RTEMS Intel i960 Applications Supplement
As discussed above, the call and callx instructions
automatically save the current contents of the local register
set (R0 through R15). The contents of the local registers will
be restored as part of returning to the application. The
contents of global registers G0 through G7 are not preserved by
RTEMS directives.
