--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
As I said earlier, the patch is IMHO wrong and instead ARM/AArch64 should
implement efficient mempcpy in the library.
If not, we should have a target hook whether the target has sane mempcpy or not
and use it at least for cases like this, where using it will allow tail-calling
it, while using memcpy precludes that. And then XFAIL the test on targets with
bad mempcpy implementation.
