3458 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3459 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3460 instead of bitsize to add_to_set call back.
3461 (_bfd_generic_final_link): Account for link_order relocs when
3462 allocating space for relocations. Handle them in link_order loop.
3463 (_bfd_generic_reloc_link_order): New function.
3464 (_bfd_default_link_order): If a reloc_link_order is seen here,
3466 (_bfd_count_link_order_relocs): New function.
3467 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3468 argument from declaration.
3469 (_bfd_generic_reloc_link_order): Declare.
3470 (_bfd_count_link_order_relocs): Declare.
3471 * libbfd.h: Rebuilt.
3472 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3473 call to _bfd_generic_link_add_one_symbol.
3474 (NAME(aout,final_link)): Account for link_order relocs when
3475 allocating space for relocations. Handle them after handling all
3477 (aout_link_reloc_link_order): New function.
3478 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
3479 call to _bfd_generic_link_add_one_symbol.
3480 (ecoff_bfd_final_link): Account for link_order relocs when
3481 allocating space for relocations. Handle them in link_order loop.
3482 (ecoff_link_write_external): Set the storage class of a defined
3483 linker created symbol based on the section it is in. Correct
3484 bfd_link_hash_weak case to use .sc rather than .st.
3485 (ecoff_reloc_link_order): New function.
3486 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3488 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
3490 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
3493 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3494 bfd_zmalloc. Free a pointer, not a union.
3495 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3497 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3499 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3501 * som.c (bfd_section_from_som_symbol): Only to do the value
3502 comparison for function symbols within executables.
3504 * som.c (bfd_section_from_som_symbol): Renamed from
3505 som_section_from_subspace_index. Pass in a native SOM symbol.
3506 For executables, iterate through the sections to find out
3507 which contains the symbol's address rather than using the
3508 symbol_info field. (symbol_info has a different meaning for
3509 dynamicly linked executables.)
3511 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3514 * som.c (som_begin_writing): Fix braino (one call to align
3515 space/subspace data was done unconditionally rather than
3516 just for executables.)
3518 * som.c (som_begin_writing): Align text in all executables to
3519 make HPUX kernel happy. Fixes strip/objcopy for shared
3522 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3524 * som.c (som_begin_writing): Account for alignment needs of
3525 subspaces too when writing executables. Never request a negative
3526 bss size. Fixes some problems with demand paged executables,
3527 still having problems with pure executables and shared executables.
3529 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3531 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3532 bfd_zalloc for rawptr, because later on we may call free, not
3535 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3536 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3537 * cisco-core.c: New file.
3538 * Makefile.in: Change accordingly.
3539 * configure.in: Recognize cisco_core_vec.
3540 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3541 * targets.c: Add cisco_core_vec.
3542 * bfd-in2.h: Rebuilt.
3544 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3546 * som.h (som_copyable_section_data_struct): New structure
3547 containing all the private section information which needs
3548 to be copied from input section to output section during
3550 (som_section_data_struct): Remove several fields now in
3551 som_copyable_section_data_struct. Make the space and
3552 subspace dictionaries be pointers (to save space when
3553 only reading objects).
3555 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3556 some references changed. Allocate a copyable data stucture if
3557 none exists. Store info into the copyable data structure.
3558 (bfd_som_set_subsection_attributes): Likewise.
3559 (som_is_space, som_is_subspace, som_is_container): New functions.
3560 Use these instead of directly accessing private data.
3561 (som_prep_headers): Allocate space and subspace headers here.
3562 Fill in some fields in the space/subspace headers from the
3564 (som_bfd_copy_private_section_data): Only copy the stuff
3565 that we really need to make objcopy and strip work. Allocate
3566 the copy_data structure for the output bfd before copying.
3568 * som.h (struct som_exec_data): New structure to hold exec
3569 info that must be preserved when running objcopy/strip.
3570 (struct somdata): Add new "exec_data" field and accessor
3571 macro. Add some comments on how the various fields are used.
3572 (som_section_data_struct): Make is_space and is_subspace bitfields.
3573 Delete unused subspace_index. All references now use the
3574 target_index field within the section structure itself.
3576 * som.c (make_unique_section): Delete unused declaration.
3577 (som_bfd_copy_private_bfd_data): New function.
3578 (som_object_setup): Allocate space for and save exec information
3579 that needs to be copied during objcopy/strip.
3580 (som_mkobject): Do not allocate space for a file header here.
3581 It is not used when only reading SOM objects.
3582 (som_prep_headers): Allocate space for and attach a file header
3583 to the output bfd. For executables, use the saved system_id
3584 value rather than trying to guess the right value. Do not abort
3585 wwhen setting file_hdr->entry* for executables.
3586 (som_begin_writing): For executables, set the exec_entry and
3588 (som_copy_private_backend_section_data): Always return a value.
3590 * libhppa.h (PA_PAGESIZE): Define.
3592 * som.c (SOM_ALIGN): Define.
3593 (som_begin_writing): If writing an executable, initialize all
3594 fields in the exec header to zero. Update fields in the exec
3595 header as sizes of loadable subspaces are computed. Carefully
3596 preserve alignments when building executables. Actually write the
3597 exec after all the fields are filled in.
3599 * Better long-filename handling. Reads SOM ABI compliant extended
3600 names, but doesn't quite write compliant extended names yet.
3601 * som.c (som_slurp_extended_name_table): Delete function. The
3602 generic code will handle things correctly.
3603 (som_slurp_armap): Seek to the beginning of the next member.
3604 (normalize): New function.
3605 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3606 name table into account when computing the file offsets in the
3607 SOM dictionary. Make sure to align to an even boundary.
3608 (som_write_armap): Initialize the checksum to zero.
3609 (ar_maxchars): Fix. Opps.
3611 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3613 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3614 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3616 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3618 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3619 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3620 * bfd-in2.h: Regenerated.
3622 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3623 this was also named trad_unix_bfd_copy_private_bfd_data.
3625 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3627 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3628 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3629 returns NULL, it is not an error. It's possible that some of
3630 these checks are not necessary (because the size can never be
3631 zero), but putting in the checks is the conservative thing to do
3632 in light of the fact that some of these malloc calls replaced
3633 unchecked alloca calls, in which a zero argument would work fine.
3635 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3637 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3638 duplicate definition.
3639 (osf_core_bfd_is_local_label): Define.
3641 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3642 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3643 failure indication, it merely means there are no relocs.
3645 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3646 after NAME, since SunOS /bin/cc can't handle it.
3648 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3650 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3651 From sukes@glue.umd.edu (Tasuki Hirata).
3653 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3655 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3656 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3657 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3659 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3661 * som.c (som_prep_for_fixups): Detect section symbols based
3662 on either the lack of private data or the symbol flags. Do not
3663 munge section symbol names anymore -- they no longer confuse GDB.
3664 (som_begin_writing): Leave space for an exec header if writing
3666 (som_slurp_symbol_table): Recognize both forms of section symbol
3667 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3668 section symbols to be the name of the section they represent.
3669 Debugging symbols begin with "L$0\001", not just "L$".
3671 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3673 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3675 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3676 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3677 and bfd_is_local_label.
3679 * targets.c: Add new entries to the bfd_target structure.
3681 * bfd.c (bfd_copy_private_bfd_data): New definition.
3683 * section.c (bfd_copy_private_section_data): New definition.
3685 * syms.c (bfd_is_local_label): New definition.
3687 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3689 * libbfd.c (bfd_generic_is_local_label): New function.
3691 * *-core.c: Provide default definitions for new functions in
3692 the target vector which all point to bfd_false.
3694 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3695 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3696 Default new vectors for copying private backend data to bfd_true.
3697 Default new vector for determining if a symbol is a local label
3698 to bfd_generic_is_local_label.
3700 * som.c (som_bfd_copy_private_section_data): New function.
3701 (som_bfd_is_local_label): New function.
3702 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3704 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3706 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3708 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3710 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3713 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3714 Indent some of them to GNU standards.
3716 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3717 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3718 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3719 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3720 Update copyright years.
3722 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3724 * som.c (som_prep_for_fixups): A relocation involving the section
3725 symbol for the *ABS* section is really a relocation involving
3727 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3728 undefined symbols. Correctly distinguish between debugger symbols
3729 and section symbols.
3731 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3732 for spaces and subspaces.
3734 * som.c (som_bfd_count_ar_symbols): Fix typo.
3736 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3737 HAS_RELOC based on the object's magic number.
3738 (make_unique_section): Delete function. BFD and its users are
3739 prepared to handle multiple sections with the same name.
3740 (setup_sections): Allocate space on the BFD's obstack to hold
3741 section names. Use bfd_make_setion_anyway rather than the
3742 obsolete make_unique_section.
3743 (som_prep_headers): Choose the correct SOM magic number based
3745 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3747 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3749 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3750 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3751 * Makefile.in, configure.in: Corresponding changes.
3753 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3755 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3757 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3759 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3760 is always located at the start of the data section to allow
3761 recovery of the dynamic info from a stripped executable.
3762 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3765 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3767 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3768 cruft (like the #pragma alloca for AIX).
3769 In addition to that problem, the C alloca calls xmalloc, which
3770 means checking for being out of memory can't work right. The
3771 following changes remove all uses of alloca from BFD.
3772 * hosts/solaris2.h: Remove alloca cruft.
3773 * som.c: Replace alloca with a fixed size auto array.
3774 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3775 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3776 sunos.c: Replace alloca with malloc and appropriate error checking and
3778 * linker.c: Replace alloca with obstack_alloc.
3779 * libbfd.h: Rebuilt.
3781 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3783 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3786 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3788 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3789 Elf*_Off typedefs by their expansion, the typedefs have been
3790 removed from include/elf/internal.h.
3791 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3792 SHT_PROGBITS section.
3794 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3796 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3800 * configure.host: Recognize i[34]86-sequent-*.
3802 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3803 return from bfd_seek indicates an error.
3804 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3805 TRAD_CORE_STACK_OFFSET.
3806 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3807 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3809 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3811 * som.[ch]: Do not include libhppa.h in som.c, instead include
3814 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3815 include it in elf32-hppa.h.
3817 * som.c (log2): Return -1 on error rather than aborting.
3818 (setup_sections): Bubble up an error from log2.
3820 * Changes to make HP C compiler happy in both traditional
3822 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3824 (bfd_som_set_section_attributes): Use unsigned int rather than
3825 unsigned char to avoid GNU-C extensions.
3826 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3827 or failure rather than aborting on failure.
3829 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3831 (bfd_som_attach_aux_hdr): Add prototype.
3832 (hppa_som-gen_reloc_type): Likewise.
3834 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3835 (hppa_look_for_stubs_in_section): Do not return false on failure
3836 until rest of code is ready to handle it. Abort for now.
3838 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3840 * bfd-in2.h: Rebuilt.
3842 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
3844 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

3848 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
3850 * config.bfd : Add i386-os9k.
3851 * config/i386-os9k.mt : Newly add os9k target makefile.
3853 * i386os9k.c : new file to handle os9k format bfd.
3854 * Makefile.in : Handle new file i386os9k.c
3855 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
3856 * cache.c : Initialize cache_sentinel to 0.
3858 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3860 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
3861 action in case where caller specified no argument relocation.
3862 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3863 right in the original relocation and the stub's relocation.
3865 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3866 unused symbols argument.
3868 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3869 than asymbol * for original target symbol. All callers changed.
3870 Set reloc->sym_ptr_ptr appropriately.
3871 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3872 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3873 argument. Use the output symbols when canonicalizing the relocs,
3874 creating them if necessary.
3876 * linker.c (_bfd_generic_link_output_symbols): Do not
3877 rebuild/clobber the output symbols if they already exist.
3879 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3881 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3882 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3883 * bfd-in2.h: Rebuilt.
3885 * srec.c (hex_value): Always set to a size of 256 bytes.
3886 (srec_init): Cosmetic changes.
3888 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3890 * elf32-hppa.c: Second half of major cleanup. More comments,
3891 PARAMize and staticize rest of functions. Delete unused
3892 functions. Delete unused/unnecessary arguments to some functions.
3893 Group static vars together. Abort for bad errors until we have
3894 error code propogation working. Work on spacing and indention.
3895 Add FIXMEs for unresolved problems. Use enums rather than
3896 #defines for lots of things. Merge two functions which build
3897 linker stubs into a single function (so they can easily share a
3898 ton of common code).
3900 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3902 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3903 avoid depending upon right shifts of signed numbers, and to
3904 correct handling of src_mask with lower bits zero.
3906 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3907 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
3908 * elf32-i386.c: Likewise.

6107 MY_reloc_howto_type_lookup.
6108 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
6109 (MY(vec)): Use JUMP_TABLE rather than listing functions.
6110 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
6111 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
6112 terms of MY, because that causes a recusive invocation of CAT when
6113 expanded within JUMP_TABLE, and ANSI compilers don't expand
6115 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
6116 MY_reloc_howto_type_lookup, and don't define in terms of MY.
6117 (MY_canonicalize_reloc): Don't define in terms of MY.
6118 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
6119 than listing functions.
