1454 an empty .plt section.
1455 (elf32_sparc_relocate_section): For a GOT reloc against a global
1456 symbol when no dynamic object was seen, initialize the contents of
1457 the .got section. For a GOT reloc against a local symbol, only
1458 create a R_SPARC_RELATIVE reloc when generating a shared object.
1459 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1460 create a PLT entry as a R_SPARC_WDISP30 reloc.

5035 support -Ur in the linker.
5036 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5037 from call to _bfd_generic_link_add_one_symbol.
5038 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5039 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5040 instead of bitsize to add_to_set call back.
5041 (_bfd_generic_final_link): Account for link_order relocs when
5042 allocating space for relocations. Handle them in link_order loop.

5086 For executables, iterate through the sections to find out
5087 which contains the symbol's address rather than using the
5088 symbol_info field. (symbol_info has a different meaning for
5089 dynamicly linked executables.)
5091 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5094 * som.c (som_begin_writing): Fix braino (one call to align
5095 space/subspace data was done unconditionally rather than
5096 just for executables.)
5098 * som.c (som_begin_writing): Align text in all executables to
5099 make HPUX kernel happy. Fixes strip/objcopy for shared
5102 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5104 * som.c (som_begin_writing): Account for alignment needs of
5105 subspaces too when writing executables. Never request a negative
5106 bss size. Fixes some problems with demand paged executables,
5107 still having problems with pure executables and shared executables.
5109 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5111 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

5126 * som.h (som_copyable_section_data_struct): New structure
5127 containing all the private section information which needs
5128 to be copied from input section to output section during
5130 (som_section_data_struct): Remove several fields now in
5131 som_copyable_section_data_struct. Make the space and
5132 subspace dictionaries be pointers (to save space when
5133 only reading objects).
5135 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5136 some references changed. Allocate a copyable data stucture if
5137 none exists. Store info into the copyable data structure.
5138 (bfd_som_set_subsection_attributes): Likewise.
5139 (som_is_space, som_is_subspace, som_is_container): New functions.
5140 Use these instead of directly accessing private data.
5141 (som_prep_headers): Allocate space and subspace headers here.
5142 Fill in some fields in the space/subspace headers from the
5144 (som_bfd_copy_private_section_data): Only copy the stuff
5145 that we really need to make objcopy and strip work. Allocate
5146 the copy_data structure for the output bfd before copying.
5148 * som.h (struct som_exec_data): New structure to hold exec
5149 info that must be preserved when running objcopy/strip.
5150 (struct somdata): Add new "exec_data" field and accessor
5151 macro. Add some comments on how the various fields are used.
5152 (som_section_data_struct): Make is_space and is_subspace bitfields.
5153 Delete unused subspace_index. All references now use the
5154 target_index field within the section structure itself.
5156 * som.c (make_unique_section): Delete unused declaration.
5157 (som_bfd_copy_private_bfd_data): New function.
5158 (som_object_setup): Allocate space for and save exec information
5159 that needs to be copied during objcopy/strip.
5160 (som_mkobject): Do not allocate space for a file header here.
5161 It is not used when only reading SOM objects.
5162 (som_prep_headers): Allocate space for and attach a file header
5163 to the output bfd. For executables, use the saved system_id
5164 value rather than trying to guess the right value. Do not abort
5165 wwhen setting file_hdr->entry* for executables.
5166 (som_begin_writing): For executables, set the exec_entry and
5168 (som_copy_private_backend_section_data): Always return a value.
5170 * libhppa.h (PA_PAGESIZE): Define.
5172 * som.c (SOM_ALIGN): Define.
5173 (som_begin_writing): If writing an executable, initialize all
5174 fields in the exec header to zero. Update fields in the exec
5175 header as sizes of loadable subspaces are computed. Carefully
5176 preserve alignments when building executables. Actually write the
5177 exec after all the fields are filled in.
5179 * Better long-filename handling. Reads SOM ABI compliant extended
5180 names, but doesn't quite write compliant extended names yet.
5181 * som.c (som_slurp_extended_name_table): Delete function. The
5182 generic code will handle things correctly.
5183 (som_slurp_armap): Seek to the beginning of the next member.
5184 (normalize): New function.
5185 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5186 name table into account when computing the file offsets in the
5187 SOM dictionary. Make sure to align to an even boundary.
5188 (som_write_armap): Initialize the checksum to zero.
5189 (ar_maxchars): Fix. Opps.
5191 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5193 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5194 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5196 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

5199 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5200 * bfd-in2.h: Regenerated.
5202 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5203 this was also named trad_unix_bfd_copy_private_bfd_data.
5205 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5207 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5208 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5209 returns NULL, it is not an error. It's possible that some of
5210 these checks are not necessary (because the size can never be
5211 zero), but putting in the checks is the conservative thing to do
5212 in light of the fact that some of these malloc calls replaced
5213 unchecked alloca calls, in which a zero argument would work fine.
5215 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5217 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove

5222 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5223 failure indication, it merely means there are no relocs.
5225 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5226 after NAME, since SunOS /bin/cc can't handle it.
5228 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5230 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

5235 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5236 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5237 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5239 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5241 * som.c (som_prep_for_fixups): Detect section symbols based
5242 on either the lack of private data or the symbol flags. Do not
5243 munge section symbol names anymore -- they no longer confuse GDB.

5246 (som_slurp_symbol_table): Recognize both forms of section symbol
5247 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5248 section symbols to be the name of the section they represent.
5249 Debugging symbols begin with "L$0\001", not just "L$".

5302 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5304 * som.c (som_prep_for_fixups): A relocation involving the section
5305 symbol for the *ABS* section is really a relocation involving
5307 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5308 undefined symbols. Correctly distinguish between debugger symbols
5309 and section symbols.
5311 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5312 for spaces and subspaces.
5314 * som.c (som_bfd_count_ar_symbols): Fix typo.
5316 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5317 HAS_RELOC based on the object's magic number.
5318 (make_unique_section): Delete function. BFD and its users are
5319 prepared to handle multiple sections with the same name.
5320 (setup_sections): Allocate space on the BFD's obstack to hold
5321 section names. Use bfd_make_setion_anyway rather than the

5345 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5347 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5348 cruft (like the #pragma alloca for AIX).
5349 In addition to that problem, the C alloca calls xmalloc, which
5350 means checking for being out of memory can't work right. The
5351 following changes remove all uses of alloca from BFD.
5352 * hosts/solaris2.h: Remove alloca cruft.
5353 * som.c: Replace alloca with a fixed size auto array.

5394 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5395 include it in elf32-hppa.h.
5397 * som.c (log2): Return -1 on error rather than aborting.
5398 (setup_sections): Bubble up an error from log2.
5400 * Changes to make HP C compiler happy in both traditional
5402 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

5405 unsigned char to avoid GNU-C extensions.
5406 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5407 or failure rather than aborting on failure.
5409 * som.h (bfd_som_set_section_attributes): Fix prototype to match

5477 linker stubs into a single function (so they can easily share a
5478 ton of common code).

5526 COMPLEX relocation support (it's never used anyway).
5527 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

5686 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5688 * section.c (bfd_get_section_contents): Since this function reads
5689 unrelocated contents, the section's raw size is always the one to
5690 use for bounds checking.

5693 link_order size field against cooked size, not raw size, of input
5696 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
5698 (aligncode): When shrinking, the addend should be set to the
5699 current offset in the section plus the number of bytes of padding
5700 that will actually be retained.
5701 (b_out_relax_section): If a section contains no relocations, don't
5702 bother processing them.
5703 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5706 (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
5707 that reloc->addend falls between the current source offset and the
5708 raw size of the input section.
5710 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
5711 bout. Default with no version number is still bout. Support

6128 Fri Feb 4 23:55:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6130 Add basic support for writing RS/6000 XCOFF files.
6131 * coff-rs6000.c (dummy_reloc): Removed.
6132 (rs6000coff_howto_table): Defined XCOFF relocs.

6141 fields to bitfields. Added fields fix_value and fix_scnlen.
6142 (sec_to_styp_flags): If STYP_DEBUG is defined, use it rather than
6143 STYP_INFO for the type of a section named .debug.
6144 (coff_add_missing_symbols): Don't define if RS6000COFF_C.
6145 (coff_write_object_contents): If RS6000COFF_C, don't call

6148 entry has type STY_LD change the x_scnlen into a pointer to a
6149 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
6150 value into a pointer to a symbol and set fix_value.
6151 * libcoff.h: Rebuilt.

6156 (coff_fix_symbol_name): If bfd_coff_symname_in_debug returns true,
6157 write the symbol name into the .debug section; assume that the

6159 (coff_write_symbols): Initialize debug_string_size to 0. If
6160 bfd_coff_symname_in_debug returns true, don't put symbol name in
6161 usual string table. After writing out all symbols, if
6162 debug_string_size is not 0, check that it matches the size of the

6165 fields. If the string offset is 0, always use an empty string as
6167 (coff_make_empty_symbol): Zero out the symbol structure.

6186 symbol has a value in the ECOFF symbol but not in the BFD symbol,
6187 keep the value in the ECOFF symbol. This helps gas.
6189 * linker.c (_bfd_generic_link_output_symbols,
6190 _bfd_generic_link_write_global_symbol): Don't require that all
6191 references to a common symbol be themselves common symbols.

6231 new arguments to swap_aux functions.
6233 Sun Jan 30 15:14:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6235 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
6236 (only testing for m68k and vax at the moment); do verify that the
6237 preprocessor didn't trash the arch name inside the string version.
6238 Don't print out "pagesize =" line that prevents output from
6239 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
6241 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

6267 * som.c, som.h (bfd_som_set_section_attributes,
6268 bfd_som_set_subsection_attributes): Change parameters from char
6269 to int. Following a prototype with an old-style function definition
6270 in the presence of widened parameters is a GCC-ism not supported

6376 use get_value to get the symbol value and check for undefined
6378 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6379 undefined, look it up in the linker hash table.
6381 * aoutx.h (translate_symbol_table): The string index 0 has a

6406 The sparc (and possibly other?) NLM format requires a different
6407 way to write exports, so add a write_export field to the backend
6408 data (and set it to NULL for everything but the sparc).
