One embodiment of the present invention provides a system that gathers code usage information to facilitate removing compiled code that has not been recently used. This method operates in a mixed-mode system that supports execution of both compiled code and interpreter code. During operation, the system gathers usage information for compiled methods within an application while the application is executing. Next, the system identifies compiled methods to be removed based on this usage information, and removes identified compiled methods so that interpreter code is executed for the compiled methods instead of compiled code. In this way, the system frees up the memory space used to store the compiled methods.
