1068 an empty .plt section.
1069 (elf32_sparc_relocate_section): For a GOT reloc against a global
1070 symbol when no dynamic object was seen, initialize the contents of
1071 the .got section. For a GOT reloc against a local symbol, only
1072 create a R_SPARC_RELATIVE reloc when generating a shared object.
1073 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1074 create a PLT entry as a R_SPARC_WDISP30 reloc.

4750 some references changed. Allocate a copyable data stucture if
4751 none exists. Store info into the copyable data structure.

4756 Fill in some fields in the space/subspace headers from the
4758 (som_bfd_copy_private_section_data): Only copy the stuff
4759 that we really need to make objcopy and strip work. Allocate
4760 the copy_data structure for the output bfd before copying.

4763 info that must be preserved when running objcopy/strip.
4764 (struct somdata): Add new "exec_data" field and accessor
4765 macro. Add some comments on how the various fields are used.
4766 (som_section_data_struct): Make is_space and is_subspace bitfields.
4767 Delete unused subspace_index. All references now use the
4768 target_index field within the section structure itself.
4770 * som.c (make_unique_section): Delete unused declaration.
4771 (som_bfd_copy_private_bfd_data): New function.
4772 (som_object_setup): Allocate space for and save exec information
4773 that needs to be copied during objcopy/strip.
4774 (som_mkobject): Do not allocate space for a file header here.
4775 It is not used when only reading SOM objects.
4776 (som_prep_headers): Allocate space for and attach a file header
4777 to the output bfd. For executables, use the saved system_id
4778 value rather than trying to guess the right value. Do not abort
4779 wwhen setting file_hdr->entry* for executables.
4780 (som_begin_writing): For executables, set the exec_entry and
4782 (som_copy_private_backend_section_data): Always return a value.
4784 * libhppa.h (PA_PAGESIZE): Define.
4786 * som.c (SOM_ALIGN): Define.
4787 (som_begin_writing): If writing an executable, initialize all
4788 fields in the exec header to zero. Update fields in the exec
4789 header as sizes of loadable subspaces are computed. Carefully
4790 preserve alignments when building executables. Actually write the
4791 exec after all the fields are filled in.
4793 * Better long-filename handling. Reads SOM ABI compliant extended
4794 names, but doesn't quite write compliant extended names yet.
4795 * som.c (som_slurp_extended_name_table): Delete function. The
4796 generic code will handle things correctly.
4797 (som_slurp_armap): Seek to the beginning of the next member.
4798 (normalize): New function.
4799 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4800 name table into account when computing the file offsets in the
4801 SOM dictionary. Make sure to align to an even boundary.
4802 (som_write_armap): Initialize the checksum to zero.
4803 (ar_maxchars): Fix. Opps.
4805 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4807 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4808 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4810 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4812 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4813 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4814 * bfd-in2.h: Regenerated.
4816 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4817 this was also named trad_unix_bfd_copy_private_bfd_data.
4819 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4821 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4822 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4823 returns NULL, it is not an error. It's possible that some of
4824 these checks are not necessary (because the size can never be
4825 zero), but putting in the checks is the conservative thing to do
4826 in light of the fact that some of these malloc calls replaced
4827 unchecked alloca calls, in which a zero argument would work fine.
4829 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4831 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4832 duplicate definition.

4835 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4836 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4837 failure indication, it merely means there are no relocs.
4839 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4840 after NAME, since SunOS /bin/cc can't handle it.
4842 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4844 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4845 From sukes@glue.umd.edu (Tasuki Hirata).
4847 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4849 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4850 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4851 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4853 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4855 * som.c (som_prep_for_fixups): Detect section symbols based
4856 on either the lack of private data or the symbol flags. Do not
4857 munge section symbol names anymore -- they no longer confuse GDB.
4858 (som_begin_writing): Leave space for an exec header if writing
4860 (som_slurp_symbol_table): Recognize both forms of section symbol
4861 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4862 section symbols to be the name of the section they represent.
4863 Debugging symbols begin with "L$0\001", not just "L$".
4865 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4867 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4869 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4870 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4871 and bfd_is_local_label.
4873 * targets.c: Add new entries to the bfd_target structure.

4886 the target vector which all point to bfd_false.
4888 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4889 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4890 Default new vectors for copying private backend data to bfd_true.
4891 Default new vector for determining if a symbol is a local label
4892 to bfd_generic_is_local_label.
4894 * som.c (som_bfd_copy_private_section_data): New function.
4895 (som_bfd_is_local_label): New function.
4896 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4898 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4900 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4902 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4904 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4907 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4908 Indent some of them to GNU standards.
4910 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4911 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4912 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4913 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4914 Update copyright years.
4916 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4918 * som.c (som_prep_for_fixups): A relocation involving the section
4919 symbol for the *ABS* section is really a relocation involving
4921 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4922 undefined symbols. Correctly distinguish between debugger symbols
4923 and section symbols.
4925 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4926 for spaces and subspaces.
4928 * som.c (som_bfd_count_ar_symbols): Fix typo.
4930 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4931 HAS_RELOC based on the object's magic number.
4932 (make_unique_section): Delete function. BFD and its users are
4933 prepared to handle multiple sections with the same name.
4934 (setup_sections): Allocate space on the BFD's obstack to hold
4935 section names. Use bfd_make_setion_anyway rather than the
4936 obsolete make_unique_section.
4937 (som_prep_headers): Choose the correct SOM magic number based
4939 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4959 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4961 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4962 cruft (like the #pragma alloca for AIX).
4963 In addition to that problem, the C alloca calls xmalloc, which
4964 means checking for being out of memory can't work right. The
4965 following changes remove all uses of alloca from BFD.
4966 * hosts/solaris2.h: Remove alloca cruft.
4967 * som.c: Replace alloca with a fixed size auto array.

4972 * linker.c: Replace alloca with obstack_alloc.
4973 * libbfd.h: Rebuilt.
4975 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4977 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4980 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4982 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4983 Elf*_Off typedefs by their expansion, the typedefs have been
4984 removed from include/elf/internal.h.
4985 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4986 SHT_PROGBITS section.
4988 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4999 TRAD_CORE_STACK_OFFSET.
5000 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5001 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5003 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5005 * som.[ch]: Do not include libhppa.h in som.c, instead include
5008 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5009 include it in elf32-hppa.h.
5011 * som.c (log2): Return -1 on error rather than aborting.
5012 (setup_sections): Bubble up an error from log2.
5014 * Changes to make HP C compiler happy in both traditional
5016 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5018 (bfd_som_set_section_attributes): Use unsigned int rather than
5019 unsigned char to avoid GNU-C extensions.
5020 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5021 or failure rather than aborting on failure.
5023 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5025 (bfd_som_attach_aux_hdr): Add prototype.
5026 (hppa_som-gen_reloc_type): Likewise.

5060 unused symbols argument.
5062 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5064 Set reloc->sym_ptr_ptr appropriately.
5065 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5066 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5067 argument. Use the output symbols when canonicalizing the relocs,
5068 creating them if necessary.
5070 * linker.c (_bfd_generic_link_output_symbols): Do not
5071 rebuild/clobber the output symbols if they already exist.
5073 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)

5085 PARAMize and staticize rest of functions. Delete unused
5086 functions. Delete unused/unnecessary arguments to some functions.

5088 error code propogation working. Work on spacing and indention.
5089 Add FIXMEs for unresolved problems. Use enums rather than
5090 #defines for lots of things. Merge two functions which build
5091 linker stubs into a single function (so they can easily share a
5092 ton of common code).
5094 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5096 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5097 avoid depending upon right shifts of signed numbers, and to
5098 correct handling of src_mask with lower bits zero.

5130 (elf_hppa_final_processing): Add extern decl.
5132 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5133 comments. PARAMize some static functions. Delete unused functions.

5135 static vars together. Collapse common case statements together
5136 in many places. Use default case when possible instead of listing
5137 each case separately. Abort for bad errors until we get error
5138 code propogation working. Work on spacing and indention problems.
5139 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5140 COMPLEX relocation support (it's never used anyway).
5141 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5142 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5143 (elf_hppa_tc_make_sections): Likewise.

5184 * elfcode.h (alloca): Delete declaration.
5186 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5187 number rather than HP9000S800_ID. Note som.c is careful
5188 to make sure CPU_PA_RISC1_0 is always defined.
5190 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5192 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5209 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
5210 operation to avoid OSF 1.3 cc bug.
5211 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
5212 and bss_size bfd_size_type instead of unsigned long. Make
5213 text_start and data_start bfd_vma instead of unsigned long.

5882 bfd_som_set_subsection_attributes): Change parameters from char
5883 to int. Following a prototype with an old-style function definition

5990 use get_value to get the symbol value and check for undefined
5992 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5993 undefined, look it up in the linker hash table.
5995 * aoutx.h (translate_symbol_table): The string index 0 has a

6020 The sparc (and possibly other?) NLM format requires a different
6021 way to write exports, so add a write_export field to the backend
6022 data (and set it to NULL for everything but the sparc).
