-/**
- * Contains relevant information about a mode.
- *
- * Necessary information about a mode is stored in this struct
- * which is used by the tarval module to perform calculations
- * and comparisons of values of a such described mode.
- *
- * ATTRIBUTES:
- * - modecode code: An unambiguous int (enum) for the mode
- * - ident *name: Name of this mode. Two modes are different if the name is different.
- * - mode_sort sort: sort of mode specifying possible usage categories
- * - int size: size of the mode in Bits.
- * - unsigned sign:1: signedness of this mode
- * - ... more to come
- * - modulo_shift specifies for modes of kind irms_int_number
- * whether shift applies modulo to value of bits to shift
- *
- * SEE ALSO:
- * The tech report 1999-44 describing FIRM and predefined modes
- * tarval.h
