3063 * som.c (som_begin_writing): New approach at dealing with holes
3064 in executables left by the HP linker. Does not rely on subspace
3065 alignments as subspaces are *NOT* guaranteed to be properly

3068 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3070 * som.c (som_get_section_contents): New function. Do not try

3116 required by expansions. Set s and unset h when converting a reloc
3117 from undefined to section. Change handling of PC relative relocs:
3118 if against a section, they are correct in the object file, if
3119 against an external symbol they are pcrel_offset.
3120 (mips_relax_section): New function.
3121 (mips_relax_pcrel16): New function.

3206 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3207 reloc, used in embedded PIC code.
3208 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
3209 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

3215 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3216 add_symbls entry point.
3218 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3219 counting relocs. Set SEC_RELOC flag for any section which has

3247 extended name table.
3249 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3251 Support for link_order types which generate relocs in order to
3252 support -Ur in the linker.
3253 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3254 from call to _bfd_generic_link_add_one_symbol.
3255 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3256 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3257 instead of bitsize to add_to_set call back.
3258 (_bfd_generic_final_link): Account for link_order relocs when
3259 allocating space for relocations. Handle them in link_order loop.
3260 (_bfd_generic_reloc_link_order): New function.

3277 (ecoff_bfd_final_link): Account for link_order relocs when
3278 allocating space for relocations. Handle them in link_order loop.
3279 (ecoff_link_write_external): Set the storage class of a defined
3280 linker created symbol based on the section it is in. Correct
3281 bfd_link_hash_weak case to use .sc rather than .st.
3282 (ecoff_reloc_link_order): New function.
3283 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3285 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3294 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3296 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3298 * som.c (bfd_section_from_som_symbol): Only to do the value
3299 comparison for function symbols within executables.
3301 * som.c (bfd_section_from_som_symbol): Renamed from
3302 som_section_from_subspace_index. Pass in a native SOM symbol.
3303 For executables, iterate through the sections to find out
3304 which contains the symbol's address rather than using the
3305 symbol_info field. (symbol_info has a different meaning for
3306 dynamicly linked executables.)
3308 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3311 * som.c (som_begin_writing): Fix braino (one call to align
3312 space/subspace data was done unconditionally rather than
3313 just for executables.)
3315 * som.c (som_begin_writing): Align text in all executables to
3316 make HPUX kernel happy. Fixes strip/objcopy for shared
3319 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3321 * som.c (som_begin_writing): Account for alignment needs of
3322 subspaces too when writing executables. Never request a negative
3323 bss size. Fixes some problems with demand paged executables,
3324 still having problems with pure executables and shared executables.
3326 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3328 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3329 bfd_zalloc for rawptr, because later on we may call free, not
3332 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3333 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3334 * cisco-core.c: New file.
3335 * Makefile.in: Change accordingly.
3336 * configure.in: Recognize cisco_core_vec.
3337 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3338 * targets.c: Add cisco_core_vec.
3339 * bfd-in2.h: Rebuilt.
3341 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3343 * som.h (som_copyable_section_data_struct): New structure
3344 containing all the private section information which needs
3345 to be copied from input section to output section during
3347 (som_section_data_struct): Remove several fields now in
3348 som_copyable_section_data_struct. Make the space and
3349 subspace dictionaries be pointers (to save space when
3350 only reading objects).
3352 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3353 some references changed. Allocate a copyable data stucture if
3354 none exists. Store info into the copyable data structure.
3355 (bfd_som_set_subsection_attributes): Likewise.
3356 (som_is_space, som_is_subspace, som_is_container): New functions.
3357 Use these instead of directly accessing private data.
3358 (som_prep_headers): Allocate space and subspace headers here.
3359 Fill in some fields in the space/subspace headers from the
3361 (som_bfd_copy_private_section_data): Only copy the stuff
3362 that we really need to make objcopy and strip work. Allocate
3363 the copy_data structure for the output bfd before copying.
3365 * som.h (struct som_exec_data): New structure to hold exec
3366 info that must be preserved when running objcopy/strip.
3367 (struct somdata): Add new "exec_data" field and accessor
3368 macro. Add some comments on how the various fields are used.
3369 (som_section_data_struct): Make is_space and is_subspace bitfields.
3370 Delete unused subspace_index. All references now use the
3371 target_index field within the section structure itself.
3373 * som.c (make_unique_section): Delete unused declaration.
3374 (som_bfd_copy_private_bfd_data): New function.
3375 (som_object_setup): Allocate space for and save exec information
3376 that needs to be copied during objcopy/strip.
3377 (som_mkobject): Do not allocate space for a file header here.
3378 It is not used when only reading SOM objects.
3379 (som_prep_headers): Allocate space for and attach a file header
3380 to the output bfd. For executables, use the saved system_id
3381 value rather than trying to guess the right value. Do not abort
3382 wwhen setting file_hdr->entry* for executables.
3383 (som_begin_writing): For executables, set the exec_entry and
3385 (som_copy_private_backend_section_data): Always return a value.
3387 * libhppa.h (PA_PAGESIZE): Define.
3389 * som.c (SOM_ALIGN): Define.
3390 (som_begin_writing): If writing an executable, initialize all
3391 fields in the exec header to zero. Update fields in the exec
3392 header as sizes of loadable subspaces are computed. Carefully
3393 preserve alignments when building executables. Actually write the
3394 exec after all the fields are filled in.
3396 * Better long-filename handling. Reads SOM ABI compliant extended
3397 names, but doesn't quite write compliant extended names yet.
3398 * som.c (som_slurp_extended_name_table): Delete function. The
3399 generic code will handle things correctly.
3400 (som_slurp_armap): Seek to the beginning of the next member.
3401 (normalize): New function.
3402 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3403 name table into account when computing the file offsets in the
3404 SOM dictionary. Make sure to align to an even boundary.
3405 (som_write_armap): Initialize the checksum to zero.
3406 (ar_maxchars): Fix. Opps.
3408 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3410 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3411 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3413 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3415 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3416 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3417 * bfd-in2.h: Regenerated.
3419 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3420 this was also named trad_unix_bfd_copy_private_bfd_data.
3422 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3424 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3425 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3426 returns NULL, it is not an error. It's possible that some of
3427 these checks are not necessary (because the size can never be
3428 zero), but putting in the checks is the conservative thing to do
3429 in light of the fact that some of these malloc calls replaced
3430 unchecked alloca calls, in which a zero argument would work fine.
3432 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3434 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3435 duplicate definition.
3436 (osf_core_bfd_is_local_label): Define.
3438 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3439 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3440 failure indication, it merely means there are no relocs.
3442 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3443 after NAME, since SunOS /bin/cc can't handle it.
3445 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3447 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3448 From sukes@glue.umd.edu (Tasuki Hirata).
3450 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3452 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3453 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3454 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3456 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3458 * som.c (som_prep_for_fixups): Detect section symbols based
3459 on either the lack of private data or the symbol flags. Do not

4407 _bfd_generic_link_write_global_symbol): Don't require that all
4408 references to a common symbol be themselves common symbols.

4453 (only testing for m68k and vax at the moment); do verify that the
4454 preprocessor didn't trash the arch name inside the string version.

4485 bfd_som_set_subsection_attributes): Change parameters from char
4486 to int. Following a prototype with an old-style function definition

4593 use get_value to get the symbol value and check for undefined
4595 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4596 undefined, look it up in the linker hash table.
4598 * aoutx.h (translate_symbol_table): The string index 0 has a

4623 The sparc (and possibly other?) NLM format requires a different
4624 way to write exports, so add a write_export field to the backend
4625 data (and set it to NULL for everything but the sparc).
