* - owner: A compound type this entity is a part of.
* - type: The type of this entity.
- * - name: The string that represents this entity in the source program. * - allocation: A flag saying whether the entity is dynamically or statically * allocated (values: dynamic_allocated, static_allocated,
- * automatic_allocated).
- * - visibility: A flag indicating the visibility of this entity (values: local,
- * external_visible, external_allocated)
- * - variability: A flag indicating the variability of this entity (values:
- * uninitialized, initialized, part_constant, constant)
- * - volatility: @@@
+ * - name: The string that represents this entity in the source program
+ * - linkage: A flag indicating how the linker treats a symbol
* - offset: The offset of the entity within the compound object in bytes. Only set
* if the owner in the state "layout_fixed".
* - offset_bits_remainder: The offset bit remainder of a bitfield entity (in a compound)
* - link: A void* to associate some additional information with the entity.
* - irg: If the entity is a method this is the ir graph that represents the
* code of the method.
- * - peculiarity: The peculiarity of the entity. If the entity is a method this
- * indicates whether the entity represents
- * a real method or whether it only exists to describe an interface.
- * In that case there nowhere exists code for this entity and this entity
- * is never dynamically used in the code.
- * Values: description, existent. Default: existent.
* - visited: visited flag. Master flag is type_visited.
*
* These fields can only be accessed via access functions.

- * The visibility of a type indicates, whether entities of this type

- *
- * An entity of a type is allocated in external code, if the external
- * code declares a variable of this type, or dynamically allocates
- * an entity of this type. If the external code declares a (compound)
- * type, that contains entities of this type, the visibility also
- * must be external_allocated.
- *
- * The visibility must be higher than that of all entities, if the
- * type is a compound. Here it is questionable, what happens with
- * static entities. If these are accessed external by direct reference,
- * (a static call to a method, that is also in the dispatch table)
- * it should not affect the visibility of the type.
- *
- *
- * @@@ Do we need a visibility for types?
- * I change the layout of types radically when doing type splitting.
- * I need to know, which fields of classes are accessed in the RTS,
- * e.g., [_length. I may not move [_length to the split part.
- * The layout though, is a property of the type.
- *
- * One could also think of changing the mode of a type ...
- *
- * But, we could also output macros to access the fields, e.g.,
- * ACCESS_[_length (X) X->length // conventional
- * ACCESS_[_length (X) X->_split_ref->length // with type splitting
- *
- * For now I implement this function, that returns the visibility
- * based on the visibility of the entities of a compound ...
- *
- * This function returns visibility_external_visible if one or more
- * entities of a compound type have visibility_external_visible.
- * Entities of types are never visibility_external_allocated (right?).
- * Else returns visibility_local.
