I while ago I wrote a simple Brainfuck interpreter, JIT and compiler (https://github.com/brianquinlan/brainfuck-jit).

The compiler implements the "Operation offsets" optimization as described in the article. It is actually pretty straightforward. This function converts a map of offset => delta to x86-64 instructions: https://github.com/brianquinlan/brainfuck-jit/blob/master/bf...

and the function following it generates that table.
