5688 in executables left by the HP linker. Does not rely on subspace
5689 alignments as subspaces are *NOT* guaranteed to be properly
5690 aligned in an executable (can you believe that!).
5692 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5694 * som.c (som_get_section_contents): New function. Do not try

5702 failing bfd_read, bfd_write, or bfd_seek. In a few places
5703 (like som_object_p) override the error status set by bfd_read.

5740 required by expansions. Set s and unset h when converting a reloc
5741 from undefined to section. Change handling of PC relative relocs:
5742 if against a section, they are correct in the object file, if
5743 against an external symbol they are pcrel_offset.
5744 (mips_relax_section): New function.
5745 (mips_relax_pcrel16): New function.

5828 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5830 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
5831 reloc, used in embedded PIC code.
5832 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
5833 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

5839 link_order loop. Use _bfd_generic_link_add_symbols_collect for
5840 add_symbls entry point.
5842 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5843 counting relocs. Set SEC_RELOC flag for any section which has

5871 extended name table.
5873 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5875 Support for link_order types which generate relocs in order to
5876 support -Ur in the linker.
5877 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5878 from call to _bfd_generic_link_add_one_symbol.
5879 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5880 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5881 instead of bitsize to add_to_set call back.
5882 (_bfd_generic_final_link): Account for link_order relocs when
5883 allocating space for relocations. Handle them in link_order loop.
5884 (_bfd_generic_reloc_link_order): New function.

5889 argument from declaration.
5890 (_bfd_generic_reloc_link_order): Declare.

5901 (ecoff_bfd_final_link): Account for link_order relocs when
5902 allocating space for relocations. Handle them in link_order loop.
5903 (ecoff_link_write_external): Set the storage class of a defined
5904 linker created symbol based on the section it is in. Correct
5905 bfd_link_hash_weak case to use .sc rather than .st.
5906 (ecoff_reloc_link_order): New function.
5907 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5909 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5914 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5915 bfd_zmalloc. Free a pointer, not a union.
5916 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5918 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5920 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5922 * som.c (bfd_section_from_som_symbol): Only to do the value
5923 comparison for function symbols within executables.
5925 * som.c (bfd_section_from_som_symbol): Renamed from
5926 som_section_from_subspace_index. Pass in a native SOM symbol.
5927 For executables, iterate through the sections to find out
5928 which contains the symbol's address rather than using the
5929 symbol_info field. (symbol_info has a different meaning for
5930 dynamicly linked executables.)
5932 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5935 * som.c (som_begin_writing): Fix braino (one call to align
5936 space/subspace data was done unconditionally rather than
5937 just for executables.)
5939 * som.c (som_begin_writing): Align text in all executables to
5940 make HPUX kernel happy. Fixes strip/objcopy for shared
5943 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5945 * som.c (som_begin_writing): Account for alignment needs of
5946 subspaces too when writing executables. Never request a negative
5947 bss size. Fixes some problems with demand paged executables,
5948 still having problems with pure executables and shared executables.
5950 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5952 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5953 bfd_zalloc for rawptr, because later on we may call free, not
5956 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5957 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5958 * cisco-core.c: New file.
5959 * Makefile.in: Change accordingly.
5960 * configure.in: Recognize cisco_core_vec.
5961 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5962 * targets.c: Add cisco_core_vec.
5963 * bfd-in2.h: Rebuilt.
5965 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5967 * som.h (som_copyable_section_data_struct): New structure
5968 containing all the private section information which needs
5969 to be copied from input section to output section during
5971 (som_section_data_struct): Remove several fields now in
5972 som_copyable_section_data_struct. Make the space and
5973 subspace dictionaries be pointers (to save space when
5974 only reading objects).
5976 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5977 some references changed. Allocate a copyable data stucture if
5978 none exists. Store info into the copyable data structure.
5979 (bfd_som_set_subsection_attributes): Likewise.
5980 (som_is_space, som_is_subspace, som_is_container): New functions.
5981 Use these instead of directly accessing private data.
5982 (som_prep_headers): Allocate space and subspace headers here.
5983 Fill in some fields in the space/subspace headers from the
5985 (som_bfd_copy_private_section_data): Only copy the stuff
5986 that we really need to make objcopy and strip work. Allocate
5987 the copy_data structure for the output bfd before copying.
5989 * som.h (struct som_exec_data): New structure to hold exec
5990 info that must be preserved when running objcopy/strip.
5991 (struct somdata): Add new "exec_data" field and accessor
5992 macro. Add some comments on how the various fields are used.
5993 (som_section_data_struct): Make is_space and is_subspace bitfields.
5994 Delete unused subspace_index. All references now use the
5995 target_index field within the section structure itself.
5997 * som.c (make_unique_section): Delete unused declaration.
5998 (som_bfd_copy_private_bfd_data): New function.
5999 (som_object_setup): Allocate space for and save exec information
6000 that needs to be copied during objcopy/strip.
6001 (som_mkobject): Do not allocate space for a file header here.
6002 It is not used when only reading SOM objects.
6003 (som_prep_headers): Allocate space for and attach a file header
6004 to the output bfd. For executables, use the saved system_id
6005 value rather than trying to guess the right value. Do not abort
6006 wwhen setting file_hdr->entry* for executables.
6007 (som_begin_writing): For executables, set the exec_entry and
6009 (som_copy_private_backend_section_data): Always return a value.
6011 * libhppa.h (PA_PAGESIZE): Define.
6013 * som.c (SOM_ALIGN): Define.
6014 (som_begin_writing): If writing an executable, initialize all
6015 fields in the exec header to zero. Update fields in the exec
6016 header as sizes of loadable subspaces are computed. Carefully
6017 preserve alignments when building executables. Actually write the
6018 exec after all the fields are filled in.
6020 * Better long-filename handling. Reads SOM ABI compliant extended
6021 names, but doesn't quite write compliant extended names yet.
6022 * som.c (som_slurp_extended_name_table): Delete function. The
6023 generic code will handle things correctly.
6024 (som_slurp_armap): Seek to the beginning of the next member.
6025 (normalize): New function.
6026 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6027 name table into account when computing the file offsets in the
6028 SOM dictionary. Make sure to align to an even boundary.
6029 (som_write_armap): Initialize the checksum to zero.
6030 (ar_maxchars): Fix. Opps.
6032 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6034 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6035 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6037 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6039 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6040 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6041 * bfd-in2.h: Regenerated.
6043 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6044 this was also named trad_unix_bfd_copy_private_bfd_data.
6046 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6048 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6049 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6050 returns NULL, it is not an error. It's possible that some of
6051 these checks are not necessary (because the size can never be
6052 zero), but putting in the checks is the conservative thing to do
6053 in light of the fact that some of these malloc calls replaced
6054 unchecked alloca calls, in which a zero argument would work fine.
6056 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6058 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6059 duplicate definition.
6060 (osf_core_bfd_is_local_label): Define.
6062 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6063 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6064 failure indication, it merely means there are no relocs.
6066 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6067 after NAME, since SunOS /bin/cc can't handle it.
6069 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6071 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6072 From sukes@glue.umd.edu (Tasuki Hirata).
6074 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6076 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6077 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6078 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6080 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6082 * som.c (som_prep_for_fixups): Detect section symbols based
6083 on either the lack of private data or the symbol flags. Do not
6084 munge section symbol names anymore -- they no longer confuse GDB.
6085 (som_begin_writing): Leave space for an exec header if writing
6087 (som_slurp_symbol_table): Recognize both forms of section symbol
6088 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6089 section symbols to be the name of the section they represent.
6090 Debugging symbols begin with "L$0\001", not just "L$".
6092 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6094 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6096 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6097 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6098 and bfd_is_local_label.
6100 * targets.c: Add new entries to the bfd_target structure.
6102 * bfd.c (bfd_copy_private_bfd_data): New definition.
6104 * section.c (bfd_copy_private_section_data): New definition.

6113 the target vector which all point to bfd_false.
6115 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6116 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6117 Default new vectors for copying private backend data to bfd_true.
6118 Default new vector for determining if a symbol is a local label
6119 to bfd_generic_is_local_label.
6121 * som.c (som_bfd_copy_private_section_data): New function.
6122 (som_bfd_is_local_label): New function.
6123 (som_bfd_copy_private_bfd_data): For now default to bfd_true.

6189 cruft (like the #pragma alloca for AIX).
6190 In addition to that problem, the C alloca calls xmalloc, which

7220 undefined, look it up in the linker hash table.
7222 * aoutx.h (translate_symbol_table): The string index 0 has a

7247 The sparc (and possibly other?) NLM format requires a different
7248 way to write exports, so add a write_export field to the backend
7249 data (and set it to NULL for everything but the sparc).
