    Abstract: A first and a second operand are compared. If they are equal, the contents of register R1+1 are stored at the second-operand location, and the specified CPU or CPUs in the configuration are cleared of all TLB table entries of the designated type formed through the use of the replaced entry in storage, and all lower-level TLB table entries formed through the use of the cleared higher-level TLB table entries. A valid DAT table entry is replaced with a new entry, and the Translation Lookaside Buffer (TLB) is purged of any copies of (at least) the single entry on all CPUs in the configuration. If the first and second operands are unequal, the second operand is loaded at the first-operand location. The comparison result is indicated by the condition code. A method, system and a computer program product are provided.

    Abstract: Executing a Next Instruction Access Intent instruction by a computer. The processor obtains an access intent instruction indicating an access intent. The access intent is associated with an operand of a next sequential instruction. The access intent indicates usage of the operand by one or more instructions subsequent to the next sequential instruction. The computer executes the access intent instruction. The computer obtains the next sequential instruction. The computer executes the next sequential instruction, which comprises based on the access intent, adjusting one or more cache behaviors for the operand of the next sequential instruction.

    Abstract: Ausführen eines Befehls zur Art des Zugriffs auf den nächsten Befehl durch einen Computer. Der Prozessor bezieht einen Zugriffsartbefehl, der eine Zugriffsart angibt. Die Zugriffsart ist einem Operanden eines nächsten sequenziellen Befehls zugehörig. Die Zugriffsart gibt eine Verwendung des Operanden durch einen oder mehrere Befehle im Anschluss an den nächsten sequenziellen Befehl an. Der Computer führt den Zugriffsartbefehl aus. Der Computer bezieht den nächsten sequenziellen Befehl. Der Computer führt den nächsten sequenziellen Befehl aus, was ein Anpassen einer oder mehrerer Cache-Verhaltensweisen für den Operanden des nächsten sequenziellen Befehls auf Grundlage der Zugriffsart aufweist.
