No. Please see NOTE part of the description. AArch64 doesn't cost ccmp
currently. It will be fixed by a seperate patch later. The testcase is
thus marked as XFAIL.

I'd prefer to do things in the right order. Your patch is approved, butplease commit only after you can remove the xfail from the testcase.
