Accuracy of Mathematical Functions

       Dear all,

a new update of our comparison is available:

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

Main remarks about this update:

* more correctly-rounded functions in GNU libc and LLVM libc

* the Intel Math Library provides some cr_xxx functions: the user can choose
  between the default function (log) and the correctly rounded one (cr_log)

* about two years after the adoption of C23, very few libraries implement
  the new C23 functions

Specific to Newlib, we are still testing 4.6.0, with the following issues:
hypotl(x,0) gives infinity for x >= 2^8192, and C23 functions are still
missing.
