Not yet!
As luck would have it, I discovered a predefined GCC preprocessor
macro named __USER_LABEL_PREFIX__ that has been present since at
least 2.95, if not earlier, and that is just what we have been
looking for!
Armed with this, I have posted a patch that adds this prefix to
the symbols generated by addr2line so that they are similar to
those generated by dladdr or addr2name.awk.
(It seems that my patch has gone to the wrong list - awfully sorry
about this lapse!)
