That can be done for non-programmer visible data such as .got
data, but it cannot for 'extern const int x'.
That's what I meant. I was responding to the claim that there are a
lot of .got data. If all we gain are file-level const variables, we
gain extremely little for a lot of overhead.
So I think we do need to find some way to make more effective use of /u.
