--- Comment #39 from Richard Biener <rguenth at gcc dot gnu.org> ---
Oh, and backprop is really intersect_uses () with
FOR_EACH_IMM_USE_STMT (stmt, iter, var)
{
being quadratic due to its stupid implementation (we really have many uses
of vars). If the pass can deal with duplicate stmt uses just fine using
FOR_EACH_IMM_USE_FAST is going to be faster.
