1655 an empty .plt section.
1656 (elf32_sparc_relocate_section): For a GOT reloc against a global
1657 symbol when no dynamic object was seen, initialize the contents of
1658 the .got section. For a GOT reloc against a local symbol, only

1678 storage class slightly more verbose. It's not clear how many
1679 characters I can justify using up, but before this change they

5225 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5227 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
5228 for first character in an extended name.
5229 (_bfd_write_archive_contents): If ar_padchar == '/', then use
5230 "//" as the name of the special archive member holding the
5231 extended name table.
5233 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5235 Support for link_order types which generate relocs in order to
5236 support -Ur in the linker.
5237 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5238 from call to _bfd_generic_link_add_one_symbol.
5239 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5240 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5241 instead of bitsize to add_to_set call back.
5242 (_bfd_generic_final_link): Account for link_order relocs when
5243 allocating space for relocations. Handle them in link_order loop.
5244 (_bfd_generic_reloc_link_order): New function.
5245 (_bfd_default_link_order): If a reloc_link_order is seen here,
5247 (_bfd_count_link_order_relocs): New function.
5248 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5249 argument from declaration.
5250 (_bfd_generic_reloc_link_order): Declare.
5251 (_bfd_count_link_order_relocs): Declare.
5252 * libbfd.h: Rebuilt.
5253 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5254 call to _bfd_generic_link_add_one_symbol.
5255 (NAME(aout,final_link)): Account for link_order relocs when
5256 allocating space for relocations. Handle them after handling all
5258 (aout_link_reloc_link_order): New function.
5259 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
5260 call to _bfd_generic_link_add_one_symbol.
5261 (ecoff_bfd_final_link): Account for link_order relocs when
5262 allocating space for relocations. Handle them in link_order loop.
5263 (ecoff_link_write_external): Set the storage class of a defined
5264 linker created symbol based on the section it is in. Correct
5265 bfd_link_hash_weak case to use .sc rather than .st.
5266 (ecoff_reloc_link_order): New function.
5267 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5269 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5271 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5274 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5275 bfd_zmalloc. Free a pointer, not a union.
5276 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5278 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5280 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5282 * som.c (bfd_section_from_som_symbol): Only to do the value
5283 comparison for function symbols within executables.
5285 * som.c (bfd_section_from_som_symbol): Renamed from
5286 som_section_from_subspace_index. Pass in a native SOM symbol.
5287 For executables, iterate through the sections to find out
5288 which contains the symbol's address rather than using the
5289 symbol_info field. (symbol_info has a different meaning for
5290 dynamicly linked executables.)
5292 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5295 * som.c (som_begin_writing): Fix braino (one call to align
5296 space/subspace data was done unconditionally rather than
5297 just for executables.)
5299 * som.c (som_begin_writing): Align text in all executables to
5300 make HPUX kernel happy. Fixes strip/objcopy for shared
5303 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5305 * som.c (som_begin_writing): Account for alignment needs of
5306 subspaces too when writing executables. Never request a negative
5307 bss size. Fixes some problems with demand paged executables,
5308 still having problems with pure executables and shared executables.
5310 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5312 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5313 bfd_zalloc for rawptr, because later on we may call free, not
5316 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5317 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5318 * cisco-core.c: New file.
5319 * Makefile.in: Change accordingly.
5320 * configure.in: Recognize cisco_core_vec.
5321 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5322 * targets.c: Add cisco_core_vec.
5323 * bfd-in2.h: Rebuilt.
5325 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5327 * som.h (som_copyable_section_data_struct): New structure
5328 containing all the private section information which needs
5329 to be copied from input section to output section during
5331 (som_section_data_struct): Remove several fields now in
5332 som_copyable_section_data_struct. Make the space and
5333 subspace dictionaries be pointers (to save space when
5334 only reading objects).
5336 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5337 some references changed. Allocate a copyable data stucture if
5338 none exists. Store info into the copyable data structure.
5339 (bfd_som_set_subsection_attributes): Likewise.
5340 (som_is_space, som_is_subspace, som_is_container): New functions.
5341 Use these instead of directly accessing private data.
5342 (som_prep_headers): Allocate space and subspace headers here.
5343 Fill in some fields in the space/subspace headers from the
5345 (som_bfd_copy_private_section_data): Only copy the stuff
5346 that we really need to make objcopy and strip work. Allocate
5347 the copy_data structure for the output bfd before copying.
5349 * som.h (struct som_exec_data): New structure to hold exec
5350 info that must be preserved when running objcopy/strip.
5351 (struct somdata): Add new "exec_data" field and accessor
5352 macro. Add some comments on how the various fields are used.
5353 (som_section_data_struct): Make is_space and is_subspace bitfields.
5354 Delete unused subspace_index. All references now use the
5355 target_index field within the section structure itself.
5357 * som.c (make_unique_section): Delete unused declaration.
5358 (som_bfd_copy_private_bfd_data): New function.
5359 (som_object_setup): Allocate space for and save exec information
5360 that needs to be copied during objcopy/strip.
5361 (som_mkobject): Do not allocate space for a file header here.
5362 It is not used when only reading SOM objects.
5363 (som_prep_headers): Allocate space for and attach a file header
5364 to the output bfd. For executables, use the saved system_id
5365 value rather than trying to guess the right value. Do not abort
5366 wwhen setting file_hdr->entry* for executables.
5367 (som_begin_writing): For executables, set the exec_entry and
5369 (som_copy_private_backend_section_data): Always return a value.
5371 * libhppa.h (PA_PAGESIZE): Define.
5373 * som.c (SOM_ALIGN): Define.
5374 (som_begin_writing): If writing an executable, initialize all
5375 fields in the exec header to zero. Update fields in the exec
5376 header as sizes of loadable subspaces are computed. Carefully
5377 preserve alignments when building executables. Actually write the
5378 exec after all the fields are filled in.
5380 * Better long-filename handling. Reads SOM ABI compliant extended
5381 names, but doesn't quite write compliant extended names yet.
5382 * som.c (som_slurp_extended_name_table): Delete function. The
5383 generic code will handle things correctly.
5384 (som_slurp_armap): Seek to the beginning of the next member.
5385 (normalize): New function.
5386 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5387 name table into account when computing the file offsets in the
5388 SOM dictionary. Make sure to align to an even boundary.
5389 (som_write_armap): Initialize the checksum to zero.
5390 (ar_maxchars): Fix. Opps.
5392 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5394 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5395 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5397 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5399 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5400 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5401 * bfd-in2.h: Regenerated.
5403 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5404 this was also named trad_unix_bfd_copy_private_bfd_data.
5406 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5408 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5409 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5410 returns NULL, it is not an error. It's possible that some of
5411 these checks are not necessary (because the size can never be
5412 zero), but putting in the checks is the conservative thing to do
5413 in light of the fact that some of these malloc calls replaced
5414 unchecked alloca calls, in which a zero argument would work fine.
5416 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5418 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5419 duplicate definition.
5420 (osf_core_bfd_is_local_label): Define.
5422 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5423 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5424 failure indication, it merely means there are no relocs.
5426 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5427 after NAME, since SunOS /bin/cc can't handle it.
5429 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5431 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5432 From sukes@glue.umd.edu (Tasuki Hirata).
5434 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5436 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5437 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5438 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5440 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5442 * som.c (som_prep_for_fixups): Detect section symbols based
5443 on either the lack of private data or the symbol flags. Do not
5444 munge section symbol names anymore -- they no longer confuse GDB.
5445 (som_begin_writing): Leave space for an exec header if writing
5447 (som_slurp_symbol_table): Recognize both forms of section symbol
5448 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5449 section symbols to be the name of the section they represent.
5450 Debugging symbols begin with "L$0\001", not just "L$".
5452 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5454 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5456 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5457 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5458 and bfd_is_local_label.
5460 * targets.c: Add new entries to the bfd_target structure.
5462 * bfd.c (bfd_copy_private_bfd_data): New definition.
5464 * section.c (bfd_copy_private_section_data): New definition.
5466 * syms.c (bfd_is_local_label): New definition.
5468 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5470 * libbfd.c (bfd_generic_is_local_label): New function.
5472 * *-core.c: Provide default definitions for new functions in
5473 the target vector which all point to bfd_false.
5475 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5476 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5477 Default new vectors for copying private backend data to bfd_true.
5478 Default new vector for determining if a symbol is a local label
5479 to bfd_generic_is_local_label.
5481 * som.c (som_bfd_copy_private_section_data): New function.
5482 (som_bfd_is_local_label): New function.
5483 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5485 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5487 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5489 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5491 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5494 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5495 Indent some of them to GNU standards.
5497 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5498 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5499 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5500 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5501 Update copyright years.
5503 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5505 * som.c (som_prep_for_fixups): A relocation involving the section
5506 symbol for the *ABS* section is really a relocation involving
5508 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5509 undefined symbols. Correctly distinguish between debugger symbols
5510 and section symbols.
5512 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5513 for spaces and subspaces.
5515 * som.c (som_bfd_count_ar_symbols): Fix typo.
5517 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5518 HAS_RELOC based on the object's magic number.
5519 (make_unique_section): Delete function. BFD and its users are
5520 prepared to handle multiple sections with the same name.
5521 (setup_sections): Allocate space on the BFD's obstack to hold
5522 section names. Use bfd_make_setion_anyway rather than the
5523 obsolete make_unique_section.
5524 (som_prep_headers): Choose the correct SOM magic number based
5526 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5528 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5530 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5531 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5532 * Makefile.in, configure.in: Corresponding changes.

5536 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5538 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5540 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5541 is always located at the start of the data section to allow
5542 recovery of the dynamic info from a stripped executable.
5543 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5546 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5548 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5549 cruft (like the #pragma alloca for AIX).
5550 In addition to that problem, the C alloca calls xmalloc, which
5551 means checking for being out of memory can't work right. The
5552 following changes remove all uses of alloca from BFD.
5553 * hosts/solaris2.h: Remove alloca cruft.
5554 * som.c: Replace alloca with a fixed size auto array.
5555 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

5557 sunos.c: Replace alloca with malloc and appropriate error checking and
5559 * linker.c: Replace alloca with obstack_alloc.
5560 * libbfd.h: Rebuilt.
5562 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5564 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5567 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5569 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5570 Elf*_Off typedefs by their expansion, the typedefs have been
5571 removed from include/elf/internal.h.
5572 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5573 SHT_PROGBITS section.
5575 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5577 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5581 * configure.host: Recognize i[34]86-sequent-*.
5583 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5584 return from bfd_seek indicates an error.
5585 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5586 TRAD_CORE_STACK_OFFSET.
5587 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5588 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5590 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5592 * som.[ch]: Do not include libhppa.h in som.c, instead include
5595 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5596 include it in elf32-hppa.h.
5598 * som.c (log2): Return -1 on error rather than aborting.
5599 (setup_sections): Bubble up an error from log2.
5601 * Changes to make HP C compiler happy in both traditional
5603 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5605 (bfd_som_set_section_attributes): Use unsigned int rather than
5606 unsigned char to avoid GNU-C extensions.
5607 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5608 or failure rather than aborting on failure.
5610 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5612 (bfd_som_attach_aux_hdr): Add prototype.
5613 (hppa_som-gen_reloc_type): Likewise.
5615 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5616 (hppa_look_for_stubs_in_section): Do not return false on failure
5617 until rest of code is ready to handle it. Abort for now.
5619 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5621 * bfd-in2.h: Rebuilt.
5623 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

5632 * config/i386-os9k.mt : Newly add os9k target makefile.
5634 * i386os9k.c : new file to handle os9k format bfd.
5635 * Makefile.in : Handle new file i386os9k.c
5636 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.

5641 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5642 action in case where caller specified no argument relocation.
5643 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5644 right in the original relocation and the stub's relocation.
5646 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5647 unused symbols argument.
5649 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5650 than asymbol * for original target symbol. All callers changed.
5651 Set reloc->sym_ptr_ptr appropriately.
5652 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5653 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5654 argument. Use the output symbols when canonicalizing the relocs,
5655 creating them if necessary.
5657 * linker.c (_bfd_generic_link_output_symbols): Do not
5658 rebuild/clobber the output symbols if they already exist.
5660 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5662 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5663 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5664 * bfd-in2.h: Rebuilt.
5666 * srec.c (hex_value): Always set to a size of 256 bytes.
5667 (srec_init): Cosmetic changes.
5669 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5671 * elf32-hppa.c: Second half of major cleanup. More comments,
5672 PARAMize and staticize rest of functions. Delete unused
5673 functions. Delete unused/unnecessary arguments to some functions.
5674 Group static vars together. Abort for bad errors until we have
5675 error code propogation working. Work on spacing and indention.
5676 Add FIXMEs for unresolved problems. Use enums rather than

5903 bother processing them.
5904 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5988 Make all callers of malloc or realloc (including via obstacks)
5989 check the result for NULL. Most set bfd_error to no_memory and

7877 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
7878 BFD_RELOC_MIPS_LITERAL.
7879 * elf32-mips.c (mips_reloc_map): Handle new relocs.
7880 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
7883 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
7884 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
7885 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
7886 MY_bfd_seclet_link): Define.
7887 (MY_bfd_reloc_type_lookup): Rename from
7888 MY_reloc_howto_type_lookup.
7889 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
7890 (MY(vec)): Use JUMP_TABLE rather than listing functions.
7891 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
7892 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
7893 terms of MY, because that causes a recusive invocation of CAT when
7894 expanded within JUMP_TABLE, and ANSI compilers don't expand
7896 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
7897 MY_reloc_howto_type_lookup, and don't define in terms of MY.
7898 (MY_canonicalize_reloc): Don't define in terms of MY.
7899 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
7900 than listing functions.
