Subject: [PATCH] ubsan: don't mark __ubsan_handle_builtin_unreachable as noreturn
Date: Fri,  2 Feb 2018 16:47:39 +0100
Message-ID: <20180202154813.1625742-1-arnd@arndb.de> (raw)

gcc-8 complains about the prototype for this function:

lib/ubsan.c:432:1: error: ignoring attribute 'noreturn' in declaration of a built-in function '__ubsan_handle_builtin_unreachable' because it conflicts with attribute 'const' [-Werror=attributes]

This removes the noreturn attribute.
