Subject: [PATCH v2 05/10] tools, perf, script: Set user_set/wildcard_set for +- fields in -F
From: Andi Kleen <ak@...ux.intel.com>
The branch target output relies on the user_set flag to determine
if the branch target should be implicitely printed. When
modifying the fields with + or - also set user_set,
so that ADDR can be removed. We also need to set wildcard_set
to make the initial sanity check pass.
Before:
% perf script --itrace=cr -F +callindent,-ip,-sym,-symoff,-addr
