Talking about different instruction sets and compiler scheluding options. Would it be considered a good idea to introduce a sysctl which would contain the maximum mcpu= value for the currently running architechture? This way one could provide with multiple executables and a startup script, in the fashion of: prog.i386 prog.pentium2 prog.pentium3 prog.pentium4 prog.athlon-mp etc... This would ease utilization of various options and probably excersize the CPUs to better extent. Pete > >
