* config/rs6000/rs6000.c (init_float128_ieee): Remove IEEE 128-bit
comparison functions in cmp_optab and ucmp_optab.
(rs6000_generate_compare): Rewrite IEEE 128-bit floating point
software emulation comparisons to only use __eqkf2, __gekf2,
__lekf2, and __unordkf2 functions.
(rs6000_invalid_binary_op): Add support for -mfloat128-convert.
* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): Define
__FLOAT128_HARDWARE__ if hardware IEEE 128-bit support is
available.
* config/rs6000/rs6000.opt (-mfloat128-convert): Add debug switch
to allow IBM extended double and IEEE 128-bit floating point to be
converted with default conversions.
* config/rs6000/rs6000.md (extendkftf2): Add converters between
KFmode and TFmode if -mabi=ieeelongdouble.
(trunctfkf2): Likewise.
(ieee128_mfvsrd): Split 64-bit integer conversions into 32-bit and
64-bit insns.
(ieee128_mfvsrd_64bit): Likewise.
(ieee128_mfvsrd_32bit): Likewise.
(ieee128_mtvsrd): Likewise.
(ieee128_mtvsrd_64bit): Likewise.
(ieee128_mtvsrd_32bit): Likewise.
* doc/extend.texi (Floating Types): Document that complex
__float128 does not work currently.
* doc/invoke.texi (RS/6000 and PowerPC Options): Document that
-mfloat128 is only supported on PowerPC 64-bit Linux systems.
