With -fno-common,
arm LE produces:
    movw    r3, #:lower16:.LANCHOR0
    movt    r3, #:upper16:.LANCHOR0
    ldmia    r3, {r0, r3}
    add    r0, r0, r3
    bx    lr

AARCH64 produces:
    adrp    x1, .LANCHOR0
    add    x1, x1, :lo12:.LANCHOR0
    ldr    w2, [x1]
    ldr    w0, [x1,4]
    add    w0, w2, w0
    ret
