------- Comment #2 from rguenth at gcc dot gnu dot org 2010-04-18 20:14 -------
Loop invariant motion breaks this.
<bb 6>:
- g_313.0_6 = pretmp.4_9;
- *g_313.0_6 = 0B;
<bb 8>:
# m_21 = PHI <0(11), m_3(D)(2)>
+ g_313.8_12 = *g_313.0_6;
+ g_313.0_6 = pretmp.4_9;
goto <bb 5>;
we insert stmts not preserving ordering.
