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.
