Accuracy of Mathematical Functions

[Paul Zimmermann]

       Dear all,

a new update of our comparison is available:

https://members.loria.fr/PZimmermann/papers/accuracy.pdf

Main changes in this update:

* GNU libc now provides 21 correctly-rounded functions in single precision
  (integrating the CORE-MATH code)
* LLVM-libc provides more correctly-rounded functions
