VPRecipeBuilder()

llvm::VPRecipeBuilder::VPRecipeBuilder ( VPlan & Plan, const TargetLibraryInfo * TLI, LoopVectorizationLegality * Legal, LoopVectorizationCostModel & CM, VPBuilder & Builder, DenseMap< VPBasicBlock *, VPValue * > & BlockMaskCache )

Member Function Documentation

getBlockInMask()

VPValue * llvm::VPRecipeBuilder::getBlockInMask ( VPBasicBlock * VPBB ) const

inline

Returns the entry mask for block VPBB or null if the mask is all-true.

Definition at line 109 of file VPRecipeBuilder.h.

getRecipe()

VPRecipeBase * llvm::VPRecipeBuilder::getRecipe ( Instruction * I )

inline

Return the recipe created for given ingredient.

getVPValueOrAddLiveIn()

VPValue * llvm::VPRecipeBuilder::getVPValueOrAddLiveIn ( Value * V )

inline

Definition at line 127 of file VPRecipeBuilder.h.

References llvm::dyn_cast(), and I.

handleReplication()

VPReplicateRecipe * VPRecipeBuilder::handleReplication	(	VPInstruction *	VPI,
		VFRange &	Range )

Build a VPReplicationRecipe for VPI.

If it is predicated, add the mask as last operand. Range.End may be decreased to ensure same recipe behavior from Range.Start to Range.End.

setRecipe()

void llvm::VPRecipeBuilder::setRecipe ( Instruction * I, VPRecipeBase * R )

inline

Set the recipe created for given ingredient.
