a2de53aeeb Reverted to naming IFUStallD to IFUStallF and LSUStallW to LSUStallM. These are generated in the F and M stage.
Generate WFIStallM in the privileged unit rather than generate in hazard.
Cleaned up the hazard cause logic to be consistent across all causes.

c8c73f47d2 CacheEn enables reading or writing the cache memory arrays. This is only disabled if we have a stall while in the ready state and we don't have a cache miss. This is a cache hit, but we are stalled. 2022-12-21 22:13:05 -06:00
