[PATCH 21/39] perf report: Also do default setup for synthesized branch stacks

From: Arnaldo Carvalho de Melo
Date: Mon Sep 28 2015 - 17:22:10 EST


From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

The 'perf report' tool will default to displaying branch stacks (-b
option) if they are present. Make that also happen for synthesized
branch stacks.
