--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
`s/int/short/` also shows the same issue where GCC stores only in the stack
location that would be the defined side but if GCC would store in the full
stack location, then stp could be used.

Note big-endian has the same issue and still can be using 64bit to store the
full register for these stack slots.
