Hi Junmo,

Instead of adding a field to every MachineInstr, it might be better to concatenate the two memref lists in the case that they are unequal when being merged.
You could try to do something more complex like sorting the merged list and removing duplicates, but that might be overkill depending on how large these memref lists can get.
