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 VPBasicBlock.

createInitialVPlan()

VPlanPtr VPlan::createInitialVPlan ( Type *  InductionTy, PredicatedScalarEvolution &  PSE, bool  RequiresScalarEpilogueCheck, bool  TailFolded, Loop *  TheLoop  )

static

Create initial VPlan, having an "entry" VPBasicBlock (wrapping original scalar pre-header) which contains SCEV expansions that need to happen before the CFG is modified (when executing a VPlan for the epilogue vector loop, the original entry needs to be replaced by a new one); a VPBasicBlock for the vector pre-header, followed by a region for the vector loop, followed by the middle VPBasicBlock.

If a check is needed to guard executing the scalar epilogue loop, it will be added to the middle block, together with VPBasicBlocks for the scalar preheader and exit blocks. InductionTy is the type of the canonical induction and used for related values, like the trip count expression.
