class VPWidenMemoryInstructionRecipe

Declaration

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

Description

A Recipe for widening load/store operations. The recipe uses the following VPValues: - For load: Address, optional mask - For store: Address, stored value, optional mask TODO: We currently execute only per-part unless a specific instance is provided.
