There's some information about how to collect (and visualize!) JS compilation artifacts in the IRHydra documentation [1]. It's v8 specific, though.

The other writings on that site are worth studying if you want to learn more about how v8 optimizes code [2].

Thanks for the links. Rebuilding V8 is a bit much though. Maybe this is an opportunity for a web service akin to gcc.godbolt.org
