Korey Sewell f98e9161a8 InOrder didnt have all it's params set to a default value, which is now required for M5 objects; Also, a # of values need to be reset to 0 (or the appropriate value) before we assume they are OK for use. 2009-03-04 13:17:05 -05:00
Korey Sewell 846f953c2b Give TimeBuffer an ID that can be set. Necessary because InOrder uses generic stages so w/o an ID there is no way to differentiate buffers when debugging 2009-03-04 13:16:49 -05:00
Korey Sewell e4aa4ca40c use numCycles instead of simTicks to determine CPI stat in InOrder 2009-03-04 13:16:48 -05:00
