From 4dc549e58b6ebf63554cd466d5ceb0e9c70ab859 Mon Sep 17 00:00:00 2001 From: Jiri Olsa <jolsa@redhat.com> Date: Sun, 20 Apr 2014 10:50:00 +0200 Subject: [PATCH] perf tools: Disable libdw unwind for all but x86 arch So far there's only x86 libdw unwind support merged in perf. Disable it on all other architectures in case libdw unwind support is detected in system.
