27 ;; This is loaded into a bare Emacs to make a dumpable one.
29 ;; If you add a file to be loaded here, keep the following points in mind:
31 ;; i) If the file is no-byte-compile, explicitly load the .el version.
32 ;; Such files should (where possible) obey the doc-string conventions
33 ;; expected by make-docfile. They should also be added to the
34 ;; uncompiled[] list in make-docfile.c.
36 ;; ii) If the file is dumped with Emacs (on any platform), put the
37 ;; load statement at the start of a line (leading whitespace is ok).
39 ;; iii) If the file is _not_ dumped with Emacs, make sure the load
40 ;; statement is _not_ at the start of a line. See pcase for an example.
42 ;; These rules are so that src/Makefile can construct lisp.mk automatically.
43 ;; This ensures both that the Lisp files are compiled (if necessary)
44 ;; before the emacs executable is dumped, and that they are passed to
45 ;; make-docfile. (Any that are not processed for DOC will not have
46 ;; doc strings in the dumped Emacs.)
50 ;; This is used in xdisp.c to determine when bidi reordering is safe.
51 ;; (It starts non-nil in temacs, but we set it non-nil here anyway, in
52 ;; case someone loads loadup one more time.) We reset it after
53 ;; successfully loading charprop.el, which defines the Unicode tables
54 ;; bidi.c needs for its job.
