--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Not allowing the prologue to be moved over clobber-mem-scratch would
pessimize quite a lot of code I think. Here, the problem is that you
really cannot allow any store machine insn inside the loop. Maybe the
loop should be just one RTL insn?
Confirmed btw.
