--- Comment #11 from Sebastian Pop <spop at gcc dot gnu.org> 2010-12-01 20:15:29 UTC ---
In this code:
<bb 3>:
q_5 = &MEM[(void *)q_1 + 4294967288B];
<bb 4>:
# q_1 = PHI <q_3(2), q_5(3)>
if (q_1 != p_2(D))
goto <bb 3>;
else
goto <bb 5>;
scev analysis is able to determine that q1 = {q_3, +, -8}_1 and in the
same time, scev fails to analyze q5. And that triggers a rewrite of
q_5 out of SSA making the scev analysis of q1 impossible.

I see the same failure on amd64-linux with
./cc1 -m32 -Os -fgraphite-identity pr45297.c
I will have a look at this.
