class VPWidenPHIRecipe

Declaration

class VPWidenPHIRecipe : public VPHeaderPHIRecipe { /* full declaration omitted */ };

Description

A recipe for handling header phis that are widened in the vector loop. In the VPlan native path, all incoming VPValues & VPBasicBlock pairs are managed in the recipe directly.

Inherits from: VPHeaderPHIRecipe

Member Variables

private SmallVector<llvm::VPBasicBlock*, 2> IncomingBlocks

List of incoming blocks. Only used in the VPlan native path.
