Abstract
A system and method for efficient string concatenation in a virtual machine (VM), or other runtime environment, and particularly for use in a system that includes a Java Virtual Machine (JVM). An embodiment improves the performance of string concatenation significantly by analysing the string concatenation chains during bytecode compilation and replacing the dynamic string concatenation code with fixed size structures without bounds checks or locks. The resulting code is also more suitable for inlining.
