+/* The hell below need some explanations. For each symbolic number, we need to
+ * define it with TRACE_DEFINE_ENUM() and in a list for __print_symbolic.
+ *
+ * 1. Define a new macro that call TRACE_DEFINE_ENUM():
+ *
+ * #define xxx_name(sym) TRACE_DEFINE_ENUM(sym);
+ *
+ * 2. Define list of all symbols:
+ *
+ * #define list_names \
+ * ... \
+ * xxx_name(XXX) \
+ * ...
+ *
+ * 3. Instantiate that list_names:
+ *
+ * list_names
+ *
+ * 4. Redefine xxx_name() as an entry of array for __print_symbolic()
+ *
+ * #undef xxx_name
+ * #define xxx_name(msg) { msg, #msg },
+ *
+ * 5. list_name can now nearly be used with __print_symbolic() but,
+ * __print_symbolic() dislike last comma of list. So we define a new list
+ * with a dummy element:
+ *
+ * #define list_for_print_symbolic list_names { -1, NULL }
