;;; New Features:
|

;;;
|
||||
;;; o The form `defsubst' is just like `defun', except that the function
|
||||
;;; generated will be open-coded in compiled code which uses it. This
|
||||
;;; means that no function call will be generated, it will simply be
|
||||
;;; spliced in. Elisp functions calls are very slow, so this can be a
|
||||
;;; spliced in. Lisp functions calls are very slow, so this can be a
|
||||
;;; big win.
|
||||
;;;
|
||||
;;; You can generally accomplish the same thing with `defmacro', but in
|
||||
;;; that case, the defined procedure can't be used as an argument to
|
||||
;;; mapcar, etc.
|
||||
;;;
|
||||
;;; o You can make a given function be inline even if it has already been
|
||||
;;; defined with `defun' by using the `proclaim-inline' form like so:
|
||||
;;; (proclaim-inline my-function)
|
||||
;;; This is, in fact, exactly what `defsubst' does. To make a function no
|
||||
;;; longer be inline, you must use `proclaim-notinline'. Beware that if
|
||||
;;; you define a function with `defsubst' and later redefine it with
|
||||
;;; `defun', it will still be open-coded until you use proclaim-notinline.
|
||||
;;;
|
||||
;;; o You can also open-code one particular call to a function without
|
||||
;;; open-coding all calls. Use the 'inline' form to do this, like so:
