1063 an empty .plt section.
1064 (elf32_sparc_relocate_section): For a GOT reloc against a global
1065 symbol when no dynamic object was seen, initialize the contents of
1066 the .got section. For a GOT reloc against a local symbol, only
1067 create a R_SPARC_RELATIVE reloc when generating a shared object.
1068 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1069 create a PLT entry as a R_SPARC_WDISP30 reloc.

1086 storage class slightly more verbose. It's not clear how many

4751 Fill in some fields in the space/subspace headers from the
4753 (som_bfd_copy_private_section_data): Only copy the stuff
4754 that we really need to make objcopy and strip work. Allocate

4758 info that must be preserved when running objcopy/strip.

4766 (som_bfd_copy_private_bfd_data): New function.
4767 (som_object_setup): Allocate space for and save exec information
4768 that needs to be copied during objcopy/strip.
4769 (som_mkobject): Do not allocate space for a file header here.
4770 It is not used when only reading SOM objects.
4771 (som_prep_headers): Allocate space for and attach a file header
4772 to the output bfd. For executables, use the saved system_id
4773 value rather than trying to guess the right value. Do not abort
4774 wwhen setting file_hdr->entry* for executables.
4775 (som_begin_writing): For executables, set the exec_entry and
4777 (som_copy_private_backend_section_data): Always return a value.
4779 * libhppa.h (PA_PAGESIZE): Define.
4781 * som.c (SOM_ALIGN): Define.
4782 (som_begin_writing): If writing an executable, initialize all
4783 fields in the exec header to zero. Update fields in the exec
4784 header as sizes of loadable subspaces are computed. Carefully
4785 preserve alignments when building executables. Actually write the
4786 exec after all the fields are filled in.
4788 * Better long-filename handling. Reads SOM ABI compliant extended
4789 names, but doesn't quite write compliant extended names yet.
4790 * som.c (som_slurp_extended_name_table): Delete function. The
4791 generic code will handle things correctly.
4792 (som_slurp_armap): Seek to the beginning of the next member.
4793 (normalize): New function.
4794 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4795 name table into account when computing the file offsets in the
4796 SOM dictionary. Make sure to align to an even boundary.
4797 (som_write_armap): Initialize the checksum to zero.
4798 (ar_maxchars): Fix. Opps.
4800 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4802 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4803 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4805 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4807 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4808 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4809 * bfd-in2.h: Regenerated.
4811 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4812 this was also named trad_unix_bfd_copy_private_bfd_data.
4814 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4816 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4817 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4818 returns NULL, it is not an error. It's possible that some of
4819 these checks are not necessary (because the size can never be
4820 zero), but putting in the checks is the conservative thing to do
4821 in light of the fact that some of these malloc calls replaced
4822 unchecked alloca calls, in which a zero argument would work fine.
4824 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4826 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4827 duplicate definition.
4828 (osf_core_bfd_is_local_label): Define.
4830 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4831 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4832 failure indication, it merely means there are no relocs.
4834 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4835 after NAME, since SunOS /bin/cc can't handle it.
4837 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4839 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4840 From sukes@glue.umd.edu (Tasuki Hirata).
4842 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4844 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4845 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4846 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4848 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4850 * som.c (som_prep_for_fixups): Detect section symbols based
4851 on either the lack of private data or the symbol flags. Do not
4852 munge section symbol names anymore -- they no longer confuse GDB.
4853 (som_begin_writing): Leave space for an exec header if writing
4855 (som_slurp_symbol_table): Recognize both forms of section symbol
4856 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4857 section symbols to be the name of the section they represent.
4858 Debugging symbols begin with "L$0\001", not just "L$".
4860 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4862 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.

4865 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4866 and bfd_is_local_label.
4868 * targets.c: Add new entries to the bfd_target structure.

4881 the target vector which all point to bfd_false.
4883 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4884 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4885 Default new vectors for copying private backend data to bfd_true.
4886 Default new vector for determining if a symbol is a local label
4887 to bfd_generic_is_local_label.
4889 * som.c (som_bfd_copy_private_section_data): New function.
4890 (som_bfd_is_local_label): New function.
4891 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4893 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4895 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4897 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4899 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4902 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4903 Indent some of them to GNU standards.
4905 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4906 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4907 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4908 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4909 Update copyright years.
4911 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4913 * som.c (som_prep_for_fixups): A relocation involving the section
4914 symbol for the *ABS* section is really a relocation involving
4916 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4917 undefined symbols. Correctly distinguish between debugger symbols
4918 and section symbols.
4920 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4921 for spaces and subspaces.
4923 * som.c (som_bfd_count_ar_symbols): Fix typo.
4925 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4926 HAS_RELOC based on the object's magic number.
4927 (make_unique_section): Delete function. BFD and its users are
4928 prepared to handle multiple sections with the same name.
4929 (setup_sections): Allocate space on the BFD's obstack to hold
4930 section names. Use bfd_make_setion_anyway rather than the
4931 obsolete make_unique_section.
4932 (som_prep_headers): Choose the correct SOM magic number based
4934 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4954 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4956 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4957 cruft (like the #pragma alloca for AIX).
4958 In addition to that problem, the C alloca calls xmalloc, which
4959 means checking for being out of memory can't work right. The
4960 following changes remove all uses of alloca from BFD.
4961 * hosts/solaris2.h: Remove alloca cruft.
4962 * som.c: Replace alloca with a fixed size auto array.

4967 * linker.c: Replace alloca with obstack_alloc.
4968 * libbfd.h: Rebuilt.
4970 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4972 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4975 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4977 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4978 Elf*_Off typedefs by their expansion, the typedefs have been
4979 removed from include/elf/internal.h.
4980 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4981 SHT_PROGBITS section.
4983 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4985 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4994 TRAD_CORE_STACK_OFFSET.
4995 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4996 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4998 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5000 * som.[ch]: Do not include libhppa.h in som.c, instead include
5003 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5004 include it in elf32-hppa.h.
5006 * som.c (log2): Return -1 on error rather than aborting.
5007 (setup_sections): Bubble up an error from log2.
5009 * Changes to make HP C compiler happy in both traditional
5011 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5013 (bfd_som_set_section_attributes): Use unsigned int rather than
5014 unsigned char to avoid GNU-C extensions.
5015 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5016 or failure rather than aborting on failure.
5018 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5020 (bfd_som_attach_aux_hdr): Add prototype.
5021 (hppa_som-gen_reloc_type): Likewise.

5055 unused symbols argument.
5057 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5059 Set reloc->sym_ptr_ptr appropriately.
5060 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5061 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5062 argument. Use the output symbols when canonicalizing the relocs,
5063 creating them if necessary.
5065 * linker.c (_bfd_generic_link_output_symbols): Do not
5066 rebuild/clobber the output symbols if they already exist.
5068 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5070 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5080 PARAMize and staticize rest of functions. Delete unused
5081 functions. Delete unused/unnecessary arguments to some functions.

5083 error code propogation working. Work on spacing and indention.
5084 Add FIXMEs for unresolved problems. Use enums rather than
5085 #defines for lots of things. Merge two functions which build
5086 linker stubs into a single function (so they can easily share a
5087 ton of common code).
5089 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5091 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5092 avoid depending upon right shifts of signed numbers, and to
5093 correct handling of src_mask with lower bits zero.

5125 (elf_hppa_final_processing): Add extern decl.
5127 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5128 comments. PARAMize some static functions. Delete unused functions.

5132 each case separately. Abort for bad errors until we get error
5133 code propogation working. Work on spacing and indention problems.

5135 COMPLEX relocation support (it's never used anyway).
5136 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5137 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5138 (elf_hppa_tc_make_sections): Likewise.

5179 * elfcode.h (alloca): Delete declaration.
5181 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5182 number rather than HP9000S800_ID. Note som.c is careful
5183 to make sure CPU_PA_RISC1_0 is always defined.
5185 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5187 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5204 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
5205 operation to avoid OSF 1.3 cc bug.
5206 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
5207 and bss_size bfd_size_type instead of unsigned long. Make
5208 text_start and data_start bfd_vma instead of unsigned long.

5877 bfd_som_set_subsection_attributes): Change parameters from char
5878 to int. Following a prototype with an old-style function definition

5985 use get_value to get the symbol value and check for undefined
5987 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5988 undefined, look it up in the linker hash table.
5990 * aoutx.h (translate_symbol_table): The string index 0 has a

6015 The sparc (and possibly other?) NLM format requires a different
6016 way to write exports, so add a write_export field to the backend
6017 data (and set it to NULL for everything but the sparc).

6067 read_dynamic_relocs fields.
6068 * aout-target.h (MY(backend_data)): Initialize
