If you want to be pedantic, this isn't from the official documentation (that's the bajillion-paged manual of every instruction), it's from the intrinsics guide here: https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html https://www.intel.com/content/www/us/en/docs/intrinsics-guid... Ideally, it should pull from the same master repository of information, but given my limited experience with how documentation tends to get built, I would be not at all surprised to learn that it's copy-pasted between several different projects, so that bugs in one don't get reflected in others.
