1058 an empty .plt section.
1059 (elf32_sparc_relocate_section): For a GOT reloc against a global
1060 symbol when no dynamic object was seen, initialize the contents of
1061 the .got section. For a GOT reloc against a local symbol, only
1062 create a R_SPARC_RELATIVE reloc when generating a shared object.
1063 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1064 create a PLT entry as a R_SPARC_WDISP30 reloc.
1065 (elf32_sparc_finish_dynamic_sections): Only fiddle with the

4746 Fill in some fields in the space/subspace headers from the
4748 (som_bfd_copy_private_section_data): Only copy the stuff
4749 that we really need to make objcopy and strip work. Allocate
4750 the copy_data structure for the output bfd before copying.

4753 info that must be preserved when running objcopy/strip.

4755 macro. Add some comments on how the various fields are used.
4756 (som_section_data_struct): Make is_space and is_subspace bitfields.

4764 (som_mkobject): Do not allocate space for a file header here.
4765 It is not used when only reading SOM objects.
4766 (som_prep_headers): Allocate space for and attach a file header
4767 to the output bfd. For executables, use the saved system_id
4768 value rather than trying to guess the right value. Do not abort
4769 wwhen setting file_hdr->entry* for executables.
4770 (som_begin_writing): For executables, set the exec_entry and
4772 (som_copy_private_backend_section_data): Always return a value.
4774 * libhppa.h (PA_PAGESIZE): Define.
4776 * som.c (SOM_ALIGN): Define.
4777 (som_begin_writing): If writing an executable, initialize all
4778 fields in the exec header to zero. Update fields in the exec
4779 header as sizes of loadable subspaces are computed. Carefully
4780 preserve alignments when building executables. Actually write the
4781 exec after all the fields are filled in.
4783 * Better long-filename handling. Reads SOM ABI compliant extended
4784 names, but doesn't quite write compliant extended names yet.
4785 * som.c (som_slurp_extended_name_table): Delete function. The
4786 generic code will handle things correctly.
4787 (som_slurp_armap): Seek to the beginning of the next member.
4788 (normalize): New function.
4789 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4790 name table into account when computing the file offsets in the
4791 SOM dictionary. Make sure to align to an even boundary.
4792 (som_write_armap): Initialize the checksum to zero.
4793 (ar_maxchars): Fix. Opps.
4795 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4797 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4798 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4800 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4802 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4803 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4804 * bfd-in2.h: Regenerated.
4806 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4807 this was also named trad_unix_bfd_copy_private_bfd_data.
4809 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4811 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4812 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4813 returns NULL, it is not an error. It's possible that some of
4814 these checks are not necessary (because the size can never be
4815 zero), but putting in the checks is the conservative thing to do
4816 in light of the fact that some of these malloc calls replaced
4817 unchecked alloca calls, in which a zero argument would work fine.
4819 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4821 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4822 duplicate definition.
4823 (osf_core_bfd_is_local_label): Define.
4825 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4826 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4827 failure indication, it merely means there are no relocs.
4829 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4830 after NAME, since SunOS /bin/cc can't handle it.
4832 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4834 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4835 From sukes@glue.umd.edu (Tasuki Hirata).
4837 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4839 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4840 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4841 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4843 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4845 * som.c (som_prep_for_fixups): Detect section symbols based
4846 on either the lack of private data or the symbol flags. Do not
4847 munge section symbol names anymore -- they no longer confuse GDB.
4848 (som_begin_writing): Leave space for an exec header if writing
4850 (som_slurp_symbol_table): Recognize both forms of section symbol
4851 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4852 section symbols to be the name of the section they represent.
4853 Debugging symbols begin with "L$0\001", not just "L$".
4855 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4857 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4859 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4860 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4861 and bfd_is_local_label.
4863 * targets.c: Add new entries to the bfd_target structure.
4865 * bfd.c (bfd_copy_private_bfd_data): New definition.

4873 * libbfd.c (bfd_generic_is_local_label): New function.
4875 * *-core.c: Provide default definitions for new functions in
4876 the target vector which all point to bfd_false.
4878 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4879 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4880 Default new vectors for copying private backend data to bfd_true.
4881 Default new vector for determining if a symbol is a local label
4882 to bfd_generic_is_local_label.
4884 * som.c (som_bfd_copy_private_section_data): New function.
4885 (som_bfd_is_local_label): New function.
4886 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4888 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4890 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4892 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4894 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4897 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4898 Indent some of them to GNU standards.
4900 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4901 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4902 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4903 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4904 Update copyright years.
4906 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4908 * som.c (som_prep_for_fixups): A relocation involving the section
4909 symbol for the *ABS* section is really a relocation involving
4911 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4912 undefined symbols. Correctly distinguish between debugger symbols
4913 and section symbols.
4915 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4916 for spaces and subspaces.
4918 * som.c (som_bfd_count_ar_symbols): Fix typo.
4920 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4921 HAS_RELOC based on the object's magic number.
4922 (make_unique_section): Delete function. BFD and its users are
4923 prepared to handle multiple sections with the same name.
4924 (setup_sections): Allocate space on the BFD's obstack to hold
4925 section names. Use bfd_make_setion_anyway rather than the
4926 obsolete make_unique_section.
4927 (som_prep_headers): Choose the correct SOM magic number based
4929 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4943 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4944 is always located at the start of the data section to allow
4945 recovery of the dynamic info from a stripped executable.

4949 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4951 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4952 cruft (like the #pragma alloca for AIX).
4953 In addition to that problem, the C alloca calls xmalloc, which
4954 means checking for being out of memory can't work right. The
4955 following changes remove all uses of alloca from BFD.
4956 * hosts/solaris2.h: Remove alloca cruft.
4957 * som.c: Replace alloca with a fixed size auto array.

4960 sunos.c: Replace alloca with malloc and appropriate error checking and
4962 * linker.c: Replace alloca with obstack_alloc.
4963 * libbfd.h: Rebuilt.
4965 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4967 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4970 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4972 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4973 Elf*_Off typedefs by their expansion, the typedefs have been
4974 removed from include/elf/internal.h.
4975 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4976 SHT_PROGBITS section.
4978 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4980 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4986 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4987 return from bfd_seek indicates an error.
4988 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4989 TRAD_CORE_STACK_OFFSET.
4990 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4991 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4993 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4995 * som.[ch]: Do not include libhppa.h in som.c, instead include
4998 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4999 include it in elf32-hppa.h.
5001 * som.c (log2): Return -1 on error rather than aborting.
5002 (setup_sections): Bubble up an error from log2.
5004 * Changes to make HP C compiler happy in both traditional
5006 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5008 (bfd_som_set_section_attributes): Use unsigned int rather than
5009 unsigned char to avoid GNU-C extensions.
5010 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5011 or failure rather than aborting on failure.
5013 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5015 (bfd_som_attach_aux_hdr): Add prototype.
5016 (hppa_som-gen_reloc_type): Likewise.

5050 unused symbols argument.
5052 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5054 Set reloc->sym_ptr_ptr appropriately.
5055 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5056 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5057 argument. Use the output symbols when canonicalizing the relocs,
5058 creating them if necessary.
5060 * linker.c (_bfd_generic_link_output_symbols): Do not
5061 rebuild/clobber the output symbols if they already exist.
5063 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)

5075 PARAMize and staticize rest of functions. Delete unused
5076 functions. Delete unused/unnecessary arguments to some functions.
5077 Group static vars together. Abort for bad errors until we have
5078 error code propogation working. Work on spacing and indention.
5079 Add FIXMEs for unresolved problems. Use enums rather than
5080 #defines for lots of things. Merge two functions which build
5081 linker stubs into a single function (so they can easily share a
5082 ton of common code).
5084 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5086 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5087 avoid depending upon right shifts of signed numbers, and to
5088 correct handling of src_mask with lower bits zero.

5120 (elf_hppa_final_processing): Add extern decl.
5122 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5123 comments. PARAMize some static functions. Delete unused functions.
5124 Delete unused/unnecessary arguments to many functions. Group
5125 static vars together. Collapse common case statements together
5126 in many places. Use default case when possible instead of listing
5127 each case separately. Abort for bad errors until we get error
5128 code propogation working. Work on spacing and indention problems.
5129 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5130 COMPLEX relocation support (it's never used anyway).
5131 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5132 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5133 (elf_hppa_tc_make_sections): Likewise.

5174 * elfcode.h (alloca): Delete declaration.
5176 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5177 number rather than HP9000S800_ID. Note som.c is careful
5178 to make sure CPU_PA_RISC1_0 is always defined.
5180 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5182 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5199 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
5200 operation to avoid OSF 1.3 cc bug.
5201 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
5202 and bss_size bfd_size_type instead of unsigned long. Make
5203 text_start and data_start bfd_vma instead of unsigned long.
5204 * ecofflink.c (ecoff_add_string): Remove incorrect cast of return
5207 Sun Feb 20 16:06:54 1994 Ian Lance Taylor (ian@lisa.cygnus.com)

5720 * srec.c (srec_write_record): Put CONST keyword for "src" before
5721 "unsigned", some compilers don't like it after "unsigned".
5722 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5872 bfd_som_set_subsection_attributes): Change parameters from char
5873 to int. Following a prototype with an old-style function definition

5980 use get_value to get the symbol value and check for undefined
5982 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5983 undefined, look it up in the linker hash table.
5985 * aoutx.h (translate_symbol_table): The string index 0 has a

6010 The sparc (and possibly other?) NLM format requires a different
6011 way to write exports, so add a write_export field to the backend
6012 data (and set it to NULL for everything but the sparc).

6062 read_dynamic_relocs fields.
6063 * aout-target.h (MY(backend_data)): Initialize
