2128 an empty .plt section.
2129 (elf32_sparc_relocate_section): For a GOT reloc against a global
2130 symbol when no dynamic object was seen, initialize the contents of
2131 the .got section. For a GOT reloc against a local symbol, only

5695 * libbfd-in.h (_bfd_generic_link_add_symbols_collect): Declare.
5696 * libbfd.h: Rebuilt.
5698 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5700 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
5701 for first character in an extended name.
5702 (_bfd_write_archive_contents): If ar_padchar == '/', then use
5703 "//" as the name of the special archive member holding the
5704 extended name table.
5706 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5708 Support for link_order types which generate relocs in order to
5709 support -Ur in the linker.
5710 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5711 from call to _bfd_generic_link_add_one_symbol.
5712 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5713 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5714 instead of bitsize to add_to_set call back.
5715 (_bfd_generic_final_link): Account for link_order relocs when
5716 allocating space for relocations. Handle them in link_order loop.
5717 (_bfd_generic_reloc_link_order): New function.
5718 (_bfd_default_link_order): If a reloc_link_order is seen here,
5720 (_bfd_count_link_order_relocs): New function.
5721 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5722 argument from declaration.
5723 (_bfd_generic_reloc_link_order): Declare.
5724 (_bfd_count_link_order_relocs): Declare.
5725 * libbfd.h: Rebuilt.
5726 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5727 call to _bfd_generic_link_add_one_symbol.
5728 (NAME(aout,final_link)): Account for link_order relocs when
5729 allocating space for relocations. Handle them after handling all
5731 (aout_link_reloc_link_order): New function.
5732 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
5733 call to _bfd_generic_link_add_one_symbol.
5734 (ecoff_bfd_final_link): Account for link_order relocs when
5735 allocating space for relocations. Handle them in link_order loop.
5736 (ecoff_link_write_external): Set the storage class of a defined
5737 linker created symbol based on the section it is in. Correct
5738 bfd_link_hash_weak case to use .sc rather than .st.
5739 (ecoff_reloc_link_order): New function.
5740 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5742 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5744 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5747 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5748 bfd_zmalloc. Free a pointer, not a union.
5749 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5751 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5753 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5755 * som.c (bfd_section_from_som_symbol): Only to do the value
5756 comparison for function symbols within executables.
5758 * som.c (bfd_section_from_som_symbol): Renamed from
5759 som_section_from_subspace_index. Pass in a native SOM symbol.
5760 For executables, iterate through the sections to find out
5761 which contains the symbol's address rather than using the
5762 symbol_info field. (symbol_info has a different meaning for
5763 dynamicly linked executables.)
5765 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5768 * som.c (som_begin_writing): Fix braino (one call to align
5769 space/subspace data was done unconditionally rather than
5770 just for executables.)
5772 * som.c (som_begin_writing): Align text in all executables to
5773 make HPUX kernel happy. Fixes strip/objcopy for shared
5776 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5778 * som.c (som_begin_writing): Account for alignment needs of
5779 subspaces too when writing executables. Never request a negative
5780 bss size. Fixes some problems with demand paged executables,
5781 still having problems with pure executables and shared executables.
5783 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5785 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5786 bfd_zalloc for rawptr, because later on we may call free, not
5789 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5790 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5791 * cisco-core.c: New file.
5792 * Makefile.in: Change accordingly.
5793 * configure.in: Recognize cisco_core_vec.
5794 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5795 * targets.c: Add cisco_core_vec.
5796 * bfd-in2.h: Rebuilt.
5798 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5800 * som.h (som_copyable_section_data_struct): New structure
5801 containing all the private section information which needs
5802 to be copied from input section to output section during
5804 (som_section_data_struct): Remove several fields now in
5805 som_copyable_section_data_struct. Make the space and
5806 subspace dictionaries be pointers (to save space when
5807 only reading objects).
5809 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5810 some references changed. Allocate a copyable data stucture if
5811 none exists. Store info into the copyable data structure.
5812 (bfd_som_set_subsection_attributes): Likewise.
5813 (som_is_space, som_is_subspace, som_is_container): New functions.
5814 Use these instead of directly accessing private data.
5815 (som_prep_headers): Allocate space and subspace headers here.
5816 Fill in some fields in the space/subspace headers from the
5818 (som_bfd_copy_private_section_data): Only copy the stuff
5819 that we really need to make objcopy and strip work. Allocate
5820 the copy_data structure for the output bfd before copying.
5822 * som.h (struct som_exec_data): New structure to hold exec
5823 info that must be preserved when running objcopy/strip.
5824 (struct somdata): Add new "exec_data" field and accessor
5825 macro. Add some comments on how the various fields are used.
5826 (som_section_data_struct): Make is_space and is_subspace bitfields.
5827 Delete unused subspace_index. All references now use the
5828 target_index field within the section structure itself.
5830 * som.c (make_unique_section): Delete unused declaration.
5831 (som_bfd_copy_private_bfd_data): New function.
5832 (som_object_setup): Allocate space for and save exec information
5833 that needs to be copied during objcopy/strip.
5834 (som_mkobject): Do not allocate space for a file header here.
5835 It is not used when only reading SOM objects.
5836 (som_prep_headers): Allocate space for and attach a file header
5837 to the output bfd. For executables, use the saved system_id
5838 value rather than trying to guess the right value. Do not abort
5839 wwhen setting file_hdr->entry* for executables.
5840 (som_begin_writing): For executables, set the exec_entry and
5842 (som_copy_private_backend_section_data): Always return a value.
5844 * libhppa.h (PA_PAGESIZE): Define.
5846 * som.c (SOM_ALIGN): Define.
5847 (som_begin_writing): If writing an executable, initialize all
5848 fields in the exec header to zero. Update fields in the exec
5849 header as sizes of loadable subspaces are computed. Carefully
5850 preserve alignments when building executables. Actually write the
5851 exec after all the fields are filled in.
5853 * Better long-filename handling. Reads SOM ABI compliant extended
5854 names, but doesn't quite write compliant extended names yet.
5855 * som.c (som_slurp_extended_name_table): Delete function. The
5856 generic code will handle things correctly.
5857 (som_slurp_armap): Seek to the beginning of the next member.
5858 (normalize): New function.
5859 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5860 name table into account when computing the file offsets in the
5861 SOM dictionary. Make sure to align to an even boundary.
5862 (som_write_armap): Initialize the checksum to zero.
5863 (ar_maxchars): Fix. Opps.
5865 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5867 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5868 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5870 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5872 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5873 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5874 * bfd-in2.h: Regenerated.
5876 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5877 this was also named trad_unix_bfd_copy_private_bfd_data.
5879 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5881 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5882 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5883 returns NULL, it is not an error. It's possible that some of
5884 these checks are not necessary (because the size can never be
5885 zero), but putting in the checks is the conservative thing to do
5886 in light of the fact that some of these malloc calls replaced
5887 unchecked alloca calls, in which a zero argument would work fine.
5889 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5891 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5892 duplicate definition.
5893 (osf_core_bfd_is_local_label): Define.
5895 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5896 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5897 failure indication, it merely means there are no relocs.
5899 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5900 after NAME, since SunOS /bin/cc can't handle it.
5902 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5904 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5905 From sukes@glue.umd.edu (Tasuki Hirata).
5907 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5909 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5910 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5911 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5913 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5915 * som.c (som_prep_for_fixups): Detect section symbols based
5916 on either the lack of private data or the symbol flags. Do not
5917 munge section symbol names anymore -- they no longer confuse GDB.
5918 (som_begin_writing): Leave space for an exec header if writing
5920 (som_slurp_symbol_table): Recognize both forms of section symbol
5921 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5922 section symbols to be the name of the section they represent.
5923 Debugging symbols begin with "L$0\001", not just "L$".
5925 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5927 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5929 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5930 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5931 and bfd_is_local_label.
5933 * targets.c: Add new entries to the bfd_target structure.
5935 * bfd.c (bfd_copy_private_bfd_data): New definition.
5937 * section.c (bfd_copy_private_section_data): New definition.
5939 * syms.c (bfd_is_local_label): New definition.
5941 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5943 * libbfd.c (bfd_generic_is_local_label): New function.
5945 * *-core.c: Provide default definitions for new functions in
5946 the target vector which all point to bfd_false.
5948 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5949 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5950 Default new vectors for copying private backend data to bfd_true.
5951 Default new vector for determining if a symbol is a local label
5952 to bfd_generic_is_local_label.
5954 * som.c (som_bfd_copy_private_section_data): New function.
5955 (som_bfd_is_local_label): New function.
5956 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5958 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5960 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5962 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5964 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5967 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5968 Indent some of them to GNU standards.
5970 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5971 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5972 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5973 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5974 Update copyright years.
5976 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5978 * som.c (som_prep_for_fixups): A relocation involving the section
5979 symbol for the *ABS* section is really a relocation involving
5981 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5982 undefined symbols. Correctly distinguish between debugger symbols
5983 and section symbols.
5985 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5986 for spaces and subspaces.
5988 * som.c (som_bfd_count_ar_symbols): Fix typo.
5990 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5991 HAS_RELOC based on the object's magic number.
5992 (make_unique_section): Delete function. BFD and its users are
5993 prepared to handle multiple sections with the same name.
5994 (setup_sections): Allocate space on the BFD's obstack to hold
5995 section names. Use bfd_make_setion_anyway rather than the
5996 obsolete make_unique_section.
5997 (som_prep_headers): Choose the correct SOM magic number based
5999 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6001 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6003 * elf32-ppc.c: Renamed from elf32-powerpc.c.

6013 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6014 is always located at the start of the data section to allow
6015 recovery of the dynamic info from a stripped executable.
6016 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6019 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6021 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6022 cruft (like the #pragma alloca for AIX).
6023 In addition to that problem, the C alloca calls xmalloc, which
6024 means checking for being out of memory can't work right. The
6025 following changes remove all uses of alloca from BFD.
6026 * hosts/solaris2.h: Remove alloca cruft.
6027 * som.c: Replace alloca with a fixed size auto array.

6033 * libbfd.h: Rebuilt.
6035 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6037 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6040 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6042 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6043 Elf*_Off typedefs by their expansion, the typedefs have been
6044 removed from include/elf/internal.h.
6045 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6046 SHT_PROGBITS section.
6048 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6050 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

6054 * configure.host: Recognize i[34]86-sequent-*.
6056 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6057 return from bfd_seek indicates an error.
6058 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6059 TRAD_CORE_STACK_OFFSET.
6060 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6061 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6063 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6065 * som.[ch]: Do not include libhppa.h in som.c, instead include
6068 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6069 include it in elf32-hppa.h.
6071 * som.c (log2): Return -1 on error rather than aborting.
6072 (setup_sections): Bubble up an error from log2.
6074 * Changes to make HP C compiler happy in both traditional
6076 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6078 (bfd_som_set_section_attributes): Use unsigned int rather than
6079 unsigned char to avoid GNU-C extensions.
6080 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6081 or failure rather than aborting on failure.
6083 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6085 (bfd_som_attach_aux_hdr): Add prototype.
6086 (hppa_som-gen_reloc_type): Likewise.
6088 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6089 (hppa_look_for_stubs_in_section): Do not return false on failure
6090 until rest of code is ready to handle it. Abort for now.

6115 action in case where caller specified no argument relocation.
6116 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6117 right in the original relocation and the stub's relocation.
6119 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
6120 unused symbols argument.
6122 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
6123 than asymbol * for original target symbol. All callers changed.
6124 Set reloc->sym_ptr_ptr appropriately.
6125 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6126 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6127 argument. Use the output symbols when canonicalizing the relocs,
6128 creating them if necessary.
6130 * linker.c (_bfd_generic_link_output_symbols): Do not
6131 rebuild/clobber the output symbols if they already exist.
6133 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6135 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
6136 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
6137 * bfd-in2.h: Rebuilt.

6150 #defines for lots of things. Merge two functions which build
6151 linker stubs into a single function (so they can easily share a
6152 ton of common code).

6375 (b_out_relax_section): If a section contains no relocations, don't
6376 bother processing them.
6377 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6381 that reloc->addend falls between the current source offset and the
6382 raw size of the input section.

8341 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
8343 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
8344 Handle symbol number of zero.
8346 * reloc.c (enum bfd_reloc_code_real): Added
8347 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
8348 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
8349 * bfd-in2.h: Rebuilt.
8350 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
8351 BFD_RELOC_MIPS_LITERAL.
8352 * elf32-mips.c (mips_reloc_map): Handle new relocs.
8353 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
8356 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
8357 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
8358 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
8359 MY_bfd_seclet_link): Define.
8360 (MY_bfd_reloc_type_lookup): Rename from
8361 MY_reloc_howto_type_lookup.
8362 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
8363 (MY(vec)): Use JUMP_TABLE rather than listing functions.
8364 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
8365 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
8366 terms of MY, because that causes a recusive invocation of CAT when
8367 expanded within JUMP_TABLE, and ANSI compilers don't expand
8369 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
8370 MY_reloc_howto_type_lookup, and don't define in terms of MY.
8371 (MY_canonicalize_reloc): Don't define in terms of MY.
8372 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
8373 than listing functions.
8375 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
8377 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
