Just hsdis, but maybe the one from Graal that use a better assembler syntax.

I see. That makes sense.BTW, is it hsdis, or is there a new disassembler plugin?

The idea is to bundle jadis with the fast debug VM.

PrintAssembly is available in product builds, too. You'll just need to set -XX:+UnlockDiagnosticVMOptions before setting -XX:+PrintAssembly.

On the other hand, -XX:+PrintOptoAssembly is only available in a debug build.

Just set

Relative question, how can I check a java exec is in fastdebug mode ?




Check "java -version", it will show it is fastdebug.


It seems good (http://openjdk-osx-build.googlecode.com/files/OpenJDK-OSX-8-x64-lambda-fastdebug-jdk-b30-20120420.dmg)





openjdk version "1.8.0-jdk8-b30-x64-lambda-fastdebug"

OpenJDK Runtime Environment (build 1.8.0-jdk8-b30-x64-lambda-fastdebug-20120420)

OpenJDK 64-Bit Server VM (build 24.0-b04, mixed mode)



Thanks




Many thanks, Henry,

now people can use -XX:+PrintAssembly :)
