LatencyPriorityQueue AvailableQueue

AvailableQueue - The priority queue to use for the available SUnits.

std::vector<SUnit*> PendingQueue

PendingQueue - This contains all of the instructions whose operands have been issued, but their results are not ready yet (due to the latency of the operation). Once the operands becomes available, the instruction is added to the AvailableQueue.

Topo - A topological ordering for SUnits.
