Accuracy of Mathematical Functions

[Paul Zimmermann]

       Hi,

we have updated our comparison:

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

This update uses the same release of Newlib (4.2.0) as the previous one,
thus there is no much new for Newlib. The single precision issues are still
there (see "Notes about Newlib" on page 3).

The main change is that the LLVM library now implements a few
correctly-rounded routines in single precision (log, log10, log2,
hypot), and hypot in double precision.

Best regards,
Paul
