Even that isn't enough, unless you go with a CPU that doesn't have any branch prediction, speculative execution, or out-of-order execution. I'm not aware of any such processors.
- rowanG077 5y agoThat's exactly what I meant with "how". If an ISA has branch prediction, speculative executions or out-of-order execution this definitely is included on how an ISA handles it's instructions.
