The invention involves generating persistent code images prior to program execution based on static compilation or dynamic compilation from a previous run, and then, adapting those images during program execution. We describe a method for generating auxiliary information in addition to the executable code that is recorded in the persistent code image. Further, we describe a method for checking the validity of those code images, adapting those images to the new execution context, and generating new executable code to respond to dynamic events, during program execution. Our method allows global interprocedural optimizations to be performed on the program, even if the programming language supports, or requires, dynamic binding. Variants of the method show how one or several of the features of the method may be performed. The invention is particularly useful in the context of implementing Java Virtual Machines, although it can also be used in implementing other programming languages.Other References
