Abstract

This paper presents a technique for backpatching instructions in an SMP environment. This technique is used by the Jalapeno virtual machine to support dynamic class loading in Java. There is a small runtime overhead the first time a backpatch site is executed. Thereafter, it executes at the same speed as equivalent sites not requiring back-patching.
