+==================== work095, patch #12.
+
+Enable using overload built-ins for 128-bit floating point.

+
+       * config/rs6000/rs6000-builtin.cc (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/rs6000-c.cc (rs6000_builtin_type_compatible):
+       Don't consider _Float128 and long double under
+       -mabi=ieeelongdouble to be compatible for built-in functions.  Use
+       overloading instead.
+       * config/rs6000/rs6000.md (IFKF): Delete.
+       (IFKF_reg): Delete.
+       (@extenddf<mode>2_fprs): Remove extra test for
+       TARGET_LONG_DOUBLE_128.
+       (@extenddf<mode2>_vsx): Likewise.
+       (extendiftf2): Allow __ibm128 even if _Float128 is not supported.
+       (extendkfif2): New insn.
+       (extendtfkf2): Allow __ibm128 even if _Float128 is not supported.
+       (extendtfif2): Likewise.
+       (trunckfif2): New insn.
+       (trunctfif2): Allow __ibm128 even if _Float128 is not supported.
+       (extendkftf2_internal): Split extend<mode>tf2_internal and
+       extendtf<mode>2_internal into separate insns that handle either
+       conversions between IEEE 128-bit types or between IBM 128-bit types.
+       Set the type and insn length correctly.
+       (extendtfkf2_internal): Likewise.
+       (extendiftf2_internal): Likewise.
+       (extendtfif2_internal): Likewise.

 ==================== work095, patch #11.
 
 Make __float128 and __ibm128 use different types from long double.
