Cache miss saving for speculation load operation

摘要

Compiler optimization methods and systems for preventing delays associated with a speculative load operation on a data when the data is not in the data cache of a processor. A compiler optimizer analyzes various criteria to determine whether a cache miss savings transformation is useful. Depending on the results of the analysis, the load operation and/or the successor operations to the load operation are transferred into a predicated mode of operation to enhance overall system efficiency and execution speed.
