For your code aarch64 produces:
mod3:
mov w1, 43691
movk w1, 0xaaaa, lsl 16
umull x1, w0, w1
lsr x1, x1, 32
lsr w1, w1, 1
add w1, w1, w1, lsl 1
cmp w0, w1
cset w0, eq
ret
Oh you mean not to produce a%3 followed by == part :). Anyways this code
should go into the middle-end expanders and not be part of match.pd.
