--- Comment #5 from Renato Golin <renato.golin at linaro.org> ---
The test now produces:

    push    {r4, r5, r6, lr}
    ldrh    r0, [r0]
    mov    r4, r2
    mov    r5, r1
    bl    __aeabi_h2f
    mov    r6, r0
    ldrh    r0, [r5]
    bl    __aeabi_h2f
    mov    r1, r0
    mov    r0, r6
    bl    __aeabi_fadd
    bl    __aeabi_f2h
    strh    r0, [r4]
    pop    {r4, r5, r6, pc}

Which, though a bit ugly, seems correct.
