Btw. Is DSP stack always fixed size like Hatari code would indicate:
---- dsp_core.h ----
struct dsp_core_s {
....
        /* stack[0=ssh], stack[1=ssl] */
        Uint16  stack[2][16];
--------------------
?

And what happens when DSP subroutine call hierarchy gets too deep,
does the DSP stack just wrap around & overwrite previous return
addresses, or does it do something else?
