[PATCH] D159136: [VPlan] Update successors/predecessors of region blocks directly (NFC).

[Ayal Zaks via Phabricator via llvm-commits]

Ayal added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/VPlanHCFGBuilder.cpp:319
   VPBasicBlock *ThePreheaderVPBB = Plan.getEntry();
   BB2VPBB[ThePreheaderBB] = ThePreheaderVPBB;
   ThePreheaderVPBB->setName("vector.ph");
----------------
buildPlain/HierarchicalCFG() is called following VPlan::createInitialVPlan(), which creates VPBB's (and will create more, plus Region, in D158333) directly rather than via getOrCreateVPBB(); so need to revisit them and update BB2VPBB, Loop2Region, setParent. Worth a comment.
