4815 from undefined to section. Change handling of PC relative relocs:
4816 if against a section, they are correct in the object file, if
4817 against an external symbol they are pcrel_offset.
4818 (mips_relax_section): New function.
4819 (mips_relax_pcrel16): New function.

4905 reloc, used in embedded PIC code.
4906 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

4945 extended name table.
4947 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4949 Support for link_order types which generate relocs in order to
4950 support -Ur in the linker.
4951 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4952 from call to _bfd_generic_link_add_one_symbol.
4953 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4954 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4955 instead of bitsize to add_to_set call back.
4956 (_bfd_generic_final_link): Account for link_order relocs when
4957 allocating space for relocations. Handle them in link_order loop.
4958 (_bfd_generic_reloc_link_order): New function.

4976 allocating space for relocations. Handle them in link_order loop.
4977 (ecoff_link_write_external): Set the storage class of a defined
4978 linker created symbol based on the section it is in. Correct
4979 bfd_link_hash_weak case to use .sc rather than .st.
4980 (ecoff_reloc_link_order): New function.
4981 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4983 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4989 bfd_zmalloc. Free a pointer, not a union.
4990 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4992 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4994 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4996 * som.c (bfd_section_from_som_symbol): Only to do the value
4997 comparison for function symbols within executables.
4999 * som.c (bfd_section_from_som_symbol): Renamed from
5000 som_section_from_subspace_index. Pass in a native SOM symbol.
5001 For executables, iterate through the sections to find out
5002 which contains the symbol's address rather than using the
5003 symbol_info field. (symbol_info has a different meaning for
5004 dynamicly linked executables.)
5006 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5009 * som.c (som_begin_writing): Fix braino (one call to align
5010 space/subspace data was done unconditionally rather than
5011 just for executables.)
5013 * som.c (som_begin_writing): Align text in all executables to
5014 make HPUX kernel happy. Fixes strip/objcopy for shared
5017 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5019 * som.c (som_begin_writing): Account for alignment needs of
5020 subspaces too when writing executables. Never request a negative
5021 bss size. Fixes some problems with demand paged executables,
5022 still having problems with pure executables and shared executables.
5024 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5026 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5027 bfd_zalloc for rawptr, because later on we may call free, not
5030 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5031 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5032 * cisco-core.c: New file.

5039 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5041 * som.h (som_copyable_section_data_struct): New structure
5042 containing all the private section information which needs
5043 to be copied from input section to output section during
5045 (som_section_data_struct): Remove several fields now in
5046 som_copyable_section_data_struct. Make the space and
5047 subspace dictionaries be pointers (to save space when
5048 only reading objects).
5050 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5051 some references changed. Allocate a copyable data stucture if
5052 none exists. Store info into the copyable data structure.
5053 (bfd_som_set_subsection_attributes): Likewise.
5054 (som_is_space, som_is_subspace, som_is_container): New functions.
5055 Use these instead of directly accessing private data.
5056 (som_prep_headers): Allocate space and subspace headers here.
5057 Fill in some fields in the space/subspace headers from the
5059 (som_bfd_copy_private_section_data): Only copy the stuff
5060 that we really need to make objcopy and strip work. Allocate
5061 the copy_data structure for the output bfd before copying.
5063 * som.h (struct som_exec_data): New structure to hold exec
5064 info that must be preserved when running objcopy/strip.
5065 (struct somdata): Add new "exec_data" field and accessor
5066 macro. Add some comments on how the various fields are used.
5067 (som_section_data_struct): Make is_space and is_subspace bitfields.
5068 Delete unused subspace_index. All references now use the
5069 target_index field within the section structure itself.
5071 * som.c (make_unique_section): Delete unused declaration.
5072 (som_bfd_copy_private_bfd_data): New function.
5073 (som_object_setup): Allocate space for and save exec information
5074 that needs to be copied during objcopy/strip.
5075 (som_mkobject): Do not allocate space for a file header here.
5076 It is not used when only reading SOM objects.
5077 (som_prep_headers): Allocate space for and attach a file header
5078 to the output bfd. For executables, use the saved system_id
5079 value rather than trying to guess the right value. Do not abort
5080 wwhen setting file_hdr->entry* for executables.
5081 (som_begin_writing): For executables, set the exec_entry and
5083 (som_copy_private_backend_section_data): Always return a value.
5085 * libhppa.h (PA_PAGESIZE): Define.
5087 * som.c (SOM_ALIGN): Define.
5088 (som_begin_writing): If writing an executable, initialize all
5089 fields in the exec header to zero. Update fields in the exec
5090 header as sizes of loadable subspaces are computed. Carefully
5091 preserve alignments when building executables. Actually write the
5092 exec after all the fields are filled in.
5094 * Better long-filename handling. Reads SOM ABI compliant extended
5095 names, but doesn't quite write compliant extended names yet.
5096 * som.c (som_slurp_extended_name_table): Delete function. The
5097 generic code will handle things correctly.
5098 (som_slurp_armap): Seek to the beginning of the next member.
5099 (normalize): New function.
5100 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5101 name table into account when computing the file offsets in the
5102 SOM dictionary. Make sure to align to an even boundary.
5103 (som_write_armap): Initialize the checksum to zero.
5104 (ar_maxchars): Fix. Opps.
5106 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5108 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5109 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5111 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5113 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5114 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5115 * bfd-in2.h: Regenerated.
5117 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5118 this was also named trad_unix_bfd_copy_private_bfd_data.
5120 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5122 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5123 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5124 returns NULL, it is not an error. It's possible that some of
5125 these checks are not necessary (because the size can never be
5126 zero), but putting in the checks is the conservative thing to do
5127 in light of the fact that some of these malloc calls replaced
5128 unchecked alloca calls, in which a zero argument would work fine.
5130 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5132 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5133 duplicate definition.
5134 (osf_core_bfd_is_local_label): Define.
5136 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5137 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5138 failure indication, it merely means there are no relocs.
5140 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5141 after NAME, since SunOS /bin/cc can't handle it.
5143 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5145 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5146 From sukes@glue.umd.edu (Tasuki Hirata).
5148 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5150 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5151 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5152 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5154 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5156 * som.c (som_prep_for_fixups): Detect section symbols based
5157 on either the lack of private data or the symbol flags. Do not
5158 munge section symbol names anymore -- they no longer confuse GDB.
5159 (som_begin_writing): Leave space for an exec header if writing
5161 (som_slurp_symbol_table): Recognize both forms of section symbol
5162 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5163 section symbols to be the name of the section they represent.
5164 Debugging symbols begin with "L$0\001", not just "L$".
5166 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5168 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5170 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5171 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5172 and bfd_is_local_label.
5174 * targets.c: Add new entries to the bfd_target structure.

5187 the target vector which all point to bfd_false.
5189 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5190 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5191 Default new vectors for copying private backend data to bfd_true.
5192 Default new vector for determining if a symbol is a local label
5193 to bfd_generic_is_local_label.
5195 * som.c (som_bfd_copy_private_section_data): New function.
5196 (som_bfd_is_local_label): New function.
5197 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5199 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5201 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5203 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5205 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5208 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5209 Indent some of them to GNU standards.
5211 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5212 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

5227 for spaces and subspaces.
5229 * som.c (som_bfd_count_ar_symbols): Fix typo.

5263 cruft (like the #pragma alloca for AIX).
5264 In addition to that problem, the C alloca calls xmalloc, which

6321 The sparc (and possibly other?) NLM format requires a different
6322 way to write exports, so add a write_export field to the backend
6323 data (and set it to NULL for everything but the sparc).
