967 reloc, for a global symbol or when generating a shared object.
968 Set the alignment of the .rela.got section to 2. For a

973 objects were seen, never create a PLT entry. Initialize the size
975 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
976 seen, skip most of this function, and force the size of the
977 .rela.got section to zero. Strip empty reloc sections, and strip
978 an empty .plt section.
979 (elf32_sparc_relocate_section): For a GOT reloc against a global
980 symbol when no dynamic object was seen, initialize the contents of
981 the .got section. For a GOT reloc against a local symbol, only
982 create a R_SPARC_RELATIVE reloc when generating a shared object.
983 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
984 create a PLT entry as a R_SPARC_WDISP30 reloc.
985 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
986 dynamic entries and the PLT if we saw a dynamic object.

4371 in executables left by the HP linker. Does not rely on subspace
4372 alignments as subspaces are *NOT* guaranteed to be properly

4424 from undefined to section. Change handling of PC relative relocs:
4425 if against a section, they are correct in the object file, if
4426 against an external symbol they are pcrel_offset.
4427 (mips_relax_section): New function.
4428 (mips_relax_pcrel16): New function.

4522 link_order loop. Use _bfd_generic_link_add_symbols_collect for
4523 add_symbls entry point.
4525 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4526 counting relocs. Set SEC_RELOC flag for any section which has

4554 extended name table.
4556 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4558 Support for link_order types which generate relocs in order to
4559 support -Ur in the linker.
4560 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4561 from call to _bfd_generic_link_add_one_symbol.
4562 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4563 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4564 instead of bitsize to add_to_set call back.
4565 (_bfd_generic_final_link): Account for link_order relocs when
4566 allocating space for relocations. Handle them in link_order loop.
4567 (_bfd_generic_reloc_link_order): New function.

4585 allocating space for relocations. Handle them in link_order loop.
4586 (ecoff_link_write_external): Set the storage class of a defined
4587 linker created symbol based on the section it is in. Correct
4588 bfd_link_hash_weak case to use .sc rather than .st.
4589 (ecoff_reloc_link_order): New function.
4590 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4592 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4597 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4598 bfd_zmalloc. Free a pointer, not a union.
4599 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4601 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4603 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4605 * som.c (bfd_section_from_som_symbol): Only to do the value
4606 comparison for function symbols within executables.
4608 * som.c (bfd_section_from_som_symbol): Renamed from
4609 som_section_from_subspace_index. Pass in a native SOM symbol.
4610 For executables, iterate through the sections to find out
4611 which contains the symbol's address rather than using the
4612 symbol_info field. (symbol_info has a different meaning for
4613 dynamicly linked executables.)
4615 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4618 * som.c (som_begin_writing): Fix braino (one call to align
4619 space/subspace data was done unconditionally rather than
4620 just for executables.)
4622 * som.c (som_begin_writing): Align text in all executables to
4623 make HPUX kernel happy. Fixes strip/objcopy for shared
4626 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4628 * som.c (som_begin_writing): Account for alignment needs of
4629 subspaces too when writing executables. Never request a negative
4630 bss size. Fixes some problems with demand paged executables,
4631 still having problems with pure executables and shared executables.
4633 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4635 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4636 bfd_zalloc for rawptr, because later on we may call free, not
4639 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4640 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

4643 * configure.in: Recognize cisco_core_vec.
4644 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4645 * targets.c: Add cisco_core_vec.

4648 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4650 * som.h (som_copyable_section_data_struct): New structure
4651 containing all the private section information which needs
4652 to be copied from input section to output section during
4654 (som_section_data_struct): Remove several fields now in
4655 som_copyable_section_data_struct. Make the space and
4656 subspace dictionaries be pointers (to save space when
4657 only reading objects).
4659 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4660 some references changed. Allocate a copyable data stucture if
4661 none exists. Store info into the copyable data structure.
4662 (bfd_som_set_subsection_attributes): Likewise.
4663 (som_is_space, som_is_subspace, som_is_container): New functions.
4664 Use these instead of directly accessing private data.
4665 (som_prep_headers): Allocate space and subspace headers here.
4666 Fill in some fields in the space/subspace headers from the
4668 (som_bfd_copy_private_section_data): Only copy the stuff
4669 that we really need to make objcopy and strip work. Allocate
4670 the copy_data structure for the output bfd before copying.
4672 * som.h (struct som_exec_data): New structure to hold exec
4673 info that must be preserved when running objcopy/strip.
4674 (struct somdata): Add new "exec_data" field and accessor
4675 macro. Add some comments on how the various fields are used.
4676 (som_section_data_struct): Make is_space and is_subspace bitfields.
4677 Delete unused subspace_index. All references now use the
4678 target_index field within the section structure itself.
4680 * som.c (make_unique_section): Delete unused declaration.
4681 (som_bfd_copy_private_bfd_data): New function.
4682 (som_object_setup): Allocate space for and save exec information
4683 that needs to be copied during objcopy/strip.
4684 (som_mkobject): Do not allocate space for a file header here.
4685 It is not used when only reading SOM objects.
4686 (som_prep_headers): Allocate space for and attach a file header
4687 to the output bfd. For executables, use the saved system_id
4688 value rather than trying to guess the right value. Do not abort
4689 wwhen setting file_hdr->entry* for executables.
4690 (som_begin_writing): For executables, set the exec_entry and
4692 (som_copy_private_backend_section_data): Always return a value.
4694 * libhppa.h (PA_PAGESIZE): Define.
4696 * som.c (SOM_ALIGN): Define.
4697 (som_begin_writing): If writing an executable, initialize all
4698 fields in the exec header to zero. Update fields in the exec
4699 header as sizes of loadable subspaces are computed. Carefully
4700 preserve alignments when building executables. Actually write the
4701 exec after all the fields are filled in.
4703 * Better long-filename handling. Reads SOM ABI compliant extended
4704 names, but doesn't quite write compliant extended names yet.
4705 * som.c (som_slurp_extended_name_table): Delete function. The
4706 generic code will handle things correctly.
4707 (som_slurp_armap): Seek to the beginning of the next member.
4708 (normalize): New function.
4709 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4710 name table into account when computing the file offsets in the
4711 SOM dictionary. Make sure to align to an even boundary.
4712 (som_write_armap): Initialize the checksum to zero.
4713 (ar_maxchars): Fix. Opps.
4715 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4717 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4718 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4720 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4722 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4723 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4724 * bfd-in2.h: Regenerated.
4726 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4727 this was also named trad_unix_bfd_copy_private_bfd_data.
4729 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4731 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4732 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4733 returns NULL, it is not an error. It's possible that some of
4734 these checks are not necessary (because the size can never be
4735 zero), but putting in the checks is the conservative thing to do
4736 in light of the fact that some of these malloc calls replaced
4737 unchecked alloca calls, in which a zero argument would work fine.
4739 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4741 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4742 duplicate definition.
4743 (osf_core_bfd_is_local_label): Define.
4745 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4746 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4747 failure indication, it merely means there are no relocs.
4749 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4750 after NAME, since SunOS /bin/cc can't handle it.
4752 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4754 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4755 From sukes@glue.umd.edu (Tasuki Hirata).
4757 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4759 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4760 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4761 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

4828 * som.c (som_prep_for_fixups): A relocation involving the section
4829 symbol for the *ABS* section is really a relocation involving
4831 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4832 undefined symbols. Correctly distinguish between debugger symbols
4833 and section symbols.

4872 cruft (like the #pragma alloca for AIX).
4873 In addition to that problem, the C alloca calls xmalloc, which
4874 means checking for being out of memory can't work right. The

4924 * Changes to make HP C compiler happy in both traditional
4926 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

5714 _bfd_generic_link_write_global_symbol): Don't require that all
5715 references to a common symbol be themselves common symbols.

5760 (only testing for m68k and vax at the moment); do verify that the
5761 preprocessor didn't trash the arch name inside the string version.

5792 bfd_som_set_subsection_attributes): Change parameters from char
5793 to int. Following a prototype with an old-style function definition

5900 use get_value to get the symbol value and check for undefined
5902 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5903 undefined, look it up in the linker hash table.
5905 * aoutx.h (translate_symbol_table): The string index 0 has a

5930 The sparc (and possibly other?) NLM format requires a different
5931 way to write exports, so add a write_export field to the backend
5932 data (and set it to NULL for everything but the sparc).
