From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Santos Subject: [PATCH v6 5/25] compiler{,-gcc4}.h: Remove duplicate macros Date: Thu, 27 Sep 2012 20:54:21 -0500 Message-ID: <1348797281-25021-6-git-send-email-daniel.santos@pobox.com> References: <1348797281-25021-1-git-send-email-daniel.santos@pobox.com> Return-path: In-Reply-To: <1348797281-25021-1-git-send-email-daniel.santos@pobox.com> Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org, linux-doc@vger.kernel.org, linux-sparse@vger.kernel.org, Akinobu Mita , Andi Kleen , Andrea Arcangeli , Andrew Morton , Christopher Li , David Daney , David Howells , David Rientjes , David Woodhouse , Don Zickus , Greg Kroah-Hartman , Hidetoshi Seto , "H. Peter Anvin" Cc: Daniel Santos List-Id: linux-sparse@vger.kernel.org __linktime_error() does the same thing as __compiletime_error() and is only used in bug.h. Since the macro defines a function attribute that will cause a failure at compile-time (not link-time), it makes more sense to keep __compiletime_error(), which is also neatly mated with __compiletime_warning().
