5690 (som_is_space, som_is_subspace, som_is_container): New functions.
5691 Use these instead of directly accessing private data.
5692 (som_prep_headers): Allocate space and subspace headers here.
5693 Fill in some fields in the space/subspace headers from the
5695 (som_bfd_copy_private_section_data): Only copy the stuff
5696 that we really need to make objcopy and strip work. Allocate
5697 the copy_data structure for the output bfd before copying.
5699 * som.h (struct som_exec_data): New structure to hold exec
5700 info that must be preserved when running objcopy/strip.
5701 (struct somdata): Add new "exec_data" field and accessor
5702 macro. Add some comments on how the various fields are used.
5703 (som_section_data_struct): Make is_space and is_subspace bitfields.
5704 Delete unused subspace_index. All references now use the
5705 target_index field within the section structure itself.
5707 * som.c (make_unique_section): Delete unused declaration.
5708 (som_bfd_copy_private_bfd_data): New function.
5709 (som_object_setup): Allocate space for and save exec information
5710 that needs to be copied during objcopy/strip.
5711 (som_mkobject): Do not allocate space for a file header here.
5712 It is not used when only reading SOM objects.
5713 (som_prep_headers): Allocate space for and attach a file header
5714 to the output bfd. For executables, use the saved system_id
5715 value rather than trying to guess the right value. Do not abort
5716 wwhen setting file_hdr->entry* for executables.
5717 (som_begin_writing): For executables, set the exec_entry and
5719 (som_copy_private_backend_section_data): Always return a value.
5721 * libhppa.h (PA_PAGESIZE): Define.
5723 * som.c (SOM_ALIGN): Define.
5724 (som_begin_writing): If writing an executable, initialize all
5725 fields in the exec header to zero. Update fields in the exec
5726 header as sizes of loadable subspaces are computed. Carefully
5727 preserve alignments when building executables. Actually write the
5728 exec after all the fields are filled in.
5730 * Better long-filename handling. Reads SOM ABI compliant extended
5731 names, but doesn't quite write compliant extended names yet.
5732 * som.c (som_slurp_extended_name_table): Delete function. The
5733 generic code will handle things correctly.
5734 (som_slurp_armap): Seek to the beginning of the next member.
5735 (normalize): New function.
5736 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5737 name table into account when computing the file offsets in the
5738 SOM dictionary. Make sure to align to an even boundary.
5739 (som_write_armap): Initialize the checksum to zero.
5740 (ar_maxchars): Fix. Opps.
5742 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5744 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5745 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5747 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5749 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5750 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5751 * bfd-in2.h: Regenerated.
5753 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5754 this was also named trad_unix_bfd_copy_private_bfd_data.
5756 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5758 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5759 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5760 returns NULL, it is not an error. It's possible that some of
5761 these checks are not necessary (because the size can never be
5762 zero), but putting in the checks is the conservative thing to do
5763 in light of the fact that some of these malloc calls replaced
5764 unchecked alloca calls, in which a zero argument would work fine.
5766 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5768 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5769 duplicate definition.

5772 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5773 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5774 failure indication, it merely means there are no relocs.
5776 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5777 after NAME, since SunOS /bin/cc can't handle it.
5779 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5781 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5782 From sukes@glue.umd.edu (Tasuki Hirata).
5784 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5786 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5787 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5788 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5790 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5792 * som.c (som_prep_for_fixups): Detect section symbols based
5793 on either the lack of private data or the symbol flags. Do not
5794 munge section symbol names anymore -- they no longer confuse GDB.
5795 (som_begin_writing): Leave space for an exec header if writing
5797 (som_slurp_symbol_table): Recognize both forms of section symbol
5798 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5799 section symbols to be the name of the section they represent.
5800 Debugging symbols begin with "L$0\001", not just "L$".
5802 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5804 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5806 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5807 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5808 and bfd_is_local_label.
5810 * targets.c: Add new entries to the bfd_target structure.
5812 * bfd.c (bfd_copy_private_bfd_data): New definition.

5823 the target vector which all point to bfd_false.
5825 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5826 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5827 Default new vectors for copying private backend data to bfd_true.
5828 Default new vector for determining if a symbol is a local label
5829 to bfd_generic_is_local_label.
5831 * som.c (som_bfd_copy_private_section_data): New function.
5832 (som_bfd_is_local_label): New function.
5833 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5835 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5837 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5839 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5841 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5844 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5845 Indent some of them to GNU standards.
5847 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5848 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5849 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5850 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5851 Update copyright years.
5853 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5855 * som.c (som_prep_for_fixups): A relocation involving the section
5856 symbol for the *ABS* section is really a relocation involving
5858 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5859 undefined symbols. Correctly distinguish between debugger symbols
5860 and section symbols.
5862 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5863 for spaces and subspaces.
5865 * som.c (som_bfd_count_ar_symbols): Fix typo.
5867 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5868 HAS_RELOC based on the object's magic number.
5869 (make_unique_section): Delete function. BFD and its users are
5870 prepared to handle multiple sections with the same name.
5871 (setup_sections): Allocate space on the BFD's obstack to hold
5872 section names. Use bfd_make_setion_anyway rather than the
5873 obsolete make_unique_section.
5874 (som_prep_headers): Choose the correct SOM magic number based
5876 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5891 is always located at the start of the data section to allow
5892 recovery of the dynamic info from a stripped executable.
5893 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5896 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5898 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5899 cruft (like the #pragma alloca for AIX).
5900 In addition to that problem, the C alloca calls xmalloc, which
5901 means checking for being out of memory can't work right. The
5902 following changes remove all uses of alloca from BFD.
5903 * hosts/solaris2.h: Remove alloca cruft.
5904 * som.c: Replace alloca with a fixed size auto array.
5905 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

5909 * linker.c: Replace alloca with obstack_alloc.
5910 * libbfd.h: Rebuilt.
5912 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5914 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5917 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5919 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5920 Elf*_Off typedefs by their expansion, the typedefs have been
5921 removed from include/elf/internal.h.
5922 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5923 SHT_PROGBITS section.
5925 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5927 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5936 TRAD_CORE_STACK_OFFSET.
5937 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5938 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5940 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5942 * som.[ch]: Do not include libhppa.h in som.c, instead include
5945 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5946 include it in elf32-hppa.h.
5948 * som.c (log2): Return -1 on error rather than aborting.
5949 (setup_sections): Bubble up an error from log2.
5951 * Changes to make HP C compiler happy in both traditional
5953 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5955 (bfd_som_set_section_attributes): Use unsigned int rather than
5956 unsigned char to avoid GNU-C extensions.
5957 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5958 or failure rather than aborting on failure.
5960 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5962 (bfd_som_attach_aux_hdr): Add prototype.
5963 (hppa_som-gen_reloc_type): Likewise.

5997 unused symbols argument.
5999 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

6001 Set reloc->sym_ptr_ptr appropriately.
6002 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6003 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6004 argument. Use the output symbols when canonicalizing the relocs,
6005 creating them if necessary.
6007 * linker.c (_bfd_generic_link_output_symbols): Do not
6008 rebuild/clobber the output symbols if they already exist.
6010 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6012 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

6025 error code propogation working. Work on spacing and indention.
6026 Add FIXMEs for unresolved problems. Use enums rather than
6027 #defines for lots of things. Merge two functions which build
6028 linker stubs into a single function (so they can easily share a
6029 ton of common code).
6031 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
6033 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
6034 avoid depending upon right shifts of signed numbers, and to
6035 correct handling of src_mask with lower bits zero.

6065 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
6066 (elf_hppa_tc_make_sections): Likewise.
6067 (elf_hppa_final_processing): Add extern decl.
6069 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
6070 comments. PARAMize some static functions. Delete unused functions.
6071 Delete unused/unnecessary arguments to many functions. Group
6072 static vars together. Collapse common case statements together
6073 in many places. Use default case when possible instead of listing
6074 each case separately. Abort for bad errors until we get error
6075 code propogation working. Work on spacing and indention problems.
6076 Add FIXMEs for some unresolved problems. Delete hopelessly broken
6077 COMPLEX relocation support (it's never used anyway).
6078 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
6079 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
6080 (elf_hppa_tc_make_sections): Likewise.

6121 * elfcode.h (alloca): Delete declaration.
6123 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
6124 number rather than HP9000S800_ID. Note som.c is careful
6125 to make sure CPU_PA_RISC1_0 is always defined.
6127 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
6129 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

6787 (only testing for m68k and vax at the moment); do verify that the
6788 preprocessor didn't trash the arch name inside the string version.

6819 bfd_som_set_subsection_attributes): Change parameters from char
6820 to int. Following a prototype with an old-style function definition

6923 the symbol value and check for undefined symbols.
6924 (get_value): If the symbol is undefined, look it up in the linker
6926 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6927 use get_value to get the symbol value and check for undefined
6929 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6930 undefined, look it up in the linker hash table.
6932 * aoutx.h (translate_symbol_table): The string index 0 has a

6957 The sparc (and possibly other?) NLM format requires a different
6958 way to write exports, so add a write_export field to the backend
6959 data (and set it to NULL for everything but the sparc).

7009 read_dynamic_relocs fields.
7010 * aout-target.h (MY(backend_data)): Initialize
