Abstract
A system and method for redundant array copy removal in a virtual machine (VM), or other runtime environment, and particularly for use in a system that includes a Java Virtual Machine (JVM). In pointer free languages array copy operations are common and time consuming. Embodiments of the present invention enable the compiler to detect situations where the compiled code can safely use the source array as the destination array without performing any copy operation. By avoiding array copy operations, the performance of the application is improved.
