In 4.3 and above, you can set the CPUTYPE variable to compile your system with appropriate options in you will be using and compiling this build only on machines of the same type. You can choose from options including p2, p3, and pentiumpro for the various i686 class CPUs. See /etc/defaults/make.conf for the list of choices. This will add appropriate CFLAGS to all compiles and will enable processor-specific assemably where it is both available and appropriatly configured. In the base system this only works for OpenSSL, but support is being expanded in ports as well. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
