getStepVector()

static Value * getStepVector ( Value *  Val, Value *  StartIdx, Value *  Step, Instruction::BinaryOps  BinOp, ElementCount  VF, IRBuilderBase &  Builder  )

static

This function adds (StartIdx * Step, (StartIdx + 1) * Step, (StartIdx + 2) * Step, ...) to each vector element of Val.

The sequence starts at StartIndex. Opcode is relevant for FP induction variable.
