1046 .rela.got section to zero. Strip empty reloc sections, and strip
1047 an empty .plt section.
1048 (elf32_sparc_relocate_section): For a GOT reloc against a global
1049 symbol when no dynamic object was seen, initialize the contents of
1050 the .got section. For a GOT reloc against a local symbol, only
1051 create a R_SPARC_RELATIVE reloc when generating a shared object.
1052 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1053 create a PLT entry as a R_SPARC_WDISP30 reloc.

1070 storage class slightly more verbose. It's not clear how many
1071 characters I can justify using up, but before this change they

4735 Fill in some fields in the space/subspace headers from the
4737 (som_bfd_copy_private_section_data): Only copy the stuff
4738 that we really need to make objcopy and strip work. Allocate
4739 the copy_data structure for the output bfd before copying.

4742 info that must be preserved when running objcopy/strip.

4744 macro. Add some comments on how the various fields are used.
4745 (som_section_data_struct): Make is_space and is_subspace bitfields.

4754 It is not used when only reading SOM objects.
4755 (som_prep_headers): Allocate space for and attach a file header
4756 to the output bfd. For executables, use the saved system_id
4757 value rather than trying to guess the right value. Do not abort
4758 wwhen setting file_hdr->entry* for executables.
4759 (som_begin_writing): For executables, set the exec_entry and
4761 (som_copy_private_backend_section_data): Always return a value.
4763 * libhppa.h (PA_PAGESIZE): Define.
4765 * som.c (SOM_ALIGN): Define.
4766 (som_begin_writing): If writing an executable, initialize all
4767 fields in the exec header to zero. Update fields in the exec
4768 header as sizes of loadable subspaces are computed. Carefully
4769 preserve alignments when building executables. Actually write the
4770 exec after all the fields are filled in.
4772 * Better long-filename handling. Reads SOM ABI compliant extended
4773 names, but doesn't quite write compliant extended names yet.
4774 * som.c (som_slurp_extended_name_table): Delete function. The
4775 generic code will handle things correctly.
4776 (som_slurp_armap): Seek to the beginning of the next member.
4777 (normalize): New function.
4778 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4779 name table into account when computing the file offsets in the
4780 SOM dictionary. Make sure to align to an even boundary.
4781 (som_write_armap): Initialize the checksum to zero.
4782 (ar_maxchars): Fix. Opps.
4784 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4786 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4787 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4789 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4791 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4792 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4793 * bfd-in2.h: Regenerated.
4795 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4796 this was also named trad_unix_bfd_copy_private_bfd_data.
4798 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4800 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4801 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4802 returns NULL, it is not an error. It's possible that some of
4803 these checks are not necessary (because the size can never be
4804 zero), but putting in the checks is the conservative thing to do
4805 in light of the fact that some of these malloc calls replaced
4806 unchecked alloca calls, in which a zero argument would work fine.
4808 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4810 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4811 duplicate definition.
4812 (osf_core_bfd_is_local_label): Define.
4814 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4815 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4816 failure indication, it merely means there are no relocs.
4818 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4819 after NAME, since SunOS /bin/cc can't handle it.
4821 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4823 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4824 From sukes@glue.umd.edu (Tasuki Hirata).
4826 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4828 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4829 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4830 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4832 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4834 * som.c (som_prep_for_fixups): Detect section symbols based
4835 on either the lack of private data or the symbol flags. Do not
4836 munge section symbol names anymore -- they no longer confuse GDB.
4837 (som_begin_writing): Leave space for an exec header if writing
4839 (som_slurp_symbol_table): Recognize both forms of section symbol
4840 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4841 section symbols to be the name of the section they represent.
4842 Debugging symbols begin with "L$0\001", not just "L$".
4844 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4846 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4848 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4849 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4850 and bfd_is_local_label.
4852 * targets.c: Add new entries to the bfd_target structure.
4854 * bfd.c (bfd_copy_private_bfd_data): New definition.

4864 * *-core.c: Provide default definitions for new functions in
4865 the target vector which all point to bfd_false.
4867 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4868 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4869 Default new vectors for copying private backend data to bfd_true.
4870 Default new vector for determining if a symbol is a local label
4871 to bfd_generic_is_local_label.
4873 * som.c (som_bfd_copy_private_section_data): New function.
4874 (som_bfd_is_local_label): New function.
4875 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4877 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4879 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4881 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4883 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4886 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4887 Indent some of them to GNU standards.
4889 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4890 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4891 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4892 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4893 Update copyright years.
4895 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4897 * som.c (som_prep_for_fixups): A relocation involving the section
4898 symbol for the *ABS* section is really a relocation involving
4900 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4901 undefined symbols. Correctly distinguish between debugger symbols
4902 and section symbols.
4904 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4905 for spaces and subspaces.
4907 * som.c (som_bfd_count_ar_symbols): Fix typo.
4909 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4910 HAS_RELOC based on the object's magic number.
4911 (make_unique_section): Delete function. BFD and its users are
4912 prepared to handle multiple sections with the same name.
4913 (setup_sections): Allocate space on the BFD's obstack to hold
4914 section names. Use bfd_make_setion_anyway rather than the
4915 obsolete make_unique_section.
4916 (som_prep_headers): Choose the correct SOM magic number based
4918 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4938 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4940 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4941 cruft (like the #pragma alloca for AIX).
4942 In addition to that problem, the C alloca calls xmalloc, which
4943 means checking for being out of memory can't work right. The
4944 following changes remove all uses of alloca from BFD.
4945 * hosts/solaris2.h: Remove alloca cruft.
4946 * som.c: Replace alloca with a fixed size auto array.

4951 * linker.c: Replace alloca with obstack_alloc.
4952 * libbfd.h: Rebuilt.
4954 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)

4959 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4961 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4962 Elf*_Off typedefs by their expansion, the typedefs have been
4963 removed from include/elf/internal.h.
4964 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4965 SHT_PROGBITS section.
4967 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4969 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4975 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4976 return from bfd_seek indicates an error.
4977 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4978 TRAD_CORE_STACK_OFFSET.
4979 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4980 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4982 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4984 * som.[ch]: Do not include libhppa.h in som.c, instead include
4987 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4988 include it in elf32-hppa.h.
4990 * som.c (log2): Return -1 on error rather than aborting.
4991 (setup_sections): Bubble up an error from log2.
4993 * Changes to make HP C compiler happy in both traditional
4995 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4997 (bfd_som_set_section_attributes): Use unsigned int rather than
4998 unsigned char to avoid GNU-C extensions.
4999 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5000 or failure rather than aborting on failure.
5002 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5004 (bfd_som_attach_aux_hdr): Add prototype.
5005 (hppa_som-gen_reloc_type): Likewise.

5039 unused symbols argument.
5041 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5043 Set reloc->sym_ptr_ptr appropriately.
5044 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5045 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5046 argument. Use the output symbols when canonicalizing the relocs,
5047 creating them if necessary.
5049 * linker.c (_bfd_generic_link_output_symbols): Do not
5050 rebuild/clobber the output symbols if they already exist.

5064 PARAMize and staticize rest of functions. Delete unused
5065 functions. Delete unused/unnecessary arguments to some functions.

5067 error code propogation working. Work on spacing and indention.
5068 Add FIXMEs for unresolved problems. Use enums rather than
5069 #defines for lots of things. Merge two functions which build
5070 linker stubs into a single function (so they can easily share a
5071 ton of common code).
5073 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5075 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5076 avoid depending upon right shifts of signed numbers, and to
5077 correct handling of src_mask with lower bits zero.

5109 (elf_hppa_final_processing): Add extern decl.
5111 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5112 comments. PARAMize some static functions. Delete unused functions.

5114 static vars together. Collapse common case statements together
5115 in many places. Use default case when possible instead of listing
5116 each case separately. Abort for bad errors until we get error
5117 code propogation working. Work on spacing and indention problems.
5118 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5119 COMPLEX relocation support (it's never used anyway).
5120 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5121 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5122 (elf_hppa_tc_make_sections): Likewise.

5163 * elfcode.h (alloca): Delete declaration.
5165 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5166 number rather than HP9000S800_ID. Note som.c is careful
5167 to make sure CPU_PA_RISC1_0 is always defined.
5169 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5171 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5188 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
5189 operation to avoid OSF 1.3 cc bug.
5190 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
5191 and bss_size bfd_size_type instead of unsigned long. Make
5192 text_start and data_start bfd_vma instead of unsigned long.
5193 * ecofflink.c (ecoff_add_string): Remove incorrect cast of return
5196 Sun Feb 20 16:06:54 1994 Ian Lance Taylor (ian@lisa.cygnus.com)

5709 * srec.c (srec_write_record): Put CONST keyword for "src" before
5710 "unsigned", some compilers don't like it after "unsigned".
5711 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5829 (only testing for m68k and vax at the moment); do verify that the
5830 preprocessor didn't trash the arch name inside the string version.

5861 bfd_som_set_subsection_attributes): Change parameters from char
5862 to int. Following a prototype with an old-style function definition

5969 use get_value to get the symbol value and check for undefined
5971 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5972 undefined, look it up in the linker hash table.
5974 * aoutx.h (translate_symbol_table): The string index 0 has a

5999 The sparc (and possibly other?) NLM format requires a different
6000 way to write exports, so add a write_export field to the backend
6001 data (and set it to NULL for everything but the sparc).

6051 read_dynamic_relocs fields.
6052 * aout-target.h (MY(backend_data)): Initialize
