1874 dynamic_sections_created field, not dynobj field. Don't bother to
1876 (elf_link_create_dynamic_sections): If dynamic sections were
1877 already created, don't do anything. If dynobj is already set, use
1878 it; otherwise, set it to the bfd argument. Don't initialize

1936 an empty .plt section.
1937 (elf32_sparc_relocate_section): For a GOT reloc against a global
1938 symbol when no dynamic object was seen, initialize the contents of
1939 the .got section. For a GOT reloc against a local symbol, only
1940 create a R_SPARC_RELATIVE reloc when generating a shared object.
1941 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1942 create a PLT entry as a R_SPARC_WDISP30 reloc.
1943 (elf32_sparc_finish_dynamic_sections): Only fiddle with the

5569 which contains the symbol's address rather than using the
5570 symbol_info field. (symbol_info has a different meaning for
5571 dynamicly linked executables.)
5573 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5576 * som.c (som_begin_writing): Fix braino (one call to align

5613 som_copyable_section_data_struct. Make the space and
5614 subspace dictionaries be pointers (to save space when
5615 only reading objects).
5617 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5618 some references changed. Allocate a copyable data stucture if
5619 none exists. Store info into the copyable data structure.

5621 (som_is_space, som_is_subspace, som_is_container): New functions.
5622 Use these instead of directly accessing private data.
5623 (som_prep_headers): Allocate space and subspace headers here.
5624 Fill in some fields in the space/subspace headers from the
5626 (som_bfd_copy_private_section_data): Only copy the stuff
5627 that we really need to make objcopy and strip work. Allocate
5628 the copy_data structure for the output bfd before copying.
5630 * som.h (struct som_exec_data): New structure to hold exec
5631 info that must be preserved when running objcopy/strip.

5633 macro. Add some comments on how the various fields are used.
5634 (som_section_data_struct): Make is_space and is_subspace bitfields.

5643 It is not used when only reading SOM objects.
5644 (som_prep_headers): Allocate space for and attach a file header
5645 to the output bfd. For executables, use the saved system_id
5646 value rather than trying to guess the right value. Do not abort
5647 wwhen setting file_hdr->entry* for executables.
5648 (som_begin_writing): For executables, set the exec_entry and
5650 (som_copy_private_backend_section_data): Always return a value.
5652 * libhppa.h (PA_PAGESIZE): Define.

5655 (som_begin_writing): If writing an executable, initialize all
5656 fields in the exec header to zero. Update fields in the exec
5657 header as sizes of loadable subspaces are computed. Carefully
5658 preserve alignments when building executables. Actually write the
5659 exec after all the fields are filled in.
5661 * Better long-filename handling. Reads SOM ABI compliant extended
5662 names, but doesn't quite write compliant extended names yet.
5663 * som.c (som_slurp_extended_name_table): Delete function. The
5664 generic code will handle things correctly.
5665 (som_slurp_armap): Seek to the beginning of the next member.
5666 (normalize): New function.
5667 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5668 name table into account when computing the file offsets in the
5669 SOM dictionary. Make sure to align to an even boundary.
5670 (som_write_armap): Initialize the checksum to zero.
5671 (ar_maxchars): Fix. Opps.

5689 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5690 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5691 returns NULL, it is not an error. It's possible that some of
5692 these checks are not necessary (because the size can never be
5693 zero), but putting in the checks is the conservative thing to do
5694 in light of the fact that some of these malloc calls replaced
5695 unchecked alloca calls, in which a zero argument would work fine.
5697 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5699 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5700 duplicate definition.

5703 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5704 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5705 failure indication, it merely means there are no relocs.
5707 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5708 after NAME, since SunOS /bin/cc can't handle it.
5710 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5712 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5713 From sukes@glue.umd.edu (Tasuki Hirata).
5715 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5717 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5718 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5719 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5721 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5723 * som.c (som_prep_for_fixups): Detect section symbols based
5724 on either the lack of private data or the symbol flags. Do not
5725 munge section symbol names anymore -- they no longer confuse GDB.
5726 (som_begin_writing): Leave space for an exec header if writing
5728 (som_slurp_symbol_table): Recognize both forms of section symbol
5729 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5730 section symbols to be the name of the section they represent.
5731 Debugging symbols begin with "L$0\001", not just "L$".

5757 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5758 Default new vectors for copying private backend data to bfd_true.

5760 to bfd_generic_is_local_label.
5762 * som.c (som_bfd_copy_private_section_data): New function.
5763 (som_bfd_is_local_label): New function.

5768 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5770 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5772 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5775 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5776 Indent some of them to GNU standards.
5778 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5779 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

5781 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5782 Update copyright years.
5784 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5786 * som.c (som_prep_for_fixups): A relocation involving the section
5787 symbol for the *ABS* section is really a relocation involving
5789 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5790 undefined symbols. Correctly distinguish between debugger symbols
5791 and section symbols.
5793 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5794 for spaces and subspaces.
5796 * som.c (som_bfd_count_ar_symbols): Fix typo.
5798 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5799 HAS_RELOC based on the object's magic number.
5800 (make_unique_section): Delete function. BFD and its users are
5801 prepared to handle multiple sections with the same name.
5802 (setup_sections): Allocate space on the BFD's obstack to hold
5803 section names. Use bfd_make_setion_anyway rather than the
5804 obsolete make_unique_section.
5805 (som_prep_headers): Choose the correct SOM magic number based
5807 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5827 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5829 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5830 cruft (like the #pragma alloca for AIX).
5831 In addition to that problem, the C alloca calls xmalloc, which
5832 means checking for being out of memory can't work right. The
5833 following changes remove all uses of alloca from BFD.
5834 * hosts/solaris2.h: Remove alloca cruft.
5835 * som.c: Replace alloca with a fixed size auto array.

5850 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5851 Elf*_Off typedefs by their expansion, the typedefs have been
5852 removed from include/elf/internal.h.
5853 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5854 SHT_PROGBITS section.

5873 * som.[ch]: Do not include libhppa.h in som.c, instead include
5876 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5877 include it in elf32-hppa.h.
5879 * som.c (log2): Return -1 on error rather than aborting.
5880 (setup_sections): Bubble up an error from log2.
5882 * Changes to make HP C compiler happy in both traditional
5884 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5886 (bfd_som_set_section_attributes): Use unsigned int rather than
5887 unsigned char to avoid GNU-C extensions.
5888 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5889 or failure rather than aborting on failure.
5891 * som.h (bfd_som_set_section_attributes): Fix prototype to match

5934 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5935 argument. Use the output symbols when canonicalizing the relocs,
5936 creating them if necessary.
5938 * linker.c (_bfd_generic_link_output_symbols): Do not
5939 rebuild/clobber the output symbols if they already exist.

5958 #defines for lots of things. Merge two functions which build
5959 linker stubs into a single function (so they can easily share a
5960 ton of common code).

6008 COMPLEX relocation support (it's never used anyway).
6009 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

6183 (b_out_relax_section): If a section contains no relocations, don't
6184 bother processing them.
6185 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6189 that reloc->addend falls between the current source offset and the
6190 raw size of the input section.

6213 * Finish basic read-write support for SOM archive libraries. Bugs
6214 surely remain as this hasn't been tested all that much.
6215 * som.c (SOM_LST_HASH_SIZE, SOM_LST_MODULE_LIMIT): Define.
6216 (struct som_misc_symbol_info): New structure to hold info necessary

6234 * coff-rs6000.c: Add Lynx core file support, use HOST_AIX, where
6236 * rs6000-core.c: Use HOST_AIX instead of COREFILES_PLEASE.

6718 (only testing for m68k and vax at the moment); do verify that the
6719 preprocessor didn't trash the arch name inside the string version.

6750 bfd_som_set_subsection_attributes): Change parameters from char
6751 to int. Following a prototype with an old-style function definition

6858 use get_value to get the symbol value and check for undefined
6860 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6861 undefined, look it up in the linker hash table.
6863 * aoutx.h (translate_symbol_table): The string index 0 has a

6888 The sparc (and possibly other?) NLM format requires a different
6889 way to write exports, so add a write_export field to the backend
6890 data (and set it to NULL for everything but the sparc).
