4764 space/subspace data was done unconditionally rather than
4765 just for executables.)
4767 * som.c (som_begin_writing): Align text in all executables to
4768 make HPUX kernel happy. Fixes strip/objcopy for shared
4771 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4773 * som.c (som_begin_writing): Account for alignment needs of
4774 subspaces too when writing executables. Never request a negative
4775 bss size. Fixes some problems with demand paged executables,
4776 still having problems with pure executables and shared executables.
4778 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4780 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4781 bfd_zalloc for rawptr, because later on we may call free, not
4784 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4785 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4786 * cisco-core.c: New file.
4787 * Makefile.in: Change accordingly.
4788 * configure.in: Recognize cisco_core_vec.
4789 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4790 * targets.c: Add cisco_core_vec.
4791 * bfd-in2.h: Rebuilt.
4793 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4795 * som.h (som_copyable_section_data_struct): New structure
4796 containing all the private section information which needs
4797 to be copied from input section to output section during
4799 (som_section_data_struct): Remove several fields now in
4800 som_copyable_section_data_struct. Make the space and
4801 subspace dictionaries be pointers (to save space when
4802 only reading objects).
4804 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4805 some references changed. Allocate a copyable data stucture if
4806 none exists. Store info into the copyable data structure.
4807 (bfd_som_set_subsection_attributes): Likewise.
4808 (som_is_space, som_is_subspace, som_is_container): New functions.
4809 Use these instead of directly accessing private data.
4810 (som_prep_headers): Allocate space and subspace headers here.
4811 Fill in some fields in the space/subspace headers from the
4813 (som_bfd_copy_private_section_data): Only copy the stuff
4814 that we really need to make objcopy and strip work. Allocate
4815 the copy_data structure for the output bfd before copying.
4817 * som.h (struct som_exec_data): New structure to hold exec
4818 info that must be preserved when running objcopy/strip.
4819 (struct somdata): Add new "exec_data" field and accessor
4820 macro. Add some comments on how the various fields are used.
4821 (som_section_data_struct): Make is_space and is_subspace bitfields.
4822 Delete unused subspace_index. All references now use the
4823 target_index field within the section structure itself.
4825 * som.c (make_unique_section): Delete unused declaration.
4826 (som_bfd_copy_private_bfd_data): New function.
4827 (som_object_setup): Allocate space for and save exec information
4828 that needs to be copied during objcopy/strip.
4829 (som_mkobject): Do not allocate space for a file header here.
4830 It is not used when only reading SOM objects.
4831 (som_prep_headers): Allocate space for and attach a file header
4832 to the output bfd. For executables, use the saved system_id
4833 value rather than trying to guess the right value. Do not abort
4834 wwhen setting file_hdr->entry* for executables.
4835 (som_begin_writing): For executables, set the exec_entry and
4837 (som_copy_private_backend_section_data): Always return a value.
4839 * libhppa.h (PA_PAGESIZE): Define.
4841 * som.c (SOM_ALIGN): Define.
4842 (som_begin_writing): If writing an executable, initialize all
4843 fields in the exec header to zero. Update fields in the exec
4844 header as sizes of loadable subspaces are computed. Carefully
4845 preserve alignments when building executables. Actually write the
4846 exec after all the fields are filled in.
4848 * Better long-filename handling. Reads SOM ABI compliant extended
4849 names, but doesn't quite write compliant extended names yet.
4850 * som.c (som_slurp_extended_name_table): Delete function. The
4851 generic code will handle things correctly.
4852 (som_slurp_armap): Seek to the beginning of the next member.
4853 (normalize): New function.
4854 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4855 name table into account when computing the file offsets in the
4856 SOM dictionary. Make sure to align to an even boundary.
4857 (som_write_armap): Initialize the checksum to zero.
4858 (ar_maxchars): Fix. Opps.
4860 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4862 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4863 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4865 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4867 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4868 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4869 * bfd-in2.h: Regenerated.
4871 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4872 this was also named trad_unix_bfd_copy_private_bfd_data.
4874 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4876 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4877 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4878 returns NULL, it is not an error. It's possible that some of
4879 these checks are not necessary (because the size can never be
4880 zero), but putting in the checks is the conservative thing to do
4881 in light of the fact that some of these malloc calls replaced
4882 unchecked alloca calls, in which a zero argument would work fine.
4884 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4886 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4887 duplicate definition.
4888 (osf_core_bfd_is_local_label): Define.
4890 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4891 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4892 failure indication, it merely means there are no relocs.
4894 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4895 after NAME, since SunOS /bin/cc can't handle it.
4897 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4899 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4900 From sukes@glue.umd.edu (Tasuki Hirata).
4902 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4904 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4905 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4906 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4908 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4910 * som.c (som_prep_for_fixups): Detect section symbols based
4911 on either the lack of private data or the symbol flags. Do not
4912 munge section symbol names anymore -- they no longer confuse GDB.
4913 (som_begin_writing): Leave space for an exec header if writing
4915 (som_slurp_symbol_table): Recognize both forms of section symbol
4916 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4917 section symbols to be the name of the section they represent.
4918 Debugging symbols begin with "L$0\001", not just "L$".
4920 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4922 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4924 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4925 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4926 and bfd_is_local_label.
4928 * targets.c: Add new entries to the bfd_target structure.
4930 * bfd.c (bfd_copy_private_bfd_data): New definition.
4932 * section.c (bfd_copy_private_section_data): New definition.
4934 * syms.c (bfd_is_local_label): New definition.
4936 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4938 * libbfd.c (bfd_generic_is_local_label): New function.
4940 * *-core.c: Provide default definitions for new functions in
4941 the target vector which all point to bfd_false.
4943 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4944 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4945 Default new vectors for copying private backend data to bfd_true.
4946 Default new vector for determining if a symbol is a local label
4947 to bfd_generic_is_local_label.
4949 * som.c (som_bfd_copy_private_section_data): New function.
4950 (som_bfd_is_local_label): New function.
4951 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4953 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4955 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4957 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4959 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4962 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4963 Indent some of them to GNU standards.
4965 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4966 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4967 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4968 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4969 Update copyright years.
4971 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4973 * som.c (som_prep_for_fixups): A relocation involving the section
4974 symbol for the *ABS* section is really a relocation involving
4976 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4977 undefined symbols. Correctly distinguish between debugger symbols
4978 and section symbols.
4980 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4981 for spaces and subspaces.
4983 * som.c (som_bfd_count_ar_symbols): Fix typo.
4985 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4986 HAS_RELOC based on the object's magic number.
4987 (make_unique_section): Delete function. BFD and its users are
4988 prepared to handle multiple sections with the same name.
4989 (setup_sections): Allocate space on the BFD's obstack to hold
4990 section names. Use bfd_make_setion_anyway rather than the
4991 obsolete make_unique_section.
4992 (som_prep_headers): Choose the correct SOM magic number based
4994 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4996 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4998 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4999 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5000 * Makefile.in, configure.in: Corresponding changes.

5008 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5009 is always located at the start of the data section to allow
5010 recovery of the dynamic info from a stripped executable.
5011 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5014 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5016 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5017 cruft (like the #pragma alloca for AIX).
5018 In addition to that problem, the C alloca calls xmalloc, which
5019 means checking for being out of memory can't work right. The
5020 following changes remove all uses of alloca from BFD.
5021 * hosts/solaris2.h: Remove alloca cruft.
5022 * som.c: Replace alloca with a fixed size auto array.
5023 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5024 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5025 sunos.c: Replace alloca with malloc and appropriate error checking and
5027 * linker.c: Replace alloca with obstack_alloc.
5028 * libbfd.h: Rebuilt.
5030 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5032 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5035 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5037 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5038 Elf*_Off typedefs by their expansion, the typedefs have been
5039 removed from include/elf/internal.h.
5040 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5041 SHT_PROGBITS section.
5043 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5045 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5051 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5052 return from bfd_seek indicates an error.
5053 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5054 TRAD_CORE_STACK_OFFSET.
5055 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5056 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5058 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5060 * som.[ch]: Do not include libhppa.h in som.c, instead include
5063 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5064 include it in elf32-hppa.h.
5066 * som.c (log2): Return -1 on error rather than aborting.
5067 (setup_sections): Bubble up an error from log2.
5069 * Changes to make HP C compiler happy in both traditional
5071 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5073 (bfd_som_set_section_attributes): Use unsigned int rather than
5074 unsigned char to avoid GNU-C extensions.
5075 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5076 or failure rather than aborting on failure.
5078 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5080 (bfd_som_attach_aux_hdr): Add prototype.
5081 (hppa_som-gen_reloc_type): Likewise.
5083 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5084 (hppa_look_for_stubs_in_section): Do not return false on failure
5085 until rest of code is ready to handle it. Abort for now.

5110 action in case where caller specified no argument relocation.
5111 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5112 right in the original relocation and the stub's relocation.
5114 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5115 unused symbols argument.
5117 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5118 than asymbol * for original target symbol. All callers changed.
5119 Set reloc->sym_ptr_ptr appropriately.
5120 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5121 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5122 argument. Use the output symbols when canonicalizing the relocs,
5123 creating them if necessary.
5125 * linker.c (_bfd_generic_link_output_symbols): Do not
5126 rebuild/clobber the output symbols if they already exist.
5128 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5130 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5131 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5132 * bfd-in2.h: Rebuilt.
5134 * srec.c (hex_value): Always set to a size of 256 bytes.
5135 (srec_init): Cosmetic changes.
5137 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5139 * elf32-hppa.c: Second half of major cleanup. More comments,
5140 PARAMize and staticize rest of functions. Delete unused
5141 functions. Delete unused/unnecessary arguments to some functions.
5142 Group static vars together. Abort for bad errors until we have
5143 error code propogation working. Work on spacing and indention.
5144 Add FIXMEs for unresolved problems. Use enums rather than
5145 #defines for lots of things. Merge two functions which build
5146 linker stubs into a single function (so they can easily share a
5147 ton of common code).
5149 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5151 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5152 avoid depending upon right shifts of signed numbers, and to
5153 correct handling of src_mask with lower bits zero.
5155 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
5156 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

5181 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
5183 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5184 (elf_hppa_tc_make_sections): Likewise.
5185 (elf_hppa_final_processing): Add extern decl.
5187 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5188 comments. PARAMize some static functions. Delete unused functions.
5189 Delete unused/unnecessary arguments to many functions. Group
5190 static vars together. Collapse common case statements together
5191 in many places. Use default case when possible instead of listing
5192 each case separately. Abort for bad errors until we get error
5193 code propogation working. Work on spacing and indention problems.
5194 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5195 COMPLEX relocation support (it's never used anyway).
5196 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5197 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5198 (elf_hppa_tc_make_sections): Likewise.
5200 * format.c (bfd_check_format_matches): Initialize matching_vector
5201 to keep gcc -Wall quiet.
5203 * elfcode.h (elf_slurp_reloca_table): Fix typo.

5206 not "sizeof (som_symbol_type *)".
5208 * elfcode.h (elf_get_symtab_upper_bound): Use "sizeof (asymbol *)"
5209 not "sizeof (asymbol"). Opps.
5211 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
5213 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.
5214 (bfd_set_gp_size): Can't set gp value on an archive.
5216 Fri Feb 25 12:57:00 1994 Steve Chamberlain (sac@jonny.cygnus.com)

6041 the symbol value and check for undefined symbols.
6042 (get_value): If the symbol is undefined, look it up in the linker
6044 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6045 use get_value to get the symbol value and check for undefined
6047 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6048 undefined, look it up in the linker hash table.
6050 * aoutx.h (translate_symbol_table): The string index 0 has a

6075 The sparc (and possibly other?) NLM format requires a different
6076 way to write exports, so add a write_export field to the backend
6077 data (and set it to NULL for everything but the sparc).
