	* config/rs6000/rs6000.c (rs6000_init_libfuncs): Split libfunc
	setup into 3 functions: init_float128_ibm, init_float128_ieee, and
	rs6000_init_libfuncs. If -mfloat128, add IFmode functions for all
	of the traditional names that TFmode uses for handling IEEE
	extended double. If -mfloat128, add KFmode functions for all of
	the emulation functions. If -mabi=ieeelongdouble and -mfloat128,
	make TFmode use the same emulation functions as KFmode.
	(init_float128_ibm): Likewise.
	(init_float128_ieee): Likewise.
	(rs6000_generate_compare): For IEEE 128-bit floating point
	comparisons, call the unordered comparison function instead of the
	ordered comparison function.
	(rs6000_expand_float128_convert): Deal with operands that are
	memory operands. Restructure the code to use a switch statement on
	the mode. Add support for TFmode defaulting to either IBM extended
	double or IEEE 128-bit floating point. If the underlying types are
	the same, use a move instead of a conversion function.
	(TARGET_C_MODE_FOR_SUFFIX): Define 'q' and 'Q' as the suffix to
	use for IEEE 128-bit floating point constants with -mfloat128.
	(rs6000_c_mode_for_suffix): Likewise.
	(TARGET_INVALID_BINARY_OP): Do not allow inter-mixing of IEEE
	128-bit floating point with IBM extended double floating point.
	(rs6000_invalid_binary_op): Likewise.
	(rs6000_gen_le_vsx_permute): On little endian systems generate a
	ROTATE insn instead of VEC_SELECT for IEEE 128-bit floating point
	types that can go in vector registers.

	point types that can go in vector registers on little endian
	PowerPC systems.
	(mark_swaps_for_removal): Likewise.
	(rs6000_analyze_swaps): Likewise.
	(rs6000_mangle_type): Use U10__float128 for IEEE 128-bit floating point.

	rework IEEE 128-bit floating point insns to deal with TFmode being
	either IBM extended double or IEEE 128-bit floating point.
	(IFKF): Likewise.
	(IBM128): Update iterator to add condition that the mode is IBM
	extended double.
	(IEEE128): New iterator for IEEE 128-bit floating point.
	(TFIFKF): Rename TFIFKF iterator to FLOAT128.
	(FLOAT128): Likewise.
	(signbit<mode>2): FLOAT128_IBM_P condition test moved into IBM128
	iterator.
	(neg<mode>2): Replace TFIFKF iterator with FLOAT128. Add support
	for TFmode being IEEE 128-bit floating point. Use IEEE128 iterator

add, subtract, multiply, divide; unary arithmetic operators;
relational operators; equality operators; and conversions to and from
integer and other floating types. Use a suffix @samp{w} or @samp{W}
in a literal constant of type @code{__float80} and @samp{q} or @samp{Q}

corresponding internal complex type, @code{XCmode} for @code{__float80}

in a literal constant of type @code{__float80} or type
@code{__ibm128}. Use a suffix @samp{q} or @samp{Q} for @code{_float128}.
On the i386, x86_64, IA-64, and HP-UX targets, you can declare complex
types using the corresponding internal complex type, @code{XCmode} for
@code{__float80} type and @code{TCmode} for @code{__float128} type:
@smallexample
typedef _Complex float __attribute__((mode(TC))) _Complex128;
typedef _Complex float __attribute__((mode(XC))) _Complex80;
@end smallexample
On PowerPC Linux, Freebsd and Darwin systems, the default for
@code{long double} is to use the IBM extended floating point format
that uses a pair of @code{double} values to extend the precision.
This means that the mode @code{TCmode} was already used by the
traditional IBM long double format, and you would need to use the mode
@code{KCmode}:
@smallexample
typedef _Complex float __attribute__((mode(KC))) _Complex128;
@end smallexample
Not all targets support additional floating-point types. @code{__float80}
and @code{__float128} types are supported on x86 and IA-64 targets.
The @code{__float128} type is supported on hppa HP-UX targets.
The @code{__float128} type is supported on hppa HP-UX.
The @code{__float128} type is supported on PowerPC systems by default
if the vector scalar instruction set (VSX) is enabled.
On the PowerPC, @code{__ibm128} provides access to the IBM extended
double format, and it is intended to be used by the library functions
that handle conversions if/when long double is changed to be IEEE
128-bit floating point.
