1415 (elf32_sparc_relocate_section): When copying a reloc into a shared
1416 library, use the original addend as appropriate. Convert an

5221 comparison for function symbols within executables.
5223 * som.c (bfd_section_from_som_symbol): Renamed from
5224 som_section_from_subspace_index. Pass in a native SOM symbol.
5225 For executables, iterate through the sections to find out
5226 which contains the symbol's address rather than using the
5227 symbol_info field. (symbol_info has a different meaning for
5228 dynamicly linked executables.)
5230 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5233 * som.c (som_begin_writing): Fix braino (one call to align
5234 space/subspace data was done unconditionally rather than
5235 just for executables.)
5237 * som.c (som_begin_writing): Align text in all executables to
5238 make HPUX kernel happy. Fixes strip/objcopy for shared
5241 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5243 * som.c (som_begin_writing): Account for alignment needs of
5244 subspaces too when writing executables. Never request a negative
5245 bss size. Fixes some problems with demand paged executables,
5246 still having problems with pure executables and shared executables.
5248 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5250 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5251 bfd_zalloc for rawptr, because later on we may call free, not
5254 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5255 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5256 * cisco-core.c: New file.
5257 * Makefile.in: Change accordingly.
5258 * configure.in: Recognize cisco_core_vec.
5259 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5260 * targets.c: Add cisco_core_vec.
5261 * bfd-in2.h: Rebuilt.
5263 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5265 * som.h (som_copyable_section_data_struct): New structure
5266 containing all the private section information which needs
5267 to be copied from input section to output section during
5269 (som_section_data_struct): Remove several fields now in
5270 som_copyable_section_data_struct. Make the space and
5271 subspace dictionaries be pointers (to save space when
5272 only reading objects).
5274 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5275 some references changed. Allocate a copyable data stucture if
5276 none exists. Store info into the copyable data structure.
5277 (bfd_som_set_subsection_attributes): Likewise.
5278 (som_is_space, som_is_subspace, som_is_container): New functions.
5279 Use these instead of directly accessing private data.
5280 (som_prep_headers): Allocate space and subspace headers here.
5281 Fill in some fields in the space/subspace headers from the
5283 (som_bfd_copy_private_section_data): Only copy the stuff
5284 that we really need to make objcopy and strip work. Allocate
5285 the copy_data structure for the output bfd before copying.
5287 * som.h (struct som_exec_data): New structure to hold exec
5288 info that must be preserved when running objcopy/strip.
5289 (struct somdata): Add new "exec_data" field and accessor
5290 macro. Add some comments on how the various fields are used.
5291 (som_section_data_struct): Make is_space and is_subspace bitfields.
5292 Delete unused subspace_index. All references now use the
5293 target_index field within the section structure itself.
5295 * som.c (make_unique_section): Delete unused declaration.
5296 (som_bfd_copy_private_bfd_data): New function.
5297 (som_object_setup): Allocate space for and save exec information
5298 that needs to be copied during objcopy/strip.
5299 (som_mkobject): Do not allocate space for a file header here.
5300 It is not used when only reading SOM objects.
5301 (som_prep_headers): Allocate space for and attach a file header
5302 to the output bfd. For executables, use the saved system_id
5303 value rather than trying to guess the right value. Do not abort
5304 wwhen setting file_hdr->entry* for executables.
5305 (som_begin_writing): For executables, set the exec_entry and
5307 (som_copy_private_backend_section_data): Always return a value.
5309 * libhppa.h (PA_PAGESIZE): Define.
5311 * som.c (SOM_ALIGN): Define.
5312 (som_begin_writing): If writing an executable, initialize all
5313 fields in the exec header to zero. Update fields in the exec
5314 header as sizes of loadable subspaces are computed. Carefully
5315 preserve alignments when building executables. Actually write the
5316 exec after all the fields are filled in.
5318 * Better long-filename handling. Reads SOM ABI compliant extended
5319 names, but doesn't quite write compliant extended names yet.
5320 * som.c (som_slurp_extended_name_table): Delete function. The
5321 generic code will handle things correctly.
5322 (som_slurp_armap): Seek to the beginning of the next member.
5323 (normalize): New function.
5324 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5325 name table into account when computing the file offsets in the
5326 SOM dictionary. Make sure to align to an even boundary.
5327 (som_write_armap): Initialize the checksum to zero.
5328 (ar_maxchars): Fix. Opps.
5330 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5332 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5333 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5335 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5337 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5338 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5339 * bfd-in2.h: Regenerated.
5341 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5342 this was also named trad_unix_bfd_copy_private_bfd_data.
5344 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5346 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5347 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5348 returns NULL, it is not an error. It's possible that some of
5349 these checks are not necessary (because the size can never be
5350 zero), but putting in the checks is the conservative thing to do
5351 in light of the fact that some of these malloc calls replaced
5352 unchecked alloca calls, in which a zero argument would work fine.
5354 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5356 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5357 duplicate definition.
5358 (osf_core_bfd_is_local_label): Define.
5360 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5361 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5362 failure indication, it merely means there are no relocs.
5364 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5365 after NAME, since SunOS /bin/cc can't handle it.
5367 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5369 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5370 From sukes@glue.umd.edu (Tasuki Hirata).
5372 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5374 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5375 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5376 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5378 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5380 * som.c (som_prep_for_fixups): Detect section symbols based
5381 on either the lack of private data or the symbol flags. Do not
5382 munge section symbol names anymore -- they no longer confuse GDB.
5383 (som_begin_writing): Leave space for an exec header if writing
5385 (som_slurp_symbol_table): Recognize both forms of section symbol
5386 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5387 section symbols to be the name of the section they represent.
5388 Debugging symbols begin with "L$0\001", not just "L$".
5390 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5392 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5394 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5395 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5396 and bfd_is_local_label.
5398 * targets.c: Add new entries to the bfd_target structure.
5400 * bfd.c (bfd_copy_private_bfd_data): New definition.
5402 * section.c (bfd_copy_private_section_data): New definition.
5404 * syms.c (bfd_is_local_label): New definition.
5406 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5408 * libbfd.c (bfd_generic_is_local_label): New function.
5410 * *-core.c: Provide default definitions for new functions in
5411 the target vector which all point to bfd_false.
5413 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5414 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5415 Default new vectors for copying private backend data to bfd_true.
5416 Default new vector for determining if a symbol is a local label
5417 to bfd_generic_is_local_label.
5419 * som.c (som_bfd_copy_private_section_data): New function.
5420 (som_bfd_is_local_label): New function.
5421 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5423 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5425 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5427 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5429 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5432 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5433 Indent some of them to GNU standards.
5435 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5436 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5437 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5438 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5439 Update copyright years.
5441 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5443 * som.c (som_prep_for_fixups): A relocation involving the section
5444 symbol for the *ABS* section is really a relocation involving
5446 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5447 undefined symbols. Correctly distinguish between debugger symbols
5448 and section symbols.
5450 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5451 for spaces and subspaces.
5453 * som.c (som_bfd_count_ar_symbols): Fix typo.
5455 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5456 HAS_RELOC based on the object's magic number.
5457 (make_unique_section): Delete function. BFD and its users are
5458 prepared to handle multiple sections with the same name.
5459 (setup_sections): Allocate space on the BFD's obstack to hold
5460 section names. Use bfd_make_setion_anyway rather than the
5461 obsolete make_unique_section.
5462 (som_prep_headers): Choose the correct SOM magic number based
5464 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5466 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5468 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5469 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5470 * Makefile.in, configure.in: Corresponding changes.
5472 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5474 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5476 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5478 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5479 is always located at the start of the data section to allow
5480 recovery of the dynamic info from a stripped executable.
5481 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5484 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5486 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5487 cruft (like the #pragma alloca for AIX).
5488 In addition to that problem, the C alloca calls xmalloc, which
5489 means checking for being out of memory can't work right. The
5490 following changes remove all uses of alloca from BFD.
5491 * hosts/solaris2.h: Remove alloca cruft.
5492 * som.c: Replace alloca with a fixed size auto array.
5493 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5494 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5495 sunos.c: Replace alloca with malloc and appropriate error checking and
5497 * linker.c: Replace alloca with obstack_alloc.
5498 * libbfd.h: Rebuilt.
5500 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5502 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5505 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5507 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5508 Elf*_Off typedefs by their expansion, the typedefs have been
5509 removed from include/elf/internal.h.
5510 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5511 SHT_PROGBITS section.
5513 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5515 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5519 * configure.host: Recognize i[34]86-sequent-*.
5521 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5522 return from bfd_seek indicates an error.
5523 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5524 TRAD_CORE_STACK_OFFSET.
5525 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5526 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5528 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5530 * som.[ch]: Do not include libhppa.h in som.c, instead include
5533 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5534 include it in elf32-hppa.h.
5536 * som.c (log2): Return -1 on error rather than aborting.
5537 (setup_sections): Bubble up an error from log2.
5539 * Changes to make HP C compiler happy in both traditional
5541 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5543 (bfd_som_set_section_attributes): Use unsigned int rather than
5544 unsigned char to avoid GNU-C extensions.
5545 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5546 or failure rather than aborting on failure.
5548 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5550 (bfd_som_attach_aux_hdr): Add prototype.
5551 (hppa_som-gen_reloc_type): Likewise.
5553 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5554 (hppa_look_for_stubs_in_section): Do not return false on failure
5555 until rest of code is ready to handle it. Abort for now.
5557 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5559 * bfd-in2.h: Rebuilt.
5561 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

5570 * config/i386-os9k.mt : Newly add os9k target makefile.
5572 * i386os9k.c : new file to handle os9k format bfd.
5573 * Makefile.in : Handle new file i386os9k.c
5574 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
5575 * cache.c : Initialize cache_sentinel to 0.

5579 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5580 action in case where caller specified no argument relocation.
5581 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5582 right in the original relocation and the stub's relocation.
5584 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5585 unused symbols argument.
5587 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5588 than asymbol * for original target symbol. All callers changed.
5589 Set reloc->sym_ptr_ptr appropriately.
5590 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5591 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5592 argument. Use the output symbols when canonicalizing the relocs,
5593 creating them if necessary.
5595 * linker.c (_bfd_generic_link_output_symbols): Do not
5596 rebuild/clobber the output symbols if they already exist.
5598 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5600 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5601 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5602 * bfd-in2.h: Rebuilt.
5604 * srec.c (hex_value): Always set to a size of 256 bytes.
5605 (srec_init): Cosmetic changes.
5607 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5609 * elf32-hppa.c: Second half of major cleanup. More comments,
5610 PARAMize and staticize rest of functions. Delete unused
5611 functions. Delete unused/unnecessary arguments to some functions.
5612 Group static vars together. Abort for bad errors until we have
5613 error code propogation working. Work on spacing and indention.
5614 Add FIXMEs for unresolved problems. Use enums rather than
5615 #defines for lots of things. Merge two functions which build
5616 linker stubs into a single function (so they can easily share a
5617 ton of common code).
5619 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5621 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5622 avoid depending upon right shifts of signed numbers, and to
5623 correct handling of src_mask with lower bits zero.
5625 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5626 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

5633 (write_shdrs_and_ehdr): Make count unsigned.
5634 (assign_file_positions_for_relocs): Make i unsigned.
5635 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
5636 (section_from_elf_index): Make index argument unsigned.
5638 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
5640 * elfcode.h: Don't include assert.h.
5641 (swap_out_syms): Use BFD_ASSERT rather than assert.

5646 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
5649 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5651 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
5653 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5654 (elf_hppa_tc_make_sections): Likewise.
5655 (elf_hppa_final_processing): Add extern decl.
5657 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5658 comments. PARAMize some static functions. Delete unused functions.
5659 Delete unused/unnecessary arguments to many functions. Group
5660 static vars together. Collapse common case statements together
5661 in many places. Use default case when possible instead of listing
5662 each case separately. Abort for bad errors until we get error
5663 code propogation working. Work on spacing and indention problems.
5664 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5665 COMPLEX relocation support (it's never used anyway).
5666 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5667 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5668 (elf_hppa_tc_make_sections): Likewise.
5670 * format.c (bfd_check_format_matches): Initialize matching_vector
5671 to keep gcc -Wall quiet.
5673 * elfcode.h (elf_slurp_reloca_table): Fix typo.
5675 * som.c (som_get_symtab_upper_bound): Use "sizeof (asymbol *)"
5676 not "sizeof (som_symbol_type *)".

6407 bfd_som_set_subsection_attributes): Change parameters from char
6408 to int. Following a prototype with an old-style function definition

6511 the symbol value and check for undefined symbols.
6512 (get_value): If the symbol is undefined, look it up in the linker
6514 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6515 use get_value to get the symbol value and check for undefined
6517 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6518 undefined, look it up in the linker hash table.
6520 * aoutx.h (translate_symbol_table): The string index 0 has a

6545 The sparc (and possibly other?) NLM format requires a different
6546 way to write exports, so add a write_export field to the backend
6547 data (and set it to NULL for everything but the sparc).
