SALVAGING HARDWARE TRANSACTIONS |
| 摘要 |
A transactional memory system salvages a partially executed hardware transaction. A processor of the transactional memory system saves state information in a first code region of a first hardware transaction. The processor executes an about-to-fail handler, the about-to-fail handler using the saved state information to determine whether the first hardware transaction is to be salvaged or to be aborted. The processor executing the about-to-fail handler, based on the transaction being to be salvaged, uses the saved state information to determine what portion of the first hardware transaction to salvage. |

1. A computer system for salvaging a partially executed hardware transaction, the computer system comprising:
a memory; and a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising: saving, by a processor, state information in a first code region of a first hardware transaction; executing, by the processor, an about-to-fail handler, the about-to-fail handler using the saved state information to determine whether the first hardware transaction is to be salvaged or to be aborted; and based on the transaction being to be salvaged, using, by the processor executing the about-to-fail handler, the saved state information to determine what portion of the first hardware transaction to salvage. |
