--- Comment #1 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
POWER has (with -mcpu=power10)

        li 9,10
        pli 7,3435973836
        pli 8,3435973837
        rldimi 8,7,32,0
        divdu 9,3,9
        mulhdu 10,3,8
        srdi 10,10,3
        pstd 10,.LANCHOR0+8@pcrel
        mulli 9,9,10
        subf 3,9,3

so this is an actual division that happens there.
