27 * Implementation of the datastructure to hold
30 * This module supplies a datastructure to represent all types
31 * known in the compiled program. This includes types specified
32 * in the program as well as types defined by the language. In the
33 * view of the intermediate representation there is no difference
34 * between these types.
36 * There exist several kinds of types, arranged by the structure of
37 * the type. A type is described by a set of attributes. Some of
38 * these attributes are common to all types, others depend on the
41 * Types are different from the modes defined in irmode: Types are
42 * on the level of the programming language, modes at the level of
43 * the target processor.
