------- Comment #12 from rguenth at gcc dot gnu dot org 2009-01-17 12:58 ------- Note that we have to be very careful here because
struct X {
int i;
};
struct A {
int i;
};
struct B {
struct A a;
int j;
};
int foo (struct X *p, struct B *q)
{
p->i = 0;
q->a.i = 1;
return p->i;
}
may be aliasing. One need to consult the C standard and defect reports again
for the "common initial sequence" in structs stuff.
