Jin Yao 8577ae6b04 perf report: Show branch info in callchain entry for stdio mode ... If the branch is 100% predicted then the "predicted" is hidden. Similarly, if there is no branch tsx abort, the "abort" is hidden. There is only cycles shown (cycle is supported on skylake platform, older platform would be 0). If no iterations, the "iterations" is hidden. For example: |--29.93%--main div.c:39 (predicted:50.6%, cycles:1, iterations:18) | main div.c:44 (predicted:50.6%, cycles:1) | | | --22.69%--main div.c:42 (cycles:2, iterations:17) | compute_flag div.c:28 (cycles:2) | | | --10.52%--compute_flag div.c:27 (cycles:1) | rand rand.c:28 (cycles:1) | rand rand.c:28 (cycles:1) | __random random.c:298 (cycles:1) | __random random.c:297 (cycles:1) | __random random.c:295 (cycles:1) | __random random.c:295 (cycles:1) | __random random.c:295 (cycles:1) | __random random.c:295 (cycles:6) Signed-off-by: Yao Jin <yao.jin@linux.intel.com> Acked-by: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@intel.com> Cc: Linux-kernel@vger.kernel.org Cc: Yao Jin <yao.jin@linux.intel.com> Link: http://lkml.kernel.org/r/1477876794-30749-5-git-send-email-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2016-11-14 13:33:47 -03:00
