CS335-Project (Compiler Design)

Instructor: Dr. Swarnendu Biswas

JAVA to x86_64 Compilation Toolchain

Project was completed in 4 milestones:

• Milestone 1: Parser
• Milestone 2: Symbol Table, 3 Address Code
• Milestone 3: Runtime Support
• Milestone 4: x86_64 code gen

Supported Features:

Thankfully, we managed to support all the basic features

• Primitive data types

• Multidimensional arrays.

• Arithmetic operators: +, -, *, /, %, ++, –

• Preincrement, predecrement, postincrement, and postdecrement

• Relational operators: ==, !=, >, <, >=, <=

• Bitwise operators: &, |, ˆ, ˜, ≪, ≫, ≫

• Logical operators: &&, ||, !

• Assignment operators: =, +=, -=, *=, /=, &=

• Ternary operator

• Control flow vila if-else, for, and while

• Methods and method calls, including both static and non-static methods

• Support for recursion

• Support the library function println() for only printing integer

• Support for classes and objects

Whoaaa! we got some optional features:

• Support for array initializer

How to run:

• cd src
• make build (be patient, its not gcc)
• make run input=inputfile.java
• make runasm
• ./a.out

assembly, 3AC , symbol tables and ast tree will be generated in output folder

You can go through the readme of individual milestones in milestoneX/doc
