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.)
