Zusammenfassung:An illustrative embodiment of a computer-implemented process for a computer-implemented process for code versioning for enabling transactional memory region promotion receives a portion of candidate source code and outlines the portion of candidate source code received for parallel execution. The computer-implemented process further wraps a critical region with entry and exit routines to enter into a speculation sub-process, wherein the entry and exit routines also gather conflict statistics at runtime. The outlined code portion is executed to determine to use a particular one of multiple loop versions according to the conflict statistics gathered at run time.
