Abstract
A data processing apparatus comprises an instruction decoder and processing circuitry. The processing circuitry is configured to perform a load-with-substitution operation in response to the instruction decoder decoding a load-with-substitution instruction specifying an address and a destination register. In the load-with-substitution operation, the processing circuitry is configured to issue a request to obtain target data corresponding to the address from one or more caches. In response to the request hitting in a given cache belonging to a subset of the one or more caches, the processing circuitry is configured to provide to the destination register of the load-with-substitution instruction the target data obtained from the given cache. In response to the request missing in each cache belonging to the subset of the one or more caches, the processing circuitry is configured to provide a substitute value as the correct architectural result corresponding to the destination register of the load-with-substitution instruction.
