The last two weeks were slow. But implemented very important features. I am currently busy with my college examinations, and could not give much time here.
I have implemneted ASR pass for BindPython ABI. BindPython ABI allows calling into CPython code from LPython. Previously BindPython was exclusively implemented on the C backend. The advantage of implementing the ASR pass for BindPython is that all the backends will support out of the box, provided it already supports BindC ABI. Most if not all backends already support BindC ABI. The pass generates the body of the declared BindPython function. The pass takes care of the necessary type conversions from the CPython type to the native type and from the native type to the CPython type. The pass also takes care of loading the CPython module and getting a reference to the function that needs to be called.
Type conversions of primitive types (i.e. int, float, bool, and str) have been implemented and merged. I have an open PR for type conversions of aggregate type (i.e. list, tuple, dict, and set).
The previous implementation of BindPython ABI in the C backend conversions LPython arrays into numpy arrays and passing numpy arrays to CPython functions. In the coming week, I will be working on conversions of LPython arrays to numpy arrays for the same.
