perf_counter tools: Resolve symbols in callchains
This patch resolves the names, when possible, of each ip present in the callchains while using the -c option with perf report. Example: 5.40% [k] __d_lookup 5.37% perf_callchain perf_counter_overflow intel_pmu_handle_irq perf_counter_nmi_handler notifier_call_chain atomic_notifier_call_chain notify_die do_nmi nmi do_lookup __link_path_walk path_walk do_path_lookup user_path_at sys_faccessat sys_access system_call_fastpath 0x7fb609846f77 0.01% perf_callchain perf_counter_overflow intel_pmu_handle_irq perf_counter_nmi_handler notifier_call_chain atomic_notifier_call_chain notify_die do_nmi nmi do_lookup __link_path_walk path_walk do_path_lookup user_path_at sys_faccessat Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Anton Blanchard <anton@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> LKML-Reference: <1246419315-9968-3-git-send-email-fweisbec@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
