// This file implements the SelectionDAG::LegalizeVectors method.
//
// The vector legalizer looks for vector operations which might need to be
// unrolled and legalizes them. This is a separate step from Legalize because
// unrolling can introduce illegal types. For example, suppose we have an
// scalarized and legalizes them. This is a separate step from Legalize because
// scalarizing can introduce illegal types. For example, suppose we have an
// ISD::SDIV of type v2i64 on x86-32. The type is legal (for example, addition
// on a v2i64 is legal), but ISD::SDIV isn't legal, so we have to unroll the
// operation, which introduces nodes with the illegal type i64 which must be
