You need to change those in Output_data_got (the base class) to be virtual.
Then you can override them in Output_data_got_powerpc and use
Output_data_got<size, big_endian>::add_got_entry to call the superclass
method after doing what you need to do first.  Also note that you need to
name the argument type as Output_data_got<size, big_endian>::Got_entry.
You'll probably want to do typedef Output_data_got<size, big_endian> Base;
or suchlike in Output_data_got_powerpc so you can reduce the amount of
typing on the lhs of each :: there.

And, of course, add a test case that notices the failure mode of missing
the reserve_ent call so you can tell whether you got it right.


Thanks,
