3544 from undefined to section. Change handling of PC relative relocs:
3545 if against a section, they are correct in the object file, if
3546 against an external symbol they are pcrel_offset.

3679 support -Ur in the linker.
3680 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3681 from call to _bfd_generic_link_add_one_symbol.
3682 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3683 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3684 instead of bitsize to add_to_set call back.
3685 (_bfd_generic_final_link): Account for link_order relocs when
3686 allocating space for relocations. Handle them in link_order loop.

3726 comparison for function symbols within executables.
3728 * som.c (bfd_section_from_som_symbol): Renamed from
3729 som_section_from_subspace_index. Pass in a native SOM symbol.
3730 For executables, iterate through the sections to find out
3731 which contains the symbol's address rather than using the
3732 symbol_info field. (symbol_info has a different meaning for
3733 dynamicly linked executables.)
3735 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3738 * som.c (som_begin_writing): Fix braino (one call to align
3739 space/subspace data was done unconditionally rather than
3740 just for executables.)
3742 * som.c (som_begin_writing): Align text in all executables to
3743 make HPUX kernel happy. Fixes strip/objcopy for shared
3746 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3748 * som.c (som_begin_writing): Account for alignment needs of
3749 subspaces too when writing executables. Never request a negative
3750 bss size. Fixes some problems with demand paged executables,
3751 still having problems with pure executables and shared executables.
3753 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3755 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3756 bfd_zalloc for rawptr, because later on we may call free, not
3759 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3760 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

3770 * som.h (som_copyable_section_data_struct): New structure
3771 containing all the private section information which needs
3772 to be copied from input section to output section during
3774 (som_section_data_struct): Remove several fields now in
3775 som_copyable_section_data_struct. Make the space and
3776 subspace dictionaries be pointers (to save space when
3777 only reading objects).
3779 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3780 some references changed. Allocate a copyable data stucture if
3781 none exists. Store info into the copyable data structure.
3782 (bfd_som_set_subsection_attributes): Likewise.
3783 (som_is_space, som_is_subspace, som_is_container): New functions.
3784 Use these instead of directly accessing private data.
3785 (som_prep_headers): Allocate space and subspace headers here.
3786 Fill in some fields in the space/subspace headers from the
3788 (som_bfd_copy_private_section_data): Only copy the stuff
3789 that we really need to make objcopy and strip work. Allocate
3790 the copy_data structure for the output bfd before copying.
3792 * som.h (struct som_exec_data): New structure to hold exec
3793 info that must be preserved when running objcopy/strip.
3794 (struct somdata): Add new "exec_data" field and accessor
3795 macro. Add some comments on how the various fields are used.
3796 (som_section_data_struct): Make is_space and is_subspace bitfields.
3797 Delete unused subspace_index. All references now use the
3798 target_index field within the section structure itself.
3800 * som.c (make_unique_section): Delete unused declaration.
3801 (som_bfd_copy_private_bfd_data): New function.
3802 (som_object_setup): Allocate space for and save exec information
3803 that needs to be copied during objcopy/strip.
3804 (som_mkobject): Do not allocate space for a file header here.
3805 It is not used when only reading SOM objects.
3806 (som_prep_headers): Allocate space for and attach a file header
3807 to the output bfd. For executables, use the saved system_id
3808 value rather than trying to guess the right value. Do not abort
3809 wwhen setting file_hdr->entry* for executables.
3810 (som_begin_writing): For executables, set the exec_entry and
3812 (som_copy_private_backend_section_data): Always return a value.
3814 * libhppa.h (PA_PAGESIZE): Define.
3816 * som.c (SOM_ALIGN): Define.
3817 (som_begin_writing): If writing an executable, initialize all
3818 fields in the exec header to zero. Update fields in the exec
3819 header as sizes of loadable subspaces are computed. Carefully
3820 preserve alignments when building executables. Actually write the
3821 exec after all the fields are filled in.
3823 * Better long-filename handling. Reads SOM ABI compliant extended
3824 names, but doesn't quite write compliant extended names yet.
3825 * som.c (som_slurp_extended_name_table): Delete function. The
3826 generic code will handle things correctly.
3827 (som_slurp_armap): Seek to the beginning of the next member.
3828 (normalize): New function.
3829 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3830 name table into account when computing the file offsets in the
3831 SOM dictionary. Make sure to align to an even boundary.
3832 (som_write_armap): Initialize the checksum to zero.
3833 (ar_maxchars): Fix. Opps.
3835 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3837 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3838 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

3842 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3843 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3844 * bfd-in2.h: Regenerated.
3846 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3847 this was also named trad_unix_bfd_copy_private_bfd_data.
3849 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3851 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3852 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3853 returns NULL, it is not an error. It's possible that some of
3854 these checks are not necessary (because the size can never be
3855 zero), but putting in the checks is the conservative thing to do
3856 in light of the fact that some of these malloc calls replaced
3857 unchecked alloca calls, in which a zero argument would work fine.
3859 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3861 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3862 duplicate definition.
3863 (osf_core_bfd_is_local_label): Define.
3865 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3866 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3867 failure indication, it merely means there are no relocs.
3869 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3870 after NAME, since SunOS /bin/cc can't handle it.
3872 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3874 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3875 From sukes@glue.umd.edu (Tasuki Hirata).

3879 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3880 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3881 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3883 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3885 * som.c (som_prep_for_fixups): Detect section symbols based

3948 * som.c (som_prep_for_fixups): A relocation involving the section
3949 symbol for the *ABS* section is really a relocation involving
3951 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3952 undefined symbols. Correctly distinguish between debugger symbols
3953 and section symbols.

3956 for spaces and subspaces.
3958 * som.c (som_bfd_count_ar_symbols): Fix typo.

3992 cruft (like the #pragma alloca for AIX).
3993 In addition to that problem, the C alloca calls xmalloc, which
3994 means checking for being out of memory can't work right. The
3995 following changes remove all uses of alloca from BFD.

4038 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4039 include it in elf32-hppa.h.
4041 * som.c (log2): Return -1 on error rather than aborting.
4042 (setup_sections): Bubble up an error from log2.
4044 * Changes to make HP C compiler happy in both traditional
4046 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

4049 unsigned char to avoid GNU-C extensions.
4050 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4051 or failure rather than aborting on failure.
4053 * som.h (bfd_som_set_section_attributes): Fix prototype to match

4332 * section.c (bfd_get_section_contents): Since this function reads
4333 unrelocated contents, the section's raw size is always the one to
4334 use for bounds checking.

4343 current offset in the section plus the number of bytes of padding
4344 that will actually be retained.
4345 (b_out_relax_section): If a section contains no relocations, don't
4346 bother processing them.
4347 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4351 that reloc->addend falls between the current source offset and the
4352 raw size of the input section.

4834 _bfd_generic_link_write_global_symbol): Don't require that all
4835 references to a common symbol be themselves common symbols.

4880 (only testing for m68k and vax at the moment); do verify that the
4881 preprocessor didn't trash the arch name inside the string version.

4912 bfd_som_set_subsection_attributes): Change parameters from char
4913 to int. Following a prototype with an old-style function definition

5020 use get_value to get the symbol value and check for undefined
5022 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5023 undefined, look it up in the linker hash table.
5025 * aoutx.h (translate_symbol_table): The string index 0 has a

5050 The sparc (and possibly other?) NLM format requires a different
5051 way to write exports, so add a write_export field to the backend
5052 data (and set it to NULL for everything but the sparc).
