    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.
