1476 don't lose the memory forever.
1477 (_bfd_construct_extended_name_table): Check the name of an archive
1478 entry which is not being extended, and correct it if it is wrong.

1567 (elf32_sparc_adjust_dynindx): New static function.
1568 (elf32_sparc_relocate_section): When copying a reloc into a shared

1686 (elf_link_create_dynamic_sections): If dynamic sections were
1687 already created, don't do anything. If dynobj is already set, use
1688 it; otherwise, set it to the bfd argument. Don't initialize

1742 of the .plt section.
1743 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
1744 seen, skip most of this function, and force the size of the
1745 .rela.got section to zero. Strip empty reloc sections, and strip
1746 an empty .plt section.
1747 (elf32_sparc_relocate_section): For a GOT reloc against a global
1748 symbol when no dynamic object was seen, initialize the contents of
1749 the .got section. For a GOT reloc against a local symbol, only

1751 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1752 create a PLT entry as a R_SPARC_WDISP30 reloc.

5277 in asymbol udata field.
5279 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5281 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
5282 reloc, used in embedded PIC code.
5283 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

5290 link_order loop. Use _bfd_generic_link_add_symbols_collect for
5291 add_symbls entry point.
5293 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5294 counting relocs. Set SEC_RELOC flag for any section which has

5300 generic_link_add_symbols.
5301 (_bfd_generic_link_add_symbols_collect): New function, like
5302 _bfd_generic_link_add_symbols but also collect constructors and
5303 destructors by name as collect2 does.
5304 (generic_link_add_symbols): New function, like old
5305 _bfd_generic_link_add_symbols but with collect argument.
5306 (generic_link_add_object_symbols): Take collect argument.

5318 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
5319 for first character in an extended name.
5320 (_bfd_write_archive_contents): If ar_padchar == '/', then use
5321 "//" as the name of the special archive member holding the
5322 extended name table.
5324 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5326 Support for link_order types which generate relocs in order to
5327 support -Ur in the linker.
5328 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5329 from call to _bfd_generic_link_add_one_symbol.
5330 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5331 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5332 instead of bitsize to add_to_set call back.
5333 (_bfd_generic_final_link): Account for link_order relocs when
5334 allocating space for relocations. Handle them in link_order loop.
5335 (_bfd_generic_reloc_link_order): New function.
5336 (_bfd_default_link_order): If a reloc_link_order is seen here,
5338 (_bfd_count_link_order_relocs): New function.
5339 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5340 argument from declaration.
5341 (_bfd_generic_reloc_link_order): Declare.
5342 (_bfd_count_link_order_relocs): Declare.

5344 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5345 call to _bfd_generic_link_add_one_symbol.

5352 (ecoff_bfd_final_link): Account for link_order relocs when
5353 allocating space for relocations. Handle them in link_order loop.
5354 (ecoff_link_write_external): Set the storage class of a defined
5355 linker created symbol based on the section it is in. Correct
5356 bfd_link_hash_weak case to use .sc rather than .st.
5357 (ecoff_reloc_link_order): New function.
5358 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5360 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5365 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5366 bfd_zmalloc. Free a pointer, not a union.
5367 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5369 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5371 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5373 * som.c (bfd_section_from_som_symbol): Only to do the value
5374 comparison for function symbols within executables.
5376 * som.c (bfd_section_from_som_symbol): Renamed from
5377 som_section_from_subspace_index. Pass in a native SOM symbol.
5378 For executables, iterate through the sections to find out
5379 which contains the symbol's address rather than using the
5380 symbol_info field. (symbol_info has a different meaning for
5381 dynamicly linked executables.)
5383 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5386 * som.c (som_begin_writing): Fix braino (one call to align
5387 space/subspace data was done unconditionally rather than
5388 just for executables.)
5390 * som.c (som_begin_writing): Align text in all executables to
5391 make HPUX kernel happy. Fixes strip/objcopy for shared
5394 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5396 * som.c (som_begin_writing): Account for alignment needs of
5397 subspaces too when writing executables. Never request a negative
5398 bss size. Fixes some problems with demand paged executables,
5399 still having problems with pure executables and shared executables.
5401 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5403 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5404 bfd_zalloc for rawptr, because later on we may call free, not
5407 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5408 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5409 * cisco-core.c: New file.
5410 * Makefile.in: Change accordingly.
5411 * configure.in: Recognize cisco_core_vec.
5412 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5413 * targets.c: Add cisco_core_vec.
5414 * bfd-in2.h: Rebuilt.
5416 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5418 * som.h (som_copyable_section_data_struct): New structure
5419 containing all the private section information which needs
5420 to be copied from input section to output section during
5422 (som_section_data_struct): Remove several fields now in
5423 som_copyable_section_data_struct. Make the space and
5424 subspace dictionaries be pointers (to save space when
5425 only reading objects).
5427 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5428 some references changed. Allocate a copyable data stucture if
5429 none exists. Store info into the copyable data structure.
5430 (bfd_som_set_subsection_attributes): Likewise.
5431 (som_is_space, som_is_subspace, som_is_container): New functions.
5432 Use these instead of directly accessing private data.
5433 (som_prep_headers): Allocate space and subspace headers here.
5434 Fill in some fields in the space/subspace headers from the
5436 (som_bfd_copy_private_section_data): Only copy the stuff
5437 that we really need to make objcopy and strip work. Allocate
5438 the copy_data structure for the output bfd before copying.
5440 * som.h (struct som_exec_data): New structure to hold exec
5441 info that must be preserved when running objcopy/strip.
5442 (struct somdata): Add new "exec_data" field and accessor
5443 macro. Add some comments on how the various fields are used.
5444 (som_section_data_struct): Make is_space and is_subspace bitfields.
5445 Delete unused subspace_index. All references now use the
5446 target_index field within the section structure itself.
5448 * som.c (make_unique_section): Delete unused declaration.
5449 (som_bfd_copy_private_bfd_data): New function.
5450 (som_object_setup): Allocate space for and save exec information
5451 that needs to be copied during objcopy/strip.
5452 (som_mkobject): Do not allocate space for a file header here.
5453 It is not used when only reading SOM objects.
5454 (som_prep_headers): Allocate space for and attach a file header
5455 to the output bfd. For executables, use the saved system_id
5456 value rather than trying to guess the right value. Do not abort
5457 wwhen setting file_hdr->entry* for executables.
5458 (som_begin_writing): For executables, set the exec_entry and
5460 (som_copy_private_backend_section_data): Always return a value.
5462 * libhppa.h (PA_PAGESIZE): Define.
5464 * som.c (SOM_ALIGN): Define.
5465 (som_begin_writing): If writing an executable, initialize all
5466 fields in the exec header to zero. Update fields in the exec
5467 header as sizes of loadable subspaces are computed. Carefully
5468 preserve alignments when building executables. Actually write the
5469 exec after all the fields are filled in.
5471 * Better long-filename handling. Reads SOM ABI compliant extended
5472 names, but doesn't quite write compliant extended names yet.
5473 * som.c (som_slurp_extended_name_table): Delete function. The
5474 generic code will handle things correctly.
5475 (som_slurp_armap): Seek to the beginning of the next member.
5476 (normalize): New function.
5477 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5478 name table into account when computing the file offsets in the
5479 SOM dictionary. Make sure to align to an even boundary.
5480 (som_write_armap): Initialize the checksum to zero.
5481 (ar_maxchars): Fix. Opps.
5483 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5485 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5486 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5488 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5490 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5491 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5492 * bfd-in2.h: Regenerated.
5494 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5495 this was also named trad_unix_bfd_copy_private_bfd_data.
5497 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5499 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5500 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5501 returns NULL, it is not an error. It's possible that some of
5502 these checks are not necessary (because the size can never be
5503 zero), but putting in the checks is the conservative thing to do
5504 in light of the fact that some of these malloc calls replaced
5505 unchecked alloca calls, in which a zero argument would work fine.
5507 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5509 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5510 duplicate definition.
5511 (osf_core_bfd_is_local_label): Define.
5513 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5514 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5515 failure indication, it merely means there are no relocs.
5517 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5518 after NAME, since SunOS /bin/cc can't handle it.
5520 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5522 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5523 From sukes@glue.umd.edu (Tasuki Hirata).
5525 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5527 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5528 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5529 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5531 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5533 * som.c (som_prep_for_fixups): Detect section symbols based
5534 on either the lack of private data or the symbol flags. Do not
5535 munge section symbol names anymore -- they no longer confuse GDB.
5536 (som_begin_writing): Leave space for an exec header if writing
5538 (som_slurp_symbol_table): Recognize both forms of section symbol
5539 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5540 section symbols to be the name of the section they represent.
5541 Debugging symbols begin with "L$0\001", not just "L$".
5543 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5545 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5547 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5548 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5549 and bfd_is_local_label.
5551 * targets.c: Add new entries to the bfd_target structure.
5553 * bfd.c (bfd_copy_private_bfd_data): New definition.
5555 * section.c (bfd_copy_private_section_data): New definition.
5557 * syms.c (bfd_is_local_label): New definition.
5559 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5561 * libbfd.c (bfd_generic_is_local_label): New function.
5563 * *-core.c: Provide default definitions for new functions in
5564 the target vector which all point to bfd_false.
5566 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5567 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5568 Default new vectors for copying private backend data to bfd_true.
5569 Default new vector for determining if a symbol is a local label
5570 to bfd_generic_is_local_label.
5572 * som.c (som_bfd_copy_private_section_data): New function.
5573 (som_bfd_is_local_label): New function.
5574 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5576 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5578 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5580 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5582 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5585 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5586 Indent some of them to GNU standards.
5588 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5589 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5590 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5591 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5592 Update copyright years.
5594 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5596 * som.c (som_prep_for_fixups): A relocation involving the section
5597 symbol for the *ABS* section is really a relocation involving
5599 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5600 undefined symbols. Correctly distinguish between debugger symbols
5601 and section symbols.
5603 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5604 for spaces and subspaces.
5606 * som.c (som_bfd_count_ar_symbols): Fix typo.
5608 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5609 HAS_RELOC based on the object's magic number.
5610 (make_unique_section): Delete function. BFD and its users are
5611 prepared to handle multiple sections with the same name.
5612 (setup_sections): Allocate space on the BFD's obstack to hold
5613 section names. Use bfd_make_setion_anyway rather than the
5614 obsolete make_unique_section.
5615 (som_prep_headers): Choose the correct SOM magic number based
5617 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5619 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5621 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5622 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.

5631 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5632 is always located at the start of the data section to allow
5633 recovery of the dynamic info from a stripped executable.
5634 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5637 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5639 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5640 cruft (like the #pragma alloca for AIX).
5641 In addition to that problem, the C alloca calls xmalloc, which
5642 means checking for being out of memory can't work right. The
5643 following changes remove all uses of alloca from BFD.
5644 * hosts/solaris2.h: Remove alloca cruft.
5645 * som.c: Replace alloca with a fixed size auto array.

5650 * linker.c: Replace alloca with obstack_alloc.
5651 * libbfd.h: Rebuilt.
5653 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5655 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5658 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5660 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5661 Elf*_Off typedefs by their expansion, the typedefs have been
5662 removed from include/elf/internal.h.
5663 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5664 SHT_PROGBITS section.
5666 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5668 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
5670 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5672 * configure.host: Recognize i[34]86-sequent-*.
5674 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5675 return from bfd_seek indicates an error.
5676 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5677 TRAD_CORE_STACK_OFFSET.
5678 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and

5994 bother processing them.
5995 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6482 _bfd_generic_link_write_global_symbol): Don't require that all

6560 bfd_som_set_subsection_attributes): Change parameters from char
6561 to int. Following a prototype with an old-style function definition

6698 The sparc (and possibly other?) NLM format requires a different
6699 way to write exports, so add a write_export field to the backend
6700 data (and set it to NULL for everything but the sparc).
