It would be good to keep the v2i64 case I think, it is very similar to v1i64.

Add v2i64 testcase

dmgreen added a comment.Jul 1 2021, 4:09 AM

It's probably good to add them for all the types, even if just for consistency. So for umax/smax/smin too.

dmgreen accepted this revision.Jul 1 2021, 4:09 AM

Otherwise sounds good to me.

This revision is now accepted and ready to land.Jul 1 2021, 4:09 AM
