Hi Edwin, Sorry to bother you. I have a small question for you.

Is it necessary to add type attribute to these INSNs that exist only before split1 pass? These instructions are expanded into the pattern in vector.md after split1 pass and do not reach the sched1 pass at all. If so, I feel that these patterns cannot be added, and it is reasonable to report an error if these INSNs reach sched1 pass. Thanks.
