null is a very overloaded term. What you mean here is simply "ignored". In attempting to confirm/test this, I've found yet another curiosity with instruction length calculations when reordering a rex prefix and legacy prefix. Objdump gets it wrong, but the instruction boundaries according to singlestep are weird. ~Andrew _______________________________________________ Xen-devel mailing list [email protected] https://lists.xenproject.org/mailman/listinfo/xen-devel
