@hfinkel Thank you so much for the suggestion. I reimplemented the patch based on your suggestion and I hope this implementation is cleaner than the previous one.
So far, the patch supporting only i32 to i64 zero-entensions. I will support other conversions such as i1 case if I found common patterns.
