Author: marino Date: Tue Jan 31 20:02:42 2017 New Revision: 432948 URL: https://svnweb.freebsd.org/changeset/ports/432948 Log: math/opensolaris-libm: Second *BSD release Interestingly, this update comes 11 years to the days after the original source was released. This resolves the OpenLibm testsuite failures for the double variant of Bessel functions (seen always on Clang and on GCC when fno-builtin switch set) and the gamma/lgamma failures for 0.5 and 3.0 arguments. The associated implementions were replaced with the 1993 SunPro versions found in all BSD-based math libraries. The failures were of the off-by-1-bit type explained by floating point rounding. Now all float and double tests found in OpenLibm's testsuite pass.
