2472 (elf32_sparc_size_dynamic_sections): When generating a shared
2473 library, allocate space for a dynamic symbol for each output
2474 section, storing the index in the dynindx field of the ELF section
2475 data. Adjust the other dynindx fields to account for this.
2476 (elf32_sparc_adjust_dynindx): New static function.
2477 (elf32_sparc_relocate_section): When copying a reloc into a shared

2594 set dynobj.
2595 (elf_link_create_dynamic_sections): If dynamic sections were
2596 already created, don't do anything. If dynobj is already set, use
2597 it; otherwise, set it to the bfd argument. Don't initialize

2614 (elf_i386_check_relocs): Just call elf_i386_create_got_section if
2615 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
2616 Only create the .rel.got section, and only make space for a reloc,
2617 for a global symbol or when generating a shared object. For a
2618 R_386_PLT32 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.
2619 (elf_i386_adjust_dynamic_symbol): Rework initial assertion to
2620 permit ELF_LINK_HASH_NEEDS_PLT non dynamic symbols. Create a

2633 entries and the PLT if we saw a dynamic object.
2634 * elf32-sparc.c (elf_sparc_howto_table): Fix R_SPARC_PC22 by
2635 setting rightshift to 10. Fix R_SPARC_WPLT20 by setting
2636 rightshift to 2, size to 2, bitsize to 30, and dst_mask to
2637 0x3fffffff.
2638 (elf32_sparc_create_dynamic_sections): Don't set the size of the
2639 .plt section. Call elf32_sparc_create_got_section rather than
2640 creating the .got section.

2642 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
2643 Only create the .rela.got section, and only make space for a
2644 reloc, for a global symbol or when generating a shared object.
2645 Set the alignment of the .rela.got section to 2. For a
2646 R_SPARC_WPLT30 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.
2647 (elf32_sparc_adjust_dynamic_symbol): Rework initial assertion to
2648 permit ELF_LINK_HASH_NEDS_PLT non dynamic symbols. Create a
2649 procedure linkage table for such symbols. But, if no dynamic
2650 objects were seen, never create a PLT entry. Initialize the size
2651 of the .plt section.
2652 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
2653 seen, skip most of this function, and force the size of the
2654 .rela.got section to zero. Strip empty reloc sections, and strip
2655 an empty .plt section.
2656 (elf32_sparc_relocate_section): For a GOT reloc against a global
2657 symbol when no dynamic object was seen, initialize the contents of
2658 the .got section. For a GOT reloc against a local symbol, only
2659 create a R_SPARC_RELATIVE reloc when generating a shared object.
2660 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
2661 create a PLT entry as a R_SPARC_WDISP30 reloc.
2662 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
2663 dynamic entries and the PLT if we saw a dynamic object.

6307 bss size. Fixes some problems with demand paged executables,
6308 still having problems with pure executables and shared executables.
6309
6310Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6311
6312 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6313 bfd_zalloc for rawptr, because later on we may call free, not
6314 bfd_release, on it.
6315
6316 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6317 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6318 * cisco-core.c: New file.
6319 * Makefile.in: Change accordingly.
6320 * configure.in: Recognize cisco_core_vec.
6321 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6322 * targets.c: Add cisco_core_vec.
6323 * bfd-in2.h: Rebuilt.
6324
6325Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6326
6327 * som.h (som_copyable_section_data_struct): New structure
6328 containing all the private section information which needs
6329 to be copied from input section to output section during
6330 objcopy or strip.
6331 (som_section_data_struct): Remove several fields now in
6332 som_copyable_section_data_struct. Make the space and
6333 subspace dictionaries be pointers (to save space when
6334 only reading objects).
6335
6336 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6337 some references changed. Allocate a copyable data stucture if
6338 none exists. Store info into the copyable data structure.
6339 (bfd_som_set_subsection_attributes): Likewise.
6340 (som_is_space, som_is_subspace, som_is_container): New functions.
6341 Use these instead of directly accessing private data.
6342 (som_prep_headers): Allocate space and subspace headers here.
6343 Fill in some fields in the space/subspace headers from the
6344 copyable data.
6345 (som_bfd_copy_private_section_data): Only copy the stuff
6346 that we really need to make objcopy and strip work. Allocate
6347 the copy_data structure for the output bfd before copying.
6348
6349 * som.h (struct som_exec_data): New structure to hold exec
6350 info that must be preserved when running objcopy/strip.
6351 (struct somdata): Add new "exec_data" field and accessor
6352 macro. Add some comments on how the various fields are used.
6353 (som_section_data_struct): Make is_space and is_subspace bitfields.
6354 Delete unused subspace_index. All references now use the
6355 target_index field within the section structure itself.
6356
6357 * som.c (make_unique_section): Delete unused declaration.
6358 (som_bfd_copy_private_bfd_data): New function.
6359 (som_object_setup): Allocate space for and save exec information
6360 that needs to be copied during objcopy/strip.
6361 (som_mkobject): Do not allocate space for a file header here.
6362 It is not used when only reading SOM objects.
6363 (som_prep_headers): Allocate space for and attach a file header
6364 to the output bfd. For executables, use the saved system_id
6365 value rather than trying to guess the right value. Do not abort
6366 wwhen setting file_hdr->entry* for executables.
6367 (som_begin_writing): For executables, set the exec_entry and
6368 exec_flags fields.
6369 (som_copy_private_backend_section_data): Always return a value.
6370
6371 * libhppa.h (PA_PAGESIZE): Define.
6372
6373 * som.c (SOM_ALIGN): Define.
6374 (som_begin_writing): If writing an executable, initialize all
6375 fields in the exec header to zero. Update fields in the exec
6376 header as sizes of loadable subspaces are computed. Carefully
6377 preserve alignments when building executables. Actually write the
6378 exec after all the fields are filled in.
6379
6380 * Better long-filename handling. Reads SOM ABI compliant extended
6381 names, but doesn't quite write compliant extended names yet.
6382 * som.c (som_slurp_extended_name_table): Delete function. The
6383 generic code will handle things correctly.
6384 (som_slurp_armap): Seek to the beginning of the next member.
6385 (normalize): New function.
6386 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6387 name table into account when computing the file offsets in the
6388 SOM dictionary. Make sure to align to an even boundary.
6389 (som_write_armap): Initialize the checksum to zero.
6390 (ar_maxchars): Fix. Opps.
6391
6392Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6393
6394 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6395 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6396
6397Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6398
6399 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6400 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6401 * bfd-in2.h: Regenerated.
6402
6403 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6404 this was also named trad_unix_bfd_copy_private_bfd_data.
6405
6406Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6407
6408 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6409 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6410 returns NULL, it is not an error. It's possible that some of
6411 these checks are not necessary (because the size can never be
6412 zero), but putting in the checks is the conservative thing to do
6413 in light of the fact that some of these malloc calls replaced
6414 unchecked alloca calls, in which a zero argument would work fine.
6415
6416Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6417
6418 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6419 duplicate definition.
6420 (osf_core_bfd_is_local_label): Define.
6421
6422 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6423 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6424 failure indication, it merely means there are no relocs.
6425
6426 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6427 after NAME, since SunOS /bin/cc can't handle it.
6428
6429Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6430
6431 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6432 From sukes@glue.umd.edu (Tasuki Hirata).
6433
6434Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6435
6436 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6437 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6438 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6439
6440Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6441
6442 * som.c (som_prep_for_fixups): Detect section symbols based
6443 on either the lack of private data or the symbol flags. Do not
6444 munge section symbol names anymore -- they no longer confuse GDB.
6445 (som_begin_writing): Leave space for an exec header if writing
6446 an executable.
6447 (som_slurp_symbol_table): Recognize both forms of section symbol
6448 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6449 section symbols to be the name of the section they represent.
6450 Debugging symbols begin with "L$0\001", not just "L$".
6451
6452Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6453
6454 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6455
6456 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6457 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6458 and bfd_is_local_label.
6459
6460 * targets.c: Add new entries to the bfd_target structure.
6461
6462 * bfd.c (bfd_copy_private_bfd_data): New definition.
6463
6464 * section.c (bfd_copy_private_section_data): New definition.
6465
6466 * syms.c (bfd_is_local_label): New definition.
6467
6468 * libbfd-in.h (bfd_generic_is_local_label): Declare.
6469
6470 * libbfd.c (bfd_generic_is_local_label): New function.
6471
6472 * *-core.c: Provide default definitions for new functions in
6473 the target vector which all point to bfd_false.
6474
6475 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6476 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6477 Default new vectors for copying private backend data to bfd_true.
6478 Default new vector for determining if a symbol is a local label
6479 to bfd_generic_is_local_label.
6480
6481 * som.c (som_bfd_copy_private_section_data): New function.
6482 (som_bfd_is_local_label): New function.
6483 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6484
6485 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6486
6487Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6488
6489 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6490
6491Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6492
6493 * Most files:
6494 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6495 Indent some of them to GNU standards.
6496
6497 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6498 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6499 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6500 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6501 Update copyright years.
6502
6503Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6504
6505 * som.c (som_prep_for_fixups): A relocation involving the section
6506 symbol for the *ABS* section is really a relocation involving
6507 no symbol.
6508 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6509 undefined symbols. Correctly distinguish between debugger symbols
6510 and section symbols.
6511
6512 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6513 for spaces and subspaces.
6514
6515 * som.c (som_bfd_count_ar_symbols): Fix typo.
6516
6517 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6518 HAS_RELOC based on the object's magic number.
6519 (make_unique_section): Delete function. BFD and its users are
6520 prepared to handle multiple sections with the same name.
6521 (setup_sections): Allocate space on the BFD's obstack to hold
6522 section names. Use bfd_make_setion_anyway rather than the
6523 obsolete make_unique_section.
6524 (som_prep_headers): Choose the correct SOM magic number based
6525 on the BFD's flags.
6526 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6527
6528Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6529
6530 * elf32-ppc.c: Renamed from elf32-powerpc.c.
6531 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
6532 * Makefile.in, configure.in: Corresponding changes.
6533
6534Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6535
6536 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
6537
6538Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6539
6540 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6541 is always located at the start of the data section to allow
6542 recovery of the dynamic info from a stripped executable.
6543 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6544 and STYP_COMMENT.
6545
6546Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6547
6548 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6549 cruft (like the #pragma alloca for AIX).
6550 In addition to that problem, the C alloca calls xmalloc, which
6551 means checking for being out of memory can't work right. The
6552 following changes remove all uses of alloca from BFD.
6553 * hosts/solaris2.h: Remove alloca cruft.
6554 * som.c: Replace alloca with a fixed size auto array.
6555 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
6556 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
6557 sunos.c: Replace alloca with malloc and appropriate error checking and
6558 freeing.
6559 * linker.c: Replace alloca with obstack_alloc.
6560 * libbfd.h: Rebuilt.
6561
6562Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6563
6564 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6565 MIPS_R_GPREL.
6566
6567Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6568
6569 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6570 Elf*_Off typedefs by their expansion, the typedefs have been
6571 removed from include/elf/internal.h.
6572 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6573 SHT_PROGBITS section.
6574
6575Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6576
6577 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
6578
6579Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6580
6581 * configure.host: Recognize i[34]86-sequent-*.
6582
6583 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6584 return from bfd_seek indicates an error.
6585 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6586 TRAD_CORE_STACK_OFFSET.
6587 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6588 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6589
6590Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6591
6592 * som.[ch]: Do not include libhppa.h in som.c, instead include
6593 it in som.h.
6594
6595 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6596 include it in elf32-hppa.h.
6597
6598 * som.c (log2): Return -1 on error rather than aborting.
6599 (setup_sections): Bubble up an error from log2.
6600
6601 * Changes to make HP C compiler happy in both traditional
6602 and ANSI mode.
6603 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6604 field parameter.
6605 (bfd_som_set_section_attributes): Use unsigned int rather than
6606 unsigned char to avoid GNU-C extensions.
6607 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6608 or failure rather than aborting on failure.
6609
6610 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6611 som.c changes.
6612 (bfd_som_attach_aux_hdr): Add prototype.
6613 (hppa_som-gen_reloc_type): Likewise.
6614
6615 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6616 (hppa_look_for_stubs_in_section): Do not return false on failure
6617 until rest of code is ready to handle it. Abort for now.
6618
6619Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6620
6621 * bfd-in2.h: Rebuilt.
6622
6623Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
6624
6625 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
6626 * Makefile.in: delete an extra blank.
6627 * configure.in : Add i396os9k_vec.
6628
6629Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
6630
6631 * config.bfd : Add i386-os9k.
6632 * config/i386-os9k.mt : Newly add os9k target makefile.
6633
6634 * i386os9k.c : new file to handle os9k format bfd.
6635 * Makefile.in : Handle new file i386os9k.c
6636 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
6637 * cache.c : Initialize cache_sentinel to 0.
6638
6639Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6640
6641 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
6642 action in case where caller specified no argument relocation.
6643 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6644 right in the original relocation and the stub's relocation.
6645
6646 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
6647 unused symbols argument.
6648
6649 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
6650 than asymbol * for original target symbol. All callers changed.
6651 Set reloc->sym_ptr_ptr appropriately.
6652 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6653 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6654 argument. Use the output symbols when canonicalizing the relocs,
6655 creating them if necessary.
6656
6657 * linker.c (_bfd_generic_link_output_symbols): Do not
6658 rebuild/clobber the output symbols if they already exist.
6659
6660Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6661
6662 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

6664 * bfd-in2.h: Rebuilt.
6665
6666 * srec.c (hex_value): Always set to a size of 256 bytes.
6667 (srec_init): Cosmetic changes.

6670
6671 * elf32-hppa.c: Second half of major cleanup. More comments,
6672 PARAMize and staticize rest of functions. Delete unused
6673 functions. Delete unused/unnecessary arguments to some functions.
6674 Group static vars together. Abort for bad errors until we have
6675 error code propogation working. Work on spacing and indention.
6676 Add FIXMEs for unresolved problems. Use enums rather than
6677 #defines for lots of things. Merge two functions which build
6678 linker stubs into a single function (so they can easily share a
6679 ton of common code).
6680
6681Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
6682
6683 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
6684 avoid depending upon right shifts of signed numbers, and to
6685 correct handling of src_mask with lower bits zero.

6688 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
6689 * elf32-i386.c: Likewise.
6690 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old
6691 #if 0 code.
6692 (elf_write_phdrs): Make i unsigned.
6693 (map_program_segments): Make i and n_left unsigned.
6694 (assign_file_positions_except_relocs): Make i unsigned.

7435
7436 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros

7653 return value.
7654 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
7655 out dynamic symbols or relocs against reloc symbols, since they
7656 are already in the .text section and we wouldn't know where to
7657 write them anyhow.
