2072 an empty .plt section.
2073 (elf32_sparc_relocate_section): For a GOT reloc against a global
2074 symbol when no dynamic object was seen, initialize the contents of
2075 the .got section. For a GOT reloc against a local symbol, only

5682 bfd_link_hash_weak case to use .sc rather than .st.
5683 (ecoff_reloc_link_order): New function.
5684 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5686 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5688 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5691 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5692 bfd_zmalloc. Free a pointer, not a union.
5693 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5695 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5697 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5699 * som.c (bfd_section_from_som_symbol): Only to do the value
5700 comparison for function symbols within executables.
5702 * som.c (bfd_section_from_som_symbol): Renamed from
5703 som_section_from_subspace_index. Pass in a native SOM symbol.
5704 For executables, iterate through the sections to find out
5705 which contains the symbol's address rather than using the
5706 symbol_info field. (symbol_info has a different meaning for
5707 dynamicly linked executables.)
5709 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5712 * som.c (som_begin_writing): Fix braino (one call to align
5713 space/subspace data was done unconditionally rather than
5714 just for executables.)
5716 * som.c (som_begin_writing): Align text in all executables to
5717 make HPUX kernel happy. Fixes strip/objcopy for shared
5720 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5722 * som.c (som_begin_writing): Account for alignment needs of
5723 subspaces too when writing executables. Never request a negative
5724 bss size. Fixes some problems with demand paged executables,
5725 still having problems with pure executables and shared executables.
5727 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5729 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5730 bfd_zalloc for rawptr, because later on we may call free, not
5733 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5734 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5735 * cisco-core.c: New file.
5736 * Makefile.in: Change accordingly.
5737 * configure.in: Recognize cisco_core_vec.
5738 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5739 * targets.c: Add cisco_core_vec.
5740 * bfd-in2.h: Rebuilt.
5742 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5744 * som.h (som_copyable_section_data_struct): New structure
5745 containing all the private section information which needs
5746 to be copied from input section to output section during
5748 (som_section_data_struct): Remove several fields now in
5749 som_copyable_section_data_struct. Make the space and
5750 subspace dictionaries be pointers (to save space when
5751 only reading objects).
5753 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5754 some references changed. Allocate a copyable data stucture if
5755 none exists. Store info into the copyable data structure.
5756 (bfd_som_set_subsection_attributes): Likewise.
5757 (som_is_space, som_is_subspace, som_is_container): New functions.
5758 Use these instead of directly accessing private data.
5759 (som_prep_headers): Allocate space and subspace headers here.
5760 Fill in some fields in the space/subspace headers from the
5762 (som_bfd_copy_private_section_data): Only copy the stuff
5763 that we really need to make objcopy and strip work. Allocate
5764 the copy_data structure for the output bfd before copying.
5766 * som.h (struct som_exec_data): New structure to hold exec
5767 info that must be preserved when running objcopy/strip.
5768 (struct somdata): Add new "exec_data" field and accessor
5769 macro. Add some comments on how the various fields are used.
5770 (som_section_data_struct): Make is_space and is_subspace bitfields.
5771 Delete unused subspace_index. All references now use the
5772 target_index field within the section structure itself.
5774 * som.c (make_unique_section): Delete unused declaration.
5775 (som_bfd_copy_private_bfd_data): New function.
5776 (som_object_setup): Allocate space for and save exec information
5777 that needs to be copied during objcopy/strip.
5778 (som_mkobject): Do not allocate space for a file header here.
5779 It is not used when only reading SOM objects.
5780 (som_prep_headers): Allocate space for and attach a file header
5781 to the output bfd. For executables, use the saved system_id
5782 value rather than trying to guess the right value. Do not abort
5783 wwhen setting file_hdr->entry* for executables.
5784 (som_begin_writing): For executables, set the exec_entry and
5786 (som_copy_private_backend_section_data): Always return a value.
5788 * libhppa.h (PA_PAGESIZE): Define.
5790 * som.c (SOM_ALIGN): Define.
5791 (som_begin_writing): If writing an executable, initialize all
5792 fields in the exec header to zero. Update fields in the exec
5793 header as sizes of loadable subspaces are computed. Carefully
5794 preserve alignments when building executables. Actually write the
5795 exec after all the fields are filled in.
5797 * Better long-filename handling. Reads SOM ABI compliant extended
5798 names, but doesn't quite write compliant extended names yet.
5799 * som.c (som_slurp_extended_name_table): Delete function. The
5800 generic code will handle things correctly.
5801 (som_slurp_armap): Seek to the beginning of the next member.
5802 (normalize): New function.
5803 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5804 name table into account when computing the file offsets in the
5805 SOM dictionary. Make sure to align to an even boundary.
5806 (som_write_armap): Initialize the checksum to zero.
5807 (ar_maxchars): Fix. Opps.
5809 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5811 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5812 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5814 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5816 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5817 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5818 * bfd-in2.h: Regenerated.
5820 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5821 this was also named trad_unix_bfd_copy_private_bfd_data.
5823 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5825 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5826 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5827 returns NULL, it is not an error. It's possible that some of
5828 these checks are not necessary (because the size can never be
5829 zero), but putting in the checks is the conservative thing to do
5830 in light of the fact that some of these malloc calls replaced
5831 unchecked alloca calls, in which a zero argument would work fine.
5833 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5835 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5836 duplicate definition.
5837 (osf_core_bfd_is_local_label): Define.
5839 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5840 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5841 failure indication, it merely means there are no relocs.
5843 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5844 after NAME, since SunOS /bin/cc can't handle it.
5846 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5848 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5849 From sukes@glue.umd.edu (Tasuki Hirata).
5851 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5853 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5854 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5855 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5857 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5859 * som.c (som_prep_for_fixups): Detect section symbols based
5860 on either the lack of private data or the symbol flags. Do not
5861 munge section symbol names anymore -- they no longer confuse GDB.
5862 (som_begin_writing): Leave space for an exec header if writing
5864 (som_slurp_symbol_table): Recognize both forms of section symbol
5865 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5866 section symbols to be the name of the section they represent.
5867 Debugging symbols begin with "L$0\001", not just "L$".
5869 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5871 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5873 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5874 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5875 and bfd_is_local_label.
5877 * targets.c: Add new entries to the bfd_target structure.
5879 * bfd.c (bfd_copy_private_bfd_data): New definition.
5881 * section.c (bfd_copy_private_section_data): New definition.
5883 * syms.c (bfd_is_local_label): New definition.
5885 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5887 * libbfd.c (bfd_generic_is_local_label): New function.
5889 * *-core.c: Provide default definitions for new functions in
5890 the target vector which all point to bfd_false.
5892 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5893 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5894 Default new vectors for copying private backend data to bfd_true.
5895 Default new vector for determining if a symbol is a local label
5896 to bfd_generic_is_local_label.
5898 * som.c (som_bfd_copy_private_section_data): New function.
5899 (som_bfd_is_local_label): New function.
5900 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5902 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5904 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5906 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5908 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5911 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5912 Indent some of them to GNU standards.
5914 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5915 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5916 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5917 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5918 Update copyright years.
5920 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5922 * som.c (som_prep_for_fixups): A relocation involving the section
5923 symbol for the *ABS* section is really a relocation involving
5925 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5926 undefined symbols. Correctly distinguish between debugger symbols
5927 and section symbols.
5929 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5930 for spaces and subspaces.
5932 * som.c (som_bfd_count_ar_symbols): Fix typo.
5934 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5935 HAS_RELOC based on the object's magic number.
5936 (make_unique_section): Delete function. BFD and its users are
5937 prepared to handle multiple sections with the same name.
5938 (setup_sections): Allocate space on the BFD's obstack to hold
5939 section names. Use bfd_make_setion_anyway rather than the
5940 obsolete make_unique_section.
5941 (som_prep_headers): Choose the correct SOM magic number based
5943 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5945 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5947 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5948 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5949 * Makefile.in, configure.in: Corresponding changes.
5951 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5953 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5955 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5957 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5958 is always located at the start of the data section to allow
5959 recovery of the dynamic info from a stripped executable.
5960 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5963 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5965 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5966 cruft (like the #pragma alloca for AIX).
5967 In addition to that problem, the C alloca calls xmalloc, which
5968 means checking for being out of memory can't work right. The
5969 following changes remove all uses of alloca from BFD.
5970 * hosts/solaris2.h: Remove alloca cruft.
5971 * som.c: Replace alloca with a fixed size auto array.
5972 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5973 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5974 sunos.c: Replace alloca with malloc and appropriate error checking and
5976 * linker.c: Replace alloca with obstack_alloc.
5977 * libbfd.h: Rebuilt.
5979 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5981 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5984 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5986 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5987 Elf*_Off typedefs by their expansion, the typedefs have been
5988 removed from include/elf/internal.h.
5989 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5990 SHT_PROGBITS section.
5992 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5994 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5998 * configure.host: Recognize i[34]86-sequent-*.
6000 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6001 return from bfd_seek indicates an error.
6002 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6003 TRAD_CORE_STACK_OFFSET.
6004 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6005 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6007 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6009 * som.[ch]: Do not include libhppa.h in som.c, instead include
6012 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6013 include it in elf32-hppa.h.
6015 * som.c (log2): Return -1 on error rather than aborting.
6016 (setup_sections): Bubble up an error from log2.
6018 * Changes to make HP C compiler happy in both traditional
6020 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6022 (bfd_som_set_section_attributes): Use unsigned int rather than
6023 unsigned char to avoid GNU-C extensions.
6024 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6025 or failure rather than aborting on failure.
6027 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6029 (bfd_som_attach_aux_hdr): Add prototype.
6030 (hppa_som-gen_reloc_type): Likewise.
6032 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6033 (hppa_look_for_stubs_in_section): Do not return false on failure
6034 until rest of code is ready to handle it. Abort for now.

6038 * bfd-in2.h: Rebuilt.
6040 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
6042 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

6046 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
6048 * config.bfd : Add i386-os9k.
6049 * config/i386-os9k.mt : Newly add os9k target makefile.
6051 * i386os9k.c : new file to handle os9k format bfd.
6052 * Makefile.in : Handle new file i386os9k.c
6053 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
6054 * cache.c : Initialize cache_sentinel to 0.

6058 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
6059 action in case where caller specified no argument relocation.
6060 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6061 right in the original relocation and the stub's relocation.
6063 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
6064 unused symbols argument.
6066 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
6067 than asymbol * for original target symbol. All callers changed.
6068 Set reloc->sym_ptr_ptr appropriately.
6069 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6070 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6071 argument. Use the output symbols when canonicalizing the relocs,
6072 creating them if necessary.
6074 * linker.c (_bfd_generic_link_output_symbols): Do not
6075 rebuild/clobber the output symbols if they already exist.
6077 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6079 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
6080 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
6081 * bfd-in2.h: Rebuilt.
6083 * srec.c (hex_value): Always set to a size of 256 bytes.
6084 (srec_init): Cosmetic changes.
6086 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6088 * elf32-hppa.c: Second half of major cleanup. More comments,
6089 PARAMize and staticize rest of functions. Delete unused
6090 functions. Delete unused/unnecessary arguments to some functions.
6091 Group static vars together. Abort for bad errors until we have
6092 error code propogation working. Work on spacing and indention.
6093 Add FIXMEs for unresolved problems. Use enums rather than
6094 #defines for lots of things. Merge two functions which build
6095 linker stubs into a single function (so they can easily share a
6096 ton of common code).
6098 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
6100 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
6101 avoid depending upon right shifts of signed numbers, and to
6102 correct handling of src_mask with lower bits zero.
6104 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
6105 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

6112 (write_shdrs_and_ehdr): Make count unsigned.
6113 (assign_file_positions_for_relocs): Make i unsigned.
6114 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
6115 (section_from_elf_index): Make index argument unsigned.
6117 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
6119 * elfcode.h: Don't include assert.h.
6120 (swap_out_syms): Use BFD_ASSERT rather than assert.

6125 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
6128 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6130 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
6132 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
6133 (elf_hppa_tc_make_sections): Likewise.
6134 (elf_hppa_final_processing): Add extern decl.
6136 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
6137 comments. PARAMize some static functions. Delete unused functions.
6138 Delete unused/unnecessary arguments to many functions. Group
6139 static vars together. Collapse common case statements together
6140 in many places. Use default case when possible instead of listing

6994 use get_value to get the symbol value and check for undefined
6996 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6997 undefined, look it up in the linker hash table.
6999 * aoutx.h (translate_symbol_table): The string index 0 has a

7024 The sparc (and possibly other?) NLM format requires a different
7025 way to write exports, so add a write_export field to the backend
