Compiler-Construction-24

This repository contains the implementation of a simple compiler created as part of the COMPILER CONSTRUCTION LAB - 2024, instructed by Sir Laeeq Khan Niazi.

🌟 What does this compiler do?

This compiler takes a source code file (e.g., code.txt) as input and performs the following steps:

1. Tokenization: Breaks the code into meaningful units called tokens.
2. Parsing: Analyzes the tokens to check the syntax and ensures the code follows the grammar rules.
3. Symbol Table Management: Keeps track of all variables, constants, and their attributes (e.g., type, value, scope).
4. Three-Address Code (TAC) Generation: Converts the code into an intermediate representation using three-address code.
5. Intel x86 Assembly Code Generation: Generates assembly code (e.g., output.asm) compatible with the Intel x86 architecture.

This tool helps understand the process behind compiling a program, from high-level code to low-level machine instructions.

💻 How to Compile and Run the Compiler

1. Compile the Compiler

Run the following command to compile the source code of the compiler:

g++ compiler.cpp -o compiler.exe  

2. Run the Compiler

Once compiled, you can use the compiler with the following command:

./compiler.exe code.txt output.asm

In case the above command does not work, run this:

compiler.exe code.txt output.asm

Here:

• code.txt is the input file containing the source code to be compiled.
• output.asm is the generated Intel x86 assembly file.

🛠 Features

• Educational Purpose: Simplified design to help students learn about compiler construction.
• Full Pipeline: Covers key phases of compilation: Lexical Analysis, Syntax Analysis, Semantic Analysis, Intermediate Code Generation, and Assembly Code Generation.
• Output Assembly: Generates Intel x86 assembly code as output, making it easier to see how high-level code maps to low-level instructions.

Feel free to explore the code, test it with your own examples, and learn how a compiler works step by step!
