3018 range of the bal instruction.
3019 * libecoff.h (struct ecoff_section_tdata): Define.

3023 the debugging information if it has already been read.
3024 (ecoff_indirect_link_order): Handle _cooked_size being different
3025 from _raw_size. Don't reread the contents or the relocs if they
3026 have already been read in.

3034 required by expansions. Set s and unset h when converting a reloc
3035 from undefined to section. Change handling of PC relative relocs:
3036 if against a section, they are correct in the object file, if
3037 against an external symbol they are pcrel_offset.
3038 (mips_relax_section): New function.
3039 (mips_relax_pcrel16): New function.

3124 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3125 reloc, used in embedded PIC code.
3126 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
3127 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

3133 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3134 add_symbls entry point.
3136 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3137 counting relocs. Set SEC_RELOC flag for any section which has

3145 _bfd_generic_link_add_symbols but also collect constructors and
3146 destructors by name as collect2 does.

3165 extended name table.
3167 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3169 Support for link_order types which generate relocs in order to
3170 support -Ur in the linker.
3171 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3172 from call to _bfd_generic_link_add_one_symbol.
3173 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3174 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3175 instead of bitsize to add_to_set call back.
3176 (_bfd_generic_final_link): Account for link_order relocs when
3177 allocating space for relocations. Handle them in link_order loop.
3178 (_bfd_generic_reloc_link_order): New function.

3183 argument from declaration.
3184 (_bfd_generic_reloc_link_order): Declare.

3195 (ecoff_bfd_final_link): Account for link_order relocs when
3196 allocating space for relocations. Handle them in link_order loop.
3197 (ecoff_link_write_external): Set the storage class of a defined
3198 linker created symbol based on the section it is in. Correct
3199 bfd_link_hash_weak case to use .sc rather than .st.
3200 (ecoff_reloc_link_order): New function.
3201 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3203 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3208 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3209 bfd_zmalloc. Free a pointer, not a union.
3210 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3212 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3214 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3216 * som.c (bfd_section_from_som_symbol): Only to do the value
3217 comparison for function symbols within executables.
3219 * som.c (bfd_section_from_som_symbol): Renamed from
3220 som_section_from_subspace_index. Pass in a native SOM symbol.
3221 For executables, iterate through the sections to find out
3222 which contains the symbol's address rather than using the
3223 symbol_info field. (symbol_info has a different meaning for
3224 dynamicly linked executables.)
3226 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3229 * som.c (som_begin_writing): Fix braino (one call to align
3230 space/subspace data was done unconditionally rather than
3231 just for executables.)
3233 * som.c (som_begin_writing): Align text in all executables to
3234 make HPUX kernel happy. Fixes strip/objcopy for shared
3237 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3239 * som.c (som_begin_writing): Account for alignment needs of
3240 subspaces too when writing executables. Never request a negative
3241 bss size. Fixes some problems with demand paged executables,
3242 still having problems with pure executables and shared executables.
3244 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3246 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3247 bfd_zalloc for rawptr, because later on we may call free, not
3250 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3251 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3252 * cisco-core.c: New file.
3253 * Makefile.in: Change accordingly.
3254 * configure.in: Recognize cisco_core_vec.
3255 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3256 * targets.c: Add cisco_core_vec.
3257 * bfd-in2.h: Rebuilt.
3259 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3261 * som.h (som_copyable_section_data_struct): New structure
3262 containing all the private section information which needs
3263 to be copied from input section to output section during
3265 (som_section_data_struct): Remove several fields now in
3266 som_copyable_section_data_struct. Make the space and
3267 subspace dictionaries be pointers (to save space when
3268 only reading objects).
3270 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3271 some references changed. Allocate a copyable data stucture if
3272 none exists. Store info into the copyable data structure.
3273 (bfd_som_set_subsection_attributes): Likewise.
3274 (som_is_space, som_is_subspace, som_is_container): New functions.
3275 Use these instead of directly accessing private data.
3276 (som_prep_headers): Allocate space and subspace headers here.
3277 Fill in some fields in the space/subspace headers from the
3279 (som_bfd_copy_private_section_data): Only copy the stuff
3280 that we really need to make objcopy and strip work. Allocate
3281 the copy_data structure for the output bfd before copying.
3283 * som.h (struct som_exec_data): New structure to hold exec
3284 info that must be preserved when running objcopy/strip.
3285 (struct somdata): Add new "exec_data" field and accessor
3286 macro. Add some comments on how the various fields are used.
3287 (som_section_data_struct): Make is_space and is_subspace bitfields.
3288 Delete unused subspace_index. All references now use the
3289 target_index field within the section structure itself.
3291 * som.c (make_unique_section): Delete unused declaration.
3292 (som_bfd_copy_private_bfd_data): New function.
3293 (som_object_setup): Allocate space for and save exec information
3294 that needs to be copied during objcopy/strip.
3295 (som_mkobject): Do not allocate space for a file header here.
3296 It is not used when only reading SOM objects.
3297 (som_prep_headers): Allocate space for and attach a file header
3298 to the output bfd. For executables, use the saved system_id
3299 value rather than trying to guess the right value. Do not abort
3300 wwhen setting file_hdr->entry* for executables.
3301 (som_begin_writing): For executables, set the exec_entry and
3303 (som_copy_private_backend_section_data): Always return a value.
3305 * libhppa.h (PA_PAGESIZE): Define.
3307 * som.c (SOM_ALIGN): Define.
3308 (som_begin_writing): If writing an executable, initialize all
3309 fields in the exec header to zero. Update fields in the exec
3310 header as sizes of loadable subspaces are computed. Carefully
3311 preserve alignments when building executables. Actually write the
3312 exec after all the fields are filled in.
3314 * Better long-filename handling. Reads SOM ABI compliant extended
3315 names, but doesn't quite write compliant extended names yet.
3316 * som.c (som_slurp_extended_name_table): Delete function. The
3317 generic code will handle things correctly.
3318 (som_slurp_armap): Seek to the beginning of the next member.
3319 (normalize): New function.
3320 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3321 name table into account when computing the file offsets in the
3322 SOM dictionary. Make sure to align to an even boundary.
3323 (som_write_armap): Initialize the checksum to zero.
3324 (ar_maxchars): Fix. Opps.
3326 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3328 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3329 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3331 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3333 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3334 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3335 * bfd-in2.h: Regenerated.
3337 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3338 this was also named trad_unix_bfd_copy_private_bfd_data.
3340 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3342 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3343 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3344 returns NULL, it is not an error. It's possible that some of
3345 these checks are not necessary (because the size can never be
3346 zero), but putting in the checks is the conservative thing to do
3347 in light of the fact that some of these malloc calls replaced
3348 unchecked alloca calls, in which a zero argument would work fine.
3350 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3352 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3353 duplicate definition.
3354 (osf_core_bfd_is_local_label): Define.
3356 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3357 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3358 failure indication, it merely means there are no relocs.
3360 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3361 after NAME, since SunOS /bin/cc can't handle it.
3363 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3365 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3366 From sukes@glue.umd.edu (Tasuki Hirata).
3368 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3370 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3371 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3372 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3374 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3376 * som.c (som_prep_for_fixups): Detect section symbols based
3377 on either the lack of private data or the symbol flags. Do not
3378 munge section symbol names anymore -- they no longer confuse GDB.
3379 (som_begin_writing): Leave space for an exec header if writing
3381 (som_slurp_symbol_table): Recognize both forms of section symbol
3382 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3383 section symbols to be the name of the section they represent.
3384 Debugging symbols begin with "L$0\001", not just "L$".
3386 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3388 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3390 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3391 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3392 and bfd_is_local_label.
3394 * targets.c: Add new entries to the bfd_target structure.

3410 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3411 Default new vectors for copying private backend data to bfd_true.
3412 Default new vector for determining if a symbol is a local label
3413 to bfd_generic_is_local_label.
3415 * som.c (som_bfd_copy_private_section_data): New function.
3416 (som_bfd_is_local_label): New function.
3417 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3419 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3421 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3423 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3425 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3428 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3429 Indent some of them to GNU standards.
3431 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3432 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3433 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3434 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3435 Update copyright years.
3437 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3439 * som.c (som_prep_for_fixups): A relocation involving the section
3440 symbol for the *ABS* section is really a relocation involving
3442 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3443 undefined symbols. Correctly distinguish between debugger symbols
3444 and section symbols.
3446 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3447 for spaces and subspaces.
3449 * som.c (som_bfd_count_ar_symbols): Fix typo.
3451 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3452 HAS_RELOC based on the object's magic number.
3453 (make_unique_section): Delete function. BFD and its users are
3454 prepared to handle multiple sections with the same name.
3455 (setup_sections): Allocate space on the BFD's obstack to hold
3456 section names. Use bfd_make_setion_anyway rather than the
3457 obsolete make_unique_section.
3458 (som_prep_headers): Choose the correct SOM magic number based
3460 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

3483 cruft (like the #pragma alloca for AIX).
3484 In addition to that problem, the C alloca calls xmalloc, which

4370 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
4371 (only testing for m68k and vax at the moment); do verify that the
4372 preprocessor didn't trash the arch name inside the string version.

4374 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
4376 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

4508 (get_value): If the symbol is undefined, look it up in the linker
4510 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
4511 use get_value to get the symbol value and check for undefined

4514 undefined, look it up in the linker hash table.
4516 * aoutx.h (translate_symbol_table): The string index 0 has a

4541 The sparc (and possibly other?) NLM format requires a different
4542 way to write exports, so add a write_export field to the backend
4543 data (and set it to NULL for everything but the sparc).

4704 * ecofflink.c: Extensive changes to compress and merge debugging
4705 information, and to write some of out directly rather than saving

4709 sym_filepos as well.
4710 (ecoff_get_extr): Use ifdmap instead of ifdbase.

4776 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
4777 count it as a wrong format error, not a system call error, since

4780 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
4782 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

4785 * configure.in (nlm32_alpha_vec): Set target64 to true.
4787 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4788 different, so there is no point to providing a generic one.
4789 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
4790 in the backend accessor macros; that should no longer be possible.
4791 * targets.c (target_vector): Removed nlm32_big_generic_vec,
4792 nlm64_big_generic_vec, nlm64_little_generic_vec.

5679 * elfcode.h (elf_object_p): Rather than looking through an array
5680 of architectures, get the ELF EM_xxx code from the backend
