[PATCH 02/10] perf, tools, report: Add flag for non ANY branch mode

From: Andi Kleen
Date: Sun May 10 2015 - 09:52:32 EST


From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Later patches need to cheaply check that the branch mode is in ANY.
Add a new function to check all event attrs and add a flag to the
report state, which is then initialized.
