Instr-store

Change-instr-store

Modifying constructor for instr-store structures.

Syntax

(change-instr-store x 
                    [:funct <funct>] 
                    [:rs1 <rs1>] 
                    [:rs2 <rs2>] 
                    [:imm <imm>])

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

We construct a new instr-store 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.
