1177 an empty .plt section.
1178 (elf32_sparc_relocate_section): For a GOT reloc against a global
1179 symbol when no dynamic object was seen, initialize the contents of
1180 the .got section. For a GOT reloc against a local symbol, only

1182 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1183 create a PLT entry as a R_SPARC_WDISP30 reloc.

4767 (_bfd_default_link_order): If a reloc_link_order is seen here,
4769 (_bfd_count_link_order_relocs): New function.
4770 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4771 argument from declaration.
4772 (_bfd_generic_reloc_link_order): Declare.
4773 (_bfd_count_link_order_relocs): Declare.
4774 * libbfd.h: Rebuilt.
4775 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
4776 call to _bfd_generic_link_add_one_symbol.
4777 (NAME(aout,final_link)): Account for link_order relocs when
4778 allocating space for relocations. Handle them after handling all
4780 (aout_link_reloc_link_order): New function.
4781 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
4782 call to _bfd_generic_link_add_one_symbol.
4783 (ecoff_bfd_final_link): Account for link_order relocs when
4784 allocating space for relocations. Handle them in link_order loop.
4785 (ecoff_link_write_external): Set the storage class of a defined
4786 linker created symbol based on the section it is in. Correct
4787 bfd_link_hash_weak case to use .sc rather than .st.
4788 (ecoff_reloc_link_order): New function.
4789 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4791 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4793 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4796 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4797 bfd_zmalloc. Free a pointer, not a union.
4798 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4800 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4802 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4804 * som.c (bfd_section_from_som_symbol): Only to do the value
4805 comparison for function symbols within executables.
4807 * som.c (bfd_section_from_som_symbol): Renamed from
4808 som_section_from_subspace_index. Pass in a native SOM symbol.
4809 For executables, iterate through the sections to find out
4810 which contains the symbol's address rather than using the
4811 symbol_info field. (symbol_info has a different meaning for
4812 dynamicly linked executables.)
4814 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4817 * som.c (som_begin_writing): Fix braino (one call to align
4818 space/subspace data was done unconditionally rather than
4819 just for executables.)
4821 * som.c (som_begin_writing): Align text in all executables to
4822 make HPUX kernel happy. Fixes strip/objcopy for shared
4825 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4827 * som.c (som_begin_writing): Account for alignment needs of
4828 subspaces too when writing executables. Never request a negative
4829 bss size. Fixes some problems with demand paged executables,
4830 still having problems with pure executables and shared executables.
4832 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4834 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4835 bfd_zalloc for rawptr, because later on we may call free, not
4838 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4839 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4840 * cisco-core.c: New file.
4841 * Makefile.in: Change accordingly.
4842 * configure.in: Recognize cisco_core_vec.
4843 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4844 * targets.c: Add cisco_core_vec.
4845 * bfd-in2.h: Rebuilt.
4847 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4849 * som.h (som_copyable_section_data_struct): New structure
4850 containing all the private section information which needs
4851 to be copied from input section to output section during
4853 (som_section_data_struct): Remove several fields now in
4854 som_copyable_section_data_struct. Make the space and
4855 subspace dictionaries be pointers (to save space when
4856 only reading objects).
4858 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4859 some references changed. Allocate a copyable data stucture if
4860 none exists. Store info into the copyable data structure.
4861 (bfd_som_set_subsection_attributes): Likewise.
4862 (som_is_space, som_is_subspace, som_is_container): New functions.
4863 Use these instead of directly accessing private data.
4864 (som_prep_headers): Allocate space and subspace headers here.
4865 Fill in some fields in the space/subspace headers from the
4867 (som_bfd_copy_private_section_data): Only copy the stuff
4868 that we really need to make objcopy and strip work. Allocate
4869 the copy_data structure for the output bfd before copying.
4871 * som.h (struct som_exec_data): New structure to hold exec
4872 info that must be preserved when running objcopy/strip.
4873 (struct somdata): Add new "exec_data" field and accessor
4874 macro. Add some comments on how the various fields are used.
4875 (som_section_data_struct): Make is_space and is_subspace bitfields.
4876 Delete unused subspace_index. All references now use the
4877 target_index field within the section structure itself.
4879 * som.c (make_unique_section): Delete unused declaration.
4880 (som_bfd_copy_private_bfd_data): New function.
4881 (som_object_setup): Allocate space for and save exec information
4882 that needs to be copied during objcopy/strip.
4883 (som_mkobject): Do not allocate space for a file header here.
4884 It is not used when only reading SOM objects.
4885 (som_prep_headers): Allocate space for and attach a file header
4886 to the output bfd. For executables, use the saved system_id
4887 value rather than trying to guess the right value. Do not abort
4888 wwhen setting file_hdr->entry* for executables.
4889 (som_begin_writing): For executables, set the exec_entry and
4891 (som_copy_private_backend_section_data): Always return a value.
4893 * libhppa.h (PA_PAGESIZE): Define.
4895 * som.c (SOM_ALIGN): Define.
4896 (som_begin_writing): If writing an executable, initialize all
4897 fields in the exec header to zero. Update fields in the exec
4898 header as sizes of loadable subspaces are computed. Carefully
4899 preserve alignments when building executables. Actually write the
4900 exec after all the fields are filled in.
4902 * Better long-filename handling. Reads SOM ABI compliant extended
4903 names, but doesn't quite write compliant extended names yet.
4904 * som.c (som_slurp_extended_name_table): Delete function. The
4905 generic code will handle things correctly.
4906 (som_slurp_armap): Seek to the beginning of the next member.
4907 (normalize): New function.
4908 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4909 name table into account when computing the file offsets in the
4910 SOM dictionary. Make sure to align to an even boundary.
4911 (som_write_armap): Initialize the checksum to zero.
4912 (ar_maxchars): Fix. Opps.
4914 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4916 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4917 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4919 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4921 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4922 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4923 * bfd-in2.h: Regenerated.
4925 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4926 this was also named trad_unix_bfd_copy_private_bfd_data.
4928 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4930 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4931 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4932 returns NULL, it is not an error. It's possible that some of
4933 these checks are not necessary (because the size can never be
4934 zero), but putting in the checks is the conservative thing to do
4935 in light of the fact that some of these malloc calls replaced
4936 unchecked alloca calls, in which a zero argument would work fine.
4938 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4940 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4941 duplicate definition.
4942 (osf_core_bfd_is_local_label): Define.
4944 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4945 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4946 failure indication, it merely means there are no relocs.
4948 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4949 after NAME, since SunOS /bin/cc can't handle it.
4951 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4953 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4954 From sukes@glue.umd.edu (Tasuki Hirata).
4956 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4958 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4959 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4960 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4962 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4964 * som.c (som_prep_for_fixups): Detect section symbols based
4965 on either the lack of private data or the symbol flags. Do not
4966 munge section symbol names anymore -- they no longer confuse GDB.
4967 (som_begin_writing): Leave space for an exec header if writing
4969 (som_slurp_symbol_table): Recognize both forms of section symbol
4970 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4971 section symbols to be the name of the section they represent.
4972 Debugging symbols begin with "L$0\001", not just "L$".
4974 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4976 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4978 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4979 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4980 and bfd_is_local_label.
4982 * targets.c: Add new entries to the bfd_target structure.
4984 * bfd.c (bfd_copy_private_bfd_data): New definition.
4986 * section.c (bfd_copy_private_section_data): New definition.
4988 * syms.c (bfd_is_local_label): New definition.
4990 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4992 * libbfd.c (bfd_generic_is_local_label): New function.
4994 * *-core.c: Provide default definitions for new functions in
4995 the target vector which all point to bfd_false.
4997 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4998 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4999 Default new vectors for copying private backend data to bfd_true.
5000 Default new vector for determining if a symbol is a local label
5001 to bfd_generic_is_local_label.
5003 * som.c (som_bfd_copy_private_section_data): New function.
5004 (som_bfd_is_local_label): New function.
5005 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5007 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5009 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5011 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5013 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5016 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5017 Indent some of them to GNU standards.
5019 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5020 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5021 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5022 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5023 Update copyright years.
5025 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5027 * som.c (som_prep_for_fixups): A relocation involving the section
5028 symbol for the *ABS* section is really a relocation involving
5030 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5031 undefined symbols. Correctly distinguish between debugger symbols
5032 and section symbols.
5034 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5035 for spaces and subspaces.
5037 * som.c (som_bfd_count_ar_symbols): Fix typo.
5039 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5040 HAS_RELOC based on the object's magic number.
5041 (make_unique_section): Delete function. BFD and its users are
5042 prepared to handle multiple sections with the same name.
5043 (setup_sections): Allocate space on the BFD's obstack to hold
5044 section names. Use bfd_make_setion_anyway rather than the
5045 obsolete make_unique_section.
5046 (som_prep_headers): Choose the correct SOM magic number based
5048 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5050 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5052 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5053 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5054 * Makefile.in, configure.in: Corresponding changes.
5056 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5058 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5060 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5062 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5063 is always located at the start of the data section to allow
5064 recovery of the dynamic info from a stripped executable.
5065 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5068 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5070 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5071 cruft (like the #pragma alloca for AIX).
5072 In addition to that problem, the C alloca calls xmalloc, which
5073 means checking for being out of memory can't work right. The
5074 following changes remove all uses of alloca from BFD.
5075 * hosts/solaris2.h: Remove alloca cruft.
5076 * som.c: Replace alloca with a fixed size auto array.
5077 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5078 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5079 sunos.c: Replace alloca with malloc and appropriate error checking and
5081 * linker.c: Replace alloca with obstack_alloc.
5082 * libbfd.h: Rebuilt.
5084 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5086 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5089 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5091 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5092 Elf*_Off typedefs by their expansion, the typedefs have been
5093 removed from include/elf/internal.h.
5094 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5095 SHT_PROGBITS section.
5097 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5099 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5103 * configure.host: Recognize i[34]86-sequent-*.
5105 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5106 return from bfd_seek indicates an error.
5107 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5108 TRAD_CORE_STACK_OFFSET.
5109 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5110 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5112 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5114 * som.[ch]: Do not include libhppa.h in som.c, instead include
5117 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5118 include it in elf32-hppa.h.
5120 * som.c (log2): Return -1 on error rather than aborting.
5121 (setup_sections): Bubble up an error from log2.
5123 * Changes to make HP C compiler happy in both traditional
5125 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5127 (bfd_som_set_section_attributes): Use unsigned int rather than
5128 unsigned char to avoid GNU-C extensions.
5129 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5130 or failure rather than aborting on failure.
5132 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5134 (bfd_som_attach_aux_hdr): Add prototype.
5135 (hppa_som-gen_reloc_type): Likewise.
5137 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5138 (hppa_look_for_stubs_in_section): Do not return false on failure
5139 until rest of code is ready to handle it. Abort for now.
5141 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5143 * bfd-in2.h: Rebuilt.
5145 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

5151 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
5153 * config.bfd : Add i386-os9k.
5154 * config/i386-os9k.mt : Newly add os9k target makefile.
5156 * i386os9k.c : new file to handle os9k format bfd.
5157 * Makefile.in : Handle new file i386os9k.c
5158 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
5159 * cache.c : Initialize cache_sentinel to 0.
5161 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5163 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5164 action in case where caller specified no argument relocation.
5165 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5166 right in the original relocation and the stub's relocation.
5168 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5169 unused symbols argument.
5171 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5172 than asymbol * for original target symbol. All callers changed.
5173 Set reloc->sym_ptr_ptr appropriately.
5174 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5175 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5176 argument. Use the output symbols when canonicalizing the relocs,
5177 creating them if necessary.
5179 * linker.c (_bfd_generic_link_output_symbols): Do not
5180 rebuild/clobber the output symbols if they already exist.
5182 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5184 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5185 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5186 * bfd-in2.h: Rebuilt.
5188 * srec.c (hex_value): Always set to a size of 256 bytes.
5189 (srec_init): Cosmetic changes.
5191 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5193 * elf32-hppa.c: Second half of major cleanup. More comments,
5194 PARAMize and staticize rest of functions. Delete unused
5195 functions. Delete unused/unnecessary arguments to some functions.
5196 Group static vars together. Abort for bad errors until we have
5197 error code propogation working. Work on spacing and indention.
5198 Add FIXMEs for unresolved problems. Use enums rather than
5199 #defines for lots of things. Merge two functions which build
5200 linker stubs into a single function (so they can easily share a
5201 ton of common code).
5203 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5205 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5206 avoid depending upon right shifts of signed numbers, and to
5207 correct handling of src_mask with lower bits zero.
5209 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5210 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
5211 * elf32-i386.c: Likewise.
5212 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old

6129 The sparc (and possibly other?) NLM format requires a different
6130 way to write exports, so add a write_export field to the backend
6131 data (and set it to NULL for everything but the sparc).

7415 terms of MY, because that causes a recusive invocation of CAT when
7416 expanded within JUMP_TABLE, and ANSI compilers don't expand
7418 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
7419 MY_reloc_howto_type_lookup, and don't define in terms of MY.
7420 (MY_canonicalize_reloc): Don't define in terms of MY.
7421 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
7422 than listing functions.
