481 Treat a R_386_PLT32 reloc against a symbol for which we did not
482 create a PLT entry as a R_386_PC32 reloc.

503 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
504 seen, skip most of this function, and force the size of the
505 .rela.got section to zero. Strip empty reloc sections, and strip
506 an empty .plt section.
507 (elf32_sparc_relocate_section): For a GOT reloc against a global
508 symbol when no dynamic object was seen, initialize the contents of
509 the .got section. For a GOT reloc against a local symbol, only
510 create a R_SPARC_RELATIVE reloc when generating a shared object.
511 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
512 create a PLT entry as a R_SPARC_WDISP30 reloc.
513 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
514 dynamic entries and the PLT if we saw a dynamic object.

3898 * som.c (som_begin_writing): New approach at dealing with holes
3899 in executables left by the HP linker. Does not rely on subspace
3900 alignments as subspaces are *NOT* guaranteed to be properly
3901 aligned in an executable (can you believe that!).
3903 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3905 * som.c (som_get_section_contents): New function. Do not try

3951 required by expansions. Set s and unset h when converting a reloc
3952 from undefined to section. Change handling of PC relative relocs:
3953 if against a section, they are correct in the object file, if
3954 against an external symbol they are pcrel_offset.
3955 (mips_relax_section): New function.
3956 (mips_relax_pcrel16): New function.
3957 (ecoff_bfd_relax_section): Define.

3963 * aoutx.h (NAME(aout,find_nearest_line)): The caller expects
3964 functionname_ptr to be set to a symbol name, so prepend
3965 symbol_leading_char.

4041 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4042 reloc, used in embedded PIC code.
4043 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
4044 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

4050 link_order loop. Use _bfd_generic_link_add_symbols_collect for
4051 add_symbls entry point.
4053 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4054 counting relocs. Set SEC_RELOC flag for any section which has

4062 _bfd_generic_link_add_symbols but also collect constructors and
4063 destructors by name as collect2 does.

4082 extended name table.
4084 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4086 Support for link_order types which generate relocs in order to
4087 support -Ur in the linker.
4088 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4089 from call to _bfd_generic_link_add_one_symbol.
4090 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4091 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4092 instead of bitsize to add_to_set call back.
4093 (_bfd_generic_final_link): Account for link_order relocs when
4094 allocating space for relocations. Handle them in link_order loop.
4095 (_bfd_generic_reloc_link_order): New function.

4100 argument from declaration.
4101 (_bfd_generic_reloc_link_order): Declare.

4112 (ecoff_bfd_final_link): Account for link_order relocs when
4113 allocating space for relocations. Handle them in link_order loop.
4114 (ecoff_link_write_external): Set the storage class of a defined
4115 linker created symbol based on the section it is in. Correct
4116 bfd_link_hash_weak case to use .sc rather than .st.
4117 (ecoff_reloc_link_order): New function.
4118 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4120 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4125 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4126 bfd_zmalloc. Free a pointer, not a union.
4127 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4129 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4131 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4133 * som.c (bfd_section_from_som_symbol): Only to do the value
4134 comparison for function symbols within executables.
4136 * som.c (bfd_section_from_som_symbol): Renamed from
4137 som_section_from_subspace_index. Pass in a native SOM symbol.
4138 For executables, iterate through the sections to find out
4139 which contains the symbol's address rather than using the
4140 symbol_info field. (symbol_info has a different meaning for
4141 dynamicly linked executables.)
4143 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4146 * som.c (som_begin_writing): Fix braino (one call to align
4147 space/subspace data was done unconditionally rather than
4148 just for executables.)
4150 * som.c (som_begin_writing): Align text in all executables to
4151 make HPUX kernel happy. Fixes strip/objcopy for shared
4154 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4156 * som.c (som_begin_writing): Account for alignment needs of
4157 subspaces too when writing executables. Never request a negative
4158 bss size. Fixes some problems with demand paged executables,
4159 still having problems with pure executables and shared executables.
4161 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4163 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4164 bfd_zalloc for rawptr, because later on we may call free, not
4167 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4168 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4169 * cisco-core.c: New file.
4170 * Makefile.in: Change accordingly.
4171 * configure.in: Recognize cisco_core_vec.
4172 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4173 * targets.c: Add cisco_core_vec.
4174 * bfd-in2.h: Rebuilt.
4176 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4178 * som.h (som_copyable_section_data_struct): New structure
4179 containing all the private section information which needs
4180 to be copied from input section to output section during
4182 (som_section_data_struct): Remove several fields now in
4183 som_copyable_section_data_struct. Make the space and
4184 subspace dictionaries be pointers (to save space when
4185 only reading objects).
4187 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4188 some references changed. Allocate a copyable data stucture if
4189 none exists. Store info into the copyable data structure.
4190 (bfd_som_set_subsection_attributes): Likewise.
4191 (som_is_space, som_is_subspace, som_is_container): New functions.
4192 Use these instead of directly accessing private data.
4193 (som_prep_headers): Allocate space and subspace headers here.
4194 Fill in some fields in the space/subspace headers from the
4196 (som_bfd_copy_private_section_data): Only copy the stuff
4197 that we really need to make objcopy and strip work. Allocate
4198 the copy_data structure for the output bfd before copying.
4200 * som.h (struct som_exec_data): New structure to hold exec
4201 info that must be preserved when running objcopy/strip.
4202 (struct somdata): Add new "exec_data" field and accessor
4203 macro. Add some comments on how the various fields are used.
4204 (som_section_data_struct): Make is_space and is_subspace bitfields.
4205 Delete unused subspace_index. All references now use the
4206 target_index field within the section structure itself.
4208 * som.c (make_unique_section): Delete unused declaration.
4209 (som_bfd_copy_private_bfd_data): New function.
4210 (som_object_setup): Allocate space for and save exec information
4211 that needs to be copied during objcopy/strip.
4212 (som_mkobject): Do not allocate space for a file header here.
4213 It is not used when only reading SOM objects.
4214 (som_prep_headers): Allocate space for and attach a file header
4215 to the output bfd. For executables, use the saved system_id
4216 value rather than trying to guess the right value. Do not abort
4217 wwhen setting file_hdr->entry* for executables.
4218 (som_begin_writing): For executables, set the exec_entry and
4220 (som_copy_private_backend_section_data): Always return a value.
4222 * libhppa.h (PA_PAGESIZE): Define.
4224 * som.c (SOM_ALIGN): Define.
4225 (som_begin_writing): If writing an executable, initialize all
4226 fields in the exec header to zero. Update fields in the exec
4227 header as sizes of loadable subspaces are computed. Carefully
4228 preserve alignments when building executables. Actually write the
4229 exec after all the fields are filled in.
4231 * Better long-filename handling. Reads SOM ABI compliant extended
4232 names, but doesn't quite write compliant extended names yet.
4233 * som.c (som_slurp_extended_name_table): Delete function. The
4234 generic code will handle things correctly.
4235 (som_slurp_armap): Seek to the beginning of the next member.
4236 (normalize): New function.
4237 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4238 name table into account when computing the file offsets in the
4239 SOM dictionary. Make sure to align to an even boundary.
4240 (som_write_armap): Initialize the checksum to zero.
4241 (ar_maxchars): Fix. Opps.
4243 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4245 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4246 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4248 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4250 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4251 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4252 * bfd-in2.h: Regenerated.
4254 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4255 this was also named trad_unix_bfd_copy_private_bfd_data.
4257 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4259 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4260 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4261 returns NULL, it is not an error. It's possible that some of
4262 these checks are not necessary (because the size can never be
4263 zero), but putting in the checks is the conservative thing to do
4264 in light of the fact that some of these malloc calls replaced
4265 unchecked alloca calls, in which a zero argument would work fine.
4267 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4269 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4270 duplicate definition.
4271 (osf_core_bfd_is_local_label): Define.
4273 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4274 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4275 failure indication, it merely means there are no relocs.
4277 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4278 after NAME, since SunOS /bin/cc can't handle it.
4280 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4282 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4283 From sukes@glue.umd.edu (Tasuki Hirata).
4285 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4287 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4288 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4289 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4291 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4293 * som.c (som_prep_for_fixups): Detect section symbols based
4294 on either the lack of private data or the symbol flags. Do not
4295 munge section symbol names anymore -- they no longer confuse GDB.
4296 (som_begin_writing): Leave space for an exec header if writing
4298 (som_slurp_symbol_table): Recognize both forms of section symbol
4299 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4300 section symbols to be the name of the section they represent.
4301 Debugging symbols begin with "L$0\001", not just "L$".
4303 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4305 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4307 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table

4400 cruft (like the #pragma alloca for AIX).
4401 In addition to that problem, the C alloca calls xmalloc, which

5431 undefined, look it up in the linker hash table.
5433 * aoutx.h (translate_symbol_table): The string index 0 has a

5458 The sparc (and possibly other?) NLM format requires a different
5459 way to write exports, so add a write_export field to the backend
5460 data (and set it to NULL for everything but the sparc).
