5691 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5693 * som.h (som_copyable_section_data_struct): New structure
5694 containing all the private section information which needs
5695 to be copied from input section to output section during
5697 (som_section_data_struct): Remove several fields now in
5698 som_copyable_section_data_struct. Make the space and
5699 subspace dictionaries be pointers (to save space when
5700 only reading objects).
5702 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5703 some references changed. Allocate a copyable data stucture if
5704 none exists. Store info into the copyable data structure.
5705 (bfd_som_set_subsection_attributes): Likewise.
5706 (som_is_space, som_is_subspace, som_is_container): New functions.
5707 Use these instead of directly accessing private data.
5708 (som_prep_headers): Allocate space and subspace headers here.
5709 Fill in some fields in the space/subspace headers from the
5711 (som_bfd_copy_private_section_data): Only copy the stuff
5712 that we really need to make objcopy and strip work. Allocate
5713 the copy_data structure for the output bfd before copying.
5715 * som.h (struct som_exec_data): New structure to hold exec
5716 info that must be preserved when running objcopy/strip.
5717 (struct somdata): Add new "exec_data" field and accessor
5718 macro. Add some comments on how the various fields are used.
5719 (som_section_data_struct): Make is_space and is_subspace bitfields.
5720 Delete unused subspace_index. All references now use the
5721 target_index field within the section structure itself.
5723 * som.c (make_unique_section): Delete unused declaration.
5724 (som_bfd_copy_private_bfd_data): New function.
5725 (som_object_setup): Allocate space for and save exec information
5726 that needs to be copied during objcopy/strip.
5727 (som_mkobject): Do not allocate space for a file header here.
5728 It is not used when only reading SOM objects.
5729 (som_prep_headers): Allocate space for and attach a file header
5730 to the output bfd. For executables, use the saved system_id
5731 value rather than trying to guess the right value. Do not abort
5732 wwhen setting file_hdr->entry* for executables.
5733 (som_begin_writing): For executables, set the exec_entry and
5735 (som_copy_private_backend_section_data): Always return a value.
5737 * libhppa.h (PA_PAGESIZE): Define.
5739 * som.c (SOM_ALIGN): Define.
5740 (som_begin_writing): If writing an executable, initialize all
5741 fields in the exec header to zero. Update fields in the exec
5742 header as sizes of loadable subspaces are computed. Carefully
5743 preserve alignments when building executables. Actually write the
5744 exec after all the fields are filled in.
5746 * Better long-filename handling. Reads SOM ABI compliant extended
5747 names, but doesn't quite write compliant extended names yet.
5748 * som.c (som_slurp_extended_name_table): Delete function. The
5749 generic code will handle things correctly.
5750 (som_slurp_armap): Seek to the beginning of the next member.
5751 (normalize): New function.
5752 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5753 name table into account when computing the file offsets in the
5754 SOM dictionary. Make sure to align to an even boundary.
5755 (som_write_armap): Initialize the checksum to zero.
5756 (ar_maxchars): Fix. Opps.
5758 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5760 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5761 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5763 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5765 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5766 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5767 * bfd-in2.h: Regenerated.
5769 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5770 this was also named trad_unix_bfd_copy_private_bfd_data.
5772 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5774 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5775 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5776 returns NULL, it is not an error. It's possible that some of
5777 these checks are not necessary (because the size can never be
5778 zero), but putting in the checks is the conservative thing to do
5779 in light of the fact that some of these malloc calls replaced
5780 unchecked alloca calls, in which a zero argument would work fine.
5782 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5784 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5785 duplicate definition.
5786 (osf_core_bfd_is_local_label): Define.
5788 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5789 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5790 failure indication, it merely means there are no relocs.
5792 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5793 after NAME, since SunOS /bin/cc can't handle it.
5795 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5797 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5798 From sukes@glue.umd.edu (Tasuki Hirata).
5800 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5802 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5803 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5804 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5806 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5808 * som.c (som_prep_for_fixups): Detect section symbols based
5809 on either the lack of private data or the symbol flags. Do not
5810 munge section symbol names anymore -- they no longer confuse GDB.
5811 (som_begin_writing): Leave space for an exec header if writing
5813 (som_slurp_symbol_table): Recognize both forms of section symbol
5814 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5815 section symbols to be the name of the section they represent.
5816 Debugging symbols begin with "L$0\001", not just "L$".
5818 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5820 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5822 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5823 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5824 and bfd_is_local_label.
5826 * targets.c: Add new entries to the bfd_target structure.
5828 * bfd.c (bfd_copy_private_bfd_data): New definition.
5830 * section.c (bfd_copy_private_section_data): New definition.
5832 * syms.c (bfd_is_local_label): New definition.
5834 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5836 * libbfd.c (bfd_generic_is_local_label): New function.
5838 * *-core.c: Provide default definitions for new functions in
5839 the target vector which all point to bfd_false.
5841 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5842 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5843 Default new vectors for copying private backend data to bfd_true.
5844 Default new vector for determining if a symbol is a local label
5845 to bfd_generic_is_local_label.
5847 * som.c (som_bfd_copy_private_section_data): New function.
5848 (som_bfd_is_local_label): New function.
5849 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5851 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5853 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5855 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5857 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5860 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5861 Indent some of them to GNU standards.
5863 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5864 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5865 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5866 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5867 Update copyright years.
5869 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5871 * som.c (som_prep_for_fixups): A relocation involving the section
5872 symbol for the *ABS* section is really a relocation involving
5874 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5875 undefined symbols. Correctly distinguish between debugger symbols
5876 and section symbols.
5878 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5879 for spaces and subspaces.
5881 * som.c (som_bfd_count_ar_symbols): Fix typo.
5883 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5884 HAS_RELOC based on the object's magic number.
5885 (make_unique_section): Delete function. BFD and its users are
5886 prepared to handle multiple sections with the same name.
5887 (setup_sections): Allocate space on the BFD's obstack to hold
5888 section names. Use bfd_make_setion_anyway rather than the
5889 obsolete make_unique_section.
5890 (som_prep_headers): Choose the correct SOM magic number based
5892 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5906 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5907 is always located at the start of the data section to allow
5908 recovery of the dynamic info from a stripped executable.
5909 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5912 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5914 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5915 cruft (like the #pragma alloca for AIX).
5916 In addition to that problem, the C alloca calls xmalloc, which
5917 means checking for being out of memory can't work right. The
5918 following changes remove all uses of alloca from BFD.
5919 * hosts/solaris2.h: Remove alloca cruft.
5920 * som.c: Replace alloca with a fixed size auto array.
5921 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5922 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5923 sunos.c: Replace alloca with malloc and appropriate error checking and
5925 * linker.c: Replace alloca with obstack_alloc.
5926 * libbfd.h: Rebuilt.
5928 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5930 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5933 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5935 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5936 Elf*_Off typedefs by their expansion, the typedefs have been
5937 removed from include/elf/internal.h.
5938 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5939 SHT_PROGBITS section.
5941 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5943 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5949 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5950 return from bfd_seek indicates an error.
5951 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5952 TRAD_CORE_STACK_OFFSET.
5953 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5954 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5956 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5958 * som.[ch]: Do not include libhppa.h in som.c, instead include
5961 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5962 include it in elf32-hppa.h.
5964 * som.c (log2): Return -1 on error rather than aborting.
5965 (setup_sections): Bubble up an error from log2.
5967 * Changes to make HP C compiler happy in both traditional
5969 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5971 (bfd_som_set_section_attributes): Use unsigned int rather than
5972 unsigned char to avoid GNU-C extensions.
5973 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5974 or failure rather than aborting on failure.
5976 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5978 (bfd_som_attach_aux_hdr): Add prototype.
5979 (hppa_som-gen_reloc_type): Likewise.
5981 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5982 (hppa_look_for_stubs_in_section): Do not return false on failure
5983 until rest of code is ready to handle it. Abort for now.

6009 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6010 right in the original relocation and the stub's relocation.

6013 unused symbols argument.
6015 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

6017 Set reloc->sym_ptr_ptr appropriately.
6018 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6019 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6020 argument. Use the output symbols when canonicalizing the relocs,
6021 creating them if necessary.
6023 * linker.c (_bfd_generic_link_output_symbols): Do not
6024 rebuild/clobber the output symbols if they already exist.
6026 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6028 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

6038 PARAMize and staticize rest of functions. Delete unused
6039 functions. Delete unused/unnecessary arguments to some functions.
6040 Group static vars together. Abort for bad errors until we have
6041 error code propogation working. Work on spacing and indention.
6042 Add FIXMEs for unresolved problems. Use enums rather than
6043 #defines for lots of things. Merge two functions which build
6044 linker stubs into a single function (so they can easily share a
6045 ton of common code).
6047 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
6049 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
6050 avoid depending upon right shifts of signed numbers, and to
6051 correct handling of src_mask with lower bits zero.
6053 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

6081 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
6082 (elf_hppa_tc_make_sections): Likewise.
6083 (elf_hppa_final_processing): Add extern decl.
6085 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
6086 comments. PARAMize some static functions. Delete unused functions.
6087 Delete unused/unnecessary arguments to many functions. Group
6088 static vars together. Collapse common case statements together
6089 in many places. Use default case when possible instead of listing
6090 each case separately. Abort for bad errors until we get error
6091 code propogation working. Work on spacing and indention problems.
6092 Add FIXMEs for some unresolved problems. Delete hopelessly broken
6093 COMPLEX relocation support (it's never used anyway).
6094 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
6095 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
6096 (elf_hppa_tc_make_sections): Likewise.

6109 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
6111 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

6137 * elfcode.h (alloca): Delete declaration.
6139 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
6140 number rather than HP9000S800_ID. Note som.c is careful
6141 to make sure CPU_PA_RISC1_0 is always defined.
6143 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
6145 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply
6146 flags to explicit compile actions.

6943 use get_value to get the symbol value and check for undefined
6945 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6946 undefined, look it up in the linker hash table.
6948 * aoutx.h (translate_symbol_table): The string index 0 has a

6973 The sparc (and possibly other?) NLM format requires a different
6974 way to write exports, so add a write_export field to the backend
6975 data (and set it to NULL for everything but the sparc).

7025 read_dynamic_relocs fields.
7026 * aout-target.h (MY(backend_data)): Initialize
