From fef51ecd1056b5e090c9fb73e0833bd751389572 Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Mon, 31 Oct 2016 09:19:53 +0800 Subject: [PATCH] perf report: Show branch info in callchain entry for browser 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.
