2293 .plt section. Call elf32_sparc_create_got_section rather than
2294 creating the .got section.

2296 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.

2298 reloc, for a global symbol or when generating a shared object.

2305 of the .plt section.

2311 symbol when no dynamic object was seen, initialize the contents of
2312 the .got section. For a GOT reloc against a local symbol, only
2313 create a R_SPARC_RELATIVE reloc when generating a shared object.
2314 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
2315 create a PLT entry as a R_SPARC_WDISP30 reloc.
2316 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
2317 dynamic entries and the PLT if we saw a dynamic object.

5701 * som.c (som_begin_writing): New approach at dealing with holes
5702 in executables left by the HP linker. Does not rely on subspace
5703 alignments as subspaces are *NOT* guaranteed to be properly
5704 aligned in an executable (can you believe that!).
5706 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5708 * som.c (som_get_section_contents): New function. Do not try

5754 required by expansions. Set s and unset h when converting a reloc
5755 from undefined to section. Change handling of PC relative relocs:
5756 if against a section, they are correct in the object file, if
5757 against an external symbol they are pcrel_offset.
5758 (mips_relax_section): New function.
5759 (mips_relax_pcrel16): New function.
5760 (ecoff_bfd_relax_section): Define.

5844 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
5845 reloc, used in embedded PIC code.
5846 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
5847 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

5853 link_order loop. Use _bfd_generic_link_add_symbols_collect for
5854 add_symbls entry point.
5856 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5857 counting relocs. Set SEC_RELOC flag for any section which has

5885 extended name table.
5887 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5889 Support for link_order types which generate relocs in order to
5890 support -Ur in the linker.
5891 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5892 from call to _bfd_generic_link_add_one_symbol.
5893 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5894 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5895 instead of bitsize to add_to_set call back.
5896 (_bfd_generic_final_link): Account for link_order relocs when
5897 allocating space for relocations. Handle them in link_order loop.
5898 (_bfd_generic_reloc_link_order): New function.

5915 (ecoff_bfd_final_link): Account for link_order relocs when
5916 allocating space for relocations. Handle them in link_order loop.
5917 (ecoff_link_write_external): Set the storage class of a defined
5918 linker created symbol based on the section it is in. Correct
5919 bfd_link_hash_weak case to use .sc rather than .st.
5920 (ecoff_reloc_link_order): New function.
5921 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5923 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5929 bfd_zmalloc. Free a pointer, not a union.
5930 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5932 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5934 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5936 * som.c (bfd_section_from_som_symbol): Only to do the value
5937 comparison for function symbols within executables.
5939 * som.c (bfd_section_from_som_symbol): Renamed from
5940 som_section_from_subspace_index. Pass in a native SOM symbol.
5941 For executables, iterate through the sections to find out
5942 which contains the symbol's address rather than using the
5943 symbol_info field. (symbol_info has a different meaning for
5944 dynamicly linked executables.)
5946 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5949 * som.c (som_begin_writing): Fix braino (one call to align
5950 space/subspace data was done unconditionally rather than
5951 just for executables.)
5953 * som.c (som_begin_writing): Align text in all executables to
5954 make HPUX kernel happy. Fixes strip/objcopy for shared
5957 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5959 * som.c (som_begin_writing): Account for alignment needs of
5960 subspaces too when writing executables. Never request a negative
5961 bss size. Fixes some problems with demand paged executables,
5962 still having problems with pure executables and shared executables.
5964 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5966 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5967 bfd_zalloc for rawptr, because later on we may call free, not
5970 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5971 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5972 * cisco-core.c: New file.
5973 * Makefile.in: Change accordingly.
5974 * configure.in: Recognize cisco_core_vec.
5975 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5976 * targets.c: Add cisco_core_vec.
5977 * bfd-in2.h: Rebuilt.
5979 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5981 * som.h (som_copyable_section_data_struct): New structure
5982 containing all the private section information which needs
5983 to be copied from input section to output section during
5985 (som_section_data_struct): Remove several fields now in
5986 som_copyable_section_data_struct. Make the space and
5987 subspace dictionaries be pointers (to save space when
5988 only reading objects).
5990 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5991 some references changed. Allocate a copyable data stucture if
5992 none exists. Store info into the copyable data structure.
5993 (bfd_som_set_subsection_attributes): Likewise.
5994 (som_is_space, som_is_subspace, som_is_container): New functions.
5995 Use these instead of directly accessing private data.
5996 (som_prep_headers): Allocate space and subspace headers here.
5997 Fill in some fields in the space/subspace headers from the
5999 (som_bfd_copy_private_section_data): Only copy the stuff
6000 that we really need to make objcopy and strip work. Allocate
6001 the copy_data structure for the output bfd before copying.
6003 * som.h (struct som_exec_data): New structure to hold exec
6004 info that must be preserved when running objcopy/strip.
6005 (struct somdata): Add new "exec_data" field and accessor
6006 macro. Add some comments on how the various fields are used.
6007 (som_section_data_struct): Make is_space and is_subspace bitfields.
6008 Delete unused subspace_index. All references now use the
6009 target_index field within the section structure itself.
6011 * som.c (make_unique_section): Delete unused declaration.
6012 (som_bfd_copy_private_bfd_data): New function.
6013 (som_object_setup): Allocate space for and save exec information
6014 that needs to be copied during objcopy/strip.
6015 (som_mkobject): Do not allocate space for a file header here.
6016 It is not used when only reading SOM objects.
6017 (som_prep_headers): Allocate space for and attach a file header
6018 to the output bfd. For executables, use the saved system_id
6019 value rather than trying to guess the right value. Do not abort
6020 wwhen setting file_hdr->entry* for executables.
6021 (som_begin_writing): For executables, set the exec_entry and
6023 (som_copy_private_backend_section_data): Always return a value.
6025 * libhppa.h (PA_PAGESIZE): Define.
6027 * som.c (SOM_ALIGN): Define.
6028 (som_begin_writing): If writing an executable, initialize all
6029 fields in the exec header to zero. Update fields in the exec
6030 header as sizes of loadable subspaces are computed. Carefully
6031 preserve alignments when building executables. Actually write the
6032 exec after all the fields are filled in.
6034 * Better long-filename handling. Reads SOM ABI compliant extended
6035 names, but doesn't quite write compliant extended names yet.
6036 * som.c (som_slurp_extended_name_table): Delete function. The
6037 generic code will handle things correctly.
6038 (som_slurp_armap): Seek to the beginning of the next member.
6039 (normalize): New function.
6040 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6041 name table into account when computing the file offsets in the
6042 SOM dictionary. Make sure to align to an even boundary.
6043 (som_write_armap): Initialize the checksum to zero.
6044 (ar_maxchars): Fix. Opps.
6046 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6048 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6049 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6051 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6053 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6054 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6055 * bfd-in2.h: Regenerated.
6057 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6058 this was also named trad_unix_bfd_copy_private_bfd_data.
6060 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6062 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6063 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6064 returns NULL, it is not an error. It's possible that some of
6065 these checks are not necessary (because the size can never be
6066 zero), but putting in the checks is the conservative thing to do
6067 in light of the fact that some of these malloc calls replaced
6068 unchecked alloca calls, in which a zero argument would work fine.
6070 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6072 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6073 duplicate definition.
6074 (osf_core_bfd_is_local_label): Define.
6076 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6077 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6078 failure indication, it merely means there are no relocs.
6080 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6081 after NAME, since SunOS /bin/cc can't handle it.
6083 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6085 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6086 From sukes@glue.umd.edu (Tasuki Hirata).
6088 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6090 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6091 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6092 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6094 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6096 * som.c (som_prep_for_fixups): Detect section symbols based
6097 on either the lack of private data or the symbol flags. Do not
6098 munge section symbol names anymore -- they no longer confuse GDB.
6099 (som_begin_writing): Leave space for an exec header if writing
6101 (som_slurp_symbol_table): Recognize both forms of section symbol
6102 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6103 section symbols to be the name of the section they represent.
6104 Debugging symbols begin with "L$0\001", not just "L$".
6106 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6108 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6110 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6111 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6112 and bfd_is_local_label.
6114 * targets.c: Add new entries to the bfd_target structure.
6116 * bfd.c (bfd_copy_private_bfd_data): New definition.
6118 * section.c (bfd_copy_private_section_data): New definition.

7234 undefined, look it up in the linker hash table.
7236 * aoutx.h (translate_symbol_table): The string index 0 has a

7261 The sparc (and possibly other?) NLM format requires a different
7262 way to write exports, so add a write_export field to the backend
7263 data (and set it to NULL for everything but the sparc).
