1677 an empty .plt section.
1678 (elf32_sparc_relocate_section): For a GOT reloc against a global
1679 symbol when no dynamic object was seen, initialize the contents of
1680 the .got section. For a GOT reloc against a local symbol, only

5225 counting relocs. Set SEC_RELOC flag for any section which has
5228 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
5230 * linker.c (_bfd_generic_link_add_symbols): Just call
5231 generic_link_add_symbols.
5232 (_bfd_generic_link_add_symbols_collect): New function, like
5233 _bfd_generic_link_add_symbols but also collect constructors and
5234 destructors by name as collect2 does.
5235 (generic_link_add_symbols): New function, like old
5236 _bfd_generic_link_add_symbols but with collect argument.
5237 (generic_link_add_object_symbols): Take collect argument.
5238 (generic_link_check_archive_element_no_collect): New function.

5244 * libbfd-in.h (_bfd_generic_link_add_symbols_collect): Declare.
5245 * libbfd.h: Rebuilt.
5247 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5249 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
5250 for first character in an extended name.
5251 (_bfd_write_archive_contents): If ar_padchar == '/', then use
5252 "//" as the name of the special archive member holding the
5253 extended name table.
5255 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5257 Support for link_order types which generate relocs in order to
5258 support -Ur in the linker.
5259 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5260 from call to _bfd_generic_link_add_one_symbol.
5261 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5262 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5263 instead of bitsize to add_to_set call back.
5264 (_bfd_generic_final_link): Account for link_order relocs when
5265 allocating space for relocations. Handle them in link_order loop.
5266 (_bfd_generic_reloc_link_order): New function.
5267 (_bfd_default_link_order): If a reloc_link_order is seen here,
5269 (_bfd_count_link_order_relocs): New function.
5270 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5271 argument from declaration.
5272 (_bfd_generic_reloc_link_order): Declare.
5273 (_bfd_count_link_order_relocs): Declare.
5274 * libbfd.h: Rebuilt.
5275 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5276 call to _bfd_generic_link_add_one_symbol.
5277 (NAME(aout,final_link)): Account for link_order relocs when

5280 (aout_link_reloc_link_order): New function.
5281 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
5282 call to _bfd_generic_link_add_one_symbol.
5283 (ecoff_bfd_final_link): Account for link_order relocs when
5284 allocating space for relocations. Handle them in link_order loop.
5285 (ecoff_link_write_external): Set the storage class of a defined
5286 linker created symbol based on the section it is in. Correct
5287 bfd_link_hash_weak case to use .sc rather than .st.
5288 (ecoff_reloc_link_order): New function.
5289 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5291 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5293 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5296 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5297 bfd_zmalloc. Free a pointer, not a union.
5298 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5300 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5302 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5304 * som.c (bfd_section_from_som_symbol): Only to do the value
5305 comparison for function symbols within executables.
5307 * som.c (bfd_section_from_som_symbol): Renamed from
5308 som_section_from_subspace_index. Pass in a native SOM symbol.
5309 For executables, iterate through the sections to find out
5310 which contains the symbol's address rather than using the
5311 symbol_info field. (symbol_info has a different meaning for
5312 dynamicly linked executables.)
5314 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5317 * som.c (som_begin_writing): Fix braino (one call to align
5318 space/subspace data was done unconditionally rather than
5319 just for executables.)
5321 * som.c (som_begin_writing): Align text in all executables to
5322 make HPUX kernel happy. Fixes strip/objcopy for shared
5325 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5327 * som.c (som_begin_writing): Account for alignment needs of
5328 subspaces too when writing executables. Never request a negative
5329 bss size. Fixes some problems with demand paged executables,
5330 still having problems with pure executables and shared executables.
5332 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5334 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5335 bfd_zalloc for rawptr, because later on we may call free, not
5338 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5339 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5340 * cisco-core.c: New file.
5341 * Makefile.in: Change accordingly.
5342 * configure.in: Recognize cisco_core_vec.
5343 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5344 * targets.c: Add cisco_core_vec.
5345 * bfd-in2.h: Rebuilt.
5347 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5349 * som.h (som_copyable_section_data_struct): New structure
5350 containing all the private section information which needs
5351 to be copied from input section to output section during
5353 (som_section_data_struct): Remove several fields now in
5354 som_copyable_section_data_struct. Make the space and
5355 subspace dictionaries be pointers (to save space when
5356 only reading objects).
5358 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5359 some references changed. Allocate a copyable data stucture if
5360 none exists. Store info into the copyable data structure.
5361 (bfd_som_set_subsection_attributes): Likewise.
5362 (som_is_space, som_is_subspace, som_is_container): New functions.
5363 Use these instead of directly accessing private data.
5364 (som_prep_headers): Allocate space and subspace headers here.
5365 Fill in some fields in the space/subspace headers from the
5367 (som_bfd_copy_private_section_data): Only copy the stuff
5368 that we really need to make objcopy and strip work. Allocate
5369 the copy_data structure for the output bfd before copying.
5371 * som.h (struct som_exec_data): New structure to hold exec
5372 info that must be preserved when running objcopy/strip.
5373 (struct somdata): Add new "exec_data" field and accessor
5374 macro. Add some comments on how the various fields are used.
5375 (som_section_data_struct): Make is_space and is_subspace bitfields.
5376 Delete unused subspace_index. All references now use the
5377 target_index field within the section structure itself.
5379 * som.c (make_unique_section): Delete unused declaration.
5380 (som_bfd_copy_private_bfd_data): New function.
5381 (som_object_setup): Allocate space for and save exec information
5382 that needs to be copied during objcopy/strip.
5383 (som_mkobject): Do not allocate space for a file header here.
5384 It is not used when only reading SOM objects.
5385 (som_prep_headers): Allocate space for and attach a file header
5386 to the output bfd. For executables, use the saved system_id
5387 value rather than trying to guess the right value. Do not abort
5388 wwhen setting file_hdr->entry* for executables.
5389 (som_begin_writing): For executables, set the exec_entry and
5391 (som_copy_private_backend_section_data): Always return a value.
5393 * libhppa.h (PA_PAGESIZE): Define.
5395 * som.c (SOM_ALIGN): Define.
5396 (som_begin_writing): If writing an executable, initialize all
5397 fields in the exec header to zero. Update fields in the exec
5398 header as sizes of loadable subspaces are computed. Carefully
5399 preserve alignments when building executables. Actually write the
5400 exec after all the fields are filled in.
5402 * Better long-filename handling. Reads SOM ABI compliant extended
5403 names, but doesn't quite write compliant extended names yet.
5404 * som.c (som_slurp_extended_name_table): Delete function. The
5405 generic code will handle things correctly.
5406 (som_slurp_armap): Seek to the beginning of the next member.
5407 (normalize): New function.
5408 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5409 name table into account when computing the file offsets in the
5410 SOM dictionary. Make sure to align to an even boundary.
5411 (som_write_armap): Initialize the checksum to zero.
5412 (ar_maxchars): Fix. Opps.
5414 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5416 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5417 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5419 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5421 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5422 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5423 * bfd-in2.h: Regenerated.
5425 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5426 this was also named trad_unix_bfd_copy_private_bfd_data.
5428 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5430 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5431 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5432 returns NULL, it is not an error. It's possible that some of
5433 these checks are not necessary (because the size can never be
5434 zero), but putting in the checks is the conservative thing to do
5435 in light of the fact that some of these malloc calls replaced
5436 unchecked alloca calls, in which a zero argument would work fine.
5438 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5440 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5441 duplicate definition.
5442 (osf_core_bfd_is_local_label): Define.
5444 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5445 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5446 failure indication, it merely means there are no relocs.
5448 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5449 after NAME, since SunOS /bin/cc can't handle it.
5451 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5453 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5454 From sukes@glue.umd.edu (Tasuki Hirata).
5456 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5458 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5459 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5460 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5462 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5464 * som.c (som_prep_for_fixups): Detect section symbols based
5465 on either the lack of private data or the symbol flags. Do not
5466 munge section symbol names anymore -- they no longer confuse GDB.
5467 (som_begin_writing): Leave space for an exec header if writing
5469 (som_slurp_symbol_table): Recognize both forms of section symbol
5470 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5471 section symbols to be the name of the section they represent.
5472 Debugging symbols begin with "L$0\001", not just "L$".
5474 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5476 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5478 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5479 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5480 and bfd_is_local_label.
5482 * targets.c: Add new entries to the bfd_target structure.
5484 * bfd.c (bfd_copy_private_bfd_data): New definition.
5486 * section.c (bfd_copy_private_section_data): New definition.
5488 * syms.c (bfd_is_local_label): New definition.
5490 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5492 * libbfd.c (bfd_generic_is_local_label): New function.
5494 * *-core.c: Provide default definitions for new functions in
5495 the target vector which all point to bfd_false.
5497 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5498 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5499 Default new vectors for copying private backend data to bfd_true.
5500 Default new vector for determining if a symbol is a local label
5501 to bfd_generic_is_local_label.
5503 * som.c (som_bfd_copy_private_section_data): New function.
5504 (som_bfd_is_local_label): New function.
5505 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5507 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5509 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5511 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5513 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5516 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5517 Indent some of them to GNU standards.
5519 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5520 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5521 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5522 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5523 Update copyright years.
5525 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5527 * som.c (som_prep_for_fixups): A relocation involving the section
5528 symbol for the *ABS* section is really a relocation involving
5530 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5531 undefined symbols. Correctly distinguish between debugger symbols
5532 and section symbols.
5534 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5535 for spaces and subspaces.
5537 * som.c (som_bfd_count_ar_symbols): Fix typo.
5539 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5540 HAS_RELOC based on the object's magic number.
5541 (make_unique_section): Delete function. BFD and its users are
5542 prepared to handle multiple sections with the same name.
5543 (setup_sections): Allocate space on the BFD's obstack to hold
5544 section names. Use bfd_make_setion_anyway rather than the
5545 obsolete make_unique_section.
5546 (som_prep_headers): Choose the correct SOM magic number based
5548 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5550 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5552 * elf32-ppc.c: Renamed from elf32-powerpc.c.

5562 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5563 is always located at the start of the data section to allow
5564 recovery of the dynamic info from a stripped executable.
5565 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5568 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5570 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5571 cruft (like the #pragma alloca for AIX).
5572 In addition to that problem, the C alloca calls xmalloc, which
5573 means checking for being out of memory can't work right. The
5574 following changes remove all uses of alloca from BFD.
5575 * hosts/solaris2.h: Remove alloca cruft.
5576 * som.c: Replace alloca with a fixed size auto array.

5586 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5589 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5591 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5592 Elf*_Off typedefs by their expansion, the typedefs have been
5593 removed from include/elf/internal.h.
5594 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5595 SHT_PROGBITS section.
5597 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5599 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5603 * configure.host: Recognize i[34]86-sequent-*.
5605 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5606 return from bfd_seek indicates an error.
5607 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5608 TRAD_CORE_STACK_OFFSET.
5609 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5610 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5612 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5614 * som.[ch]: Do not include libhppa.h in som.c, instead include
5617 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5618 include it in elf32-hppa.h.
5620 * som.c (log2): Return -1 on error rather than aborting.
5621 (setup_sections): Bubble up an error from log2.
5623 * Changes to make HP C compiler happy in both traditional
5625 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5627 (bfd_som_set_section_attributes): Use unsigned int rather than
5628 unsigned char to avoid GNU-C extensions.
5629 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5630 or failure rather than aborting on failure.
5632 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5634 (bfd_som_attach_aux_hdr): Add prototype.
5635 (hppa_som-gen_reloc_type): Likewise.
5637 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5638 (hppa_look_for_stubs_in_section): Do not return false on failure
5639 until rest of code is ready to handle it. Abort for now.
5641 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5643 * bfd-in2.h: Rebuilt.
5645 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

5663 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5664 action in case where caller specified no argument relocation.
5665 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5666 right in the original relocation and the stub's relocation.
5668 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5669 unused symbols argument.
5671 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5672 than asymbol * for original target symbol. All callers changed.
5673 Set reloc->sym_ptr_ptr appropriately.
5674 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5675 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5676 argument. Use the output symbols when canonicalizing the relocs,

5700 linker stubs into a single function (so they can easily share a

5749 COMPLEX relocation support (it's never used anyway).
5750 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

5925 bother processing them.
5926 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6630 way to write exports, so add a write_export field to the backend
6631 data (and set it to NULL for everything but the sparc).

7890 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
7892 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
7893 Handle symbol number of zero.
7895 * reloc.c (enum bfd_reloc_code_real): Added
7896 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
7897 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
7898 * bfd-in2.h: Rebuilt.
7899 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
7900 BFD_RELOC_MIPS_LITERAL.
7901 * elf32-mips.c (mips_reloc_map): Handle new relocs.
7902 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
7905 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
7906 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
7907 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
7908 MY_bfd_seclet_link): Define.
7909 (MY_bfd_reloc_type_lookup): Rename from
7910 MY_reloc_howto_type_lookup.
7911 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
7912 (MY(vec)): Use JUMP_TABLE rather than listing functions.
7913 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
7914 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
7915 terms of MY, because that causes a recusive invocation of CAT when
7916 expanded within JUMP_TABLE, and ANSI compilers don't expand
7918 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
7919 MY_reloc_howto_type_lookup, and don't define in terms of MY.
7920 (MY_canonicalize_reloc): Don't define in terms of MY.
7921 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
7922 than listing functions.
