Obsolete Repository
This repository is obsolete.
Sulong is now integrated in the Graal repository.
Please open new issues or pull requests directly in the Graal repository.
Existing issues and pull requests can stay on this repository. We will
migrate them as necessary before merging.

4 sourcesNo, but there is a LLVM implementation on top of Java/JVM. :)

Which is much better, because we need more language research with type safe languages, not with C and C++.
In Statically Recompiling NES Games into Native Executables with LLVM and Go (2013)> Has any C compiler closed the loop on that by shipping the full compiler with the program to do runtime optimization?
- The truffleruby "cext" project demonstrated something like this. They interpret and then JIT C on the JVM, and do cross-language inlining and other optimizations.
http://chrisseaton.com/rubytruffle/cext/
The same group is working on compiling LLVM IR on the JVM. Presumably the JVM's tiered runtime optimizations would apply to both of these.
https://github.com/graalvm/sulong
- There are also interactive C(++) "JITs" from CERN and the Julia project. However, as far as I know, they are both method JITs and don't do any trace-based re-JIT/OSR.
https://root.cern.ch/cling and https://github.com/Keno/Cxx.jl
In What Challenges and Trade-Offs Do Optimising Compilers Face?> Thx, does anyone know what is happening on the OMR front? Since it has been very quiet ever since it was first announced.
I don't know if there's a more official channel, but I follow Matthew Gaudet's tweets (@MattStudies). He provides periodic updates and provides links to talks and such.
> Also wondering, for Truffle / GraalVM / SubstrateVM, how far are we from testing in production? I keep thinking TruffleRuby is Nightly / Beta and if i remember correctly, does not run Rails ( yet ) ?
We're not at the point where we recommend anyone run it in production. We do actually run a sizable portion of Rails, but since the DB adapters are all C extensions we can't really run those yet, which practically means we can't run Rails. The distinction is we're able to run with things like the pure Ruby PostgreSQL gem (postgres-pr) and the pure Redis

gem (redis).
We're making some very good progress on our C extension support. We've just recently made a successful HTTPS request running MRI's OpenSSL extension by way of Sulong [1], which is an LLVM bitcode interpreter for Graal.
If you're interested in casually following what we're up to, we now have a Twitter handle (@TruffleRuby). Or, you could always watch the GitHub project [2], since it is open source.
