------- Comment #9 from steven at gcc dot gnu dot org  2010-01-08 09:34 -------
With "GCC: (GNU) 4.5.0 20100108 (experimental) [trunk revision 155731]" and my
patch for bug 20070 applied, I get the following code:

iterate:
        push    {lr}
        ldr     r3, [r1]
.L6:
        str     r3, [r0]
        sub     r2, r3, #0
        bne     .L5
        b       .L3
.L4:
        ldr     r3, [r3, #8]
        b       .L6
.L5:
        ldr     r1, [r3, #4]
        cmp     r1, #0
        beq     .L4
.L3:
        str     r2, [r0, #12]
        @ sp needed for prologue
        pop     {pc}

Carrot, could you please double-check that this is still correct code?
