--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
With -funroll-loops on the trunk for the aarch64 target, I get no loop any
more:
bar and seems like good code:
.LFB0:
.cfi_startproc
and w1, w1, 65535
mov w2, 8193
tst w0, 2
eor w3, w1, w2
csel w4, w1, w3, eq
tst w0, 4
eor w5, w4, w2
and w6, w5, 65535
csel w7, w6, w4, ne
tst w0, 8
eor w0, w7, w2
and w8, w0, 65535
csel w0, w8, w7, ne
ret
Oh I recongize this loop too, it is from coremark.
