From 763122ade725592402190f5ff3b8d2edf42b87e8 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Sat, 13 Sep 2014 07:15:05 +0300 Subject: perf tools: Disable kernel symbol demangling by default Some Linux symbols (for example __vt_event_wait) are interpreted by the demangler as C++ mangled names, which of course they aren't. Disable kernel symbol demangling by default to avoid this, and allow enabling it with a new option --demangle-kernel for those who wish it.
