1774 of the .plt section.
1775 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
1776 seen, skip most of this function, and force the size of the

1778 an empty .plt section.
1779 (elf32_sparc_relocate_section): For a GOT reloc against a global
1780 symbol when no dynamic object was seen, initialize the contents of
1781 the .got section. For a GOT reloc against a local symbol, only

1783 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1784 create a PLT entry as a R_SPARC_WDISP30 reloc.

5311 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5313 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
5314 reloc, used in embedded PIC code.
5315 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

5334 _bfd_generic_link_add_symbols but also collect constructors and
5335 destructors by name as collect2 does.

5354 extended name table.
5356 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5358 Support for link_order types which generate relocs in order to
5359 support -Ur in the linker.
5360 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5361 from call to _bfd_generic_link_add_one_symbol.
5362 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5363 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5364 instead of bitsize to add_to_set call back.
5365 (_bfd_generic_final_link): Account for link_order relocs when
5366 allocating space for relocations. Handle them in link_order loop.
5367 (_bfd_generic_reloc_link_order): New function.

5385 allocating space for relocations. Handle them in link_order loop.
5386 (ecoff_link_write_external): Set the storage class of a defined
5387 linker created symbol based on the section it is in. Correct
5388 bfd_link_hash_weak case to use .sc rather than .st.

5401 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5403 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5405 * som.c (bfd_section_from_som_symbol): Only to do the value
5406 comparison for function symbols within executables.
5408 * som.c (bfd_section_from_som_symbol): Renamed from
5409 som_section_from_subspace_index. Pass in a native SOM symbol.
5410 For executables, iterate through the sections to find out
5411 which contains the symbol's address rather than using the
5412 symbol_info field. (symbol_info has a different meaning for
5413 dynamicly linked executables.)
5415 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5418 * som.c (som_begin_writing): Fix braino (one call to align
5419 space/subspace data was done unconditionally rather than
5420 just for executables.)
5422 * som.c (som_begin_writing): Align text in all executables to
5423 make HPUX kernel happy. Fixes strip/objcopy for shared
5426 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5428 * som.c (som_begin_writing): Account for alignment needs of
5429 subspaces too when writing executables. Never request a negative
5430 bss size. Fixes some problems with demand paged executables,
5431 still having problems with pure executables and shared executables.
5433 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5435 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5436 bfd_zalloc for rawptr, because later on we may call free, not
5439 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5440 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5441 * cisco-core.c: New file.
5442 * Makefile.in: Change accordingly.
5443 * configure.in: Recognize cisco_core_vec.
5444 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5445 * targets.c: Add cisco_core_vec.
5446 * bfd-in2.h: Rebuilt.
5448 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5450 * som.h (som_copyable_section_data_struct): New structure
5451 containing all the private section information which needs
5452 to be copied from input section to output section during
5454 (som_section_data_struct): Remove several fields now in
5455 som_copyable_section_data_struct. Make the space and
5456 subspace dictionaries be pointers (to save space when
5457 only reading objects).
5459 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5460 some references changed. Allocate a copyable data stucture if
5461 none exists. Store info into the copyable data structure.
5462 (bfd_som_set_subsection_attributes): Likewise.
5463 (som_is_space, som_is_subspace, som_is_container): New functions.
5464 Use these instead of directly accessing private data.
5465 (som_prep_headers): Allocate space and subspace headers here.
5466 Fill in some fields in the space/subspace headers from the
5468 (som_bfd_copy_private_section_data): Only copy the stuff
5469 that we really need to make objcopy and strip work. Allocate
5470 the copy_data structure for the output bfd before copying.
5472 * som.h (struct som_exec_data): New structure to hold exec
5473 info that must be preserved when running objcopy/strip.
5474 (struct somdata): Add new "exec_data" field and accessor
5475 macro. Add some comments on how the various fields are used.
5476 (som_section_data_struct): Make is_space and is_subspace bitfields.
5477 Delete unused subspace_index. All references now use the
5478 target_index field within the section structure itself.
5480 * som.c (make_unique_section): Delete unused declaration.
5481 (som_bfd_copy_private_bfd_data): New function.
5482 (som_object_setup): Allocate space for and save exec information
5483 that needs to be copied during objcopy/strip.
5484 (som_mkobject): Do not allocate space for a file header here.
5485 It is not used when only reading SOM objects.
5486 (som_prep_headers): Allocate space for and attach a file header
5487 to the output bfd. For executables, use the saved system_id
5488 value rather than trying to guess the right value. Do not abort
5489 wwhen setting file_hdr->entry* for executables.
5490 (som_begin_writing): For executables, set the exec_entry and
5492 (som_copy_private_backend_section_data): Always return a value.
5494 * libhppa.h (PA_PAGESIZE): Define.
5496 * som.c (SOM_ALIGN): Define.
5497 (som_begin_writing): If writing an executable, initialize all
5498 fields in the exec header to zero. Update fields in the exec
5499 header as sizes of loadable subspaces are computed. Carefully
5500 preserve alignments when building executables. Actually write the
5501 exec after all the fields are filled in.
5503 * Better long-filename handling. Reads SOM ABI compliant extended
5504 names, but doesn't quite write compliant extended names yet.
5505 * som.c (som_slurp_extended_name_table): Delete function. The
5506 generic code will handle things correctly.
5507 (som_slurp_armap): Seek to the beginning of the next member.
5508 (normalize): New function.
5509 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5510 name table into account when computing the file offsets in the
5511 SOM dictionary. Make sure to align to an even boundary.
5512 (som_write_armap): Initialize the checksum to zero.
5513 (ar_maxchars): Fix. Opps.
5515 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5517 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5518 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5520 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5522 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5523 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5524 * bfd-in2.h: Regenerated.
5526 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5527 this was also named trad_unix_bfd_copy_private_bfd_data.
5529 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5531 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5532 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5533 returns NULL, it is not an error. It's possible that some of
5534 these checks are not necessary (because the size can never be
5535 zero), but putting in the checks is the conservative thing to do
5536 in light of the fact that some of these malloc calls replaced
5537 unchecked alloca calls, in which a zero argument would work fine.
5539 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5541 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5542 duplicate definition.
5543 (osf_core_bfd_is_local_label): Define.
5545 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5546 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5547 failure indication, it merely means there are no relocs.
5549 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5550 after NAME, since SunOS /bin/cc can't handle it.
5552 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5554 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5555 From sukes@glue.umd.edu (Tasuki Hirata).
5557 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5559 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5560 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5561 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5563 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5565 * som.c (som_prep_for_fixups): Detect section symbols based
5566 on either the lack of private data or the symbol flags. Do not
5567 munge section symbol names anymore -- they no longer confuse GDB.
5568 (som_begin_writing): Leave space for an exec header if writing
5570 (som_slurp_symbol_table): Recognize both forms of section symbol
5571 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5572 section symbols to be the name of the section they represent.
5573 Debugging symbols begin with "L$0\001", not just "L$".
5575 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5577 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5579 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5580 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5581 and bfd_is_local_label.
5583 * targets.c: Add new entries to the bfd_target structure.
5585 * bfd.c (bfd_copy_private_bfd_data): New definition.
5587 * section.c (bfd_copy_private_section_data): New definition.
5589 * syms.c (bfd_is_local_label): New definition.
5591 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5593 * libbfd.c (bfd_generic_is_local_label): New function.
5595 * *-core.c: Provide default definitions for new functions in
5596 the target vector which all point to bfd_false.
5598 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5599 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5600 Default new vectors for copying private backend data to bfd_true.
5601 Default new vector for determining if a symbol is a local label
5602 to bfd_generic_is_local_label.
5604 * som.c (som_bfd_copy_private_section_data): New function.
5605 (som_bfd_is_local_label): New function.
5606 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5608 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5610 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5612 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5614 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5617 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5618 Indent some of them to GNU standards.
5620 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5621 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5622 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5623 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5624 Update copyright years.
5626 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5628 * som.c (som_prep_for_fixups): A relocation involving the section
5629 symbol for the *ABS* section is really a relocation involving
5631 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5632 undefined symbols. Correctly distinguish between debugger symbols
5633 and section symbols.
5635 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5636 for spaces and subspaces.
5638 * som.c (som_bfd_count_ar_symbols): Fix typo.
5640 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5641 HAS_RELOC based on the object's magic number.
5642 (make_unique_section): Delete function. BFD and its users are
5643 prepared to handle multiple sections with the same name.
5644 (setup_sections): Allocate space on the BFD's obstack to hold
5645 section names. Use bfd_make_setion_anyway rather than the
5646 obsolete make_unique_section.
5647 (som_prep_headers): Choose the correct SOM magic number based
5649 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5651 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5653 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5654 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5655 * Makefile.in, configure.in: Corresponding changes.

5659 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5661 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5663 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5664 is always located at the start of the data section to allow
5665 recovery of the dynamic info from a stripped executable.
5666 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5669 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5671 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5672 cruft (like the #pragma alloca for AIX).
5673 In addition to that problem, the C alloca calls xmalloc, which
5674 means checking for being out of memory can't work right. The
5675 following changes remove all uses of alloca from BFD.
5676 * hosts/solaris2.h: Remove alloca cruft.

6026 bother processing them.
6027 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6730 The sparc (and possibly other?) NLM format requires a different
6731 way to write exports, so add a write_export field to the backend
6732 data (and set it to NULL for everything but the sparc).

6971 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

6976 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6977 different, so there is no point to providing a generic one.
6978 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
6979 in the backend accessor macros; that should no longer be possible.
