如何使用GAS内联代码解决问题

Question

我正在尝试编译一小段内联汇编代码，但出现这样的错误：

  

错误：-134的值对于170处的1个字节的字段太大

当我删除足够大的代码部分（复制的“ addl”命令”）时，错误消失了，是否有任何标志或类似的东西使我可以制作尽可能长的asm代码，或者出现问题不是因为长？

代码：

    int x = 1, sm = 0;
    __asm__ __volatile__ (
        "movl $100000000, %%ecx\n\t"
        "movl $0, %%eax\n\t"
        "r:\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "addl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\taddl $0,%%eax\n\t"
        "loop r\n\t"
        "movl %%eax, %0\n\t"
        : "=r"(sm)
        : "r"(x)
        : "%eax", "%ecx"
    );
