I think what happened is that at the time I was writing that patch, I was planning to increase the size of DIERef. But in the end, that did not materialize (we chose to drop the somewhat redundant cu_offset field instead). > > >> Maybe you could give a rough outline of where are you going with this. > > I am trying to reduce `user_id_t` usage as much as possible.

Ok, this part makes sense. It's hard for me to evaluate the rest, as the code your linking to still assumes that the MainCU is stored in the DIERef, which you now say you want to change. Suppose these patches are accepted (let's call them tentatively accepted). What would be the next steps?
