LuaJIT has great performance through the C FFI. It’s more that traditional JITs can’t optimize across FFI boundaries. Hopefully Chris will correct me if I’m full of shit. There are other approaches which can work too, like compiling C to LLVM IR using Clang so a function can be inlined by an LLVM based JIT at runtime.
