Instr-branch

Change-instr-branch

Modifying constructor for instr-branch structures.

Syntax

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

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

We construct a new instr-branch 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.

                           (:rs1 . instr-branch->rs1)
                           (:rs2 . instr-branch->rs2)
