3022 aligned in an executable (can you believe that!).
3024 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3026 * som.c (som_get_section_contents): New function. Do not try

3034 failing bfd_read, bfd_write, or bfd_seek. In a few places
3035 (like som_object_p) override the error status set by bfd_read.

3072 required by expansions. Set s and unset h when converting a reloc
3073 from undefined to section. Change handling of PC relative relocs:
3074 if against a section, they are correct in the object file, if
3075 against an external symbol they are pcrel_offset.
3076 (mips_relax_section): New function.
3077 (mips_relax_pcrel16): New function.
3078 (ecoff_bfd_relax_section): Define.

3163 reloc, used in embedded PIC code.
3164 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
3165 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

3172 add_symbls entry point.
3174 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3175 counting relocs. Set SEC_RELOC flag for any section which has

3203 extended name table.
3205 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3207 Support for link_order types which generate relocs in order to
3208 support -Ur in the linker.
3209 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3210 from call to _bfd_generic_link_add_one_symbol.
3211 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3212 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3213 instead of bitsize to add_to_set call back.
3214 (_bfd_generic_final_link): Account for link_order relocs when
3215 allocating space for relocations. Handle them in link_order loop.
3216 (_bfd_generic_reloc_link_order): New function.

3233 (ecoff_bfd_final_link): Account for link_order relocs when
3234 allocating space for relocations. Handle them in link_order loop.
3235 (ecoff_link_write_external): Set the storage class of a defined
3236 linker created symbol based on the section it is in. Correct
3237 bfd_link_hash_weak case to use .sc rather than .st.
3238 (ecoff_reloc_link_order): New function.
3239 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3241 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3246 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3247 bfd_zmalloc. Free a pointer, not a union.
3248 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3250 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3252 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3254 * som.c (bfd_section_from_som_symbol): Only to do the value
3255 comparison for function symbols within executables.
3257 * som.c (bfd_section_from_som_symbol): Renamed from
3258 som_section_from_subspace_index. Pass in a native SOM symbol.
3259 For executables, iterate through the sections to find out
3260 which contains the symbol's address rather than using the
3261 symbol_info field. (symbol_info has a different meaning for
3262 dynamicly linked executables.)
3264 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3267 * som.c (som_begin_writing): Fix braino (one call to align
3268 space/subspace data was done unconditionally rather than
3269 just for executables.)
3271 * som.c (som_begin_writing): Align text in all executables to
3272 make HPUX kernel happy. Fixes strip/objcopy for shared
3275 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3277 * som.c (som_begin_writing): Account for alignment needs of
3278 subspaces too when writing executables. Never request a negative
3279 bss size. Fixes some problems with demand paged executables,
3280 still having problems with pure executables and shared executables.
3282 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3284 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3285 bfd_zalloc for rawptr, because later on we may call free, not
3288 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3289 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3290 * cisco-core.c: New file.
3291 * Makefile.in: Change accordingly.
3292 * configure.in: Recognize cisco_core_vec.
3293 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3294 * targets.c: Add cisco_core_vec.
3295 * bfd-in2.h: Rebuilt.
3297 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3299 * som.h (som_copyable_section_data_struct): New structure
3300 containing all the private section information which needs
3301 to be copied from input section to output section during
3303 (som_section_data_struct): Remove several fields now in
3304 som_copyable_section_data_struct. Make the space and
3305 subspace dictionaries be pointers (to save space when
3306 only reading objects).
3308 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3309 some references changed. Allocate a copyable data stucture if
3310 none exists. Store info into the copyable data structure.
3311 (bfd_som_set_subsection_attributes): Likewise.
3312 (som_is_space, som_is_subspace, som_is_container): New functions.
3313 Use these instead of directly accessing private data.
3314 (som_prep_headers): Allocate space and subspace headers here.
3315 Fill in some fields in the space/subspace headers from the
3317 (som_bfd_copy_private_section_data): Only copy the stuff
3318 that we really need to make objcopy and strip work. Allocate
3319 the copy_data structure for the output bfd before copying.
3321 * som.h (struct som_exec_data): New structure to hold exec
3322 info that must be preserved when running objcopy/strip.
3323 (struct somdata): Add new "exec_data" field and accessor
3324 macro. Add some comments on how the various fields are used.
3325 (som_section_data_struct): Make is_space and is_subspace bitfields.
3326 Delete unused subspace_index. All references now use the
3327 target_index field within the section structure itself.
3329 * som.c (make_unique_section): Delete unused declaration.
3330 (som_bfd_copy_private_bfd_data): New function.
3331 (som_object_setup): Allocate space for and save exec information
3332 that needs to be copied during objcopy/strip.
3333 (som_mkobject): Do not allocate space for a file header here.
3334 It is not used when only reading SOM objects.
3335 (som_prep_headers): Allocate space for and attach a file header
3336 to the output bfd. For executables, use the saved system_id
3337 value rather than trying to guess the right value. Do not abort
3338 wwhen setting file_hdr->entry* for executables.
3339 (som_begin_writing): For executables, set the exec_entry and
3341 (som_copy_private_backend_section_data): Always return a value.
3343 * libhppa.h (PA_PAGESIZE): Define.
3345 * som.c (SOM_ALIGN): Define.
3346 (som_begin_writing): If writing an executable, initialize all
3347 fields in the exec header to zero. Update fields in the exec
3348 header as sizes of loadable subspaces are computed. Carefully
3349 preserve alignments when building executables. Actually write the
3350 exec after all the fields are filled in.
3352 * Better long-filename handling. Reads SOM ABI compliant extended
3353 names, but doesn't quite write compliant extended names yet.
3354 * som.c (som_slurp_extended_name_table): Delete function. The
3355 generic code will handle things correctly.
3356 (som_slurp_armap): Seek to the beginning of the next member.
3357 (normalize): New function.
3358 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3359 name table into account when computing the file offsets in the
3360 SOM dictionary. Make sure to align to an even boundary.
3361 (som_write_armap): Initialize the checksum to zero.
3362 (ar_maxchars): Fix. Opps.
3364 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3366 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3367 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3369 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3371 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3372 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3373 * bfd-in2.h: Regenerated.
3375 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3376 this was also named trad_unix_bfd_copy_private_bfd_data.
3378 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3380 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3381 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3382 returns NULL, it is not an error. It's possible that some of
3383 these checks are not necessary (because the size can never be
3384 zero), but putting in the checks is the conservative thing to do
3385 in light of the fact that some of these malloc calls replaced
3386 unchecked alloca calls, in which a zero argument would work fine.
3388 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3390 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3391 duplicate definition.
3392 (osf_core_bfd_is_local_label): Define.
3394 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3395 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3396 failure indication, it merely means there are no relocs.
3398 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3399 after NAME, since SunOS /bin/cc can't handle it.
3401 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3403 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3404 From sukes@glue.umd.edu (Tasuki Hirata).
3406 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3408 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3409 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3410 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3412 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3414 * som.c (som_prep_for_fixups): Detect section symbols based
3415 on either the lack of private data or the symbol flags. Do not
3416 munge section symbol names anymore -- they no longer confuse GDB.
3417 (som_begin_writing): Leave space for an exec header if writing
3419 (som_slurp_symbol_table): Recognize both forms of section symbol
3420 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3421 section symbols to be the name of the section they represent.
3422 Debugging symbols begin with "L$0\001", not just "L$".
3424 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3426 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3428 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3429 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3430 and bfd_is_local_label.
3432 * targets.c: Add new entries to the bfd_target structure.
3434 * bfd.c (bfd_copy_private_bfd_data): New definition.

3445 the target vector which all point to bfd_false.
3447 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3448 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3449 Default new vectors for copying private backend data to bfd_true.
3450 Default new vector for determining if a symbol is a local label
3451 to bfd_generic_is_local_label.
3453 * som.c (som_bfd_copy_private_section_data): New function.
3454 (som_bfd_is_local_label): New function.
3455 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3457 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3459 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

3521 cruft (like the #pragma alloca for AIX).
3522 In addition to that problem, the C alloca calls xmalloc, which

4579 The sparc (and possibly other?) NLM format requires a different
4580 way to write exports, so add a write_export field to the backend
4581 data (and set it to NULL for everything but the sparc).
