14 * This module supplies routines that support changing the type graph.
19 * - replaces one type by the other.
20 * @param The old type that shall be replaced by the new type.
21 * Old type is replaced by new_type. All references to old_type
22 * now point to new_type. The memory for the old type is destroyed,
23 * but still used. Therefore it is not freed.
24 * All referenced to this memory will be lost after a certain while.
25 * An exception is the list of types in irp (irprog.h).
26 * In the future there might be a routine to recover the memory, but
27 * this will be at considerable runtime cost.
30 INLINE void exchange_types(type *old_type, type *new_type);
34 * - skip id types until a useful type is reached.
35 * @param A type of arbitrary kind.
36 * tp if it is not an id type.
37 * If tp is an id type retruns the real type it stands for.
40 INLINE type *skip_tid(type *tp);
