--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Also the other issue is two cmov back-to-back might be bad on x86_64.
In fact on aarch64 we get for sort2_if:
sort2_if(int, int, int*, int*):
cmp w0, w1
csel w4, w0, w1, lt
str w4, [x2]
csel w1, w1, w0, lt
str w1, [x3]
ret
So the question is a cmov better than a branch here, I don't know.
