 An alternative may be to have a command hook to load the libs once the=20
 program is running:
 
 define hookpost-run
    sharedlibrary libxxx.so
    enable
 end
 
 This works to some extent in that 'info share' shows the correct libs=20
 loaded, but breakpoints are still 'pending'.
 
 In addition I'm running gdb through kdevelop using the MI interface and=20
 hooks don't seem to work in this case:
 
 define hookpost--exec-run

>Description:
Debugging c++ can be very slow (eg. starting the program & stepping through the code line take >20s).  If I reduce the number of loaded shared libs to only those I'm interested in (eg. 3/50), speed is greatly increased (almost instantaneous).

For a session to be useful with 'set auto-solib-add off' I need to stop the program, load some shared libs, re-enable all break points and continue.  It would be much easier if a  restricted set of shared libs could be loaded automatically by specifying a list or regex.
