3022 required by expansions. Set s and unset h when converting a reloc
3023 from undefined to section. Change handling of PC relative relocs:
3024 if against a section, they are correct in the object file, if
3025 against an external symbol they are pcrel_offset.

3155 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3157 Support for link_order types which generate relocs in order to
3158 support -Ur in the linker.
3159 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3160 from call to _bfd_generic_link_add_one_symbol.
3161 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3162 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3163 instead of bitsize to add_to_set call back.
3164 (_bfd_generic_final_link): Account for link_order relocs when
3165 allocating space for relocations. Handle them in link_order loop.

3184 allocating space for relocations. Handle them in link_order loop.
3185 (ecoff_link_write_external): Set the storage class of a defined
3186 linker created symbol based on the section it is in. Correct
3187 bfd_link_hash_weak case to use .sc rather than .st.
3188 (ecoff_reloc_link_order): New function.
3189 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

3200 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3202 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3204 * som.c (bfd_section_from_som_symbol): Only to do the value
3205 comparison for function symbols within executables.
3207 * som.c (bfd_section_from_som_symbol): Renamed from
3208 som_section_from_subspace_index. Pass in a native SOM symbol.
3209 For executables, iterate through the sections to find out
3210 which contains the symbol's address rather than using the
3211 symbol_info field. (symbol_info has a different meaning for
3212 dynamicly linked executables.)
3214 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3217 * som.c (som_begin_writing): Fix braino (one call to align
3218 space/subspace data was done unconditionally rather than
3219 just for executables.)
3221 * som.c (som_begin_writing): Align text in all executables to
3222 make HPUX kernel happy. Fixes strip/objcopy for shared
3225 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3227 * som.c (som_begin_writing): Account for alignment needs of
3228 subspaces too when writing executables. Never request a negative
3229 bss size. Fixes some problems with demand paged executables,
3230 still having problems with pure executables and shared executables.
3232 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3234 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3235 bfd_zalloc for rawptr, because later on we may call free, not
3238 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3239 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3240 * cisco-core.c: New file.

3247 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3249 * som.h (som_copyable_section_data_struct): New structure
3250 containing all the private section information which needs
3251 to be copied from input section to output section during
3253 (som_section_data_struct): Remove several fields now in
3254 som_copyable_section_data_struct. Make the space and
3255 subspace dictionaries be pointers (to save space when
3256 only reading objects).
3258 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3259 some references changed. Allocate a copyable data stucture if
3260 none exists. Store info into the copyable data structure.
3261 (bfd_som_set_subsection_attributes): Likewise.
3262 (som_is_space, som_is_subspace, som_is_container): New functions.
3263 Use these instead of directly accessing private data.
3264 (som_prep_headers): Allocate space and subspace headers here.
3265 Fill in some fields in the space/subspace headers from the
3267 (som_bfd_copy_private_section_data): Only copy the stuff
3268 that we really need to make objcopy and strip work. Allocate
3269 the copy_data structure for the output bfd before copying.
3271 * som.h (struct som_exec_data): New structure to hold exec
3272 info that must be preserved when running objcopy/strip.
3273 (struct somdata): Add new "exec_data" field and accessor
3274 macro. Add some comments on how the various fields are used.
3275 (som_section_data_struct): Make is_space and is_subspace bitfields.
3276 Delete unused subspace_index. All references now use the
3277 target_index field within the section structure itself.
3279 * som.c (make_unique_section): Delete unused declaration.
3280 (som_bfd_copy_private_bfd_data): New function.
3281 (som_object_setup): Allocate space for and save exec information
3282 that needs to be copied during objcopy/strip.
3283 (som_mkobject): Do not allocate space for a file header here.
3284 It is not used when only reading SOM objects.
3285 (som_prep_headers): Allocate space for and attach a file header
3286 to the output bfd. For executables, use the saved system_id
3287 value rather than trying to guess the right value. Do not abort
3288 wwhen setting file_hdr->entry* for executables.
3289 (som_begin_writing): For executables, set the exec_entry and
3291 (som_copy_private_backend_section_data): Always return a value.
3293 * libhppa.h (PA_PAGESIZE): Define.
3295 * som.c (SOM_ALIGN): Define.
3296 (som_begin_writing): If writing an executable, initialize all
3297 fields in the exec header to zero. Update fields in the exec
3298 header as sizes of loadable subspaces are computed. Carefully
3299 preserve alignments when building executables. Actually write the
3300 exec after all the fields are filled in.
3302 * Better long-filename handling. Reads SOM ABI compliant extended
3303 names, but doesn't quite write compliant extended names yet.
3304 * som.c (som_slurp_extended_name_table): Delete function. The
3305 generic code will handle things correctly.
3306 (som_slurp_armap): Seek to the beginning of the next member.
3307 (normalize): New function.
3308 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3309 name table into account when computing the file offsets in the
3310 SOM dictionary. Make sure to align to an even boundary.
3311 (som_write_armap): Initialize the checksum to zero.
3312 (ar_maxchars): Fix. Opps.

3316 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3317 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3319 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3321 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3322 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3323 * bfd-in2.h: Regenerated.
3325 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3326 this was also named trad_unix_bfd_copy_private_bfd_data.
3328 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3330 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3331 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3332 returns NULL, it is not an error. It's possible that some of
3333 these checks are not necessary (because the size can never be
3334 zero), but putting in the checks is the conservative thing to do
3335 in light of the fact that some of these malloc calls replaced
3336 unchecked alloca calls, in which a zero argument would work fine.
3338 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3340 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3341 duplicate definition.
3342 (osf_core_bfd_is_local_label): Define.
3344 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3345 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3346 failure indication, it merely means there are no relocs.
3348 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3349 after NAME, since SunOS /bin/cc can't handle it.
3351 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3353 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3354 From sukes@glue.umd.edu (Tasuki Hirata).
3356 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3358 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3359 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3360 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3362 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3364 * som.c (som_prep_for_fixups): Detect section symbols based
3365 on either the lack of private data or the symbol flags. Do not
3366 munge section symbol names anymore -- they no longer confuse GDB.
3367 (som_begin_writing): Leave space for an exec header if writing
3369 (som_slurp_symbol_table): Recognize both forms of section symbol
3370 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3371 section symbols to be the name of the section they represent.
3372 Debugging symbols begin with "L$0\001", not just "L$".
3374 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3376 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3378 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3379 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3380 and bfd_is_local_label.
3382 * targets.c: Add new entries to the bfd_target structure.

3398 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3399 Default new vectors for copying private backend data to bfd_true.
3400 Default new vector for determining if a symbol is a local label
3401 to bfd_generic_is_local_label.
3403 * som.c (som_bfd_copy_private_section_data): New function.
3404 (som_bfd_is_local_label): New function.
3405 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3407 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3409 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3411 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3413 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3416 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3417 Indent some of them to GNU standards.
3419 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3420 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

3422 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3423 Update copyright years.
3425 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3427 * som.c (som_prep_for_fixups): A relocation involving the section
3428 symbol for the *ABS* section is really a relocation involving
3430 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3431 undefined symbols. Correctly distinguish between debugger symbols
3432 and section symbols.
3434 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3435 for spaces and subspaces.
3437 * som.c (som_bfd_count_ar_symbols): Fix typo.
3439 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3440 HAS_RELOC based on the object's magic number.
3441 (make_unique_section): Delete function. BFD and its users are
3442 prepared to handle multiple sections with the same name.
3443 (setup_sections): Allocate space on the BFD's obstack to hold
3444 section names. Use bfd_make_setion_anyway rather than the
3445 obsolete make_unique_section.
3446 (som_prep_headers): Choose the correct SOM magic number based
3448 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

3471 cruft (like the #pragma alloca for AIX).
3472 In addition to that problem, the C alloca calls xmalloc, which
3473 means checking for being out of memory can't work right. The
3474 following changes remove all uses of alloca from BFD.

3823 that will actually be retained.
3824 (b_out_relax_section): If a section contains no relocations, don't
3825 bother processing them.
3826 (b_out_get_relocated_section_contents): Set reloc_done. Assert
3827 that bfd_get_section_contents returns true. Check that relocs are

3830 that reloc->addend falls between the current source offset and the
3831 raw size of the input section.

3910 Make all callers of malloc or realloc (including via obstacks)
3911 check the result for NULL. Most set bfd_error to no_memory and
3912 return in that case; a few are harder to fix, and are marked

4359 (only testing for m68k and vax at the moment); do verify that the
4360 preprocessor didn't trash the arch name inside the string version.

4502 undefined, look it up in the linker hash table.
4504 * aoutx.h (translate_symbol_table): The string index 0 has a

4529 The sparc (and possibly other?) NLM format requires a different
4530 way to write exports, so add a write_export field to the backend
4531 data (and set it to NULL for everything but the sparc).

4697 sym_filepos as well.
4698 (ecoff_get_extr): Use ifdmap instead of ifdbase.

4768 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
4770 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

4773 * configure.in (nlm32_alpha_vec): Set target64 to true.
4775 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4776 different, so there is no point to providing a generic one.
4777 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
4778 in the backend accessor macros; that should no longer be possible.
4779 * targets.c (target_vector): Removed nlm32_big_generic_vec,
4780 nlm64_big_generic_vec, nlm64_little_generic_vec.

5668 of architectures, get the ELF EM_xxx code from the backend
5669 information. Let the generic ELF target match any EM_xxx code not
5670 matched by another ELF target. Call elf_backend_object_p to let
5671 the backend do more checks and set global information.
5672 * libelf.h (struct elf_backend_data): Added elf_machine_code and
5673 elf_backend_object_p fields.
5674 (struct bfd_elf_arch_map): Removed.

5676 * elf32-target.h, elf64-target.h: Initialize elf_machine_code
5677 field with ELF_MACHINE_CODE. Initialize elf_backend_object_p
5678 field with elf_backend_object_p (if it is defined).

5695 * elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
5696 for R_MIPS_26. Correct overflow detection requires matching the
5697 upper four bits of the destination against the PC. From Ted Lemon
5698 <mellon@pepper.ncd.com>.
5700 * bout.c (b_out_reloc_type_lookup): Return type should point to
5702 * coff-i960.c (coff_i960_reloc_type_lookup): Likewise.
5703 * elf32-hppa.c (elf_hppa_reloc_type_lookup): Likewise.

5710 field. Removed unused write_relocs field.
5711 * elf32-target.h: Adjusted elf_backend_data initialization
5713 * elf64-target.h: Corrected elf_backend_data initialization to
5714 fill in all fields and to set elf_64_p to 1.
5716 Mon Nov 8 18:13:14 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
