I don't think this patch clashes with what I was trying, so please go ahead. I was looking at patches to remove the globalness of vinfo_for_stmt, mostly by avoiding it wherever possible and using stmt_info instead of gimple *. That's quite a lot of churn but leaves very few vinfo_for_stmts left. It also included an attempt to clean up how we handle getting the vector versions of operands. Thanks, Richard
