An efficient native function interface for Java

We present an efficient and dynamic approach for calling native functions from within Java. Traditionally, programmers use the Java Native Interface (JNI) to call such functions. This paper introduces a new mechanism which we tailored specifically towards calling native functions from Java. We call it the Graal Native Function Interface (GNFI). It is faster than JNI in all relevant cases and more flexible because it avoids the JNI boiler-plate code.
