C99: Define a NAN macro in <math.h> which evaulates to a constant expression of a single-precision quiet NaN; only to be defined on platforms that do support this value. 1999-12-23 13:15:05 +03:00
Coldfire FPU looks like the 68010 FPU (no long double) 2013-07-19 02:17:57 +04:00			`#if !defined(__mc68010__) && !defined(__mcoldfire__)`
#define __HAVE_LONG_DOUBLE on platforms which implement a distinct `long double' type. 2003-10-28 03:55:28 +03:00			`#define __HAVE_LONG_DOUBLE`
Don't define __HAVE_LONG_DOUBLE for __mc68010__. 2003-10-30 16:18:24 +03:00			`#endif`
Clean up some rampant code duplication wrt ieee number handling: - Add alignment-safe double and float unions. - Use the above for the __infinity and __nan constants on all architectures that use the standard ieee754 representation of those constants. - Add a single copy of various ieee754 math functions (frexp, isinf, isnan, ldexp and modf) that had numerous duplicates among the arch-specific directories. - Use the above functions on all architectures where the generic C versions where used. Architectures that had local assembly routines are untouched (for those functions only). 2002-02-19 16:08:12 +03:00			`#define __HAVE_NANF`
