+    * Code: Generic 64-bit unary operation. Provide an "instr" variable and a
+    *       preinstr variable that together specify an instruction that
+    *       performs, for example, "%xmm0 = op %xmm1".
+    *
+    * For:  neg-double, neg-long, not-long
+    *
+    * Description: Perform the identified unary operation on the source
+    *              register, storing the result in the destination register
+    *
+    * Format: B|A|op (12x)
+    *
+    * Syntax: op vA, vB
