; 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.
