AMD64 currently does not handle the same intrinsics as x86 (SIN, COS, LOG, etc).

const bool Matcher::modFSupported(void) { return false; }
const bool Matcher::modDSupported(void) { return false; }
const bool Matcher::sinDSupported(void) { return false; }
const bool Matcher::cosDSupported(void) { return false; }
const bool Matcher::tanDSupported(void) { return false; }
const bool Matcher::atanDSupported(void) { return false; }

EVALUATION Need to add instructions in amd64.ad ###@###.### 2004-07-28 Added SIN/COS/LN2/LOG10 and Almabench scores went from ~60seconds a run to ~30seconds a run. With the caveat that Almabench is nothing more than a test of how fast SIN/COS are. ###@###.### 2004-08-17
