    Change-stat

    Modifying constructor for stat structures.

    Syntax
    (change-stat x 
                 [:xregs <xregs>] 
                 [:pc <pc>] 
                 [:memory <memory>] 
                 [:error <error>]) 
    

    This is an often useful alternative to make-stat.

    We construct a new stat 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.

    Macro: change-stat

    (defmacro change-stat (x &rest args)
      (std::change-aggregate 'stat
                             x args
                             '((:xregs . stat->xregs)
                               (:pc . stat->pc)
                               (:memory . stat->memory)
                               (:error . stat->error))
                             'change-stat
                             'nil))
