bf2elf

• Ever had the dream of compiling brainfuck down to native machine code?
• Ever wanted to have a way to use brainfuck to achieve something?

If you answered yes to any of the previous questions, fear not, you are in the right place.

bf2elf is a compiler/interpreter for the brainfuck language. It allows you to test your code with the built-in interpreter and then compile it and link it with the rest of your project.

With this tool, brainfuck compiles down to cough relatively unoptimized cough x86_64 assembly which using nasm can be compiled down to an object file to link with other code.

Usage

This compiler exports one function containing all the compiled brainfuck code. The name of this symbol is specified with the -s/--symbol parameter. For an example of how to call this function from C see tester.c and include/test.h

See the makefile for more.

Notes

You need to have nasm installed.

Only 64-bit mode supported. No puny 32-bit computing here.

Unlike the interpreter, the compiler does not support the . and , operators of the language, totally not because I don't want to have to deal with memory management in pure x86 assembly, but because I don't think it would be that useful, plus this kind of thing can be done before calling the brainfuck code through the memory block the caller has to allocate.
