VPRecipeBuilder (VPlan &Plan, Loop *OrigLoop, const TargetLibraryInfo *TLI, const TargetTransformInfo *TTI, LoopVectorizationLegality *Legal, LoopVectorizationCostModel &CM, PredicatedScalarEvolution &PSE, VPBuilder &Builder, DenseMap< VPBasicBlock *, VPValue * > &BlockMaskCache)
std::optional< unsigned > getScalingForReduction (const Instruction *ExitInst)
void collectScaledReductions (VFRange &Range)
Find all possible partial reductions in the loop and track all of those that are valid so recipes can be formed later.
VPRecipeBase * tryToCreateWidenRecipe (VPSingleDefRecipe *R, VFRange &Range)
Create and return a widened recipe for R if one can be created within the given VF Range.
VPRecipeBase * tryToCreatePartialReduction (VPInstruction *Reduction, unsigned ScaleFactor)
Create and return a partial reduction recipe for a reduction instruction along with binary operation and reduction phi operands.
void setRecipe (Instruction *I, VPRecipeBase *R)
Set the recipe created for given ingredient.
VPValue * getBlockInMask (VPBasicBlock *VPBB) const
Returns the entry mask for block VPBB or null if the mask is all-true.
VPRecipeBase * getRecipe (Instruction *I)
Return the recipe created for given ingredient.
VPReplicateRecipe * handleReplication (VPInstruction *VPI, VFRange &Range)
Build a VPReplicationRecipe for VPI.
VPValue * getVPValueOrAddLiveIn (Value *V)
void updateBlockMaskCache (DenseMap< VPValue *, VPValue * > &Old2New)

◆ collectScaledReductions()

void VPRecipeBuilder::collectScaledReductions ( VFRange & Range )

◆ getBlockInMask()

◆ getRecipe()

◆ getScalingForReduction()

◆ getVPValueOrAddLiveIn()

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

◆ handleReplication()

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.
