17 OpenLibm builds on Linux, Mac OS X, Windows, FreeBSD, OpenBSD, and DragonFly BSD.
18 It builds with both GCC and clang. Although largely tested and widely
19 used on x86 architectures, OpenLibm also supports ARM and

3132 i686. GCC 4.8 is the minimum requirement for correct codegen on
3233 older 32-bit architectures.

35 <p><a href="http://www.openlibm.org">OpenLibm</a> is an effort to have a high quality, portable, standalone
36 C mathematical library (<a href="http://en.wikipedia.org/wiki/libm"><code>libm</code></a>).
37 It can be used standalone in applications and programming language
38 implementations.</p>
39
40 <p>The project was born out of a need to have a good <code>libm</code> for the
41 <a href="http://www.julialang.org">Julia programming langage</a> that worked
42 consistently across compilers and operating systems, and in 32-bit and
43 64-bit environments.</p>

48 <p>The OpenLibm code derives from the <a href="http://svnweb.freebsd.org/base/head/lib/msun/">FreeBSD

51 implementations, which in turn derive from <a href="http://www.netlib.org/fdlibm/">FDLIBM
52 5.3</a>. Over and above that, OpenLibm itself has received a number of patches to make it platform independent and portable.</p>
