A system and method for efficient compilation and invocation of function type calls in a virtual machine (VM), or other runtime environment, and particularly for use in a system that includes a Java Virtual Machine (JVM). The system comprises a virtual machine for executing a software application; a memory space for the application byte code comprising callsites generated using a function type carrier; a bytecode to machine code compiler which performs MethodHandle invocation optimizations; a memory space for the compiled machine code; and a memory space for storing software objects as part of the software application. The system enables carrying the function type from the original MethodHandle to a callsite in the generated bytecode, including maintaining generics information for a function type acquired from a target function, and generating a callsite based on the generics information for the function object invocation. |
