BfukC is an optimizing Brainfuck compiler; it reads in a Brainfuck source file and generates an optimized native code executable. Optionally it can run the program directly using its built-in bytecode interpreter.

To produce native code executables BfukC produces LLVM assembly code, which it compiles into optimized binary code using clang. This naturally means that in order to compile native code you need clang installed and in your $PATH.

The compiler uses the Brainfuck-specific optimization techniques mentioned here, except the scanloop and offset optizations. Due to aggressive optimization techniques utilized by the clang LLVM compiler, these are not strictly necessary to produce fast executables but they do shorten compilation times considerably due to Brainfuck's extreme verbosity.

Using the compiler is simple. For example, to compile and run the "Hello, world" example found in example folder:

$ ./bfukc example/hello.bf
$ example/hello
Hello World!

To run the code directly:

$ ./bfukc -b example/hello.bf
Hello World!

BfukC is written in OCaml using Jane Street's Core libraries. To compile it, install ocaml and opam using your favorite package manager and then install the required dependencies:

$ opam install core core_extended

After which you can compile the compiler:

$ corebuild bfukc.native

This will place the binary executable bfukc.native into _build subdirectory (and also symlinks it to current directory).
