'bfc' is a small, fast, self-contained, optimizing Brainfuck compiler for *nix
on Intel x86-64. Currently supported targets are Linux and OpenBSD.
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.
Thanks to the unified ABI, adding support for another flavour of *nix only means
changing the syscall numbers. The compiler itself is platform agnostic.
