Intel SA-00145: Lazy FP State Restore
Serious question - should we considering speculative cpu execution to be A Bad Idea (tm) and move on from it (since these problems keep coming up), or is the thought that we more or less have been gaining performance on the back on incorrectly written software (which does not take these speculative execution edge cases into account), and the only forward is patching?<p>I guess a another question I have is can we win the performance back through fixes on the cpu or will speculative execution always be insecure and thus need patching in software?<p><i></i> Try as I might, I am not a CPU person.
