Abstract
The present invention provides a method, apparatus, and computer instructions for dynamic intermediate code transformation in a mixed mode compiler. In an exemplary embodiment, an object code compiler of a virtual-machine, such as the just-in-time (JIT) compiler () of a Java virtual machine (JVM), takes loaded classes and compiles these into object code (). A JIT-enabled dynamic instrumentation (JEDI) interface () provides information to an application (e.g., a tool with a GUI), and passes requests for transformation to the JIT () and class-loader (). If loaded, JEDI controls the JIT compiler () to compile and transform the class into object code. Thus, dynamically transformed object code is produced without transformation or re-loading of the loaded classes.
