4327 add_symbls entry point.
4329 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4330 counting relocs. Set SEC_RELOC flag for any section which has
4333 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
4335 * linker.c (_bfd_generic_link_add_symbols): Just call
4336 generic_link_add_symbols.
4337 (_bfd_generic_link_add_symbols_collect): New function, like
4338 _bfd_generic_link_add_symbols but also collect constructors and
4339 destructors by name as collect2 does.
4340 (generic_link_add_symbols): New function, like old
4341 _bfd_generic_link_add_symbols but with collect argument.
4342 (generic_link_add_object_symbols): Take collect argument.

4350 * libbfd.h: Rebuilt.
4352 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4354 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
4355 for first character in an extended name.
4356 (_bfd_write_archive_contents): If ar_padchar == '/', then use
4357 "//" as the name of the special archive member holding the
4358 extended name table.
4360 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4362 Support for link_order types which generate relocs in order to
4363 support -Ur in the linker.
4364 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4365 from call to _bfd_generic_link_add_one_symbol.
4366 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4367 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4368 instead of bitsize to add_to_set call back.
4369 (_bfd_generic_final_link): Account for link_order relocs when
4370 allocating space for relocations. Handle them in link_order loop.
4371 (_bfd_generic_reloc_link_order): New function.
4372 (_bfd_default_link_order): If a reloc_link_order is seen here,
4374 (_bfd_count_link_order_relocs): New function.
4375 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4376 argument from declaration.
4377 (_bfd_generic_reloc_link_order): Declare.
4378 (_bfd_count_link_order_relocs): Declare.
4379 * libbfd.h: Rebuilt.
4380 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
4381 call to _bfd_generic_link_add_one_symbol.
4382 (NAME(aout,final_link)): Account for link_order relocs when

4385 (aout_link_reloc_link_order): New function.
4386 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
4387 call to _bfd_generic_link_add_one_symbol.
4388 (ecoff_bfd_final_link): Account for link_order relocs when
4389 allocating space for relocations. Handle them in link_order loop.
4390 (ecoff_link_write_external): Set the storage class of a defined
4391 linker created symbol based on the section it is in. Correct
4392 bfd_link_hash_weak case to use .sc rather than .st.
4393 (ecoff_reloc_link_order): New function.
4394 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4396 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4398 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4401 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4402 bfd_zmalloc. Free a pointer, not a union.
4403 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4405 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4407 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4409 * som.c (bfd_section_from_som_symbol): Only to do the value
4410 comparison for function symbols within executables.
4412 * som.c (bfd_section_from_som_symbol): Renamed from
4413 som_section_from_subspace_index. Pass in a native SOM symbol.
4414 For executables, iterate through the sections to find out
4415 which contains the symbol's address rather than using the
4416 symbol_info field. (symbol_info has a different meaning for
4417 dynamicly linked executables.)
4419 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4422 * som.c (som_begin_writing): Fix braino (one call to align
4423 space/subspace data was done unconditionally rather than
4424 just for executables.)
4426 * som.c (som_begin_writing): Align text in all executables to
4427 make HPUX kernel happy. Fixes strip/objcopy for shared
4430 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4432 * som.c (som_begin_writing): Account for alignment needs of
4433 subspaces too when writing executables. Never request a negative
4434 bss size. Fixes some problems with demand paged executables,
4435 still having problems with pure executables and shared executables.
4437 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4439 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4440 bfd_zalloc for rawptr, because later on we may call free, not
4443 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4444 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4445 * cisco-core.c: New file.
4446 * Makefile.in: Change accordingly.
4447 * configure.in: Recognize cisco_core_vec.
4448 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4449 * targets.c: Add cisco_core_vec.
4450 * bfd-in2.h: Rebuilt.
4452 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4454 * som.h (som_copyable_section_data_struct): New structure
4455 containing all the private section information which needs
4456 to be copied from input section to output section during
4458 (som_section_data_struct): Remove several fields now in
4459 som_copyable_section_data_struct. Make the space and
4460 subspace dictionaries be pointers (to save space when
4461 only reading objects).
4463 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4464 some references changed. Allocate a copyable data stucture if
4465 none exists. Store info into the copyable data structure.
4466 (bfd_som_set_subsection_attributes): Likewise.
4467 (som_is_space, som_is_subspace, som_is_container): New functions.
4468 Use these instead of directly accessing private data.
4469 (som_prep_headers): Allocate space and subspace headers here.
4470 Fill in some fields in the space/subspace headers from the
4472 (som_bfd_copy_private_section_data): Only copy the stuff
4473 that we really need to make objcopy and strip work. Allocate
4474 the copy_data structure for the output bfd before copying.
4476 * som.h (struct som_exec_data): New structure to hold exec
4477 info that must be preserved when running objcopy/strip.
4478 (struct somdata): Add new "exec_data" field and accessor
4479 macro. Add some comments on how the various fields are used.
4480 (som_section_data_struct): Make is_space and is_subspace bitfields.
4481 Delete unused subspace_index. All references now use the
4482 target_index field within the section structure itself.
4484 * som.c (make_unique_section): Delete unused declaration.
4485 (som_bfd_copy_private_bfd_data): New function.
4486 (som_object_setup): Allocate space for and save exec information
4487 that needs to be copied during objcopy/strip.
4488 (som_mkobject): Do not allocate space for a file header here.
4489 It is not used when only reading SOM objects.
4490 (som_prep_headers): Allocate space for and attach a file header
4491 to the output bfd. For executables, use the saved system_id
4492 value rather than trying to guess the right value. Do not abort
4493 wwhen setting file_hdr->entry* for executables.
4494 (som_begin_writing): For executables, set the exec_entry and
4496 (som_copy_private_backend_section_data): Always return a value.
4498 * libhppa.h (PA_PAGESIZE): Define.
4500 * som.c (SOM_ALIGN): Define.
4501 (som_begin_writing): If writing an executable, initialize all
4502 fields in the exec header to zero. Update fields in the exec
4503 header as sizes of loadable subspaces are computed. Carefully
4504 preserve alignments when building executables. Actually write the
4505 exec after all the fields are filled in.
4507 * Better long-filename handling. Reads SOM ABI compliant extended
4508 names, but doesn't quite write compliant extended names yet.
4509 * som.c (som_slurp_extended_name_table): Delete function. The
4510 generic code will handle things correctly.
4511 (som_slurp_armap): Seek to the beginning of the next member.
4512 (normalize): New function.
4513 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4514 name table into account when computing the file offsets in the
4515 SOM dictionary. Make sure to align to an even boundary.
4516 (som_write_armap): Initialize the checksum to zero.
4517 (ar_maxchars): Fix. Opps.
4519 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4521 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4522 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4524 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4526 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4527 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4528 * bfd-in2.h: Regenerated.
4530 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4531 this was also named trad_unix_bfd_copy_private_bfd_data.
4533 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4535 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4536 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4537 returns NULL, it is not an error. It's possible that some of
4538 these checks are not necessary (because the size can never be
4539 zero), but putting in the checks is the conservative thing to do
4540 in light of the fact that some of these malloc calls replaced
4541 unchecked alloca calls, in which a zero argument would work fine.
4543 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4545 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4546 duplicate definition.
4547 (osf_core_bfd_is_local_label): Define.
4549 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4550 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4551 failure indication, it merely means there are no relocs.
4553 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4554 after NAME, since SunOS /bin/cc can't handle it.
4556 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4558 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4559 From sukes@glue.umd.edu (Tasuki Hirata).
4561 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4563 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4564 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4565 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4567 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4569 * som.c (som_prep_for_fixups): Detect section symbols based
4570 on either the lack of private data or the symbol flags. Do not
4571 munge section symbol names anymore -- they no longer confuse GDB.
4572 (som_begin_writing): Leave space for an exec header if writing
4574 (som_slurp_symbol_table): Recognize both forms of section symbol
4575 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4576 section symbols to be the name of the section they represent.
4577 Debugging symbols begin with "L$0\001", not just "L$".
4579 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4581 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4583 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4584 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4585 and bfd_is_local_label.
4587 * targets.c: Add new entries to the bfd_target structure.
4589 * bfd.c (bfd_copy_private_bfd_data): New definition.
4591 * section.c (bfd_copy_private_section_data): New definition.
4593 * syms.c (bfd_is_local_label): New definition.
4595 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4597 * libbfd.c (bfd_generic_is_local_label): New function.
4599 * *-core.c: Provide default definitions for new functions in
4600 the target vector which all point to bfd_false.
4602 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4603 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4604 Default new vectors for copying private backend data to bfd_true.
4605 Default new vector for determining if a symbol is a local label
4606 to bfd_generic_is_local_label.
4608 * som.c (som_bfd_copy_private_section_data): New function.
4609 (som_bfd_is_local_label): New function.
4610 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4612 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4614 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4616 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4618 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4621 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4622 Indent some of them to GNU standards.
4624 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4625 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4626 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4627 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4628 Update copyright years.
4630 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4632 * som.c (som_prep_for_fixups): A relocation involving the section
4633 symbol for the *ABS* section is really a relocation involving
4635 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4636 undefined symbols. Correctly distinguish between debugger symbols
4637 and section symbols.
4639 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4640 for spaces and subspaces.
4642 * som.c (som_bfd_count_ar_symbols): Fix typo.
4644 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4645 HAS_RELOC based on the object's magic number.
4646 (make_unique_section): Delete function. BFD and its users are
4647 prepared to handle multiple sections with the same name.
4648 (setup_sections): Allocate space on the BFD's obstack to hold
4649 section names. Use bfd_make_setion_anyway rather than the
4650 obsolete make_unique_section.
4651 (som_prep_headers): Choose the correct SOM magic number based
4653 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4655 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4657 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4667 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4668 is always located at the start of the data section to allow
4669 recovery of the dynamic info from a stripped executable.
4670 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4673 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4675 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4676 cruft (like the #pragma alloca for AIX).
4677 In addition to that problem, the C alloca calls xmalloc, which
4678 means checking for being out of memory can't work right. The
4679 following changes remove all uses of alloca from BFD.
4680 * hosts/solaris2.h: Remove alloca cruft.
4681 * som.c: Replace alloca with a fixed size auto array.

4691 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4694 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4696 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4697 Elf*_Off typedefs by their expansion, the typedefs have been
4698 removed from include/elf/internal.h.
4699 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4700 SHT_PROGBITS section.
4702 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4704 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4708 * configure.host: Recognize i[34]86-sequent-*.
4710 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4711 return from bfd_seek indicates an error.
4712 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4713 TRAD_CORE_STACK_OFFSET.
4714 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4715 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4717 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4719 * som.[ch]: Do not include libhppa.h in som.c, instead include
4722 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4723 include it in elf32-hppa.h.
4725 * som.c (log2): Return -1 on error rather than aborting.
4726 (setup_sections): Bubble up an error from log2.
4728 * Changes to make HP C compiler happy in both traditional
4730 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4732 (bfd_som_set_section_attributes): Use unsigned int rather than
4733 unsigned char to avoid GNU-C extensions.
4734 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4735 or failure rather than aborting on failure.
4737 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4739 (bfd_som_attach_aux_hdr): Add prototype.
4740 (hppa_som-gen_reloc_type): Likewise.
4742 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4743 (hppa_look_for_stubs_in_section): Do not return false on failure
4744 until rest of code is ready to handle it. Abort for now.
4746 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4748 * bfd-in2.h: Rebuilt.
4750 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

4768 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4769 action in case where caller specified no argument relocation.
4770 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4771 right in the original relocation and the stub's relocation.
4773 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4774 unused symbols argument.
4776 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4777 than asymbol * for original target symbol. All callers changed.
4778 Set reloc->sym_ptr_ptr appropriately.
4779 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4780 (hppa_elf_look_for_stubs_in_section): No longer need symbols

4804 #defines for lots of things. Merge two functions which build
4805 linker stubs into a single function (so they can easily share a
4806 ton of common code).

5029 (b_out_relax_section): If a section contains no relocations, don't
5030 bother processing them.
5031 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5735 way to write exports, so add a write_export field to the backend
5736 data (and set it to NULL for everything but the sparc).

6988 * libbfd.h (artdata): Use long, not time_t for portability, at
6991 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
6993 * config.bfd: Use bigmips for mips*-*-bsd*.
6995 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6997 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
6998 Handle symbol number of zero.
7000 * reloc.c (enum bfd_reloc_code_real): Added
7001 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
7002 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
7003 * bfd-in2.h: Rebuilt.
7004 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
7005 BFD_RELOC_MIPS_LITERAL.
7006 * elf32-mips.c (mips_reloc_map): Handle new relocs.
7007 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
7010 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
7011 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
7012 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
7013 MY_bfd_seclet_link): Define.
7014 (MY_bfd_reloc_type_lookup): Rename from
7015 MY_reloc_howto_type_lookup.
7016 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
7017 (MY(vec)): Use JUMP_TABLE rather than listing functions.
7018 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
7019 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
7020 terms of MY, because that causes a recusive invocation of CAT when
7021 expanded within JUMP_TABLE, and ANSI compilers don't expand
7023 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
7024 MY_reloc_howto_type_lookup, and don't define in terms of MY.
7025 (MY_canonicalize_reloc): Don't define in terms of MY.
7026 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
7027 than listing functions.
