Bill Wendling [Wed, 13 Jan 2010 23:23:17 +0000 (23:23 +0000)]
When the visitSub method was split into visitSub and visitFSub, this xform was
added to the FSub version. However, the original version of this xform guarded
against doing this for floating point (!Op0->getType()->isFPOrFPVector()).

This is causing LLVM to perform incorrect xforms for code like:

void func(double *rhi, double *rlo, double xh, double xl, double yh, double yl){
  double mh, ml;
  double c = 134217729.0;

  up = xh*c;
  u1 = (xh - up) + up;
  u2 = xh - u1;

  vp = yh*c;
  v1 = (yh - vp) + vp;
  v2 = yh - v1;

  mh = xh*yh;
  ml = (((u1*v1 - mh) + (u1*v2)) + (u2*v1)) + (u2*v2);
  ml += xh*yl + xl*yh;

  *rhi = mh + ml;
  *rlo = (mh - (*rhi)) + ml;
}

The last line was optimized away, but rl is intended to be the difference
between the infinitely precise result of mh + ml and after it has been rounded
to double precision.

and that is pattern matched in a way that guarantees SP is used. There is
