| Zusammenfassung: | An apparatus has processing circuitry to execute a sequence of instructions, an integer storage element to store an integer value for access by the processing circuitry, and a capability storage element for storing a capability for access by the processing circuitry. A capability usage storage is then used to store capability usage information. The processing circuitry is responsive to execution of at least one instruction in the sequence of instructions to generate, in dependence on the capability usage information, a result to be stored in a destination storage element, when the capability usage information identifies a capability state, the result is generated as a capability, and the capability storage element is selected as the destination storage element, and when the capability usage information identifies a non-capability state, the result is generated as an integer value, and the integer storage element is selected as the destination storage element. |
