Functions
static BranchInst *	createCondBranch (Value Cond, VPBasicBlock VPBB, VPTransformState &State)
	Create a conditional branch using Cond branching to the successors of VPBB.
static InstructionCost	getCostForIntrinsics (Intrinsic::ID ID, ArrayRef< const VPValue * > Operands, const VPRecipeWithIRFlags &R, ElementCount VF, VPCostContext &Ctx)
	Compute the cost for the intrinsic ID with Operands, produced by R.
static Constant *	getSignedIntOrFpConstant (Type *Ty, int64_t C)
	A helper function that returns an integer or floating-point constant with value C.
static void	scalarizeInstruction (const Instruction Instr, VPReplicateRecipe RepRecipe, const VPLane &Lane, VPTransformState &State)
	A helper function to scalarize a single Instruction in the innermost loop.
static const SCEV *	getAddressAccessSCEV (const VPValue Ptr, ScalarEvolution &SE, const Loop L)
	Returns a SCEV expression for Ptr if it is a pointer computation for which the legacy cost model computes a SCEV expression when computing the address cost.
static bool	isUsedByLoadStoreAddress (const VPUser *V)
	Returns true if V is used as part of the address of another load or store.
static Instruction *	createReverseEVL (IRBuilderBase &Builder, Value Operand, Value EVL, const Twine &Name)
	Use all-true mask for reverse rather than actual mask, as it avoids a dependence w/o affecting the result.
static Value *	createBitOrPointerCast (IRBuilderBase &Builder, Value V, VectorType DstVTy, const DataLayout &DL)
static Value *	interleaveVectors (IRBuilderBase &Builder, ArrayRef< Value * > Vals, const Twine &Name)
	Return a vector containing interleaved elements from multiple smaller input vectors.

◆ getSignedIntOrFpConstant()

Constant * getSignedIntOrFpConstant ( Type * Ty, int64_t C )	static

◆ interleaveVectors()

◆ isUsedByLoadStoreAddress()

◆ scalarizeInstruction()

A helper function to scalarize a single Instruction in the innermost loop.

Generates a sequence of scalar instances for lane Lane. Uses the VPValue operands from RepRecipe instead of Instr's operands.
