From cc5f02f2be8d3354986bad5703ee8a983872f140 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 24 Apr 2018 11:32:30 -0300 Subject: [PATCH] perf script: Use thread__find_symbol() instead of ad-hoc equivalent In dc323ce8e72d ("perf script: Enable printing of branch stack") it first tries to find the map for an address, then the symbol in the DSO backing that map, for that address, well, this is what thread__find_symbol() does, so just use it and make the code shorter.
