    Description

      https://mail.openjdk.java.net/pipermail/hotspot-dev/2020-February/040849.html

      I wish we have a definition of CPU features which specify name and enumeration so that it will be printed automatically, if supported, by VM_Version::get_processor_features(). Counting by hand how many %s I have to add is bug prone. We also need to check that we have enough bits for enumeration.
