Literal-unsigned

Make-literal-unsigned

Basic constructor macro for literal-unsigned structures.

Syntax

(make-literal-unsigned [:value <value>] 
                       [:size <size>])

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

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

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-literal-unsigned

(defmacro make-literal-unsigned (&rest args)
  (std::make-aggregate 'literal-unsigned
                       args '((:value) (:size))
                       'make-literal-unsigned
                       nil))

Function: literal-unsigned

(defun literal-unsigned (value size)
  (declare (xargs :guard (and (integerp value)
                              (leo-early::bitsizep size))))
  (declare (xargs :guard t))
  (let ((__function__ 'literal-unsigned))
    (declare (ignorable __function__))
    (b* ((value (mbe :logic (ifix value) :exec value))
         (size (mbe :logic (leo-early::bitsize-fix size)
                    :exec size)))
      (cons :unsigned (list value size)))))
