twopy

A Python virtual machine with a JIT compiler based on basic block versioning. Twopy needs python3 to be launched. Twopy is developed and tested on Linux with x86-64 machines.

Building

To fully install Twopy and its dependencies, follow the next steps:

git clone https://github.com/python/cpython.git
cd cpython
git checkout 3.7
./configure --without-pymalloc --with-pydebug --prefix=`pwd`/build
make -j16
./python -m ensurepip
./python -m ensurepip --upgrade
./python -m pip install --upgrade git+https://github.com/Maratyszcza/PeachPy
./python -m pip install capstone
./python -m pip install cffi
cd ..
git clone https://github.com/jpages/twopy.git
cd twopy/

Create the Twopy executable:

make

Now you can run the command ./twopy to execute a Python file.

Running

The simple Fibonacci example:

def fib(n):
    if n<2:
        return 1
    else:
        return fib(n-1) + fib(n-2)

print(fib(40))

This example is already in the repo, to launch Twopy on this example and print the execution time:

./twopy --time tests/fib.py
