perf script: Explicitly handle known default print arg type
Handle the print argument types brought by the new libparsevent in perl scripting engine. PRINT_BSTRING and PRINT_DYNAMIC_ARRAY are treated just like strings and thus don't require specific processing. But PRINT_FUNC need specific plugins which are not yet handled, lets warn if we meet this case. This fixes: util/scripting-engines/trace-event-perl.c: In function define_event_symbol: util/scripting-engines/trace-event-perl.c:188: error: enumeration value PRINT_BSTRING not handled in switch util/scripting-engines/trace-event-perl.c:188: error: enumeration value PRINT_DYNAMIC_ARRAY not handled in switch util/scripting-engines/trace-event-perl.c:188: error: enumeration value PRINT_FUNC not handled in switch Reported-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Frederic Weisbecker <fweisbec@redhat.com> Cc: Frederic Weisbecker <fweisbec@redhat.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Namhyung Kim <namhyung.kim@lge.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Tom Zanussi <tzanussi@gmail.com> Link: http://lkml.kernel.org/r/1337697049-30251-1-git-send-email-fweisbec@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
