--- Comment #4 from Segher Boessenkool <segher at gcc dot gnu.org> ---
power9.md has

(define_insn_reservation "power9-store" 0

whereas pretty much everything else has a non-zero number here.  This number
is only for true dependences, so read-after-write, so 0 does not make super
much sense anyway.

Assigning this to Pat.  Pat, feel free to kick it back to me, or to whoever
else you want ;-)
