5684 aligned in an executable (can you believe that!).
5686 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5688 * som.c (som_get_section_contents): New function. Do not try

5696 failing bfd_read, bfd_write, or bfd_seek. In a few places
5697 (like som_object_p) override the error status set by bfd_read.

5734 required by expansions. Set s and unset h when converting a reloc
5735 from undefined to section. Change handling of PC relative relocs:
5736 if against a section, they are correct in the object file, if
5737 against an external symbol they are pcrel_offset.
5738 (mips_relax_section): New function.
5739 (mips_relax_pcrel16): New function.
5740 (ecoff_bfd_relax_section): Define.

5825 reloc, used in embedded PIC code.
5826 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
5827 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

5834 add_symbls entry point.
5836 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5837 counting relocs. Set SEC_RELOC flag for any section which has

5865 extended name table.
5867 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5869 Support for link_order types which generate relocs in order to
5870 support -Ur in the linker.
5871 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5872 from call to _bfd_generic_link_add_one_symbol.
5873 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5874 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5875 instead of bitsize to add_to_set call back.
5876 (_bfd_generic_final_link): Account for link_order relocs when
5877 allocating space for relocations. Handle them in link_order loop.
5878 (_bfd_generic_reloc_link_order): New function.

5895 (ecoff_bfd_final_link): Account for link_order relocs when
5896 allocating space for relocations. Handle them in link_order loop.
5897 (ecoff_link_write_external): Set the storage class of a defined
5898 linker created symbol based on the section it is in. Correct
5899 bfd_link_hash_weak case to use .sc rather than .st.
5900 (ecoff_reloc_link_order): New function.
5901 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5903 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5908 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5909 bfd_zmalloc. Free a pointer, not a union.
5910 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5912 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5914 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5916 * som.c (bfd_section_from_som_symbol): Only to do the value
5917 comparison for function symbols within executables.
5919 * som.c (bfd_section_from_som_symbol): Renamed from
5920 som_section_from_subspace_index. Pass in a native SOM symbol.
5921 For executables, iterate through the sections to find out
5922 which contains the symbol's address rather than using the
5923 symbol_info field. (symbol_info has a different meaning for
5924 dynamicly linked executables.)
5926 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5929 * som.c (som_begin_writing): Fix braino (one call to align
5930 space/subspace data was done unconditionally rather than
5931 just for executables.)
5933 * som.c (som_begin_writing): Align text in all executables to
5934 make HPUX kernel happy. Fixes strip/objcopy for shared
5937 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5939 * som.c (som_begin_writing): Account for alignment needs of
5940 subspaces too when writing executables. Never request a negative
5941 bss size. Fixes some problems with demand paged executables,
5942 still having problems with pure executables and shared executables.
5944 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5946 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5947 bfd_zalloc for rawptr, because later on we may call free, not
5950 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5951 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5952 * cisco-core.c: New file.
5953 * Makefile.in: Change accordingly.
5954 * configure.in: Recognize cisco_core_vec.
5955 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5956 * targets.c: Add cisco_core_vec.
5957 * bfd-in2.h: Rebuilt.
5959 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5961 * som.h (som_copyable_section_data_struct): New structure
5962 containing all the private section information which needs
5963 to be copied from input section to output section during
5965 (som_section_data_struct): Remove several fields now in
5966 som_copyable_section_data_struct. Make the space and
5967 subspace dictionaries be pointers (to save space when
5968 only reading objects).
5970 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5971 some references changed. Allocate a copyable data stucture if
5972 none exists. Store info into the copyable data structure.
5973 (bfd_som_set_subsection_attributes): Likewise.
5974 (som_is_space, som_is_subspace, som_is_container): New functions.
5975 Use these instead of directly accessing private data.
5976 (som_prep_headers): Allocate space and subspace headers here.
5977 Fill in some fields in the space/subspace headers from the
5979 (som_bfd_copy_private_section_data): Only copy the stuff
5980 that we really need to make objcopy and strip work. Allocate
5981 the copy_data structure for the output bfd before copying.
5983 * som.h (struct som_exec_data): New structure to hold exec
5984 info that must be preserved when running objcopy/strip.
5985 (struct somdata): Add new "exec_data" field and accessor
5986 macro. Add some comments on how the various fields are used.
5987 (som_section_data_struct): Make is_space and is_subspace bitfields.
5988 Delete unused subspace_index. All references now use the
5989 target_index field within the section structure itself.
5991 * som.c (make_unique_section): Delete unused declaration.
5992 (som_bfd_copy_private_bfd_data): New function.
5993 (som_object_setup): Allocate space for and save exec information
5994 that needs to be copied during objcopy/strip.
5995 (som_mkobject): Do not allocate space for a file header here.
5996 It is not used when only reading SOM objects.
5997 (som_prep_headers): Allocate space for and attach a file header
5998 to the output bfd. For executables, use the saved system_id
5999 value rather than trying to guess the right value. Do not abort
6000 wwhen setting file_hdr->entry* for executables.
6001 (som_begin_writing): For executables, set the exec_entry and
6003 (som_copy_private_backend_section_data): Always return a value.
6005 * libhppa.h (PA_PAGESIZE): Define.
6007 * som.c (SOM_ALIGN): Define.
6008 (som_begin_writing): If writing an executable, initialize all
6009 fields in the exec header to zero. Update fields in the exec
6010 header as sizes of loadable subspaces are computed. Carefully
6011 preserve alignments when building executables. Actually write the
6012 exec after all the fields are filled in.
6014 * Better long-filename handling. Reads SOM ABI compliant extended
6015 names, but doesn't quite write compliant extended names yet.
6016 * som.c (som_slurp_extended_name_table): Delete function. The
6017 generic code will handle things correctly.
6018 (som_slurp_armap): Seek to the beginning of the next member.
6019 (normalize): New function.
6020 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6021 name table into account when computing the file offsets in the
6022 SOM dictionary. Make sure to align to an even boundary.
6023 (som_write_armap): Initialize the checksum to zero.
6024 (ar_maxchars): Fix. Opps.
6026 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6028 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6029 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6031 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6033 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6034 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6035 * bfd-in2.h: Regenerated.
6037 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6038 this was also named trad_unix_bfd_copy_private_bfd_data.
6040 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6042 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6043 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6044 returns NULL, it is not an error. It's possible that some of
6045 these checks are not necessary (because the size can never be
6046 zero), but putting in the checks is the conservative thing to do
6047 in light of the fact that some of these malloc calls replaced
6048 unchecked alloca calls, in which a zero argument would work fine.
6050 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6052 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6053 duplicate definition.
6054 (osf_core_bfd_is_local_label): Define.
6056 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6057 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6058 failure indication, it merely means there are no relocs.
6060 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6061 after NAME, since SunOS /bin/cc can't handle it.
6063 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6065 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6066 From sukes@glue.umd.edu (Tasuki Hirata).
6068 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6070 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6071 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6072 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6074 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6076 * som.c (som_prep_for_fixups): Detect section symbols based
6077 on either the lack of private data or the symbol flags. Do not
6078 munge section symbol names anymore -- they no longer confuse GDB.
6079 (som_begin_writing): Leave space for an exec header if writing
6081 (som_slurp_symbol_table): Recognize both forms of section symbol
6082 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6083 section symbols to be the name of the section they represent.
6084 Debugging symbols begin with "L$0\001", not just "L$".
6086 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6088 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6090 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6091 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6092 and bfd_is_local_label.
6094 * targets.c: Add new entries to the bfd_target structure.
6096 * bfd.c (bfd_copy_private_bfd_data): New definition.

6107 the target vector which all point to bfd_false.
6109 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6110 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6111 Default new vectors for copying private backend data to bfd_true.
6112 Default new vector for determining if a symbol is a local label
6113 to bfd_generic_is_local_label.
6115 * som.c (som_bfd_copy_private_section_data): New function.
6116 (som_bfd_is_local_label): New function.
6117 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6119 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6121 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

6183 cruft (like the #pragma alloca for AIX).
6184 In addition to that problem, the C alloca calls xmalloc, which

7214 undefined, look it up in the linker hash table.
7216 * aoutx.h (translate_symbol_table): The string index 0 has a

7241 The sparc (and possibly other?) NLM format requires a different
7242 way to write exports, so add a write_export field to the backend
7243 data (and set it to NULL for everything but the sparc).
