    Intel engineers might have been a bit too eager with that feature though, as it seems they enabled it even for older CPUs that don't support it, too. At least I got a ton of '-amxfp16' is not a recognized feature for this target (ignoring feature) since that change and filed this bug report to make them aware of it.

      Yes, typos do happen. Thanks for noticing.
