Member Function Documentation

getRecipe()

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

inline

Return the recipe created for given ingredient.

Definition at line 101 of file VPRecipeBuilder.h.

References assert(), and I.

getVPValueOrAddLiveIn()

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

inline

Definition at line 114 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.

tryToCreateWidenNonPhiRecipe()

VPRecipeBase * VPRecipeBuilder::tryToCreateWidenNonPhiRecipe	(	VPSingleDefRecipe *	R,
		VFRange &	Range )

Create and return a widened recipe for a non-phi recipe R if one can be created within the given VF Range.
