axeldavy added a comment.

This update reworks significantly the structure of the scheduler.

. Put all the code to handle register tracking into a class SISchedulerRPTracker. The class handles lane tracking as described previously.
. The code to schedule inside blocks has been completly reworked to use this class. Thus it doesn't use default RPTracker anymore, doesn't call handleMove, etc and is thus very significantly faster.
