* genmodes.c (struct mode_data): Add contained and next_cont
fields.
(complete_mode): Maintain linked list of modes that have a
given component.
(emit_mode_unit_size): Delete.
(emit_mode_nunits): New.
(emit_insn_modes_c): Update to match.
(emit_mode_adjustments): Propagate size and alignment
adjustments from component modes to their containers.
* machmode.h (mode_unit_size): Delete.
(mode_nunits): New.
(GET_MODE_NUNITS): Just return the value in the table.
(GET_MODE_UNIT_SIZE): Compute using GET_MODE_INNER and
GET_MODE_SIZE.
* expmed.c (store_bit_field, extract_bit_field): Can use a
plain move instruction if bitsize >= GET_MODE_BITSIZE of
destination/source mode, respectively.
* varasm.c (assemble_real): Write out the full size of the
constant, not just its bitsize.
(output_constant): Honor TYPE_MODE of TREE_REAL_CSTs.
* config/ia64/ia64-modes.def: Define XFmode as well as TFmode.
Use ADJUST_BYTESIZE and ADJUST_ALIGNMENT to set size and
alignment of XF and TF modes in compliance with ia64 ABIs.
Can now hardwire the format of both modes.
* config/ia64/ia64.c: Change TFmode to XFmode wherever appropriate.
(general_tfmode_operand, destination_tfmode_operand)
(tfreg_or_fp01_operand, spill_tfmode_operand): Rename to
general_xfmode_operand, destination_xfmode_operand,
xfreg_or_fp01_operand, spill_xfmode_operand respectively.
(ia64_init_builtins): Make TYPE_PRECISION of fpreg_type
and float80_type be 96 so they get XFmode. Use !TARGET_HPUX,
not INTEL_EXTENDED_IEEE_FORMAT, to decide how to define
__float128.
* config/ia64/ia64.h: Default TARGET_HPUX to 0.
Change TFmode to XFmode wherever appropriate. Remove all
references to INTEL_EXTENDED_IEEE_FORMAT.
(LONG_DOUBLE_TYPE_SIZE): Varies with TARGET_HPUX.
(LIBGCC2_LONG_DOUBLE_TYPE_SIZE): Define (always 96).
(PREDICATE_CODES): Update to match function renames.
* config/ia64/ia64.md: Change TF to XF throughout; rename all
patterns to match. Remove all references to
INTEL_EXTENDED_IEEE_FORMAT. Update predicate calls to match
function renames.
* config/ia64/ia64-protos.c: Update all prototypes to match
renamed functions.
* config/ia64/hpux.h: Redefine TARGET_HPUX to 1.
Remove all references to INTEL_EXTENDED_IEEE_FORMAT.
* config/ia64/lib1funcs.asm: Add __divxf3 as new name for
__divtf3; keep old name for backward compatibility.
(L__compat): New section providing forwarding stubs for
__fixtfti, __fixunstfti, __floattitf.
* config/ia64/t-ia64: Add __compat to LIB1ASMFUNCS.
