Fusing Method Handle Graphs for Efficient Dynamic JVM Language Implementations
A Method Handle (MH) in JSR 292 (Supporting Dynamically Typed Languages on the JVM) is a typed, directly executable reference to an underlying method, constructor, or field, with optional method type transformations. Multiple inter-connected MHs make up a Method Handle Graph (MHG), which transfers an invocation at a dynamic call site to real method implementations at runtime. Despite benefits that MHGs have for dynamic JVM language implementations, MHGs challenge existing JVM optimization because a) larger MHGs at call sites incur higher graph traversal costs at runtime; and b) JIT expenses, including profiling and compilation of individual MHs, increase along with the number of MHs.
