+;; issue	describes the issue pipeline.
+;; alu		describes the Integer unit
+;; fpu		describes the FP unit

+;; The fp unit is out of order execution unit with register renaming.
+;; There is also memory management unit and execution pipeline for
+;; load/store operations.  We ignore it and difference between insns
