1## OpenLIBM 2 3OpenLIBM is an effort to have a high quality standalone LIBM 4library. It is meant to be used standalone in applications and 5programming language implementations. 6 7OpenLibm builds on Linux, Mac OS X, and Windows, and with little effort, 8should build on FreeBSD as well. It builds with both, GCC and clang. 9 10The OpenLIBM code derives from the FreeBSD msun implementation, which 11in turn derives from FDLIBM 5.3. As a result, it has a number of fixes and 12updates that have accumulated over the years in msun, and also optimized 13assembly versions of many functions. 14 15### Build instructions: 16 171. `make` or `make USEGCC=1` to build with GCC. 182. `make USECLANG=1` to build with clang. 19
