class VPActiveLaneMaskPHIRecipe

Declaration

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

Description

A recipe for generating the active lane mask for the vector loop that is used to predicate the vector operations. TODO: It would be good to use the existing VPWidenPHIRecipe instead and remove VPActiveLaneMaskPHIRecipe.
