1276 of the .plt section.
1277 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
1278 seen, skip most of this function, and force the size of the

1280 an empty .plt section.
1281 (elf32_sparc_relocate_section): For a GOT reloc against a global
1282 symbol when no dynamic object was seen, initialize the contents of
1283 the .got section. For a GOT reloc against a local symbol, only

4811 in asymbol udata field.
4813 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4815 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4816 reloc, used in embedded PIC code.
4817 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

4825 add_symbls entry point.
4827 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4828 counting relocs. Set SEC_RELOC flag for any section which has

4834 generic_link_add_symbols.
4835 (_bfd_generic_link_add_symbols_collect): New function, like
4836 _bfd_generic_link_add_symbols but also collect constructors and
4837 destructors by name as collect2 does.
4838 (generic_link_add_symbols): New function, like old
4839 _bfd_generic_link_add_symbols but with collect argument.
4840 (generic_link_add_object_symbols): Take collect argument.

4852 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
4853 for first character in an extended name.
4854 (_bfd_write_archive_contents): If ar_padchar == '/', then use
4855 "//" as the name of the special archive member holding the
4856 extended name table.
4858 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4860 Support for link_order types which generate relocs in order to
4861 support -Ur in the linker.
4862 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4863 from call to _bfd_generic_link_add_one_symbol.
4864 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4865 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4866 instead of bitsize to add_to_set call back.
4867 (_bfd_generic_final_link): Account for link_order relocs when
4868 allocating space for relocations. Handle them in link_order loop.
4869 (_bfd_generic_reloc_link_order): New function.
4870 (_bfd_default_link_order): If a reloc_link_order is seen here,
4872 (_bfd_count_link_order_relocs): New function.
4873 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4874 argument from declaration.
4875 (_bfd_generic_reloc_link_order): Declare.

4885 call to _bfd_generic_link_add_one_symbol.
4886 (ecoff_bfd_final_link): Account for link_order relocs when
4887 allocating space for relocations. Handle them in link_order loop.
4888 (ecoff_link_write_external): Set the storage class of a defined
4889 linker created symbol based on the section it is in. Correct
4890 bfd_link_hash_weak case to use .sc rather than .st.
4891 (ecoff_reloc_link_order): New function.
4892 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4894 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4900 bfd_zmalloc. Free a pointer, not a union.
4901 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4903 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4905 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4907 * som.c (bfd_section_from_som_symbol): Only to do the value
4908 comparison for function symbols within executables.
4910 * som.c (bfd_section_from_som_symbol): Renamed from
4911 som_section_from_subspace_index. Pass in a native SOM symbol.
4912 For executables, iterate through the sections to find out
4913 which contains the symbol's address rather than using the
4914 symbol_info field. (symbol_info has a different meaning for
4915 dynamicly linked executables.)
4917 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4920 * som.c (som_begin_writing): Fix braino (one call to align
4921 space/subspace data was done unconditionally rather than
4922 just for executables.)
4924 * som.c (som_begin_writing): Align text in all executables to
4925 make HPUX kernel happy. Fixes strip/objcopy for shared
4928 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4930 * som.c (som_begin_writing): Account for alignment needs of
4931 subspaces too when writing executables. Never request a negative
4932 bss size. Fixes some problems with demand paged executables,
4933 still having problems with pure executables and shared executables.
4935 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4937 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4938 bfd_zalloc for rawptr, because later on we may call free, not
4941 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4942 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4943 * cisco-core.c: New file.
4944 * Makefile.in: Change accordingly.
4945 * configure.in: Recognize cisco_core_vec.
4946 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4947 * targets.c: Add cisco_core_vec.
4948 * bfd-in2.h: Rebuilt.
4950 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4952 * som.h (som_copyable_section_data_struct): New structure
4953 containing all the private section information which needs
4954 to be copied from input section to output section during
4956 (som_section_data_struct): Remove several fields now in
4957 som_copyable_section_data_struct. Make the space and
4958 subspace dictionaries be pointers (to save space when
4959 only reading objects).
4961 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4962 some references changed. Allocate a copyable data stucture if
4963 none exists. Store info into the copyable data structure.
4964 (bfd_som_set_subsection_attributes): Likewise.
4965 (som_is_space, som_is_subspace, som_is_container): New functions.
4966 Use these instead of directly accessing private data.
4967 (som_prep_headers): Allocate space and subspace headers here.
4968 Fill in some fields in the space/subspace headers from the
4970 (som_bfd_copy_private_section_data): Only copy the stuff
4971 that we really need to make objcopy and strip work. Allocate
4972 the copy_data structure for the output bfd before copying.
4974 * som.h (struct som_exec_data): New structure to hold exec
4975 info that must be preserved when running objcopy/strip.
4976 (struct somdata): Add new "exec_data" field and accessor
4977 macro. Add some comments on how the various fields are used.
4978 (som_section_data_struct): Make is_space and is_subspace bitfields.
4979 Delete unused subspace_index. All references now use the
4980 target_index field within the section structure itself.
4982 * som.c (make_unique_section): Delete unused declaration.
4983 (som_bfd_copy_private_bfd_data): New function.
4984 (som_object_setup): Allocate space for and save exec information
4985 that needs to be copied during objcopy/strip.
4986 (som_mkobject): Do not allocate space for a file header here.
4987 It is not used when only reading SOM objects.
4988 (som_prep_headers): Allocate space for and attach a file header
4989 to the output bfd. For executables, use the saved system_id
4990 value rather than trying to guess the right value. Do not abort
4991 wwhen setting file_hdr->entry* for executables.
4992 (som_begin_writing): For executables, set the exec_entry and
4994 (som_copy_private_backend_section_data): Always return a value.
4996 * libhppa.h (PA_PAGESIZE): Define.
4998 * som.c (SOM_ALIGN): Define.
4999 (som_begin_writing): If writing an executable, initialize all
5000 fields in the exec header to zero. Update fields in the exec
5001 header as sizes of loadable subspaces are computed. Carefully
5002 preserve alignments when building executables. Actually write the
5003 exec after all the fields are filled in.
5005 * Better long-filename handling. Reads SOM ABI compliant extended
5006 names, but doesn't quite write compliant extended names yet.
5007 * som.c (som_slurp_extended_name_table): Delete function. The
5008 generic code will handle things correctly.
5009 (som_slurp_armap): Seek to the beginning of the next member.
5010 (normalize): New function.
5011 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5012 name table into account when computing the file offsets in the
5013 SOM dictionary. Make sure to align to an even boundary.
5014 (som_write_armap): Initialize the checksum to zero.
5015 (ar_maxchars): Fix. Opps.
5017 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5019 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5020 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5022 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5024 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5025 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5026 * bfd-in2.h: Regenerated.
5028 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5029 this was also named trad_unix_bfd_copy_private_bfd_data.
5031 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5033 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5034 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5035 returns NULL, it is not an error. It's possible that some of
5036 these checks are not necessary (because the size can never be
5037 zero), but putting in the checks is the conservative thing to do
5038 in light of the fact that some of these malloc calls replaced
5039 unchecked alloca calls, in which a zero argument would work fine.
5041 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5043 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5044 duplicate definition.
5045 (osf_core_bfd_is_local_label): Define.
5047 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5048 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5049 failure indication, it merely means there are no relocs.
5051 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5052 after NAME, since SunOS /bin/cc can't handle it.
5054 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5056 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5057 From sukes@glue.umd.edu (Tasuki Hirata).
5059 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5061 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5062 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5063 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5065 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5067 * som.c (som_prep_for_fixups): Detect section symbols based
5068 on either the lack of private data or the symbol flags. Do not
5069 munge section symbol names anymore -- they no longer confuse GDB.
5070 (som_begin_writing): Leave space for an exec header if writing
5072 (som_slurp_symbol_table): Recognize both forms of section symbol
5073 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5074 section symbols to be the name of the section they represent.
5075 Debugging symbols begin with "L$0\001", not just "L$".
5077 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5079 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5081 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5082 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5083 and bfd_is_local_label.
5085 * targets.c: Add new entries to the bfd_target structure.
5087 * bfd.c (bfd_copy_private_bfd_data): New definition.
5089 * section.c (bfd_copy_private_section_data): New definition.

5095 * libbfd.c (bfd_generic_is_local_label): New function.
5097 * *-core.c: Provide default definitions for new functions in
5098 the target vector which all point to bfd_false.
5100 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5101 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5102 Default new vectors for copying private backend data to bfd_true.
5103 Default new vector for determining if a symbol is a local label
5104 to bfd_generic_is_local_label.
5106 * som.c (som_bfd_copy_private_section_data): New function.
5107 (som_bfd_is_local_label): New function.
5108 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5110 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5112 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5114 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5116 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5119 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5120 Indent some of them to GNU standards.
5122 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5123 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5124 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5125 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5126 Update copyright years.
5128 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5130 * som.c (som_prep_for_fixups): A relocation involving the section
5131 symbol for the *ABS* section is really a relocation involving
5133 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5134 undefined symbols. Correctly distinguish between debugger symbols
5135 and section symbols.
5137 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5138 for spaces and subspaces.
5140 * som.c (som_bfd_count_ar_symbols): Fix typo.
5142 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5143 HAS_RELOC based on the object's magic number.
5144 (make_unique_section): Delete function. BFD and its users are
5145 prepared to handle multiple sections with the same name.
5146 (setup_sections): Allocate space on the BFD's obstack to hold
5147 section names. Use bfd_make_setion_anyway rather than the
5148 obsolete make_unique_section.
5149 (som_prep_headers): Choose the correct SOM magic number based
5151 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5153 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5155 * elf32-ppc.c: Renamed from elf32-powerpc.c.

5165 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5166 is always located at the start of the data section to allow
5167 recovery of the dynamic info from a stripped executable.
5168 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5171 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5173 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5174 cruft (like the #pragma alloca for AIX).
5175 In addition to that problem, the C alloca calls xmalloc, which
5176 means checking for being out of memory can't work right. The
5177 following changes remove all uses of alloca from BFD.
5178 * hosts/solaris2.h: Remove alloca cruft.
5179 * som.c: Replace alloca with a fixed size auto array.

5184 * linker.c: Replace alloca with obstack_alloc.
5185 * libbfd.h: Rebuilt.
5187 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5189 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5192 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5194 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5195 Elf*_Off typedefs by their expansion, the typedefs have been
5196 removed from include/elf/internal.h.
5197 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5198 SHT_PROGBITS section.
5200 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5202 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5206 * configure.host: Recognize i[34]86-sequent-*.
5208 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5209 return from bfd_seek indicates an error.
5210 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5211 TRAD_CORE_STACK_OFFSET.
5212 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5213 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5215 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5217 * som.[ch]: Do not include libhppa.h in som.c, instead include
5220 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5221 include it in elf32-hppa.h.
5223 * som.c (log2): Return -1 on error rather than aborting.

5528 bother processing them.
5529 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6232 The sparc (and possibly other?) NLM format requires a different
6233 way to write exports, so add a write_export field to the backend
6234 data (and set it to NULL for everything but the sparc).
