* @summary
* Tarvals represent target machine values. They are typed by modes.
* Tarvals only represent values of mode_sort:

* boolean,
* reference,
* character
* - int_number,
* - float_number,
* - boolean,

* In case of references the module accepts an entity to represent the

* be performed.
*
* USES
* This module is closely related to the irmode module, as the modes
* defined there are thoroughly used throughout the whole module.
* Also, the comparison functions rely on the definition of comparison
* values in the irnode module.

* HISTORY
* The original tv module originated in the fiasco compiler written ...
* This is the new version, described in the tech report 1999-14 by ...
