Do you mean checking if peeling aligns >= 2 refs for sure? (i.e. with a known misalignment) Or the same as currently via STMT_VINFO_SAME_ALIGN_REFS just for stores and .length() >= 2? Is checking via vect_peeling_hash_choose_best_peeling () too costly or simply unnecessary if we already know the costs for aligned and unaligned are the same? Regards Robin
