PC relative call since those only occur in cases where the linker
can fix them up.

relative calls.

hppa_field_adjust to get a new value for R_DATA_ONE_SYMBOL
relocations in SOM.
(hppa_fix_adjustable): Refine somewhat.
config/tc-h8500.c, config/tc-hppa.c, config/tc-hppa.h, config/tc-sh.c,
config/tc-z8k.c: Don't rely on use of ".." when including header files.
* config/tc-rce.c: Ditto.
* config/obj-coff.c (fixup_segment): Reformat condition in an `if' statement.
objects and speed up the linker.

with a size field.
(hppa_elf_mark_end_function): Delete unneeded function.
(pa_build_unwind_subspace): For the 2nd unwind relocation, use

hppa_elf_mark_end_of_function anymore.
(pa_procend): Likewise.
(hppa_fix_adjustable): Only reject 32bit relocations for SOM.
(elf_hppa_final_processing): Simplify.
offset within the current subspace along with updating the
alignment of the subspace itself.
(pa_subspace): Default alignment to one byte rathern than zero
bytes to avoid setting alignment to log2(0).
(md_pseudo_table): Use pa_alignment for .align.
(S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
(obj_attach_unwind_info): Do not define. Not needed anymore.
* config/tc-hppa.c: Delete whitespace at EOL.
(struct hppa_fix_struct): Delete fx_unwind field and all references.
(fix_new_hppa): Last arg is now a pointer to an int. Do not
call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
fixups, store 32bits of unwind information in the fx_addnumber
field of the fixup.
(md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
pointer to 32 bits of unwind info.
(tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
pointer to the dummy symbol; set the addend field to fx_addnumber.
(pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
rather than &bfd_XXX_section.
throughout code.
(is_complex): Delete definition and support for complex relocation
types.
(tc_gen_reloc): Delete special unwind crud for ELF. Simplify and
rewrite ELF code based on 94-02-02 PA ELF draft spec.
(pa_build_unwind_subspace): Use standard PARISC_DIR32 relocs for
the unwind descriptors.
defaults for defined, private, and spnum fields for the
$TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
not reset the segment if just updating a space.
(pa_spaces_begin): Set BFD section flags for all built-in
subspaces.
(elf_tc_make_sections): Likewise.
(hppa_tc_make_sections, hppa_tc_symbol): Delete extern decls.
* config/tc-hppa.c (hppa_tc_make_sections): Delete function.
(hppa_tc_symbol): Likewise.
* config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
elf_tc_make_sections stuff. It was there to support PA braindamage
which has been fixed, and in the case of elf_tc_make_sections is
redundant with elf_tc_final_processing.
for each section.
(adjust_code_sections): New function. Adjusts the VMA for all the
$CODE$ subspaces.
* config/tc-hppa.c (md_assemble): Also handle creating a fixup
for the unwind descriptors if a function's label follows the
.PROC and .ENTRY directives.
(pa_entry): Don't set BSF_FUNCTION for the label symbol here; it
is done elsewhere. Don't create a fixup for the unwind
descriptors if the function's label has not been defined yet.
(pa_proc): For SOM, place each procedure within a new $CODE$
subspace. Adjust the segment and frag for the associated
function label if it exists.
(hppa_fix_new): Initialize segment field.
(md_apply_fix): Do nothing for pc-relative fixup which involves
crossing a segment boundary.
(pa_procend): Undefine the current label after handling .PROC
and .PROCEND directives.
(dummy_symbol): Make type "symbolS *". Change references as
appropriate.
here. Handle case where label may be defined after the .PROC.
(pa_proc): It is not an error if the procedure's label isn't
defined before the .PROC directive.
* tc.h (md_end): Don't declare it.
* config/tc-*.[ch] (md_end): Deleted, in cases where it doesn't do anything.
* config/tc-vax.c (vip_end): Deleted null function.
* config/tc-mips.c (md_mips_end): Renamed from md_end.
* config/tc-mips.h (md_mips_end): Declare.
(md_end): New macro, calls md_mips_end.
* write.c (write_object_file): Don't close output file.
* as.c (main): Close output file (if needed) after calling listing_print, which
should be after calling write_object_file, which sets the frag addresses.
const.
* config/obj-*.c, config/tc-*.c: Omit superfluous "return" statements at ends
of functions. Don't check for null return from hash_new, since it won't return
at all if there's no memory available. Also, check for null return from
hash_insert, rather than zero-length string, as success indicator.
Breaks with the HP compilers.
* config/tc-hppa.c (struct call_info): Remove fields which were
set but never used. Remove all code which sets those fields.
(struct subspace_dictionary_chain): Likewise.
(struct space_dictionary_chain): Likewise.
(pa_desc): Delete useless function. Delete all references.
(hppa_tc_make_sections): No need to count the number of symbols for
the symbol extension section.
SOM BFD backend.
(obj_som_copyright): New function. Much like obj_som_version.
* config/tc-hppa.c (obj_copyright): Define as appropriate for
SOM and ELF.
(pa_copyright): Just a stub now.
