| # 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) |
