1045 an empty .plt section.
1046 (elf32_sparc_relocate_section): For a GOT reloc against a global
1047 symbol when no dynamic object was seen, initialize the contents of
1048 the .got section. For a GOT reloc against a local symbol, only
1049 create a R_SPARC_RELATIVE reloc when generating a shared object.
1050 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1051 create a PLT entry as a R_SPARC_WDISP30 reloc.

4733 Fill in some fields in the space/subspace headers from the
4735 (som_bfd_copy_private_section_data): Only copy the stuff
4736 that we really need to make objcopy and strip work. Allocate

4755 value rather than trying to guess the right value. Do not abort
4756 wwhen setting file_hdr->entry* for executables.
4757 (som_begin_writing): For executables, set the exec_entry and
4759 (som_copy_private_backend_section_data): Always return a value.
4761 * libhppa.h (PA_PAGESIZE): Define.
4763 * som.c (SOM_ALIGN): Define.
4764 (som_begin_writing): If writing an executable, initialize all
4765 fields in the exec header to zero. Update fields in the exec
4766 header as sizes of loadable subspaces are computed. Carefully
4767 preserve alignments when building executables. Actually write the
4768 exec after all the fields are filled in.
4770 * Better long-filename handling. Reads SOM ABI compliant extended
4771 names, but doesn't quite write compliant extended names yet.
4772 * som.c (som_slurp_extended_name_table): Delete function. The
4773 generic code will handle things correctly.
4774 (som_slurp_armap): Seek to the beginning of the next member.
4775 (normalize): New function.
4776 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4777 name table into account when computing the file offsets in the
4778 SOM dictionary. Make sure to align to an even boundary.
4779 (som_write_armap): Initialize the checksum to zero.
4780 (ar_maxchars): Fix. Opps.
4782 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4784 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4785 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4787 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4789 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4790 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4791 * bfd-in2.h: Regenerated.
4793 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4794 this was also named trad_unix_bfd_copy_private_bfd_data.
4796 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4798 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4799 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4800 returns NULL, it is not an error. It's possible that some of
4801 these checks are not necessary (because the size can never be
4802 zero), but putting in the checks is the conservative thing to do
4803 in light of the fact that some of these malloc calls replaced
4804 unchecked alloca calls, in which a zero argument would work fine.
4806 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4808 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4809 duplicate definition.
4810 (osf_core_bfd_is_local_label): Define.
4812 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4813 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4814 failure indication, it merely means there are no relocs.
4816 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4817 after NAME, since SunOS /bin/cc can't handle it.
4819 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4821 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4822 From sukes@glue.umd.edu (Tasuki Hirata).
4824 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4826 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4827 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4828 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4830 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4832 * som.c (som_prep_for_fixups): Detect section symbols based
4833 on either the lack of private data or the symbol flags. Do not
4834 munge section symbol names anymore -- they no longer confuse GDB.
4835 (som_begin_writing): Leave space for an exec header if writing
4837 (som_slurp_symbol_table): Recognize both forms of section symbol
4838 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4839 section symbols to be the name of the section they represent.
4840 Debugging symbols begin with "L$0\001", not just "L$".
4842 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4844 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4846 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4847 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4848 and bfd_is_local_label.
4850 * targets.c: Add new entries to the bfd_target structure.
4852 * bfd.c (bfd_copy_private_bfd_data): New definition.

4863 the target vector which all point to bfd_false.
4865 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4866 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4867 Default new vectors for copying private backend data to bfd_true.
4868 Default new vector for determining if a symbol is a local label
4869 to bfd_generic_is_local_label.
4871 * som.c (som_bfd_copy_private_section_data): New function.
4872 (som_bfd_is_local_label): New function.
4873 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4875 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4877 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4879 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4881 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4884 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4885 Indent some of them to GNU standards.
4887 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4888 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4889 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4890 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4891 Update copyright years.
4893 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4895 * som.c (som_prep_for_fixups): A relocation involving the section
4896 symbol for the *ABS* section is really a relocation involving
4898 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4899 undefined symbols. Correctly distinguish between debugger symbols
4900 and section symbols.
4902 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4903 for spaces and subspaces.
4905 * som.c (som_bfd_count_ar_symbols): Fix typo.
4907 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4908 HAS_RELOC based on the object's magic number.
4909 (make_unique_section): Delete function. BFD and its users are
4910 prepared to handle multiple sections with the same name.
4911 (setup_sections): Allocate space on the BFD's obstack to hold
4912 section names. Use bfd_make_setion_anyway rather than the
4913 obsolete make_unique_section.
4914 (som_prep_headers): Choose the correct SOM magic number based
4916 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4936 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4938 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4939 cruft (like the #pragma alloca for AIX).
4940 In addition to that problem, the C alloca calls xmalloc, which
4941 means checking for being out of memory can't work right. The
4942 following changes remove all uses of alloca from BFD.
4943 * hosts/solaris2.h: Remove alloca cruft.
4944 * som.c: Replace alloca with a fixed size auto array.

4949 * linker.c: Replace alloca with obstack_alloc.
4950 * libbfd.h: Rebuilt.
4952 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)

4957 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4959 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4960 Elf*_Off typedefs by their expansion, the typedefs have been
4961 removed from include/elf/internal.h.
4962 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4963 SHT_PROGBITS section.
4965 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4967 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4973 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4974 return from bfd_seek indicates an error.
4975 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4976 TRAD_CORE_STACK_OFFSET.
4977 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4978 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4980 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4982 * som.[ch]: Do not include libhppa.h in som.c, instead include
4985 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4986 include it in elf32-hppa.h.
4988 * som.c (log2): Return -1 on error rather than aborting.
4989 (setup_sections): Bubble up an error from log2.
4991 * Changes to make HP C compiler happy in both traditional
4993 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4995 (bfd_som_set_section_attributes): Use unsigned int rather than
4996 unsigned char to avoid GNU-C extensions.
4997 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4998 or failure rather than aborting on failure.
5000 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5002 (bfd_som_attach_aux_hdr): Add prototype.
5003 (hppa_som-gen_reloc_type): Likewise.

5041 Set reloc->sym_ptr_ptr appropriately.
5042 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5043 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5044 argument. Use the output symbols when canonicalizing the relocs,
5045 creating them if necessary.
5047 * linker.c (_bfd_generic_link_output_symbols): Do not
5048 rebuild/clobber the output symbols if they already exist.

5062 PARAMize and staticize rest of functions. Delete unused
5063 functions. Delete unused/unnecessary arguments to some functions.

5065 error code propogation working. Work on spacing and indention.
5066 Add FIXMEs for unresolved problems. Use enums rather than
5067 #defines for lots of things. Merge two functions which build
5068 linker stubs into a single function (so they can easily share a
5069 ton of common code).
5071 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5073 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5074 avoid depending upon right shifts of signed numbers, and to
5075 correct handling of src_mask with lower bits zero.

5107 (elf_hppa_final_processing): Add extern decl.
5109 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5110 comments. PARAMize some static functions. Delete unused functions.

5112 static vars together. Collapse common case statements together
5113 in many places. Use default case when possible instead of listing
5114 each case separately. Abort for bad errors until we get error
5115 code propogation working. Work on spacing and indention problems.
5116 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5117 COMPLEX relocation support (it's never used anyway).
5118 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5119 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5120 (elf_hppa_tc_make_sections): Likewise.

5163 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5164 number rather than HP9000S800_ID. Note som.c is careful
5165 to make sure CPU_PA_RISC1_0 is always defined.
5167 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5169 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5186 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
5187 operation to avoid OSF 1.3 cc bug.
5188 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
5189 and bss_size bfd_size_type instead of unsigned long. Make
5190 text_start and data_start bfd_vma instead of unsigned long.
5191 * ecofflink.c (ecoff_add_string): Remove incorrect cast of return
5194 Sun Feb 20 16:06:54 1994 Ian Lance Taylor (ian@lisa.cygnus.com)

5707 * srec.c (srec_write_record): Put CONST keyword for "src" before
5708 "unsigned", some compilers don't like it after "unsigned".
5709 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5781 _bfd_generic_link_write_global_symbol): Don't require that all

5859 bfd_som_set_subsection_attributes): Change parameters from char
5860 to int. Following a prototype with an old-style function definition

5967 use get_value to get the symbol value and check for undefined
5969 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5970 undefined, look it up in the linker hash table.
5972 * aoutx.h (translate_symbol_table): The string index 0 has a

5997 The sparc (and possibly other?) NLM format requires a different
5998 way to write exports, so add a write_export field to the backend
5999 data (and set it to NULL for everything but the sparc).
