- * The layout hash is used during the equivalency checking.  We have a node in
- * the child graph that may be equivalent to a node in the parent graph.  To
- * find the corresponding node (if any) in the parent, we need a quick way to
- * get to all nodes in the parent that look like the node in the child.  Since a
- * large number of nodes don't have names, we need to incorporate the layout of
- * the node into the hash.  If we don't, we'll end up with the vast majority of
- * nodes in bucket zero, with one or two nodes in each of the remaining buckets.
- *
- * There are a couple of constraints, both of which concern forward
- * declarations.  Recall that a forward declaration tdesc is equivalent to a
- * tdesc that actually defines the structure or union.  As such, we cannot
- * incorporate anything into the hash for a named struct or union node that
- * couldn't be found by looking at the forward, and vice versa.
