+==================== work097, patch010
+
+Update switching between KFmode to TFmode and IFmode to TFmode builtins
+
+This patch looks to see if the caller function wants TFmode (when long double is
+IEEE 128-bit) to switch the KFmode built-in functions to TFmode.
+
+It will look to see if the caller functions wants IFmode (when long double is
+IBM 128-bit) to switch the unpackif built-in function to unpacktf.
+
+It will look to see if a TFmode argument is passed (when long double is IBM
+128-bit) to switch the packif built-in function to packtf.

+gcc/
+
+	* config/rs6000/rs6000-builtin.cc (rs6000_expand_builtin): Update
+	switching from KFmode/IFmode built-in functions to TFmode built-in
+	functions.
+
+==================== work097, patch010
+
+Add ibm128_operand.
+
+Since we have 2 modes for IBM 128-bit (IFmode and TFmode if long double is IBM
+128-bit), this patch provides a new predicate (ibm128_operand) that allows
+combining a conversion from one mode to another.
