--- Comment #7 from Renato Golin <renato.go...@linaro.org> ---
Trunk generates:
push {r7, lr}
add r7, sp, #0
ldm r0!, {r1, r2}
subs r0, #8
bl bar
pop {r7, pc}
which, while inefficient (the sub is unnecessary with no write-back), looks
correct.
If people feel strongly about reducing code size for that sequence in Thumb1,
please open a new enhancement bug.
