State-Changed-Why:
    This has already been fixed (though I can't remember when -- it was some months ago).  Current compiler generates the following at -O2:
    
            @ link register save eliminated.
            ldr     r3, [r1, #4]
            ldr     r2, [r0, #4]
            cmp     r2, r3
            @ lr needed for prologue
            mov     r3, #0
            beq     .L3
    .L2:
            mov     r0, r3
            mov     pc, lr
    .L3:
            ldr     r3, [r0, #0]
            ldr     r1, [r1, #0]
            ands    r3, r3, #7
            movne   r3, #1
            tst     r1, #7
            movne   r2, #0
            moveq   r2, #1
            subs    r3, r3, r2
            movne   r3, #1
            b       .L2
