Linux hook 部分函数崩溃，例如close 最简单的在自定义hook函数里面return 原函数 报段错误核心已存储

master分支在macOS Monterey 12.0.1 Intel环境下hook C++方法失败了，同时dev分支在macOS 12.0.1编译失败

3

目前测试出了两个问题： 1. master分支在macOS Monterey 12.0.1 Intel 环境下hook C++方法失败了 2. dev分支在macOS 12.0.1编译失败（不确定dev分支是否已经修复hook C++ 方法，没编译出来，无法测试）

Linux x86_64下pxor xmm0,xmm0导致DobbyHook unimplemented code abort

在对开头有pxor xmm0,xmm0这样汇编指令的函数进行hook时，会出现DobbyHook unimplemented code abort的问题。 要hook的函数的汇编如下 ``` pwndbg> x/16i 0x7ffff7a538f0 0x7ffff7a538f0 : push rbp 0x7ffff7a538f1 : pxor xmm0,xmm0 0x7ffff7a538f5 : mov rbp,rsp 0x7ffff7a538f8 : push r15 0x7ffff7a538fa : push r14...
