2290 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
2291 Only create the .rela.got section, and only make space for a
2292 reloc, for a global symbol or when generating a shared object.
2293 Set the alignment of the .rela.got section to 2. For a
2294 R_SPARC_WPLT30 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.

2296 permit ELF_LINK_HASH_NEDS_PLT non dynamic symbols. Create a
2297 procedure linkage table for such symbols. But, if no dynamic

2299 of the .plt section.
2300 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
2301 seen, skip most of this function, and force the size of the

2305 symbol when no dynamic object was seen, initialize the contents of
2306 the .got section. For a GOT reloc against a local symbol, only
2307 create a R_SPARC_RELATIVE reloc when generating a shared object.
2308 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
2309 create a PLT entry as a R_SPARC_WDISP30 reloc.
2310 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
2311 dynamic entries and the PLT if we saw a dynamic object.

5696 in executables left by the HP linker. Does not rely on subspace
5697 alignments as subspaces are *NOT* guaranteed to be properly

5748 required by expansions. Set s and unset h when converting a reloc
5749 from undefined to section. Change handling of PC relative relocs:
5750 if against a section, they are correct in the object file, if
5751 against an external symbol they are pcrel_offset.
5752 (mips_relax_section): New function.
5753 (mips_relax_pcrel16): New function.
5754 (ecoff_bfd_relax_section): Define.

5839 reloc, used in embedded PIC code.
5840 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

5848 add_symbls entry point.
5850 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5851 counting relocs. Set SEC_RELOC flag for any section which has

5879 extended name table.
5881 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5883 Support for link_order types which generate relocs in order to
5884 support -Ur in the linker.
5885 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5886 from call to _bfd_generic_link_add_one_symbol.
5887 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5888 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5889 instead of bitsize to add_to_set call back.
5890 (_bfd_generic_final_link): Account for link_order relocs when
5891 allocating space for relocations. Handle them in link_order loop.
5892 (_bfd_generic_reloc_link_order): New function.

5909 (ecoff_bfd_final_link): Account for link_order relocs when
5910 allocating space for relocations. Handle them in link_order loop.
5911 (ecoff_link_write_external): Set the storage class of a defined
5912 linker created symbol based on the section it is in. Correct
5913 bfd_link_hash_weak case to use .sc rather than .st.
5914 (ecoff_reloc_link_order): New function.
5915 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5917 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5922 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5923 bfd_zmalloc. Free a pointer, not a union.
5924 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5926 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5928 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5930 * som.c (bfd_section_from_som_symbol): Only to do the value
5931 comparison for function symbols within executables.
5933 * som.c (bfd_section_from_som_symbol): Renamed from
5934 som_section_from_subspace_index. Pass in a native SOM symbol.
5935 For executables, iterate through the sections to find out
5936 which contains the symbol's address rather than using the
5937 symbol_info field. (symbol_info has a different meaning for
5938 dynamicly linked executables.)
5940 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5943 * som.c (som_begin_writing): Fix braino (one call to align
5944 space/subspace data was done unconditionally rather than
5945 just for executables.)
5947 * som.c (som_begin_writing): Align text in all executables to
5948 make HPUX kernel happy. Fixes strip/objcopy for shared
5951 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5953 * som.c (som_begin_writing): Account for alignment needs of
5954 subspaces too when writing executables. Never request a negative
5955 bss size. Fixes some problems with demand paged executables,
5956 still having problems with pure executables and shared executables.
5958 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5960 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5961 bfd_zalloc for rawptr, because later on we may call free, not
5964 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5965 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5966 * cisco-core.c: New file.
5967 * Makefile.in: Change accordingly.
5968 * configure.in: Recognize cisco_core_vec.
5969 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5970 * targets.c: Add cisco_core_vec.
5971 * bfd-in2.h: Rebuilt.
5973 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5975 * som.h (som_copyable_section_data_struct): New structure
5976 containing all the private section information which needs
5977 to be copied from input section to output section during
5979 (som_section_data_struct): Remove several fields now in
5980 som_copyable_section_data_struct. Make the space and
5981 subspace dictionaries be pointers (to save space when
5982 only reading objects).
5984 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5985 some references changed. Allocate a copyable data stucture if
5986 none exists. Store info into the copyable data structure.
5987 (bfd_som_set_subsection_attributes): Likewise.
5988 (som_is_space, som_is_subspace, som_is_container): New functions.
5989 Use these instead of directly accessing private data.
5990 (som_prep_headers): Allocate space and subspace headers here.
5991 Fill in some fields in the space/subspace headers from the
5993 (som_bfd_copy_private_section_data): Only copy the stuff
5994 that we really need to make objcopy and strip work. Allocate
5995 the copy_data structure for the output bfd before copying.
5997 * som.h (struct som_exec_data): New structure to hold exec
5998 info that must be preserved when running objcopy/strip.
5999 (struct somdata): Add new "exec_data" field and accessor
6000 macro. Add some comments on how the various fields are used.
6001 (som_section_data_struct): Make is_space and is_subspace bitfields.
6002 Delete unused subspace_index. All references now use the
6003 target_index field within the section structure itself.
6005 * som.c (make_unique_section): Delete unused declaration.
6006 (som_bfd_copy_private_bfd_data): New function.
6007 (som_object_setup): Allocate space for and save exec information
6008 that needs to be copied during objcopy/strip.
6009 (som_mkobject): Do not allocate space for a file header here.
6010 It is not used when only reading SOM objects.
6011 (som_prep_headers): Allocate space for and attach a file header
6012 to the output bfd. For executables, use the saved system_id
6013 value rather than trying to guess the right value. Do not abort
6014 wwhen setting file_hdr->entry* for executables.
6015 (som_begin_writing): For executables, set the exec_entry and
6017 (som_copy_private_backend_section_data): Always return a value.
6019 * libhppa.h (PA_PAGESIZE): Define.
6021 * som.c (SOM_ALIGN): Define.
6022 (som_begin_writing): If writing an executable, initialize all
6023 fields in the exec header to zero. Update fields in the exec
6024 header as sizes of loadable subspaces are computed. Carefully
6025 preserve alignments when building executables. Actually write the
6026 exec after all the fields are filled in.
6028 * Better long-filename handling. Reads SOM ABI compliant extended
6029 names, but doesn't quite write compliant extended names yet.
6030 * som.c (som_slurp_extended_name_table): Delete function. The
6031 generic code will handle things correctly.
6032 (som_slurp_armap): Seek to the beginning of the next member.
6033 (normalize): New function.
6034 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6035 name table into account when computing the file offsets in the
6036 SOM dictionary. Make sure to align to an even boundary.
6037 (som_write_armap): Initialize the checksum to zero.
6038 (ar_maxchars): Fix. Opps.
6040 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6042 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6043 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6045 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6047 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6048 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6049 * bfd-in2.h: Regenerated.
6051 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6052 this was also named trad_unix_bfd_copy_private_bfd_data.
6054 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6056 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6057 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6058 returns NULL, it is not an error. It's possible that some of
6059 these checks are not necessary (because the size can never be
6060 zero), but putting in the checks is the conservative thing to do
6061 in light of the fact that some of these malloc calls replaced
6062 unchecked alloca calls, in which a zero argument would work fine.
6064 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6066 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6067 duplicate definition.
6068 (osf_core_bfd_is_local_label): Define.
6070 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6071 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6072 failure indication, it merely means there are no relocs.
6074 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6075 after NAME, since SunOS /bin/cc can't handle it.
6077 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6079 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6080 From sukes@glue.umd.edu (Tasuki Hirata).
6082 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6084 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6085 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6086 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6088 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6090 * som.c (som_prep_for_fixups): Detect section symbols based
6091 on either the lack of private data or the symbol flags. Do not
6092 munge section symbol names anymore -- they no longer confuse GDB.
6093 (som_begin_writing): Leave space for an exec header if writing
6095 (som_slurp_symbol_table): Recognize both forms of section symbol
6096 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6097 section symbols to be the name of the section they represent.
6098 Debugging symbols begin with "L$0\001", not just "L$".
6100 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6102 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6104 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6105 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6106 and bfd_is_local_label.
6108 * targets.c: Add new entries to the bfd_target structure.
6110 * bfd.c (bfd_copy_private_bfd_data): New definition.

7228 undefined, look it up in the linker hash table.
7230 * aoutx.h (translate_symbol_table): The string index 0 has a

7255 The sparc (and possibly other?) NLM format requires a different
7256 way to write exports, so add a write_export field to the backend
7257 data (and set it to NULL for everything but the sparc).
