Ah, we start from the exit block with ANTIC_IN {} and go to its predecessors
getting just EXP_GEN - TMP_GEN there. Not unsound.

Do you mean sth like the following? Simply assuming that the maximal-set is
all ones and obviously translating all ones also results in all ones.

Equivalent to that would be to clean ANTIC_IN using the maximal set - that is,
do not allow expressions in ANTIC_IN that are not in the maximal set.

We again have ANTIC_IN/OUT oscillation
ANTIC_OUT[] := { x_2 (0001), y_3 (0002), {pointer_plus_expr,x_2,4} (0011) }
ANTIC_IN[] := { x_2 (0001), y_3 (0002), {pointer_plus_expr,x_2,4} (0011) }
ANTIC_OUT[] := { x_2 (0
