From 37fed3de555199733805a2d3e03aee7727c09ea4 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 18 Sep 2018 05:32:09 -0700 Subject: perf script: Allow sym and dso without ip, addr Currently sym and dso require printing ip and addr because the print function is tied to those outputs. With callindent it makes sense to print the symbol or dso without numerical IP or ADDR. So change the dependency check to only check the underlying attribute. Also 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. This allows to remove a lot of noise in callindent output by dropping the numerical addresses, which are not all that useful.
