Instr-jal

Change-instr-jal

Modifying constructor for instr-jal structures.

Syntax

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

This is an often useful alternative to make-instr-jal.

We construct a new instr-jal structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

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