摘要：
Embodiments for dynamically mitigating speculation vulnerabilities are disclosed. In an embodiment, an apparatus includes decode circuitry and execution circuitry coupled to the decode circuitry. The decode circuitry is to decode a single instruction to mitigate vulnerability to a speculative execution attack. The execution circuitry is to be hardened in response to the single instruction.
