--- Comment #3 from Allan Jensen <linux at carewolf dot com> ---
I refer to this:
/* Handle arch= if specified. For priority, set it to be 1 more than
the best instruction set the processor can handle. For instance, if
there is a version for atom and a version for ssse3 (the highest ISA
priority for atom), the atom version must be checked for dispatch
before the ssse3 version. */
