-/* The GCC global register variable extension is used to reserve some
-   host registers for use by generated code.  However only the core parts of
-   the translation engine are compiled with these settings.  We must manually
-   save/restore these registers when called from regular code.
-   It is not sufficient to save/restore T0 et. al. as these may be declared
-   with a datatype smaller than the actual register.  */
