Detailed Description

VPRecipeBase is a base class modeling a sequence of one or more output IR instructions.

Member Typedef Documentation

◆ VPRecipeTy

using llvm::VPRecipeBase::VPRecipeTy = enum { VPBlendSC, VPBranchOnMaskSC, VPInstructionSC, VPInterleaveSC, VPPredInstPHISC, VPReplicateSC, VPWidenIntOrFpInductionSC, VPWidenMemoryInstructionSC, VPWidenPHISC, VPWidenSC, }

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

◆ eraseFromParent()

iplist< VPRecipeBase >::iterator VPRecipeBase::eraseFromParent ( )

This method unlinks 'this' from the containing basic block and deletes it.

Returns: an iterator pointing to the element after the erased one

◆ execute()

virtual void llvm::VPRecipeBase::execute ( struct VPTransformState & State )

pure virtual

The method which generates the output IR instructions that correspond to this VPRecipe, thereby "executing" the VPlan.

Implemented in llvm::VPWidenMemoryInstructionRecipe, llvm::VPPredInstPHIRecipe, llvm::VPBranchOnMaskRecipe, llvm::VPReplicateRecipe, llvm::VPInterleaveRecipe, llvm::VPBlendRecipe, llvm::VPWidenPHIRecipe, llvm::VPWidenIntOrFpInductionRecipe, llvm::VPWidenRecipe, and llvm::VPInstruction.

◆ getParent() [1/2]

VPBasicBlock* llvm::VPRecipeBase::getParent ( )

inline

Returns: the VPBasicBlock which this VPRecipe belongs to.

Definition at line 587 of file VPlan.h.

Referenced by insertBefore().

◆ getParent() [2/2]

const VPBasicBlock* llvm::VPRecipeBase::getParent ( ) const

inline

Definition at line 588 of file VPlan.h.

References Indent, llvm::RISCVFenceField::O, and print().

◆ getVPRecipeID()

unsigned llvm::VPRecipeBase::getVPRecipeID ( ) 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.
