512 (elf32_sparc_relocate_section): For a GOT reloc against a global
513 symbol when no dynamic object was seen, initialize the contents of
514 the .got section. For a GOT reloc against a local symbol, only
515 create a R_SPARC_RELATIVE reloc when generating a shared object.

517 create a PLT entry as a R_SPARC_WDISP30 reloc.
518 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
519 dynamic entries and the PLT if we saw a dynamic object.

3903 * som.c (som_begin_writing): New approach at dealing with holes
3904 in executables left by the HP linker. Does not rely on subspace
3905 alignments as subspaces are *NOT* guaranteed to be properly

3956 required by expansions. Set s and unset h when converting a reloc
3957 from undefined to section. Change handling of PC relative relocs:
3958 if against a section, they are correct in the object file, if
3959 against an external symbol they are pcrel_offset.
3960 (mips_relax_section): New function.
3961 (mips_relax_pcrel16): New function.
3962 (ecoff_bfd_relax_section): Define.

4046 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4047 reloc, used in embedded PIC code.
4048 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
4049 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

4055 link_order loop. Use _bfd_generic_link_add_symbols_collect for
4056 add_symbls entry point.
4058 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4059 counting relocs. Set SEC_RELOC flag for any section which has

4067 _bfd_generic_link_add_symbols but also collect constructors and
4068 destructors by name as collect2 does.

4087 extended name table.
4089 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4091 Support for link_order types which generate relocs in order to
4092 support -Ur in the linker.
4093 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4094 from call to _bfd_generic_link_add_one_symbol.
4095 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4096 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4097 instead of bitsize to add_to_set call back.
4098 (_bfd_generic_final_link): Account for link_order relocs when
4099 allocating space for relocations. Handle them in link_order loop.
4100 (_bfd_generic_reloc_link_order): New function.

4117 (ecoff_bfd_final_link): Account for link_order relocs when
4118 allocating space for relocations. Handle them in link_order loop.
4119 (ecoff_link_write_external): Set the storage class of a defined
4120 linker created symbol based on the section it is in. Correct
4121 bfd_link_hash_weak case to use .sc rather than .st.
4122 (ecoff_reloc_link_order): New function.
4123 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4125 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4131 bfd_zmalloc. Free a pointer, not a union.
4132 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4134 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4136 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4138 * som.c (bfd_section_from_som_symbol): Only to do the value
4139 comparison for function symbols within executables.
4141 * som.c (bfd_section_from_som_symbol): Renamed from
4142 som_section_from_subspace_index. Pass in a native SOM symbol.
4143 For executables, iterate through the sections to find out
4144 which contains the symbol's address rather than using the
4145 symbol_info field. (symbol_info has a different meaning for
4146 dynamicly linked executables.)
4148 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4151 * som.c (som_begin_writing): Fix braino (one call to align
4152 space/subspace data was done unconditionally rather than
4153 just for executables.)
4155 * som.c (som_begin_writing): Align text in all executables to
4156 make HPUX kernel happy. Fixes strip/objcopy for shared
4159 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4161 * som.c (som_begin_writing): Account for alignment needs of
4162 subspaces too when writing executables. Never request a negative
4163 bss size. Fixes some problems with demand paged executables,
4164 still having problems with pure executables and shared executables.
4166 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4168 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4169 bfd_zalloc for rawptr, because later on we may call free, not
4172 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4173 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4174 * cisco-core.c: New file.
4175 * Makefile.in: Change accordingly.
4176 * configure.in: Recognize cisco_core_vec.
4177 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4178 * targets.c: Add cisco_core_vec.
4179 * bfd-in2.h: Rebuilt.
4181 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4183 * som.h (som_copyable_section_data_struct): New structure
4184 containing all the private section information which needs
4185 to be copied from input section to output section during
4187 (som_section_data_struct): Remove several fields now in
4188 som_copyable_section_data_struct. Make the space and
4189 subspace dictionaries be pointers (to save space when
4190 only reading objects).
4192 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4193 some references changed. Allocate a copyable data stucture if
4194 none exists. Store info into the copyable data structure.
4195 (bfd_som_set_subsection_attributes): Likewise.
4196 (som_is_space, som_is_subspace, som_is_container): New functions.
4197 Use these instead of directly accessing private data.
4198 (som_prep_headers): Allocate space and subspace headers here.
4199 Fill in some fields in the space/subspace headers from the
4201 (som_bfd_copy_private_section_data): Only copy the stuff
4202 that we really need to make objcopy and strip work. Allocate
4203 the copy_data structure for the output bfd before copying.
4205 * som.h (struct som_exec_data): New structure to hold exec
4206 info that must be preserved when running objcopy/strip.
4207 (struct somdata): Add new "exec_data" field and accessor
4208 macro. Add some comments on how the various fields are used.
4209 (som_section_data_struct): Make is_space and is_subspace bitfields.
4210 Delete unused subspace_index. All references now use the
4211 target_index field within the section structure itself.
4213 * som.c (make_unique_section): Delete unused declaration.
4214 (som_bfd_copy_private_bfd_data): New function.
4215 (som_object_setup): Allocate space for and save exec information
4216 that needs to be copied during objcopy/strip.
4217 (som_mkobject): Do not allocate space for a file header here.
4218 It is not used when only reading SOM objects.
4219 (som_prep_headers): Allocate space for and attach a file header
4220 to the output bfd. For executables, use the saved system_id
4221 value rather than trying to guess the right value. Do not abort
4222 wwhen setting file_hdr->entry* for executables.
4223 (som_begin_writing): For executables, set the exec_entry and
4225 (som_copy_private_backend_section_data): Always return a value.
4227 * libhppa.h (PA_PAGESIZE): Define.
4229 * som.c (SOM_ALIGN): Define.
4230 (som_begin_writing): If writing an executable, initialize all
4231 fields in the exec header to zero. Update fields in the exec
4232 header as sizes of loadable subspaces are computed. Carefully
4233 preserve alignments when building executables. Actually write the
4234 exec after all the fields are filled in.
4236 * Better long-filename handling. Reads SOM ABI compliant extended
4237 names, but doesn't quite write compliant extended names yet.
4238 * som.c (som_slurp_extended_name_table): Delete function. The
4239 generic code will handle things correctly.
4240 (som_slurp_armap): Seek to the beginning of the next member.
4241 (normalize): New function.
4242 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4243 name table into account when computing the file offsets in the
4244 SOM dictionary. Make sure to align to an even boundary.
4245 (som_write_armap): Initialize the checksum to zero.
4246 (ar_maxchars): Fix. Opps.
4248 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4250 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4251 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4253 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4255 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4256 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4257 * bfd-in2.h: Regenerated.
4259 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4260 this was also named trad_unix_bfd_copy_private_bfd_data.
4262 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4264 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4265 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4266 returns NULL, it is not an error. It's possible that some of
4267 these checks are not necessary (because the size can never be
4268 zero), but putting in the checks is the conservative thing to do
4269 in light of the fact that some of these malloc calls replaced
4270 unchecked alloca calls, in which a zero argument would work fine.
4272 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4274 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4275 duplicate definition.
4276 (osf_core_bfd_is_local_label): Define.
4278 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4279 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4280 failure indication, it merely means there are no relocs.
4282 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4283 after NAME, since SunOS /bin/cc can't handle it.
4285 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4287 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4288 From sukes@glue.umd.edu (Tasuki Hirata).
4290 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4292 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4293 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4294 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4296 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4298 * som.c (som_prep_for_fixups): Detect section symbols based
4299 on either the lack of private data or the symbol flags. Do not
4300 munge section symbol names anymore -- they no longer confuse GDB.
4301 (som_begin_writing): Leave space for an exec header if writing
4303 (som_slurp_symbol_table): Recognize both forms of section symbol
4304 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4305 section symbols to be the name of the section they represent.
4306 Debugging symbols begin with "L$0\001", not just "L$".

5325 bfd_som_set_subsection_attributes): Change parameters from char
5326 to int. Following a prototype with an old-style function definition

5436 undefined, look it up in the linker hash table.
5438 * aoutx.h (translate_symbol_table): The string index 0 has a

5463 The sparc (and possibly other?) NLM format requires a different
5464 way to write exports, so add a write_export field to the backend
5465 data (and set it to NULL for everything but the sparc).
