Subject: [PATCH V7 7/7] perf tools: another fix for annotate_browser__callq()
Date: Mon, 14 Oct 2013 13:43:44 +0300	[thread overview]
Message-ID: <1381747424-3557-8-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1381747424-3557-1-git-send-email-adrian.hunter@intel.com>

The target address is provided by objdump and is not
necessary a memory address.  Add a helper to get the
correct address.
