InsCounter

Introduction

This is an instrument used for counting the total number of execute bytecode instructions.

Input

Your Jar File.

Output

Edited Jar file that can output the numebr of execute bytecode instructions.

Library

It is based on ASM.

Usage

Step 1

Put InsnCounter.jar, asm-all-5.0.3.jar, and the jar file you want to count in the same directory.

For example: Here we have: InsnCounter.jar, asm-all-5.0.3.jar, Hello.jar in one directory.

Step 2

Inside the directory, run

Java -jar InsnCounter.jar <Your Jar file>

For here, we run

Java -jar InsnCounter.jar Hello.jar

Step 3

You will find that there is a new folder called "outJar" created under the directory. All the edited bytecode are shown there.

To build artifacts, just chang your directory to "outJar" and run jar command.

For here, we run:

cd outJar

jar cf newHello.jar com

Then we get the goal.
