篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了配置VM Options查看Java代码的汇编指令相关的知识，希望对你有一定的参考价值。
- 将 hsdis-amd64.dll 和 hsdis-amd64.lib 文件放入 JRE_HOME\\bin\\server 目录下。
- 配置需要查看汇编指令的 Java 入口类的运行配置。
在 Run/Debug Configurations 中编辑如下配置：
VM Options：-server -Xcomp -XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly -XX:CompileCommand=compileonly,*VolatileDemo.*
JRE：E:\\Program Files\\Java\\jdk1.8.0_291\\jre
- Java入口类 VolatileDemo 如下：
package org.example;
public class VolatileDemo
public static boolean stop = false;
public static void main(String[] args) throws InterruptedException
Thread t1 = new Thread(() ->
int i = 0;
while (!stop)
i++;
);
t1.start();
System.out.println("begin start thread");
Thread.sleep(1000);
stop = true;
运行代码，汇编指令打印如下：
"E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\bin\\java.exe" -server -Xcomp -XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly "-XX:CompileCommand=compileonly,*VolatileDemo.*" "-javaagent:E:\\Program Files (x86)\\JetBrains\\IntelliJ IDEA 2020.1\\lib\\idea_rt.jar=53076:E:\\Program Files (x86)\\JetBrains\\IntelliJ IDEA 2020.1\\bin" -Dfile.encoding=UTF-8 -classpath "E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\charsets.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\deploy.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\access-bridge-64.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\cldrdata.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\dnsns.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\jaccess.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\jfxrt.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\localedata.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\nashorn.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\sunec.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\sunjce_provider.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\sunmscapi.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\sunpkcs11.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\ext\\zipfs.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\javaws.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\jce.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\jfr.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\jfxswt.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\jsse.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\management-agent.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\plugin.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\resources.jar;E:\\Program Files\\Java\\jdk1.8.0_291\\jre\\lib\\rt.jar;H:\\IDEAWorkspace\\GuPaoStudyThreadVolatile\\target\\classes" org.example.VolatileDemo
