--- Comment #2 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
ARMv8-a is the only architecture variant where the CRC extension is optional.
In later variants it is enabled by default; in earlier versions of the
architecture it doesn't exist.
Your report lacks a testcase we can use to examine this more fully.
