31 * Declarations of an ir node.
35 * @defgroup ir_node Declarations of an ir node.
37 * The type definition of ir_node is also in irgraph.h to resolve
38 * recursion between irnode.h and irgraph.h
40 * ir_node - a datatype representing a Firm node
42 * The common fields are:
44 * - firm_kind - A firm_kind tag containing k_type. This is useful
45 * for dynamically checking whether a node is a ir_node.
46 * - arity - The number of predecessors in the Firm graph.
47 * - in - A list with the predecessors in the Firm graph. There are
48 * routines to access individual elements and to obtain the
49 * array. The method returning the array should not be used.
50 * - mode - The mode of the node. There are routines to get the mode
51 * but also to access the mode's fields directly.
52 * - opcode - The opcode of the node. There are routines to get the opcode
53 * but also to access the opcode's fields directly.
54 * - node_nr - A unique number for the node. Available only if debugging

357 /* We distinguish three kinds of Cond nodes. These can be distinguished
358 by the mode of the selector operand and an internal flag of type cond_kind.
359 First we distinguish binary Conds and switch Conds.
360 A binary Cond has as selector a boolean value. Proj(0) projects the control
361 flow for case "False", Proj(1) the control flow for "True". A binary Cond
362 is recognized by the boolean selector.
363 The switch Cond has as selector an unsigned integer. It produces as result
364 an n+1 Tuple (cf0, ... , cfn) of control flows.
365 We differ two flavors of this Cond. The first, the dense Cond, passes
366 control along output i if the selector value is i, 0 <= i <= n. If the
367 selector value is >n it passes control along output n.
368 The second Cond flavor differences in the treatment of cases not specified in
369 the source program. It magically knows about the existence of Proj nodes.
370 It only passes control along output i, 0 <= i <= n, if a node Proj(Cond, i)
371 exists. Else it passes control along output n (even if this Proj does not
372 exist.) This Cond we call "fragmentary". There is a special constructor
373 new_defaultProj that automatically sets the flavor.
374 The two switch flavors are distinguished by a flag of type cond_kind.
375 Default flavor is "dense"
