c++ 使用asmjit

• asmjit github
• asmjit home

1. 下载源码

在github下载源码放在"desctop/asmjit-master"

2. 使用cmake生成构建系统

> Desktop\asmjit-master> cmake CMakeLists.txt

3. 使用vs2019编译

使用vs2019打开"asmjit.sln"，使用release x64打包

打包后会将"asmjit.dll"和"asmjit.lib"输出到"desctop/asmjit-master/Release"

4. 在项目中使用asmjit

1. 设置"asmjit"头文件位置，通常是"Desktop\asmjit-master\src"

2. 设置"asmjit.lib"位置
   

3. 设置"asmjit.dll"位置
   

5. 拷贝官网demo到main.cpp，然后运行

MessageBoxA Example

#include <iostream>
#include <Windows.h>
#include <asmjit/asmjit.h>

using namespace asmjit;

typedef int (*Func)(void);

int main(int argc, char* argv[]) {
  JitRuntime rt;

  CodeHolder code;
  code.init(rt.environment());
  x86::Assembler a(&code);
  
  a.push(x86::rbp);
  a.mov(x86::rbp, x86::rsp);
  
  a.sub(x86::rsp, 32);
  a.mov(x86::rcx, 0);
  a.mov(x86::rdx, "body");
  a.mov(x86::r8, "title");
  a.mov(x86::r9, 3);
  a.call(MessageBoxA);
  a.add(x86::rsp, 32);

  a.mov(x86::rsp, x86::rbp);
  a.pop(x86::rbp);
  a.ret();

  Func fn;
  Error err = rt.add(&fn, &code);
  if (err) return 1;
  printf("%d\n", fn());

  rt.release(fn);
  return 0;
}

如果你要同时编译asmjit和asmtk，将两个放在同级目录，asmtk的cmakelist会去"../asmjit/"找asmjit的cmakelist
