--- Comment #4 from Segher Boessenkool <segher at gcc dot gnu.org> ---
It's not fixed. On trunk we get:
===
flush_dcache_range:
rlwinm 3,3,0,0,27
addi 4,4,15
subf 4,3,4
srwi. 9,4,4
beq 0,.L1
slwi 9,9,4
addi 9,9,-16
srwi 9,9,4
addi 9,9,1
mtctr 9
.p2align 4,,15
.L3:
dcbf 0, 3
addi 3,3,16
bdnz .L3
sync
.L1:
blr
===
(-m32, edited a bit).
The slwi/addi/srwi/addi is unnecessary.
