Instr-jal

Make-instr-jal

Basic constructor macro for instr-jal structures.

Syntax

(make-instr-jal [:rd <rd>] 
                [:imm <imm>])

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

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

Definition

                       nil))

         (imm (mbe :logic (ubyte20-fix imm)
                   :exec imm)))
      (cons :jal (list rd imm)))))
