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
