Detailed Description

VPlan models a candidate for vectorization, encoding various decisions take to produce efficient output IR, including which branches, basic-blocks and output IR instructions to generate, and their cost.

VPlan holds a Hierarchical-CFG of VPBasicBlocks and VPRegionBlocks rooted at an Entry VPBlock.
