Subject: [PATCH 2/5] perf: unwind: pass symbol source to libunwind
Date: Sun, 27 Sep 2015 20:37:56 +0200	[thread overview]
Message-ID: <1443379079-29133-2-git-send-email-rabin.vincent@axis.com> (raw)
In-Reply-To: <1443379079-29133-1-git-send-email-rabin.vincent@axis.com>

Even if --symfs is used to point to the debug binaries, we send in the
non-debug filenames to libunwind, which leads to libunwind not finding
the debug frame.  Fix this.
