On the trunk we get:
movdqa xmm0, XMMWORD PTR _ZL5array[rip]
movdqa xmm1, XMMWORD PTR _ZL5array[rip+16]
movdqa xmm2, XMMWORD PTR _ZL5array[rip+32]
movdqa xmm3, XMMWORD PTR _ZL5array[rip+48]
movdqa xmm4, XMMWORD PTR _ZL5array[rip+64]
movdqa xmm5, XMMWORD PTR _ZL5array[rip+80]
movups XMMWORD PTR [rdi], xmm0
movdqa xmm6, XMMWORD PTR _ZL5array[rip+96]
movdqa xmm7, XMMWORD PTR _ZL5array[rip+112]
movups XMMWORD PTR [rdi+16], xmm1
movups XMMWORD PTR [rdi+32], xmm2
movups XMMWORD PTR [rdi+48], xmm3
movups XMMWORD PTR [rdi+320], xmm4
movups XMMWORD PTR [rdi+336], xmm5
movups XMMWORD PTR [rdi+352], xmm6
movups XMMWORD PTR [rdi+368], xmm7
Even with -mavx which I had assumed would use the ymm registers.
