#  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)
