I just checked to see if this is still a problem. As of r162042, the example
in comment #1 produces the same (bad) output as GCC 4.4.1. However, the example
in comment #4 looks fixed to me, with this output:
test:
push {r0, r1, r2, lr}
mov r3, #0
str r3, [sp, #4]
.L2:
add r0, sp, #4
bl func
ldr r3, [sp, #4]
cmp r3, #12
ble .L2
@ sp needed for prologue
pop {r0, r1, r2, pc}
As it was the latter test case that caused this to be marked as a duplicate of
PR 36758, maybe the original test case is tripping over a different problem and
needs to be re-examined?
