1）给定java源代码
// 单例模式（分析volatile关键字是如何禁止指令重排序优化的）
public class Singleton {
private volatile static Singleton instance;
public static Singleton getInstance() {
if(instance == null) {
synchronized (Singleton.class) { // 同步块
if(instance == null) {
instance = new Singleton();
}
}
}
return instance;
}
public static void main(String[] args) {
Singleton.getInstance();
}
}
2）对字节码文件反汇编
Attention）
A1）这里的反汇编与javap的作用不同，javap是获取该文件的字节码指令集（针对java虚拟机），而汇编是获取寄存器指令集（本地CPU支持的指令集）；
A2）我的jdk是 1.8 version，貌似 1.7 不行一样；
2.1）通过java -XX:+PrintAssembly com.jvm.chapter12.Singleton 试图获取汇编代码
2.2）通过 java -XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly com.jvm.chapter12.Singleton 试图获取汇编代码
2.3）很明显，我们这里差一个 动态库文件：hsdis-i386.so： download site: http://kenai.com/projects/base-hsdis/downloads
Attention）
A1）重命名文件：根据自己的os ，找到对应的 Distribution 下载，下载后，还要重命名 为 hsdis-i386.so（访问权限755）
A2）放置位置：将该文件放置到 jdk/jre/lib/i386/ 目录下即可；
2.4）再次获取 汇编代码（bingo）
补充）以下是获取的汇编代码实例
