--- Comment #4 from Robin Dapp <rdapp at gcc dot gnu.org> --- Heh, it's even worse. We don't actually set the mode alignment of VLS modes properly and just use their full size. So when we adjust an address like in memcpy, the new MEM has 128-bit alignment by default instead of what the input mem indicated.
