class VPWidenPointerInductionRecipe

Declaration

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

Description

A pure virtual base class for all recipes modeling header phis, including phis for first order recurrences, pointer inductions and reductions. The start value is the first operand of the recipe and the incoming value from the backedge is the second operand.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1182

Inherits from: VPHeaderPHIRecipe

Member Variables

private const llvm::InductionDescriptor& IndDesc

private llvm::ScalarEvolution& SE

SCEV used to expand step. FIXME: move expansion of step to the pre-header, once it is modeled explicitly.

private bool IsScalarAfterVectorization
