From 45d8e8025a2b2a6996be92d769fb6763bfb3cbae Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Thu, 3 Jun 2010 15:50:01 +0200 Subject: [PATCH] perf annotate: Ask objdump to demangle symbols MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Perf report is demangling symbols but not annotate. The former uses internal demangling via libbdf or libiberty. The latter executes objdump which by default does not demangle symbols. This patch adds the -C option to the objdump cmdline to enable symbol demangling. Cc: David S.
