Hi,

done to save the baseregister?
Not that I know of. When I wrote this code, I was faced with the problem
that the optimizer was moving some code using r2 into the prolog before
the __baserel_get_addr call. Therefore, I used this method to make the
call (inserting a fence for optimizing didn't work, either, it would
still move).
I didn't (and still don't) know a lot about the internals of the
compiler, so if you find (or know of) a better way to do that, let me know.
I would suggest, though, to only change it if necessary. At least we
know that this method actually works...
