/**
* An abstract data type to represent types.
* the type. These are distinguished by a type opcode.
* A type is described by a set of attributes. Some of these attributes
* are common to all types, others depend on the kind of the type.
- *
- * The following describes the common attributes. They can only be
- * accessed by the functions given below.
- *
- * The common fields are:
- *
- * - firm_kind: A firm_kind tag containing k_type. This is useful
- * for dynamically checking whether a node is a type node.
- * - type_op: A tp_op specifying the kind of the type.
- * - name: An identifier specifying the name of the type. To be
- * set by the frontend.
- * - visibility: The visibility of this type.
- * - size: The size of the type, i.e. an entity of this type will
- * occupy size bits in memory. In several cases this is
- * determined when fixing the layout of this type (class,
- * struct, union, array, enumeration).
- * - alignment The alignment of the type, i.e. an entity of this type will
- * be allocated an an address in memory with this alignment.
- * In several cases this is determined when fixing the layout
- * of this type (class, struct, union, array)
- * - mode: The mode to be used to represent the type on a machine.
- * - state: The state of the type. The state represents whether the
- * layout of the type is undefined or fixed (values: layout_undefined
- * or layout_fixed). Compound types can have an undefined
- * layout. The layout of the basic types primitive and pointer
- * is always layout_fixed. If the layout of
- * compound types is fixed all entities must have an offset
- * and the size of the type must be set.
- * A fixed layout for enumeration types means that each enumeration
- * is associated with an implementation value.
- * - assoc_type: The associated lowered/upper type.
- * - visit: A counter for walks of the type information.
- * - link: A void* to associate some additional information with the type.
- *
- * These fields can only be accessed via access functions.
- *
- * Depending on the value of @c type_op, i.e., depending on the kind of the
- * type the adt contains further attributes. These are documented below.
- *
- * @see
- *
- * @link class_type class @endlink, @link struct_type struct @endlink,
- * @link method_type method @endlink, @link union_type union @endlink,
- * @link array_type array @endlink, @link enumeration_type enumeration @endlink,
- * @link pointer_type pointer @endlink, @link primitive_type primitive @endlink
- *
- * @todo
- * mode maybe not global field??
