1094 an empty .plt section.
1095 (elf32_sparc_relocate_section): For a GOT reloc against a global
1096 symbol when no dynamic object was seen, initialize the contents of
1097 the .got section. For a GOT reloc against a local symbol, only

4761 * targets.c: Add cisco_core_vec.
4762 * bfd-in2.h: Rebuilt.
4764 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4766 * som.h (som_copyable_section_data_struct): New structure
4767 containing all the private section information which needs
4768 to be copied from input section to output section during
4770 (som_section_data_struct): Remove several fields now in
4771 som_copyable_section_data_struct. Make the space and
4772 subspace dictionaries be pointers (to save space when
4773 only reading objects).
4775 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4776 some references changed. Allocate a copyable data stucture if
4777 none exists. Store info into the copyable data structure.
4778 (bfd_som_set_subsection_attributes): Likewise.
4779 (som_is_space, som_is_subspace, som_is_container): New functions.
4780 Use these instead of directly accessing private data.
4781 (som_prep_headers): Allocate space and subspace headers here.
4782 Fill in some fields in the space/subspace headers from the
4784 (som_bfd_copy_private_section_data): Only copy the stuff
4785 that we really need to make objcopy and strip work. Allocate
4786 the copy_data structure for the output bfd before copying.
4788 * som.h (struct som_exec_data): New structure to hold exec
4789 info that must be preserved when running objcopy/strip.
4790 (struct somdata): Add new "exec_data" field and accessor
4791 macro. Add some comments on how the various fields are used.
4792 (som_section_data_struct): Make is_space and is_subspace bitfields.
4793 Delete unused subspace_index. All references now use the
4794 target_index field within the section structure itself.
4796 * som.c (make_unique_section): Delete unused declaration.
4797 (som_bfd_copy_private_bfd_data): New function.
4798 (som_object_setup): Allocate space for and save exec information
4799 that needs to be copied during objcopy/strip.
4800 (som_mkobject): Do not allocate space for a file header here.
4801 It is not used when only reading SOM objects.
4802 (som_prep_headers): Allocate space for and attach a file header
4803 to the output bfd. For executables, use the saved system_id
4804 value rather than trying to guess the right value. Do not abort
4805 wwhen setting file_hdr->entry* for executables.
4806 (som_begin_writing): For executables, set the exec_entry and
4808 (som_copy_private_backend_section_data): Always return a value.
4810 * libhppa.h (PA_PAGESIZE): Define.
4812 * som.c (SOM_ALIGN): Define.
4813 (som_begin_writing): If writing an executable, initialize all
4814 fields in the exec header to zero. Update fields in the exec
4815 header as sizes of loadable subspaces are computed. Carefully
4816 preserve alignments when building executables. Actually write the
4817 exec after all the fields are filled in.
4819 * Better long-filename handling. Reads SOM ABI compliant extended
4820 names, but doesn't quite write compliant extended names yet.
4821 * som.c (som_slurp_extended_name_table): Delete function. The
4822 generic code will handle things correctly.
4823 (som_slurp_armap): Seek to the beginning of the next member.
4824 (normalize): New function.
4825 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4826 name table into account when computing the file offsets in the
4827 SOM dictionary. Make sure to align to an even boundary.
4828 (som_write_armap): Initialize the checksum to zero.
4829 (ar_maxchars): Fix. Opps.
4831 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4833 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4834 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4836 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4838 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4839 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4840 * bfd-in2.h: Regenerated.
4842 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4843 this was also named trad_unix_bfd_copy_private_bfd_data.
4845 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4847 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4848 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4849 returns NULL, it is not an error. It's possible that some of
4850 these checks are not necessary (because the size can never be
4851 zero), but putting in the checks is the conservative thing to do
4852 in light of the fact that some of these malloc calls replaced
4853 unchecked alloca calls, in which a zero argument would work fine.
4855 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4857 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4858 duplicate definition.
4859 (osf_core_bfd_is_local_label): Define.
4861 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4862 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4863 failure indication, it merely means there are no relocs.
4865 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4866 after NAME, since SunOS /bin/cc can't handle it.
4868 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4870 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4871 From sukes@glue.umd.edu (Tasuki Hirata).
4873 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4875 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4876 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4877 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4879 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4881 * som.c (som_prep_for_fixups): Detect section symbols based
4882 on either the lack of private data or the symbol flags. Do not
4883 munge section symbol names anymore -- they no longer confuse GDB.
4884 (som_begin_writing): Leave space for an exec header if writing
4886 (som_slurp_symbol_table): Recognize both forms of section symbol
4887 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4888 section symbols to be the name of the section they represent.
4889 Debugging symbols begin with "L$0\001", not just "L$".
4891 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4893 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4895 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4896 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4897 and bfd_is_local_label.
4899 * targets.c: Add new entries to the bfd_target structure.
4901 * bfd.c (bfd_copy_private_bfd_data): New definition.
4903 * section.c (bfd_copy_private_section_data): New definition.
4905 * syms.c (bfd_is_local_label): New definition.
4907 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4909 * libbfd.c (bfd_generic_is_local_label): New function.
4911 * *-core.c: Provide default definitions for new functions in
4912 the target vector which all point to bfd_false.
4914 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4915 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4916 Default new vectors for copying private backend data to bfd_true.
4917 Default new vector for determining if a symbol is a local label
4918 to bfd_generic_is_local_label.
4920 * som.c (som_bfd_copy_private_section_data): New function.
4921 (som_bfd_is_local_label): New function.
4922 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4924 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4926 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4928 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4930 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4933 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4934 Indent some of them to GNU standards.
4936 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4937 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4938 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4939 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4940 Update copyright years.
4942 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4944 * som.c (som_prep_for_fixups): A relocation involving the section
4945 symbol for the *ABS* section is really a relocation involving
4947 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4948 undefined symbols. Correctly distinguish between debugger symbols
4949 and section symbols.
4951 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4952 for spaces and subspaces.
4954 * som.c (som_bfd_count_ar_symbols): Fix typo.
4956 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4957 HAS_RELOC based on the object's magic number.
4958 (make_unique_section): Delete function. BFD and its users are
4959 prepared to handle multiple sections with the same name.
4960 (setup_sections): Allocate space on the BFD's obstack to hold
4961 section names. Use bfd_make_setion_anyway rather than the
4962 obsolete make_unique_section.
4963 (som_prep_headers): Choose the correct SOM magic number based
4965 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4967 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4969 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4970 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.

4979 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4980 is always located at the start of the data section to allow
4981 recovery of the dynamic info from a stripped executable.
4982 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4985 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4987 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4988 cruft (like the #pragma alloca for AIX).
4989 In addition to that problem, the C alloca calls xmalloc, which
4990 means checking for being out of memory can't work right. The
4991 following changes remove all uses of alloca from BFD.
4992 * hosts/solaris2.h: Remove alloca cruft.
4993 * som.c: Replace alloca with a fixed size auto array.
4994 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4995 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4996 sunos.c: Replace alloca with malloc and appropriate error checking and
4998 * linker.c: Replace alloca with obstack_alloc.
4999 * libbfd.h: Rebuilt.
5001 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5003 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5006 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5008 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5009 Elf*_Off typedefs by their expansion, the typedefs have been
5010 removed from include/elf/internal.h.
5011 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5012 SHT_PROGBITS section.
5014 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5016 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5022 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5023 return from bfd_seek indicates an error.
5024 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5025 TRAD_CORE_STACK_OFFSET.
5026 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5027 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5029 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5031 * som.[ch]: Do not include libhppa.h in som.c, instead include
5034 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5035 include it in elf32-hppa.h.
5037 * som.c (log2): Return -1 on error rather than aborting.
5038 (setup_sections): Bubble up an error from log2.
5040 * Changes to make HP C compiler happy in both traditional
5042 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5044 (bfd_som_set_section_attributes): Use unsigned int rather than
5045 unsigned char to avoid GNU-C extensions.
5046 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5047 or failure rather than aborting on failure.
5049 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5051 (bfd_som_attach_aux_hdr): Add prototype.
5052 (hppa_som-gen_reloc_type): Likewise.
5054 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5055 (hppa_look_for_stubs_in_section): Do not return false on failure
5056 until rest of code is ready to handle it. Abort for now.

5081 action in case where caller specified no argument relocation.
5082 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5083 right in the original relocation and the stub's relocation.
5085 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5086 unused symbols argument.
5088 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5090 Set reloc->sym_ptr_ptr appropriately.
5091 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5092 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5093 argument. Use the output symbols when canonicalizing the relocs,
5094 creating them if necessary.
5096 * linker.c (_bfd_generic_link_output_symbols): Do not
5097 rebuild/clobber the output symbols if they already exist.
5099 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5101 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5103 * bfd-in2.h: Rebuilt.
5105 * srec.c (hex_value): Always set to a size of 256 bytes.
5106 (srec_init): Cosmetic changes.
5108 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5111 PARAMize and staticize rest of functions. Delete unused
5112 functions. Delete unused/unnecessary arguments to some functions.
5113 Group static vars together. Abort for bad errors until we have
5114 error code propogation working. Work on spacing and indention.
5115 Add FIXMEs for unresolved problems. Use enums rather than
5116 #defines for lots of things. Merge two functions which build
5117 linker stubs into a single function (so they can easily share a
5118 ton of common code).
5120 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5122 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5123 avoid depending upon right shifts of signed numbers, and to
5124 correct handling of src_mask with lower bits zero.
5126 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5127 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

5152 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
5154 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5155 (elf_hppa_tc_make_sections): Likewise.
5156 (elf_hppa_final_processing): Add extern decl.
5158 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5159 comments. PARAMize some static functions. Delete unused functions.
5160 Delete unused/unnecessary arguments to many functions. Group
5161 static vars together. Collapse common case statements together
5162 in many places. Use default case when possible instead of listing
5163 each case separately. Abort for bad errors until we get error
5164 code propogation working. Work on spacing and indention problems.
5165 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5166 COMPLEX relocation support (it's never used anyway).
5167 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5168 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5169 (elf_hppa_tc_make_sections): Likewise.
5171 * format.c (bfd_check_format_matches): Initialize matching_vector
5172 to keep gcc -Wall quiet.

5182 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
5184 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

5205 * elfcode.h (elf_core_file_p): Check for core file e_machine match
5206 like in elf_object_p.

5210 * elfcode.h (alloca): Delete declaration.
5212 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5213 number rather than HP9000S800_ID. Note som.c is careful
5214 to make sure CPU_PA_RISC1_0 is always defined.
5216 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)

6016 use get_value to get the symbol value and check for undefined
6018 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6019 undefined, look it up in the linker hash table.
6021 * aoutx.h (translate_symbol_table): The string index 0 has a

6046 The sparc (and possibly other?) NLM format requires a different
6047 way to write exports, so add a write_export field to the backend
6048 data (and set it to NULL for everything but the sparc).
