134 * The arguments is a list surrounded by parentheses. The items
136 * - The module handle as returned by firm_dbg_register().
137 * - The debug mask that you want associate with this message.
138 * - A format string for the message to pass to ir_printf().
139 * - Further optional arguments are passed to ir_printf().
141 * The mask is anded against the module's mask. If both have some bits
142 * in common, the message is issued. If the given mask is 0, the message
143 * is always dumped regardless of the module's mask. You can also use
144 * the mask in a level based manner, see firm_dbg_level_t.
146 * Here is an example:
148 * DBG((my_mod, MASK_ERR, "ir node %n is not green", node))
150 * DBG((my_mod, LEVEL_DEFAULT, "entity %e has type %t", ent, type))
