--- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> ---
The problem is in

        .text
        vpgatherqq      %ymm8, mag01.10849(,%ymm6,8), %ymm5
        .section        .rodata
        .align 16
        .type   mag01.10849, @object
        .size   mag01.10849, 16
mag01.10849:
        .quad   0   
        .quad   2567483615

"mag01.10849(,%ymm6,8)" isn't PC relative.
