Polyglot on the JVM with Graal: One VM for Java, node.js, Ruby, R, and C++!
summary
Graal adds a Java-written JIT and Truffle interpreter framework plus Sulong LLVM support to run many runtimes together; benchmarks show 4–5x speedups for Ruby and R, ≈1.2x for Scala and ~0.9 vs V8 for JS, and large C code runs within ~85% of native. Truffle specializes AST nodes and produces native blobs; SubstrateVM can AOT-link a language into a 61 MB dynamic library with 107 KB startup and exposes near-zero-cost cross-language calls via a polyglot engine.
