------- Comment #1 from bonzini at gnu dot org 2007-02-22 08:27 -------
It's actually a small oversight in fwprop, which is supposed to replace
find_best_addr indeed.
The patch indicated in the URL is enough for dataflow-branch; on mainline you
need also http://gcc.gnu.org/ml/gcc-patches/2007-02/msg01797.html because of a
bug in df that is already fixed on the branch.
