perf script: Print callchains and symbols if they exist
The intent of perf-script is to dump the events and information in the file. H/W, S/W and raw events all dump callchains if they are present; might as well make that the default for tracepoints too. v2: Only add options for sym, dso and ip if callchains are present Signed-off-by: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Link: http://lkml.kernel.org/r/1384920457-5986-1-git-send-email-dsahern@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
