perf report: Adjust sample type validation for synthesized branch stacks
perf report looks at event sample types to determine if branch stacks have been sampled. Adjust the validation to know about instruction tracing options. This change allows the use of the -b option which otherwise would complain with an error like: Error: Selected -b but no branch data. Did you call perf record without -b? # To display the perf.data header info, # please use --header/--header-only options. # Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/r/1443186956-18718-10-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
