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.
