------- Comment #1 from pinskia at gcc dot gnu dot org 2006-03-02 21:35 -------
Confirmed, I don't know if this really a front-end issue or a tree opt issue as
we get in cpp:
x.a = 63;
D.2483_3 = x.a;
And then in FRE:
x.a = 63;
D.2483_3 = 63;
But x.a is not a full integer (there should be an and somewhere).
Note this does not have a problem in 4.0.x because FRE did not exist (well it
did) and PRE did not do stuff based on loads.
