bfc is a small, fast, self-contained, optimizing Brainfuck compiler for Linux on Intel x86-64.

Also included are several interpreters in various states of sophistication that document my progress as I was writing this, from the simplest approach to an optimizing JIT compiler.

It’s pretty easy to retarget the compiler, it just means redoing half the work. The compiler itself is platform agnostic.


Build dependencies: a C99 compiler
Runtime dependencies: Linux

$ git clone
$ cd bfc
$ make

To obtain dumps of the intermediate representation, compile with -DDEBUG:



./bfc-amd64-linux [INPUT-FILE] [OUTPUT-FILE]

When no input file is specified, stdin is used. Similarly, the default output filename is a.out. The resulting file can be run on the target platform.
