	gcc            : ChangeLog expmed.c genmodes.c machmode.h 
	                 varasm.c 
	gcc/config/ia64: hpux.h ia64-modes.def ia64-protos.h ia64.c 
	                 ia64.h ia64.md lib1funcs.asm t-ia64 

Log message:
	* 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.
