5729 from undefined to section. Change handling of PC relative relocs:
5730 if against a section, they are correct in the object file, if
5731 against an external symbol they are pcrel_offset.
5732 (mips_relax_section): New function.
5733 (mips_relax_pcrel16): New function.
5734 (ecoff_bfd_relax_section): Define.

5859 extended name table.
5861 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5863 Support for link_order types which generate relocs in order to
5864 support -Ur in the linker.
5865 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5866 from call to _bfd_generic_link_add_one_symbol.
5867 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5868 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5869 instead of bitsize to add_to_set call back.
5870 (_bfd_generic_final_link): Account for link_order relocs when
5871 allocating space for relocations. Handle them in link_order loop.
5872 (_bfd_generic_reloc_link_order): New function.

5890 allocating space for relocations. Handle them in link_order loop.
5891 (ecoff_link_write_external): Set the storage class of a defined
5892 linker created symbol based on the section it is in. Correct
5893 bfd_link_hash_weak case to use .sc rather than .st.
5894 (ecoff_reloc_link_order): New function.
5895 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5897 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5903 bfd_zmalloc. Free a pointer, not a union.
5904 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5906 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5908 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5910 * som.c (bfd_section_from_som_symbol): Only to do the value
5911 comparison for function symbols within executables.
5913 * som.c (bfd_section_from_som_symbol): Renamed from
5914 som_section_from_subspace_index. Pass in a native SOM symbol.
5915 For executables, iterate through the sections to find out
5916 which contains the symbol's address rather than using the
5917 symbol_info field. (symbol_info has a different meaning for
5918 dynamicly linked executables.)
5920 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5923 * som.c (som_begin_writing): Fix braino (one call to align
5924 space/subspace data was done unconditionally rather than
5925 just for executables.)
5927 * som.c (som_begin_writing): Align text in all executables to
5928 make HPUX kernel happy. Fixes strip/objcopy for shared
5931 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5933 * som.c (som_begin_writing): Account for alignment needs of
5934 subspaces too when writing executables. Never request a negative
5935 bss size. Fixes some problems with demand paged executables,
5936 still having problems with pure executables and shared executables.
5938 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5940 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5941 bfd_zalloc for rawptr, because later on we may call free, not
5944 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5945 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5946 * cisco-core.c: New file.

5953 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5955 * som.h (som_copyable_section_data_struct): New structure
5956 containing all the private section information which needs
5957 to be copied from input section to output section during
5959 (som_section_data_struct): Remove several fields now in
5960 som_copyable_section_data_struct. Make the space and
5961 subspace dictionaries be pointers (to save space when
5962 only reading objects).
5964 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5965 some references changed. Allocate a copyable data stucture if
5966 none exists. Store info into the copyable data structure.
5967 (bfd_som_set_subsection_attributes): Likewise.
5968 (som_is_space, som_is_subspace, som_is_container): New functions.
5969 Use these instead of directly accessing private data.
5970 (som_prep_headers): Allocate space and subspace headers here.
5971 Fill in some fields in the space/subspace headers from the
5973 (som_bfd_copy_private_section_data): Only copy the stuff
5974 that we really need to make objcopy and strip work. Allocate
5975 the copy_data structure for the output bfd before copying.
5977 * som.h (struct som_exec_data): New structure to hold exec
5978 info that must be preserved when running objcopy/strip.
5979 (struct somdata): Add new "exec_data" field and accessor
5980 macro. Add some comments on how the various fields are used.
5981 (som_section_data_struct): Make is_space and is_subspace bitfields.
5982 Delete unused subspace_index. All references now use the
5983 target_index field within the section structure itself.
5985 * som.c (make_unique_section): Delete unused declaration.
5986 (som_bfd_copy_private_bfd_data): New function.
5987 (som_object_setup): Allocate space for and save exec information
5988 that needs to be copied during objcopy/strip.
5989 (som_mkobject): Do not allocate space for a file header here.
5990 It is not used when only reading SOM objects.
5991 (som_prep_headers): Allocate space for and attach a file header
5992 to the output bfd. For executables, use the saved system_id
5993 value rather than trying to guess the right value. Do not abort
5994 wwhen setting file_hdr->entry* for executables.
5995 (som_begin_writing): For executables, set the exec_entry and
5997 (som_copy_private_backend_section_data): Always return a value.
5999 * libhppa.h (PA_PAGESIZE): Define.
6001 * som.c (SOM_ALIGN): Define.
6002 (som_begin_writing): If writing an executable, initialize all
6003 fields in the exec header to zero. Update fields in the exec
6004 header as sizes of loadable subspaces are computed. Carefully
6005 preserve alignments when building executables. Actually write the
6006 exec after all the fields are filled in.
6008 * Better long-filename handling. Reads SOM ABI compliant extended
6009 names, but doesn't quite write compliant extended names yet.
6010 * som.c (som_slurp_extended_name_table): Delete function. The
6011 generic code will handle things correctly.
6012 (som_slurp_armap): Seek to the beginning of the next member.
6013 (normalize): New function.
6014 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6015 name table into account when computing the file offsets in the
6016 SOM dictionary. Make sure to align to an even boundary.
6017 (som_write_armap): Initialize the checksum to zero.
6018 (ar_maxchars): Fix. Opps.
6020 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6022 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6023 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6025 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6027 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6028 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6029 * bfd-in2.h: Regenerated.
6031 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6032 this was also named trad_unix_bfd_copy_private_bfd_data.
6034 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6036 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6037 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6038 returns NULL, it is not an error. It's possible that some of
6039 these checks are not necessary (because the size can never be
6040 zero), but putting in the checks is the conservative thing to do
6041 in light of the fact that some of these malloc calls replaced
6042 unchecked alloca calls, in which a zero argument would work fine.
6044 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6046 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6047 duplicate definition.
6048 (osf_core_bfd_is_local_label): Define.
6050 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6051 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6052 failure indication, it merely means there are no relocs.
6054 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6055 after NAME, since SunOS /bin/cc can't handle it.
6057 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6059 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6060 From sukes@glue.umd.edu (Tasuki Hirata).
6062 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6064 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6065 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6066 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6068 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6070 * som.c (som_prep_for_fixups): Detect section symbols based
6071 on either the lack of private data or the symbol flags. Do not
6072 munge section symbol names anymore -- they no longer confuse GDB.
6073 (som_begin_writing): Leave space for an exec header if writing
6075 (som_slurp_symbol_table): Recognize both forms of section symbol
6076 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6077 section symbols to be the name of the section they represent.
6078 Debugging symbols begin with "L$0\001", not just "L$".
6080 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6082 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6084 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6085 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6086 and bfd_is_local_label.
6088 * targets.c: Add new entries to the bfd_target structure.

6101 the target vector which all point to bfd_false.
6103 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6104 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6105 Default new vectors for copying private backend data to bfd_true.
6106 Default new vector for determining if a symbol is a local label
6107 to bfd_generic_is_local_label.
6109 * som.c (som_bfd_copy_private_section_data): New function.
6110 (som_bfd_is_local_label): New function.
6111 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6113 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6115 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6117 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6119 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)

6177 cruft (like the #pragma alloca for AIX).
6178 In addition to that problem, the C alloca calls xmalloc, which

7235 The sparc (and possibly other?) NLM format requires a different
7236 way to write exports, so add a write_export field to the backend
7237 data (and set it to NULL for everything but the sparc).
