From: Paul Eggert Date: Tue, 14 Aug 2012 17:45:25 +0000 (-0700) Subject: Use bool for Emacs Lisp booleans. X-Git-Tag: emacs-24.2.90~676 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=f5d9e83a70335308d5c6d18d62a7ac94f4bd431c;p=emacs.git Use bool for Emacs Lisp booleans. This is more natural, and on my platform (GCC 4.7.1 x86-64) it makes Emacs's text size .03% smaller and presumably a bit faster. * admin/merge-gnulib (GNULIB_MODULES): Add stdbool. This documents a new direct dependency; stdbool was already being used indirectly via other gnulib modules. * lib-src/make-docfile.c (enum global_type): Sort values roughly in decreasing alignment, except put functions last. (compare_globals): Use this new property of enum global_type. (write_globals): Use bool, not int, for booleans. * src/lisp.h: Include . (struct Lisp_Boolfwd, defvar_bool): * src/lread.c (defvar_bool): Use bool, not int, for Lisp booleans. * src/regex.c [!emacs]: Include . (false, true): Remove; does this for us now. --- diff --git a/admin/ChangeLog b/admin/ChangeLog index 18bb44491a1..c579930d2bf 100644 --- a/admin/ChangeLog +++ b/admin/ChangeLog @@ -1,3 +1,10 @@ +2012-08-14 Paul Eggert + + Use bool for Emacs Lisp booleans. + * merge-gnulib (GNULIB_MODULES): Add stdbool.
