Replace alloca with malloc and appropriate error checking and
3473 freeing.
3474 * linker.c: Replace alloca with obstack_alloc.
3475 * libbfd.h: Rebuilt.
3476
3477 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3478
3479 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3480 MIPS_R_GPREL.
3481
3482 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3483
3484 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3485 Elf*_Off typedefs by their expansion, the typedefs have been
3486 removed from include/elf/internal.h.
3487 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3488 SHT_PROGBITS section.
3489
3490 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3491
3492 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
3493
3494 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3495
3496 * configure.host: Recognize i[34]86-sequent-*.
3497
3498 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3499 return from bfd_seek indicates an error.
3500 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3501 TRAD_CORE_STACK_OFFSET.
3502 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3503 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3504
3505 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3506
3507 * som.[ch]: Do not include libhppa.h in som.c, instead include
3508 it in som.h.
3509
3510 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3511 include it in elf32-hppa.h.
3512
3513 * som.c (log2): Return -1 on error rather than aborting.
3514 (setup_sections): Bubble up an error from log2.
3515
3516 * Changes to make HP C compiler happy in both traditional
3517 and ANSI mode.
3518 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3519 field parameter.
3520 (bfd_som_set_section_attributes): Use unsigned int rather than
3521 unsigned char to avoid GNU-C extensions.
3522 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3523 or failure rather than aborting on failure.
3524
3525 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3526 som.c changes.
3527 (bfd_som_attach_aux_hdr): Add prototype.
3528 (hppa_som-gen_reloc_type): Likewise.
3529
3530 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3531 (hppa_look_for_stubs_in_section): Do not return false on failure
3532 until rest of code is ready to handle it. Abort for now.
3533
3534 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3535
3536 * bfd-in2.h: Rebuilt.
3537
3538 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
3539
3540 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
3541 * Makefile.in: delete an extra blank.
3542 * configure.in : Add i396os9k_vec.
3543
3544 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
3545
3546 * config.bfd : Add i386-os9k.
3547 * config/i386-os9k.mt : Newly add os9k target makefile.
3548
3549 * i386os9k.c : new file to handle os9k format bfd.
3550 * Makefile.in : Handle new file i386os9k.c
3551 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
3552 * cache.c : Initialize cache_sentinel to 0.
3553
3554 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3587 PARAMize and staticize rest of functions. Delete unused
3588 functions. Delete unused/unnecessary arguments to some functions.
3589 Group static vars together. Abort for bad errors until we have
3590 error code propogation working. Work on spacing and indention.
3591 Add FIXMEs for unresolved problems. Use enums rather than
3592 #defines for lots of things. Merge two functions which build
3593 linker stubs into a single function (so they can easily share a
3594 ton of common code).

3637 static vars together. Collapse common case statements together
3638 in many places. Use default case when possible instead of listing
3639 each case separately. Abort for bad errors until we get error
3640 code propogation working. Work on spacing and indention problems.
3641 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3642 COMPLEX relocation support (it's never used anyway).
3643 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3687
3688 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

3803
3804 * section.c (bfd_get_section_contents): Since this function reads
3805 unrelocated contents, the section's raw size is always the one to
3806 use for bounds checking.

3824 raw size of the input section.
3825
3826 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
3827 bout. Default with no version number is still bout. Support

3903 Make all callers of malloc or realloc (including via obstacks)
3904 check the result for NULL. Most set bfd_error to no_memory and

4570 out dynamic symbols or relocs against reloc symbols, since they
4571 are already in the .text section and we wouldn't know where to
4572 write them anyhow.

4757 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
