class VPPredInstPHIRecipe

Declaration

class VPPredInstPHIRecipe : public VPRecipeBase { /* full declaration omitted */ };

Description

VPPredInstPHIRecipe is a recipe for generating the phi nodes needed when control converges back from a Branch-on-Mask. The phi nodes are needed in order to merge values that are set under such a branch and feed their uses. The phi nodes can be scalar or vector depending on the users of the value. This recipe works in concert with VPBranchOnMaskRecipe.
