| ; This test exercises MDNode hashing. For the nodes to be correctly uniqued, |
| ; the hash of a to-be-created MDNode has to match the hash of an |
| ; operand-just-changed MDNode (with the same operands). |
| ; |
| ; Note that these two assembly files number the nodes identically, even though |
| ; the nodes are in a different order. This is for the reader's convenience. |
