0b6876a0c0 The reason is that the event is supposed to put the instructions ready to execute for next cycle. And the FUCompletion event has a lower priority than CPU tick event. It is called after the iew->tick() for current cycle has already been executed and the issueToExecuteQueue has already advanced this time. And assume the issueToExecuteLatency is 1, to catch up, the increasement should be made at access(-1) instead of access(0). Otherwise I found it could increase the actual op_latency of the instructions to execute by 1 cycle and potentially put the simulated CPU into a permanent idle state.

6c5a3ab8b2 Add ReadRespWithInvalidate to handle multi-level coherence situation 
where we defer a response to a read from a far-away cache A, then later
defer a ReadExcl from a cache B on the same bus as us.  We'll assert
MemInhibit in both cases, but in the latter case MemInhibit will keep
the invalidation from reaching cache A.  This special response tells
cache A that it gets the block to satisfy its read, but must immediately
invalidate it.
