It's not useful for CPython, since it's based on a loop which evaluates a bytecode at the time.

You have to rewrite the virtual machine implementing a JIT compiler that generates Thumb-EE instructions. But it's a big effort, since ceval.c works in a completely different manner. I don't know if a form of JIT will be implemented in future CPython implementations, but if a step in this direction will be made, writing a back-end that uses Thumb-EE will be much easier.

It is beginning to sound like PyPy may be a more appropriate platform for this experimentation than CPython.

Cheers, Nick.
