I verified that this is fixed in GCC 3.4, 4.0 as well as on mainline. So this
can be closed.

It looks worse on the mainline:
        stmfd   sp!, {r4, lr}
        mov     r4, r0
        bl      func
        add     r4, r4, r0
        ldrb    r3, [r4, #-4]   @ zero_extendqisi2
        cmp     r3, #97
        bne     .L2
        ldrb    r3, [r4, #-3]   @ zero_extendqisi2
        cmp     r3, #98
        bne     .L2
        ldrb    r3, [r4, #-2]   @ zero_extendqisi2
        cmp     r3, #99
        bne     .L2
        ldrb    r3, [r4, #-1]   @ zero_extendqisi2
        cmp     r3, #100
        movne   r0, #0
        moveq   r0, #1
        ldmfd   sp!, {r4, pc}
.L2:
        mov     r0, #0
        ldmfd   sp!, {r4, pc}
        .size   foo, .-foo

With Mainline today it looks worse -    

     stmfd   sp!, {r4, lr}
        mov     r4, r0
        bl      func
        add     r0, r4, r0
        ldrb    r3, [r0, #-4]   @ zero_extendqisi2
        cmp     r3, #97
        beq     .L6
.L2:
        mov     r0, #0
        ldmfd   sp!, {r4, pc}
.L6:
        ldrb    r3, [r0, #-3]   @ zero_extendqisi2
        cmp     r3, #98
        bne     .L2
        ldrb    r3, [r0, #-2]   @ zero_extendqisi2
        cmp     r3, #99
        bne     .L2
        ldrb    r0, [r0, #-1]   @ zero_extendqisi2
        cmp     r0, #100
        movne   r0, #0
        moveq   r0, #1
        ldmfd   sp!, {r4, pc}
