1609 an empty .plt section.
1610 (elf32_sparc_relocate_section): For a GOT reloc against a global
1611 symbol when no dynamic object was seen, initialize the contents of
1612 the .got section. For a GOT reloc against a local symbol, only

1614 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1615 create a PLT entry as a R_SPARC_WDISP30 reloc.

1632 storage class slightly more verbose. It's not clear how many
1633 characters I can justify using up, but before this change they

5219 bfd_link_hash_weak case to use .sc rather than .st.
5220 (ecoff_reloc_link_order): New function.
5221 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5223 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5225 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5228 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5229 bfd_zmalloc. Free a pointer, not a union.
5230 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5232 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5234 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5236 * som.c (bfd_section_from_som_symbol): Only to do the value
5237 comparison for function symbols within executables.
5239 * som.c (bfd_section_from_som_symbol): Renamed from
5240 som_section_from_subspace_index. Pass in a native SOM symbol.
5241 For executables, iterate through the sections to find out
5242 which contains the symbol's address rather than using the
5243 symbol_info field. (symbol_info has a different meaning for
5244 dynamicly linked executables.)
5246 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5249 * som.c (som_begin_writing): Fix braino (one call to align
5250 space/subspace data was done unconditionally rather than
5251 just for executables.)
5253 * som.c (som_begin_writing): Align text in all executables to
5254 make HPUX kernel happy. Fixes strip/objcopy for shared
5257 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5259 * som.c (som_begin_writing): Account for alignment needs of
5260 subspaces too when writing executables. Never request a negative
5261 bss size. Fixes some problems with demand paged executables,
5262 still having problems with pure executables and shared executables.
5264 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5266 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5267 bfd_zalloc for rawptr, because later on we may call free, not
5270 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5271 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5272 * cisco-core.c: New file.
5273 * Makefile.in: Change accordingly.
5274 * configure.in: Recognize cisco_core_vec.
5275 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5276 * targets.c: Add cisco_core_vec.
5277 * bfd-in2.h: Rebuilt.
5279 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5281 * som.h (som_copyable_section_data_struct): New structure
5282 containing all the private section information which needs
5283 to be copied from input section to output section during
5285 (som_section_data_struct): Remove several fields now in
5286 som_copyable_section_data_struct. Make the space and
5287 subspace dictionaries be pointers (to save space when
5288 only reading objects).
5290 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5291 some references changed. Allocate a copyable data stucture if
5292 none exists. Store info into the copyable data structure.
5293 (bfd_som_set_subsection_attributes): Likewise.
5294 (som_is_space, som_is_subspace, som_is_container): New functions.
5295 Use these instead of directly accessing private data.
5296 (som_prep_headers): Allocate space and subspace headers here.
5297 Fill in some fields in the space/subspace headers from the
5299 (som_bfd_copy_private_section_data): Only copy the stuff
5300 that we really need to make objcopy and strip work. Allocate
5301 the copy_data structure for the output bfd before copying.
5303 * som.h (struct som_exec_data): New structure to hold exec
5304 info that must be preserved when running objcopy/strip.
5305 (struct somdata): Add new "exec_data" field and accessor
5306 macro. Add some comments on how the various fields are used.
5307 (som_section_data_struct): Make is_space and is_subspace bitfields.
5308 Delete unused subspace_index. All references now use the
5309 target_index field within the section structure itself.
5311 * som.c (make_unique_section): Delete unused declaration.
5312 (som_bfd_copy_private_bfd_data): New function.
5313 (som_object_setup): Allocate space for and save exec information
5314 that needs to be copied during objcopy/strip.
5315 (som_mkobject): Do not allocate space for a file header here.
5316 It is not used when only reading SOM objects.
5317 (som_prep_headers): Allocate space for and attach a file header
5318 to the output bfd. For executables, use the saved system_id
5319 value rather than trying to guess the right value. Do not abort
5320 wwhen setting file_hdr->entry* for executables.
5321 (som_begin_writing): For executables, set the exec_entry and
5323 (som_copy_private_backend_section_data): Always return a value.
5325 * libhppa.h (PA_PAGESIZE): Define.
5327 * som.c (SOM_ALIGN): Define.
5328 (som_begin_writing): If writing an executable, initialize all
5329 fields in the exec header to zero. Update fields in the exec
5330 header as sizes of loadable subspaces are computed. Carefully
5331 preserve alignments when building executables. Actually write the
5332 exec after all the fields are filled in.
5334 * Better long-filename handling. Reads SOM ABI compliant extended
5335 names, but doesn't quite write compliant extended names yet.
5336 * som.c (som_slurp_extended_name_table): Delete function. The
5337 generic code will handle things correctly.
5338 (som_slurp_armap): Seek to the beginning of the next member.
5339 (normalize): New function.
5340 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5341 name table into account when computing the file offsets in the
5342 SOM dictionary. Make sure to align to an even boundary.
5343 (som_write_armap): Initialize the checksum to zero.
5344 (ar_maxchars): Fix. Opps.
5346 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5348 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5349 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5351 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5353 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5354 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5355 * bfd-in2.h: Regenerated.
5357 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5358 this was also named trad_unix_bfd_copy_private_bfd_data.
5360 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5362 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5363 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5364 returns NULL, it is not an error. It's possible that some of
5365 these checks are not necessary (because the size can never be
5366 zero), but putting in the checks is the conservative thing to do
5367 in light of the fact that some of these malloc calls replaced
5368 unchecked alloca calls, in which a zero argument would work fine.
5370 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5372 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5373 duplicate definition.
5374 (osf_core_bfd_is_local_label): Define.
5376 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5377 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5378 failure indication, it merely means there are no relocs.
5380 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5381 after NAME, since SunOS /bin/cc can't handle it.
5383 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5385 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5386 From sukes@glue.umd.edu (Tasuki Hirata).
5388 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5390 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5391 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5392 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5394 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5396 * som.c (som_prep_for_fixups): Detect section symbols based
5397 on either the lack of private data or the symbol flags. Do not
5398 munge section symbol names anymore -- they no longer confuse GDB.
5399 (som_begin_writing): Leave space for an exec header if writing
5401 (som_slurp_symbol_table): Recognize both forms of section symbol
5402 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5403 section symbols to be the name of the section they represent.
5404 Debugging symbols begin with "L$0\001", not just "L$".
5406 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5408 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5410 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5411 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5412 and bfd_is_local_label.
5414 * targets.c: Add new entries to the bfd_target structure.
5416 * bfd.c (bfd_copy_private_bfd_data): New definition.
5418 * section.c (bfd_copy_private_section_data): New definition.
5420 * syms.c (bfd_is_local_label): New definition.
5422 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5424 * libbfd.c (bfd_generic_is_local_label): New function.
5426 * *-core.c: Provide default definitions for new functions in
5427 the target vector which all point to bfd_false.
5429 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5430 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5431 Default new vectors for copying private backend data to bfd_true.
5432 Default new vector for determining if a symbol is a local label
5433 to bfd_generic_is_local_label.
5435 * som.c (som_bfd_copy_private_section_data): New function.
5436 (som_bfd_is_local_label): New function.
5437 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5439 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5441 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5443 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5445 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5448 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5449 Indent some of them to GNU standards.
5451 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5452 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5453 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5454 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5455 Update copyright years.
5457 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5459 * som.c (som_prep_for_fixups): A relocation involving the section
5460 symbol for the *ABS* section is really a relocation involving
5462 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5463 undefined symbols. Correctly distinguish between debugger symbols
5464 and section symbols.
5466 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5467 for spaces and subspaces.
5469 * som.c (som_bfd_count_ar_symbols): Fix typo.
5471 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5472 HAS_RELOC based on the object's magic number.
5473 (make_unique_section): Delete function. BFD and its users are
5474 prepared to handle multiple sections with the same name.
5475 (setup_sections): Allocate space on the BFD's obstack to hold
5476 section names. Use bfd_make_setion_anyway rather than the
5477 obsolete make_unique_section.
5478 (som_prep_headers): Choose the correct SOM magic number based
5480 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5482 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5484 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5485 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5486 * Makefile.in, configure.in: Corresponding changes.
5488 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5490 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5492 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5494 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5495 is always located at the start of the data section to allow
5496 recovery of the dynamic info from a stripped executable.
5497 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5500 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5502 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5503 cruft (like the #pragma alloca for AIX).
5504 In addition to that problem, the C alloca calls xmalloc, which
5505 means checking for being out of memory can't work right. The
5506 following changes remove all uses of alloca from BFD.
5507 * hosts/solaris2.h: Remove alloca cruft.
5508 * som.c: Replace alloca with a fixed size auto array.
5509 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5510 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5511 sunos.c: Replace alloca with malloc and appropriate error checking and
5513 * linker.c: Replace alloca with obstack_alloc.
5514 * libbfd.h: Rebuilt.
5516 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5518 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5521 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5523 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5524 Elf*_Off typedefs by their expansion, the typedefs have been
5525 removed from include/elf/internal.h.
5526 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5527 SHT_PROGBITS section.
5529 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5531 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5537 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5538 return from bfd_seek indicates an error.
5539 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5540 TRAD_CORE_STACK_OFFSET.
5541 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5542 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5544 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5546 * som.[ch]: Do not include libhppa.h in som.c, instead include
5549 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5550 include it in elf32-hppa.h.
5552 * som.c (log2): Return -1 on error rather than aborting.
5553 (setup_sections): Bubble up an error from log2.
5555 * Changes to make HP C compiler happy in both traditional
5557 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5559 (bfd_som_set_section_attributes): Use unsigned int rather than
5560 unsigned char to avoid GNU-C extensions.
5561 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5562 or failure rather than aborting on failure.
5564 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5566 (bfd_som_attach_aux_hdr): Add prototype.
5567 (hppa_som-gen_reloc_type): Likewise.
5569 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5570 (hppa_look_for_stubs_in_section): Do not return false on failure
5571 until rest of code is ready to handle it. Abort for now.

5575 * bfd-in2.h: Rebuilt.
5577 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

5586 * config/i386-os9k.mt : Newly add os9k target makefile.
5588 * i386os9k.c : new file to handle os9k format bfd.
5589 * Makefile.in : Handle new file i386os9k.c
5590 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
5591 * cache.c : Initialize cache_sentinel to 0.

5595 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5596 action in case where caller specified no argument relocation.
5597 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5598 right in the original relocation and the stub's relocation.
5600 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5601 unused symbols argument.
5603 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5604 than asymbol * for original target symbol. All callers changed.
5605 Set reloc->sym_ptr_ptr appropriately.
5606 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5607 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5608 argument. Use the output symbols when canonicalizing the relocs,
5609 creating them if necessary.
5611 * linker.c (_bfd_generic_link_output_symbols): Do not
5612 rebuild/clobber the output symbols if they already exist.
5614 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5616 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5617 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5618 * bfd-in2.h: Rebuilt.
5620 * srec.c (hex_value): Always set to a size of 256 bytes.
5621 (srec_init): Cosmetic changes.
5623 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5625 * elf32-hppa.c: Second half of major cleanup. More comments,
5626 PARAMize and staticize rest of functions. Delete unused
5627 functions. Delete unused/unnecessary arguments to some functions.
5628 Group static vars together. Abort for bad errors until we have
5629 error code propogation working. Work on spacing and indention.
5630 Add FIXMEs for unresolved problems. Use enums rather than
5631 #defines for lots of things. Merge two functions which build
5632 linker stubs into a single function (so they can easily share a
5633 ton of common code).
5635 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5637 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5638 avoid depending upon right shifts of signed numbers, and to
5639 correct handling of src_mask with lower bits zero.
5641 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5642 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

5652 (section_from_elf_index): Make index argument unsigned.
5654 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
5656 * elfcode.h: Don't include assert.h.

5667 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
5669 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5670 (elf_hppa_tc_make_sections): Likewise.
5671 (elf_hppa_final_processing): Add extern decl.
5673 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5674 comments. PARAMize some static functions. Delete unused functions.
5675 Delete unused/unnecessary arguments to many functions. Group
5676 static vars together. Collapse common case statements together
5677 in many places. Use default case when possible instead of listing

6531 use get_value to get the symbol value and check for undefined
6533 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6534 undefined, look it up in the linker hash table.
6536 * aoutx.h (translate_symbol_table): The string index 0 has a

6561 The sparc (and possibly other?) NLM format requires a different
6562 way to write exports, so add a write_export field to the backend
