Combining static and dynamic compilation to remove delinquent loads

A code optimization data processing system configured for combined static and dynamic compilation of program code to remove delinquent loads, the system comprising:

• a static compiler executing in memory of a computer system and configured to statically compile source code into executable code with instrumented sections each being suspected of including a delinquent load, and also into a separate intermediate language representation with annotated portions each corresponding to one of the instrumented sections;
• and,
• a managed run-time also executing in the memory of the computer system and comprising both a monitor and a dynamic compiler, the monitor comprising program code enabled to monitor cache misses for the instrumented sections during execution of instrumented sections, the dynamic compiler comprising program code enabled to dynamically recompile selected ones of the instrumented sections using corresponding ones of the annotated portions of the separate intermediate language representation only after a threshold number of executions of the selected ones of the instrumented sections, each recompilation include a pre-fetch directive at a pre-fetch distances computed to avoid the delinquent load.
