class VPValue
 

Detailed Description

This class augments a recipe with a set of VPValues defined by the recipe.

It allows recipes to define zero, one or multiple VPValues. A VPDef owns the VPValues it defines and is responsible for deleting its defined values. Single-value VPDefs that also inherit from VPValue must make sure to inherit from VPDef before VPValue.

Member Typedef Documentation

◆ VPRecipeTy

using llvm::VPDef::VPRecipeTy = enum { VPBranchOnMaskSC, VPInstructionSC, VPInterleaveSC, VPReductionSC, VPReplicateSC, VPWidenCallSC, VPWidenGEPSC, VPWidenMemoryInstructionSC, VPWidenSC, VPWidenSelectSC, VPBlendSC, VPFirstOrderRecurrencePHISC, VPWidenPHISC, VPWidenCanonicalIVSC, VPWidenIntOrFpInductionSC, VPPredInstPHISC, VPReductionPHISC, VPFirstPHISC = VPBlendSC, VPLastPHISC = VPReductionPHISC, }

An enumeration for keeping track of the concrete subclass of VPRecipeBase that is actually instantiated.

Values of this enumeration are kept in the SubclassID field of the VPRecipeBase objects. They are used for concrete type identification.

Member Function Documentation

◆ definedValues() [1/2]

ArrayRef<VPValue *> llvm::VPDef::definedValues ( )
inline

Returns an ArrayRef of the values defined by the VPDef.

Definition at line 382 of file VPlanValue.h.

◆ definedValues() [2/2]

ArrayRef<VPValue *> llvm::VPDef::definedValues ( ) const
inline

Returns an ArrayRef of the values defined by the VPDef.

Definition at line 384 of file VPlanValue.h.

◆ dump()

void VPDef::dump ( ) const

Dump the VPDef to stderr (for debugging).

◆ getNumDefinedValues()

unsigned llvm::VPDef::getNumDefinedValues ( ) const
inline

Returns the number of values defined by the VPDef.

◆ getVPDefID()

unsigned llvm::VPDef::getVPDefID ( ) const
inline
Returns
an ID for the concrete type of this object. This is used to implement the classof checks. This should not be used for any other purpose, as the values may change as LLVM evolves.
