-==================== work095, patch #16 was reverted.
+==================== work095, patch #16
+
+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.

+	floating point for the IBM 128-bit comparisons.
+	(rs6000_init_libfuncs): Create IBM 128-bit floating point support even
