--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For AARCH64 GCC does a much better job:
foo:
stp x29, x30, [sp, -32]!
add x29, sp, 0
ldrb w1, [x29,28]
lsr w2, w0, 2
bfi w1, w2, 2, 2
lsr w0, w0, 6
bfi w1, w0, 6, 1
add x0, x29, 24
strb w1, [x29,28]
bl bar
But there is still some things missing but it is still a much better job than
what happens on x86.
