OpenLibm is an effort to have a high quality standalone LIBM
|
2011-12-31 08:18:43 +01:00
|
|
|
library. It is meant to be used standalone in applications and
|
2012-08-19 08:22:43 +02:00
|
|
|
programming language implementations.

OpenLibm also includes the AMOS library from Netlib, which is
|
|
|
|
|
a portable package for Bessel Functions of a Complex Argument
|
|
|
|
|
and Nonnegative Order. AMOS contains subroutines for computing Bessel
|
|
|
|
|
functions and Airy functions.
|
|
|
|
|
|
|
|
|
|
OpenLibm builds on Linux, Mac OS X, and Windows, and with little effort,
|
2012-07-03 17:30:34 +02:00
|
|
|
should build on FreeBSD as well. It builds with both, GCC and clang.

The OpenLIBM code derives from the FreeBSD msun implementation, which
|
2012-08-19 08:22:43 +02:00
|
|
|
in turn derives from FDLIBM 5.3. As a result, it has a number of fixes and
|
|
|
|
|
updates that have accumulated over the years in msun, and also optimized
|
|
|
|
|
assembly versions of many functions.
