Subject: [PATCH 03/11] objtool: Compile with debugging symbols
Date: Wed,  9 Mar 2016 00:06:53 -0600
Message-Id: <c295e9ee9ed360dc8b2e1d180c859f11cfc151ef.1457502970.git.jpoimboe@redhat.com>
In-Reply-To: <cover.1457502970.git.jpoimboe@redhat.com>
References: <20160308154909.GA20956@gmail.com> <cover.1457502970.git.jpoimboe@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Compile objtool with debugging symbols ('-g') to help tools like perf
and gdb understand what it's doing.  Combined with '-O2', it's not
always helpful, but it's better than nothing.
