  • Dynamic alias checking with transactional memory
    Patent number: 10216496
    Abstract: An approach to dynamic run-time alias checking comprising creating a main thread and a helper thread, computing an optimized first region of code in a rollback-only transactional memory associated with the main thread checking for one or more alias dependencies in an un-optimized first region of code, responsive to a determination in a predetermined amount of time that no alias dependencies are present in the un-optimized first region of code, committing a transaction and responsive to at least one of a failure to determine results of the check for one or more alias dependencies in the predetermined amount of time and a determination in the predetermined amount of time that alias dependencies are present in the un-optimized first region of code, performing a rollback of the transaction and executing the un-optimized first region of code.
