Methods and apparatus are provided for enhanced instruction handling in processing environments. A program reference may be associated with one or more program modules. The program modules may be loaded into local memory and information, such as code or data, may be obtained from the program modules based on the program reference. New program modules can be formed based on existing program modules. Generating direct references within a program module and avoiding indirect references between program modules can optimize the new program modules. A program module may be preloaded in the local memory based upon an insertion point. The insertion point can be determined statistically. The invention is particularly beneficial for multiprocessor systems having limited amounts of memory. |
