3457 allocating space for relocations. Handle them in link_order loop.
3458 (_bfd_generic_reloc_link_order): New function.
3459 (_bfd_default_link_order): If a reloc_link_order is seen here,
3461 (_bfd_count_link_order_relocs): New function.
3462 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3463 argument from declaration.
3464 (_bfd_generic_reloc_link_order): Declare.
3465 (_bfd_count_link_order_relocs): Declare.
3466 * libbfd.h: Rebuilt.
3467 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3468 call to _bfd_generic_link_add_one_symbol.
3469 (NAME(aout,final_link)): Account for link_order relocs when
3470 allocating space for relocations. Handle them after handling all
3472 (aout_link_reloc_link_order): New function.
3473 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
3474 call to _bfd_generic_link_add_one_symbol.
3475 (ecoff_bfd_final_link): Account for link_order relocs when
3476 allocating space for relocations. Handle them in link_order loop.
3477 (ecoff_link_write_external): Set the storage class of a defined
3478 linker created symbol based on the section it is in. Correct
3479 bfd_link_hash_weak case to use .sc rather than .st.
3480 (ecoff_reloc_link_order): New function.
3481 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3483 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
3485 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
3488 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3489 bfd_zmalloc. Free a pointer, not a union.
3490 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3492 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3494 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3496 * som.c (bfd_section_from_som_symbol): Only to do the value
3497 comparison for function symbols within executables.
3499 * som.c (bfd_section_from_som_symbol): Renamed from
3500 som_section_from_subspace_index. Pass in a native SOM symbol.
3501 For executables, iterate through the sections to find out
3502 which contains the symbol's address rather than using the
3503 symbol_info field. (symbol_info has a different meaning for
3504 dynamicly linked executables.)
3506 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3509 * som.c (som_begin_writing): Fix braino (one call to align
3510 space/subspace data was done unconditionally rather than
3511 just for executables.)
3513 * som.c (som_begin_writing): Align text in all executables to
3514 make HPUX kernel happy. Fixes strip/objcopy for shared
3517 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3519 * som.c (som_begin_writing): Account for alignment needs of
3520 subspaces too when writing executables. Never request a negative
3521 bss size. Fixes some problems with demand paged executables,
3522 still having problems with pure executables and shared executables.
3524 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3526 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3527 bfd_zalloc for rawptr, because later on we may call free, not
3530 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3531 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3532 * cisco-core.c: New file.
3533 * Makefile.in: Change accordingly.
3534 * configure.in: Recognize cisco_core_vec.
3535 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3536 * targets.c: Add cisco_core_vec.
3537 * bfd-in2.h: Rebuilt.
3539 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3541 * som.h (som_copyable_section_data_struct): New structure
3542 containing all the private section information which needs
3543 to be copied from input section to output section during
3545 (som_section_data_struct): Remove several fields now in
3546 som_copyable_section_data_struct. Make the space and
3547 subspace dictionaries be pointers (to save space when
3548 only reading objects).
3550 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3551 some references changed. Allocate a copyable data stucture if
3552 none exists. Store info into the copyable data structure.
3553 (bfd_som_set_subsection_attributes): Likewise.
3554 (som_is_space, som_is_subspace, som_is_container): New functions.
3555 Use these instead of directly accessing private data.
3556 (som_prep_headers): Allocate space and subspace headers here.
3557 Fill in some fields in the space/subspace headers from the
3559 (som_bfd_copy_private_section_data): Only copy the stuff
3560 that we really need to make objcopy and strip work. Allocate
3561 the copy_data structure for the output bfd before copying.
3563 * som.h (struct som_exec_data): New structure to hold exec
3564 info that must be preserved when running objcopy/strip.
3565 (struct somdata): Add new "exec_data" field and accessor
3566 macro. Add some comments on how the various fields are used.
3567 (som_section_data_struct): Make is_space and is_subspace bitfields.
3568 Delete unused subspace_index. All references now use the
3569 target_index field within the section structure itself.
3571 * som.c (make_unique_section): Delete unused declaration.
3572 (som_bfd_copy_private_bfd_data): New function.
3573 (som_object_setup): Allocate space for and save exec information
3574 that needs to be copied during objcopy/strip.
3575 (som_mkobject): Do not allocate space for a file header here.
3576 It is not used when only reading SOM objects.
3577 (som_prep_headers): Allocate space for and attach a file header
3578 to the output bfd. For executables, use the saved system_id
3579 value rather than trying to guess the right value. Do not abort
3580 wwhen setting file_hdr->entry* for executables.
3581 (som_begin_writing): For executables, set the exec_entry and
3583 (som_copy_private_backend_section_data): Always return a value.
3585 * libhppa.h (PA_PAGESIZE): Define.
3587 * som.c (SOM_ALIGN): Define.
3588 (som_begin_writing): If writing an executable, initialize all
3589 fields in the exec header to zero. Update fields in the exec
3590 header as sizes of loadable subspaces are computed. Carefully
3591 preserve alignments when building executables. Actually write the
3592 exec after all the fields are filled in.
3594 * Better long-filename handling. Reads SOM ABI compliant extended
3595 names, but doesn't quite write compliant extended names yet.
3596 * som.c (som_slurp_extended_name_table): Delete function. The
3597 generic code will handle things correctly.
3598 (som_slurp_armap): Seek to the beginning of the next member.
3599 (normalize): New function.
3600 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3601 name table into account when computing the file offsets in the
3602 SOM dictionary. Make sure to align to an even boundary.
3603 (som_write_armap): Initialize the checksum to zero.
3604 (ar_maxchars): Fix. Opps.
3606 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3608 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3609 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3611 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3613 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3614 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3615 * bfd-in2.h: Regenerated.
3617 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3618 this was also named trad_unix_bfd_copy_private_bfd_data.
3620 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3622 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3623 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3624 returns NULL, it is not an error. It's possible that some of
3625 these checks are not necessary (because the size can never be
3626 zero), but putting in the checks is the conservative thing to do
3627 in light of the fact that some of these malloc calls replaced
3628 unchecked alloca calls, in which a zero argument would work fine.
3630 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3632 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3633 duplicate definition.
3634 (osf_core_bfd_is_local_label): Define.
3636 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3637 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3638 failure indication, it merely means there are no relocs.
3640 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3641 after NAME, since SunOS /bin/cc can't handle it.
3643 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3645 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3646 From sukes@glue.umd.edu (Tasuki Hirata).
3648 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3650 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3651 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3652 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3654 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3656 * som.c (som_prep_for_fixups): Detect section symbols based
3657 on either the lack of private data or the symbol flags. Do not
3658 munge section symbol names anymore -- they no longer confuse GDB.
3659 (som_begin_writing): Leave space for an exec header if writing
3661 (som_slurp_symbol_table): Recognize both forms of section symbol
3662 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3663 section symbols to be the name of the section they represent.
3664 Debugging symbols begin with "L$0\001", not just "L$".
3666 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3668 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3670 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3671 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3672 and bfd_is_local_label.
3674 * targets.c: Add new entries to the bfd_target structure.
3676 * bfd.c (bfd_copy_private_bfd_data): New definition.
3678 * section.c (bfd_copy_private_section_data): New definition.
3680 * syms.c (bfd_is_local_label): New definition.
3682 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3684 * libbfd.c (bfd_generic_is_local_label): New function.
3686 * *-core.c: Provide default definitions for new functions in
3687 the target vector which all point to bfd_false.
3689 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3690 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3691 Default new vectors for copying private backend data to bfd_true.
3692 Default new vector for determining if a symbol is a local label
3693 to bfd_generic_is_local_label.
3695 * som.c (som_bfd_copy_private_section_data): New function.
3696 (som_bfd_is_local_label): New function.
3697 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3699 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3701 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3703 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3705 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3708 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3709 Indent some of them to GNU standards.
3711 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3712 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3713 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3714 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3715 Update copyright years.
3717 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3719 * som.c (som_prep_for_fixups): A relocation involving the section
3720 symbol for the *ABS* section is really a relocation involving
3722 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3723 undefined symbols. Correctly distinguish between debugger symbols
3724 and section symbols.
3726 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3727 for spaces and subspaces.
3729 * som.c (som_bfd_count_ar_symbols): Fix typo.
3731 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3732 HAS_RELOC based on the object's magic number.
3733 (make_unique_section): Delete function. BFD and its users are
3734 prepared to handle multiple sections with the same name.
3735 (setup_sections): Allocate space on the BFD's obstack to hold
3736 section names. Use bfd_make_setion_anyway rather than the
3737 obsolete make_unique_section.
3738 (som_prep_headers): Choose the correct SOM magic number based
3740 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3742 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3744 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3745 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3746 * Makefile.in, configure.in: Corresponding changes.
3748 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3750 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3752 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3754 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3755 is always located at the start of the data section to allow
3756 recovery of the dynamic info from a stripped executable.
3757 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3760 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3762 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3763 cruft (like the #pragma alloca for AIX).
3764 In addition to that problem, the C alloca calls xmalloc, which
3765 means checking for being out of memory can't work right. The
3766 following changes remove all uses of alloca from BFD.
3767 * hosts/solaris2.h: Remove alloca cruft.
3768 * som.c: Replace alloca with a fixed size auto array.
3769 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3770 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3771 sunos.c: Replace alloca with malloc and appropriate error checking and
3773 * linker.c: Replace alloca with obstack_alloc.
3774 * libbfd.h: Rebuilt.
3776 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3778 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3781 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3783 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3784 Elf*_Off typedefs by their expansion, the typedefs have been
3785 removed from include/elf/internal.h.
3786 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3787 SHT_PROGBITS section.
3789 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3791 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3797 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3798 return from bfd_seek indicates an error.
3799 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3800 TRAD_CORE_STACK_OFFSET.
3801 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3802 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3804 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3806 * som.[ch]: Do not include libhppa.h in som.c, instead include
3809 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3810 include it in elf32-hppa.h.
3812 * som.c (log2): Return -1 on error rather than aborting.
3813 (setup_sections): Bubble up an error from log2.
3815 * Changes to make HP C compiler happy in both traditional
3817 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3819 (bfd_som_set_section_attributes): Use unsigned int rather than
3820 unsigned char to avoid GNU-C extensions.
3821 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3822 or failure rather than aborting on failure.
3824 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3826 (bfd_som_attach_aux_hdr): Add prototype.
3827 (hppa_som-gen_reloc_type): Likewise.
3829 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3830 (hppa_look_for_stubs_in_section): Do not return false on failure
3831 until rest of code is ready to handle it. Abort for now.

3835 * bfd-in2.h: Rebuilt.
3837 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

3846 * config/i386-os9k.mt : Newly add os9k target makefile.
3848 * i386os9k.c : new file to handle os9k format bfd.
3849 * Makefile.in : Handle new file i386os9k.c
3850 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
3851 * cache.c : Initialize cache_sentinel to 0.

3855 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
3856 action in case where caller specified no argument relocation.
3857 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3858 right in the original relocation and the stub's relocation.
3860 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3861 unused symbols argument.
3863 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3864 than asymbol * for original target symbol. All callers changed.
3865 Set reloc->sym_ptr_ptr appropriately.
3866 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3867 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3868 argument. Use the output symbols when canonicalizing the relocs,
3869 creating them if necessary.
3871 * linker.c (_bfd_generic_link_output_symbols): Do not
3872 rebuild/clobber the output symbols if they already exist.
3874 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3876 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3877 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3878 * bfd-in2.h: Rebuilt.
3880 * srec.c (hex_value): Always set to a size of 256 bytes.
3881 (srec_init): Cosmetic changes.
3883 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3885 * elf32-hppa.c: Second half of major cleanup. More comments,
3886 PARAMize and staticize rest of functions. Delete unused
3887 functions. Delete unused/unnecessary arguments to some functions.
3888 Group static vars together. Abort for bad errors until we have
3889 error code propogation working. Work on spacing and indention.
3890 Add FIXMEs for unresolved problems. Use enums rather than
3891 #defines for lots of things. Merge two functions which build
3892 linker stubs into a single function (so they can easily share a
3893 ton of common code).
3895 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3897 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3898 avoid depending upon right shifts of signed numbers, and to
3899 correct handling of src_mask with lower bits zero.
3901 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3902 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
3903 * elf32-i386.c: Likewise.
3904 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old

6107 terms of MY, because that causes a recusive invocation of CAT when
6108 expanded within JUMP_TABLE, and ANSI compilers don't expand
6110 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
6111 MY_reloc_howto_type_lookup, and don't define in terms of MY.
6112 (MY_canonicalize_reloc): Don't define in terms of MY.
6113 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
6114 than listing functions.
