: Probably never.  Portability has always been more important than

  If someone makes a compiler which can optimize code for SSE or 3DNow,
it will be absolutely possible to compile an optimized version.
  However, such a compiler is hardly possible (for the reason Ron stated;
if you use doubles, the compiler _can't_ optimize them to floats).
