class VPHeaderPHIRecipe

Declaration

class VPHeaderPHIRecipe : public VPRecipeBase, public VPValue { /* 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.

Parameters

unsigned char VPVID

unsigned char VPDefID

llvm::PHINode* Phi

llvm::VPValue* Start = nullptr

¶static inline bool classof(
    const llvm::VPRecipeBase* B)

Description

Method to support type inquiry through isa, cast, and dyn_cast.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1136

Parameters

const llvm::VPRecipeBase* B

¶static inline bool classof(const llvm::VPValue* V)

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1144

Parameters

const llvm::VPValue* V

¶void execute(llvm::VPTransformState& State)

Description

Generate the phi nodes.
