class RNSuccIterator

Declaration

template <class NodeRef, class BlockT, class RegionT>
class RNSuccIterator { /* full declaration omitted */ };

Description

Hierarchical RegionNode successor iterator. This iterator iterates over all successors of a RegionNode. For a BasicBlock RegionNode it skips all BasicBlocks that are not part of the parent Region. Furthermore for BasicBlocks that start a subregion, a RegionNode representing the subregion is returned. For a subregion RegionNode there is just one successor. The RegionNode representing the exit of the subregion.
