relocs.
(elf_symbol_from_bfd_symbol): If there is an output section, use
the section index from that rather than the input section.
special function for all reloc entries.
* elf32-target.h (TARGET_LITTLE_SYM): Add SEC_CODE to
section_flags.
* libelf.h (elf_symbol_type): Remove desc, type and other fields.

(bfd_stat): Add, does fstat on a BFD.
* archive.c (_bfd_write_archive_contents): At end of file writing,
verify and possibly update the timestamp in the armap, if a BSD
archive. FIXME! Kludge recognizes BSD archive, rather than
vectoring properly. Should add to xvec.
(compute_and_write_armap): Move prototype to top, avoid PROTO.
(bsd_write_armap): Save timestamp and file location thereof, when
writing the armap in a BSD file.

references.
(nlm_swap_auxiliary_headers_{in,out}): The copyright length is
only one byte.
(nlm_get_symtab_upper_bound): Include debugging symbols in symbol
count.
(nlm_slurp_symbol_table): Make symlength unsigned. Read debugging
symbols as BFD local symbols.
(nlm_write_object_contents): Don't bother writing out exported
symbols more than once; they now appear in the symbol table more
than once (with and without a prefix) if necessary. Set offset
values to be non-zero as NLMLINK does.
These changes separate PA-SOM support from PA-ELF support.
A sun4-x-hppaosf assembler can now be built.
Include <stdlib.h> and <unistd.h>. Do not define malloc or free.
These changes separate PA-SOM support from PA-ELF support.
A sun4-x-hppaosf assembler can now be built.

global_sym_defined, symextn_contents, symextn_contents_real_size,
elf_hppa_stub_rootP, elf32_hppa_symextn_map, elf32_hppa_symextn_map_size): Rely
on default initialization.
(hppa_elf_gen_reloc_type): Macro "UNDEFINED" doesn't need a trailing semicolon.
(hppa_look_for_stubs_in_section): Introduce temporaries to make code more
readable in 80 columns.
* libhppa.h (all functions): Now inline under GNU C.
* elf32-hppa.c (AR_WARN): Give argument which caused the invalid argument
relocation.
(AR_UNIMP): Delete unused macro.
(hppa_elf_set_section_contents): Always return a value.
(elf32_hppa_backend_table_processing): Likewise.
(elf32_hppa_backend_section_processing: Likewise.
* som.c: New file containing SOM specific code extracted from hppa.c
* som.h: New file containing SOM specific code extracted from libhppa.h
* hppa.c: Deleted.
* libhppa.h: Delete SOM specific code. Add generic PA code which can be shared
by both SOM and ELF backends.
* Makefile.in: Replace hppa.c with som.c. elf32-hppa.o depends on libhppa.h
now.
* configure.in (hppa_vec): Needs som.o module instead of hppa.o.
* elf32-hppa.c: Include libhppa.h. Do not define BYTES_IN_WORD.
* elf32-hppa.h (hppa_reloc_field_selector_type): Delete now lives in libhppa.h.
(hppa_reloc_field_selector_type_alt): Likewise.

* elf32-hppa.c (elf32_hppa_backend_fake_sections): Add processing
of the .hppa_unwind section.
(bfd_shdr_from_section): Ditto.
(write_relocs): Don't change section contents for addend.
(elf_locate_sh): Return type is now always elf_internal_shdr, since the other
types were really aliases for this type anyways. Don't compile this function,
since it is static and doesn't appear to be used in this file.
(sym_is_global): Return non-zero for weak symbols. Abort if sec ptr is null.
(swap_out_syms): Reorder tests so function symbols can be weak.
(elf_slurp_symbol_table): Don't use BSF_EXPORT.
(elf_slurp_reloca_table): Make RELOC_PROCESSING section smaller by
extracting out some common code. Abort if BFD section symbol has null name.
(elf_slurp_reloc_table): Translate ELF section symbols into BFD section
symbols. Don't read section contents to fill in addend field.
* Merged from OSF:
Tue Jun 15 14:38:32 1993 Michael Meissner (meissner@osf.org)
* libelf.h (struct Elf_Sym_Extra): New structure to contain ELF
specific information for a symbol. Put in elf_sym_num, which
gives the external symbol number in the elf object file, since
local symbols must come before global symbols.
(elf_sym_extra): New macro.
(elf_symtab_map): Delete, in favor of using Elf_Sym_Extra.
* elfcode.h (elf_map_symbols): Use Elf_Sym_Extra to map internal
symbol number to external number. Store the address of the
Elf_Sym_Extra field for the symbol in the udata field.
(elf_write_object_contents): Use Elf_Sym_Extra to map out symbols.
Sun Jun 20 16:30:11 1993 Michael Meissner (meissner@osf.org)
* elfcode.h (elf_obj_tdata): Add field to count the size of the
array of pointers to section symbols.
(elf_map_symbols): Bump the max index of the section symbols so
that we don't overwrite memory. Store the max index into the
elf_obj_tdata field.
Sat Jun 19 10:12:27 1993 Michael Meissner (meissner@osf.org)
* elfcode.h (elf_obj_tdata): Add pointer to an array of pointers
to the section symbols we created. Remove unused field internal_syms.
(elf_map_symbols): Fill in array of pointers to section symbols. Only create
section symbols for sections that have SEC_ALLOC set, and have non-zero size.
(elf_symbol_from_bfd_symbol): If udata is NULL, and this is a section symbol,
look up the section in the list of section symbols, and set the udata pointer
appropriately. Otherwise, if udata is still NULL, fail an assertion, and use
0, instead of dropping core.
