bf.asm

A simple brainfuck interpreter, written entirely in x86 assembly. Works on Linux x86 and x86_64, and (in theory) DOS-16.

Why

idk lmao

Installation

Prerequisites

• Python 3
• nasm
• CMake >= 3.12
• A functioning C++ compiler (use g++-multilib on Debian-based systems if you want to run the tests)
• dosemu (for running tests)

Building

Build and run tests

./test.sh

This will build for all architectures, and will run some tests on the resulting binaries.

Manually

mkdir build
cd build
cmake -DBITS=64 ..
make
./c-test [some brainfuck file]

Future Work

This is very much a work in progress, especially since my laptop is currently bricked. Here's some notable improvements to make:

• Cleaning up the code
• Giving the binaries more sensible names
• More elegant error handling on DOS
• An overview of the architecture of the project
• Tests for the C library
• More bin tests
• Usage of a stack-like system instead of manual searching for loops
• Trying to decrease the size of the DOS binary to <= 296 bytes (the size of the original)
• Allowing the use of non-static memory for the interpreter's memory area (so it can be used multithreaded!)
