class VPInstruction

Declaration

class VPInstruction : public VPUser, public VPRecipeBase { /* full declaration omitted */ };

Description

This is a concrete Recipe that models a single VPlan-level instruction. While as any Recipe it may generate a sequence of IR instructions when executed, these instructions would always form a single-def expression as the VPInstruction is also a single def-use vertex.
