1040 an empty .plt section.
1041 (elf32_sparc_relocate_section): For a GOT reloc against a global
1042 symbol when no dynamic object was seen, initialize the contents of
1043 the .got section. For a GOT reloc against a local symbol, only
1044 create a R_SPARC_RELATIVE reloc when generating a shared object.
1045 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1046 create a PLT entry as a R_SPARC_WDISP30 reloc.

4760 fields in the exec header to zero. Update fields in the exec
4761 header as sizes of loadable subspaces are computed. Carefully
4762 preserve alignments when building executables. Actually write the
4763 exec after all the fields are filled in.
4765 * Better long-filename handling. Reads SOM ABI compliant extended
4766 names, but doesn't quite write compliant extended names yet.
4767 * som.c (som_slurp_extended_name_table): Delete function. The
4768 generic code will handle things correctly.
4769 (som_slurp_armap): Seek to the beginning of the next member.
4770 (normalize): New function.
4771 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4772 name table into account when computing the file offsets in the
4773 SOM dictionary. Make sure to align to an even boundary.
4774 (som_write_armap): Initialize the checksum to zero.
4775 (ar_maxchars): Fix. Opps.
4777 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4779 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4780 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4782 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4784 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4785 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4786 * bfd-in2.h: Regenerated.
4788 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4789 this was also named trad_unix_bfd_copy_private_bfd_data.
4791 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4793 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4794 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4795 returns NULL, it is not an error. It's possible that some of
4796 these checks are not necessary (because the size can never be
4797 zero), but putting in the checks is the conservative thing to do
4798 in light of the fact that some of these malloc calls replaced
4799 unchecked alloca calls, in which a zero argument would work fine.
4801 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4803 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4804 duplicate definition.
4805 (osf_core_bfd_is_local_label): Define.
4807 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4808 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4809 failure indication, it merely means there are no relocs.
4811 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4812 after NAME, since SunOS /bin/cc can't handle it.
4814 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4816 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4817 From sukes@glue.umd.edu (Tasuki Hirata).
4819 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4821 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4822 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4823 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4825 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4827 * som.c (som_prep_for_fixups): Detect section symbols based
4828 on either the lack of private data or the symbol flags. Do not
4829 munge section symbol names anymore -- they no longer confuse GDB.
4830 (som_begin_writing): Leave space for an exec header if writing
4832 (som_slurp_symbol_table): Recognize both forms of section symbol
4833 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4834 section symbols to be the name of the section they represent.
4835 Debugging symbols begin with "L$0\001", not just "L$".
4837 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4839 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4841 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4842 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4843 and bfd_is_local_label.
4845 * targets.c: Add new entries to the bfd_target structure.
4847 * bfd.c (bfd_copy_private_bfd_data): New definition.

4855 * libbfd.c (bfd_generic_is_local_label): New function.
4857 * *-core.c: Provide default definitions for new functions in
4858 the target vector which all point to bfd_false.
4860 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4861 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4862 Default new vectors for copying private backend data to bfd_true.
4863 Default new vector for determining if a symbol is a local label
4864 to bfd_generic_is_local_label.
4866 * som.c (som_bfd_copy_private_section_data): New function.
4867 (som_bfd_is_local_label): New function.
4868 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4870 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4872 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4874 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4876 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4879 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4880 Indent some of them to GNU standards.
4882 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4883 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4884 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4885 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4886 Update copyright years.
4888 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4890 * som.c (som_prep_for_fixups): A relocation involving the section
4891 symbol for the *ABS* section is really a relocation involving
4893 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4894 undefined symbols. Correctly distinguish between debugger symbols
4895 and section symbols.
4897 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4898 for spaces and subspaces.
4900 * som.c (som_bfd_count_ar_symbols): Fix typo.
4902 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4903 HAS_RELOC based on the object's magic number.
4904 (make_unique_section): Delete function. BFD and its users are
4905 prepared to handle multiple sections with the same name.
4906 (setup_sections): Allocate space on the BFD's obstack to hold
4907 section names. Use bfd_make_setion_anyway rather than the
4908 obsolete make_unique_section.
4909 (som_prep_headers): Choose the correct SOM magic number based
4911 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4913 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4915 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4925 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4926 is always located at the start of the data section to allow
4927 recovery of the dynamic info from a stripped executable.
4928 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4931 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4933 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4934 cruft (like the #pragma alloca for AIX).
4935 In addition to that problem, the C alloca calls xmalloc, which
4936 means checking for being out of memory can't work right. The
4937 following changes remove all uses of alloca from BFD.
4938 * hosts/solaris2.h: Remove alloca cruft.
4939 * som.c: Replace alloca with a fixed size auto array.
4940 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

4942 sunos.c: Replace alloca with malloc and appropriate error checking and
4944 * linker.c: Replace alloca with obstack_alloc.
4945 * libbfd.h: Rebuilt.
4947 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4949 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4952 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4954 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4955 Elf*_Off typedefs by their expansion, the typedefs have been
4956 removed from include/elf/internal.h.
4957 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4958 SHT_PROGBITS section.
4960 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4962 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4968 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4969 return from bfd_seek indicates an error.
4970 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4971 TRAD_CORE_STACK_OFFSET.
4972 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4973 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4975 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4977 * som.[ch]: Do not include libhppa.h in som.c, instead include
4980 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4981 include it in elf32-hppa.h.
4983 * som.c (log2): Return -1 on error rather than aborting.
4984 (setup_sections): Bubble up an error from log2.
4986 * Changes to make HP C compiler happy in both traditional
4988 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4990 (bfd_som_set_section_attributes): Use unsigned int rather than
4991 unsigned char to avoid GNU-C extensions.
4992 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4993 or failure rather than aborting on failure.
4995 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4997 (bfd_som_attach_aux_hdr): Add prototype.
4998 (hppa_som-gen_reloc_type): Likewise.

5032 unused symbols argument.
5034 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5036 Set reloc->sym_ptr_ptr appropriately.
5037 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5038 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5039 argument. Use the output symbols when canonicalizing the relocs,
5040 creating them if necessary.
5042 * linker.c (_bfd_generic_link_output_symbols): Do not
5043 rebuild/clobber the output symbols if they already exist.
5045 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5047 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5057 PARAMize and staticize rest of functions. Delete unused
5058 functions. Delete unused/unnecessary arguments to some functions.
5059 Group static vars together. Abort for bad errors until we have
5060 error code propogation working. Work on spacing and indention.
5061 Add FIXMEs for unresolved problems. Use enums rather than
5062 #defines for lots of things. Merge two functions which build
5063 linker stubs into a single function (so they can easily share a
5064 ton of common code).
5066 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5068 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5069 avoid depending upon right shifts of signed numbers, and to
5070 correct handling of src_mask with lower bits zero.

5101 (elf_hppa_tc_make_sections): Likewise.
5102 (elf_hppa_final_processing): Add extern decl.
5104 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5105 comments. PARAMize some static functions. Delete unused functions.

5107 static vars together. Collapse common case statements together
5108 in many places. Use default case when possible instead of listing
5109 each case separately. Abort for bad errors until we get error
5110 code propogation working. Work on spacing and indention problems.
5111 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5112 COMPLEX relocation support (it's never used anyway).
5113 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5114 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5115 (elf_hppa_tc_make_sections): Likewise.

5156 * elfcode.h (alloca): Delete declaration.
5158 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5159 number rather than HP9000S800_ID. Note som.c is careful
5160 to make sure CPU_PA_RISC1_0 is always defined.
5162 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5164 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5181 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
5182 operation to avoid OSF 1.3 cc bug.
5183 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
5184 and bss_size bfd_size_type instead of unsigned long. Make
5185 text_start and data_start bfd_vma instead of unsigned long.
5186 * ecofflink.c (ecoff_add_string): Remove incorrect cast of return
5189 Sun Feb 20 16:06:54 1994 Ian Lance Taylor (ian@lisa.cygnus.com)

5288 bother processing them.

5854 bfd_som_set_subsection_attributes): Change parameters from char
5855 to int. Following a prototype with an old-style function definition

5962 use get_value to get the symbol value and check for undefined
5964 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5965 undefined, look it up in the linker hash table.
5967 * aoutx.h (translate_symbol_table): The string index 0 has a

5992 The sparc (and possibly other?) NLM format requires a different
5993 way to write exports, so add a write_export field to the backend
5994 data (and set it to NULL for everything but the sparc).

6044 read_dynamic_relocs fields.
6045 * aout-target.h (MY(backend_data)): Initialize
