Subject: [PATCH 2/2] objtool: Fix seg fault with clang-compiled objects
Date: Sat, 30 Dec 2017 14:43:32 -0600
Message-ID: <c0f2231683e9bed40fac1f13ce2c33b8389854bc.1514666459.git.jpoimboe@redhat.com> (raw)
In-Reply-To: <cover.1514666459.git.jpoimboe@redhat.com>
From: Simon Ser <contact@emersion.fr>
Fix a seg fault which happens when an input file provided to 'objtool
orc generate' doesn't have a '.shstrtab' section (for instance, object
files produced by clang don't have this section).
