From 138d2f22f731bc3faf6de26b67e2b50ce9131541 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Mattias=20Engdeg=C3=A5rd?= Date: Mon, 6 Jun 2022 10:47:42 +0200 Subject: [PATCH] Test warning suppressions with lexical binding * test/lisp/emacs-lisp/bytecomp-tests.el (test-byte-comp-compile-and-load): Add lexical cookie to file being compiled as part of the test. (bytecomp-test--with-suppressed-warnings): Comment out the test for suppressing warnings when attempting to let-bind `nil`, as that (1) doesn't work and (2) is a silly thing to do anyway. --- test/lisp/emacs-lisp/bytecomp-tests.el | 20 ++++++++++++++------ 1 file changed, 14 insertions(+), 6 deletions(-) diff --git a/test/lisp/emacs-lisp/bytecomp-tests.el b/test/lisp/emacs-lisp/bytecomp-tests.el index 049eed10f94..39f053136ae 100644 --- a/test/lisp/emacs-lisp/bytecomp-tests.el +++ b/test/lisp/emacs-lisp/bytecomp-tests.el @@ -747,6 +747,7 @@ byte-compiled.
