Hi Max, > It would work if a frame pointer was initialized in the function test, but > it wasn't:
Right, because it unwinds, it needs a valid frame pointer since we no
longer store the stack pointer. So xtensa_frame_pointer_required
should do something like:
if (cfun->machine->accesses_prev_frame || cfun->has_nonlocal_label)
return true;
