    Kenner, do you mean that given the expression &VAR, you are expecting a
    VUSE operand for 'VAR'?   That will never happen, because that is not a
    reference to 'VAR'.  Apologies if I misunderstood.

In this particular case, Zdenek did expect it.  And the lack of "tracking"
of the operand of an ADDR_EXPR was related to the DCE problem you were
going to look at, so I thought they might be related.  I don't know enough
about the issue to form an opinion about what *I* expect to see.
