D.1 Introduction
In the first instance, our compiler’s target is the Java Virtual Machine (JVM), a virtual
byte-code machine. In this appendix, we provide a brief description of the JVM, and then
describe the CLEmitter, a high-level interface for producing the byte code.
D.2 Java Virtual Machine (JVM)
The JVM is an abstract architecture that can have any number of implementations. For
example, Oracle has implemented a Java Run-time Environment (JRE
