34/* C library -- _exit
35 *
36 * void _exit(int status)
37 * void _Exit(int status)   -- added for SUSv3 standard
38 *
39 * code is return in r0 to system
40 * Same as plain exit, for user who want to define their own exit.
41 *
42 * _Exit() has been implemented as a weak symbol of _exit().
43 * This is the cheapest way to get a duplicate symbol of _exit()
44 * which is all that is required.  To the dynamic linker there
45 * is no difference between a strong and weak symbol.
