> This patch is reorganizing the code to split `get_processor_features()` into > multiple helper functions. Details are present in the issue > https://bugs.openjdk.org/browse/JDK-8380448. > It should not change the behavior of any VM flag, except > `UseVectorizedHashCodeIntrinsic`. The earlier code always set > `UseVectorizedHashCodeIntrinsic` to `true` if UseAVX >= 2. That means > specifying `-XX:-UseVectorizedHashCodeIntrinsic` on command line wouldn't > disable use of this intrinsic. This looks like a bug and has been fixed in > this patch. > > --------- > - [x] I confirm that I make this contribution in accordance with the [OpenJDK > Interim AI Policy](https://openjdk.org/legal/ai).
