------- 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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34245
