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