But %x is still aligned on a 16 byte boundary!  After all, the function's stack
is 16 byte aligned, and %x is in essence the first stack variable.  Try
the prototype of foo1 as follows to ensure that %x is not the first thing on

define void @foo1(i8* byval %z, %struct.sType.alt* byval %x) {

All the movaps go away.
