请教老师在线编程的问题，c中插入汇编语句
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(" IF _data+%0" :"=r"(i):);
asm( " sbi(PORTD,PD2)" :"=r"(i):);
asm( " LCALL delay_%=");
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( "delay_%=:" "ldi %0, $10" :"=r"(k):);
asm( "L3_%=:" "djnz %0, L3_%=":"=r"(k):);
asm( "ret");
}
编译结果：
