    Abstract: salvar/ restaurar registradores selecionados em processamento transacional. uma instrução de iniciar transação inicia a execução de uma transação e inclui uma máscara de salvar registrador geral que tem bits os quais, quando definidos, indicam registradores a serem salvos no caso em que a transação é abortada. no início da transação, os conteúdos dos registradores são salvos na memória não acessível para o programa e, se a transação é abortada, os conteúdos salvos são copiados para os registradores.

    Abstract: A conditional instruction end facility is provided that allows completion of an instruction to be delayed. In executing the machine instruction, an operand is obtained, and a determination is made as to whether the operand has a predetermined relationship with respect to a value. Based on determining that the operand does not have the predetermined relationship with respect to the value, the obtaining and the determining are repeated. Based on determining that the operand has the predetermined relationship with respect to the value, execution of the instruction is completed. The obtaining the operand, the determining whether the operand has the predetermined relationship, the based on determining that the operand does not have the predetermined relationship with respect to the value, repeating the obtaining and the determining, and the based on determining that the operand has the predetermined relationship with respect to the value, completing execution of the instruction are performed as part of a single instruction having one operation code.

    Abstract: A non-quiescing key setting facility is provided that enables manipulation of storage keys to be performed without quiescing operations of other processors of a multiprocessor system. With this facility, a storage key, which is accessible by a plurality of processors of the multiprocessor system, is updated absent a quiesce of operations of the plurality of processors. Since the storage key is updated absent quiescing of other operations, the storage key may be observed by a processor as having one value at the start of an operation performed by the processor and a second value at the end of the operation. A mechanism is provided to enable the operation to continue, avoiding a fatal exception.
