摘要
Mechanisms for performing predicated atomic commits based on consistency of watches is provided. These mechanisms include executing, by a thread executing on a processor of the data processing system, an atomic release instruction. A determination is made as to whether a speculative store has been lost, due to an eviction of a memory block to which the speculative store is performed, since a previous atomic release instruction was processed. In response to the speculative store having been lost, invalidating, by the processor, speculative stores that have been performed since the previous atomic release instruction was processed. In addition, the method comprises, in response to the speculative store not having been lost, committing, by the processor, speculative stores that have been performed since the previous atomic release instruction was processed.
