938 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.

953 symbol when no dynamic object was seen, initialize the contents of
954 the .got section. For a GOT reloc against a local symbol, only

956 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
957 create a PLT entry as a R_SPARC_WDISP30 reloc.
958 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
959 dynamic entries and the PLT if we saw a dynamic object.

4343 * som.c (som_begin_writing): New approach at dealing with holes
4344 in executables left by the HP linker. Does not rely on subspace
4345 alignments as subspaces are *NOT* guaranteed to be properly
4346 aligned in an executable (can you believe that!).
4348 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4350 * som.c (som_get_section_contents): New function. Do not try

4396 required by expansions. Set s and unset h when converting a reloc
4397 from undefined to section. Change handling of PC relative relocs:
4398 if against a section, they are correct in the object file, if
4399 against an external symbol they are pcrel_offset.
4400 (mips_relax_section): New function.
4401 (mips_relax_pcrel16): New function.

4486 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4487 reloc, used in embedded PIC code.
4488 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
4489 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

4495 link_order loop. Use _bfd_generic_link_add_symbols_collect for
4496 add_symbls entry point.
4498 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4499 counting relocs. Set SEC_RELOC flag for any section which has

4507 _bfd_generic_link_add_symbols but also collect constructors and
4508 destructors by name as collect2 does.

4527 extended name table.
4529 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4531 Support for link_order types which generate relocs in order to
4532 support -Ur in the linker.
4533 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4534 from call to _bfd_generic_link_add_one_symbol.
4535 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4536 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4537 instead of bitsize to add_to_set call back.
4538 (_bfd_generic_final_link): Account for link_order relocs when
4539 allocating space for relocations. Handle them in link_order loop.
4540 (_bfd_generic_reloc_link_order): New function.

4545 argument from declaration.
4546 (_bfd_generic_reloc_link_order): Declare.

4557 (ecoff_bfd_final_link): Account for link_order relocs when
4558 allocating space for relocations. Handle them in link_order loop.
4559 (ecoff_link_write_external): Set the storage class of a defined
4560 linker created symbol based on the section it is in. Correct
4561 bfd_link_hash_weak case to use .sc rather than .st.
4562 (ecoff_reloc_link_order): New function.
4563 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4565 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4571 bfd_zmalloc. Free a pointer, not a union.
4572 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4574 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4576 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4578 * som.c (bfd_section_from_som_symbol): Only to do the value
4579 comparison for function symbols within executables.
4581 * som.c (bfd_section_from_som_symbol): Renamed from
4582 som_section_from_subspace_index. Pass in a native SOM symbol.
4583 For executables, iterate through the sections to find out
4584 which contains the symbol's address rather than using the
4585 symbol_info field. (symbol_info has a different meaning for
4586 dynamicly linked executables.)
4588 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4591 * som.c (som_begin_writing): Fix braino (one call to align
4592 space/subspace data was done unconditionally rather than
4593 just for executables.)
4595 * som.c (som_begin_writing): Align text in all executables to
4596 make HPUX kernel happy. Fixes strip/objcopy for shared
4599 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4601 * som.c (som_begin_writing): Account for alignment needs of
4602 subspaces too when writing executables. Never request a negative
4603 bss size. Fixes some problems with demand paged executables,
4604 still having problems with pure executables and shared executables.
4606 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4608 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4609 bfd_zalloc for rawptr, because later on we may call free, not
4612 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4613 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4614 * cisco-core.c: New file.
4615 * Makefile.in: Change accordingly.
4616 * configure.in: Recognize cisco_core_vec.
4617 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4618 * targets.c: Add cisco_core_vec.
4619 * bfd-in2.h: Rebuilt.
4621 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4623 * som.h (som_copyable_section_data_struct): New structure
4624 containing all the private section information which needs
4625 to be copied from input section to output section during
4627 (som_section_data_struct): Remove several fields now in
4628 som_copyable_section_data_struct. Make the space and
4629 subspace dictionaries be pointers (to save space when
4630 only reading objects).
4632 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4633 some references changed. Allocate a copyable data stucture if
4634 none exists. Store info into the copyable data structure.
4635 (bfd_som_set_subsection_attributes): Likewise.
4636 (som_is_space, som_is_subspace, som_is_container): New functions.
4637 Use these instead of directly accessing private data.
4638 (som_prep_headers): Allocate space and subspace headers here.
4639 Fill in some fields in the space/subspace headers from the
4641 (som_bfd_copy_private_section_data): Only copy the stuff
4642 that we really need to make objcopy and strip work. Allocate
4643 the copy_data structure for the output bfd before copying.
4645 * som.h (struct som_exec_data): New structure to hold exec
4646 info that must be preserved when running objcopy/strip.
4647 (struct somdata): Add new "exec_data" field and accessor
4648 macro. Add some comments on how the various fields are used.
4649 (som_section_data_struct): Make is_space and is_subspace bitfields.
4650 Delete unused subspace_index. All references now use the
4651 target_index field within the section structure itself.
4653 * som.c (make_unique_section): Delete unused declaration.
4654 (som_bfd_copy_private_bfd_data): New function.
4655 (som_object_setup): Allocate space for and save exec information
4656 that needs to be copied during objcopy/strip.
4657 (som_mkobject): Do not allocate space for a file header here.
4658 It is not used when only reading SOM objects.
4659 (som_prep_headers): Allocate space for and attach a file header
4660 to the output bfd. For executables, use the saved system_id
4661 value rather than trying to guess the right value. Do not abort
4662 wwhen setting file_hdr->entry* for executables.
4663 (som_begin_writing): For executables, set the exec_entry and
4665 (som_copy_private_backend_section_data): Always return a value.
4667 * libhppa.h (PA_PAGESIZE): Define.
4669 * som.c (SOM_ALIGN): Define.
4670 (som_begin_writing): If writing an executable, initialize all
4671 fields in the exec header to zero. Update fields in the exec
4672 header as sizes of loadable subspaces are computed. Carefully
4673 preserve alignments when building executables. Actually write the
4674 exec after all the fields are filled in.
4676 * Better long-filename handling. Reads SOM ABI compliant extended
4677 names, but doesn't quite write compliant extended names yet.
4678 * som.c (som_slurp_extended_name_table): Delete function. The
4679 generic code will handle things correctly.
4680 (som_slurp_armap): Seek to the beginning of the next member.
4681 (normalize): New function.
4682 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4683 name table into account when computing the file offsets in the
4684 SOM dictionary. Make sure to align to an even boundary.
4685 (som_write_armap): Initialize the checksum to zero.
4686 (ar_maxchars): Fix. Opps.
4688 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4690 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4691 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4693 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4695 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4696 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4697 * bfd-in2.h: Regenerated.
4699 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4700 this was also named trad_unix_bfd_copy_private_bfd_data.
4702 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4704 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4705 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4706 returns NULL, it is not an error. It's possible that some of
4707 these checks are not necessary (because the size can never be
4708 zero), but putting in the checks is the conservative thing to do
4709 in light of the fact that some of these malloc calls replaced
4710 unchecked alloca calls, in which a zero argument would work fine.
4712 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4714 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4715 duplicate definition.
4716 (osf_core_bfd_is_local_label): Define.
4718 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4719 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4720 failure indication, it merely means there are no relocs.
4722 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4723 after NAME, since SunOS /bin/cc can't handle it.
4725 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4727 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4728 From sukes@glue.umd.edu (Tasuki Hirata).
4730 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4732 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4733 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4734 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4736 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4738 * som.c (som_prep_for_fixups): Detect section symbols based
4739 on either the lack of private data or the symbol flags. Do not
4740 munge section symbol names anymore -- they no longer confuse GDB.
4741 (som_begin_writing): Leave space for an exec header if writing
4743 (som_slurp_symbol_table): Recognize both forms of section symbol
4744 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4745 section symbols to be the name of the section they represent.
4746 Debugging symbols begin with "L$0\001", not just "L$".
4748 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4750 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4752 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4753 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4754 and bfd_is_local_label.
4756 * targets.c: Add new entries to the bfd_target structure.
4758 * bfd.c (bfd_copy_private_bfd_data): New definition.

4845 cruft (like the #pragma alloca for AIX).
4846 In addition to that problem, the C alloca calls xmalloc, which

5876 undefined, look it up in the linker hash table.
5878 * aoutx.h (translate_symbol_table): The string index 0 has a

5903 The sparc (and possibly other?) NLM format requires a different
5904 way to write exports, so add a write_export field to the backend
5905 data (and set it to NULL for everything but the sparc).
