Since glibc 2.15, glibc has partial integration with -ffinite-math-only (or rather

the more often used -ffast-math)

In math.h, the following can be found:

#if defined __FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0

include <bits/math-finite.h>

#endif

These new functions can be found in libm have their own names, thus

some use cases like LD_PRELOAD are defeated.

However after some minor testing I found that many of these are still slower

than their AMD counterparts - is any integration (providing similar named functions) planned?
