[rguenth at gcc dot gnu dot org]

------- Comment #3 from rguenth at gcc dot gnu dot org  2007-11-18 14:44 -------
Confirmed.  Called from tree_ssa_dce_loop ().

# VUSE <rc_47, rc_47> { rc }
# rc_45 = VDEF <rc_45> { rc }
rc_45 = D.1197_49 != 0 ? rc_47 : rc_47

WTF?  tree if-conversion generates this crap.
