From 14135663f1d770bb057f8bf345e5436c985eb29c Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 31 Oct 2013 10:17:39 +0900 Subject: perf tools: Apply percent-limit to cumulative percentage If -g cumulative option is given, it needs to show entries which don't have self overhead. So apply percent-limit to accumulated overhead percentage in this case.
