3052 * som.c (som_begin_writing): New approach at dealing with holes
3053 in executables left by the HP linker. Does not rely on subspace
3054 alignments as subspaces are *NOT* guaranteed to be properly

3057 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3059 * som.c (som_get_section_contents): New function. Do not try

3105 required by expansions. Set s and unset h when converting a reloc
3106 from undefined to section. Change handling of PC relative relocs:
3107 if against a section, they are correct in the object file, if
3108 against an external symbol they are pcrel_offset.
3109 (mips_relax_section): New function.
3110 (mips_relax_pcrel16): New function.

3196 reloc, used in embedded PIC code.
3197 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
3198 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

3204 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3205 add_symbls entry point.
3207 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3208 counting relocs. Set SEC_RELOC flag for any section which has

3236 extended name table.
3238 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3240 Support for link_order types which generate relocs in order to
3241 support -Ur in the linker.
3242 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3243 from call to _bfd_generic_link_add_one_symbol.
3244 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3245 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3246 instead of bitsize to add_to_set call back.
3247 (_bfd_generic_final_link): Account for link_order relocs when
3248 allocating space for relocations. Handle them in link_order loop.
3249 (_bfd_generic_reloc_link_order): New function.

3254 argument from declaration.
3255 (_bfd_generic_reloc_link_order): Declare.

3266 (ecoff_bfd_final_link): Account for link_order relocs when
3267 allocating space for relocations. Handle them in link_order loop.
3268 (ecoff_link_write_external): Set the storage class of a defined
3269 linker created symbol based on the section it is in. Correct
3270 bfd_link_hash_weak case to use .sc rather than .st.
3271 (ecoff_reloc_link_order): New function.
3272 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3274 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3280 bfd_zmalloc. Free a pointer, not a union.
3281 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3283 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3285 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3287 * som.c (bfd_section_from_som_symbol): Only to do the value
3288 comparison for function symbols within executables.
3290 * som.c (bfd_section_from_som_symbol): Renamed from
3291 som_section_from_subspace_index. Pass in a native SOM symbol.
3292 For executables, iterate through the sections to find out
3293 which contains the symbol's address rather than using the
3294 symbol_info field. (symbol_info has a different meaning for
3295 dynamicly linked executables.)
3297 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3300 * som.c (som_begin_writing): Fix braino (one call to align
3301 space/subspace data was done unconditionally rather than
3302 just for executables.)
3304 * som.c (som_begin_writing): Align text in all executables to
3305 make HPUX kernel happy. Fixes strip/objcopy for shared
3308 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3310 * som.c (som_begin_writing): Account for alignment needs of
3311 subspaces too when writing executables. Never request a negative
3312 bss size. Fixes some problems with demand paged executables,
3313 still having problems with pure executables and shared executables.
3315 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3317 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3318 bfd_zalloc for rawptr, because later on we may call free, not
3321 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3322 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3323 * cisco-core.c: New file.
3324 * Makefile.in: Change accordingly.
3325 * configure.in: Recognize cisco_core_vec.
3326 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3327 * targets.c: Add cisco_core_vec.
3328 * bfd-in2.h: Rebuilt.
3330 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3332 * som.h (som_copyable_section_data_struct): New structure
3333 containing all the private section information which needs
3334 to be copied from input section to output section during
3336 (som_section_data_struct): Remove several fields now in
3337 som_copyable_section_data_struct. Make the space and
3338 subspace dictionaries be pointers (to save space when
3339 only reading objects).
3341 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3342 some references changed. Allocate a copyable data stucture if
3343 none exists. Store info into the copyable data structure.
3344 (bfd_som_set_subsection_attributes): Likewise.
3345 (som_is_space, som_is_subspace, som_is_container): New functions.
3346 Use these instead of directly accessing private data.
3347 (som_prep_headers): Allocate space and subspace headers here.
3348 Fill in some fields in the space/subspace headers from the
3350 (som_bfd_copy_private_section_data): Only copy the stuff
3351 that we really need to make objcopy and strip work. Allocate
3352 the copy_data structure for the output bfd before copying.
3354 * som.h (struct som_exec_data): New structure to hold exec
3355 info that must be preserved when running objcopy/strip.
3356 (struct somdata): Add new "exec_data" field and accessor
3357 macro. Add some comments on how the various fields are used.
3358 (som_section_data_struct): Make is_space and is_subspace bitfields.
3359 Delete unused subspace_index. All references now use the
3360 target_index field within the section structure itself.
3362 * som.c (make_unique_section): Delete unused declaration.
3363 (som_bfd_copy_private_bfd_data): New function.
3364 (som_object_setup): Allocate space for and save exec information
3365 that needs to be copied during objcopy/strip.
3366 (som_mkobject): Do not allocate space for a file header here.
3367 It is not used when only reading SOM objects.
3368 (som_prep_headers): Allocate space for and attach a file header
3369 to the output bfd. For executables, use the saved system_id
3370 value rather than trying to guess the right value. Do not abort
3371 wwhen setting file_hdr->entry* for executables.
3372 (som_begin_writing): For executables, set the exec_entry and
3374 (som_copy_private_backend_section_data): Always return a value.
3376 * libhppa.h (PA_PAGESIZE): Define.
3378 * som.c (SOM_ALIGN): Define.
3379 (som_begin_writing): If writing an executable, initialize all
3380 fields in the exec header to zero. Update fields in the exec
3381 header as sizes of loadable subspaces are computed. Carefully
3382 preserve alignments when building executables. Actually write the
3383 exec after all the fields are filled in.
3385 * Better long-filename handling. Reads SOM ABI compliant extended
3386 names, but doesn't quite write compliant extended names yet.
3387 * som.c (som_slurp_extended_name_table): Delete function. The
3388 generic code will handle things correctly.
3389 (som_slurp_armap): Seek to the beginning of the next member.
3390 (normalize): New function.
3391 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3392 name table into account when computing the file offsets in the
3393 SOM dictionary. Make sure to align to an even boundary.
3394 (som_write_armap): Initialize the checksum to zero.
3395 (ar_maxchars): Fix. Opps.
3397 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3399 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3400 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3402 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3404 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3405 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3406 * bfd-in2.h: Regenerated.
3408 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3409 this was also named trad_unix_bfd_copy_private_bfd_data.
3411 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3413 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3414 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3415 returns NULL, it is not an error. It's possible that some of
3416 these checks are not necessary (because the size can never be
3417 zero), but putting in the checks is the conservative thing to do
3418 in light of the fact that some of these malloc calls replaced
3419 unchecked alloca calls, in which a zero argument would work fine.
3421 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3423 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3424 duplicate definition.
3425 (osf_core_bfd_is_local_label): Define.
3427 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3428 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3429 failure indication, it merely means there are no relocs.
3431 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3432 after NAME, since SunOS /bin/cc can't handle it.
3434 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3436 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3437 From sukes@glue.umd.edu (Tasuki Hirata).
3439 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3441 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3442 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3443 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3445 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3447 * som.c (som_prep_for_fixups): Detect section symbols based
3448 on either the lack of private data or the symbol flags. Do not
3449 munge section symbol names anymore -- they no longer confuse GDB.
3450 (som_begin_writing): Leave space for an exec header if writing
3452 (som_slurp_symbol_table): Recognize both forms of section symbol
3453 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"

4474 bfd_som_set_subsection_attributes): Change parameters from char
4475 to int. Following a prototype with an old-style function definition

4585 undefined, look it up in the linker hash table.
4587 * aoutx.h (translate_symbol_table): The string index 0 has a

4612 The sparc (and possibly other?) NLM format requires a different
4613 way to write exports, so add a write_export field to the backend
4614 data (and set it to NULL for everything but the sparc).
