-; The structurize cfg pass used to do a post-order traversal to generate a list
-; of ; basic blocks and then operate on the list in reverse.  This led to bugs,
-; because sometimes successors would be visited before their predecessors.
-; The fix for this was to do a reverse post-order traversal which is what the
-; algorithm requires.
