From 6f736735e30f51805f6be31d20a4bf5b0ae91bae Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 14 Apr 2016 17:45:51 -0300 Subject: perf evsel: Require that callchains be resolved before calling fprintf_{sym,callchain} This way the print routine merely does printing, not requiring access to the resolving machinery, which helps disentangling the object files and easing creating subsets with a limited functionality set.
