4762 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4764 * som.h (som_copyable_section_data_struct): New structure
4765 containing all the private section information which needs
4766 to be copied from input section to output section during
4768 (som_section_data_struct): Remove several fields now in
4769 som_copyable_section_data_struct. Make the space and
4770 subspace dictionaries be pointers (to save space when
4771 only reading objects).
4773 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4774 some references changed. Allocate a copyable data stucture if
4775 none exists. Store info into the copyable data structure.
4776 (bfd_som_set_subsection_attributes): Likewise.
4777 (som_is_space, som_is_subspace, som_is_container): New functions.
4778 Use these instead of directly accessing private data.
4779 (som_prep_headers): Allocate space and subspace headers here.
4780 Fill in some fields in the space/subspace headers from the
4782 (som_bfd_copy_private_section_data): Only copy the stuff
4783 that we really need to make objcopy and strip work. Allocate
4784 the copy_data structure for the output bfd before copying.
4786 * som.h (struct som_exec_data): New structure to hold exec
4787 info that must be preserved when running objcopy/strip.
4788 (struct somdata): Add new "exec_data" field and accessor
4789 macro. Add some comments on how the various fields are used.
4790 (som_section_data_struct): Make is_space and is_subspace bitfields.
4791 Delete unused subspace_index. All references now use the
4792 target_index field within the section structure itself.
4794 * som.c (make_unique_section): Delete unused declaration.
4795 (som_bfd_copy_private_bfd_data): New function.
4796 (som_object_setup): Allocate space for and save exec information
4797 that needs to be copied during objcopy/strip.
4798 (som_mkobject): Do not allocate space for a file header here.
4799 It is not used when only reading SOM objects.
4800 (som_prep_headers): Allocate space for and attach a file header
4801 to the output bfd. For executables, use the saved system_id
4802 value rather than trying to guess the right value. Do not abort
4803 wwhen setting file_hdr->entry* for executables.
4804 (som_begin_writing): For executables, set the exec_entry and
4806 (som_copy_private_backend_section_data): Always return a value.
4808 * libhppa.h (PA_PAGESIZE): Define.
4810 * som.c (SOM_ALIGN): Define.
4811 (som_begin_writing): If writing an executable, initialize all
4812 fields in the exec header to zero. Update fields in the exec
4813 header as sizes of loadable subspaces are computed. Carefully
4814 preserve alignments when building executables. Actually write the
4815 exec after all the fields are filled in.
4817 * Better long-filename handling. Reads SOM ABI compliant extended
4818 names, but doesn't quite write compliant extended names yet.
4819 * som.c (som_slurp_extended_name_table): Delete function. The
4820 generic code will handle things correctly.
4821 (som_slurp_armap): Seek to the beginning of the next member.
4822 (normalize): New function.
4823 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4824 name table into account when computing the file offsets in the
4825 SOM dictionary. Make sure to align to an even boundary.
4826 (som_write_armap): Initialize the checksum to zero.
4827 (ar_maxchars): Fix. Opps.
4829 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4831 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4832 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4834 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4836 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4837 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4838 * bfd-in2.h: Regenerated.
4840 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4841 this was also named trad_unix_bfd_copy_private_bfd_data.
4843 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4845 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4846 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4847 returns NULL, it is not an error. It's possible that some of
4848 these checks are not necessary (because the size can never be
4849 zero), but putting in the checks is the conservative thing to do
4850 in light of the fact that some of these malloc calls replaced
4851 unchecked alloca calls, in which a zero argument would work fine.
4853 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4855 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4856 duplicate definition.
4857 (osf_core_bfd_is_local_label): Define.
4859 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4860 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4861 failure indication, it merely means there are no relocs.
4863 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4864 after NAME, since SunOS /bin/cc can't handle it.
4866 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4868 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4869 From sukes@glue.umd.edu (Tasuki Hirata).
4871 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4873 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4874 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4875 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4877 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4879 * som.c (som_prep_for_fixups): Detect section symbols based
4880 on either the lack of private data or the symbol flags. Do not
4881 munge section symbol names anymore -- they no longer confuse GDB.
4882 (som_begin_writing): Leave space for an exec header if writing
4884 (som_slurp_symbol_table): Recognize both forms of section symbol
4885 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4886 section symbols to be the name of the section they represent.
4887 Debugging symbols begin with "L$0\001", not just "L$".
4889 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4891 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4893 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4894 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4895 and bfd_is_local_label.
4897 * targets.c: Add new entries to the bfd_target structure.
4899 * bfd.c (bfd_copy_private_bfd_data): New definition.
4901 * section.c (bfd_copy_private_section_data): New definition.
4903 * syms.c (bfd_is_local_label): New definition.
4905 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4907 * libbfd.c (bfd_generic_is_local_label): New function.
4909 * *-core.c: Provide default definitions for new functions in
4910 the target vector which all point to bfd_false.
4912 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4913 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4914 Default new vectors for copying private backend data to bfd_true.
4915 Default new vector for determining if a symbol is a local label
4916 to bfd_generic_is_local_label.
4918 * som.c (som_bfd_copy_private_section_data): New function.
4919 (som_bfd_is_local_label): New function.
4920 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4922 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4924 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4926 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4928 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4931 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4932 Indent some of them to GNU standards.
4934 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4935 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4936 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4937 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4938 Update copyright years.
4940 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4942 * som.c (som_prep_for_fixups): A relocation involving the section
4943 symbol for the *ABS* section is really a relocation involving
4945 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4946 undefined symbols. Correctly distinguish between debugger symbols
4947 and section symbols.
4949 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4950 for spaces and subspaces.
4952 * som.c (som_bfd_count_ar_symbols): Fix typo.
4954 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4955 HAS_RELOC based on the object's magic number.
4956 (make_unique_section): Delete function. BFD and its users are
4957 prepared to handle multiple sections with the same name.
4958 (setup_sections): Allocate space on the BFD's obstack to hold
4959 section names. Use bfd_make_setion_anyway rather than the
4960 obsolete make_unique_section.
4961 (som_prep_headers): Choose the correct SOM magic number based
4963 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4965 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4967 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4968 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4969 * Makefile.in, configure.in: Corresponding changes.

4977 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4978 is always located at the start of the data section to allow
4979 recovery of the dynamic info from a stripped executable.
4980 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4983 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4985 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4986 cruft (like the #pragma alloca for AIX).
4987 In addition to that problem, the C alloca calls xmalloc, which
4988 means checking for being out of memory can't work right. The
4989 following changes remove all uses of alloca from BFD.
4990 * hosts/solaris2.h: Remove alloca cruft.
4991 * som.c: Replace alloca with a fixed size auto array.
4992 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4993 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4994 sunos.c: Replace alloca with malloc and appropriate error checking and
4996 * linker.c: Replace alloca with obstack_alloc.
4997 * libbfd.h: Rebuilt.
4999 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5001 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5004 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5006 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5007 Elf*_Off typedefs by their expansion, the typedefs have been
5008 removed from include/elf/internal.h.
5009 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5010 SHT_PROGBITS section.
5012 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5014 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5020 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5021 return from bfd_seek indicates an error.
5022 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5023 TRAD_CORE_STACK_OFFSET.
5024 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5025 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5027 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5029 * som.[ch]: Do not include libhppa.h in som.c, instead include
5032 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5033 include it in elf32-hppa.h.
5035 * som.c (log2): Return -1 on error rather than aborting.
5036 (setup_sections): Bubble up an error from log2.
5038 * Changes to make HP C compiler happy in both traditional
5040 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5042 (bfd_som_set_section_attributes): Use unsigned int rather than
5043 unsigned char to avoid GNU-C extensions.
5044 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5045 or failure rather than aborting on failure.
5047 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5049 (bfd_som_attach_aux_hdr): Add prototype.
5050 (hppa_som-gen_reloc_type): Likewise.
5052 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5053 (hppa_look_for_stubs_in_section): Do not return false on failure
5054 until rest of code is ready to handle it. Abort for now.

5079 action in case where caller specified no argument relocation.
5080 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5081 right in the original relocation and the stub's relocation.
5083 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5084 unused symbols argument.
5086 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5088 Set reloc->sym_ptr_ptr appropriately.
5089 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5090 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5091 argument. Use the output symbols when canonicalizing the relocs,
5092 creating them if necessary.
5094 * linker.c (_bfd_generic_link_output_symbols): Do not
5095 rebuild/clobber the output symbols if they already exist.
5097 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5099 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5101 * bfd-in2.h: Rebuilt.
5103 * srec.c (hex_value): Always set to a size of 256 bytes.
5104 (srec_init): Cosmetic changes.
5106 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5109 PARAMize and staticize rest of functions. Delete unused
5110 functions. Delete unused/unnecessary arguments to some functions.
5111 Group static vars together. Abort for bad errors until we have
5112 error code propogation working. Work on spacing and indention.
5113 Add FIXMEs for unresolved problems. Use enums rather than
5114 #defines for lots of things. Merge two functions which build
5115 linker stubs into a single function (so they can easily share a
5116 ton of common code).
5118 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5120 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5121 avoid depending upon right shifts of signed numbers, and to
5122 correct handling of src_mask with lower bits zero.
5124 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

5152 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5153 (elf_hppa_tc_make_sections): Likewise.
5154 (elf_hppa_final_processing): Add extern decl.
5156 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5157 comments. PARAMize some static functions. Delete unused functions.
5158 Delete unused/unnecessary arguments to many functions. Group
5159 static vars together. Collapse common case statements together
5160 in many places. Use default case when possible instead of listing
5161 each case separately. Abort for bad errors until we get error
5162 code propogation working. Work on spacing and indention problems.
5163 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5164 COMPLEX relocation support (it's never used anyway).
5165 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5166 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5167 (elf_hppa_tc_make_sections): Likewise.
5169 * format.c (bfd_check_format_matches): Initialize matching_vector

5180 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
5182 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

5208 * elfcode.h (alloca): Delete declaration.
5210 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5211 number rather than HP9000S800_ID. Note som.c is careful
5212 to make sure CPU_PA_RISC1_0 is always defined.
5214 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5216 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply
5217 flags to explicit compile actions.

6014 use get_value to get the symbol value and check for undefined
6016 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6017 undefined, look it up in the linker hash table.
6019 * aoutx.h (translate_symbol_table): The string index 0 has a

6044 The sparc (and possibly other?) NLM format requires a different
6045 way to write exports, so add a write_export field to the backend
6046 data (and set it to NULL for everything but the sparc).
