请问在 ArchLab 里，怎么以 GUI mode 来执行指令，我卡在了设置 DISPLAY 环境变量上，望回复
Data Lab的bits.c文件中使用了大量大整数常量
要求是：Integer constants 0 through 255 (0xFF), inclusive. You are not allowed to use big constants such as 0xffffffff.
你好,想问下这个环境怎么搭建呀!
如果可以的话,请教教我
建议阅读书籍
不能用%r15是因为Y86-64没有%r15寄存器
可以把所有 lab 的代码上传吗？
我最近也在读 CSAPP 第三版，但是我没有账号，无法下载 lab 的代码。你可以把所有 lab 的代码上传吗？
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
bomblab_phase4_func4
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。
