请教老师在线编程的问题，c中插入汇编语句

skate6526

模拟波特率，发送data数组的数据，延时什么的都没算，只是看看有波形没有结果编译就有个错。
后面把编译结果也发出来，请高手们看看问题在哪里？语法我按照GCC手册上写的，不知道对不对，谢谢了
void   shortdelay()
{   int i,j,k;
          

        asm(  "L2_%=:"    "ldi %0,$10"         :"=r"(j):);
                               
        asm(  "LP_%=:"          "dec %0"             :"=r"(j):"0"(i));
        asm(  "                      ldi %0,$08"          :"=r"(i):);
                               
        asm(  "L1_%=:"   "ANDl _data+%0,$01"   :"=r"(i):);

        asm( "             ELSE");
                               
        asm( "                           cbi(PORTD,PD2)"     :"=r"(i):);
        asm( "             LCALL delay_%=");
        asm( "     ENDIF");
                                                  
        asm(                   "ror _data+%0"        :"=r"(i):"0"(i));
                               
        asm(                   "DJNZ %0,L1_%="            :"=r"(i):"0"(i));                  
                               
        asm(                   "DJNZ %0,LP_%="       :"=r"(j):"0"(j));

        asm(                   "ret");
}
