   1 #  One of the rule on restricted sequence is consecutive IU instruction
   2 #       IU: MUL, MAC, MACS, MSUB, MSUBS  (a)
   3 #       IU: MULHXpp, MULX2H, MUL2H      (b)
   4 # This means that instructions in group (a) and in (b) should not be executed
   5 # in IU in consecutive cycles in the order (a)->(b). It does neither prohibit
   6 # executions in the reverse order (b)-> (a) nor consecutive execution of
   7 # group (a)->(a) or (b)->(b)
