This should be enabled with -O3.  From the g++ 3.3.3 manpage...

       -O3 Optimize yet more.  -O3 turns on all optimizations
           specified by -O2 and also turns on the -finline-func­
           tions, -fweb, -funit-at-a-time, -ftracer,
           -funswitch-loops and -frename-registers options.
