+==================== work093, patch #7
+
+__float128 and __ibm128 always gets different internal types.

+
+gcc/
+
+	* config/rs6000/rs6000-builtin.cc (rs6000_init_builtins): Always
+	create a new tree node for __ibm128, even if long double uses the
+	IBM 128-bit format.  Always create a new tree node for __float128,
+	even if long double uses the IEEE 128-bit format.
+	(rs6000_expand_builtin): Remove all of the code that changed
+	KFmode built-in functions into TFmode, since these functions now
+	support overloading between KFmode and TFmode.
+	* config/rs6000/rs600.cc (reg_offset_addressing_ok_p): Allow
+	IFmode to use offset addresses.
+	(init_float128_ibm): Remove checks for hardware floating point for
+	the IBM 128-bit comparisons.
+	(init_float128_ieee): Do not create __mulkc3 and __divkc3 since
+	__float128 always creates these functions.
+	(rs6000_init_libfuncs): Create complex multiply and divide for
+	long double if long double uses the IEEE 128-bit encoding.
+	(rs6000_libgcc_floating_mode_supported_p): Allow KFmode if IEEE
+	128-bit floating point is supported.  Allow IFmode if either IEEE
+	128-bit floating point is supported or long double is IBM
+	128-bit.
+	(rs6000_floatn_mode): Always return KFmode for IEEE 128-bit.  Do
+	not return TFmode, even if long double uses the IEEE 128-bit
+	format.
+	(rs6000_c_mode_for_suffix): The 'q' suffix always uses KFmode,
+	even if long double uses the IEEE 128-bit encoding.
+
+libgcc/
+
+	* config/rs6000/float128-ifunc.c (__multc3_ieee128): Add ifunc
+	support.
+	(__divtc3_ieee128): Likewise.
+	* config/rs6000/quad-float128.h (__multc3_ieee128): Add
+        Declaration.
+        (__divtc3_ieee128): Likewise.
