+ * ir_node - a datatype representing a Firm node

+ * The common fields are:

+ * - firm_kind - A firm_kind tag containing k_type. This is useful
+ * for dynamically checking whether a node is a ir_node.
+ * - arity - The number of predecessors in the Firm graph.
+ * - in - A list with the predecessors in the Firm graph. There are
+ * routines to access individual elements and to obtain the
+ * array. The method returning the array should not be used.
+ * - mode - The mode of the node. There are routines to get the mode
+ * but also to access the mode's fields directly.
+ * - opcode - The opcode of the node. There are routines to get the opcode
+ * but also to access the opcode's fields directly.
+ * - node_nr - A unique number for the node. Available only if debugging

+ exists. Else it passes control along output n (even if this Proj does not
