SPR_CMPEXCH_VALUE should be present in your cpu structure, should be a TCGv like all of your other registers, and this expands to a simple move. You will probably need to dispatch on the SPR number. Some of these will be normal moves to special register slots. Some of these may require a function call in order to handle the side effects. r~
