1104 an empty .plt section.
1105 (elf32_sparc_relocate_section): For a GOT reloc against a global
1106 symbol when no dynamic object was seen, initialize the contents of
1107 the .got section. For a GOT reloc against a local symbol, only

4766 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4767 * cisco-core.c: New file.
4768 * Makefile.in: Change accordingly.
4769 * configure.in: Recognize cisco_core_vec.
4770 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4771 * targets.c: Add cisco_core_vec.
4772 * bfd-in2.h: Rebuilt.
4774 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4776 * som.h (som_copyable_section_data_struct): New structure
4777 containing all the private section information which needs
4778 to be copied from input section to output section during
4780 (som_section_data_struct): Remove several fields now in
4781 som_copyable_section_data_struct. Make the space and
4782 subspace dictionaries be pointers (to save space when
4783 only reading objects).
4785 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4786 some references changed. Allocate a copyable data stucture if
4787 none exists. Store info into the copyable data structure.
4788 (bfd_som_set_subsection_attributes): Likewise.
4789 (som_is_space, som_is_subspace, som_is_container): New functions.
4790 Use these instead of directly accessing private data.
4791 (som_prep_headers): Allocate space and subspace headers here.
4792 Fill in some fields in the space/subspace headers from the
4794 (som_bfd_copy_private_section_data): Only copy the stuff
4795 that we really need to make objcopy and strip work. Allocate
4796 the copy_data structure for the output bfd before copying.
4798 * som.h (struct som_exec_data): New structure to hold exec
4799 info that must be preserved when running objcopy/strip.
4800 (struct somdata): Add new "exec_data" field and accessor
4801 macro. Add some comments on how the various fields are used.
4802 (som_section_data_struct): Make is_space and is_subspace bitfields.
4803 Delete unused subspace_index. All references now use the
4804 target_index field within the section structure itself.
4806 * som.c (make_unique_section): Delete unused declaration.
4807 (som_bfd_copy_private_bfd_data): New function.
4808 (som_object_setup): Allocate space for and save exec information
4809 that needs to be copied during objcopy/strip.
4810 (som_mkobject): Do not allocate space for a file header here.
4811 It is not used when only reading SOM objects.
4812 (som_prep_headers): Allocate space for and attach a file header
4813 to the output bfd. For executables, use the saved system_id
4814 value rather than trying to guess the right value. Do not abort
4815 wwhen setting file_hdr->entry* for executables.
4816 (som_begin_writing): For executables, set the exec_entry and
4818 (som_copy_private_backend_section_data): Always return a value.
4820 * libhppa.h (PA_PAGESIZE): Define.
4822 * som.c (SOM_ALIGN): Define.
4823 (som_begin_writing): If writing an executable, initialize all
4824 fields in the exec header to zero. Update fields in the exec
4825 header as sizes of loadable subspaces are computed. Carefully
4826 preserve alignments when building executables. Actually write the
4827 exec after all the fields are filled in.
4829 * Better long-filename handling. Reads SOM ABI compliant extended
4830 names, but doesn't quite write compliant extended names yet.
4831 * som.c (som_slurp_extended_name_table): Delete function. The
4832 generic code will handle things correctly.
4833 (som_slurp_armap): Seek to the beginning of the next member.
4834 (normalize): New function.
4835 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4836 name table into account when computing the file offsets in the
4837 SOM dictionary. Make sure to align to an even boundary.
4838 (som_write_armap): Initialize the checksum to zero.
4839 (ar_maxchars): Fix. Opps.
4841 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4843 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4844 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4846 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4848 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4849 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4850 * bfd-in2.h: Regenerated.
4852 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4853 this was also named trad_unix_bfd_copy_private_bfd_data.
4855 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4857 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4858 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4859 returns NULL, it is not an error. It's possible that some of
4860 these checks are not necessary (because the size can never be
4861 zero), but putting in the checks is the conservative thing to do
4862 in light of the fact that some of these malloc calls replaced
4863 unchecked alloca calls, in which a zero argument would work fine.
4865 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4867 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4868 duplicate definition.
4869 (osf_core_bfd_is_local_label): Define.
4871 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4872 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4873 failure indication, it merely means there are no relocs.
4875 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4876 after NAME, since SunOS /bin/cc can't handle it.
4878 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4880 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4881 From sukes@glue.umd.edu (Tasuki Hirata).
4883 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4885 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4886 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4887 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4889 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4891 * som.c (som_prep_for_fixups): Detect section symbols based
4892 on either the lack of private data or the symbol flags. Do not
4893 munge section symbol names anymore -- they no longer confuse GDB.
4894 (som_begin_writing): Leave space for an exec header if writing
4896 (som_slurp_symbol_table): Recognize both forms of section symbol
4897 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4898 section symbols to be the name of the section they represent.
4899 Debugging symbols begin with "L$0\001", not just "L$".
4901 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4903 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4905 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4906 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4907 and bfd_is_local_label.
4909 * targets.c: Add new entries to the bfd_target structure.
4911 * bfd.c (bfd_copy_private_bfd_data): New definition.

4919 * libbfd.c (bfd_generic_is_local_label): New function.
4921 * *-core.c: Provide default definitions for new functions in
4922 the target vector which all point to bfd_false.
4924 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4925 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4926 Default new vectors for copying private backend data to bfd_true.
4927 Default new vector for determining if a symbol is a local label
4928 to bfd_generic_is_local_label.
4930 * som.c (som_bfd_copy_private_section_data): New function.
4931 (som_bfd_is_local_label): New function.
4932 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4934 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4936 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4938 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4940 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4943 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4944 Indent some of them to GNU standards.
4946 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4947 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4948 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4949 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4950 Update copyright years.
4952 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4954 * som.c (som_prep_for_fixups): A relocation involving the section
4955 symbol for the *ABS* section is really a relocation involving
4957 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4958 undefined symbols. Correctly distinguish between debugger symbols
4959 and section symbols.
4961 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4962 for spaces and subspaces.
4964 * som.c (som_bfd_count_ar_symbols): Fix typo.
4966 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4967 HAS_RELOC based on the object's magic number.
4968 (make_unique_section): Delete function. BFD and its users are
4969 prepared to handle multiple sections with the same name.
4970 (setup_sections): Allocate space on the BFD's obstack to hold
4971 section names. Use bfd_make_setion_anyway rather than the
4972 obsolete make_unique_section.
4973 (som_prep_headers): Choose the correct SOM magic number based
4975 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4989 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4990 is always located at the start of the data section to allow
4991 recovery of the dynamic info from a stripped executable.
4992 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4995 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4997 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4998 cruft (like the #pragma alloca for AIX).
4999 In addition to that problem, the C alloca calls xmalloc, which
5000 means checking for being out of memory can't work right. The
5001 following changes remove all uses of alloca from BFD.
5002 * hosts/solaris2.h: Remove alloca cruft.
5003 * som.c: Replace alloca with a fixed size auto array.
5004 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5005 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5006 sunos.c: Replace alloca with malloc and appropriate error checking and
5008 * linker.c: Replace alloca with obstack_alloc.
5009 * libbfd.h: Rebuilt.
5011 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5013 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5016 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5018 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5019 Elf*_Off typedefs by their expansion, the typedefs have been
5020 removed from include/elf/internal.h.
5021 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5022 SHT_PROGBITS section.
5024 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5026 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5032 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5033 return from bfd_seek indicates an error.
5034 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5035 TRAD_CORE_STACK_OFFSET.
5036 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5037 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5039 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5041 * som.[ch]: Do not include libhppa.h in som.c, instead include
5044 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5045 include it in elf32-hppa.h.
5047 * som.c (log2): Return -1 on error rather than aborting.
5048 (setup_sections): Bubble up an error from log2.
5050 * Changes to make HP C compiler happy in both traditional
5052 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5054 (bfd_som_set_section_attributes): Use unsigned int rather than
5055 unsigned char to avoid GNU-C extensions.
5056 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5057 or failure rather than aborting on failure.
5059 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5061 (bfd_som_attach_aux_hdr): Add prototype.
5062 (hppa_som-gen_reloc_type): Likewise.

5065 (hppa_look_for_stubs_in_section): Do not return false on failure
5066 until rest of code is ready to handle it. Abort for now.

5091 action in case where caller specified no argument relocation.
5092 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5093 right in the original relocation and the stub's relocation.
5095 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5096 unused symbols argument.
5098 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5100 Set reloc->sym_ptr_ptr appropriately.
5101 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5102 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5103 argument. Use the output symbols when canonicalizing the relocs,
5104 creating them if necessary.
5106 * linker.c (_bfd_generic_link_output_symbols): Do not
5107 rebuild/clobber the output symbols if they already exist.
5109 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5111 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5113 * bfd-in2.h: Rebuilt.
5115 * srec.c (hex_value): Always set to a size of 256 bytes.
5116 (srec_init): Cosmetic changes.
5118 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5121 PARAMize and staticize rest of functions. Delete unused
5122 functions. Delete unused/unnecessary arguments to some functions.
5123 Group static vars together. Abort for bad errors until we have
5124 error code propogation working. Work on spacing and indention.
5125 Add FIXMEs for unresolved problems. Use enums rather than
5126 #defines for lots of things. Merge two functions which build
5127 linker stubs into a single function (so they can easily share a
5128 ton of common code).
5130 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5132 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5133 avoid depending upon right shifts of signed numbers, and to
5134 correct handling of src_mask with lower bits zero.
5136 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

5164 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5165 (elf_hppa_tc_make_sections): Likewise.
5166 (elf_hppa_final_processing): Add extern decl.
5168 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5169 comments. PARAMize some static functions. Delete unused functions.
5170 Delete unused/unnecessary arguments to many functions. Group
5171 static vars together. Collapse common case statements together
5172 in many places. Use default case when possible instead of listing
5173 each case separately. Abort for bad errors until we get error
5174 code propogation working. Work on spacing and indention problems.
5175 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5176 COMPLEX relocation support (it's never used anyway).
5177 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5178 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5179 (elf_hppa_tc_make_sections): Likewise.
5181 * format.c (bfd_check_format_matches): Initialize matching_vector

5192 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
5194 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

5215 * elfcode.h (elf_core_file_p): Check for core file e_machine match
5216 like in elf_object_p.

6026 use get_value to get the symbol value and check for undefined
6028 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6029 undefined, look it up in the linker hash table.
6031 * aoutx.h (translate_symbol_table): The string index 0 has a

6056 The sparc (and possibly other?) NLM format requires a different
6057 way to write exports, so add a write_export field to the backend
6058 data (and set it to NULL for everything but the sparc).
