Builtins for all the other floating-point classification macros are already
implemented and it would be nice to complete the set with __builtin_fpclassify
(could be certainly exploited in libstdc++, also)

------- Comment #2 from joseph at codesourcery dot com 2007-11-27 15:34 -------
Subject: Re: New: Missing __builtin_fpclassify
As previously discussed, this builtin would either need to be used in the
form
#define fpclassify(x) __builtin_fpclassify(FP_INFINITE, FP_NAN, FP_NORMAL,
FP_SUBNORMAL, FP_ZERO, (x))
or would need GCC to be configured with target-specific information about
FP_*, since the values of the FP_* macros are not standardized.

In my opinion, this would be already a nice improvement.

I see. At the moment, I'm not able to understand whether that is a major /
controversial change... I would appreciate some additional details, if
possible. Thanks.
