Working compiler for Decaf programming language

Decaf-Compiler

This is a working compiler for Decaf programming language, an object oriented programming language similar to Java but simpler.

Please refer to the following document for more information about decaf language and its lexical and semantic rules: https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-035-computer-language-engineering-spring-2010/projects/MIT6_035S10_decaf.pdf

Usage

• Run src/decafc.py with the input Decaf program as the first argument it will run for both file_name and file_name.decaf
• Note: you can find some sample decaf test files under tests/ directory

Major Dependencies

• PLY:

  PLY is a 100% Python implementation of the common parsing tools lex and yacc developed by David Beazley. For more information and download please see http://www.dabeaz.com/ply/

HOW IT WORKS

• codegen.py will compile test input file to machine readable code. You can see some sample generated files in tests/ directory with .ami extension. These are generated files and shouldn't be modified.

• abstratc syntax tree: You can see all ast definitions under src/ast/ more detailed explanation to come soon.

decaf-compiler's Issues

Fix: broken field_access_expr code generation

field access code generations don't work for the case that arg1 or arg2 are super or this expressions.
