2106 an empty .plt section.
2107 (elf32_sparc_relocate_section): For a GOT reloc against a global
2108 symbol when no dynamic object was seen, initialize the contents of
2109 the .got section. For a GOT reloc against a local symbol, only

5684 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5686 Support for link_order types which generate relocs in order to
5687 support -Ur in the linker.
5688 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5689 from call to _bfd_generic_link_add_one_symbol.
5690 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5691 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5692 instead of bitsize to add_to_set call back.
5693 (_bfd_generic_final_link): Account for link_order relocs when
5694 allocating space for relocations. Handle them in link_order loop.
5695 (_bfd_generic_reloc_link_order): New function.
5696 (_bfd_default_link_order): If a reloc_link_order is seen here,
5698 (_bfd_count_link_order_relocs): New function.
5699 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5700 argument from declaration.
5701 (_bfd_generic_reloc_link_order): Declare.
5702 (_bfd_count_link_order_relocs): Declare.
5703 * libbfd.h: Rebuilt.
5704 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5705 call to _bfd_generic_link_add_one_symbol.
5706 (NAME(aout,final_link)): Account for link_order relocs when
5707 allocating space for relocations. Handle them after handling all
5709 (aout_link_reloc_link_order): New function.
5710 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
5711 call to _bfd_generic_link_add_one_symbol.
5712 (ecoff_bfd_final_link): Account for link_order relocs when
5713 allocating space for relocations. Handle them in link_order loop.
5714 (ecoff_link_write_external): Set the storage class of a defined
5715 linker created symbol based on the section it is in. Correct
5716 bfd_link_hash_weak case to use .sc rather than .st.
5717 (ecoff_reloc_link_order): New function.
5718 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5720 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5722 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5725 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5726 bfd_zmalloc. Free a pointer, not a union.
5727 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5729 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5731 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5733 * som.c (bfd_section_from_som_symbol): Only to do the value
5734 comparison for function symbols within executables.
5736 * som.c (bfd_section_from_som_symbol): Renamed from
5737 som_section_from_subspace_index. Pass in a native SOM symbol.
5738 For executables, iterate through the sections to find out
5739 which contains the symbol's address rather than using the
5740 symbol_info field. (symbol_info has a different meaning for
5741 dynamicly linked executables.)
5743 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5746 * som.c (som_begin_writing): Fix braino (one call to align
5747 space/subspace data was done unconditionally rather than
5748 just for executables.)
5750 * som.c (som_begin_writing): Align text in all executables to
5751 make HPUX kernel happy. Fixes strip/objcopy for shared
5754 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5756 * som.c (som_begin_writing): Account for alignment needs of
5757 subspaces too when writing executables. Never request a negative
5758 bss size. Fixes some problems with demand paged executables,
5759 still having problems with pure executables and shared executables.
5761 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5763 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5764 bfd_zalloc for rawptr, because later on we may call free, not
5767 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5768 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5769 * cisco-core.c: New file.
5770 * Makefile.in: Change accordingly.
5771 * configure.in: Recognize cisco_core_vec.
5772 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5773 * targets.c: Add cisco_core_vec.
5774 * bfd-in2.h: Rebuilt.
5776 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5778 * som.h (som_copyable_section_data_struct): New structure
5779 containing all the private section information which needs
5780 to be copied from input section to output section during
5782 (som_section_data_struct): Remove several fields now in
5783 som_copyable_section_data_struct. Make the space and
5784 subspace dictionaries be pointers (to save space when
5785 only reading objects).
5787 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5788 some references changed. Allocate a copyable data stucture if
5789 none exists. Store info into the copyable data structure.
5790 (bfd_som_set_subsection_attributes): Likewise.
5791 (som_is_space, som_is_subspace, som_is_container): New functions.
5792 Use these instead of directly accessing private data.
5793 (som_prep_headers): Allocate space and subspace headers here.
5794 Fill in some fields in the space/subspace headers from the
5796 (som_bfd_copy_private_section_data): Only copy the stuff
5797 that we really need to make objcopy and strip work. Allocate
5798 the copy_data structure for the output bfd before copying.
5800 * som.h (struct som_exec_data): New structure to hold exec
5801 info that must be preserved when running objcopy/strip.
5802 (struct somdata): Add new "exec_data" field and accessor
5803 macro. Add some comments on how the various fields are used.
5804 (som_section_data_struct): Make is_space and is_subspace bitfields.
5805 Delete unused subspace_index. All references now use the
5806 target_index field within the section structure itself.
5808 * som.c (make_unique_section): Delete unused declaration.
5809 (som_bfd_copy_private_bfd_data): New function.
5810 (som_object_setup): Allocate space for and save exec information
5811 that needs to be copied during objcopy/strip.
5812 (som_mkobject): Do not allocate space for a file header here.
5813 It is not used when only reading SOM objects.
5814 (som_prep_headers): Allocate space for and attach a file header
5815 to the output bfd. For executables, use the saved system_id
5816 value rather than trying to guess the right value. Do not abort
5817 wwhen setting file_hdr->entry* for executables.
5818 (som_begin_writing): For executables, set the exec_entry and
5820 (som_copy_private_backend_section_data): Always return a value.
5822 * libhppa.h (PA_PAGESIZE): Define.
5824 * som.c (SOM_ALIGN): Define.
5825 (som_begin_writing): If writing an executable, initialize all
5826 fields in the exec header to zero. Update fields in the exec
5827 header as sizes of loadable subspaces are computed. Carefully
5828 preserve alignments when building executables. Actually write the
5829 exec after all the fields are filled in.
5831 * Better long-filename handling. Reads SOM ABI compliant extended
5832 names, but doesn't quite write compliant extended names yet.
5833 * som.c (som_slurp_extended_name_table): Delete function. The
5834 generic code will handle things correctly.
5835 (som_slurp_armap): Seek to the beginning of the next member.
5836 (normalize): New function.
5837 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5838 name table into account when computing the file offsets in the
5839 SOM dictionary. Make sure to align to an even boundary.
5840 (som_write_armap): Initialize the checksum to zero.
5841 (ar_maxchars): Fix. Opps.
5843 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5845 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5846 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5848 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5850 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5851 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5852 * bfd-in2.h: Regenerated.
5854 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5855 this was also named trad_unix_bfd_copy_private_bfd_data.
5857 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5859 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5860 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5861 returns NULL, it is not an error. It's possible that some of
5862 these checks are not necessary (because the size can never be
5863 zero), but putting in the checks is the conservative thing to do
5864 in light of the fact that some of these malloc calls replaced
5865 unchecked alloca calls, in which a zero argument would work fine.
5867 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5869 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5870 duplicate definition.
5871 (osf_core_bfd_is_local_label): Define.
5873 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5874 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5875 failure indication, it merely means there are no relocs.
5877 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5878 after NAME, since SunOS /bin/cc can't handle it.
5880 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5882 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5883 From sukes@glue.umd.edu (Tasuki Hirata).
5885 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5887 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5888 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5889 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5891 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5893 * som.c (som_prep_for_fixups): Detect section symbols based
5894 on either the lack of private data or the symbol flags. Do not
5895 munge section symbol names anymore -- they no longer confuse GDB.
5896 (som_begin_writing): Leave space for an exec header if writing
5898 (som_slurp_symbol_table): Recognize both forms of section symbol
5899 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5900 section symbols to be the name of the section they represent.
5901 Debugging symbols begin with "L$0\001", not just "L$".
5903 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5905 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5907 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5908 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5909 and bfd_is_local_label.
5911 * targets.c: Add new entries to the bfd_target structure.
5913 * bfd.c (bfd_copy_private_bfd_data): New definition.
5915 * section.c (bfd_copy_private_section_data): New definition.
5917 * syms.c (bfd_is_local_label): New definition.
5919 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5921 * libbfd.c (bfd_generic_is_local_label): New function.
5923 * *-core.c: Provide default definitions for new functions in
5924 the target vector which all point to bfd_false.
5926 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5927 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5928 Default new vectors for copying private backend data to bfd_true.
5929 Default new vector for determining if a symbol is a local label
5930 to bfd_generic_is_local_label.
5932 * som.c (som_bfd_copy_private_section_data): New function.
5933 (som_bfd_is_local_label): New function.
5934 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5936 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5938 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5940 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5942 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5945 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5946 Indent some of them to GNU standards.
5948 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5949 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5950 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5951 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5952 Update copyright years.
5954 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5956 * som.c (som_prep_for_fixups): A relocation involving the section
5957 symbol for the *ABS* section is really a relocation involving
5959 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5960 undefined symbols. Correctly distinguish between debugger symbols
5961 and section symbols.
5963 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5964 for spaces and subspaces.
5966 * som.c (som_bfd_count_ar_symbols): Fix typo.
5968 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5969 HAS_RELOC based on the object's magic number.
5970 (make_unique_section): Delete function. BFD and its users are
5971 prepared to handle multiple sections with the same name.
5972 (setup_sections): Allocate space on the BFD's obstack to hold
5973 section names. Use bfd_make_setion_anyway rather than the
5974 obsolete make_unique_section.
5975 (som_prep_headers): Choose the correct SOM magic number based
5977 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5979 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5981 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5982 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5983 * Makefile.in, configure.in: Corresponding changes.
5985 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5987 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5989 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5991 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5992 is always located at the start of the data section to allow
5993 recovery of the dynamic info from a stripped executable.
5994 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5997 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5999 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6000 cruft (like the #pragma alloca for AIX).
6001 In addition to that problem, the C alloca calls xmalloc, which
6002 means checking for being out of memory can't work right. The
6003 following changes remove all uses of alloca from BFD.
6004 * hosts/solaris2.h: Remove alloca cruft.
6005 * som.c: Replace alloca with a fixed size auto array.
6006 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
6007 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
6008 sunos.c: Replace alloca with malloc and appropriate error checking and
6010 * linker.c: Replace alloca with obstack_alloc.
6011 * libbfd.h: Rebuilt.
6013 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6015 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6018 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6020 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6021 Elf*_Off typedefs by their expansion, the typedefs have been
6022 removed from include/elf/internal.h.
6023 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6024 SHT_PROGBITS section.
6026 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6028 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
6030 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6032 * configure.host: Recognize i[34]86-sequent-*.
6034 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6035 return from bfd_seek indicates an error.
6036 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6037 TRAD_CORE_STACK_OFFSET.
6038 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6039 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6041 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6043 * som.[ch]: Do not include libhppa.h in som.c, instead include
6046 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6047 include it in elf32-hppa.h.
6049 * som.c (log2): Return -1 on error rather than aborting.
6050 (setup_sections): Bubble up an error from log2.
6052 * Changes to make HP C compiler happy in both traditional
6054 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6056 (bfd_som_set_section_attributes): Use unsigned int rather than
6057 unsigned char to avoid GNU-C extensions.
6058 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6059 or failure rather than aborting on failure.
6061 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6063 (bfd_som_attach_aux_hdr): Add prototype.
6064 (hppa_som-gen_reloc_type): Likewise.
6066 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6067 (hppa_look_for_stubs_in_section): Do not return false on failure
6068 until rest of code is ready to handle it. Abort for now.
6070 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6072 * bfd-in2.h: Rebuilt.
6074 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
6076 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
6077 * Makefile.in: delete an extra blank.
6078 * configure.in : Add i396os9k_vec.
6080 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
6082 * config.bfd : Add i386-os9k.
6083 * config/i386-os9k.mt : Newly add os9k target makefile.
6085 * i386os9k.c : new file to handle os9k format bfd.
6086 * Makefile.in : Handle new file i386os9k.c
6087 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
6088 * cache.c : Initialize cache_sentinel to 0.
6090 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6092 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
6093 action in case where caller specified no argument relocation.
6094 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6095 right in the original relocation and the stub's relocation.
6097 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
6098 unused symbols argument.
6100 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
6101 than asymbol * for original target symbol. All callers changed.
6102 Set reloc->sym_ptr_ptr appropriately.
6103 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6104 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6105 argument. Use the output symbols when canonicalizing the relocs,
6106 creating them if necessary.
6108 * linker.c (_bfd_generic_link_output_symbols): Do not
6109 rebuild/clobber the output symbols if they already exist.
6111 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6113 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
6114 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
6115 * bfd-in2.h: Rebuilt.
6117 * srec.c (hex_value): Always set to a size of 256 bytes.
6118 (srec_init): Cosmetic changes.
6120 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6122 * elf32-hppa.c: Second half of major cleanup. More comments,
6123 PARAMize and staticize rest of functions. Delete unused
6124 functions. Delete unused/unnecessary arguments to some functions.
6125 Group static vars together. Abort for bad errors until we have
6126 error code propogation working. Work on spacing and indention.
6127 Add FIXMEs for unresolved problems. Use enums rather than
6128 #defines for lots of things. Merge two functions which build
6129 linker stubs into a single function (so they can easily share a
6130 ton of common code).
6132 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
6134 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
6135 avoid depending upon right shifts of signed numbers, and to

7058 The sparc (and possibly other?) NLM format requires a different
7059 way to write exports, so add a write_export field to the backend
7060 data (and set it to NULL for everything but the sparc).

8336 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
8337 MY_bfd_seclet_link): Define.
8338 (MY_bfd_reloc_type_lookup): Rename from
8339 MY_reloc_howto_type_lookup.
8340 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
8341 (MY(vec)): Use JUMP_TABLE rather than listing functions.
8342 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
8343 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
8344 terms of MY, because that causes a recusive invocation of CAT when
8345 expanded within JUMP_TABLE, and ANSI compilers don't expand
8347 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
8348 MY_reloc_howto_type_lookup, and don't define in terms of MY.
8349 (MY_canonicalize_reloc): Don't define in terms of MY.
8350 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
8351 than listing functions.
