attack lab第三题是直接修改了strncmp的参数吧

直接将strncmp的第二个参数sval修改为我们的cookie
使得匹配成功
对把

哦 ， 这个hexmatch已经默认将两个待匹配的字符串设置为相等的直了
中间用sprintf把s改为hex
所以只需要把cookie的hex给rdi，rdi会给rsi

archlab中循环展开优化bug解决

笔记中提到的archlab的Part C部分循环展开优化时，将8次展开和4次展开相结合出现的问题（参考文件labs/archlab/sim/pipe/mncopy.ys）应该是由于跳转的名称出现重复（8次和4词都从ele1开始编号，但是终止语句并不相同）导致问题。经过实验把4次循环的ele名称和之前的区分开来即可通过全部测试并将Average CPE降到8.64。
