3041 * som.c (som_begin_writing): New approach at dealing with holes
3042 in executables left by the HP linker. Does not rely on subspace
3043 alignments as subspaces are *NOT* guaranteed to be properly
3044 aligned in an executable (can you believe that!).
3046 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3048 * som.c (som_get_section_contents): New function. Do not try

3094 required by expansions. Set s and unset h when converting a reloc
3095 from undefined to section. Change handling of PC relative relocs:
3096 if against a section, they are correct in the object file, if
3097 against an external symbol they are pcrel_offset.
3098 (mips_relax_section): New function.
3099 (mips_relax_pcrel16): New function.
3100 (ecoff_bfd_relax_section): Define.

3184 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3185 reloc, used in embedded PIC code.
3186 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
3187 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

3193 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3194 add_symbls entry point.
3196 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3197 counting relocs. Set SEC_RELOC flag for any section which has

3225 extended name table.
3227 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3229 Support for link_order types which generate relocs in order to
3230 support -Ur in the linker.
3231 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3232 from call to _bfd_generic_link_add_one_symbol.
3233 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3234 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3235 instead of bitsize to add_to_set call back.
3236 (_bfd_generic_final_link): Account for link_order relocs when
3237 allocating space for relocations. Handle them in link_order loop.
3238 (_bfd_generic_reloc_link_order): New function.

3243 argument from declaration.
3244 (_bfd_generic_reloc_link_order): Declare.

3255 (ecoff_bfd_final_link): Account for link_order relocs when
3256 allocating space for relocations. Handle them in link_order loop.
3257 (ecoff_link_write_external): Set the storage class of a defined
3258 linker created symbol based on the section it is in. Correct
3259 bfd_link_hash_weak case to use .sc rather than .st.
3260 (ecoff_reloc_link_order): New function.
3261 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3263 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3268 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3269 bfd_zmalloc. Free a pointer, not a union.
3270 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3272 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3274 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3276 * som.c (bfd_section_from_som_symbol): Only to do the value
3277 comparison for function symbols within executables.
3279 * som.c (bfd_section_from_som_symbol): Renamed from
3280 som_section_from_subspace_index. Pass in a native SOM symbol.
3281 For executables, iterate through the sections to find out
3282 which contains the symbol's address rather than using the
3283 symbol_info field. (symbol_info has a different meaning for
3284 dynamicly linked executables.)
3286 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3289 * som.c (som_begin_writing): Fix braino (one call to align
3290 space/subspace data was done unconditionally rather than
3291 just for executables.)
3293 * som.c (som_begin_writing): Align text in all executables to
3294 make HPUX kernel happy. Fixes strip/objcopy for shared
3297 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3299 * som.c (som_begin_writing): Account for alignment needs of
3300 subspaces too when writing executables. Never request a negative
3301 bss size. Fixes some problems with demand paged executables,
3302 still having problems with pure executables and shared executables.
3304 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3306 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3307 bfd_zalloc for rawptr, because later on we may call free, not
3310 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3311 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3312 * cisco-core.c: New file.
3313 * Makefile.in: Change accordingly.
3314 * configure.in: Recognize cisco_core_vec.
3315 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3316 * targets.c: Add cisco_core_vec.
3317 * bfd-in2.h: Rebuilt.
3319 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3321 * som.h (som_copyable_section_data_struct): New structure
3322 containing all the private section information which needs
3323 to be copied from input section to output section during
3325 (som_section_data_struct): Remove several fields now in
3326 som_copyable_section_data_struct. Make the space and
3327 subspace dictionaries be pointers (to save space when
3328 only reading objects).
3330 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3331 some references changed. Allocate a copyable data stucture if
3332 none exists. Store info into the copyable data structure.
3333 (bfd_som_set_subsection_attributes): Likewise.
3334 (som_is_space, som_is_subspace, som_is_container): New functions.
3335 Use these instead of directly accessing private data.
3336 (som_prep_headers): Allocate space and subspace headers here.
3337 Fill in some fields in the space/subspace headers from the
3339 (som_bfd_copy_private_section_data): Only copy the stuff
3340 that we really need to make objcopy and strip work. Allocate
3341 the copy_data structure for the output bfd before copying.
3343 * som.h (struct som_exec_data): New structure to hold exec
3344 info that must be preserved when running objcopy/strip.
3345 (struct somdata): Add new "exec_data" field and accessor
3346 macro. Add some comments on how the various fields are used.
3347 (som_section_data_struct): Make is_space and is_subspace bitfields.
3348 Delete unused subspace_index. All references now use the
3349 target_index field within the section structure itself.
3351 * som.c (make_unique_section): Delete unused declaration.
3352 (som_bfd_copy_private_bfd_data): New function.
3353 (som_object_setup): Allocate space for and save exec information
3354 that needs to be copied during objcopy/strip.
3355 (som_mkobject): Do not allocate space for a file header here.
3356 It is not used when only reading SOM objects.
3357 (som_prep_headers): Allocate space for and attach a file header
3358 to the output bfd. For executables, use the saved system_id
3359 value rather than trying to guess the right value. Do not abort
3360 wwhen setting file_hdr->entry* for executables.
3361 (som_begin_writing): For executables, set the exec_entry and
3363 (som_copy_private_backend_section_data): Always return a value.
3365 * libhppa.h (PA_PAGESIZE): Define.
3367 * som.c (SOM_ALIGN): Define.
3368 (som_begin_writing): If writing an executable, initialize all
3369 fields in the exec header to zero. Update fields in the exec
3370 header as sizes of loadable subspaces are computed. Carefully
3371 preserve alignments when building executables. Actually write the
3372 exec after all the fields are filled in.
3374 * Better long-filename handling. Reads SOM ABI compliant extended
3375 names, but doesn't quite write compliant extended names yet.
3376 * som.c (som_slurp_extended_name_table): Delete function. The
3377 generic code will handle things correctly.
3378 (som_slurp_armap): Seek to the beginning of the next member.
3379 (normalize): New function.
3380 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3381 name table into account when computing the file offsets in the
3382 SOM dictionary. Make sure to align to an even boundary.
3383 (som_write_armap): Initialize the checksum to zero.
3384 (ar_maxchars): Fix. Opps.
3386 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3388 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3389 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3391 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3393 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3394 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3395 * bfd-in2.h: Regenerated.
3397 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3398 this was also named trad_unix_bfd_copy_private_bfd_data.
3400 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3402 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3403 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3404 returns NULL, it is not an error. It's possible that some of
3405 these checks are not necessary (because the size can never be
3406 zero), but putting in the checks is the conservative thing to do
3407 in light of the fact that some of these malloc calls replaced
3408 unchecked alloca calls, in which a zero argument would work fine.
3410 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3412 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3413 duplicate definition.
3414 (osf_core_bfd_is_local_label): Define.
3416 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3417 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3418 failure indication, it merely means there are no relocs.
3420 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3421 after NAME, since SunOS /bin/cc can't handle it.
3423 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3425 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3426 From sukes@glue.umd.edu (Tasuki Hirata).
3428 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3430 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3431 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3432 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3434 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3436 * som.c (som_prep_for_fixups): Detect section symbols based
3437 on either the lack of private data or the symbol flags. Do not
3438 munge section symbol names anymore -- they no longer confuse GDB.
3439 (som_begin_writing): Leave space for an exec header if writing
3441 (som_slurp_symbol_table): Recognize both forms of section symbol
3442 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3443 section symbols to be the name of the section they represent.
3444 Debugging symbols begin with "L$0\001", not just "L$".
3446 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3448 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3450 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3451 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3452 and bfd_is_local_label.

3543 cruft (like the #pragma alloca for AIX).
3544 In addition to that problem, the C alloca calls xmalloc, which

4463 bfd_som_set_subsection_attributes): Change parameters from char
4464 to int. Following a prototype with an old-style function definition

4574 undefined, look it up in the linker hash table.
4576 * aoutx.h (translate_symbol_table): The string index 0 has a

4601 The sparc (and possibly other?) NLM format requires a different
4602 way to write exports, so add a write_export field to the backend
4603 data (and set it to NULL for everything but the sparc).
