Other RestrictionsDO SSH,xxxxJSR to (LA) whenever the loop flag (LF) is setJScc to (LA) whenever the loop flag (LF) is setJSCLR to (LA) whenever the loop flag (LF) is setJSSET to (LA) whenever the loop flag (LF) is setNote: Due to pipelining, if an address register (RO-R7, NO-N7, or MO-M7) is changedusing a move-type instruction (LUA, Tcc, MOVE, MOVEC, MOVEM, MOVEP, or parallelmove), the new contents of the destination address register will not be available for useduring the following instruction (Le., there is a single instruction cycle pipeline delay).This restriction also applies to the situation in which the last instruction in a DO loopchanges an address register and the first instruction at the top of the DO loop uses thatsame address register. The top instruction becomes the following instruction becauseof the loop construct. The assembler will generate a warning if this condition is detected.A.9.2 Other DO RestrictionsDue to pipelining, the DO instruction must not be immediately preceded by any of thefollowing instructions:Immediately before DOBCHG LA, LC, SSH, SSL, or SPBCLR LA, LC, SSH, SSL, or SPBSET LA, LC, SSH, SSL, or SPMOVEC to LA, LC, SSH, SSL, or SPMOVEM to LA, LC, SSH, SSL, or SPMOVEP to LA, LC, SSH, SSL, or SPMOVEC from SSHMOVEM from SSHMOVEP from SSHA.9.3 ENDDO RestrictionsDue to pipelining, the ENDDO instruction must not be immediately preceded by any ofthe following instructions:
