Hi @MarisaKirisame , I have several questions during the learning of AAM, about the advantage of implementing AAM over using the normal Dataflow Analysis framework (like the proposed one above) in the context of Relay. Because I have no experience in Relay at all, I would appreciate it if you can resolve these questions:
1. I was thinking about AAM has the power to unify CFA with a wide range of DFA. It is very tempting but considering the current application area of Relay. I am considering Relay more like a "glue" language that able to perform graph level optimization; which means there won't be any "computationally intensive" piece of code written in Relay. That brings me the question -- what is the benefit of designing a general analysis infrastructure if it won't affect the performance (since the computational heavy part is not written in Relay)? You already have several analyses scattered around. Other than refactoring and giving a better, clean and maintainable developing environment, is there an urgent or short-term benefit to do that? 2. Is there a benefit of adapting CFA in the context of Relay? In this post(#3895) I see you considering an example trying to combine pointer analysis with CFA, is that just for demonstration or that is a real requirement that can help the performance of Relay? My limited Functional Programming experience cannot come up with an example the closure analysis/CFA can help. Could you give an example that CFA will help to improve the performance of Relay code? 3. I am currently still learning AAM. If I understand correctly, even using AAM requires the definition of the abstract domain and the definition of abstract transfer function separately for different analyses. What's more, I currently have doubts about expressing backward analysis and live variable analysis using AAM. I can only find the related post [(mentioned at the very end)](http://pages.cs.wisc.edu/~horwitz/CS704-NOTES/10.ABSTRACT-INTERPRETATION.html) using abstract interpretation to define live variable analysis. This makes me wonder if AAM can subsume the general dataflow monotone framework. Could you give some references for using AAM to implement all kinds of analysis? Great Thanks, and Happy New Year! :) -- You are receiving this because you are subscribed to this thread.
