摘要： A TRANSACTION ABORT instruction is used to abort a transaction that is executing in a computing environment. The TRANSACTION ABORT instruction includes at least one field used to specify a user-defined abort code that indicates the specific reason for aborting the transaction. Based on executing the TRANSACTION ABORT instruction, a condition code is provided that indicates whether re-execution of the transaction is recommended.

摘要： A transaction is initiated via a transaction begin instruction. During execution of the transaction, the transaction may abort. If the transaction aborts, a determination is made as to the type of transaction. Based on the transaction being a first type of transaction, resuming execution at the transaction begin instruction, and based on the transaction being a second type, resuming execution at an instruction following the transaction begin instruction. Regardless of transaction type, resuming execution includes restoring one or more registers specified in the transaction begin instruction and discarding transactional stores. For one type of transaction, the nonconstrained transaction, the resuming includes storing information in a transaction diagnostic block.
摘要翻译： 交易通过交易开始指令启动。 交易执行期间，交易可能会中止。 如果交易中止，则确定交易的类型。 基于事务是第一种类型的事务，在事务开始指令中恢复执行，并且基于事务是第二类型，在事务开始指令之后的指令处恢复执行。 不管交易类型如何，恢复执行包括恢复在事务开始指令中指定的一个或多个寄存器，并丢弃事务存储。 对于一种类型的事务，非约束事务，恢复包括将信息存储在事务诊断块中。

摘要： Program exception conditions cause a transaction to abort and typically result in an interruption in which the operating system obtains control. A program interruption filtering control is provided to selectively present the interrupt. That is, the interrupt from the program exception condition may or may not be presented depending at least on the program interruption filtering control and a transaction class associated with the program exception condition. The program interruption filtering control is provided by a TRANSACTION BEGIN instruction.

摘要： A transaction is initiated within a computing environment, and based on detecting a program event recording event, an interrupt is presented for the transaction. Subsequent to the interrupt, one or more controls are set to inhibit presentation of another interrupt based on detecting another PER event. Thereafter, the transaction is re-executed and PER events detected during execution of the transaction are ignored.

摘要： 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.

摘要： A transaction executing within a computing environment ends prior to completion; i.e., execution is aborted. Pursuant to aborting execution, a hardware transactional execution CPU mode is exited, and one or more of the following is performed: restoring selected registers; committing nontransactional stores on abort; branching to a transaction abort program status word specified location; setting a condition code and/or abort code; and/or preserving diagnostic information.

摘要： Task specific diagnostic controls are provided to facilitate the debugging of certain types of abort conditions. The diagnostic controls may be set to cause transactions to be selectively aborted, allowing a transaction to drive its abort handler routine for testing purposes. The controls include, for instance, a transaction diagnostic scope and a transaction diagnostic control. The transaction diagnostic scope indicates when the transaction diagnostic control is to be applied, and the transaction diagnostic control indicates whether transactions are to selectively aborted.

摘要： Restricted instructions are prohibited from execution within a transaction. There are classes of instructions that are restricted regardless of type of transaction: constrained or nonconstrained. There are instructions only restricted in constrained transactions, and there are instructions that are selectively restricted for given transactions based on controls specified on instructions used to initiate the transactions.
