1036 an empty .plt section.
1037 (elf32_sparc_relocate_section): For a GOT reloc against a global
1038 symbol when no dynamic object was seen, initialize the contents of

4668 For executables, iterate through the sections to find out
4669 which contains the symbol's address rather than using the
4670 symbol_info field. (symbol_info has a different meaning for
4671 dynamicly linked executables.)
4673 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4676 * som.c (som_begin_writing): Fix braino (one call to align

4709 containing all the private section information which needs
4710 to be copied from input section to output section during
4712 (som_section_data_struct): Remove several fields now in
4713 som_copyable_section_data_struct. Make the space and
4714 subspace dictionaries be pointers (to save space when
4715 only reading objects).
4717 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4718 some references changed. Allocate a copyable data stucture if
4719 none exists. Store info into the copyable data structure.
4720 (bfd_som_set_subsection_attributes): Likewise.
4721 (som_is_space, som_is_subspace, som_is_container): New functions.
4722 Use these instead of directly accessing private data.
4723 (som_prep_headers): Allocate space and subspace headers here.
4724 Fill in some fields in the space/subspace headers from the
4726 (som_bfd_copy_private_section_data): Only copy the stuff
4727 that we really need to make objcopy and strip work. Allocate
4728 the copy_data structure for the output bfd before copying.
4730 * som.h (struct som_exec_data): New structure to hold exec
4731 info that must be preserved when running objcopy/strip.
4732 (struct somdata): Add new "exec_data" field and accessor
4733 macro. Add some comments on how the various fields are used.
4734 (som_section_data_struct): Make is_space and is_subspace bitfields.
4735 Delete unused subspace_index. All references now use the
4736 target_index field within the section structure itself.
4738 * som.c (make_unique_section): Delete unused declaration.
4739 (som_bfd_copy_private_bfd_data): New function.
4740 (som_object_setup): Allocate space for and save exec information
4741 that needs to be copied during objcopy/strip.
4742 (som_mkobject): Do not allocate space for a file header here.
4743 It is not used when only reading SOM objects.
4744 (som_prep_headers): Allocate space for and attach a file header
4745 to the output bfd. For executables, use the saved system_id
4746 value rather than trying to guess the right value. Do not abort
4747 wwhen setting file_hdr->entry* for executables.
4748 (som_begin_writing): For executables, set the exec_entry and
4750 (som_copy_private_backend_section_data): Always return a value.
4752 * libhppa.h (PA_PAGESIZE): Define.
4754 * som.c (SOM_ALIGN): Define.
4755 (som_begin_writing): If writing an executable, initialize all
4756 fields in the exec header to zero. Update fields in the exec
4757 header as sizes of loadable subspaces are computed. Carefully
4758 preserve alignments when building executables. Actually write the
4759 exec after all the fields are filled in.
4761 * Better long-filename handling. Reads SOM ABI compliant extended
4762 names, but doesn't quite write compliant extended names yet.
4763 * som.c (som_slurp_extended_name_table): Delete function. The
4764 generic code will handle things correctly.
4765 (som_slurp_armap): Seek to the beginning of the next member.
4766 (normalize): New function.
4767 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4768 name table into account when computing the file offsets in the
4769 SOM dictionary. Make sure to align to an even boundary.
4770 (som_write_armap): Initialize the checksum to zero.
4771 (ar_maxchars): Fix. Opps.
4773 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4775 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4776 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4778 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4780 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4781 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4782 * bfd-in2.h: Regenerated.
4784 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4785 this was also named trad_unix_bfd_copy_private_bfd_data.
4787 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4789 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4790 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4791 returns NULL, it is not an error. It's possible that some of
4792 these checks are not necessary (because the size can never be
4793 zero), but putting in the checks is the conservative thing to do
4794 in light of the fact that some of these malloc calls replaced
4795 unchecked alloca calls, in which a zero argument would work fine.
4797 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4799 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4800 duplicate definition.

4803 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4804 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4805 failure indication, it merely means there are no relocs.
4807 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4808 after NAME, since SunOS /bin/cc can't handle it.
4810 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4812 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4813 From sukes@glue.umd.edu (Tasuki Hirata).
4815 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4817 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4818 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4819 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4821 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4823 * som.c (som_prep_for_fixups): Detect section symbols based
4824 on either the lack of private data or the symbol flags. Do not
4825 munge section symbol names anymore -- they no longer confuse GDB.
4826 (som_begin_writing): Leave space for an exec header if writing
4828 (som_slurp_symbol_table): Recognize both forms of section symbol
4829 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4830 section symbols to be the name of the section they represent.
4831 Debugging symbols begin with "L$0\001", not just "L$".
4833 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4835 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4837 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4838 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4839 and bfd_is_local_label.
4841 * targets.c: Add new entries to the bfd_target structure.
4843 * bfd.c (bfd_copy_private_bfd_data): New definition.

4854 the target vector which all point to bfd_false.
4856 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4857 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4858 Default new vectors for copying private backend data to bfd_true.
4859 Default new vector for determining if a symbol is a local label
4860 to bfd_generic_is_local_label.
4862 * som.c (som_bfd_copy_private_section_data): New function.
4863 (som_bfd_is_local_label): New function.
4864 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4866 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4868 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4870 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4872 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4875 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4876 Indent some of them to GNU standards.
4878 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4879 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4880 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4881 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4882 Update copyright years.
4884 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4886 * som.c (som_prep_for_fixups): A relocation involving the section
4887 symbol for the *ABS* section is really a relocation involving
4889 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4890 undefined symbols. Correctly distinguish between debugger symbols
4891 and section symbols.
4893 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4894 for spaces and subspaces.
4896 * som.c (som_bfd_count_ar_symbols): Fix typo.
4898 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4899 HAS_RELOC based on the object's magic number.
4900 (make_unique_section): Delete function. BFD and its users are
4901 prepared to handle multiple sections with the same name.
4902 (setup_sections): Allocate space on the BFD's obstack to hold
4903 section names. Use bfd_make_setion_anyway rather than the
4904 obsolete make_unique_section.
4905 (som_prep_headers): Choose the correct SOM magic number based
4907 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4927 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4929 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4930 cruft (like the #pragma alloca for AIX).
4931 In addition to that problem, the C alloca calls xmalloc, which
4932 means checking for being out of memory can't work right. The
4933 following changes remove all uses of alloca from BFD.
4934 * hosts/solaris2.h: Remove alloca cruft.
4935 * som.c: Replace alloca with a fixed size auto array.

4948 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4950 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4951 Elf*_Off typedefs by their expansion, the typedefs have been
4952 removed from include/elf/internal.h.
4953 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4954 SHT_PROGBITS section.
4956 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4967 TRAD_CORE_STACK_OFFSET.
4968 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4969 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4971 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4973 * som.[ch]: Do not include libhppa.h in som.c, instead include
4976 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4977 include it in elf32-hppa.h.
4979 * som.c (log2): Return -1 on error rather than aborting.
4980 (setup_sections): Bubble up an error from log2.
4982 * Changes to make HP C compiler happy in both traditional
4984 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4986 (bfd_som_set_section_attributes): Use unsigned int rather than
4987 unsigned char to avoid GNU-C extensions.
4988 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4989 or failure rather than aborting on failure.
4991 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4993 (bfd_som_attach_aux_hdr): Add prototype.
4994 (hppa_som-gen_reloc_type): Likewise.

5028 unused symbols argument.
5030 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5032 Set reloc->sym_ptr_ptr appropriately.
5033 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5034 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5035 argument. Use the output symbols when canonicalizing the relocs,
5036 creating them if necessary.
5038 * linker.c (_bfd_generic_link_output_symbols): Do not
5039 rebuild/clobber the output symbols if they already exist.
5041 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5043 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5057 Add FIXMEs for unresolved problems. Use enums rather than
5058 #defines for lots of things. Merge two functions which build
5059 linker stubs into a single function (so they can easily share a
5060 ton of common code).
5062 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5064 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5065 avoid depending upon right shifts of signed numbers, and to
5066 correct handling of src_mask with lower bits zero.

5098 (elf_hppa_final_processing): Add extern decl.
5100 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5101 comments. PARAMize some static functions. Delete unused functions.

5105 each case separately. Abort for bad errors until we get error
5106 code propogation working. Work on spacing and indention problems.

5108 COMPLEX relocation support (it's never used anyway).
5109 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

5152 * elfcode.h (alloca): Delete declaration.
5154 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5155 number rather than HP9000S800_ID. Note som.c is careful
5156 to make sure CPU_PA_RISC1_0 is always defined.
5158 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5160 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5179 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
5180 and bss_size bfd_size_type instead of unsigned long. Make
5181 text_start and data_start bfd_vma instead of unsigned long.

5698 * srec.c (srec_write_record): Put CONST keyword for "src" before
5699 "unsigned", some compilers don't like it after "unsigned".
5700 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5818 (only testing for m68k and vax at the moment); do verify that the
5819 preprocessor didn't trash the arch name inside the string version.

5850 bfd_som_set_subsection_attributes): Change parameters from char
5851 to int. Following a prototype with an old-style function definition

5958 use get_value to get the symbol value and check for undefined
5960 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5961 undefined, look it up in the linker hash table.
5963 * aoutx.h (translate_symbol_table): The string index 0 has a

5988 The sparc (and possibly other?) NLM format requires a different
5989 way to write exports, so add a write_export field to the backend
5990 data (and set it to NULL for everything but the sparc).
