hsdis
Hotspot disassembler extracted from openjdk.
Precondition on linux
To build hsdis on linux you need to make sure you have the standard build tools
apt-get install build-essential
Usage
git clone https://github.com/liuzhengyang/hsdis
cd hsdis
tar -zxvf binutils-2.26.tar.gz
make BINUTILS=binutils-2.26 ARCH=amd64
And then copy hsdis build file to the target folder in JDK.
OSX
sudo cp build/macosx-amd64/hsdis-amd64.dylib /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/server/
Java11
sudo cp build/macosx-amd64/hsdis-amd64.dylib /Library/Java/JavaVirtualMachines/jdk-11.0.5.jdk/Contents/Home/lib/server
Linux
sudo cp build/linux-amd64/hsdis-amd64.so /usr/lib/jvm/java-8-oracle/jre/lib/amd64/server/
After that, you could add -XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly in the Java Run Param to see the program's assebmle code.
One Example:
java -XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly -Xcomp -XX:CompileCommand=compileonly,*VolatileTest.main com.io.lzy.VolatileTest
There is already a prebuild hsdis-amd64 for OSX 64 in build/macosx-amd64/macosx-amd64.dylib and for linux in build/linux-amd64/hsdis-amd64.so and was build for/with Unbuntu 16.04
