--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
As mentioned, interrupt attribute will save all the callee saved register if
there is some call as that function is unknown what registers will be used. Yes
GCC could optimize the case where the function is in the same TU and know what
callee registers are in use for that function but I doubt that will save much.
