Subject: [PATCH v4 5/8] perf, tools, script: Print DSO for callindent
Date: Mon,  3 Sep 2018 09:22:46 -0700	[thread overview]
Message-ID: <20180903162249.36304-6-andi@firstfloor.org> (raw)
In-Reply-To: <20180903162249.36304-1-andi@firstfloor.org>

From: Andi Kleen <ak@linux.intel.com>

Now that we don't need to print the IP/ADDR for callindent the DSO
is also not printed. It's useful for some cases, so add an own DSO
printout for callindent for the case when IP/ADDR is not enabled.

Before:

% perf script --itrace=cr -F +callindent,-ip,-sym,-symoff,-addr

(in the kernel case of course it's not very useful, but it's important
with user programs where symbols are not unique)
