1597 an empty .plt section.
1598 (elf32_sparc_relocate_section): For a GOT reloc against a global
1599 symbol when no dynamic object was seen, initialize the contents of
1600 the .got section. For a GOT reloc against a local symbol, only

5220 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5222 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5224 * som.c (bfd_section_from_som_symbol): Only to do the value
5225 comparison for function symbols within executables.
5227 * som.c (bfd_section_from_som_symbol): Renamed from
5228 som_section_from_subspace_index. Pass in a native SOM symbol.
5229 For executables, iterate through the sections to find out
5230 which contains the symbol's address rather than using the
5231 symbol_info field. (symbol_info has a different meaning for
5232 dynamicly linked executables.)
5234 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5237 * som.c (som_begin_writing): Fix braino (one call to align
5238 space/subspace data was done unconditionally rather than
5239 just for executables.)
5241 * som.c (som_begin_writing): Align text in all executables to
5242 make HPUX kernel happy. Fixes strip/objcopy for shared
5245 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5247 * som.c (som_begin_writing): Account for alignment needs of
5248 subspaces too when writing executables. Never request a negative
5249 bss size. Fixes some problems with demand paged executables,
5250 still having problems with pure executables and shared executables.
5252 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5254 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5255 bfd_zalloc for rawptr, because later on we may call free, not
5258 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5259 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5260 * cisco-core.c: New file.
5261 * Makefile.in: Change accordingly.
5262 * configure.in: Recognize cisco_core_vec.
5263 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5264 * targets.c: Add cisco_core_vec.
5265 * bfd-in2.h: Rebuilt.
5267 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5269 * som.h (som_copyable_section_data_struct): New structure
5270 containing all the private section information which needs
5271 to be copied from input section to output section during
5273 (som_section_data_struct): Remove several fields now in
5274 som_copyable_section_data_struct. Make the space and
5275 subspace dictionaries be pointers (to save space when
5276 only reading objects).
5278 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5279 some references changed. Allocate a copyable data stucture if
5280 none exists. Store info into the copyable data structure.
5281 (bfd_som_set_subsection_attributes): Likewise.
5282 (som_is_space, som_is_subspace, som_is_container): New functions.
5283 Use these instead of directly accessing private data.
5284 (som_prep_headers): Allocate space and subspace headers here.
5285 Fill in some fields in the space/subspace headers from the
5287 (som_bfd_copy_private_section_data): Only copy the stuff
5288 that we really need to make objcopy and strip work. Allocate
5289 the copy_data structure for the output bfd before copying.
5291 * som.h (struct som_exec_data): New structure to hold exec
5292 info that must be preserved when running objcopy/strip.
5293 (struct somdata): Add new "exec_data" field and accessor
5294 macro. Add some comments on how the various fields are used.
5295 (som_section_data_struct): Make is_space and is_subspace bitfields.
5296 Delete unused subspace_index. All references now use the
5297 target_index field within the section structure itself.
5299 * som.c (make_unique_section): Delete unused declaration.
5300 (som_bfd_copy_private_bfd_data): New function.
5301 (som_object_setup): Allocate space for and save exec information
5302 that needs to be copied during objcopy/strip.
5303 (som_mkobject): Do not allocate space for a file header here.
5304 It is not used when only reading SOM objects.
5305 (som_prep_headers): Allocate space for and attach a file header
5306 to the output bfd. For executables, use the saved system_id
5307 value rather than trying to guess the right value. Do not abort
5308 wwhen setting file_hdr->entry* for executables.
5309 (som_begin_writing): For executables, set the exec_entry and
5311 (som_copy_private_backend_section_data): Always return a value.
5313 * libhppa.h (PA_PAGESIZE): Define.
5315 * som.c (SOM_ALIGN): Define.
5316 (som_begin_writing): If writing an executable, initialize all
5317 fields in the exec header to zero. Update fields in the exec
5318 header as sizes of loadable subspaces are computed. Carefully
5319 preserve alignments when building executables. Actually write the
5320 exec after all the fields are filled in.
5322 * Better long-filename handling. Reads SOM ABI compliant extended
5323 names, but doesn't quite write compliant extended names yet.
5324 * som.c (som_slurp_extended_name_table): Delete function. The
5325 generic code will handle things correctly.
5326 (som_slurp_armap): Seek to the beginning of the next member.
5327 (normalize): New function.
5328 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5329 name table into account when computing the file offsets in the
5330 SOM dictionary. Make sure to align to an even boundary.
5331 (som_write_armap): Initialize the checksum to zero.
5332 (ar_maxchars): Fix. Opps.
5334 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5336 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5337 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5339 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5341 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5342 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5343 * bfd-in2.h: Regenerated.
5345 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5346 this was also named trad_unix_bfd_copy_private_bfd_data.
5348 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5350 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5351 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5352 returns NULL, it is not an error. It's possible that some of
5353 these checks are not necessary (because the size can never be
5354 zero), but putting in the checks is the conservative thing to do
5355 in light of the fact that some of these malloc calls replaced
5356 unchecked alloca calls, in which a zero argument would work fine.
5358 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5360 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5361 duplicate definition.
5362 (osf_core_bfd_is_local_label): Define.
5364 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5365 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5366 failure indication, it merely means there are no relocs.
5368 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5369 after NAME, since SunOS /bin/cc can't handle it.
5371 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5373 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5374 From sukes@glue.umd.edu (Tasuki Hirata).
5376 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5378 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5379 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5380 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5382 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5384 * som.c (som_prep_for_fixups): Detect section symbols based
5385 on either the lack of private data or the symbol flags. Do not
5386 munge section symbol names anymore -- they no longer confuse GDB.
5387 (som_begin_writing): Leave space for an exec header if writing
5389 (som_slurp_symbol_table): Recognize both forms of section symbol
5390 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5391 section symbols to be the name of the section they represent.
5392 Debugging symbols begin with "L$0\001", not just "L$".
5394 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5396 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5398 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5399 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5400 and bfd_is_local_label.
5402 * targets.c: Add new entries to the bfd_target structure.
5404 * bfd.c (bfd_copy_private_bfd_data): New definition.
5406 * section.c (bfd_copy_private_section_data): New definition.
5408 * syms.c (bfd_is_local_label): New definition.
5410 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5412 * libbfd.c (bfd_generic_is_local_label): New function.
5414 * *-core.c: Provide default definitions for new functions in
5415 the target vector which all point to bfd_false.
5417 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5418 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5419 Default new vectors for copying private backend data to bfd_true.
5420 Default new vector for determining if a symbol is a local label
5421 to bfd_generic_is_local_label.
5423 * som.c (som_bfd_copy_private_section_data): New function.
5424 (som_bfd_is_local_label): New function.
5425 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5427 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5429 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5431 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5433 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5436 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5437 Indent some of them to GNU standards.
5439 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5440 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5441 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5442 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5443 Update copyright years.
5445 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5447 * som.c (som_prep_for_fixups): A relocation involving the section
5448 symbol for the *ABS* section is really a relocation involving
5450 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5451 undefined symbols. Correctly distinguish between debugger symbols
5452 and section symbols.
5454 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5455 for spaces and subspaces.
5457 * som.c (som_bfd_count_ar_symbols): Fix typo.
5459 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5460 HAS_RELOC based on the object's magic number.
5461 (make_unique_section): Delete function. BFD and its users are
5462 prepared to handle multiple sections with the same name.
5463 (setup_sections): Allocate space on the BFD's obstack to hold
5464 section names. Use bfd_make_setion_anyway rather than the
5465 obsolete make_unique_section.
5466 (som_prep_headers): Choose the correct SOM magic number based
5468 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5470 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5472 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5473 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5474 * Makefile.in, configure.in: Corresponding changes.
5476 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5478 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5480 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5482 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5483 is always located at the start of the data section to allow
5484 recovery of the dynamic info from a stripped executable.
5485 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5488 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5490 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5491 cruft (like the #pragma alloca for AIX).
5492 In addition to that problem, the C alloca calls xmalloc, which
5493 means checking for being out of memory can't work right. The
5494 following changes remove all uses of alloca from BFD.
5495 * hosts/solaris2.h: Remove alloca cruft.
5496 * som.c: Replace alloca with a fixed size auto array.
5497 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5498 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5499 sunos.c: Replace alloca with malloc and appropriate error checking and
5501 * linker.c: Replace alloca with obstack_alloc.
5502 * libbfd.h: Rebuilt.
5504 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5506 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5509 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5511 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5512 Elf*_Off typedefs by their expansion, the typedefs have been
5513 removed from include/elf/internal.h.
5514 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5515 SHT_PROGBITS section.
5517 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5519 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5523 * configure.host: Recognize i[34]86-sequent-*.
5525 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5526 return from bfd_seek indicates an error.
5527 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5528 TRAD_CORE_STACK_OFFSET.
5529 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5530 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5532 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5534 * som.[ch]: Do not include libhppa.h in som.c, instead include
5537 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5538 include it in elf32-hppa.h.
5540 * som.c (log2): Return -1 on error rather than aborting.
5541 (setup_sections): Bubble up an error from log2.
5543 * Changes to make HP C compiler happy in both traditional
5545 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5547 (bfd_som_set_section_attributes): Use unsigned int rather than
5548 unsigned char to avoid GNU-C extensions.
5549 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5550 or failure rather than aborting on failure.
5552 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5554 (bfd_som_attach_aux_hdr): Add prototype.
5555 (hppa_som-gen_reloc_type): Likewise.
5557 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5558 (hppa_look_for_stubs_in_section): Do not return false on failure
5559 until rest of code is ready to handle it. Abort for now.
5561 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5563 * bfd-in2.h: Rebuilt.
5565 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
5567 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

5571 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
5573 * config.bfd : Add i386-os9k.
5574 * config/i386-os9k.mt : Newly add os9k target makefile.
5576 * i386os9k.c : new file to handle os9k format bfd.
5577 * Makefile.in : Handle new file i386os9k.c
5578 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
5579 * cache.c : Initialize cache_sentinel to 0.

5583 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5584 action in case where caller specified no argument relocation.
5585 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5586 right in the original relocation and the stub's relocation.
5588 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5589 unused symbols argument.
5591 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5592 than asymbol * for original target symbol. All callers changed.
5593 Set reloc->sym_ptr_ptr appropriately.
5594 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5595 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5596 argument. Use the output symbols when canonicalizing the relocs,
5597 creating them if necessary.
5599 * linker.c (_bfd_generic_link_output_symbols): Do not
5600 rebuild/clobber the output symbols if they already exist.
5602 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5604 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5605 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5606 * bfd-in2.h: Rebuilt.
5608 * srec.c (hex_value): Always set to a size of 256 bytes.
5609 (srec_init): Cosmetic changes.
5611 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5613 * elf32-hppa.c: Second half of major cleanup. More comments,
5614 PARAMize and staticize rest of functions. Delete unused
5615 functions. Delete unused/unnecessary arguments to some functions.
5616 Group static vars together. Abort for bad errors until we have
5617 error code propogation working. Work on spacing and indention.
5618 Add FIXMEs for unresolved problems. Use enums rather than
5619 #defines for lots of things. Merge two functions which build
5620 linker stubs into a single function (so they can easily share a
5621 ton of common code).
5623 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5625 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5626 avoid depending upon right shifts of signed numbers, and to
5627 correct handling of src_mask with lower bits zero.
5629 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5630 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

5637 (write_shdrs_and_ehdr): Make count unsigned.
5638 (assign_file_positions_for_relocs): Make i unsigned.
5639 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
5640 (section_from_elf_index): Make index argument unsigned.
5642 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
5644 * elfcode.h: Don't include assert.h.
5645 (swap_out_syms): Use BFD_ASSERT rather than assert.
5647 * linker.c (_bfd_generic_link_write_global_symbol): Add missing
5650 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
5653 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5655 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
5657 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5658 (elf_hppa_tc_make_sections): Likewise.
5659 (elf_hppa_final_processing): Add extern decl.
5661 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5662 comments. PARAMize some static functions. Delete unused functions.
5663 Delete unused/unnecessary arguments to many functions. Group
5664 static vars together. Collapse common case statements together
5665 in many places. Use default case when possible instead of listing
5666 each case separately. Abort for bad errors until we get error
5667 code propogation working. Work on spacing and indention problems.
5668 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5669 COMPLEX relocation support (it's never used anyway).
5670 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5671 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5672 (elf_hppa_tc_make_sections): Likewise.
5674 * format.c (bfd_check_format_matches): Initialize matching_vector

6516 (get_value): If the symbol is undefined, look it up in the linker
6518 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6519 use get_value to get the symbol value and check for undefined
6521 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6522 undefined, look it up in the linker hash table.
6524 * aoutx.h (translate_symbol_table): The string index 0 has a

6549 The sparc (and possibly other?) NLM format requires a different
6550 way to write exports, so add a write_export field to the backend
6551 data (and set it to NULL for everything but the sparc).
