2520 (elf_link_create_dynamic_sections): If dynamic sections were
2521 already created, don't do anything. If dynobj is already set, use
2522 it; otherwise, set it to the bfd argument. Don't initialize

2576 of the .plt section.
2577 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
2578 seen, skip most of this function, and force the size of the
2579 .rela.got section to zero. Strip empty reloc sections, and strip
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
2584 create a R_SPARC_RELATIVE reloc when generating a shared object.
2585 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
2586 create a PLT entry as a R_SPARC_WDISP30 reloc.
2587 (elf32_sparc_finish_dynamic_sections): Only fiddle with the

6103 to get the symbols from the BFD.
6104 (generic_link_check_archive_element): Likewise.
6105 (_bfd_generic_final_link): Likewise.
6106 (_bfd_generic_link_output_symbols): Likewise.

6109 in asymbol udata field.
6111 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6113 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
6114 reloc, used in embedded PIC code.

6122 link_order loop. Use _bfd_generic_link_add_symbols_collect for
6123 add_symbls entry point.
6125 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
6126 counting relocs. Set SEC_RELOC flag for any section which has

6131 * linker.c (_bfd_generic_link_add_symbols): Just call
6132 generic_link_add_symbols.
6133 (_bfd_generic_link_add_symbols_collect): New function, like
6134 _bfd_generic_link_add_symbols but also collect constructors and
6135 destructors by name as collect2 does.
6136 (generic_link_add_symbols): New function, like old
6137 _bfd_generic_link_add_symbols but with collect argument.
6138 (generic_link_add_object_symbols): Take collect argument.

6150 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
6151 for first character in an extended name.
6152 (_bfd_write_archive_contents): If ar_padchar == '/', then use
6153 "//" as the name of the special archive member holding the
6154 extended name table.
6156 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6158 Support for link_order types which generate relocs in order to
6159 support -Ur in the linker.
6160 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6161 from call to _bfd_generic_link_add_one_symbol.
6162 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6163 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6164 instead of bitsize to add_to_set call back.
6165 (_bfd_generic_final_link): Account for link_order relocs when
6166 allocating space for relocations. Handle them in link_order loop.
6167 (_bfd_generic_reloc_link_order): New function.
6168 (_bfd_default_link_order): If a reloc_link_order is seen here,
6170 (_bfd_count_link_order_relocs): New function.
6171 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
6172 argument from declaration.
6173 (_bfd_generic_reloc_link_order): Declare.
6174 (_bfd_count_link_order_relocs): Declare.

6176 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
6177 call to _bfd_generic_link_add_one_symbol.

6183 call to _bfd_generic_link_add_one_symbol.
6184 (ecoff_bfd_final_link): Account for link_order relocs when
6185 allocating space for relocations. Handle them in link_order loop.
6186 (ecoff_link_write_external): Set the storage class of a defined
6187 linker created symbol based on the section it is in. Correct
6188 bfd_link_hash_weak case to use .sc rather than .st.
6189 (ecoff_reloc_link_order): New function.
6190 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
6192 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

6198 bfd_zmalloc. Free a pointer, not a union.
6199 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
6201 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6203 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
6205 * som.c (bfd_section_from_som_symbol): Only to do the value
6206 comparison for function symbols within executables.
6208 * som.c (bfd_section_from_som_symbol): Renamed from
6209 som_section_from_subspace_index. Pass in a native SOM symbol.
6210 For executables, iterate through the sections to find out
6211 which contains the symbol's address rather than using the
6212 symbol_info field. (symbol_info has a different meaning for
6213 dynamicly linked executables.)
6215 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6218 * som.c (som_begin_writing): Fix braino (one call to align
6219 space/subspace data was done unconditionally rather than
6220 just for executables.)
6222 * som.c (som_begin_writing): Align text in all executables to
6223 make HPUX kernel happy. Fixes strip/objcopy for shared
6226 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6228 * som.c (som_begin_writing): Account for alignment needs of
6229 subspaces too when writing executables. Never request a negative
6230 bss size. Fixes some problems with demand paged executables,
6231 still having problems with pure executables and shared executables.
6233 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6235 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6236 bfd_zalloc for rawptr, because later on we may call free, not
6239 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6240 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6241 * cisco-core.c: New file.
6242 * Makefile.in: Change accordingly.
6243 * configure.in: Recognize cisco_core_vec.
6244 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6245 * targets.c: Add cisco_core_vec.
6246 * bfd-in2.h: Rebuilt.
6248 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6250 * som.h (som_copyable_section_data_struct): New structure
6251 containing all the private section information which needs
6252 to be copied from input section to output section during
6254 (som_section_data_struct): Remove several fields now in
6255 som_copyable_section_data_struct. Make the space and
6256 subspace dictionaries be pointers (to save space when
6257 only reading objects).
6259 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6260 some references changed. Allocate a copyable data stucture if
6261 none exists. Store info into the copyable data structure.
6262 (bfd_som_set_subsection_attributes): Likewise.
6263 (som_is_space, som_is_subspace, som_is_container): New functions.
6264 Use these instead of directly accessing private data.
6265 (som_prep_headers): Allocate space and subspace headers here.
6266 Fill in some fields in the space/subspace headers from the
6268 (som_bfd_copy_private_section_data): Only copy the stuff
6269 that we really need to make objcopy and strip work. Allocate
6270 the copy_data structure for the output bfd before copying.
6272 * som.h (struct som_exec_data): New structure to hold exec
6273 info that must be preserved when running objcopy/strip.
6274 (struct somdata): Add new "exec_data" field and accessor
6275 macro. Add some comments on how the various fields are used.
6276 (som_section_data_struct): Make is_space and is_subspace bitfields.
6277 Delete unused subspace_index. All references now use the
6278 target_index field within the section structure itself.
6280 * som.c (make_unique_section): Delete unused declaration.
6281 (som_bfd_copy_private_bfd_data): New function.
6282 (som_object_setup): Allocate space for and save exec information
6283 that needs to be copied during objcopy/strip.
6284 (som_mkobject): Do not allocate space for a file header here.
6285 It is not used when only reading SOM objects.
6286 (som_prep_headers): Allocate space for and attach a file header
6287 to the output bfd. For executables, use the saved system_id
6288 value rather than trying to guess the right value. Do not abort
6289 wwhen setting file_hdr->entry* for executables.
6290 (som_begin_writing): For executables, set the exec_entry and
6292 (som_copy_private_backend_section_data): Always return a value.
6294 * libhppa.h (PA_PAGESIZE): Define.
6296 * som.c (SOM_ALIGN): Define.
6297 (som_begin_writing): If writing an executable, initialize all
6298 fields in the exec header to zero. Update fields in the exec
6299 header as sizes of loadable subspaces are computed. Carefully
6300 preserve alignments when building executables. Actually write the
6301 exec after all the fields are filled in.
6303 * Better long-filename handling. Reads SOM ABI compliant extended
6304 names, but doesn't quite write compliant extended names yet.
6305 * som.c (som_slurp_extended_name_table): Delete function. The
6306 generic code will handle things correctly.
6307 (som_slurp_armap): Seek to the beginning of the next member.
6308 (normalize): New function.
6309 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6310 name table into account when computing the file offsets in the
6311 SOM dictionary. Make sure to align to an even boundary.
6312 (som_write_armap): Initialize the checksum to zero.
6313 (ar_maxchars): Fix. Opps.
6315 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6317 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6318 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6320 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6322 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6323 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6324 * bfd-in2.h: Regenerated.
6326 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6327 this was also named trad_unix_bfd_copy_private_bfd_data.
6329 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6331 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6332 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6333 returns NULL, it is not an error. It's possible that some of
6334 these checks are not necessary (because the size can never be
6335 zero), but putting in the checks is the conservative thing to do
6336 in light of the fact that some of these malloc calls replaced
6337 unchecked alloca calls, in which a zero argument would work fine.
6339 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6341 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6342 duplicate definition.
6343 (osf_core_bfd_is_local_label): Define.
6345 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6346 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6347 failure indication, it merely means there are no relocs.
6349 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6350 after NAME, since SunOS /bin/cc can't handle it.
6352 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6354 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6355 From sukes@glue.umd.edu (Tasuki Hirata).
6357 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6359 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6360 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6361 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6363 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6365 * som.c (som_prep_for_fixups): Detect section symbols based
6366 on either the lack of private data or the symbol flags. Do not
6367 munge section symbol names anymore -- they no longer confuse GDB.
6368 (som_begin_writing): Leave space for an exec header if writing
6370 (som_slurp_symbol_table): Recognize both forms of section symbol
6371 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6372 section symbols to be the name of the section they represent.
6373 Debugging symbols begin with "L$0\001", not just "L$".
6375 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6377 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6379 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6380 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6381 and bfd_is_local_label.
6383 * targets.c: Add new entries to the bfd_target structure.
6385 * bfd.c (bfd_copy_private_bfd_data): New definition.
6387 * section.c (bfd_copy_private_section_data): New definition.
6389 * syms.c (bfd_is_local_label): New definition.
6391 * libbfd-in.h (bfd_generic_is_local_label): Declare.
6393 * libbfd.c (bfd_generic_is_local_label): New function.
6395 * *-core.c: Provide default definitions for new functions in
6396 the target vector which all point to bfd_false.
6398 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6399 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6400 Default new vectors for copying private backend data to bfd_true.
6401 Default new vector for determining if a symbol is a local label
6402 to bfd_generic_is_local_label.
6404 * som.c (som_bfd_copy_private_section_data): New function.
6405 (som_bfd_is_local_label): New function.
6406 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6408 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6410 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6412 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6414 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6417 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6418 Indent some of them to GNU standards.
6420 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6421 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6422 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6423 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6424 Update copyright years.
6426 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6428 * som.c (som_prep_for_fixups): A relocation involving the section
6429 symbol for the *ABS* section is really a relocation involving
6431 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6432 undefined symbols. Correctly distinguish between debugger symbols
6433 and section symbols.
6435 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6436 for spaces and subspaces.
6438 * som.c (som_bfd_count_ar_symbols): Fix typo.
6440 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6441 HAS_RELOC based on the object's magic number.
6442 (make_unique_section): Delete function. BFD and its users are
6443 prepared to handle multiple sections with the same name.
6444 (setup_sections): Allocate space on the BFD's obstack to hold
6445 section names. Use bfd_make_setion_anyway rather than the
6446 obsolete make_unique_section.
6447 (som_prep_headers): Choose the correct SOM magic number based
6449 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6451 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6453 * elf32-ppc.c: Renamed from elf32-powerpc.c.

6463 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6464 is always located at the start of the data section to allow
6465 recovery of the dynamic info from a stripped executable.
6466 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6469 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6471 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6472 cruft (like the #pragma alloca for AIX).
6473 In addition to that problem, the C alloca calls xmalloc, which
6474 means checking for being out of memory can't work right. The
6475 following changes remove all uses of alloca from BFD.
6476 * hosts/solaris2.h: Remove alloca cruft.
6477 * som.c: Replace alloca with a fixed size auto array.
6478 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

6482 * linker.c: Replace alloca with obstack_alloc.
6483 * libbfd.h: Rebuilt.
6485 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6487 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6490 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6492 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6493 Elf*_Off typedefs by their expansion, the typedefs have been
6494 removed from include/elf/internal.h.
6495 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6496 SHT_PROGBITS section.
6498 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6500 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

6504 * configure.host: Recognize i[34]86-sequent-*.
6506 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6507 return from bfd_seek indicates an error.
6508 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6509 TRAD_CORE_STACK_OFFSET.
6510 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6511 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6513 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6515 * som.[ch]: Do not include libhppa.h in som.c, instead include
6518 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6519 include it in elf32-hppa.h.
6521 * som.c (log2): Return -1 on error rather than aborting.
6522 (setup_sections): Bubble up an error from log2.
6524 * Changes to make HP C compiler happy in both traditional
6526 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6528 (bfd_som_set_section_attributes): Use unsigned int rather than
6529 unsigned char to avoid GNU-C extensions.
6530 (bfd_som_attach_aux_hdr): Return a boolean to indicate success

6825 (b_out_relax_section): If a section contains no relocations, don't
6826 bother processing them.
6827 (b_out_get_relocated_section_contents): Set reloc_done. Assert

7530 The sparc (and possibly other?) NLM format requires a different
7531 way to write exports, so add a write_export field to the backend
7532 data (and set it to NULL for everything but the sparc).
