None of them have any branches. (What is signum?) Not so surprising for min and max (and minmax). However, they require a sign extending shift, so that implementation is not possible on all machines. Also, if a branch takes only one cycle (with delay slot), you do not gain anything (in general). -- dik t. winter, cwi, amsterdam, nederland INTERNET : dik@cwi.nl BITNET/EARN: dik@mcvax
