commit 0b84d1552a760ccbf0df4e6caa2948cc2a952012
Author: Andrew Cagney <cagney@redhat.com>
Date: Fri Jun 6 11:45:21 2008 -0400
Let DwflDie.getScopes() adjust for module bias.
Instead of trying to remember to write something like
DwflDie.getScopes(address - DwflDie.getBias()), DwflDie handles this
directly. Looking over the code, there were a number of places that
were forgetting to adjust the bias (e.g.., lib.dwfl).
