Pixel a écrit :
i686 implies "cpuid family >= 6" + cmov

Any LTSP installs is still done on cpuid 5 : there are lots of machinesl like that. Isn't it possible to optimize to i686 while "emulating" cmov?


I don't know how the compilers work, but never understood why they don't create code that can use new instructions AND work without them...
