------- Comment #1 from rguenth at gcc dot gnu dot org 2007-09-07 22:33 -------
Confirmed. FRE is guilty:
Replaced D.1654 with ap$p_12(ab) in D.1669_9 = D.1654;
from:
SCC consists of: D.1654_35
Value numbering D.1654_35 stmt = D.1654 = tmp_4;
No store match
Value numbering store D.1654 to tmp_4
Setting value number of D.1654_35 to D.1654_35
SCC consists of: D.1669_9
Value numbering D.1669_9 stmt = D.1669_9 = D.1654;
RHS D.1654 simplified to ap$p_12(ab) has constants 0
