Oh my... Another Brainfuck Compiler - omabfc

OMABFC is a Brainfuck compiler written in C that produces NASM-compatible x64 Linux assembly code.

Usage

OMABFC is a command-line tool. Available options:

--input-file | -i: provides input Brainfuck file (required),
--output-file | -o: provides output file for assembly code (by default code is outputted to stdout),
--version | -v: prints OMABFC version to stdout,
--help | -h: prints help to stdout,
--code-gen | -c: picks a code generator (required),
--tape-size | -t: provides the allocated tape size in bytes (defaults to 1000)

Available code generators

The following code generators are available:

x86_64lin: produces x86_64 Assembly utilizing Linux syscalls,
x86_16dos: produces 16-bit Assembly code that can be built as a DOS .COM executable.

Actually building Brainfuck programs into executables (for x86_64lin)

OMABFC only produces assembly code. This means, that it needs to be manually assembled and linked. The process is fairly simple.

Compile a Brainfuck file: omabfc -i program.bf -o program.asm
Assemble it using nasm: nasm -f elf64 program.asm -o program.o
Link it: ld program.o -o program

And that's it.

Building OMABFC

You need to get CMake and GCC. Go into root directory of the repostiory with a terminal, make a directory called build, go to it and execute cmake .. from it. Now run make all. After the compilation succeeds, omabfc file should appear in the build directory.
