+==================== work098, patch #3
+
+Add 'w' suffix for __ibm128 constants.
+
+In the documentation, we mention that 'w' or 'W' can be used as a suffix for
+__ibm128 constants.  We never implemented this.  This patch fixes that.

+
+	* config/rs6000/rs6000.cc (rs6000_c_mode_for_suffix): Allow 'w' or 'W'
+	for __ibm128 constants.
+
+gcc/testsuite/
+
+	* gcc.target/powerpc/ibm128-suffix.c: New test.
+
+==================== work098, patch #2
+
+Allow __ibm128 with -msoft-float (PR target/105334)
+
+This patch allows __ibm128 to be used on systems with software floating point
+enabled.  Previously, we required hardware floating point to be enabled to use
+the __builtin_pack_ibm128 and __builtin_unpack_libm128 built-in functions.  This
+fixes PR target/105334.

+==================== work098, patch #1
+
+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.
