simple-compiler

A simple compiler for a simple programming language.

This project was an exercise to better understand compilers and programming language design.

I utilized ChatGPT as a programming partner.

Language

Currently, the language only supports the following:

• Integer data type only
• Variable assignment
• Addition and subtraction operations
• Print operation

Example program

var1 = 5 + 6;
var2 = 2 - 1;
var3 = var1 - var2;
print(var3);

// Prints 10

Getting Started

Build the compiler:

make compiler

Compile a program:

./compiler sample_program.txt sample_program

Run the program:

./sample_program

Note: a temporary file called temp.ll will output to the current directory. This can be safely deleted.

Limitations

The LLVM IR target is hardcoded as arm64-apple-macosx12.0.0.

So I suspect this may have trouble running on other machines.
