1715 an empty .plt section.
1716 (elf32_sparc_relocate_section): For a GOT reloc against a global
1717 symbol when no dynamic object was seen, initialize the contents of
1718 the .got section. For a GOT reloc against a local symbol, only

5242 (_bfd_generic_final_link): Likewise.
5243 (_bfd_generic_link_output_symbols): Likewise.

5246 in asymbol udata field.
5248 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5250 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
5251 reloc, used in embedded PIC code.
5252 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

5257 relocs when allocating space for relocations. Set SEC_RELOC flag
5258 for any section which has relocs. Handle link_order relocs in
5259 link_order loop. Use _bfd_generic_link_add_symbols_collect for
5260 add_symbls entry point.
5262 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5263 counting relocs. Set SEC_RELOC flag for any section which has

5268 * linker.c (_bfd_generic_link_add_symbols): Just call
5269 generic_link_add_symbols.
5270 (_bfd_generic_link_add_symbols_collect): New function, like
5271 _bfd_generic_link_add_symbols but also collect constructors and
5272 destructors by name as collect2 does.
5273 (generic_link_add_symbols): New function, like old
5274 _bfd_generic_link_add_symbols but with collect argument.
5275 (generic_link_add_object_symbols): Take collect argument.

5287 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
5288 for first character in an extended name.
5289 (_bfd_write_archive_contents): If ar_padchar == '/', then use
5290 "//" as the name of the special archive member holding the
5291 extended name table.
5293 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5295 Support for link_order types which generate relocs in order to
5296 support -Ur in the linker.
5297 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5298 from call to _bfd_generic_link_add_one_symbol.
5299 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5300 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5301 instead of bitsize to add_to_set call back.
5302 (_bfd_generic_final_link): Account for link_order relocs when
5303 allocating space for relocations. Handle them in link_order loop.
5304 (_bfd_generic_reloc_link_order): New function.
5305 (_bfd_default_link_order): If a reloc_link_order is seen here,
5307 (_bfd_count_link_order_relocs): New function.
5308 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5309 argument from declaration.
5310 (_bfd_generic_reloc_link_order): Declare.
5311 (_bfd_count_link_order_relocs): Declare.
5312 * libbfd.h: Rebuilt.
5313 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5314 call to _bfd_generic_link_add_one_symbol.
5315 (NAME(aout,final_link)): Account for link_order relocs when

5320 call to _bfd_generic_link_add_one_symbol.
5321 (ecoff_bfd_final_link): Account for link_order relocs when
5322 allocating space for relocations. Handle them in link_order loop.
5323 (ecoff_link_write_external): Set the storage class of a defined
5324 linker created symbol based on the section it is in. Correct
5325 bfd_link_hash_weak case to use .sc rather than .st.
5326 (ecoff_reloc_link_order): New function.
5327 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5329 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5334 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5335 bfd_zmalloc. Free a pointer, not a union.
5336 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5338 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5340 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5342 * som.c (bfd_section_from_som_symbol): Only to do the value
5343 comparison for function symbols within executables.
5345 * som.c (bfd_section_from_som_symbol): Renamed from
5346 som_section_from_subspace_index. Pass in a native SOM symbol.
5347 For executables, iterate through the sections to find out
5348 which contains the symbol's address rather than using the
5349 symbol_info field. (symbol_info has a different meaning for
5350 dynamicly linked executables.)
5352 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5355 * som.c (som_begin_writing): Fix braino (one call to align
5356 space/subspace data was done unconditionally rather than
5357 just for executables.)
5359 * som.c (som_begin_writing): Align text in all executables to
5360 make HPUX kernel happy. Fixes strip/objcopy for shared
5363 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5365 * som.c (som_begin_writing): Account for alignment needs of
5366 subspaces too when writing executables. Never request a negative
5367 bss size. Fixes some problems with demand paged executables,
5368 still having problems with pure executables and shared executables.
5370 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5372 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5373 bfd_zalloc for rawptr, because later on we may call free, not
5376 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5377 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5378 * cisco-core.c: New file.
5379 * Makefile.in: Change accordingly.
5380 * configure.in: Recognize cisco_core_vec.
5381 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5382 * targets.c: Add cisco_core_vec.
5383 * bfd-in2.h: Rebuilt.
5385 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5387 * som.h (som_copyable_section_data_struct): New structure
5388 containing all the private section information which needs
5389 to be copied from input section to output section during
5391 (som_section_data_struct): Remove several fields now in
5392 som_copyable_section_data_struct. Make the space and
5393 subspace dictionaries be pointers (to save space when
5394 only reading objects).
5396 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5397 some references changed. Allocate a copyable data stucture if
5398 none exists. Store info into the copyable data structure.
5399 (bfd_som_set_subsection_attributes): Likewise.
5400 (som_is_space, som_is_subspace, som_is_container): New functions.
5401 Use these instead of directly accessing private data.
5402 (som_prep_headers): Allocate space and subspace headers here.
5403 Fill in some fields in the space/subspace headers from the
5405 (som_bfd_copy_private_section_data): Only copy the stuff
5406 that we really need to make objcopy and strip work. Allocate
5407 the copy_data structure for the output bfd before copying.
5409 * som.h (struct som_exec_data): New structure to hold exec
5410 info that must be preserved when running objcopy/strip.
5411 (struct somdata): Add new "exec_data" field and accessor
5412 macro. Add some comments on how the various fields are used.
5413 (som_section_data_struct): Make is_space and is_subspace bitfields.
5414 Delete unused subspace_index. All references now use the
5415 target_index field within the section structure itself.
5417 * som.c (make_unique_section): Delete unused declaration.
5418 (som_bfd_copy_private_bfd_data): New function.
5419 (som_object_setup): Allocate space for and save exec information
5420 that needs to be copied during objcopy/strip.
5421 (som_mkobject): Do not allocate space for a file header here.
5422 It is not used when only reading SOM objects.
5423 (som_prep_headers): Allocate space for and attach a file header
5424 to the output bfd. For executables, use the saved system_id
5425 value rather than trying to guess the right value. Do not abort
5426 wwhen setting file_hdr->entry* for executables.
5427 (som_begin_writing): For executables, set the exec_entry and
5429 (som_copy_private_backend_section_data): Always return a value.
5431 * libhppa.h (PA_PAGESIZE): Define.
5433 * som.c (SOM_ALIGN): Define.
5434 (som_begin_writing): If writing an executable, initialize all
5435 fields in the exec header to zero. Update fields in the exec
5436 header as sizes of loadable subspaces are computed. Carefully
5437 preserve alignments when building executables. Actually write the
5438 exec after all the fields are filled in.
5440 * Better long-filename handling. Reads SOM ABI compliant extended
5441 names, but doesn't quite write compliant extended names yet.
5442 * som.c (som_slurp_extended_name_table): Delete function. The
5443 generic code will handle things correctly.
5444 (som_slurp_armap): Seek to the beginning of the next member.
5445 (normalize): New function.
5446 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5447 name table into account when computing the file offsets in the
5448 SOM dictionary. Make sure to align to an even boundary.
5449 (som_write_armap): Initialize the checksum to zero.
5450 (ar_maxchars): Fix. Opps.
5452 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5454 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5455 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5457 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5459 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5460 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5461 * bfd-in2.h: Regenerated.
5463 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5464 this was also named trad_unix_bfd_copy_private_bfd_data.
5466 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5468 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5469 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5470 returns NULL, it is not an error. It's possible that some of
5471 these checks are not necessary (because the size can never be
5472 zero), but putting in the checks is the conservative thing to do
5473 in light of the fact that some of these malloc calls replaced
5474 unchecked alloca calls, in which a zero argument would work fine.
5476 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5478 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5479 duplicate definition.
5480 (osf_core_bfd_is_local_label): Define.
5482 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5483 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5484 failure indication, it merely means there are no relocs.
5486 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5487 after NAME, since SunOS /bin/cc can't handle it.
5489 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5491 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5492 From sukes@glue.umd.edu (Tasuki Hirata).
5494 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5496 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5497 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5498 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5500 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5502 * som.c (som_prep_for_fixups): Detect section symbols based
5503 on either the lack of private data or the symbol flags. Do not
5504 munge section symbol names anymore -- they no longer confuse GDB.
5505 (som_begin_writing): Leave space for an exec header if writing
5507 (som_slurp_symbol_table): Recognize both forms of section symbol
5508 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5509 section symbols to be the name of the section they represent.
5510 Debugging symbols begin with "L$0\001", not just "L$".
5512 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5514 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5516 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5517 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5518 and bfd_is_local_label.
5520 * targets.c: Add new entries to the bfd_target structure.
5522 * bfd.c (bfd_copy_private_bfd_data): New definition.
5524 * section.c (bfd_copy_private_section_data): New definition.

5530 * libbfd.c (bfd_generic_is_local_label): New function.
5532 * *-core.c: Provide default definitions for new functions in
5533 the target vector which all point to bfd_false.
5535 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5536 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5537 Default new vectors for copying private backend data to bfd_true.
5538 Default new vector for determining if a symbol is a local label
5539 to bfd_generic_is_local_label.
5541 * som.c (som_bfd_copy_private_section_data): New function.
5542 (som_bfd_is_local_label): New function.
5543 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5545 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5547 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5549 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5551 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5554 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5555 Indent some of them to GNU standards.
5557 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5558 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5559 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5560 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5561 Update copyright years.
5563 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5565 * som.c (som_prep_for_fixups): A relocation involving the section
5566 symbol for the *ABS* section is really a relocation involving
5568 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5569 undefined symbols. Correctly distinguish between debugger symbols
5570 and section symbols.
5572 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5573 for spaces and subspaces.
5575 * som.c (som_bfd_count_ar_symbols): Fix typo.
5577 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5578 HAS_RELOC based on the object's magic number.
5579 (make_unique_section): Delete function. BFD and its users are
5580 prepared to handle multiple sections with the same name.
5581 (setup_sections): Allocate space on the BFD's obstack to hold
5582 section names. Use bfd_make_setion_anyway rather than the
5583 obsolete make_unique_section.
5584 (som_prep_headers): Choose the correct SOM magic number based
5586 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5588 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5590 * elf32-ppc.c: Renamed from elf32-powerpc.c.

5600 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5601 is always located at the start of the data section to allow
5602 recovery of the dynamic info from a stripped executable.
5603 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5606 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5608 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5609 cruft (like the #pragma alloca for AIX).
5610 In addition to that problem, the C alloca calls xmalloc, which
5611 means checking for being out of memory can't work right. The
5612 following changes remove all uses of alloca from BFD.
5613 * hosts/solaris2.h: Remove alloca cruft.
5614 * som.c: Replace alloca with a fixed size auto array.

5619 * linker.c: Replace alloca with obstack_alloc.
5620 * libbfd.h: Rebuilt.
5622 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5624 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5627 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5629 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5630 Elf*_Off typedefs by their expansion, the typedefs have been
5631 removed from include/elf/internal.h.
5632 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5633 SHT_PROGBITS section.
5635 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5637 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
5639 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5641 * configure.host: Recognize i[34]86-sequent-*.
5643 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5644 return from bfd_seek indicates an error.
5645 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5646 TRAD_CORE_STACK_OFFSET.
5647 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5648 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5650 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5652 * som.[ch]: Do not include libhppa.h in som.c, instead include
5655 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5656 include it in elf32-hppa.h.
5658 * som.c (log2): Return -1 on error rather than aborting.
5659 (setup_sections): Bubble up an error from log2.
5661 * Changes to make HP C compiler happy in both traditional
5663 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5665 (bfd_som_set_section_attributes): Use unsigned int rather than
5666 unsigned char to avoid GNU-C extensions.
5667 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5668 or failure rather than aborting on failure.
5670 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5672 (bfd_som_attach_aux_hdr): Add prototype.
5673 (hppa_som-gen_reloc_type): Likewise.
5675 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5676 (hppa_look_for_stubs_in_section): Do not return false on failure
5677 until rest of code is ready to handle it. Abort for now.

5787 COMPLEX relocation support (it's never used anyway).
5788 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5789 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5790 (elf_hppa_tc_make_sections): Likewise.

5962 (b_out_relax_section): If a section contains no relocations, don't
5963 bother processing them.
5964 (b_out_get_relocated_section_contents): Set reloc_done. Assert
5965 that bfd_get_section_contents returns true. Check that relocs are

6667 The sparc (and possibly other?) NLM format requires a different
6668 way to write exports, so add a write_export field to the backend
6669 data (and set it to NULL for everything but the sparc).
