--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is literally just measuring memset times of a small structure.

-mtune=intel changes the timings too.
Doing -mstringop-strategy=libcall also changes the timing to the point where
they are about the same as clang.

So this is a target issue and not a middle-end.

You need to do timings on many more processors to have the -mtune=generic
changed.
