[...] Is it an uncontroversial claim that emulation of CISC instructions should perform better than their native execution, followed by an int3 (as in the simplest working scheme) or boosting (as done by kprobes)? >From my experience with simulators, "simple" software emulation of cpus can be hundreds of times slower or worse than native execution. - FChE -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
