--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed in GCC 7.0:
f:
movdqa xmm0, XMMWORD PTR .LC0[rip]
mov DWORD PTR c[rip+96], 808464432
movaps XMMWORD PTR c[rip], xmm0
movaps XMMWORD PTR c[rip+16], xmm0
movaps XMMWORD PTR c[rip+32], xmm0
movaps XMMWORD PTR c[rip+48], xmm0
movaps XMMWORD PTR c[rip+64], xmm0
movaps XMMWORD PTR c[rip+80], xmm0
ret
.LC0:
.quad 3472328296227680304
.quad 3472328296227680304
Where GCC 4.7.0 had produced (which is just as ok):
f:
movdqa xmm0, XMMWORD PTR .LC0[rip]
mov BYTE PTR c[rip+96], 48
mov BYTE PTR c[rip+97], 48
movdqa XMMWORD PTR c[rip], xmm0
mov BYTE PTR c[rip+98], 48
mov BYTE PTR c[rip+99], 48
movdqa XMMWORD PTR c[rip+16], xmm0
movdqa XMMWORD PTR c[rip+32], xmm0
movdqa XMMWORD PTR c[rip+48], xmm0
movdqa XMMWORD PTR c[rip+64], xmm0
movdqa XMMWORD PTR c[rip+80], xmm0
