----------------
This looks to be adding RDRAND to SLM. Whether that's correct or not, that's a functional change which should not be part of this patch.


================

+  FeatureSlowUAMem16,
+  FeatureSSSE3,
+  FeatureSlowBTMem,
----------------
Should SSSE3 be part of AtomValues instead? The rest of these are uarch details, but that one is a real feature and should be with the other features.
