1965 an empty .plt section.
1966 (elf32_sparc_relocate_section): For a GOT reloc against a global
1967 symbol when no dynamic object was seen, initialize the contents of

1988 storage class slightly more verbose. It's not clear how many
1989 characters I can justify using up, but before this change they

5600 dynamicly linked executables.)
5602 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5605 * som.c (som_begin_writing): Fix braino (one call to align

5643 subspace dictionaries be pointers (to save space when
5644 only reading objects).

5647 some references changed. Allocate a copyable data stucture if
5648 none exists. Store info into the copyable data structure.

5653 Fill in some fields in the space/subspace headers from the
5655 (som_bfd_copy_private_section_data): Only copy the stuff
5656 that we really need to make objcopy and strip work. Allocate
5657 the copy_data structure for the output bfd before copying.
5659 * som.h (struct som_exec_data): New structure to hold exec
5660 info that must be preserved when running objcopy/strip.

5662 macro. Add some comments on how the various fields are used.
5663 (som_section_data_struct): Make is_space and is_subspace bitfields.

5672 It is not used when only reading SOM objects.
5673 (som_prep_headers): Allocate space for and attach a file header
5674 to the output bfd. For executables, use the saved system_id
5675 value rather than trying to guess the right value. Do not abort
5676 wwhen setting file_hdr->entry* for executables.
5677 (som_begin_writing): For executables, set the exec_entry and
5679 (som_copy_private_backend_section_data): Always return a value.
5681 * libhppa.h (PA_PAGESIZE): Define.

5684 (som_begin_writing): If writing an executable, initialize all
5685 fields in the exec header to zero. Update fields in the exec
5686 header as sizes of loadable subspaces are computed. Carefully
5687 preserve alignments when building executables. Actually write the
5688 exec after all the fields are filled in.
5690 * Better long-filename handling. Reads SOM ABI compliant extended
5691 names, but doesn't quite write compliant extended names yet.
5692 * som.c (som_slurp_extended_name_table): Delete function. The
5693 generic code will handle things correctly.
5694 (som_slurp_armap): Seek to the beginning of the next member.
5695 (normalize): New function.
5696 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5697 name table into account when computing the file offsets in the
5698 SOM dictionary. Make sure to align to an even boundary.
5699 (som_write_armap): Initialize the checksum to zero.
5700 (ar_maxchars): Fix. Opps.
5702 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5704 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5705 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5707 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5709 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5710 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5711 * bfd-in2.h: Regenerated.
5713 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5714 this was also named trad_unix_bfd_copy_private_bfd_data.
5716 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5718 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5719 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5720 returns NULL, it is not an error. It's possible that some of
5721 these checks are not necessary (because the size can never be
5722 zero), but putting in the checks is the conservative thing to do
5723 in light of the fact that some of these malloc calls replaced
5724 unchecked alloca calls, in which a zero argument would work fine.
5726 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5728 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5729 duplicate definition.

5732 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5733 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5734 failure indication, it merely means there are no relocs.
5736 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5737 after NAME, since SunOS /bin/cc can't handle it.
5739 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5741 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5742 From sukes@glue.umd.edu (Tasuki Hirata).
5744 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5746 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5747 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5748 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5750 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5752 * som.c (som_prep_for_fixups): Detect section symbols based
5753 on either the lack of private data or the symbol flags. Do not
5754 munge section symbol names anymore -- they no longer confuse GDB.
5755 (som_begin_writing): Leave space for an exec header if writing
5757 (som_slurp_symbol_table): Recognize both forms of section symbol
5758 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5759 section symbols to be the name of the section they represent.
5760 Debugging symbols begin with "L$0\001", not just "L$".
5762 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5767 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5768 and bfd_is_local_label.

5786 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5787 Default new vectors for copying private backend data to bfd_true.
5788 Default new vector for determining if a symbol is a local label
5789 to bfd_generic_is_local_label.
5791 * som.c (som_bfd_copy_private_section_data): New function.
5792 (som_bfd_is_local_label): New function.

5795 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5797 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5799 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5801 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5804 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5805 Indent some of them to GNU standards.
5807 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5808 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5809 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5810 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5811 Update copyright years.
5813 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5815 * som.c (som_prep_for_fixups): A relocation involving the section
5816 symbol for the *ABS* section is really a relocation involving
5818 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5819 undefined symbols. Correctly distinguish between debugger symbols
5820 and section symbols.
5822 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5823 for spaces and subspaces.
5825 * som.c (som_bfd_count_ar_symbols): Fix typo.
5827 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5828 HAS_RELOC based on the object's magic number.
5829 (make_unique_section): Delete function. BFD and its users are
5830 prepared to handle multiple sections with the same name.
5831 (setup_sections): Allocate space on the BFD's obstack to hold
5832 section names. Use bfd_make_setion_anyway rather than the
5833 obsolete make_unique_section.
5834 (som_prep_headers): Choose the correct SOM magic number based
5836 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5856 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5858 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5859 cruft (like the #pragma alloca for AIX).
5860 In addition to that problem, the C alloca calls xmalloc, which
5861 means checking for being out of memory can't work right. The
5862 following changes remove all uses of alloca from BFD.
5863 * hosts/solaris2.h: Remove alloca cruft.
5864 * som.c: Replace alloca with a fixed size auto array.

5877 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5879 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5880 Elf*_Off typedefs by their expansion, the typedefs have been
5881 removed from include/elf/internal.h.
5882 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5883 SHT_PROGBITS section.

5896 TRAD_CORE_STACK_OFFSET.
5897 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5898 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

5902 * som.[ch]: Do not include libhppa.h in som.c, instead include
5905 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5906 include it in elf32-hppa.h.
5908 * som.c (log2): Return -1 on error rather than aborting.
5909 (setup_sections): Bubble up an error from log2.
5911 * Changes to make HP C compiler happy in both traditional
5913 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5915 (bfd_som_set_section_attributes): Use unsigned int rather than
5916 unsigned char to avoid GNU-C extensions.
5917 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5918 or failure rather than aborting on failure.
5920 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5922 (bfd_som_attach_aux_hdr): Add prototype.
5923 (hppa_som-gen_reloc_type): Likewise.

5963 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5964 argument. Use the output symbols when canonicalizing the relocs,
5965 creating them if necessary.
5967 * linker.c (_bfd_generic_link_output_symbols): Do not
5968 rebuild/clobber the output symbols if they already exist.

5987 #defines for lots of things. Merge two functions which build
5988 linker stubs into a single function (so they can easily share a
5989 ton of common code).
5991 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5993 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5994 avoid depending upon right shifts of signed numbers, and to
5995 correct handling of src_mask with lower bits zero.

6037 COMPLEX relocation support (it's never used anyway).
6038 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

6085 to make sure CPU_PA_RISC1_0 is always defined.
6087 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
6089 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

6627 * srec.c (srec_write_record): Put CONST keyword for "src" before
6628 "unsigned", some compilers don't like it after "unsigned".
6629 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

6747 (only testing for m68k and vax at the moment); do verify that the
6748 preprocessor didn't trash the arch name inside the string version.

6779 bfd_som_set_subsection_attributes): Change parameters from char
6780 to int. Following a prototype with an old-style function definition

6887 use get_value to get the symbol value and check for undefined
6889 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6890 undefined, look it up in the linker hash table.
6892 * aoutx.h (translate_symbol_table): The string index 0 has a

6917 The sparc (and possibly other?) NLM format requires a different
6918 way to write exports, so add a write_export field to the backend
6919 data (and set it to NULL for everything but the sparc).

6969 read_dynamic_relocs fields.
6970 * aout-target.h (MY(backend_data)): Initialize
