Subject: [PATCH] perf tools: Disable libdw unwind for all but x86 arch
Date: Sun, 20 Apr 2014 12:00:06 +0200 [thread overview]
Message-ID: <1397988006-14158-1-git-send-email-jolsa@redhat.com> (raw)
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.
