3495 in asymbol udata field.
3497 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3499 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3500 reloc, used in embedded PIC code.
3501 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3509 add_symbls entry point.
3511 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3512 counting relocs. Set SEC_RELOC flag for any section which has

3518 generic_link_add_symbols.
3519 (_bfd_generic_link_add_symbols_collect): New function, like
3520 _bfd_generic_link_add_symbols but also collect constructors and
3521 destructors by name as collect2 does.
3522 (generic_link_add_symbols): New function, like old
3523 _bfd_generic_link_add_symbols but with collect argument.
3524 (generic_link_add_object_symbols): Take collect argument.

3536 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3537 for first character in an extended name.
3538 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3539 "//" as the name of the special archive member holding the
3540 extended name table.
3542 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3544 Support for link_order types which generate relocs in order to
3545 support -Ur in the linker.
3546 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3547 from call to _bfd_generic_link_add_one_symbol.
3548 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3549 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3550 instead of bitsize to add_to_set call back.
3551 (_bfd_generic_final_link): Account for link_order relocs when
3552 allocating space for relocations. Handle them in link_order loop.
3553 (_bfd_generic_reloc_link_order): New function.
3554 (_bfd_default_link_order): If a reloc_link_order is seen here,
3556 (_bfd_count_link_order_relocs): New function.
3557 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3558 argument from declaration.
3559 (_bfd_generic_reloc_link_order): Declare.
3560 (_bfd_count_link_order_relocs): Declare.

3571 allocating space for relocations. Handle them in link_order loop.
3572 (ecoff_link_write_external): Set the storage class of a defined
3573 linker created symbol based on the section it is in. Correct
3574 bfd_link_hash_weak case to use .sc rather than .st.
3575 (ecoff_reloc_link_order): New function.
3576 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3578 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3587 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3589 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3591 * som.c (bfd_section_from_som_symbol): Only to do the value
3592 comparison for function symbols within executables.
3594 * som.c (bfd_section_from_som_symbol): Renamed from
3595 som_section_from_subspace_index. Pass in a native SOM symbol.
3596 For executables, iterate through the sections to find out
3597 which contains the symbol's address rather than using the
3598 symbol_info field. (symbol_info has a different meaning for
3599 dynamicly linked executables.)
3601 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3604 * som.c (som_begin_writing): Fix braino (one call to align
3605 space/subspace data was done unconditionally rather than
3606 just for executables.)
3608 * som.c (som_begin_writing): Align text in all executables to
3609 make HPUX kernel happy. Fixes strip/objcopy for shared
3612 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3614 * som.c (som_begin_writing): Account for alignment needs of
3615 subspaces too when writing executables. Never request a negative
3616 bss size. Fixes some problems with demand paged executables,
3617 still having problems with pure executables and shared executables.
3619 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3621 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3622 bfd_zalloc for rawptr, because later on we may call free, not
3625 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3626 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3627 * cisco-core.c: New file.
3628 * Makefile.in: Change accordingly.
3629 * configure.in: Recognize cisco_core_vec.
3630 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3631 * targets.c: Add cisco_core_vec.
3632 * bfd-in2.h: Rebuilt.
3634 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3636 * som.h (som_copyable_section_data_struct): New structure
3637 containing all the private section information which needs
3638 to be copied from input section to output section during
3640 (som_section_data_struct): Remove several fields now in
3641 som_copyable_section_data_struct. Make the space and
3642 subspace dictionaries be pointers (to save space when
3643 only reading objects).
3645 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3646 some references changed. Allocate a copyable data stucture if
3647 none exists. Store info into the copyable data structure.
3648 (bfd_som_set_subsection_attributes): Likewise.
3649 (som_is_space, som_is_subspace, som_is_container): New functions.
3650 Use these instead of directly accessing private data.
3651 (som_prep_headers): Allocate space and subspace headers here.
3652 Fill in some fields in the space/subspace headers from the
3654 (som_bfd_copy_private_section_data): Only copy the stuff
3655 that we really need to make objcopy and strip work. Allocate
3656 the copy_data structure for the output bfd before copying.
3658 * som.h (struct som_exec_data): New structure to hold exec
3659 info that must be preserved when running objcopy/strip.
3660 (struct somdata): Add new "exec_data" field and accessor
3661 macro. Add some comments on how the various fields are used.
3662 (som_section_data_struct): Make is_space and is_subspace bitfields.
3663 Delete unused subspace_index. All references now use the
3664 target_index field within the section structure itself.
3666 * som.c (make_unique_section): Delete unused declaration.
3667 (som_bfd_copy_private_bfd_data): New function.
3668 (som_object_setup): Allocate space for and save exec information
3669 that needs to be copied during objcopy/strip.
3670 (som_mkobject): Do not allocate space for a file header here.
3671 It is not used when only reading SOM objects.
3672 (som_prep_headers): Allocate space for and attach a file header
3673 to the output bfd. For executables, use the saved system_id
3674 value rather than trying to guess the right value. Do not abort
3675 wwhen setting file_hdr->entry* for executables.
3676 (som_begin_writing): For executables, set the exec_entry and
3678 (som_copy_private_backend_section_data): Always return a value.
3680 * libhppa.h (PA_PAGESIZE): Define.
3682 * som.c (SOM_ALIGN): Define.
3683 (som_begin_writing): If writing an executable, initialize all
3684 fields in the exec header to zero. Update fields in the exec
3685 header as sizes of loadable subspaces are computed. Carefully
3686 preserve alignments when building executables. Actually write the
3687 exec after all the fields are filled in.
3689 * Better long-filename handling. Reads SOM ABI compliant extended
3690 names, but doesn't quite write compliant extended names yet.
3691 * som.c (som_slurp_extended_name_table): Delete function. The
3692 generic code will handle things correctly.
3693 (som_slurp_armap): Seek to the beginning of the next member.
3694 (normalize): New function.
3695 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3696 name table into account when computing the file offsets in the
3697 SOM dictionary. Make sure to align to an even boundary.
3698 (som_write_armap): Initialize the checksum to zero.
3699 (ar_maxchars): Fix. Opps.
3701 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3703 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3704 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3706 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3708 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3709 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3710 * bfd-in2.h: Regenerated.
3712 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3713 this was also named trad_unix_bfd_copy_private_bfd_data.
3715 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3717 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3718 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3719 returns NULL, it is not an error. It's possible that some of
3720 these checks are not necessary (because the size can never be
3721 zero), but putting in the checks is the conservative thing to do
3722 in light of the fact that some of these malloc calls replaced
3723 unchecked alloca calls, in which a zero argument would work fine.
3725 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3727 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3728 duplicate definition.
3729 (osf_core_bfd_is_local_label): Define.
3731 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3732 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3733 failure indication, it merely means there are no relocs.
3735 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3736 after NAME, since SunOS /bin/cc can't handle it.
3738 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3740 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3741 From sukes@glue.umd.edu (Tasuki Hirata).
3743 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3745 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3746 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3747 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3749 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3751 * som.c (som_prep_for_fixups): Detect section symbols based
3752 on either the lack of private data or the symbol flags. Do not
3753 munge section symbol names anymore -- they no longer confuse GDB.
3754 (som_begin_writing): Leave space for an exec header if writing
3756 (som_slurp_symbol_table): Recognize both forms of section symbol
3757 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3758 section symbols to be the name of the section they represent.
3759 Debugging symbols begin with "L$0\001", not just "L$".
3761 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3763 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3765 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3766 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3767 and bfd_is_local_label.
3769 * targets.c: Add new entries to the bfd_target structure.
3771 * bfd.c (bfd_copy_private_bfd_data): New definition.
3773 * section.c (bfd_copy_private_section_data): New definition.

3779 * libbfd.c (bfd_generic_is_local_label): New function.
3781 * *-core.c: Provide default definitions for new functions in
3782 the target vector which all point to bfd_false.
3784 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3785 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3786 Default new vectors for copying private backend data to bfd_true.
3787 Default new vector for determining if a symbol is a local label
3788 to bfd_generic_is_local_label.
3790 * som.c (som_bfd_copy_private_section_data): New function.
3791 (som_bfd_is_local_label): New function.
3792 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3794 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3796 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3798 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3800 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3803 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3804 Indent some of them to GNU standards.
3806 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3807 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3808 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3809 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3810 Update copyright years.
3812 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3814 * som.c (som_prep_for_fixups): A relocation involving the section
3815 symbol for the *ABS* section is really a relocation involving
3817 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3818 undefined symbols. Correctly distinguish between debugger symbols
3819 and section symbols.
3821 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3822 for spaces and subspaces.
3824 * som.c (som_bfd_count_ar_symbols): Fix typo.
3826 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3827 HAS_RELOC based on the object's magic number.
3828 (make_unique_section): Delete function. BFD and its users are
3829 prepared to handle multiple sections with the same name.
3830 (setup_sections): Allocate space on the BFD's obstack to hold
3831 section names. Use bfd_make_setion_anyway rather than the
3832 obsolete make_unique_section.
3833 (som_prep_headers): Choose the correct SOM magic number based
3835 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3837 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3839 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3840 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.

3849 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3850 is always located at the start of the data section to allow
3851 recovery of the dynamic info from a stripped executable.
3852 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3855 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3857 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3858 cruft (like the #pragma alloca for AIX).
3859 In addition to that problem, the C alloca calls xmalloc, which
3860 means checking for being out of memory can't work right. The
3861 following changes remove all uses of alloca from BFD.
3862 * hosts/solaris2.h: Remove alloca cruft.
3863 * som.c: Replace alloca with a fixed size auto array.

3868 * linker.c: Replace alloca with obstack_alloc.
3869 * libbfd.h: Rebuilt.
3871 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3873 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3876 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3878 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3879 Elf*_Off typedefs by their expansion, the typedefs have been
3880 removed from include/elf/internal.h.
3881 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3882 SHT_PROGBITS section.
3884 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3886 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
3888 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3890 * configure.host: Recognize i[34]86-sequent-*.
3892 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3893 return from bfd_seek indicates an error.

4212 bother processing them.
4213 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4916 The sparc (and possibly other?) NLM format requires a different
4917 way to write exports, so add a write_export field to the backend
4918 data (and set it to NULL for everything but the sparc).
