--- Comment #5 from howarth at bromo dot med.uc.edu ---
Checking this issue with current gcc trunk on x86_64 linux, I see differently
handling of sumpartgrid in the emitted assembly...

$ grep sumpartgrid convmix_kfeta.s
    movabsq    $sumpartgrid.3500@GOTOFF, %rax
    movabsq    $sumpartgrid.3500@GOTOFF, %rax
    movabsq    $sumpartgrid.3500@GOTOFF, %rdx
    movabsq    $sumpartgrid.3500@GOTOFF, %rdx
    movabsq    $sumpartgrid.3500@GOTOFF, %rdx
    .local    sumpartgrid.3500
    .largecomm    sumpartgrid.3500,4000000,64

for -mcmodel=medium
