We can simply have `0 if target.keys[0] == "cpu" else 1000`. Since we have enabled clflush and it can make the measurement much more accurate, we don't need to set this value to 1000. However, it is only for x86, so we just need to check whether the first target key is for x86 (i.e. `cpu`). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
