Hal,
Since PPCHazardRecognizer is not derived from ScoreboardHazardRecognizer, you'll need to initialize MaxLookAhead to the max depth of your target's itinerary.
See how this is done in the ScoreboardHazardRecognizer ctor:
> MaxLookAhead = ScoreboardDepth;

...rdRecognizer at this point? It looks like the custom
bundling logic could be implemented on top of the scoreboard recognizer
(that seems similar to what ARM's recognizer is doing).

...lar to what ARM's recognizer is doing).
Also, how does the ARM hazard recognizer get away with not implementing
RecedeCycle?
