4 * file type.c - implementation of the datastructure to hold
7 * (C) 2001 by Universitaet Karlsruhe
9 * Martin Trapp, Christian Schaefer, Goetz Lindenmaier
12 * This module supplies a datastructure to represent all types
13 * known in the compiled program. This includes types specified
14 * in the program as well as types defined by the language. In the
15 * view of the intermediate representation there is no difference
16 * between these types.
18 * There exist several kinds of types, arranged by the structure of
19 * the type. A type is described by a set of attributes. Some of
20 * these attributes are common to all types, others depend on the
23 * Types are different from the modes defined in irmode: Types are
24 * on the level of the programming language, modes at the level of
25 * the target processor.
