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