getScalarizationOverhead()
Hi, I wonder why getScalarizationOverhead() does not take into account the number of operands of the instruction? This should influence the number of extracts needed, so instead of Scalarization cost = NumEls * (insert + extract) it would be better to do Scalarization cost = NumEls * (insert + (extract * numOperands)) / Jonas
