摘要
In a multiprocessor data processing system having a distributed shared memory system, a memory transaction that is a rewind-only transaction (ROT) and that includes one or more transactional memory access instructions and a transactional abort instruction is executed. In response to execution of the one or more transactional memory access instructions, one or more memory accesses to the distributed shared memory system indicated by the one or more transactional memory access instructions are performed. In response to execution of the transactional abort instruction, execution results of the one or more transaction memory access instructions are discarded and control is passed to a fail handler.
