Detailed Description

template<typename BlockPtrTy, bool Forward = true>
class llvm::VPHierarchicalChildrenIterator< BlockPtrTy, Forward >

Iterator to traverse all successors/predecessors of a VPBlockBase node, including its hierarchical successors/predecessors:

A
|

+--—+ <- Region R

b
...

e

+--—+ | B

Forward == true: Region blocks themselves traverse only their entries directly. Region's successor is implictly traversed when processing its exiting block. children(A) == {R} children(R) == {b} children(e) == {B}

Forward == false: Region blocks themselves traverse only their exiting blocks directly. Region's predecessor is implicitly traversed when processing its entry block. children(B) == {R} children(R) == {e} children(b) == {A}

The scheme described above ensures that all blocks of the region are visited before continuing traversal outside the region when doing a reverse post-order traversal of the VPlan.
