3514 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3516 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3517 reloc, used in embedded PIC code.

3537 _bfd_generic_link_add_symbols but also collect constructors and
3538 destructors by name as collect2 does.

3557 extended name table.
3559 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3561 Support for link_order types which generate relocs in order to
3562 support -Ur in the linker.
3563 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3564 from call to _bfd_generic_link_add_one_symbol.
3565 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3566 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3567 instead of bitsize to add_to_set call back.
3568 (_bfd_generic_final_link): Account for link_order relocs when
3569 allocating space for relocations. Handle them in link_order loop.
3570 (_bfd_generic_reloc_link_order): New function.

3588 allocating space for relocations. Handle them in link_order loop.
3589 (ecoff_link_write_external): Set the storage class of a defined
3590 linker created symbol based on the section it is in. Correct
3591 bfd_link_hash_weak case to use .sc rather than .st.

3604 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3606 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3608 * som.c (bfd_section_from_som_symbol): Only to do the value
3609 comparison for function symbols within executables.
3611 * som.c (bfd_section_from_som_symbol): Renamed from
3612 som_section_from_subspace_index. Pass in a native SOM symbol.
3613 For executables, iterate through the sections to find out
3614 which contains the symbol's address rather than using the
3615 symbol_info field. (symbol_info has a different meaning for
3616 dynamicly linked executables.)
3618 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3621 * som.c (som_begin_writing): Fix braino (one call to align
3622 space/subspace data was done unconditionally rather than
3623 just for executables.)
3625 * som.c (som_begin_writing): Align text in all executables to
3626 make HPUX kernel happy. Fixes strip/objcopy for shared
3629 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3631 * som.c (som_begin_writing): Account for alignment needs of
3632 subspaces too when writing executables. Never request a negative
3633 bss size. Fixes some problems with demand paged executables,
3634 still having problems with pure executables and shared executables.
3636 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3638 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3639 bfd_zalloc for rawptr, because later on we may call free, not
3642 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3643 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3644 * cisco-core.c: New file.
3645 * Makefile.in: Change accordingly.
3646 * configure.in: Recognize cisco_core_vec.
3647 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3648 * targets.c: Add cisco_core_vec.
3649 * bfd-in2.h: Rebuilt.
3651 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3653 * som.h (som_copyable_section_data_struct): New structure
3654 containing all the private section information which needs
3655 to be copied from input section to output section during
3657 (som_section_data_struct): Remove several fields now in
3658 som_copyable_section_data_struct. Make the space and
3659 subspace dictionaries be pointers (to save space when
3660 only reading objects).
3662 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3663 some references changed. Allocate a copyable data stucture if
3664 none exists. Store info into the copyable data structure.
3665 (bfd_som_set_subsection_attributes): Likewise.
3666 (som_is_space, som_is_subspace, som_is_container): New functions.
3667 Use these instead of directly accessing private data.
3668 (som_prep_headers): Allocate space and subspace headers here.
3669 Fill in some fields in the space/subspace headers from the
3671 (som_bfd_copy_private_section_data): Only copy the stuff
3672 that we really need to make objcopy and strip work. Allocate
3673 the copy_data structure for the output bfd before copying.
3675 * som.h (struct som_exec_data): New structure to hold exec
3676 info that must be preserved when running objcopy/strip.
3677 (struct somdata): Add new "exec_data" field and accessor
3678 macro. Add some comments on how the various fields are used.
3679 (som_section_data_struct): Make is_space and is_subspace bitfields.
3680 Delete unused subspace_index. All references now use the
3681 target_index field within the section structure itself.
3683 * som.c (make_unique_section): Delete unused declaration.
3684 (som_bfd_copy_private_bfd_data): New function.
3685 (som_object_setup): Allocate space for and save exec information
3686 that needs to be copied during objcopy/strip.
3687 (som_mkobject): Do not allocate space for a file header here.
3688 It is not used when only reading SOM objects.
3689 (som_prep_headers): Allocate space for and attach a file header
3690 to the output bfd. For executables, use the saved system_id
3691 value rather than trying to guess the right value. Do not abort
3692 wwhen setting file_hdr->entry* for executables.
3693 (som_begin_writing): For executables, set the exec_entry and
3695 (som_copy_private_backend_section_data): Always return a value.
3697 * libhppa.h (PA_PAGESIZE): Define.
3699 * som.c (SOM_ALIGN): Define.
3700 (som_begin_writing): If writing an executable, initialize all
3701 fields in the exec header to zero. Update fields in the exec
3702 header as sizes of loadable subspaces are computed. Carefully
3703 preserve alignments when building executables. Actually write the
3704 exec after all the fields are filled in.
3706 * Better long-filename handling. Reads SOM ABI compliant extended
3707 names, but doesn't quite write compliant extended names yet.
3708 * som.c (som_slurp_extended_name_table): Delete function. The
3709 generic code will handle things correctly.
3710 (som_slurp_armap): Seek to the beginning of the next member.
3711 (normalize): New function.
3712 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3713 name table into account when computing the file offsets in the
3714 SOM dictionary. Make sure to align to an even boundary.
3715 (som_write_armap): Initialize the checksum to zero.
3716 (ar_maxchars): Fix. Opps.
3718 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3720 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3721 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3723 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3725 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3726 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3727 * bfd-in2.h: Regenerated.
3729 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3730 this was also named trad_unix_bfd_copy_private_bfd_data.
3732 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3734 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3735 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3736 returns NULL, it is not an error. It's possible that some of
3737 these checks are not necessary (because the size can never be
3738 zero), but putting in the checks is the conservative thing to do
3739 in light of the fact that some of these malloc calls replaced
3740 unchecked alloca calls, in which a zero argument would work fine.
3742 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3744 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3745 duplicate definition.
3746 (osf_core_bfd_is_local_label): Define.
3748 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3749 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3750 failure indication, it merely means there are no relocs.
3752 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3753 after NAME, since SunOS /bin/cc can't handle it.
3755 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3757 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3758 From sukes@glue.umd.edu (Tasuki Hirata).
3760 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3762 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3763 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3764 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3766 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3768 * som.c (som_prep_for_fixups): Detect section symbols based
3769 on either the lack of private data or the symbol flags. Do not
3770 munge section symbol names anymore -- they no longer confuse GDB.
3771 (som_begin_writing): Leave space for an exec header if writing
3773 (som_slurp_symbol_table): Recognize both forms of section symbol
3774 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3775 section symbols to be the name of the section they represent.
3776 Debugging symbols begin with "L$0\001", not just "L$".
3778 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3780 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3782 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3783 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3784 and bfd_is_local_label.
3786 * targets.c: Add new entries to the bfd_target structure.
3788 * bfd.c (bfd_copy_private_bfd_data): New definition.
3790 * section.c (bfd_copy_private_section_data): New definition.
3792 * syms.c (bfd_is_local_label): New definition.
3794 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3796 * libbfd.c (bfd_generic_is_local_label): New function.
3798 * *-core.c: Provide default definitions for new functions in
3799 the target vector which all point to bfd_false.
3801 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3802 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3803 Default new vectors for copying private backend data to bfd_true.
3804 Default new vector for determining if a symbol is a local label
3805 to bfd_generic_is_local_label.
3807 * som.c (som_bfd_copy_private_section_data): New function.
3808 (som_bfd_is_local_label): New function.
3809 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3811 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3813 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3815 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3817 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3820 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3821 Indent some of them to GNU standards.
3823 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3824 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3825 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3826 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3827 Update copyright years.
3829 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3831 * som.c (som_prep_for_fixups): A relocation involving the section
3832 symbol for the *ABS* section is really a relocation involving
3834 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3835 undefined symbols. Correctly distinguish between debugger symbols
3836 and section symbols.
3838 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3839 for spaces and subspaces.
3841 * som.c (som_bfd_count_ar_symbols): Fix typo.
3843 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3844 HAS_RELOC based on the object's magic number.
3845 (make_unique_section): Delete function. BFD and its users are
3846 prepared to handle multiple sections with the same name.
3847 (setup_sections): Allocate space on the BFD's obstack to hold
3848 section names. Use bfd_make_setion_anyway rather than the
3849 obsolete make_unique_section.
3850 (som_prep_headers): Choose the correct SOM magic number based
3852 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3854 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3856 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3857 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3858 * Makefile.in, configure.in: Corresponding changes.

3862 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3864 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3866 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3867 is always located at the start of the data section to allow
3868 recovery of the dynamic info from a stripped executable.
3869 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3872 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3874 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3875 cruft (like the #pragma alloca for AIX).
3876 In addition to that problem, the C alloca calls xmalloc, which
3877 means checking for being out of memory can't work right. The
3878 following changes remove all uses of alloca from BFD.
3879 * hosts/solaris2.h: Remove alloca cruft.
3880 * som.c: Replace alloca with a fixed size auto array.
3881 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3882 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3883 sunos.c: Replace alloca with malloc and appropriate error checking and
3885 * linker.c: Replace alloca with obstack_alloc.
3886 * libbfd.h: Rebuilt.
3888 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3890 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like

4933 The sparc (and possibly other?) NLM format requires a different
4934 way to write exports, so add a write_export field to the backend
4935 data (and set it to NULL for everything but the sparc).

5179 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
5180 different, so there is no point to providing a generic one.
