2027 an empty .plt section.
2028 (elf32_sparc_relocate_section): For a GOT reloc against a global
2029 symbol when no dynamic object was seen, initialize the contents of

5690 * cisco-core.c: New file.
5691 * Makefile.in: Change accordingly.
5692 * configure.in: Recognize cisco_core_vec.
5693 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5694 * targets.c: Add cisco_core_vec.
5695 * bfd-in2.h: Rebuilt.
5697 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5699 * som.h (som_copyable_section_data_struct): New structure
5700 containing all the private section information which needs
5701 to be copied from input section to output section during
5703 (som_section_data_struct): Remove several fields now in
5704 som_copyable_section_data_struct. Make the space and
5705 subspace dictionaries be pointers (to save space when
5706 only reading objects).
5708 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5709 some references changed. Allocate a copyable data stucture if
5710 none exists. Store info into the copyable data structure.
5711 (bfd_som_set_subsection_attributes): Likewise.
5712 (som_is_space, som_is_subspace, som_is_container): New functions.
5713 Use these instead of directly accessing private data.
5714 (som_prep_headers): Allocate space and subspace headers here.
5715 Fill in some fields in the space/subspace headers from the
5717 (som_bfd_copy_private_section_data): Only copy the stuff
5718 that we really need to make objcopy and strip work. Allocate
5719 the copy_data structure for the output bfd before copying.
5721 * som.h (struct som_exec_data): New structure to hold exec
5722 info that must be preserved when running objcopy/strip.
5723 (struct somdata): Add new "exec_data" field and accessor
5724 macro. Add some comments on how the various fields are used.
5725 (som_section_data_struct): Make is_space and is_subspace bitfields.
5726 Delete unused subspace_index. All references now use the
5727 target_index field within the section structure itself.
5729 * som.c (make_unique_section): Delete unused declaration.
5730 (som_bfd_copy_private_bfd_data): New function.
5731 (som_object_setup): Allocate space for and save exec information
5732 that needs to be copied during objcopy/strip.
5733 (som_mkobject): Do not allocate space for a file header here.
5734 It is not used when only reading SOM objects.
5735 (som_prep_headers): Allocate space for and attach a file header
5736 to the output bfd. For executables, use the saved system_id
5737 value rather than trying to guess the right value. Do not abort
5738 wwhen setting file_hdr->entry* for executables.
5739 (som_begin_writing): For executables, set the exec_entry and
5741 (som_copy_private_backend_section_data): Always return a value.
5743 * libhppa.h (PA_PAGESIZE): Define.
5745 * som.c (SOM_ALIGN): Define.
5746 (som_begin_writing): If writing an executable, initialize all
5747 fields in the exec header to zero. Update fields in the exec
5748 header as sizes of loadable subspaces are computed. Carefully
5749 preserve alignments when building executables. Actually write the
5750 exec after all the fields are filled in.
5752 * Better long-filename handling. Reads SOM ABI compliant extended
5753 names, but doesn't quite write compliant extended names yet.
5754 * som.c (som_slurp_extended_name_table): Delete function. The
5755 generic code will handle things correctly.
5756 (som_slurp_armap): Seek to the beginning of the next member.
5757 (normalize): New function.
5758 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5759 name table into account when computing the file offsets in the
5760 SOM dictionary. Make sure to align to an even boundary.
5761 (som_write_armap): Initialize the checksum to zero.
5762 (ar_maxchars): Fix. Opps.
5764 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5766 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5767 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5769 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5771 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5772 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5773 * bfd-in2.h: Regenerated.
5775 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5776 this was also named trad_unix_bfd_copy_private_bfd_data.
5778 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5780 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5781 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5782 returns NULL, it is not an error. It's possible that some of
5783 these checks are not necessary (because the size can never be
5784 zero), but putting in the checks is the conservative thing to do
5785 in light of the fact that some of these malloc calls replaced
5786 unchecked alloca calls, in which a zero argument would work fine.
5788 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5790 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5791 duplicate definition.
5792 (osf_core_bfd_is_local_label): Define.
5794 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5795 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5796 failure indication, it merely means there are no relocs.
5798 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5799 after NAME, since SunOS /bin/cc can't handle it.
5801 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5803 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5804 From sukes@glue.umd.edu (Tasuki Hirata).
5806 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5808 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5809 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5810 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5812 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5814 * som.c (som_prep_for_fixups): Detect section symbols based
5815 on either the lack of private data or the symbol flags. Do not
5816 munge section symbol names anymore -- they no longer confuse GDB.
5817 (som_begin_writing): Leave space for an exec header if writing
5819 (som_slurp_symbol_table): Recognize both forms of section symbol
5820 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5821 section symbols to be the name of the section they represent.
5822 Debugging symbols begin with "L$0\001", not just "L$".
5824 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5826 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5828 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5829 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5830 and bfd_is_local_label.
5832 * targets.c: Add new entries to the bfd_target structure.
5834 * bfd.c (bfd_copy_private_bfd_data): New definition.
5836 * section.c (bfd_copy_private_section_data): New definition.

5840 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5842 * libbfd.c (bfd_generic_is_local_label): New function.
5844 * *-core.c: Provide default definitions for new functions in
5845 the target vector which all point to bfd_false.
5847 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5848 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5849 Default new vectors for copying private backend data to bfd_true.
5850 Default new vector for determining if a symbol is a local label
5851 to bfd_generic_is_local_label.
5853 * som.c (som_bfd_copy_private_section_data): New function.
5854 (som_bfd_is_local_label): New function.
5855 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5857 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5859 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5861 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5863 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5866 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5867 Indent some of them to GNU standards.
5869 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5870 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5871 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5872 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5873 Update copyright years.
5875 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5877 * som.c (som_prep_for_fixups): A relocation involving the section
5878 symbol for the *ABS* section is really a relocation involving
5880 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5881 undefined symbols. Correctly distinguish between debugger symbols
5882 and section symbols.
5884 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5885 for spaces and subspaces.
5887 * som.c (som_bfd_count_ar_symbols): Fix typo.
5889 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5890 HAS_RELOC based on the object's magic number.
5891 (make_unique_section): Delete function. BFD and its users are
5892 prepared to handle multiple sections with the same name.
5893 (setup_sections): Allocate space on the BFD's obstack to hold
5894 section names. Use bfd_make_setion_anyway rather than the
5895 obsolete make_unique_section.
5896 (som_prep_headers): Choose the correct SOM magic number based
5898 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5912 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5913 is always located at the start of the data section to allow
5914 recovery of the dynamic info from a stripped executable.

5918 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5920 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5921 cruft (like the #pragma alloca for AIX).
5922 In addition to that problem, the C alloca calls xmalloc, which
5923 means checking for being out of memory can't work right. The
5924 following changes remove all uses of alloca from BFD.
5925 * hosts/solaris2.h: Remove alloca cruft.
5926 * som.c: Replace alloca with a fixed size auto array.
5927 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

5929 sunos.c: Replace alloca with malloc and appropriate error checking and
5931 * linker.c: Replace alloca with obstack_alloc.
5932 * libbfd.h: Rebuilt.
5934 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5936 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5939 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5941 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5942 Elf*_Off typedefs by their expansion, the typedefs have been
5943 removed from include/elf/internal.h.
5944 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5945 SHT_PROGBITS section.
5947 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5949 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5955 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5956 return from bfd_seek indicates an error.
5957 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5958 TRAD_CORE_STACK_OFFSET.
5959 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5960 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5962 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5964 * som.[ch]: Do not include libhppa.h in som.c, instead include
5967 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5968 include it in elf32-hppa.h.
5970 * som.c (log2): Return -1 on error rather than aborting.
5971 (setup_sections): Bubble up an error from log2.
5973 * Changes to make HP C compiler happy in both traditional
5975 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5977 (bfd_som_set_section_attributes): Use unsigned int rather than
5978 unsigned char to avoid GNU-C extensions.
5979 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5980 or failure rather than aborting on failure.
5982 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5984 (bfd_som_attach_aux_hdr): Add prototype.
5985 (hppa_som-gen_reloc_type): Likewise.
5987 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5988 (hppa_look_for_stubs_in_section): Do not return false on failure
5989 until rest of code is ready to handle it. Abort for now.

6015 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6016 right in the original relocation and the stub's relocation.

6019 unused symbols argument.
6021 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

6023 Set reloc->sym_ptr_ptr appropriately.
6024 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6025 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6026 argument. Use the output symbols when canonicalizing the relocs,
6027 creating them if necessary.
6029 * linker.c (_bfd_generic_link_output_symbols): Do not
6030 rebuild/clobber the output symbols if they already exist.
6032 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6034 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

6036 * bfd-in2.h: Rebuilt.
6038 * srec.c (hex_value): Always set to a size of 256 bytes.
6039 (srec_init): Cosmetic changes.
6041 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6044 PARAMize and staticize rest of functions. Delete unused
6045 functions. Delete unused/unnecessary arguments to some functions.
6046 Group static vars together. Abort for bad errors until we have
6047 error code propogation working. Work on spacing and indention.
6048 Add FIXMEs for unresolved problems. Use enums rather than
6049 #defines for lots of things. Merge two functions which build
6050 linker stubs into a single function (so they can easily share a
6051 ton of common code).
6053 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
6055 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
6056 avoid depending upon right shifts of signed numbers, and to
6057 correct handling of src_mask with lower bits zero.
6059 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

6087 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
6088 (elf_hppa_tc_make_sections): Likewise.
6089 (elf_hppa_final_processing): Add extern decl.
6091 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
6092 comments. PARAMize some static functions. Delete unused functions.
6093 Delete unused/unnecessary arguments to many functions. Group
6094 static vars together. Collapse common case statements together
6095 in many places. Use default case when possible instead of listing
6096 each case separately. Abort for bad errors until we get error
6097 code propogation working. Work on spacing and indention problems.
6098 Add FIXMEs for some unresolved problems. Delete hopelessly broken
6099 COMPLEX relocation support (it's never used anyway).
6100 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
6101 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
6102 (elf_hppa_tc_make_sections): Likewise.

6115 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
6117 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

6143 * elfcode.h (alloca): Delete declaration.
6145 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

6949 use get_value to get the symbol value and check for undefined
6951 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6952 undefined, look it up in the linker hash table.
6954 * aoutx.h (translate_symbol_table): The string index 0 has a

6979 The sparc (and possibly other?) NLM format requires a different
6980 way to write exports, so add a write_export field to the backend
6981 data (and set it to NULL for everything but the sparc).
