Preface

This User's Guide describes how to use the Java Assembler Tools (AsmTools) in your projects. This guide also includes Assembler Tools implementation details and describes the syntax of the JASM and JCOD languages.

AsmTools is a software package containing a collection of tools that you can use to encode and decode a Java class file, without using a Javac compiler. You can use AsmTools to create class files which can not normally be produced by a compiler. These class files can be used during the development process to test the compliance of a Virtual Machine (VM) to its specification.

How This Guide Is Organized

This guide consists of the following sections:

  • Chapter 1 describes the code assembly process in general, and introduces the Asm Tools.

  • Chapter 2 introduces the two types of assemblers/dissassemblers in Asm Tools (JASM, JCoder), and the strengths and applications of each.

  • Chapter 3 introduces the syntax of the JASM and JCoder formats.

  • Appendix A provides a detailed view of the JASM syntax

  • Appendix B provides a detailed view of JCoder syntax
