+ *
+ * NAME
+ * tv -- TargetValue, short tarval.
+ * Internal representation for machine values.
+ *
+ * AUTHORS
+ * Matthias Heil
+ *
+ * DESCRIPTION
+ * Tarvals represent target machine values. They are typed by modes.
+ * Tarvals only represent values of mode_sort:
+ * int_number,
+ * float_number,
+ * boolean,
+ * reference,
+ * character
+ *
+ * In case of references the module accepts an entity to represent the
+ * value.
+ * Furthermore, computations and conversions of these values can
+ * 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 ...
+ *
+ * SEE ALSO
+ * Techreport 1999-14
+ * irmode.h for the modes definitions
+ * irnode.h for the pnc_numbers table
+ *
+ * tarval_init1 and tarval_init2 for initialization of the
+ * module

+ * This function creates a new tarval representing the value represented

+ *
+ * This function accepts the following strings:
+ *
+ * if mode is int_number:
+ * - 0(x|X)[0-9a-fA-F]+ (hexadecimal representation)
+ * - 0[0-7]* (octal representation)

+ *
+ * if mode if float_number:
+ * - (+|-)?(decimal int) (. (decimal int))? ((e|E)(+|-)?(decimal int))?
+ *
+ * if mode is boolean: true, True, TRUE ... False... 0, 1,
+ *
+ * if mode is reference: hexadecimal of decimal number as int
+ *
+ * if mode is character: hex or dec
+ *
+ * Leading and/or trailing spaces are ignored
+ *
+ * @return
+ * A tarval of proper type representing the requested value is returned.
+ * Tarvals are unique, so for any value/mode pair at most one tarval will
