480 create a PLT entry as a R_SPARC_WDISP30 reloc.
481 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
482 dynamic entries and the PLT if we saw a dynamic object.

3881 failing bfd_read, bfd_write, or bfd_seek. In a few places
3882 (like som_object_p) override the error status set by bfd_read.

3919 required by expansions. Set s and unset h when converting a reloc
3920 from undefined to section. Change handling of PC relative relocs:
3921 if against a section, they are correct in the object file, if
3922 against an external symbol they are pcrel_offset.
3923 (mips_relax_section): New function.
3924 (mips_relax_pcrel16): New function.
3925 (ecoff_bfd_relax_section): Define.

4010 reloc, used in embedded PIC code.
4011 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
4012 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

4019 add_symbls entry point.
4021 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4022 counting relocs. Set SEC_RELOC flag for any section which has

4050 extended name table.
4052 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4054 Support for link_order types which generate relocs in order to
4055 support -Ur in the linker.
4056 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4057 from call to _bfd_generic_link_add_one_symbol.
4058 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4059 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4060 instead of bitsize to add_to_set call back.
4061 (_bfd_generic_final_link): Account for link_order relocs when
4062 allocating space for relocations. Handle them in link_order loop.
4063 (_bfd_generic_reloc_link_order): New function.

4080 (ecoff_bfd_final_link): Account for link_order relocs when
4081 allocating space for relocations. Handle them in link_order loop.
4082 (ecoff_link_write_external): Set the storage class of a defined
4083 linker created symbol based on the section it is in. Correct
4084 bfd_link_hash_weak case to use .sc rather than .st.
4085 (ecoff_reloc_link_order): New function.
4086 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4088 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4093 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4094 bfd_zmalloc. Free a pointer, not a union.
4095 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4097 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4099 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4101 * som.c (bfd_section_from_som_symbol): Only to do the value
4102 comparison for function symbols within executables.
4104 * som.c (bfd_section_from_som_symbol): Renamed from
4105 som_section_from_subspace_index. Pass in a native SOM symbol.
4106 For executables, iterate through the sections to find out
4107 which contains the symbol's address rather than using the
4108 symbol_info field. (symbol_info has a different meaning for
4109 dynamicly linked executables.)
4111 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4114 * som.c (som_begin_writing): Fix braino (one call to align
4115 space/subspace data was done unconditionally rather than
4116 just for executables.)
4118 * som.c (som_begin_writing): Align text in all executables to
4119 make HPUX kernel happy. Fixes strip/objcopy for shared
4122 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4124 * som.c (som_begin_writing): Account for alignment needs of
4125 subspaces too when writing executables. Never request a negative
4126 bss size. Fixes some problems with demand paged executables,
4127 still having problems with pure executables and shared executables.
4129 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4131 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4132 bfd_zalloc for rawptr, because later on we may call free, not
4135 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4136 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4137 * cisco-core.c: New file.
4138 * Makefile.in: Change accordingly.
4139 * configure.in: Recognize cisco_core_vec.
4140 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4141 * targets.c: Add cisco_core_vec.
4142 * bfd-in2.h: Rebuilt.
4144 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4146 * som.h (som_copyable_section_data_struct): New structure
4147 containing all the private section information which needs
4148 to be copied from input section to output section during
4150 (som_section_data_struct): Remove several fields now in
4151 som_copyable_section_data_struct. Make the space and
4152 subspace dictionaries be pointers (to save space when
4153 only reading objects).
4155 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4156 some references changed. Allocate a copyable data stucture if
4157 none exists. Store info into the copyable data structure.
4158 (bfd_som_set_subsection_attributes): Likewise.
4159 (som_is_space, som_is_subspace, som_is_container): New functions.
4160 Use these instead of directly accessing private data.
4161 (som_prep_headers): Allocate space and subspace headers here.
4162 Fill in some fields in the space/subspace headers from the
4164 (som_bfd_copy_private_section_data): Only copy the stuff
4165 that we really need to make objcopy and strip work. Allocate
4166 the copy_data structure for the output bfd before copying.
4168 * som.h (struct som_exec_data): New structure to hold exec
4169 info that must be preserved when running objcopy/strip.
4170 (struct somdata): Add new "exec_data" field and accessor
4171 macro. Add some comments on how the various fields are used.
4172 (som_section_data_struct): Make is_space and is_subspace bitfields.
4173 Delete unused subspace_index. All references now use the
4174 target_index field within the section structure itself.
4176 * som.c (make_unique_section): Delete unused declaration.
4177 (som_bfd_copy_private_bfd_data): New function.
4178 (som_object_setup): Allocate space for and save exec information
4179 that needs to be copied during objcopy/strip.
4180 (som_mkobject): Do not allocate space for a file header here.
4181 It is not used when only reading SOM objects.
4182 (som_prep_headers): Allocate space for and attach a file header
4183 to the output bfd. For executables, use the saved system_id
4184 value rather than trying to guess the right value. Do not abort
4185 wwhen setting file_hdr->entry* for executables.
4186 (som_begin_writing): For executables, set the exec_entry and
4188 (som_copy_private_backend_section_data): Always return a value.
4190 * libhppa.h (PA_PAGESIZE): Define.
4192 * som.c (SOM_ALIGN): Define.
4193 (som_begin_writing): If writing an executable, initialize all
4194 fields in the exec header to zero. Update fields in the exec
4195 header as sizes of loadable subspaces are computed. Carefully
4196 preserve alignments when building executables. Actually write the
4197 exec after all the fields are filled in.
4199 * Better long-filename handling. Reads SOM ABI compliant extended
4200 names, but doesn't quite write compliant extended names yet.
4201 * som.c (som_slurp_extended_name_table): Delete function. The
4202 generic code will handle things correctly.
4203 (som_slurp_armap): Seek to the beginning of the next member.
4204 (normalize): New function.
4205 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4206 name table into account when computing the file offsets in the
4207 SOM dictionary. Make sure to align to an even boundary.
4208 (som_write_armap): Initialize the checksum to zero.
4209 (ar_maxchars): Fix. Opps.
4211 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4213 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4214 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4216 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4218 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4219 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4220 * bfd-in2.h: Regenerated.
4222 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4223 this was also named trad_unix_bfd_copy_private_bfd_data.
4225 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4227 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4228 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4229 returns NULL, it is not an error. It's possible that some of
4230 these checks are not necessary (because the size can never be
4231 zero), but putting in the checks is the conservative thing to do
4232 in light of the fact that some of these malloc calls replaced
4233 unchecked alloca calls, in which a zero argument would work fine.
4235 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4237 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4238 duplicate definition.
4239 (osf_core_bfd_is_local_label): Define.
4241 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4242 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4243 failure indication, it merely means there are no relocs.
4245 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4246 after NAME, since SunOS /bin/cc can't handle it.
4248 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4250 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4251 From sukes@glue.umd.edu (Tasuki Hirata).
4253 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4255 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4256 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4257 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4259 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4261 * som.c (som_prep_for_fixups): Detect section symbols based
4262 on either the lack of private data or the symbol flags. Do not
4263 munge section symbol names anymore -- they no longer confuse GDB.
4264 (som_begin_writing): Leave space for an exec header if writing
4266 (som_slurp_symbol_table): Recognize both forms of section symbol
4267 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4268 section symbols to be the name of the section they represent.
4269 Debugging symbols begin with "L$0\001", not just "L$".
4271 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4273 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4275 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4276 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4277 and bfd_is_local_label.
4279 * targets.c: Add new entries to the bfd_target structure.
4281 * bfd.c (bfd_copy_private_bfd_data): New definition.
4283 * section.c (bfd_copy_private_section_data): New definition.

4292 the target vector which all point to bfd_false.
4294 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4295 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4296 Default new vectors for copying private backend data to bfd_true.
4297 Default new vector for determining if a symbol is a local label
4298 to bfd_generic_is_local_label.
4300 * som.c (som_bfd_copy_private_section_data): New function.
4301 (som_bfd_is_local_label): New function.
4302 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4304 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4306 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

4368 cruft (like the #pragma alloca for AIX).
4369 In addition to that problem, the C alloca calls xmalloc, which

5399 undefined, look it up in the linker hash table.
5401 * aoutx.h (translate_symbol_table): The string index 0 has a

5426 The sparc (and possibly other?) NLM format requires a different
5427 way to write exports, so add a write_export field to the backend
5428 data (and set it to NULL for everything but the sparc).
