--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. .optimized already has an unconditional abort() call and forwprop2
changes it to that.
Applying pattern match.pd:2322, gimple-match.c:2002
gimple_simplified to _15 = d.2_9 - _5;
_16 = _15 & 254;
_12 = (int) _16;
Applying pattern match.pd:1853, generic-match.c:5128
Replaced '_12 != -2' with '1'
gimple_simplified to if (1 != 0)
