Abstract

A system including a computer storage and a processor is described. The computer storage is configured to identify a stored data as protected. The processor is configured to perform speculative execution. To perform the speculative execution, the processor is configured to determine, in response to the speculative execution of an instruction to read the stored data, whether the stored data is identified as protected. In response to a determination that the stored data attempted to be read during the speculative execution is protected, the processor is configured to disallow during the speculative execution immediate successful completion of the instruction to read the stored data.
