Subject: [PATCH 2/9] perf, tools, report: Add flag for non ANY branch mode
From: Andi Kleen <ak@...ux.intel.com>
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.
v2: Rename flag
Acked-by: Jiri Olsa <jolsa@...nel.org>
