--- Comment #37 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- If a non-general-regs-only function is called from here, it will only preserve d8-d15, and the call-clobbered registers d0-d7 would of course be modified. But is that a problem at all, if the call-clobbered registers are not restored?
