; 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.
