Why didn't you use gcc's intrinsic: http://gcc.gnu.org/onlinedocs/gcc-4.4.2/gcc/Other-Builtins.html#index-g_t_005f_005fbuiltin_005fclz-2895<br />And since I didn't see how it's used: how do you deal with the case where input == 0? BSR (and the intrinsic) explicitly state the result is then undefined.
