================
Comment at: llvm/lib/Transforms/Vectorize/VPlanCFG.h:322
+vp_depth_first_nonrecursive(VPBlockBase *G) {
+  return depth_first(VPBlockNonRecursiveTraversalWrapper<VPBlockBase *>(G));
+}
----------------
nit: for completeness can also introduce `vp_depth_first_recursive(VPBlockBase *G)` which returns `depth_first(VPBlockRecursiveTraversalWrapper<VPBlockBase *>(G));` used elsewhere.

nit: "recursive" here stands for traversing inside regions of the hierarchical CFG. Perhaps a more accurate term is "deep" versus "flat" or "shallow", given the recursive nature of DFS itself.
