Subject: [PATCH 1/2] perf, tools: In branch stack mode use address history sorting
Date: Mon, 17 Nov 2014 17:58:54 -0800 [thread overview]
Message-ID: <1416275935-20971-1-git-send-email-andi@firstfloor.org> (raw)
From: Andi Kleen <ak@linux.intel.com>
Enable CCKEY_ADDRESS address history sorting with --branch-history.
This makes get_srcline display the source lines correctly,
otherwise all history entries for a function a hunked into one.
