1154 an empty .plt section.
1155 (elf32_sparc_relocate_section): For a GOT reloc against a global
1156 symbol when no dynamic object was seen, initialize the contents of
1157 the .got section. For a GOT reloc against a local symbol, only

4764 bfd_link_hash_weak case to use .sc rather than .st.
4765 (ecoff_reloc_link_order): New function.
4766 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4768 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4770 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4773 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4774 bfd_zmalloc. Free a pointer, not a union.
4775 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4777 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4779 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4781 * som.c (bfd_section_from_som_symbol): Only to do the value
4782 comparison for function symbols within executables.
4784 * som.c (bfd_section_from_som_symbol): Renamed from
4785 som_section_from_subspace_index. Pass in a native SOM symbol.
4786 For executables, iterate through the sections to find out
4787 which contains the symbol's address rather than using the
4788 symbol_info field. (symbol_info has a different meaning for
4789 dynamicly linked executables.)
4791 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4794 * som.c (som_begin_writing): Fix braino (one call to align
4795 space/subspace data was done unconditionally rather than
4796 just for executables.)
4798 * som.c (som_begin_writing): Align text in all executables to
4799 make HPUX kernel happy. Fixes strip/objcopy for shared
4802 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4804 * som.c (som_begin_writing): Account for alignment needs of
4805 subspaces too when writing executables. Never request a negative
4806 bss size. Fixes some problems with demand paged executables,
4807 still having problems with pure executables and shared executables.
4809 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4811 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4812 bfd_zalloc for rawptr, because later on we may call free, not
4815 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4816 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4817 * cisco-core.c: New file.
4818 * Makefile.in: Change accordingly.
4819 * configure.in: Recognize cisco_core_vec.
4820 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4821 * targets.c: Add cisco_core_vec.
4822 * bfd-in2.h: Rebuilt.
4824 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4826 * som.h (som_copyable_section_data_struct): New structure
4827 containing all the private section information which needs
4828 to be copied from input section to output section during
4830 (som_section_data_struct): Remove several fields now in
4831 som_copyable_section_data_struct. Make the space and
4832 subspace dictionaries be pointers (to save space when
4833 only reading objects).
4835 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4836 some references changed. Allocate a copyable data stucture if
4837 none exists. Store info into the copyable data structure.
4838 (bfd_som_set_subsection_attributes): Likewise.
4839 (som_is_space, som_is_subspace, som_is_container): New functions.
4840 Use these instead of directly accessing private data.
4841 (som_prep_headers): Allocate space and subspace headers here.
4842 Fill in some fields in the space/subspace headers from the
4844 (som_bfd_copy_private_section_data): Only copy the stuff
4845 that we really need to make objcopy and strip work. Allocate
4846 the copy_data structure for the output bfd before copying.
4848 * som.h (struct som_exec_data): New structure to hold exec
4849 info that must be preserved when running objcopy/strip.
4850 (struct somdata): Add new "exec_data" field and accessor
4851 macro. Add some comments on how the various fields are used.
4852 (som_section_data_struct): Make is_space and is_subspace bitfields.
4853 Delete unused subspace_index. All references now use the
4854 target_index field within the section structure itself.
4856 * som.c (make_unique_section): Delete unused declaration.
4857 (som_bfd_copy_private_bfd_data): New function.
4858 (som_object_setup): Allocate space for and save exec information
4859 that needs to be copied during objcopy/strip.
4860 (som_mkobject): Do not allocate space for a file header here.
4861 It is not used when only reading SOM objects.
4862 (som_prep_headers): Allocate space for and attach a file header
4863 to the output bfd. For executables, use the saved system_id
4864 value rather than trying to guess the right value. Do not abort
4865 wwhen setting file_hdr->entry* for executables.
4866 (som_begin_writing): For executables, set the exec_entry and
4868 (som_copy_private_backend_section_data): Always return a value.
4870 * libhppa.h (PA_PAGESIZE): Define.
4872 * som.c (SOM_ALIGN): Define.
4873 (som_begin_writing): If writing an executable, initialize all
4874 fields in the exec header to zero. Update fields in the exec
4875 header as sizes of loadable subspaces are computed. Carefully
4876 preserve alignments when building executables. Actually write the
4877 exec after all the fields are filled in.
4879 * Better long-filename handling. Reads SOM ABI compliant extended
4880 names, but doesn't quite write compliant extended names yet.
4881 * som.c (som_slurp_extended_name_table): Delete function. The
4882 generic code will handle things correctly.
4883 (som_slurp_armap): Seek to the beginning of the next member.
4884 (normalize): New function.
4885 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4886 name table into account when computing the file offsets in the
4887 SOM dictionary. Make sure to align to an even boundary.
4888 (som_write_armap): Initialize the checksum to zero.
4889 (ar_maxchars): Fix. Opps.
4891 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4893 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4894 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4896 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4898 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4899 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4900 * bfd-in2.h: Regenerated.
4902 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4903 this was also named trad_unix_bfd_copy_private_bfd_data.
4905 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4907 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4908 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4909 returns NULL, it is not an error. It's possible that some of
4910 these checks are not necessary (because the size can never be
4911 zero), but putting in the checks is the conservative thing to do
4912 in light of the fact that some of these malloc calls replaced
4913 unchecked alloca calls, in which a zero argument would work fine.
4915 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4917 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4918 duplicate definition.
4919 (osf_core_bfd_is_local_label): Define.
4921 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4922 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4923 failure indication, it merely means there are no relocs.
4925 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4926 after NAME, since SunOS /bin/cc can't handle it.
4928 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4930 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4931 From sukes@glue.umd.edu (Tasuki Hirata).
4933 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4935 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4936 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4937 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4939 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4941 * som.c (som_prep_for_fixups): Detect section symbols based
4942 on either the lack of private data or the symbol flags. Do not
4943 munge section symbol names anymore -- they no longer confuse GDB.
4944 (som_begin_writing): Leave space for an exec header if writing
4946 (som_slurp_symbol_table): Recognize both forms of section symbol
4947 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4948 section symbols to be the name of the section they represent.
4949 Debugging symbols begin with "L$0\001", not just "L$".
4951 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4953 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4955 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4956 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4957 and bfd_is_local_label.
4959 * targets.c: Add new entries to the bfd_target structure.
4961 * bfd.c (bfd_copy_private_bfd_data): New definition.
4963 * section.c (bfd_copy_private_section_data): New definition.
4965 * syms.c (bfd_is_local_label): New definition.
4967 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4969 * libbfd.c (bfd_generic_is_local_label): New function.
4971 * *-core.c: Provide default definitions for new functions in
4972 the target vector which all point to bfd_false.
4974 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4975 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4976 Default new vectors for copying private backend data to bfd_true.
4977 Default new vector for determining if a symbol is a local label
4978 to bfd_generic_is_local_label.
4980 * som.c (som_bfd_copy_private_section_data): New function.
4981 (som_bfd_is_local_label): New function.
4982 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4984 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4986 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4988 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4990 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4993 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4994 Indent some of them to GNU standards.
4996 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4997 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4998 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4999 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5000 Update copyright years.
5002 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5004 * som.c (som_prep_for_fixups): A relocation involving the section
5005 symbol for the *ABS* section is really a relocation involving
5007 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5008 undefined symbols. Correctly distinguish between debugger symbols
5009 and section symbols.
5011 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5012 for spaces and subspaces.
5014 * som.c (som_bfd_count_ar_symbols): Fix typo.
5016 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5017 HAS_RELOC based on the object's magic number.
5018 (make_unique_section): Delete function. BFD and its users are
5019 prepared to handle multiple sections with the same name.
5020 (setup_sections): Allocate space on the BFD's obstack to hold
5021 section names. Use bfd_make_setion_anyway rather than the
5022 obsolete make_unique_section.
5023 (som_prep_headers): Choose the correct SOM magic number based
5025 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5027 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5029 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5030 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5031 * Makefile.in, configure.in: Corresponding changes.
5033 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5035 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5037 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5039 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5040 is always located at the start of the data section to allow
5041 recovery of the dynamic info from a stripped executable.
5042 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5045 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5047 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5048 cruft (like the #pragma alloca for AIX).
5049 In addition to that problem, the C alloca calls xmalloc, which
5050 means checking for being out of memory can't work right. The
5051 following changes remove all uses of alloca from BFD.
5052 * hosts/solaris2.h: Remove alloca cruft.
5053 * som.c: Replace alloca with a fixed size auto array.
5054 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5055 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5056 sunos.c: Replace alloca with malloc and appropriate error checking and
5058 * linker.c: Replace alloca with obstack_alloc.
5059 * libbfd.h: Rebuilt.
5061 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5063 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5066 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5068 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5069 Elf*_Off typedefs by their expansion, the typedefs have been
5070 removed from include/elf/internal.h.
5071 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5072 SHT_PROGBITS section.
5074 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5076 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5082 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5083 return from bfd_seek indicates an error.
5084 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5085 TRAD_CORE_STACK_OFFSET.
5086 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5087 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5089 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5091 * som.[ch]: Do not include libhppa.h in som.c, instead include
5094 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5095 include it in elf32-hppa.h.
5097 * som.c (log2): Return -1 on error rather than aborting.
5098 (setup_sections): Bubble up an error from log2.
5100 * Changes to make HP C compiler happy in both traditional
5102 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5104 (bfd_som_set_section_attributes): Use unsigned int rather than
5105 unsigned char to avoid GNU-C extensions.
5106 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5107 or failure rather than aborting on failure.
5109 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5111 (bfd_som_attach_aux_hdr): Add prototype.
5112 (hppa_som-gen_reloc_type): Likewise.
5114 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5115 (hppa_look_for_stubs_in_section): Do not return false on failure
5116 until rest of code is ready to handle it. Abort for now.

5120 * bfd-in2.h: Rebuilt.
5122 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

5128 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
5130 * config.bfd : Add i386-os9k.
5131 * config/i386-os9k.mt : Newly add os9k target makefile.
5133 * i386os9k.c : new file to handle os9k format bfd.
5134 * Makefile.in : Handle new file i386os9k.c
5135 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
5136 * cache.c : Initialize cache_sentinel to 0.

5140 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5141 action in case where caller specified no argument relocation.
5142 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5143 right in the original relocation and the stub's relocation.
5145 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5146 unused symbols argument.
5148 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5149 than asymbol * for original target symbol. All callers changed.
5150 Set reloc->sym_ptr_ptr appropriately.
5151 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5152 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5153 argument. Use the output symbols when canonicalizing the relocs,
5154 creating them if necessary.
5156 * linker.c (_bfd_generic_link_output_symbols): Do not
5157 rebuild/clobber the output symbols if they already exist.
5159 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5161 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5162 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5163 * bfd-in2.h: Rebuilt.
5165 * srec.c (hex_value): Always set to a size of 256 bytes.
5166 (srec_init): Cosmetic changes.
5168 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5170 * elf32-hppa.c: Second half of major cleanup. More comments,
5171 PARAMize and staticize rest of functions. Delete unused
5172 functions. Delete unused/unnecessary arguments to some functions.
5173 Group static vars together. Abort for bad errors until we have
5174 error code propogation working. Work on spacing and indention.
5175 Add FIXMEs for unresolved problems. Use enums rather than
5176 #defines for lots of things. Merge two functions which build
5177 linker stubs into a single function (so they can easily share a
5178 ton of common code).
5180 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5182 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5183 avoid depending upon right shifts of signed numbers, and to
5184 correct handling of src_mask with lower bits zero.
5186 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5187 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

5194 (write_shdrs_and_ehdr): Make count unsigned.
5195 (assign_file_positions_for_relocs): Make i unsigned.
5196 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
5197 (section_from_elf_index): Make index argument unsigned.
5199 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
5201 * elfcode.h: Don't include assert.h.

5207 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
5210 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5212 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
5214 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5215 (elf_hppa_tc_make_sections): Likewise.
5216 (elf_hppa_final_processing): Add extern decl.
5218 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5219 comments. PARAMize some static functions. Delete unused functions.
5220 Delete unused/unnecessary arguments to many functions. Group
5221 static vars together. Collapse common case statements together
5222 in many places. Use default case when possible instead of listing

6076 use get_value to get the symbol value and check for undefined
6078 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6079 undefined, look it up in the linker hash table.
6081 * aoutx.h (translate_symbol_table): The string index 0 has a

6106 The sparc (and possibly other?) NLM format requires a different
6107 way to write exports, so add a write_export field to the backend
