@dexonsmith I'm really struggling to get the uselistorder support working with this patch. The key change here is that constant expressions are materialized on first use, rather than all at once when parsing the constant block. I think I fixed the case where constant expressions are referenced by instructions correctly, but despite trying different variants for a few hours, I just can't figure out how to handle expressions in global initializers correctly. Do you have any pointers?
