As I noted in comment #8 there is a significant speedup from -O2 to -O3 for g++-4.2 (18s -> 5s) With the current g++-4.3 there is no difference between -O2 and -O3 (both 14s) "-fforce-addr" which produced significant speedup does not exist anymore. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33604
