BFVM by matthilde

This is an optimized brainfuck interpreter that uses a VM with an instruction
set designed to run brainfuck.
The assembler includes a few optimizations to improve speed greatly.
And it now includes a Just-In-Time compiler (JIT) that is even faster.

NOTE: The JIT has been designed to run on x86-64 CPUs, if you have something
      else, the JIT will not work.
      And since it uses mmap, it only works for Linux.
      However nothing prevents you to port this interpreter, if it's even worth
      it...

 Look, I don't care about this piece of software. Do whatever you want with it
 tbh, belongs to public domain i guess
