Abstract
The present invention provides a system and method for runtime updating of hints in program instructions. The invention also provides for programs of instructions that include hint performance data. Also, the invention provides an instruction cache that modifies hints and writes them back. As runtime hint updates are stored in instructions, the impact of the updates is not limited by the limited memory capacity local to a processor. Also, there is no conflict between hardware and software hints, as they can share a common encoding in the program instructions.
