21 /* The hell below need some explanations. For each symbolic number, we need to
22 * define it with TRACE_DEFINE_ENUM() and in a list for __print_symbolic.
23 *
24 * 1. Define a new macro that call TRACE_DEFINE_ENUM():
25 *
26 * #define xxx_name(sym) TRACE_DEFINE_ENUM(sym);
27 *
28 * 2. Define list of all symbols:
29 *
30 * #define list_names \
31 * ... \
32 * xxx_name(XXX) \
33 * ...
34 *
35 * 3. Instanciate that list_names:
36 *
37 * list_names
38 *
39 * 4. Redefine xxx_name() as a entry of array for __print_symbolic()
40 *
41 * #undef xxx_name
42 * #define xxx_name(msg) { msg, #msg },
43 *
44 * 5. list_name can now nearlu be used with __print_symbolic() but,
45 * __print_symbolic() dislike last comma of list. So we define a new list
46 * with a dummy element:
47 *
48 * #define list_for_print_symbolic list_names { -1, NULL }
