Subject: [PATCH 2/4] perf tools: Disable libdw unwind for all but x86 arch
Date: Wed, 23 Apr 2014 13:31:20 +0200 [thread overview]
Message-ID: <1398252682-17185-3-git-send-email-jolsa@redhat.com> (raw)
In-Reply-To: <1398252682-17185-1-git-send-email-jolsa@redhat.com>
So far there's only x86 libdw unwind support merged in perf.
Disable it on all other architectures in case libdw unwind
support is detected in system.
