From 993ac88d5892629fbe1f8a54857f9947f49f0d96 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Thu, 8 Mar 2012 23:47:47 +0100 Subject: perf report: Auto-detect branch stack sampling mode This patch enhances perf report to auto-detect when the perf.data file contains samples with branch stacks. That way it is not necessary to use the -b option. To force branch view mode to off, simply use --no-branch-stack.
