Author: das Date: Sat Oct 15 04:24:54 2011 New Revision: 226374 URL: http://svn.freebsd.org/changeset/base/226374 Log: Don't define FP_FAST_FMA on sparc64; with the recent fixes, fma() is no longer "fast" on sparc64. (It really wasn't to begin with, since the old implementation was using long doubles, and long doubles are emulated in software on sparc64.)
