   7 /* An isl_schedule_node points to a particular location in a schedule tree.
   8  *
   9  * "schedule" is the schedule that the node is pointing to.
  10  * "ancestors" is a list of the n ancestors of the node
  11  * that is being pointed to.
  12  * The first ancestor is the root of "schedule", while the last ancestor
  13  * is the parent of the specified location.
  14  * "child_pos" is an array of child positions of the same length as "ancestors",
  15  * where ancestor i (i > 0) appears in child_pos[i - 1] of ancestor i - 1 and
  16  * "tree" appears in child_pos[n - 1] of ancestor n - 1.
  17  * "tree" is the subtree at the specified location.
  18  *
  19  * Note that the same isl_schedule_tree object may appear several times
  20  * in a schedule tree and therefore does not uniquely identify a position
  21  * in the schedule tree.
