Is that something different to what vmakarov is doing [1], the work of current MJIT from k0kubun [2] seems to be based on this earlier work. And I believe vmakarov is working on RTL from YARV instructions, and a light weight JIT [3].

If I remember correctly there was a Tracing JIT for CRuby in 2016, but discontinued due to memory consumption

Yup. Quite different. Similar to RuJIT but I’m trying quite a different approach to trace recording and using CraneLift, an optimized code generation backend, rather than using tinycc

Light weight JIT only helps to remove the overhead of GCC etc. Not to be able to inline, constant fold etc. Something like the JRuby IR is required for that.
