I think the problem may be somewhere else. I got the same xmm0 code

movq %rax, 8(%rdi)

Can you try this with -march=pentium4
pentium4 is not the arch which supports 64bit, it is Nocoa which is a
different
core than the orginal pentium4 which is what is meant by pentium4 here.
Also for x86/64, we have 64bit registers so using the integer registers
is nice.
