2580 an empty .plt section.
2581 (elf32_sparc_relocate_section): For a GOT reloc against a global
2582 symbol when no dynamic object was seen, initialize the contents of
2583 the .got section. For a GOT reloc against a local symbol, only

6107 (_bfd_generic_final_link): Likewise.
6108 (_bfd_generic_link_output_symbols): Likewise.

6111 in asymbol udata field.
6113 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6115 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
6116 reloc, used in embedded PIC code.

6124 link_order loop. Use _bfd_generic_link_add_symbols_collect for
6125 add_symbls entry point.
6127 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
6128 counting relocs. Set SEC_RELOC flag for any section which has

6133 * linker.c (_bfd_generic_link_add_symbols): Just call
6134 generic_link_add_symbols.
6135 (_bfd_generic_link_add_symbols_collect): New function, like
6136 _bfd_generic_link_add_symbols but also collect constructors and
6137 destructors by name as collect2 does.
6138 (generic_link_add_symbols): New function, like old
6139 _bfd_generic_link_add_symbols but with collect argument.
6140 (generic_link_add_object_symbols): Take collect argument.

6152 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
6153 for first character in an extended name.
6154 (_bfd_write_archive_contents): If ar_padchar == '/', then use
6155 "//" as the name of the special archive member holding the
6156 extended name table.
6158 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6160 Support for link_order types which generate relocs in order to
6161 support -Ur in the linker.
6162 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6163 from call to _bfd_generic_link_add_one_symbol.
6164 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6165 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6166 instead of bitsize to add_to_set call back.
6167 (_bfd_generic_final_link): Account for link_order relocs when
6168 allocating space for relocations. Handle them in link_order loop.
6169 (_bfd_generic_reloc_link_order): New function.
6170 (_bfd_default_link_order): If a reloc_link_order is seen here,
6172 (_bfd_count_link_order_relocs): New function.
6173 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
6174 argument from declaration.
6175 (_bfd_generic_reloc_link_order): Declare.
6176 (_bfd_count_link_order_relocs): Declare.
6177 * libbfd.h: Rebuilt.
6178 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
6179 call to _bfd_generic_link_add_one_symbol.
6180 (NAME(aout,final_link)): Account for link_order relocs when

6185 call to _bfd_generic_link_add_one_symbol.
6186 (ecoff_bfd_final_link): Account for link_order relocs when
6187 allocating space for relocations. Handle them in link_order loop.
6188 (ecoff_link_write_external): Set the storage class of a defined
6189 linker created symbol based on the section it is in. Correct
6190 bfd_link_hash_weak case to use .sc rather than .st.
6191 (ecoff_reloc_link_order): New function.
6192 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
6194 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

6199 * cisco-core.c (cisco_core_file_p): Only pass one argument to
6200 bfd_zmalloc. Free a pointer, not a union.
6201 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
6203 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6205 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
6207 * som.c (bfd_section_from_som_symbol): Only to do the value
6208 comparison for function symbols within executables.
6210 * som.c (bfd_section_from_som_symbol): Renamed from
6211 som_section_from_subspace_index. Pass in a native SOM symbol.
6212 For executables, iterate through the sections to find out
6213 which contains the symbol's address rather than using the
6214 symbol_info field. (symbol_info has a different meaning for
6215 dynamicly linked executables.)
6217 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6220 * som.c (som_begin_writing): Fix braino (one call to align
6221 space/subspace data was done unconditionally rather than
6222 just for executables.)
6224 * som.c (som_begin_writing): Align text in all executables to
6225 make HPUX kernel happy. Fixes strip/objcopy for shared
6228 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6230 * som.c (som_begin_writing): Account for alignment needs of
6231 subspaces too when writing executables. Never request a negative
6232 bss size. Fixes some problems with demand paged executables,
6233 still having problems with pure executables and shared executables.
6235 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6237 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6238 bfd_zalloc for rawptr, because later on we may call free, not
6241 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6242 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6243 * cisco-core.c: New file.
6244 * Makefile.in: Change accordingly.
6245 * configure.in: Recognize cisco_core_vec.
6246 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6247 * targets.c: Add cisco_core_vec.
6248 * bfd-in2.h: Rebuilt.
6250 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6252 * som.h (som_copyable_section_data_struct): New structure
6253 containing all the private section information which needs
6254 to be copied from input section to output section during
6256 (som_section_data_struct): Remove several fields now in
6257 som_copyable_section_data_struct. Make the space and
6258 subspace dictionaries be pointers (to save space when
6259 only reading objects).
6261 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6262 some references changed. Allocate a copyable data stucture if
6263 none exists. Store info into the copyable data structure.
6264 (bfd_som_set_subsection_attributes): Likewise.
6265 (som_is_space, som_is_subspace, som_is_container): New functions.
6266 Use these instead of directly accessing private data.
6267 (som_prep_headers): Allocate space and subspace headers here.
6268 Fill in some fields in the space/subspace headers from the
6270 (som_bfd_copy_private_section_data): Only copy the stuff
6271 that we really need to make objcopy and strip work. Allocate
6272 the copy_data structure for the output bfd before copying.
6274 * som.h (struct som_exec_data): New structure to hold exec
6275 info that must be preserved when running objcopy/strip.
6276 (struct somdata): Add new "exec_data" field and accessor
6277 macro. Add some comments on how the various fields are used.
6278 (som_section_data_struct): Make is_space and is_subspace bitfields.
6279 Delete unused subspace_index. All references now use the
6280 target_index field within the section structure itself.
6282 * som.c (make_unique_section): Delete unused declaration.
6283 (som_bfd_copy_private_bfd_data): New function.
6284 (som_object_setup): Allocate space for and save exec information
6285 that needs to be copied during objcopy/strip.
6286 (som_mkobject): Do not allocate space for a file header here.
6287 It is not used when only reading SOM objects.
6288 (som_prep_headers): Allocate space for and attach a file header
6289 to the output bfd. For executables, use the saved system_id
6290 value rather than trying to guess the right value. Do not abort
6291 wwhen setting file_hdr->entry* for executables.
6292 (som_begin_writing): For executables, set the exec_entry and
6294 (som_copy_private_backend_section_data): Always return a value.
6296 * libhppa.h (PA_PAGESIZE): Define.
6298 * som.c (SOM_ALIGN): Define.
6299 (som_begin_writing): If writing an executable, initialize all
6300 fields in the exec header to zero. Update fields in the exec
6301 header as sizes of loadable subspaces are computed. Carefully
6302 preserve alignments when building executables. Actually write the
6303 exec after all the fields are filled in.
6305 * Better long-filename handling. Reads SOM ABI compliant extended
6306 names, but doesn't quite write compliant extended names yet.
6307 * som.c (som_slurp_extended_name_table): Delete function. The
6308 generic code will handle things correctly.
6309 (som_slurp_armap): Seek to the beginning of the next member.
6310 (normalize): New function.
6311 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6312 name table into account when computing the file offsets in the
6313 SOM dictionary. Make sure to align to an even boundary.
6314 (som_write_armap): Initialize the checksum to zero.
6315 (ar_maxchars): Fix. Opps.
6317 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6319 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6320 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6322 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6324 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6325 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6326 * bfd-in2.h: Regenerated.
6328 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6329 this was also named trad_unix_bfd_copy_private_bfd_data.
6331 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6333 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6334 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6335 returns NULL, it is not an error. It's possible that some of
6336 these checks are not necessary (because the size can never be
6337 zero), but putting in the checks is the conservative thing to do
6338 in light of the fact that some of these malloc calls replaced
6339 unchecked alloca calls, in which a zero argument would work fine.
6341 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6343 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6344 duplicate definition.
6345 (osf_core_bfd_is_local_label): Define.
6347 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6348 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6349 failure indication, it merely means there are no relocs.
6351 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6352 after NAME, since SunOS /bin/cc can't handle it.
6354 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6356 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6357 From sukes@glue.umd.edu (Tasuki Hirata).
6359 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6361 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6362 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6363 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6365 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6367 * som.c (som_prep_for_fixups): Detect section symbols based
6368 on either the lack of private data or the symbol flags. Do not
6369 munge section symbol names anymore -- they no longer confuse GDB.
6370 (som_begin_writing): Leave space for an exec header if writing
6372 (som_slurp_symbol_table): Recognize both forms of section symbol
6373 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6374 section symbols to be the name of the section they represent.
6375 Debugging symbols begin with "L$0\001", not just "L$".
6377 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6379 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6381 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6382 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6383 and bfd_is_local_label.
6385 * targets.c: Add new entries to the bfd_target structure.
6387 * bfd.c (bfd_copy_private_bfd_data): New definition.
6389 * section.c (bfd_copy_private_section_data): New definition.
6391 * syms.c (bfd_is_local_label): New definition.
6393 * libbfd-in.h (bfd_generic_is_local_label): Declare.
6395 * libbfd.c (bfd_generic_is_local_label): New function.
6397 * *-core.c: Provide default definitions for new functions in
6398 the target vector which all point to bfd_false.
6400 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6401 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6402 Default new vectors for copying private backend data to bfd_true.
6403 Default new vector for determining if a symbol is a local label
6404 to bfd_generic_is_local_label.
6406 * som.c (som_bfd_copy_private_section_data): New function.
6407 (som_bfd_is_local_label): New function.
6408 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6410 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6412 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6414 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6416 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6419 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6420 Indent some of them to GNU standards.
6422 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6423 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6424 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6425 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6426 Update copyright years.
6428 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6430 * som.c (som_prep_for_fixups): A relocation involving the section
6431 symbol for the *ABS* section is really a relocation involving
6433 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6434 undefined symbols. Correctly distinguish between debugger symbols
6435 and section symbols.
6437 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6438 for spaces and subspaces.
6440 * som.c (som_bfd_count_ar_symbols): Fix typo.
6442 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6443 HAS_RELOC based on the object's magic number.
6444 (make_unique_section): Delete function. BFD and its users are
6445 prepared to handle multiple sections with the same name.
6446 (setup_sections): Allocate space on the BFD's obstack to hold
6447 section names. Use bfd_make_setion_anyway rather than the
6448 obsolete make_unique_section.
6449 (som_prep_headers): Choose the correct SOM magic number based
6451 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6453 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6455 * elf32-ppc.c: Renamed from elf32-powerpc.c.

6465 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6466 is always located at the start of the data section to allow
6467 recovery of the dynamic info from a stripped executable.
6468 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6471 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6473 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6474 cruft (like the #pragma alloca for AIX).
6475 In addition to that problem, the C alloca calls xmalloc, which
6476 means checking for being out of memory can't work right. The
6477 following changes remove all uses of alloca from BFD.
6478 * hosts/solaris2.h: Remove alloca cruft.
6479 * som.c: Replace alloca with a fixed size auto array.

6484 * linker.c: Replace alloca with obstack_alloc.
6485 * libbfd.h: Rebuilt.
6487 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6489 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6492 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6494 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6495 Elf*_Off typedefs by their expansion, the typedefs have been
6496 removed from include/elf/internal.h.
6497 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6498 SHT_PROGBITS section.
6500 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6502 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

6506 * configure.host: Recognize i[34]86-sequent-*.
6508 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6509 return from bfd_seek indicates an error.
6510 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6511 TRAD_CORE_STACK_OFFSET.
6512 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6513 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6515 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6517 * som.[ch]: Do not include libhppa.h in som.c, instead include
6520 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6521 include it in elf32-hppa.h.
6523 * som.c (log2): Return -1 on error rather than aborting.
6524 (setup_sections): Bubble up an error from log2.
6526 * Changes to make HP C compiler happy in both traditional
6528 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6530 (bfd_som_set_section_attributes): Use unsigned int rather than
6531 unsigned char to avoid GNU-C extensions.
6532 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6533 or failure rather than aborting on failure.
6535 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6537 (bfd_som_attach_aux_hdr): Add prototype.
6538 (hppa_som-gen_reloc_type): Likewise.
6540 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6541 (hppa_look_for_stubs_in_section): Do not return false on failure
6542 until rest of code is ready to handle it. Abort for now.
6544 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6546 * bfd-in2.h: Rebuilt.
6548 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
6550 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

6652 COMPLEX relocation support (it's never used anyway).
6653 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
6654 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
6655 (elf_hppa_tc_make_sections): Likewise.

6827 (b_out_relax_section): If a section contains no relocations, don't
6828 bother processing them.
6829 (b_out_get_relocated_section_contents): Set reloc_done. Assert

7532 The sparc (and possibly other?) NLM format requires a different
7533 way to write exports, so add a write_export field to the backend
7534 data (and set it to NULL for everything but the sparc).
