InstructionCost getLegacyCost (Instruction *UI, ElementCount VF) const
Return the cost for UI with VF using the legacy cost model as fallback until computing the cost of all recipes migrates to VPlan.
bool skipCostComputation (Instruction *UI, bool IsVector) const
Return true if the cost for UI shouldn't be computed, e.g.
unsigned getPredBlockCostDivisor (BasicBlock *BB) const
TargetTransformInfo::OperandValueInfo getOperandInfo (VPValue *V) const
Returns the OperandInfo for V, if it is a live-in.
bool isLegacyUniformAfterVectorization (Instruction *I, ElementCount VF) const
Return true if I is considered uniform-after-vectorization in the legacy cost model for VF.
InstructionCost getScalarizationOverhead (Type *ResultTy, ArrayRef< const VPValue * > Operands, ElementCount VF, bool AlwaysIncludeReplicatingR=false)
Estimate the overhead of scalarizing a recipe with result type ResultTy and Operands with VF.

◆ getLegacyCost()

◆ getOperandInfo()

◆ getPredBlockCostDivisor()

◆ getScalarizationOverhead()

Estimate the overhead of scalarizing a recipe with result type ResultTy and Operands with VF.

This is a convenience wrapper for the type-based getScalarizationOverhead API. If AlwaysIncludeReplicatingR is true, always compute the cost of scalarizing replicating operands.
