1268 an empty .plt section.
1269 (elf32_sparc_relocate_section): For a GOT reloc against a global
1270 symbol when no dynamic object was seen, initialize the contents of
1271 the .got section. For a GOT reloc against a local symbol, only

4795 (_bfd_generic_final_link): Likewise.
4796 (_bfd_generic_link_output_symbols): Likewise.

4799 in asymbol udata field.
4801 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4803 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4804 reloc, used in embedded PIC code.
4805 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

4812 link_order loop. Use _bfd_generic_link_add_symbols_collect for
4813 add_symbls entry point.
4815 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4816 counting relocs. Set SEC_RELOC flag for any section which has

4821 * linker.c (_bfd_generic_link_add_symbols): Just call
4822 generic_link_add_symbols.
4823 (_bfd_generic_link_add_symbols_collect): New function, like
4824 _bfd_generic_link_add_symbols but also collect constructors and
4825 destructors by name as collect2 does.
4826 (generic_link_add_symbols): New function, like old
4827 _bfd_generic_link_add_symbols but with collect argument.
4828 (generic_link_add_object_symbols): Take collect argument.

4840 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
4841 for first character in an extended name.
4842 (_bfd_write_archive_contents): If ar_padchar == '/', then use
4843 "//" as the name of the special archive member holding the
4844 extended name table.
4846 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4848 Support for link_order types which generate relocs in order to
4849 support -Ur in the linker.
4850 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4851 from call to _bfd_generic_link_add_one_symbol.
4852 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4853 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4854 instead of bitsize to add_to_set call back.
4855 (_bfd_generic_final_link): Account for link_order relocs when
4856 allocating space for relocations. Handle them in link_order loop.
4857 (_bfd_generic_reloc_link_order): New function.
4858 (_bfd_default_link_order): If a reloc_link_order is seen here,
4860 (_bfd_count_link_order_relocs): New function.
4861 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4862 argument from declaration.
4863 (_bfd_generic_reloc_link_order): Declare.
4864 (_bfd_count_link_order_relocs): Declare.

4866 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
4867 call to _bfd_generic_link_add_one_symbol.

4873 call to _bfd_generic_link_add_one_symbol.
4874 (ecoff_bfd_final_link): Account for link_order relocs when
4875 allocating space for relocations. Handle them in link_order loop.
4876 (ecoff_link_write_external): Set the storage class of a defined
4877 linker created symbol based on the section it is in. Correct
4878 bfd_link_hash_weak case to use .sc rather than .st.
4879 (ecoff_reloc_link_order): New function.
4880 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4882 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4891 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4893 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4895 * som.c (bfd_section_from_som_symbol): Only to do the value
4896 comparison for function symbols within executables.
4898 * som.c (bfd_section_from_som_symbol): Renamed from
4899 som_section_from_subspace_index. Pass in a native SOM symbol.
4900 For executables, iterate through the sections to find out
4901 which contains the symbol's address rather than using the
4902 symbol_info field. (symbol_info has a different meaning for
4903 dynamicly linked executables.)
4905 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4908 * som.c (som_begin_writing): Fix braino (one call to align
4909 space/subspace data was done unconditionally rather than
4910 just for executables.)
4912 * som.c (som_begin_writing): Align text in all executables to
4913 make HPUX kernel happy. Fixes strip/objcopy for shared
4916 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4918 * som.c (som_begin_writing): Account for alignment needs of
4919 subspaces too when writing executables. Never request a negative
4920 bss size. Fixes some problems with demand paged executables,
4921 still having problems with pure executables and shared executables.
4923 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4925 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4926 bfd_zalloc for rawptr, because later on we may call free, not
4929 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4930 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4931 * cisco-core.c: New file.
4932 * Makefile.in: Change accordingly.
4933 * configure.in: Recognize cisco_core_vec.
4934 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4935 * targets.c: Add cisco_core_vec.
4936 * bfd-in2.h: Rebuilt.
4938 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4940 * som.h (som_copyable_section_data_struct): New structure
4941 containing all the private section information which needs
4942 to be copied from input section to output section during
4944 (som_section_data_struct): Remove several fields now in
4945 som_copyable_section_data_struct. Make the space and
4946 subspace dictionaries be pointers (to save space when
4947 only reading objects).
4949 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4950 some references changed. Allocate a copyable data stucture if
4951 none exists. Store info into the copyable data structure.
4952 (bfd_som_set_subsection_attributes): Likewise.
4953 (som_is_space, som_is_subspace, som_is_container): New functions.
4954 Use these instead of directly accessing private data.
4955 (som_prep_headers): Allocate space and subspace headers here.
4956 Fill in some fields in the space/subspace headers from the
4958 (som_bfd_copy_private_section_data): Only copy the stuff
4959 that we really need to make objcopy and strip work. Allocate
4960 the copy_data structure for the output bfd before copying.
4962 * som.h (struct som_exec_data): New structure to hold exec
4963 info that must be preserved when running objcopy/strip.
4964 (struct somdata): Add new "exec_data" field and accessor
4965 macro. Add some comments on how the various fields are used.
4966 (som_section_data_struct): Make is_space and is_subspace bitfields.
4967 Delete unused subspace_index. All references now use the
4968 target_index field within the section structure itself.
4970 * som.c (make_unique_section): Delete unused declaration.
4971 (som_bfd_copy_private_bfd_data): New function.
4972 (som_object_setup): Allocate space for and save exec information
4973 that needs to be copied during objcopy/strip.
4974 (som_mkobject): Do not allocate space for a file header here.
4975 It is not used when only reading SOM objects.
4976 (som_prep_headers): Allocate space for and attach a file header
4977 to the output bfd. For executables, use the saved system_id
4978 value rather than trying to guess the right value. Do not abort
4979 wwhen setting file_hdr->entry* for executables.
4980 (som_begin_writing): For executables, set the exec_entry and
4982 (som_copy_private_backend_section_data): Always return a value.
4984 * libhppa.h (PA_PAGESIZE): Define.
4986 * som.c (SOM_ALIGN): Define.
4987 (som_begin_writing): If writing an executable, initialize all
4988 fields in the exec header to zero. Update fields in the exec
4989 header as sizes of loadable subspaces are computed. Carefully
4990 preserve alignments when building executables. Actually write the
4991 exec after all the fields are filled in.
4993 * Better long-filename handling. Reads SOM ABI compliant extended
4994 names, but doesn't quite write compliant extended names yet.
4995 * som.c (som_slurp_extended_name_table): Delete function. The
4996 generic code will handle things correctly.
4997 (som_slurp_armap): Seek to the beginning of the next member.
4998 (normalize): New function.
4999 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5000 name table into account when computing the file offsets in the
5001 SOM dictionary. Make sure to align to an even boundary.
5002 (som_write_armap): Initialize the checksum to zero.
5003 (ar_maxchars): Fix. Opps.
5005 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5007 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5008 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5010 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5012 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5013 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5014 * bfd-in2.h: Regenerated.
5016 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5017 this was also named trad_unix_bfd_copy_private_bfd_data.
5019 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5021 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5022 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5023 returns NULL, it is not an error. It's possible that some of
5024 these checks are not necessary (because the size can never be
5025 zero), but putting in the checks is the conservative thing to do
5026 in light of the fact that some of these malloc calls replaced
5027 unchecked alloca calls, in which a zero argument would work fine.
5029 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5031 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5032 duplicate definition.
5033 (osf_core_bfd_is_local_label): Define.
5035 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5036 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5037 failure indication, it merely means there are no relocs.
5039 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5040 after NAME, since SunOS /bin/cc can't handle it.
5042 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5044 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5045 From sukes@glue.umd.edu (Tasuki Hirata).
5047 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5049 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5050 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5051 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5053 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5055 * som.c (som_prep_for_fixups): Detect section symbols based
5056 on either the lack of private data or the symbol flags. Do not
5057 munge section symbol names anymore -- they no longer confuse GDB.
5058 (som_begin_writing): Leave space for an exec header if writing
5060 (som_slurp_symbol_table): Recognize both forms of section symbol
5061 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5062 section symbols to be the name of the section they represent.
5063 Debugging symbols begin with "L$0\001", not just "L$".
5065 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5067 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5069 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5070 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5071 and bfd_is_local_label.
5073 * targets.c: Add new entries to the bfd_target structure.
5075 * bfd.c (bfd_copy_private_bfd_data): New definition.
5077 * section.c (bfd_copy_private_section_data): New definition.
5079 * syms.c (bfd_is_local_label): New definition.
5081 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5083 * libbfd.c (bfd_generic_is_local_label): New function.
5085 * *-core.c: Provide default definitions for new functions in
5086 the target vector which all point to bfd_false.
5088 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5089 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5090 Default new vectors for copying private backend data to bfd_true.
5091 Default new vector for determining if a symbol is a local label
5092 to bfd_generic_is_local_label.
5094 * som.c (som_bfd_copy_private_section_data): New function.
5095 (som_bfd_is_local_label): New function.
5096 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5098 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5100 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5102 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5104 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5107 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5108 Indent some of them to GNU standards.
5110 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5111 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5112 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5113 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5114 Update copyright years.
5116 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5118 * som.c (som_prep_for_fixups): A relocation involving the section
5119 symbol for the *ABS* section is really a relocation involving
5121 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5122 undefined symbols. Correctly distinguish between debugger symbols
5123 and section symbols.
5125 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5126 for spaces and subspaces.
5128 * som.c (som_bfd_count_ar_symbols): Fix typo.
5130 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5131 HAS_RELOC based on the object's magic number.
5132 (make_unique_section): Delete function. BFD and its users are
5133 prepared to handle multiple sections with the same name.
5134 (setup_sections): Allocate space on the BFD's obstack to hold
5135 section names. Use bfd_make_setion_anyway rather than the
5136 obsolete make_unique_section.
5137 (som_prep_headers): Choose the correct SOM magic number based
5139 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5141 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5143 * elf32-ppc.c: Renamed from elf32-powerpc.c.

5153 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5154 is always located at the start of the data section to allow
5155 recovery of the dynamic info from a stripped executable.
5156 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5159 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5161 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5162 cruft (like the #pragma alloca for AIX).
5163 In addition to that problem, the C alloca calls xmalloc, which
5164 means checking for being out of memory can't work right. The
5165 following changes remove all uses of alloca from BFD.
5166 * hosts/solaris2.h: Remove alloca cruft.
5167 * som.c: Replace alloca with a fixed size auto array.

5172 * linker.c: Replace alloca with obstack_alloc.
5173 * libbfd.h: Rebuilt.
5175 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5177 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5180 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5182 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5183 Elf*_Off typedefs by their expansion, the typedefs have been
5184 removed from include/elf/internal.h.
5185 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5186 SHT_PROGBITS section.
5188 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5190 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5194 * configure.host: Recognize i[34]86-sequent-*.
5196 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5197 return from bfd_seek indicates an error.
5198 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5199 TRAD_CORE_STACK_OFFSET.
5200 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5201 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5203 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5205 * som.[ch]: Do not include libhppa.h in som.c, instead include
5208 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5209 include it in elf32-hppa.h.
5211 * som.c (log2): Return -1 on error rather than aborting.
5212 (setup_sections): Bubble up an error from log2.
5214 * Changes to make HP C compiler happy in both traditional
5216 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5218 (bfd_som_set_section_attributes): Use unsigned int rather than
5219 unsigned char to avoid GNU-C extensions.
5220 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5221 or failure rather than aborting on failure.
5223 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5225 (bfd_som_attach_aux_hdr): Add prototype.
5226 (hppa_som-gen_reloc_type): Likewise.

5515 (b_out_relax_section): If a section contains no relocations, don't
5516 bother processing them.
5517 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6220 The sparc (and possibly other?) NLM format requires a different
6221 way to write exports, so add a write_export field to the backend
6222 data (and set it to NULL for everything but the sparc).
