Detailed Description

This interface is used to plug different priorities computation algorithms into the list scheduler.

It implements the interface of a standard priority queue, where nodes are inserted in arbitrary order and returned in priority order. The computation of the priority and the representation of the queue are totally up to the implementation to decide.

◆ scheduledNode()

As each node is scheduled, this method is invoked.

This allows the priority function to adjust the priority of related unscheduled nodes, for example.

Reimplemented in llvm::ResourcePriorityQueue, and llvm::LatencyPriorityQueue.
