Building a baseline JIT for Lua automatically (2023)

FYI - Mike Pall is back working on LuaJIT.<p>And v3.0 is underway.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;LuaJIT&#x2F;LuaJIT&#x2F;issues&#x2F;1092">https:&#x2F;&#x2F;github.com&#x2F;LuaJIT&#x2F;LuaJIT&#x2F;issues&#x2F;1092</a>

It was a very interesting read, in the context of Python getting a copy-and-patch JIT compiler in the upcoming 3.13 release [1], to understand better the approach.<p>[1] <a href="https:&#x2F;&#x2F;tonybaloney.github.io&#x2F;posts&#x2F;python-gets-a-jit.html" rel="nofollow">https:&#x2F;&#x2F;tonybaloney.github.io&#x2F;posts&#x2F;python-gets-a-jit.html</a>

The last (interpreter only) version mentioned that neither GC nor modules were implemented. Did that change?<p>The JIT work is exciting but even more exciting would be a faster, fully featured interpreter for platforms with runtime code generation constraints (e.g. iOS) for integration into engines like Love

This is a beautiful piece of work. Connecting all the semantic levels is hard work, and this does it elegantly. It goes to show that old-fashioned technology like object files and linkers is still useful, and can still pay off in unexpected ways as part of new technology.

I tried reading this post and it just went way over my head. Anyone have any good resources on background material to even start?

I am using <a href="https:&#x2F;&#x2F;luajit.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;luajit.org&#x2F;</a> in my GCC C++ project.<p>Can I use this faster Lua JIT in my project as a replacement? And if so, how so?<p>The existing luajit doesn&#x27;t do v5.1, so it would be nice to use this newer engine at the newer baseline lua version level.

For those interested, the ACM page for the paper has a good introductory video <a href="https:&#x2F;&#x2F;dl.acm.org&#x2F;doi&#x2F;abs&#x2F;10.1145&#x2F;3485513" rel="nofollow">https:&#x2F;&#x2F;dl.acm.org&#x2F;doi&#x2F;abs&#x2F;10.1145&#x2F;3485513</a>
