3051 from undefined to section. Change handling of PC relative relocs:
3052 if against a section, they are correct in the object file, if
3053 against an external symbol they are pcrel_offset.

3141 reloc, used in embedded PIC code.
3142 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3181 extended name table.
3183 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3185 Support for link_order types which generate relocs in order to
3186 support -Ur in the linker.
3187 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3188 from call to _bfd_generic_link_add_one_symbol.
3189 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3190 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3191 instead of bitsize to add_to_set call back.
3192 (_bfd_generic_final_link): Account for link_order relocs when
3193 allocating space for relocations. Handle them in link_order loop.
3194 (_bfd_generic_reloc_link_order): New function.

3212 allocating space for relocations. Handle them in link_order loop.
3213 (ecoff_link_write_external): Set the storage class of a defined
3214 linker created symbol based on the section it is in. Correct
3215 bfd_link_hash_weak case to use .sc rather than .st.
3216 (ecoff_reloc_link_order): New function.
3217 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3219 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3224 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3225 bfd_zmalloc. Free a pointer, not a union.
3226 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3228 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3230 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3232 * som.c (bfd_section_from_som_symbol): Only to do the value
3233 comparison for function symbols within executables.
3235 * som.c (bfd_section_from_som_symbol): Renamed from
3236 som_section_from_subspace_index. Pass in a native SOM symbol.
3237 For executables, iterate through the sections to find out
3238 which contains the symbol's address rather than using the
3239 symbol_info field. (symbol_info has a different meaning for
3240 dynamicly linked executables.)
3242 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3245 * som.c (som_begin_writing): Fix braino (one call to align
3246 space/subspace data was done unconditionally rather than
3247 just for executables.)
3249 * som.c (som_begin_writing): Align text in all executables to
3250 make HPUX kernel happy. Fixes strip/objcopy for shared
3253 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3255 * som.c (som_begin_writing): Account for alignment needs of
3256 subspaces too when writing executables. Never request a negative
3257 bss size. Fixes some problems with demand paged executables,
3258 still having problems with pure executables and shared executables.
3260 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3262 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3263 bfd_zalloc for rawptr, because later on we may call free, not
3266 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3267 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3268 * cisco-core.c: New file.
3269 * Makefile.in: Change accordingly.
3270 * configure.in: Recognize cisco_core_vec.
3271 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.

3275 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3277 * som.h (som_copyable_section_data_struct): New structure
3278 containing all the private section information which needs
3279 to be copied from input section to output section during
3281 (som_section_data_struct): Remove several fields now in
3282 som_copyable_section_data_struct. Make the space and
3283 subspace dictionaries be pointers (to save space when
3284 only reading objects).
3286 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3287 some references changed. Allocate a copyable data stucture if
3288 none exists. Store info into the copyable data structure.
3289 (bfd_som_set_subsection_attributes): Likewise.
3290 (som_is_space, som_is_subspace, som_is_container): New functions.
3291 Use these instead of directly accessing private data.
3292 (som_prep_headers): Allocate space and subspace headers here.
3293 Fill in some fields in the space/subspace headers from the
3295 (som_bfd_copy_private_section_data): Only copy the stuff
3296 that we really need to make objcopy and strip work. Allocate
3297 the copy_data structure for the output bfd before copying.
3299 * som.h (struct som_exec_data): New structure to hold exec
3300 info that must be preserved when running objcopy/strip.
3301 (struct somdata): Add new "exec_data" field and accessor
3302 macro. Add some comments on how the various fields are used.
3303 (som_section_data_struct): Make is_space and is_subspace bitfields.
3304 Delete unused subspace_index. All references now use the
3305 target_index field within the section structure itself.
3307 * som.c (make_unique_section): Delete unused declaration.
3308 (som_bfd_copy_private_bfd_data): New function.
3309 (som_object_setup): Allocate space for and save exec information
3310 that needs to be copied during objcopy/strip.
3311 (som_mkobject): Do not allocate space for a file header here.
3312 It is not used when only reading SOM objects.
3313 (som_prep_headers): Allocate space for and attach a file header
3314 to the output bfd. For executables, use the saved system_id
3315 value rather than trying to guess the right value. Do not abort
3316 wwhen setting file_hdr->entry* for executables.
3317 (som_begin_writing): For executables, set the exec_entry and
3319 (som_copy_private_backend_section_data): Always return a value.
3321 * libhppa.h (PA_PAGESIZE): Define.
3323 * som.c (SOM_ALIGN): Define.
3324 (som_begin_writing): If writing an executable, initialize all
3325 fields in the exec header to zero. Update fields in the exec
3326 header as sizes of loadable subspaces are computed. Carefully
3327 preserve alignments when building executables. Actually write the
3328 exec after all the fields are filled in.
3330 * Better long-filename handling. Reads SOM ABI compliant extended
3331 names, but doesn't quite write compliant extended names yet.
3332 * som.c (som_slurp_extended_name_table): Delete function. The
3333 generic code will handle things correctly.
3334 (som_slurp_armap): Seek to the beginning of the next member.
3335 (normalize): New function.
3336 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3337 name table into account when computing the file offsets in the
3338 SOM dictionary. Make sure to align to an even boundary.
3339 (som_write_armap): Initialize the checksum to zero.
3340 (ar_maxchars): Fix. Opps.
3342 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3344 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3345 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3347 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3349 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3350 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3351 * bfd-in2.h: Regenerated.
3353 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3354 this was also named trad_unix_bfd_copy_private_bfd_data.
3356 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3358 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3359 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3360 returns NULL, it is not an error. It's possible that some of
3361 these checks are not necessary (because the size can never be
3362 zero), but putting in the checks is the conservative thing to do
3363 in light of the fact that some of these malloc calls replaced
3364 unchecked alloca calls, in which a zero argument would work fine.
3366 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3368 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3369 duplicate definition.
3370 (osf_core_bfd_is_local_label): Define.
3372 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3373 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3374 failure indication, it merely means there are no relocs.
3376 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3377 after NAME, since SunOS /bin/cc can't handle it.
3379 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3381 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3382 From sukes@glue.umd.edu (Tasuki Hirata).
3384 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3386 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3387 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3388 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3390 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3392 * som.c (som_prep_for_fixups): Detect section symbols based
3393 on either the lack of private data or the symbol flags. Do not
3394 munge section symbol names anymore -- they no longer confuse GDB.
3395 (som_begin_writing): Leave space for an exec header if writing
3397 (som_slurp_symbol_table): Recognize both forms of section symbol
3398 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3399 section symbols to be the name of the section they represent.
3400 Debugging symbols begin with "L$0\001", not just "L$".
3402 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3404 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3406 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3407 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3408 and bfd_is_local_label.
3410 * targets.c: Add new entries to the bfd_target structure.

3423 the target vector which all point to bfd_false.
3425 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3426 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3427 Default new vectors for copying private backend data to bfd_true.
3428 Default new vector for determining if a symbol is a local label
3429 to bfd_generic_is_local_label.
3431 * som.c (som_bfd_copy_private_section_data): New function.
3432 (som_bfd_is_local_label): New function.
3433 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3435 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3437 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3439 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3441 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3444 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3445 Indent some of them to GNU standards.
3447 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3448 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

3450 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3451 Update copyright years.
3453 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3455 * som.c (som_prep_for_fixups): A relocation involving the section
3456 symbol for the *ABS* section is really a relocation involving

3499 cruft (like the #pragma alloca for AIX).
3500 In addition to that problem, the C alloca calls xmalloc, which

4557 The sparc (and possibly other?) NLM format requires a different
4558 way to write exports, so add a write_export field to the backend
4559 data (and set it to NULL for everything but the sparc).
