Hi! it's a bit hard to know what what to suggest to start with. Would you be interested in setting up a Zoom call (eg next week, some evening CET) to discuss a bit your concrete plans and timeline? (I for one would be somewhat worried whether all that you are describing is doable in the timing c

Hi, so to update you both I have decided to pursue this project after all, I'm very excited to work on PyPy. To reiterate my objective, I'll be trying to formulate a way to augment the JIT optimiser to expose enough information such that more advanced optimisations can be implemented, with Poly

Thanks both of you for getting back to me, these definitely seem like problems worth thinking about first. Looking into it, there has actually been some research already on implementing Polyhedral optimisations in a JIT optimiser, specifically in JavaScript. It's paper (http://impact.gforge.inr
