15 * information about the tree.
16 *
17 * "guard" contains conditions that should still be enforced by
18 * some ancestor of the current tree. In particular, the already
19 * generated tree assumes that these conditions hold, but may not
20 * have enforced them itself.
21 * The guard should not contain any unknown divs as it will be used
22 * to generate an if condition.
23 *
24 * "enforced" expresses constraints that are already enforced by the for
25 * nodes in the current tree and that therefore do not need to be enforced
26 * by any ancestor.
27 * The constraints only involve outer loop iterators.
