mibintc edited the summary of this revision.
mibintc added a comment.

Rebased to ToT. It fixes the previous illegal type lowering problems. It also updates the tests to show the functionality in a better way as well as fixes a newly found problem.

Ready for your code review and +1

We think this patch provides basic functionality for the intrinsic, and enhancements can be added in future patches.

Thanks!
