FuncUnits = 0
CurrentState = 0
StateTrans = {first = 0, second = 0}

I understand that there is something wrong with the state machine but I
can't figure out what exactly. My scheduler description is the same as for
Hexagon or R600. So why would DFA would look any different for my target?
What could be the problem?
