;;; Commentary:
|
||
|
||
;; This is loaded into a bare Emacs to make a dumpable one.
|
||
|
||
;; Emacs injects the variable `dump-mode' to tell us how to dump.
|
||
;; We unintern it before allowing user code to run.
|
||
|
||
;; If you add a file to be loaded here, keep the following points in mind:
|
||
|
||
;; i) If the file is no-byte-compile, explicitly load the .el version.
|
||
|
||
;; ii) If the file is dumped with Emacs (on any platform), put the
|
||
;; load statement at the start of a line (leading whitespace is ok).
|
||
|
||
;; iii) If the file is _not_ dumped with Emacs, make sure the load
|
||
;; statement is _not_ at the start of a line. See pcase for an example.
|
||
|
||
;; These rules are so that src/Makefile can construct lisp.mk
|
||
;; automatically. This ensures that the Lisp files are compiled (if
|
||
;; necessary) before the emacs executable is dumped.
|
||
|
||
;;; Code:
|
||
|
||
;; This is used in xdisp.c to determine when bidi reordering is safe.
|
||
;; (It starts non-nil in temacs, but we set it non-nil here anyway, in
|
||
;; case someone loads loadup one more time.) We reset it after
|
||
;; successfully loading charprop.el, which defines the Unicode tables
|
