5687 (som_is_space, som_is_subspace, som_is_container): New functions.
5688 Use these instead of directly accessing private data.
5689 (som_prep_headers): Allocate space and subspace headers here.
5690 Fill in some fields in the space/subspace headers from the
5692 (som_bfd_copy_private_section_data): Only copy the stuff
5693 that we really need to make objcopy and strip work. Allocate
5694 the copy_data structure for the output bfd before copying.
5696 * som.h (struct som_exec_data): New structure to hold exec
5697 info that must be preserved when running objcopy/strip.
5698 (struct somdata): Add new "exec_data" field and accessor
5699 macro. Add some comments on how the various fields are used.
5700 (som_section_data_struct): Make is_space and is_subspace bitfields.
5701 Delete unused subspace_index. All references now use the
5702 target_index field within the section structure itself.
5704 * som.c (make_unique_section): Delete unused declaration.
5705 (som_bfd_copy_private_bfd_data): New function.
5706 (som_object_setup): Allocate space for and save exec information
5707 that needs to be copied during objcopy/strip.
5708 (som_mkobject): Do not allocate space for a file header here.
5709 It is not used when only reading SOM objects.
5710 (som_prep_headers): Allocate space for and attach a file header
5711 to the output bfd. For executables, use the saved system_id
5712 value rather than trying to guess the right value. Do not abort
5713 wwhen setting file_hdr->entry* for executables.
5714 (som_begin_writing): For executables, set the exec_entry and
5716 (som_copy_private_backend_section_data): Always return a value.
5718 * libhppa.h (PA_PAGESIZE): Define.
5720 * som.c (SOM_ALIGN): Define.
5721 (som_begin_writing): If writing an executable, initialize all
5722 fields in the exec header to zero. Update fields in the exec
5723 header as sizes of loadable subspaces are computed. Carefully
5724 preserve alignments when building executables. Actually write the
5725 exec after all the fields are filled in.
5727 * Better long-filename handling. Reads SOM ABI compliant extended
5728 names, but doesn't quite write compliant extended names yet.
5729 * som.c (som_slurp_extended_name_table): Delete function. The
5730 generic code will handle things correctly.
5731 (som_slurp_armap): Seek to the beginning of the next member.
5732 (normalize): New function.
5733 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5734 name table into account when computing the file offsets in the
5735 SOM dictionary. Make sure to align to an even boundary.
5736 (som_write_armap): Initialize the checksum to zero.
5737 (ar_maxchars): Fix. Opps.
5739 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5741 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5742 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

5746 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5747 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5748 * bfd-in2.h: Regenerated.
5750 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5751 this was also named trad_unix_bfd_copy_private_bfd_data.
5753 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5755 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5756 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5757 returns NULL, it is not an error. It's possible that some of
5758 these checks are not necessary (because the size can never be
5759 zero), but putting in the checks is the conservative thing to do
5760 in light of the fact that some of these malloc calls replaced
5761 unchecked alloca calls, in which a zero argument would work fine.
5763 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5765 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5766 duplicate definition.

5769 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5770 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5771 failure indication, it merely means there are no relocs.
5773 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5774 after NAME, since SunOS /bin/cc can't handle it.
5776 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5778 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5779 From sukes@glue.umd.edu (Tasuki Hirata).
5781 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5783 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5784 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5785 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5787 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5789 * som.c (som_prep_for_fixups): Detect section symbols based
5790 on either the lack of private data or the symbol flags. Do not
5791 munge section symbol names anymore -- they no longer confuse GDB.
5792 (som_begin_writing): Leave space for an exec header if writing
5794 (som_slurp_symbol_table): Recognize both forms of section symbol
5795 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5796 section symbols to be the name of the section they represent.
5797 Debugging symbols begin with "L$0\001", not just "L$".
5799 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5801 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5803 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5804 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5805 and bfd_is_local_label.
5807 * targets.c: Add new entries to the bfd_target structure.
5809 * bfd.c (bfd_copy_private_bfd_data): New definition.

5820 the target vector which all point to bfd_false.
5822 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5823 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5824 Default new vectors for copying private backend data to bfd_true.
5825 Default new vector for determining if a symbol is a local label
5826 to bfd_generic_is_local_label.
5828 * som.c (som_bfd_copy_private_section_data): New function.
5829 (som_bfd_is_local_label): New function.
5830 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5832 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5834 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5836 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5838 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5841 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5842 Indent some of them to GNU standards.
5844 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5845 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5846 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5847 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5848 Update copyright years.
5850 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5852 * som.c (som_prep_for_fixups): A relocation involving the section
5853 symbol for the *ABS* section is really a relocation involving
5855 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5856 undefined symbols. Correctly distinguish between debugger symbols
5857 and section symbols.
5859 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5860 for spaces and subspaces.
5862 * som.c (som_bfd_count_ar_symbols): Fix typo.
5864 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5865 HAS_RELOC based on the object's magic number.
5866 (make_unique_section): Delete function. BFD and its users are
5867 prepared to handle multiple sections with the same name.
5868 (setup_sections): Allocate space on the BFD's obstack to hold
5869 section names. Use bfd_make_setion_anyway rather than the
5870 obsolete make_unique_section.
5871 (som_prep_headers): Choose the correct SOM magic number based
5873 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5893 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5895 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5896 cruft (like the #pragma alloca for AIX).
5897 In addition to that problem, the C alloca calls xmalloc, which
5898 means checking for being out of memory can't work right. The
5899 following changes remove all uses of alloca from BFD.
5900 * hosts/solaris2.h: Remove alloca cruft.
5901 * som.c: Replace alloca with a fixed size auto array.

5906 * linker.c: Replace alloca with obstack_alloc.
5907 * libbfd.h: Rebuilt.
5909 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5911 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5914 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5916 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5917 Elf*_Off typedefs by their expansion, the typedefs have been
5918 removed from include/elf/internal.h.
5919 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5920 SHT_PROGBITS section.
5922 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5924 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5933 TRAD_CORE_STACK_OFFSET.
5934 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5935 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5937 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5939 * som.[ch]: Do not include libhppa.h in som.c, instead include
5942 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5943 include it in elf32-hppa.h.
5945 * som.c (log2): Return -1 on error rather than aborting.
5946 (setup_sections): Bubble up an error from log2.
5948 * Changes to make HP C compiler happy in both traditional
5950 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5952 (bfd_som_set_section_attributes): Use unsigned int rather than
5953 unsigned char to avoid GNU-C extensions.
5954 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5955 or failure rather than aborting on failure.
5957 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5959 (bfd_som_attach_aux_hdr): Add prototype.
5960 (hppa_som-gen_reloc_type): Likewise.

5994 unused symbols argument.
5996 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5998 Set reloc->sym_ptr_ptr appropriately.
5999 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6000 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6001 argument. Use the output symbols when canonicalizing the relocs,
6002 creating them if necessary.
6004 * linker.c (_bfd_generic_link_output_symbols): Do not
6005 rebuild/clobber the output symbols if they already exist.
6007 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6009 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

6022 error code propogation working. Work on spacing and indention.
6023 Add FIXMEs for unresolved problems. Use enums rather than
6024 #defines for lots of things. Merge two functions which build
6025 linker stubs into a single function (so they can easily share a
6026 ton of common code).
6028 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
6030 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
6031 avoid depending upon right shifts of signed numbers, and to
6032 correct handling of src_mask with lower bits zero.

6063 (elf_hppa_tc_make_sections): Likewise.
6064 (elf_hppa_final_processing): Add extern decl.
6066 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
6067 comments. PARAMize some static functions. Delete unused functions.
6068 Delete unused/unnecessary arguments to many functions. Group
6069 static vars together. Collapse common case statements together
6070 in many places. Use default case when possible instead of listing
6071 each case separately. Abort for bad errors until we get error
6072 code propogation working. Work on spacing and indention problems.
6073 Add FIXMEs for some unresolved problems. Delete hopelessly broken
6074 COMPLEX relocation support (it's never used anyway).
6075 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
6076 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
6077 (elf_hppa_tc_make_sections): Likewise.

6118 * elfcode.h (alloca): Delete declaration.
6120 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
6121 number rather than HP9000S800_ID. Note som.c is careful
6122 to make sure CPU_PA_RISC1_0 is always defined.
6124 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
6126 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

6138 * som.c (som_bfd_count_ar_symbols): Use a pointer and alloca
6139 rather than an array of variable size.

6143 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
6144 operation to avoid OSF 1.3 cc bug.

6664 * srec.c (srec_write_record): Put CONST keyword for "src" before
6665 "unsigned", some compilers don't like it after "unsigned".
6666 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

6816 bfd_som_set_subsection_attributes): Change parameters from char
6817 to int. Following a prototype with an old-style function definition

6921 (get_value): If the symbol is undefined, look it up in the linker
6923 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6924 use get_value to get the symbol value and check for undefined
6926 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6927 undefined, look it up in the linker hash table.
6929 * aoutx.h (translate_symbol_table): The string index 0 has a

6954 The sparc (and possibly other?) NLM format requires a different
6955 way to write exports, so add a write_export field to the backend
6956 data (and set it to NULL for everything but the sparc).

7006 read_dynamic_relocs fields.
7007 * aout-target.h (MY(backend_data)): Initialize
