我正在做一个家庭作业项目，其中涉及一个用编译后的 c 编写的“炸弹”，我必须对其进行逆向工程以提出 5 个字符串，这些字符串将解除炸弹的五个“阶段”中的每一个。我现在被困在第 3 阶段，试图翻译 gdb 为该函数生成的程序集（我相信是 x86，AT&T 语法）。到目前为止，我能够弄清楚的是，它试图将一串六个数字作为用户输入并根据某些标准来判断它们，但这就是我失去它的地方。函数如下（旁边是我尝试的伪代码翻译）。

0x08048895 <phase_3+127>: pop %ebp
0x08048896 <phase_3+128>: ret
我对其中的大部分内容至少有一点（虽然不是很多）信心；我绝对确定是错误的行是当前标记为“魔术”的三行--phase_3+51、phase_3+63 和 phase_3+91（两个语法奇怪的 mov 行和 repnz）。我没有看到太多的语法，我不知道用什么搜索词来查找它们。
对我的尝试有任何一般（和/或严厉）的批评吗？我要出轨的明显地方？显然，既然这是作业，我不需要别人给我答案；我只是想知道我的解释是否普遍合理（这三行意味着我感到困惑）。
非常感谢您的帮助！
