Re: [PATCH], PowerPC IEEE 128-bit patch #7 (revised #2), Subpatch #03


This patch defines 3 macros to tell the user whether -mfloat128 is enabled or
not, and whether long double is IBM extended double or IEEE 128-bit floating
point.

I have built the compiler with this patch and the previous subpatches (1 and
2).  I have bootstrapped the compiler with all 16 subpatches installed, and
there were no regressions.  Is it ok to install in the trunk?

	* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): Define
	__FLOAT128__ if -mfloat128. Define __LONG_DOUBLE_IEEE128__ if long
	double is IEEE 128-bit. Define __LONG_DOUBLE_IBM128__ if long
	double is IBM extended double.
