Fixed in GCC12, now  gcc generate optimal codes.

main:
.LFB532:
        .cfi_startproc
        subq    $8, %rsp
        .cfi_def_cfa_offset 16
        movaps  .LC0(%rip), %xmm0
        call    printv
        xorl    %eax, %eax
        addq    $8, %rsp
        .cfi_def_cfa_offset 8
        ret
        .cfi_endproc
.LFE532:
        .size   main, .-main
        .section        .rodata.cst16,"aM",@progbits,16
        .align 16
