Abstract: Eine Anforderung Load zum Wiederherstellen einer Mehrzahl von konzipierten Registern wird erhalten. Auf der Grundlage des Erhaltens der Anforderung Load werden ein oder mehrere konzipierte Register aus der Mehrzahl der konzipierten Register wiederhergestellt. Das Wiederherstellen verwendet einen Snapshot, der die konzipierten Register physischen Registern zuordnet, um ein oder mehrere physische Register, die aktuell dem einen oder mehreren konzipierten Registern zugewiesen sind, durch ein oder mehrere physische Register des Snapshot zu ersetzen, die dem einen oder mehreren konzipierten Registern entsprechen.

Abstract: A computing environment facility is provided to extend a hold of a cache line in private (or local) cache exclusively after processing a storage operand request. The facility includes determining whether a storage operand request to a storage location shared by multiple processing units of the computing environment is designated hold. In addition, a determination is made whether a state of the corresponding cache line in private cache used for processing the storage operand request is owned exclusively. Based on determining that the storage operand request is designated hold, and that the state of the corresponding cache line in private cache used for processing the storage operand request is owned exclusively, continuing to hold the corresponding cache line in the private cache exclusively after completing processing of the storage operand request. The continuing to hold may include initiating a counter to facilitate the continuing hold for a desired, set interval.

Abstract: Processing of a storage operand request identified as restrained is selectively, temporarily suppressed. The processing includes identifying a storage operand request as restrained, where the identifying includes obtaining, by a processing unit, an access intent instruction indicating an access intent associated with an operand of a next sequential instruction. The access intent indicates usage of the storage operand request is restrained. Further, the method includes determining whether a storage operand request is to a common storage location shared by multiple processing units of a computing environment and is identified restrained, and based on determining that the storage operand request is restrained, then temporarily suppressing requesting access to the common storage location pursuant to the storage operand request.

Abstract: Processing of a storage operand request identified as restrained is selectively, temporarily suppressed. The processing includes determining whether a storage operand request to a common storage location shared by multiple processing units of a computing environment is restrained, and based on determining that the storage operand request is restrained, then temporarily suppressing requesting access to the common storage location pursuant to the storage operand request. The processing unit performing the processing may proceed with processing of the restrained storage operand request, without performing the suppressing, where the processing can be accomplished using cache private to the processing unit. Otherwise the suppressing may continue until an instruction, or operation of an instruction, associated with the storage operand request is next to complete.

Abstract: A guarded storage facility sets up a boundary indicating a range of addresses to be guarded or protected. When a program attempts to access an address in a guarded section defined by the boundary, a guarded storage event occurs. Use of this facility facilitates performance of certain tasks within a computing environment, including storage reclamation.

Abstract: An instruction to perform a conditional branch to an indirectly specified location is executed. A branch address is obtained from a location in memory, the location in memory designated by the instruction. A determination is made,based on a condition code of another instruction, whether a branch is to occur, and a branch to the branch address is performed, based on determining the branch is to occur.

Abstract: Durch einen Computer ausgeführtes Verfahren, um einen Speicherzugriff für eine Ladeanweisung zu umgehen, wobei das Verfahren aufweist:Feststellen einer vorhergesagten Anweisungsadresse (IA), die einer zu der Ladeanweisung gehörenden Lade-IA entspricht, zumindest zum Teil, indem auf eine erste Datenstruktur zugegriffen wird, die mit IAs indexiert wird, welche zu Ladeanweisungen gehören;Nutzen von mindestens einem Teil der vorhergesagten IA, um: i) auf eine zweite Datenstruktur zuzugreifen, um ein erstes physisches Register festzustellen, das einen zu der Ladeanweisung gehörenden Wert speichert, oder um ii) anstelle des Zugriffs auf die zweite Datenstruktur auf eine dritte Datenstruktur zuzugreifen, um den zu der Ladeanweisung gehörenden Wert zu erhalten; undAusführen einer vorhergesagten Ladeoperation als Teil der Ladeanweisung zumindest zum Teil, indem ein zweites physisches Register auf den zu der Ladeanweisung gehörenden Wert gesetzt wird.
