class VPAllSuccessorsIterator

Declaration

template <typename BlockPtrTy>
class VPAllSuccessorsIterator { /* full declaration omitted */ };

Description

Iterator to traverse all successors of a VPBlockBase node. This includes the entry node of VPRegionBlocks. Exit blocks of a region implicitly have their parent region's successors. This ensures all blocks in a region are visited before any blocks in a successor region when doing a reverse post-order

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:2369

Templates

BlockPtrTy

Member Variables

private BlockPtrTy Block

private size_t SuccessorIdx

Index of the current successor. For VPBasicBlock nodes, this simply is the index for the successor array. For VPRegionBlock, SuccessorIdx == 0 is used for the region's entry block, and SuccessorIdx - 1 are the indices for the successor array.

Method Overview

• public VPAllSuccessorsIterator<BlockPtrTy>(BlockPtrTy Block, size_t Idx = 0)
• public VPAllSuccessorsIterator<BlockPtrTy>(const VPAllSuccessorsIterator<BlockPtrTy> & Other)
• private template <typename T1>static T1 deref(T1 Block, unsigned int SuccIdx)
• public static VPAllSuccessorsIterator<BlockPtrTy> end(BlockPtrTy Block)
• private static BlockPtrTy getBlockWithSuccs(BlockPtrTy Current)
