koturn's brainfuck processor

A brainfuck interpretor/compiler.

Features

• Interpreter, Bytecode interpretor, JIT-compiled code interpretor
• Transpiler to C
• Compiler to executable binary
  • x86 for Windows
  • x64 for Windows
  • x86 for Linux
  • x64 for Linux
  • Armeabi (WIP)

Usage

Execute brainfuck

You can execute brainfuck as following.

$ ./kbf hello.b

The command is equivalent to following command, with option -O1 which means that compile branfuck code to IR-code and execute it.

$ ./kbf hello.b -O1

If you want to execute brainfuck code directory, try following command (very slow).

$ ./kbf hello.b -O1

You can also execute branfuck code with JIT compile (very fast). But currently, this option is available in x86 or x64 environment.

$ ./kbf hello.b -O2

Transpile to C code

You can transpile brainfuck code to C code as following.

$ ./kbf hello.b --target=c -o hello.c

Ofcourse, generated C source file can be compile with C-compiler.

$ gcc hello.b -Wall -Wextra -O2 -o hello
$ ./hello

Compile to native binary

ELF binary

Following example shows that compile brainfuck code to a x64 ELF binary and execute it in x64-Linux environment.

$ ./kbf hello.b --target=elfx64 -o hello
$ ./hello

Generated ELF binary is glibc less binary, use system call only.

EXE binary

Following example shows that compile brainfuck code to a x64 Windows binary and execute it in x64-Windows environment.

$ kbf hello.b --target=winx64 -o hello.exe
$ hello.exe

Future perspective

• Execute with JIT-compile by LLVM
• Generate LLVM-IR
• Fix ARM binary generation
• Use buffer for output characters in Linux ELF binary
