Was Cinder influenced by hhvm (Facebook's vm for php/hack)? A project that maintains a list of different JIT implementations for programming languages and compares them would be a great way to see what are the different approaches to implementing JITs and which language features make it hard to implement performant JITs. As an aside it is great that the Cinder team is specifically calling out that Cinder is not intended to be used outside of FB. Many people have been burned by lack of community around hhvm.

Definitely influenced. There are people on our team who also worked on hhvm.

I'm afraid there is very little documentation/text on modern production JITters. When I tried finding any text for my MSc I had little success. Does anyone have a suggestion about e.g. .NET 3-tier jitting or similar?

  Here's some good documentation about v8's JIT: https://github.com/thlorenz/v8-perf/blob/master/compiler.md https://github.com/thlorenz/v8-perf/blob/master/compiler.md Note: Never worked on v8, just liked the information here.

  I wrote down "Survey of tiered compilation in JIT implementations" when I researched this: https://github.com/sanxiyn/blog/blob/master/posts/2020-01-03.md https://github.com/sanxiyn/blog/blob/master/posts/2020-01-03...

SOM for example has many implementations with different approaches to compilation http://som-st.github.io http://som-st.github.io.
