Isuffix-lu

Make-isuffix-lu

Basic constructor macro for isuffix-lu structures.

Syntax

(make-isuffix-lu [:length <length>] 
                 [:unsigned <unsigned>])

This is the usual way to construct isuffix-lu structures. It simply conses together a structure with the specified fields.

This macro generates a new isuffix-lu structure from scratch. See also change-isuffix-lu, which can "change" an existing structure, instead.

         (unsigned (mbe :logic (usuffix-fix unsigned)
                        :exec unsigned)))
      (cons :lu (list length unsigned)))))
