It might be a while for me to rewrite the tree combiner so unassigning for now.

------- Additional Comments From pinskia at gcc dot gnu dot org 2004-08-29 19:36 -------
The two FIXMEs in my tree combiner:
/* FIXME: do not abort for the call case as this can happen for an example
-cos(-a) == cos (a) but this does not show up here as we reject it when
calculating the size. */
/* If we have more than three or zero, we cannot handle this case so we
return a relatively huge count saying we cannot handle it.
FIXME: Handle the cost of a call expression. */

I should note that cos(-x) == cos(x);
