Our goal in this lecture is to understand compilation from abstract syntax trees to stack machine code

Examples of this:

• javac
• your tool compiler
• compiler from the Pascal Programming Language to pascal UCSD Pascal P-code machine

Source: Java (subset) abstract syntax tree

Target: file containing sequence of instructions for Java Virtual Machine (we will see it in sequel)

• invoked by using the 'java' command
• can inspect it using 'javap -c'
