+==================== work097, patch001
+
+Allow __ibm128 even if IEEE 128-bit floating point is not supported.
+
+This set of patches changes the GCC compiler to allow the use of the __ibm128
+keyword if we have IEEE 128-bit floating point support enabled or if long double
+is 128-bits.
+
+In addition, checks for requiring hardware floating point to use __ibm128 have
+been removed.  This fixes PR target/105534.

+	* config/rs6000/rs600.cc (init_float128_ibm): Remove checks for hardware
+	floating point for the IBM 128-bit comparisons.
+	(rs6000_init_libfuncs): Create IBM 128-bit floating point support even
+	if we don't support IEEE 128-bit floating point.
+	(rs6000_scalar_mode_supported_p): Allow __ibm128 even if we don't
+	support _Float128.
+	* config/rs6000/rs6000.h (FLOAT128_IBM_P): Remove checks for
+	-mhard-float.
+	(TARGET_IBM128): New macro.
