                     "cmpxchg16b\t$dst", []>,
-                    TB, Requires<[HasCmpxchg16b,In64BitMode]>;
+                    TB, Requires<[HasCX16,In64BitMode]>;
 } // SchedRW, mayLoad, mayStore, hasSideEffects
----------------
I used hasCX16 here instead of useCMPXCHG16B since we have to use In64BitMode explicitly any way for the assembler.
