CS451/651 Project 1 (Supporting Simple Operations) Swami Iyer Ob jectives. Become familiar with the CLEmitter, an abstraction for generating JVM bytecode. Extend the base j– language by adding some basic Java operations (on primitive integers) to the language. Supporting these operations requires studying the j– compiler in its entirety, if only cursorily, and then making […]

CS451/651 Project 2 (Scanning) Swami Iyer Ob jectives. 1. Support multiline comments. 2. Support additional tokens (reserved words, operators, and separators). 3. Support long and double literals. In this project, you will only be updating the hand-crafted scanner, which means that the only program files you will be modifying under $j/j–/src/jminusminus are TokenInfo.java and Scanner.java.

CS451/651 Project 3 (Parsing) Swami Iyer Ob jectives. 1. Support long and double basic types. 2. Support operators. 3. Support conditional expression and switch statement. 4. Support do-while and for statements. 5. Support exception handlers. 6. Support interface type declaration. In this project, you will only be supporting the parsing of the above programming constructs

CS451/651 Project 5 (Type Checking and Code Generation) Swami Iyer The goal of this project is to implement type checking and JVM code generation for the Java programming constructs that were introduced in j– as part of Project 3 (Parsing). To compile the j– compiler, run the following command: $ ant clean compile jar To

CS451/651 Project 4 (Scanning and Parsing with JavaCC) Swami Iyer Ob jectives. 1. Support multiline comment. 2. Support long and double basic types. 3. Support operators. 4. Support conditional expression and switch statement. 5. Support do-while and for statements. 6. Support exception handlers. 7. Support interface type declaration. In this project you will only modify
