On trunk with -fno-tree-vrp I see the correct code being generated. 

bs:
        @ Function supports interworking.
        @ args = 0, pretend = 0, frame = 0
        @ frame_needed = 0, uses_anonymous_args = 0
        @ link register save eliminated.
        mvn     r3, #255
        mov     r2, #10
.L2:
        str     r2, [r3], #4
        cmp     r3, #0
        bne     .L2
        bx      lr
