bfc
===
'bfc' is a small, fast, self-contained, optimizing Brainfuck compiler for *nix
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.
Thanks to the unified ABI, adding support for another flavour of *nix only means
changing the syscall numbers. The compiler itself is platform agnostic.
Building
--------
Build dependencies: a C99 compiler +
Runtime dependencies: Linux or OpenBSD
$ git clone https://github.com/pjanouch/bfc.git
$ cd bfc
$ make
To obtain dumps of the intermediate representation, compile with `-DDEBUG`:
$ make CPPFLAGS=-DDEBUG
Usage
-----
$ ./bfc-amd64-linux [INPUT-FILE] [OUTPUT-FILE]
$ ./bfc-amd64-openbsd [INPUT-FILE] [OUTPUT-FILE]
When no input file is specified, standard input is used. Similarly, the default
output filename is `a.out`. After the compilation, the resulting file can be
run on the target platform.
