Java-- Compiler

📖 Description

A Java-- compiler targeting Jasmin/JVM bytecode, developed for the Compilers course at FEUP. The compiler implements the major stages of language processing:

• ANTLR grammar (lexer & parser)
• AST construction & translation
• Symbol table management
• Semantic analysis
• Optimizations (register allocation, constant folding & propagation)
• Code generation to Jasmin

The project demonstrates compiler design principles by translating Java-- (a simplified Java-like language) into executable JVM bytecode through Jasmin.

🚀 How to Run

⚠️ This project does not run as a standalone compiler. To explore its functionality, you should run the test suite using IntelliJ.

1. Open the project in IntelliJ IDEA.

2. Set JDK versions:

   • Go to File > Project Structure > Project
   • Set Project SDK to Java 21
   • Under Gradle Settings, also set the Gradle JVM to Java 21

3. Run the tests:

   • Open the test folder in IntelliJ
   • Right-click and select Run 'All Tests'
   • Alternatively, run individual tests for specific compiler components
