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