4766 some references changed. Allocate a copyable data stucture if
4767 none exists. Store info into the copyable data structure.
4768 (bfd_som_set_subsection_attributes): Likewise.
4769 (som_is_space, som_is_subspace, som_is_container): New functions.
4770 Use these instead of directly accessing private data.
4771 (som_prep_headers): Allocate space and subspace headers here.
4772 Fill in some fields in the space/subspace headers from the
4774 (som_bfd_copy_private_section_data): Only copy the stuff
4775 that we really need to make objcopy and strip work. Allocate
4776 the copy_data structure for the output bfd before copying.
4778 * som.h (struct som_exec_data): New structure to hold exec
4779 info that must be preserved when running objcopy/strip.
4780 (struct somdata): Add new "exec_data" field and accessor
4781 macro. Add some comments on how the various fields are used.
4782 (som_section_data_struct): Make is_space and is_subspace bitfields.
4783 Delete unused subspace_index. All references now use the
4784 target_index field within the section structure itself.
4786 * som.c (make_unique_section): Delete unused declaration.
4787 (som_bfd_copy_private_bfd_data): New function.
4788 (som_object_setup): Allocate space for and save exec information
4789 that needs to be copied during objcopy/strip.
4790 (som_mkobject): Do not allocate space for a file header here.
4791 It is not used when only reading SOM objects.
4792 (som_prep_headers): Allocate space for and attach a file header
4793 to the output bfd. For executables, use the saved system_id
4794 value rather than trying to guess the right value. Do not abort
4795 wwhen setting file_hdr->entry* for executables.
4796 (som_begin_writing): For executables, set the exec_entry and
4798 (som_copy_private_backend_section_data): Always return a value.
4800 * libhppa.h (PA_PAGESIZE): Define.
4802 * som.c (SOM_ALIGN): Define.
4803 (som_begin_writing): If writing an executable, initialize all
4804 fields in the exec header to zero. Update fields in the exec
4805 header as sizes of loadable subspaces are computed. Carefully
4806 preserve alignments when building executables. Actually write the
4807 exec after all the fields are filled in.
4809 * Better long-filename handling. Reads SOM ABI compliant extended
4810 names, but doesn't quite write compliant extended names yet.
4811 * som.c (som_slurp_extended_name_table): Delete function. The
4812 generic code will handle things correctly.
4813 (som_slurp_armap): Seek to the beginning of the next member.
4814 (normalize): New function.
4815 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4816 name table into account when computing the file offsets in the
4817 SOM dictionary. Make sure to align to an even boundary.
4818 (som_write_armap): Initialize the checksum to zero.
4819 (ar_maxchars): Fix. Opps.
4821 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4823 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4824 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4826 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4828 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4829 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4830 * bfd-in2.h: Regenerated.
4832 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4833 this was also named trad_unix_bfd_copy_private_bfd_data.
4835 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4837 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4838 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4839 returns NULL, it is not an error. It's possible that some of
4840 these checks are not necessary (because the size can never be
4841 zero), but putting in the checks is the conservative thing to do
4842 in light of the fact that some of these malloc calls replaced
4843 unchecked alloca calls, in which a zero argument would work fine.
4845 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4847 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4848 duplicate definition.

4851 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4852 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4853 failure indication, it merely means there are no relocs.
4855 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4856 after NAME, since SunOS /bin/cc can't handle it.
4858 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4860 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4861 From sukes@glue.umd.edu (Tasuki Hirata).
4863 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4865 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4866 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4867 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4869 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4871 * som.c (som_prep_for_fixups): Detect section symbols based
4872 on either the lack of private data or the symbol flags. Do not
4873 munge section symbol names anymore -- they no longer confuse GDB.
4874 (som_begin_writing): Leave space for an exec header if writing
4876 (som_slurp_symbol_table): Recognize both forms of section symbol
4877 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4878 section symbols to be the name of the section they represent.
4879 Debugging symbols begin with "L$0\001", not just "L$".
4881 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4883 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4885 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4886 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4887 and bfd_is_local_label.
4889 * targets.c: Add new entries to the bfd_target structure.
4891 * bfd.c (bfd_copy_private_bfd_data): New definition.

4902 the target vector which all point to bfd_false.
4904 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4905 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4906 Default new vectors for copying private backend data to bfd_true.
4907 Default new vector for determining if a symbol is a local label
4908 to bfd_generic_is_local_label.
4910 * som.c (som_bfd_copy_private_section_data): New function.
4911 (som_bfd_is_local_label): New function.
4912 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4914 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4916 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4918 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4920 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4923 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4924 Indent some of them to GNU standards.
4926 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4927 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4928 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4929 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4930 Update copyright years.
4932 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4934 * som.c (som_prep_for_fixups): A relocation involving the section
4935 symbol for the *ABS* section is really a relocation involving
4937 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4938 undefined symbols. Correctly distinguish between debugger symbols
4939 and section symbols.
4941 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4942 for spaces and subspaces.
4944 * som.c (som_bfd_count_ar_symbols): Fix typo.
4946 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4947 HAS_RELOC based on the object's magic number.
4948 (make_unique_section): Delete function. BFD and its users are
4949 prepared to handle multiple sections with the same name.
4950 (setup_sections): Allocate space on the BFD's obstack to hold
4951 section names. Use bfd_make_setion_anyway rather than the
4952 obsolete make_unique_section.
4953 (som_prep_headers): Choose the correct SOM magic number based
4955 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4969 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4970 is always located at the start of the data section to allow
4971 recovery of the dynamic info from a stripped executable.
4972 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4975 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4977 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4978 cruft (like the #pragma alloca for AIX).
4979 In addition to that problem, the C alloca calls xmalloc, which
4980 means checking for being out of memory can't work right. The
4981 following changes remove all uses of alloca from BFD.
4982 * hosts/solaris2.h: Remove alloca cruft.
4983 * som.c: Replace alloca with a fixed size auto array.
4984 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

4986 sunos.c: Replace alloca with malloc and appropriate error checking and
4988 * linker.c: Replace alloca with obstack_alloc.
4989 * libbfd.h: Rebuilt.
4991 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4993 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4996 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4998 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4999 Elf*_Off typedefs by their expansion, the typedefs have been
5000 removed from include/elf/internal.h.
5001 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5002 SHT_PROGBITS section.
5004 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5006 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5015 TRAD_CORE_STACK_OFFSET.
5016 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5017 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5019 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5021 * som.[ch]: Do not include libhppa.h in som.c, instead include
5024 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5025 include it in elf32-hppa.h.
5027 * som.c (log2): Return -1 on error rather than aborting.
5028 (setup_sections): Bubble up an error from log2.
5030 * Changes to make HP C compiler happy in both traditional
5032 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5034 (bfd_som_set_section_attributes): Use unsigned int rather than
5035 unsigned char to avoid GNU-C extensions.
5036 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5037 or failure rather than aborting on failure.
5039 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5041 (bfd_som_attach_aux_hdr): Add prototype.
5042 (hppa_som-gen_reloc_type): Likewise.

5072 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5073 right in the original relocation and the stub's relocation.

5076 unused symbols argument.
5078 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5080 Set reloc->sym_ptr_ptr appropriately.
5081 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5082 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5083 argument. Use the output symbols when canonicalizing the relocs,
5084 creating them if necessary.
5086 * linker.c (_bfd_generic_link_output_symbols): Do not
5087 rebuild/clobber the output symbols if they already exist.
5089 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5091 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5101 PARAMize and staticize rest of functions. Delete unused
5102 functions. Delete unused/unnecessary arguments to some functions.

5104 error code propogation working. Work on spacing and indention.
5105 Add FIXMEs for unresolved problems. Use enums rather than
5106 #defines for lots of things. Merge two functions which build
5107 linker stubs into a single function (so they can easily share a
5108 ton of common code).
5110 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5112 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5113 avoid depending upon right shifts of signed numbers, and to
5114 correct handling of src_mask with lower bits zero.

5144 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5145 (elf_hppa_tc_make_sections): Likewise.
5146 (elf_hppa_final_processing): Add extern decl.
5148 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5149 comments. PARAMize some static functions. Delete unused functions.
5150 Delete unused/unnecessary arguments to many functions. Group
5151 static vars together. Collapse common case statements together
5152 in many places. Use default case when possible instead of listing
5153 each case separately. Abort for bad errors until we get error
5154 code propogation working. Work on spacing and indention problems.
5155 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5156 COMPLEX relocation support (it's never used anyway).
5157 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5158 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5159 (elf_hppa_tc_make_sections): Likewise.

5172 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
5174 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

5200 * elfcode.h (alloca): Delete declaration.
5202 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5203 number rather than HP9000S800_ID. Note som.c is careful
5204 to make sure CPU_PA_RISC1_0 is always defined.
5206 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5208 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5220 * som.c (som_bfd_count_ar_symbols): Use a pointer and alloca
5221 rather than an array of variable size.

5746 * srec.c (srec_write_record): Put CONST keyword for "src" before
5747 "unsigned", some compilers don't like it after "unsigned".
5748 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5820 _bfd_generic_link_write_global_symbol): Don't require that all

5866 (only testing for m68k and vax at the moment); do verify that the
5867 preprocessor didn't trash the arch name inside the string version.

5898 bfd_som_set_subsection_attributes): Change parameters from char
5899 to int. Following a prototype with an old-style function definition

6002 the symbol value and check for undefined symbols.
6003 (get_value): If the symbol is undefined, look it up in the linker
6005 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6006 use get_value to get the symbol value and check for undefined
6008 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6009 undefined, look it up in the linker hash table.
6011 * aoutx.h (translate_symbol_table): The string index 0 has a

6036 The sparc (and possibly other?) NLM format requires a different
6037 way to write exports, so add a write_export field to the backend
6038 data (and set it to NULL for everything but the sparc).

6088 read_dynamic_relocs fields.
6089 * aout-target.h (MY(backend_data)): Initialize
