Which instructions? We specifically didn't add a SIG_ILL handler in the first place to catch mistakes like this so we can fix them. We've got protection in place so such a mistake isn't an XSA any more, but it is still an error we'd like to fix in the emulator. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
