2165 an empty .plt section.
2166 (elf32_sparc_relocate_section): For a GOT reloc against a global
2167 symbol when no dynamic object was seen, initialize the contents of
2168 the .got section. For a GOT reloc against a local symbol, only

5696 in asymbol udata field.
5698 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5700 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
5701 reloc, used in embedded PIC code.

5710 add_symbls entry point.
5712 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5713 counting relocs. Set SEC_RELOC flag for any section which has

5718 * linker.c (_bfd_generic_link_add_symbols): Just call
5719 generic_link_add_symbols.
5720 (_bfd_generic_link_add_symbols_collect): New function, like
5721 _bfd_generic_link_add_symbols but also collect constructors and
5722 destructors by name as collect2 does.
5723 (generic_link_add_symbols): New function, like old
5724 _bfd_generic_link_add_symbols but with collect argument.
5725 (generic_link_add_object_symbols): Take collect argument.

5737 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
5738 for first character in an extended name.
5739 (_bfd_write_archive_contents): If ar_padchar == '/', then use
5740 "//" as the name of the special archive member holding the
5741 extended name table.
5743 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5745 Support for link_order types which generate relocs in order to
5746 support -Ur in the linker.
5747 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5748 from call to _bfd_generic_link_add_one_symbol.
5749 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5750 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5751 instead of bitsize to add_to_set call back.
5752 (_bfd_generic_final_link): Account for link_order relocs when
5753 allocating space for relocations. Handle them in link_order loop.
5754 (_bfd_generic_reloc_link_order): New function.
5755 (_bfd_default_link_order): If a reloc_link_order is seen here,
5757 (_bfd_count_link_order_relocs): New function.
5758 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5759 argument from declaration.
5760 (_bfd_generic_reloc_link_order): Declare.
5761 (_bfd_count_link_order_relocs): Declare.

5763 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5764 call to _bfd_generic_link_add_one_symbol.
5765 (NAME(aout,final_link)): Account for link_order relocs when

5770 call to _bfd_generic_link_add_one_symbol.
5771 (ecoff_bfd_final_link): Account for link_order relocs when
5772 allocating space for relocations. Handle them in link_order loop.
5773 (ecoff_link_write_external): Set the storage class of a defined
5774 linker created symbol based on the section it is in. Correct
5775 bfd_link_hash_weak case to use .sc rather than .st.
5776 (ecoff_reloc_link_order): New function.
5777 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5779 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5784 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5785 bfd_zmalloc. Free a pointer, not a union.
5786 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5788 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5790 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5792 * som.c (bfd_section_from_som_symbol): Only to do the value
5793 comparison for function symbols within executables.
5795 * som.c (bfd_section_from_som_symbol): Renamed from
5796 som_section_from_subspace_index. Pass in a native SOM symbol.
5797 For executables, iterate through the sections to find out
5798 which contains the symbol's address rather than using the
5799 symbol_info field. (symbol_info has a different meaning for
5800 dynamicly linked executables.)
5802 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5805 * som.c (som_begin_writing): Fix braino (one call to align
5806 space/subspace data was done unconditionally rather than
5807 just for executables.)
5809 * som.c (som_begin_writing): Align text in all executables to
5810 make HPUX kernel happy. Fixes strip/objcopy for shared
5813 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5815 * som.c (som_begin_writing): Account for alignment needs of
5816 subspaces too when writing executables. Never request a negative
5817 bss size. Fixes some problems with demand paged executables,
5818 still having problems with pure executables and shared executables.
5820 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5822 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5823 bfd_zalloc for rawptr, because later on we may call free, not
5826 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5827 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5828 * cisco-core.c: New file.
5829 * Makefile.in: Change accordingly.
5830 * configure.in: Recognize cisco_core_vec.
5831 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5832 * targets.c: Add cisco_core_vec.
5833 * bfd-in2.h: Rebuilt.
5835 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5837 * som.h (som_copyable_section_data_struct): New structure
5838 containing all the private section information which needs
5839 to be copied from input section to output section during
5841 (som_section_data_struct): Remove several fields now in
5842 som_copyable_section_data_struct. Make the space and
5843 subspace dictionaries be pointers (to save space when
5844 only reading objects).
5846 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5847 some references changed. Allocate a copyable data stucture if
5848 none exists. Store info into the copyable data structure.
5849 (bfd_som_set_subsection_attributes): Likewise.
5850 (som_is_space, som_is_subspace, som_is_container): New functions.
5851 Use these instead of directly accessing private data.
5852 (som_prep_headers): Allocate space and subspace headers here.
5853 Fill in some fields in the space/subspace headers from the
5855 (som_bfd_copy_private_section_data): Only copy the stuff
5856 that we really need to make objcopy and strip work. Allocate
5857 the copy_data structure for the output bfd before copying.
5859 * som.h (struct som_exec_data): New structure to hold exec
5860 info that must be preserved when running objcopy/strip.
5861 (struct somdata): Add new "exec_data" field and accessor
5862 macro. Add some comments on how the various fields are used.
5863 (som_section_data_struct): Make is_space and is_subspace bitfields.
5864 Delete unused subspace_index. All references now use the
5865 target_index field within the section structure itself.
5867 * som.c (make_unique_section): Delete unused declaration.
5868 (som_bfd_copy_private_bfd_data): New function.
5869 (som_object_setup): Allocate space for and save exec information
5870 that needs to be copied during objcopy/strip.
5871 (som_mkobject): Do not allocate space for a file header here.
5872 It is not used when only reading SOM objects.
5873 (som_prep_headers): Allocate space for and attach a file header
5874 to the output bfd. For executables, use the saved system_id
5875 value rather than trying to guess the right value. Do not abort
5876 wwhen setting file_hdr->entry* for executables.
5877 (som_begin_writing): For executables, set the exec_entry and
5879 (som_copy_private_backend_section_data): Always return a value.
5881 * libhppa.h (PA_PAGESIZE): Define.
5883 * som.c (SOM_ALIGN): Define.
5884 (som_begin_writing): If writing an executable, initialize all
5885 fields in the exec header to zero. Update fields in the exec
5886 header as sizes of loadable subspaces are computed. Carefully
5887 preserve alignments when building executables. Actually write the
5888 exec after all the fields are filled in.
5890 * Better long-filename handling. Reads SOM ABI compliant extended
5891 names, but doesn't quite write compliant extended names yet.
5892 * som.c (som_slurp_extended_name_table): Delete function. The
5893 generic code will handle things correctly.
5894 (som_slurp_armap): Seek to the beginning of the next member.
5895 (normalize): New function.
5896 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5897 name table into account when computing the file offsets in the
5898 SOM dictionary. Make sure to align to an even boundary.
5899 (som_write_armap): Initialize the checksum to zero.
5900 (ar_maxchars): Fix. Opps.
5902 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5904 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5905 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5907 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5909 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5910 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5911 * bfd-in2.h: Regenerated.
5913 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5914 this was also named trad_unix_bfd_copy_private_bfd_data.
5916 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5918 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5919 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5920 returns NULL, it is not an error. It's possible that some of
5921 these checks are not necessary (because the size can never be
5922 zero), but putting in the checks is the conservative thing to do
5923 in light of the fact that some of these malloc calls replaced
5924 unchecked alloca calls, in which a zero argument would work fine.
5926 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5928 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5929 duplicate definition.
5930 (osf_core_bfd_is_local_label): Define.
5932 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5933 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5934 failure indication, it merely means there are no relocs.
5936 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5937 after NAME, since SunOS /bin/cc can't handle it.
5939 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5941 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5942 From sukes@glue.umd.edu (Tasuki Hirata).
5944 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5946 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5947 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5948 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5950 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5952 * som.c (som_prep_for_fixups): Detect section symbols based
5953 on either the lack of private data or the symbol flags. Do not
5954 munge section symbol names anymore -- they no longer confuse GDB.
5955 (som_begin_writing): Leave space for an exec header if writing
5957 (som_slurp_symbol_table): Recognize both forms of section symbol
5958 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5959 section symbols to be the name of the section they represent.
5960 Debugging symbols begin with "L$0\001", not just "L$".
5962 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5964 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5966 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5967 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5968 and bfd_is_local_label.
5970 * targets.c: Add new entries to the bfd_target structure.
5972 * bfd.c (bfd_copy_private_bfd_data): New definition.
5974 * section.c (bfd_copy_private_section_data): New definition.
5976 * syms.c (bfd_is_local_label): New definition.
5978 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5980 * libbfd.c (bfd_generic_is_local_label): New function.
5982 * *-core.c: Provide default definitions for new functions in
5983 the target vector which all point to bfd_false.
5985 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5986 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5987 Default new vectors for copying private backend data to bfd_true.
5988 Default new vector for determining if a symbol is a local label
5989 to bfd_generic_is_local_label.
5991 * som.c (som_bfd_copy_private_section_data): New function.
5992 (som_bfd_is_local_label): New function.
5993 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5995 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5997 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5999 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6001 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6004 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6005 Indent some of them to GNU standards.
6007 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6008 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6009 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6010 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6011 Update copyright years.
6013 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6015 * som.c (som_prep_for_fixups): A relocation involving the section
6016 symbol for the *ABS* section is really a relocation involving
6018 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6019 undefined symbols. Correctly distinguish between debugger symbols
6020 and section symbols.
6022 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6023 for spaces and subspaces.
6025 * som.c (som_bfd_count_ar_symbols): Fix typo.
6027 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6028 HAS_RELOC based on the object's magic number.
6029 (make_unique_section): Delete function. BFD and its users are
6030 prepared to handle multiple sections with the same name.
6031 (setup_sections): Allocate space on the BFD's obstack to hold
6032 section names. Use bfd_make_setion_anyway rather than the
6033 obsolete make_unique_section.
6034 (som_prep_headers): Choose the correct SOM magic number based
6036 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6038 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6040 * elf32-ppc.c: Renamed from elf32-powerpc.c.

6050 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6051 is always located at the start of the data section to allow
6052 recovery of the dynamic info from a stripped executable.
6053 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6056 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6058 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6059 cruft (like the #pragma alloca for AIX).
6060 In addition to that problem, the C alloca calls xmalloc, which
6061 means checking for being out of memory can't work right. The
6062 following changes remove all uses of alloca from BFD.
6063 * hosts/solaris2.h: Remove alloca cruft.
6064 * som.c: Replace alloca with a fixed size auto array.

6070 * libbfd.h: Rebuilt.
6072 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6074 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6077 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6079 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6080 Elf*_Off typedefs by their expansion, the typedefs have been
6081 removed from include/elf/internal.h.
6082 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6083 SHT_PROGBITS section.
6085 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6087 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

6091 * configure.host: Recognize i[34]86-sequent-*.
6093 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6094 return from bfd_seek indicates an error.
6095 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6096 TRAD_CORE_STACK_OFFSET.
6097 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6098 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6100 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6102 * som.[ch]: Do not include libhppa.h in som.c, instead include
6105 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6106 include it in elf32-hppa.h.
6108 * som.c (log2): Return -1 on error rather than aborting.
6109 (setup_sections): Bubble up an error from log2.
6111 * Changes to make HP C compiler happy in both traditional
6113 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6115 (bfd_som_set_section_attributes): Use unsigned int rather than
6116 unsigned char to avoid GNU-C extensions.
6117 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6118 or failure rather than aborting on failure.
6120 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6122 (bfd_som_attach_aux_hdr): Add prototype.
6123 (hppa_som-gen_reloc_type): Likewise.
6125 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6126 (hppa_look_for_stubs_in_section): Do not return false on failure
6127 until rest of code is ready to handle it. Abort for now.
6129 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6131 * bfd-in2.h: Rebuilt.
6133 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
6135 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

6237 COMPLEX relocation support (it's never used anyway).
6238 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

6413 bother processing them.
6414 (b_out_get_relocated_section_contents): Set reloc_done. Assert

7117 The sparc (and possibly other?) NLM format requires a different
7118 way to write exports, so add a write_export field to the backend
7119 data (and set it to NULL for everything but the sparc).
