Subject: [PATCH 5/6] perf report: Show branch info in callchain entry with browser mode
Date: Wed, 19 Oct 2016 17:25:52 +0800	[thread overview]
Message-ID: <1476869153-15424-6-git-send-email-yao.jin@linux.intel.com> (raw)
In-Reply-To: <1476869153-15424-1-git-send-email-yao.jin@linux.intel.com>

If the branch is 100% predicated then the "predicated" is hide.
Similarly, if there is no branch tsx abort, the "abort" is hide.
There is only cycles shown (cycle is supported on skylake platform,
older platform would be 0).
