1030 an empty .plt section.
1031 (elf32_sparc_relocate_section): For a GOT reloc against a global
1032 symbol when no dynamic object was seen, initialize the contents of
1033 the .got section. For a GOT reloc against a local symbol, only

1053 storage class slightly more verbose. It's not clear how many
1054 characters I can justify using up, but before this change they

4663 which contains the symbol's address rather than using the
4664 symbol_info field. (symbol_info has a different meaning for
4665 dynamicly linked executables.)
4667 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4670 * som.c (som_begin_writing): Fix braino (one call to align

4707 som_copyable_section_data_struct. Make the space and
4708 subspace dictionaries be pointers (to save space when
4709 only reading objects).
4711 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4712 some references changed. Allocate a copyable data stucture if
4713 none exists. Store info into the copyable data structure.

4715 (som_is_space, som_is_subspace, som_is_container): New functions.
4716 Use these instead of directly accessing private data.
4717 (som_prep_headers): Allocate space and subspace headers here.
4718 Fill in some fields in the space/subspace headers from the
4720 (som_bfd_copy_private_section_data): Only copy the stuff
4721 that we really need to make objcopy and strip work. Allocate
4722 the copy_data structure for the output bfd before copying.
4724 * som.h (struct som_exec_data): New structure to hold exec
4725 info that must be preserved when running objcopy/strip.
4726 (struct somdata): Add new "exec_data" field and accessor
4727 macro. Add some comments on how the various fields are used.
4728 (som_section_data_struct): Make is_space and is_subspace bitfields.

4737 It is not used when only reading SOM objects.
4738 (som_prep_headers): Allocate space for and attach a file header
4739 to the output bfd. For executables, use the saved system_id
4740 value rather than trying to guess the right value. Do not abort
4741 wwhen setting file_hdr->entry* for executables.
4742 (som_begin_writing): For executables, set the exec_entry and
4744 (som_copy_private_backend_section_data): Always return a value.
4746 * libhppa.h (PA_PAGESIZE): Define.

4749 (som_begin_writing): If writing an executable, initialize all
4750 fields in the exec header to zero. Update fields in the exec
4751 header as sizes of loadable subspaces are computed. Carefully
4752 preserve alignments when building executables. Actually write the
4753 exec after all the fields are filled in.
4755 * Better long-filename handling. Reads SOM ABI compliant extended
4756 names, but doesn't quite write compliant extended names yet.
4757 * som.c (som_slurp_extended_name_table): Delete function. The
4758 generic code will handle things correctly.
4759 (som_slurp_armap): Seek to the beginning of the next member.
4760 (normalize): New function.
4761 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4762 name table into account when computing the file offsets in the
4763 SOM dictionary. Make sure to align to an even boundary.
4764 (som_write_armap): Initialize the checksum to zero.
4765 (ar_maxchars): Fix. Opps.
4767 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4769 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4770 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

4774 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4775 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4776 * bfd-in2.h: Regenerated.
4778 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4779 this was also named trad_unix_bfd_copy_private_bfd_data.
4781 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4783 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4784 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4785 returns NULL, it is not an error. It's possible that some of
4786 these checks are not necessary (because the size can never be
4787 zero), but putting in the checks is the conservative thing to do
4788 in light of the fact that some of these malloc calls replaced
4789 unchecked alloca calls, in which a zero argument would work fine.
4791 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4793 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4794 duplicate definition.

4797 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4798 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4799 failure indication, it merely means there are no relocs.
4801 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4802 after NAME, since SunOS /bin/cc can't handle it.
4804 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4806 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4807 From sukes@glue.umd.edu (Tasuki Hirata).
4809 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4811 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4812 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4813 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4815 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4817 * som.c (som_prep_for_fixups): Detect section symbols based
4818 on either the lack of private data or the symbol flags. Do not
4819 munge section symbol names anymore -- they no longer confuse GDB.
4820 (som_begin_writing): Leave space for an exec header if writing
4822 (som_slurp_symbol_table): Recognize both forms of section symbol
4823 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4824 section symbols to be the name of the section they represent.
4825 Debugging symbols begin with "L$0\001", not just "L$".
4827 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4832 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4833 and bfd_is_local_label.

4851 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4852 Default new vectors for copying private backend data to bfd_true.
4853 Default new vector for determining if a symbol is a local label
4854 to bfd_generic_is_local_label.
4856 * som.c (som_bfd_copy_private_section_data): New function.
4857 (som_bfd_is_local_label): New function.
4858 (som_bfd_copy_private_bfd_data): For now default to bfd_true.

4862 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4864 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4866 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4869 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4870 Indent some of them to GNU standards.
4872 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4873 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4874 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4875 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4876 Update copyright years.
4878 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4880 * som.c (som_prep_for_fixups): A relocation involving the section
4881 symbol for the *ABS* section is really a relocation involving
4883 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4884 undefined symbols. Correctly distinguish between debugger symbols
4885 and section symbols.
4887 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4888 for spaces and subspaces.
4890 * som.c (som_bfd_count_ar_symbols): Fix typo.
4892 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4893 HAS_RELOC based on the object's magic number.
4894 (make_unique_section): Delete function. BFD and its users are
4895 prepared to handle multiple sections with the same name.
4896 (setup_sections): Allocate space on the BFD's obstack to hold
4897 section names. Use bfd_make_setion_anyway rather than the
4898 obsolete make_unique_section.
4899 (som_prep_headers): Choose the correct SOM magic number based
4901 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4921 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4923 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4924 cruft (like the #pragma alloca for AIX).
4925 In addition to that problem, the C alloca calls xmalloc, which
4926 means checking for being out of memory can't work right. The
4927 following changes remove all uses of alloca from BFD.
4928 * hosts/solaris2.h: Remove alloca cruft.
4929 * som.c: Replace alloca with a fixed size auto array.

4942 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4944 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4945 Elf*_Off typedefs by their expansion, the typedefs have been
4946 removed from include/elf/internal.h.
4947 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4948 SHT_PROGBITS section.

4961 TRAD_CORE_STACK_OFFSET.
4962 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4963 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

4967 * som.[ch]: Do not include libhppa.h in som.c, instead include
4970 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4971 include it in elf32-hppa.h.
4973 * som.c (log2): Return -1 on error rather than aborting.
4974 (setup_sections): Bubble up an error from log2.
4976 * Changes to make HP C compiler happy in both traditional
4978 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4980 (bfd_som_set_section_attributes): Use unsigned int rather than
4981 unsigned char to avoid GNU-C extensions.
4982 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4983 or failure rather than aborting on failure.
4985 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4987 (bfd_som_attach_aux_hdr): Add prototype.
4988 (hppa_som-gen_reloc_type): Likewise.

5028 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5029 argument. Use the output symbols when canonicalizing the relocs,
5030 creating them if necessary.
5032 * linker.c (_bfd_generic_link_output_symbols): Do not
5033 rebuild/clobber the output symbols if they already exist.

5052 #defines for lots of things. Merge two functions which build
5053 linker stubs into a single function (so they can easily share a
5054 ton of common code).
5056 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5058 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to

5102 COMPLEX relocation support (it's never used anyway).
5103 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

5150 to make sure CPU_PA_RISC1_0 is always defined.
5152 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5154 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5693 "unsigned", some compilers don't like it after "unsigned".
5694 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5812 (only testing for m68k and vax at the moment); do verify that the
5813 preprocessor didn't trash the arch name inside the string version.

5844 bfd_som_set_subsection_attributes): Change parameters from char
5845 to int. Following a prototype with an old-style function definition

5952 use get_value to get the symbol value and check for undefined
5954 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5955 undefined, look it up in the linker hash table.
5957 * aoutx.h (translate_symbol_table): The string index 0 has a

5982 The sparc (and possibly other?) NLM format requires a different
5983 way to write exports, so add a write_export field to the backend
5984 data (and set it to NULL for everything but the sparc).

6034 read_dynamic_relocs fields.
6035 * aout-target.h (MY(backend_data)): Initialize
