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))
