The problem is that we decide on the kind of GEP to use only when we vectorize the load/stores. This happens in vectorizeMemoryInstruction. I think that we need to fix this in LoopVectorizationCostModel::getInstructionCost in the load/store switch cases. We have code for checking if the load/store is wide or if it is scalarized.<br>
