Sulong

Sulong is a high-performance LLVM bitcode runtime built on theGraalVM by Oracle Labs.

Sulong is written in Java and uses the Truffle language implementation framework and Graal as a dynamic compiler.

With Sulong you can execute programming languages that can be transformed to LLVM bitcode on GraalVM. This includes languages like C/C++, Fortran, and others.
