1## OpenLibm
2
3OpenLibm contains code that is covered by various licenses.
4
5The OpenLibm code derives from the FreeBSD msun and OpenBSD libm
6implementations, which in turn derives from FDLIBM 5.3. As a result, it
7has a number of fixes and updates that have accumulated over the years
8in msun, and also optimized assembly versions of many functions. These
9improvements are provided under the BSD and ISC licenses. The msun
10library also includes work placed under the public domain, which is
11noted in the individual files. Further work on making a standalone
12OpenLibm library from msun, as part of the Julia project is covered
13under the MIT license. The test files, test-double.c and test-float.c
14are under the LGPL.
