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