4764 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4766 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4768 * som.c (bfd_section_from_som_symbol): Only to do the value
4769 comparison for function symbols within executables.
4771 * som.c (bfd_section_from_som_symbol): Renamed from
4772 som_section_from_subspace_index. Pass in a native SOM symbol.
4773 For executables, iterate through the sections to find out
4774 which contains the symbol's address rather than using the
4775 symbol_info field. (symbol_info has a different meaning for
4776 dynamicly linked executables.)
4778 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4781 * som.c (som_begin_writing): Fix braino (one call to align
4782 space/subspace data was done unconditionally rather than
4783 just for executables.)
4785 * som.c (som_begin_writing): Align text in all executables to
4786 make HPUX kernel happy. Fixes strip/objcopy for shared
4789 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4791 * som.c (som_begin_writing): Account for alignment needs of
4792 subspaces too when writing executables. Never request a negative
4793 bss size. Fixes some problems with demand paged executables,
4794 still having problems with pure executables and shared executables.
4796 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4798 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4799 bfd_zalloc for rawptr, because later on we may call free, not
4802 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4803 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4804 * cisco-core.c: New file.
4805 * Makefile.in: Change accordingly.
4806 * configure.in: Recognize cisco_core_vec.
4807 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4808 * targets.c: Add cisco_core_vec.
4809 * bfd-in2.h: Rebuilt.
4811 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4813 * som.h (som_copyable_section_data_struct): New structure
4814 containing all the private section information which needs
4815 to be copied from input section to output section during
4817 (som_section_data_struct): Remove several fields now in
4818 som_copyable_section_data_struct. Make the space and
4819 subspace dictionaries be pointers (to save space when
4820 only reading objects).
4822 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4823 some references changed. Allocate a copyable data stucture if
4824 none exists. Store info into the copyable data structure.
4825 (bfd_som_set_subsection_attributes): Likewise.
4826 (som_is_space, som_is_subspace, som_is_container): New functions.
4827 Use these instead of directly accessing private data.
4828 (som_prep_headers): Allocate space and subspace headers here.
4829 Fill in some fields in the space/subspace headers from the
4831 (som_bfd_copy_private_section_data): Only copy the stuff
4832 that we really need to make objcopy and strip work. Allocate
4833 the copy_data structure for the output bfd before copying.
4835 * som.h (struct som_exec_data): New structure to hold exec
4836 info that must be preserved when running objcopy/strip.
4837 (struct somdata): Add new "exec_data" field and accessor
4838 macro. Add some comments on how the various fields are used.
4839 (som_section_data_struct): Make is_space and is_subspace bitfields.
4840 Delete unused subspace_index. All references now use the
4841 target_index field within the section structure itself.
4843 * som.c (make_unique_section): Delete unused declaration.
4844 (som_bfd_copy_private_bfd_data): New function.
4845 (som_object_setup): Allocate space for and save exec information
4846 that needs to be copied during objcopy/strip.
4847 (som_mkobject): Do not allocate space for a file header here.
4848 It is not used when only reading SOM objects.
4849 (som_prep_headers): Allocate space for and attach a file header
4850 to the output bfd. For executables, use the saved system_id
4851 value rather than trying to guess the right value. Do not abort
4852 wwhen setting file_hdr->entry* for executables.
4853 (som_begin_writing): For executables, set the exec_entry and
4855 (som_copy_private_backend_section_data): Always return a value.
4857 * libhppa.h (PA_PAGESIZE): Define.
4859 * som.c (SOM_ALIGN): Define.
4860 (som_begin_writing): If writing an executable, initialize all
4861 fields in the exec header to zero. Update fields in the exec
4862 header as sizes of loadable subspaces are computed. Carefully
4863 preserve alignments when building executables. Actually write the
4864 exec after all the fields are filled in.
4866 * Better long-filename handling. Reads SOM ABI compliant extended
4867 names, but doesn't quite write compliant extended names yet.
4868 * som.c (som_slurp_extended_name_table): Delete function. The
4869 generic code will handle things correctly.
4870 (som_slurp_armap): Seek to the beginning of the next member.
4871 (normalize): New function.
4872 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4873 name table into account when computing the file offsets in the
4874 SOM dictionary. Make sure to align to an even boundary.
4875 (som_write_armap): Initialize the checksum to zero.
4876 (ar_maxchars): Fix. Opps.
4878 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4880 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4881 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4883 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4885 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4886 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4887 * bfd-in2.h: Regenerated.
4889 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4890 this was also named trad_unix_bfd_copy_private_bfd_data.
4892 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4894 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4895 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4896 returns NULL, it is not an error. It's possible that some of
4897 these checks are not necessary (because the size can never be
4898 zero), but putting in the checks is the conservative thing to do
4899 in light of the fact that some of these malloc calls replaced
4900 unchecked alloca calls, in which a zero argument would work fine.
4902 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4904 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4905 duplicate definition.
4906 (osf_core_bfd_is_local_label): Define.
4908 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4909 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4910 failure indication, it merely means there are no relocs.
4912 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4913 after NAME, since SunOS /bin/cc can't handle it.
4915 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4917 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4918 From sukes@glue.umd.edu (Tasuki Hirata).
4920 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4922 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4923 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4924 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4926 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4928 * som.c (som_prep_for_fixups): Detect section symbols based
4929 on either the lack of private data or the symbol flags. Do not
4930 munge section symbol names anymore -- they no longer confuse GDB.
4931 (som_begin_writing): Leave space for an exec header if writing
4933 (som_slurp_symbol_table): Recognize both forms of section symbol
4934 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4935 section symbols to be the name of the section they represent.
4936 Debugging symbols begin with "L$0\001", not just "L$".
4938 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4940 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4942 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4943 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4944 and bfd_is_local_label.
4946 * targets.c: Add new entries to the bfd_target structure.
4948 * bfd.c (bfd_copy_private_bfd_data): New definition.
4950 * section.c (bfd_copy_private_section_data): New definition.
4952 * syms.c (bfd_is_local_label): New definition.
4954 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4956 * libbfd.c (bfd_generic_is_local_label): New function.
4958 * *-core.c: Provide default definitions for new functions in
4959 the target vector which all point to bfd_false.
4961 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4962 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4963 Default new vectors for copying private backend data to bfd_true.
4964 Default new vector for determining if a symbol is a local label
4965 to bfd_generic_is_local_label.
4967 * som.c (som_bfd_copy_private_section_data): New function.
4968 (som_bfd_is_local_label): New function.
4969 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4971 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4973 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4975 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4977 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4980 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4981 Indent some of them to GNU standards.
4983 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4984 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4985 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4986 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4987 Update copyright years.
4989 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4991 * som.c (som_prep_for_fixups): A relocation involving the section
4992 symbol for the *ABS* section is really a relocation involving
4994 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4995 undefined symbols. Correctly distinguish between debugger symbols
4996 and section symbols.
4998 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4999 for spaces and subspaces.
5001 * som.c (som_bfd_count_ar_symbols): Fix typo.
5003 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5004 HAS_RELOC based on the object's magic number.
5005 (make_unique_section): Delete function. BFD and its users are
5006 prepared to handle multiple sections with the same name.
5007 (setup_sections): Allocate space on the BFD's obstack to hold
5008 section names. Use bfd_make_setion_anyway rather than the
5009 obsolete make_unique_section.
5010 (som_prep_headers): Choose the correct SOM magic number based
5012 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5014 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5016 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5017 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5018 * Makefile.in, configure.in: Corresponding changes.
5020 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5022 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5024 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5026 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5027 is always located at the start of the data section to allow
5028 recovery of the dynamic info from a stripped executable.
5029 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5032 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5034 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5035 cruft (like the #pragma alloca for AIX).
5036 In addition to that problem, the C alloca calls xmalloc, which
5037 means checking for being out of memory can't work right. The
5038 following changes remove all uses of alloca from BFD.
5039 * hosts/solaris2.h: Remove alloca cruft.
5040 * som.c: Replace alloca with a fixed size auto array.
5041 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5042 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5043 sunos.c: Replace alloca with malloc and appropriate error checking and
5045 * linker.c: Replace alloca with obstack_alloc.
5046 * libbfd.h: Rebuilt.
5048 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5050 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5053 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5055 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5056 Elf*_Off typedefs by their expansion, the typedefs have been
5057 removed from include/elf/internal.h.
5058 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5059 SHT_PROGBITS section.
5061 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5063 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5067 * configure.host: Recognize i[34]86-sequent-*.
5069 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5070 return from bfd_seek indicates an error.
5071 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5072 TRAD_CORE_STACK_OFFSET.
5073 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5074 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5076 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5078 * som.[ch]: Do not include libhppa.h in som.c, instead include
5081 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5082 include it in elf32-hppa.h.
5084 * som.c (log2): Return -1 on error rather than aborting.
5085 (setup_sections): Bubble up an error from log2.
5087 * Changes to make HP C compiler happy in both traditional
5089 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5091 (bfd_som_set_section_attributes): Use unsigned int rather than
5092 unsigned char to avoid GNU-C extensions.
5093 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5094 or failure rather than aborting on failure.
5096 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5098 (bfd_som_attach_aux_hdr): Add prototype.
5099 (hppa_som-gen_reloc_type): Likewise.
5101 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5102 (hppa_look_for_stubs_in_section): Do not return false on failure
5103 until rest of code is ready to handle it. Abort for now.
5105 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5107 * bfd-in2.h: Rebuilt.
5109 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
5111 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

5115 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
5117 * config.bfd : Add i386-os9k.
5118 * config/i386-os9k.mt : Newly add os9k target makefile.
5120 * i386os9k.c : new file to handle os9k format bfd.
5121 * Makefile.in : Handle new file i386os9k.c
5122 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
5123 * cache.c : Initialize cache_sentinel to 0.

5127 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5128 action in case where caller specified no argument relocation.
5129 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5130 right in the original relocation and the stub's relocation.
5132 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5133 unused symbols argument.
5135 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5136 than asymbol * for original target symbol. All callers changed.
5137 Set reloc->sym_ptr_ptr appropriately.
5138 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5139 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5140 argument. Use the output symbols when canonicalizing the relocs,
5141 creating them if necessary.
5143 * linker.c (_bfd_generic_link_output_symbols): Do not
5144 rebuild/clobber the output symbols if they already exist.
5146 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5148 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5149 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5150 * bfd-in2.h: Rebuilt.
5152 * srec.c (hex_value): Always set to a size of 256 bytes.
5153 (srec_init): Cosmetic changes.
5155 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5157 * elf32-hppa.c: Second half of major cleanup. More comments,
5158 PARAMize and staticize rest of functions. Delete unused
5159 functions. Delete unused/unnecessary arguments to some functions.
5160 Group static vars together. Abort for bad errors until we have
5161 error code propogation working. Work on spacing and indention.
5162 Add FIXMEs for unresolved problems. Use enums rather than
5163 #defines for lots of things. Merge two functions which build
5164 linker stubs into a single function (so they can easily share a
5165 ton of common code).
5167 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5169 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5170 avoid depending upon right shifts of signed numbers, and to
5171 correct handling of src_mask with lower bits zero.
5173 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5174 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
5175 * elf32-i386.c: Likewise.

5180 (assign_file_positions_except_relocs): Make i unsigned.
5181 (write_shdrs_and_ehdr): Make count unsigned.
5182 (assign_file_positions_for_relocs): Make i unsigned.
5183 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
5184 (section_from_elf_index): Make index argument unsigned.
5186 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
5188 * elfcode.h: Don't include assert.h.
5189 (swap_out_syms): Use BFD_ASSERT rather than assert.
5191 * linker.c (_bfd_generic_link_write_global_symbol): Add missing
5194 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
5197 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5199 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
5201 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5202 (elf_hppa_tc_make_sections): Likewise.
5203 (elf_hppa_final_processing): Add extern decl.
5205 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5206 comments. PARAMize some static functions. Delete unused functions.
5207 Delete unused/unnecessary arguments to many functions. Group
5208 static vars together. Collapse common case statements together
5209 in many places. Use default case when possible instead of listing
5210 each case separately. Abort for bad errors until we get error
5211 code propogation working. Work on spacing and indention problems.
5212 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5213 COMPLEX relocation support (it's never used anyway).
5214 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5215 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5216 (elf_hppa_tc_make_sections): Likewise.
5218 * format.c (bfd_check_format_matches): Initialize matching_vector

6059 the symbol value and check for undefined symbols.
6060 (get_value): If the symbol is undefined, look it up in the linker
6062 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6063 use get_value to get the symbol value and check for undefined
6065 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6066 undefined, look it up in the linker hash table.
6068 * aoutx.h (translate_symbol_table): The string index 0 has a

6093 The sparc (and possibly other?) NLM format requires a different
6094 way to write exports, so add a write_export field to the backend
6095 data (and set it to NULL for everything but the sparc).
