Abstract
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 state information useable to determine whether the first hardware transaction is to be salvaged or to be aborted. The processor detects an about to fail condition in the first code region of the first hardware transaction. The processor, based on the detecting, 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.
