Detailed Description

This file declares the class VPlanVerifier, which contains utility functions to check the consistency of a VPlan.

This includes the following kinds of invariants:

  1. Region/Block invariants:
    • Region's entry/exit block must have no predecessors/successors, respectively.
    • Block's parent must be the region immediately containing the block.
    • Linked blocks must have a bi-directional link (successor/predecessor).
    • All predecessors/successors of a block must belong to the same region.
    • Blocks must have no duplicated successor/predecessor.
