To clarify, I'm saying that the problem is in moving insn 9 (the store) past
insn 21, not past insn 28. Your simplified dumps in comment #10 support that
(r15 is incremented and decremented, r14 is post-modified; thus, both insn 21
and insn 9 touch memory[r12]). Insn 28 is not relevant to the miscompilation.
