3462 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3463 bfd_zalloc for rawptr, because later on we may call free, not
3466 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3467 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3468 * cisco-core.c: New file.
3469 * Makefile.in: Change accordingly.
3470 * configure.in: Recognize cisco_core_vec.
3471 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3472 * targets.c: Add cisco_core_vec.
3473 * bfd-in2.h: Rebuilt.
3475 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3477 * som.h (som_copyable_section_data_struct): New structure
3478 containing all the private section information which needs
3479 to be copied from input section to output section during
3481 (som_section_data_struct): Remove several fields now in
3482 som_copyable_section_data_struct. Make the space and
3483 subspace dictionaries be pointers (to save space when
3484 only reading objects).
3486 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3487 some references changed. Allocate a copyable data stucture if
3488 none exists. Store info into the copyable data structure.
3489 (bfd_som_set_subsection_attributes): Likewise.
3490 (som_is_space, som_is_subspace, som_is_container): New functions.
3491 Use these instead of directly accessing private data.
3492 (som_prep_headers): Allocate space and subspace headers here.
3493 Fill in some fields in the space/subspace headers from the
3495 (som_bfd_copy_private_section_data): Only copy the stuff
3496 that we really need to make objcopy and strip work. Allocate
3497 the copy_data structure for the output bfd before copying.
3499 * som.h (struct som_exec_data): New structure to hold exec
3500 info that must be preserved when running objcopy/strip.
3501 (struct somdata): Add new "exec_data" field and accessor
3502 macro. Add some comments on how the various fields are used.
3503 (som_section_data_struct): Make is_space and is_subspace bitfields.
3504 Delete unused subspace_index. All references now use the
3505 target_index field within the section structure itself.
3507 * som.c (make_unique_section): Delete unused declaration.
3508 (som_bfd_copy_private_bfd_data): New function.
3509 (som_object_setup): Allocate space for and save exec information
3510 that needs to be copied during objcopy/strip.
3511 (som_mkobject): Do not allocate space for a file header here.
3512 It is not used when only reading SOM objects.
3513 (som_prep_headers): Allocate space for and attach a file header
3514 to the output bfd. For executables, use the saved system_id
3515 value rather than trying to guess the right value. Do not abort
3516 wwhen setting file_hdr->entry* for executables.
3517 (som_begin_writing): For executables, set the exec_entry and
3519 (som_copy_private_backend_section_data): Always return a value.
3521 * libhppa.h (PA_PAGESIZE): Define.
3523 * som.c (SOM_ALIGN): Define.
3524 (som_begin_writing): If writing an executable, initialize all
3525 fields in the exec header to zero. Update fields in the exec
3526 header as sizes of loadable subspaces are computed. Carefully
3527 preserve alignments when building executables. Actually write the
3528 exec after all the fields are filled in.
3530 * Better long-filename handling. Reads SOM ABI compliant extended
3531 names, but doesn't quite write compliant extended names yet.
3532 * som.c (som_slurp_extended_name_table): Delete function. The
3533 generic code will handle things correctly.
3534 (som_slurp_armap): Seek to the beginning of the next member.
3535 (normalize): New function.
3536 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3537 name table into account when computing the file offsets in the
3538 SOM dictionary. Make sure to align to an even boundary.
3539 (som_write_armap): Initialize the checksum to zero.
3540 (ar_maxchars): Fix. Opps.
3542 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3544 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3545 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3547 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3549 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3550 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3551 * bfd-in2.h: Regenerated.
3553 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3554 this was also named trad_unix_bfd_copy_private_bfd_data.
3556 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3558 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3559 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3560 returns NULL, it is not an error. It's possible that some of
3561 these checks are not necessary (because the size can never be
3562 zero), but putting in the checks is the conservative thing to do
3563 in light of the fact that some of these malloc calls replaced
3564 unchecked alloca calls, in which a zero argument would work fine.
3566 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3568 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3569 duplicate definition.
3570 (osf_core_bfd_is_local_label): Define.
3572 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3573 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3574 failure indication, it merely means there are no relocs.
3576 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3577 after NAME, since SunOS /bin/cc can't handle it.
3579 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3581 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3582 From sukes@glue.umd.edu (Tasuki Hirata).
3584 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3586 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3587 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3588 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3590 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3592 * som.c (som_prep_for_fixups): Detect section symbols based
3593 on either the lack of private data or the symbol flags. Do not
3594 munge section symbol names anymore -- they no longer confuse GDB.
3595 (som_begin_writing): Leave space for an exec header if writing
3597 (som_slurp_symbol_table): Recognize both forms of section symbol
3598 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3599 section symbols to be the name of the section they represent.
3600 Debugging symbols begin with "L$0\001", not just "L$".
3602 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3604 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3606 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3607 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3608 and bfd_is_local_label.
3610 * targets.c: Add new entries to the bfd_target structure.
3612 * bfd.c (bfd_copy_private_bfd_data): New definition.
3614 * section.c (bfd_copy_private_section_data): New definition.

3618 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3620 * libbfd.c (bfd_generic_is_local_label): New function.
3622 * *-core.c: Provide default definitions for new functions in
3623 the target vector which all point to bfd_false.
3625 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3626 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3627 Default new vectors for copying private backend data to bfd_true.
3628 Default new vector for determining if a symbol is a local label
3629 to bfd_generic_is_local_label.
3631 * som.c (som_bfd_copy_private_section_data): New function.
3632 (som_bfd_is_local_label): New function.
3633 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3635 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3637 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3639 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3641 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3644 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3645 Indent some of them to GNU standards.
3647 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3648 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3649 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3650 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3651 Update copyright years.
3653 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3655 * som.c (som_prep_for_fixups): A relocation involving the section
3656 symbol for the *ABS* section is really a relocation involving
3658 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3659 undefined symbols. Correctly distinguish between debugger symbols
3660 and section symbols.
3662 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3663 for spaces and subspaces.
3665 * som.c (som_bfd_count_ar_symbols): Fix typo.
3667 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3668 HAS_RELOC based on the object's magic number.
3669 (make_unique_section): Delete function. BFD and its users are
3670 prepared to handle multiple sections with the same name.
3671 (setup_sections): Allocate space on the BFD's obstack to hold
3672 section names. Use bfd_make_setion_anyway rather than the
3673 obsolete make_unique_section.
3674 (som_prep_headers): Choose the correct SOM magic number based
3676 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3678 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3680 * elf32-ppc.c: Renamed from elf32-powerpc.c.

3690 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3691 is always located at the start of the data section to allow
3692 recovery of the dynamic info from a stripped executable.

3696 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3698 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3699 cruft (like the #pragma alloca for AIX).
3700 In addition to that problem, the C alloca calls xmalloc, which
3701 means checking for being out of memory can't work right. The
3702 following changes remove all uses of alloca from BFD.
3703 * hosts/solaris2.h: Remove alloca cruft.
3704 * som.c: Replace alloca with a fixed size auto array.
3705 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3706 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3707 sunos.c: Replace alloca with malloc and appropriate error checking and
3709 * linker.c: Replace alloca with obstack_alloc.
3710 * libbfd.h: Rebuilt.
3712 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3714 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3717 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3719 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3720 Elf*_Off typedefs by their expansion, the typedefs have been
3721 removed from include/elf/internal.h.
3722 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3723 SHT_PROGBITS section.
3725 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3727 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3733 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3734 return from bfd_seek indicates an error.
3735 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3736 TRAD_CORE_STACK_OFFSET.
3737 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3738 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3740 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3742 * som.[ch]: Do not include libhppa.h in som.c, instead include
3745 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3746 include it in elf32-hppa.h.
3748 * som.c (log2): Return -1 on error rather than aborting.
3749 (setup_sections): Bubble up an error from log2.
3751 * Changes to make HP C compiler happy in both traditional
3753 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3755 (bfd_som_set_section_attributes): Use unsigned int rather than
3756 unsigned char to avoid GNU-C extensions.
3757 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3758 or failure rather than aborting on failure.
3760 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3762 (bfd_som_attach_aux_hdr): Add prototype.
3763 (hppa_som-gen_reloc_type): Likewise.
3765 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3766 (hppa_look_for_stubs_in_section): Do not return false on failure
3767 until rest of code is ready to handle it. Abort for now.

3792 action in case where caller specified no argument relocation.
3793 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3794 right in the original relocation and the stub's relocation.
3796 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3797 unused symbols argument.
3799 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

3801 Set reloc->sym_ptr_ptr appropriately.
3802 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3803 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3804 argument. Use the output symbols when canonicalizing the relocs,
3805 creating them if necessary.
3807 * linker.c (_bfd_generic_link_output_symbols): Do not
3808 rebuild/clobber the output symbols if they already exist.
3810 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3812 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

3814 * bfd-in2.h: Rebuilt.
3816 * srec.c (hex_value): Always set to a size of 256 bytes.
3817 (srec_init): Cosmetic changes.
3819 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3822 PARAMize and staticize rest of functions. Delete unused
3823 functions. Delete unused/unnecessary arguments to some functions.
3824 Group static vars together. Abort for bad errors until we have
3825 error code propogation working. Work on spacing and indention.
3826 Add FIXMEs for unresolved problems. Use enums rather than
3827 #defines for lots of things. Merge two functions which build
3828 linker stubs into a single function (so they can easily share a
3829 ton of common code).
3831 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3833 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3834 avoid depending upon right shifts of signed numbers, and to
3835 correct handling of src_mask with lower bits zero.
3837 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3838 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3865 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3866 (elf_hppa_tc_make_sections): Likewise.
3867 (elf_hppa_final_processing): Add extern decl.
3869 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3870 comments. PARAMize some static functions. Delete unused functions.
3871 Delete unused/unnecessary arguments to many functions. Group
3872 static vars together. Collapse common case statements together
3873 in many places. Use default case when possible instead of listing
3874 each case separately. Abort for bad errors until we get error
3875 code propogation working. Work on spacing and indention problems.
3876 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3877 COMPLEX relocation support (it's never used anyway).
3878 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3879 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3880 (elf_hppa_tc_make_sections): Likewise.
3882 * format.c (bfd_check_format_matches): Initialize matching_vector

3893 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3895 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4619 bfd_som_set_subsection_attributes): Change parameters from char
4620 to int. Following a prototype with an old-style function definition

4727 use get_value to get the symbol value and check for undefined
4729 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4730 undefined, look it up in the linker hash table.
4732 * aoutx.h (translate_symbol_table): The string index 0 has a

4757 The sparc (and possibly other?) NLM format requires a different
4758 way to write exports, so add a write_export field to the backend
4759 data (and set it to NULL for everything but the sparc).
