Comment (by js):
Oh, forgot to mention: Our debugger shows an %rsp that ends in 0x8 and the
movdqa stores its value in (%rsp). When I look at the %rsp in _start, it
ends in 0x0, according to the debugger. IMHO it should be the other way
around: When you enter a function, the %rsp should end in 0x8. The first
thing the prologue will do is pushing %rbq, so that after the push the
alignment will end 0x0 and thus be correct.
