From e326e7524531c5c6de4a8cf8eeed60b4a9f47637 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Tue, 22 May 2012 16:30:48 +0200 Subject: [PATCH] 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 Signed-off-by: Frederic Weisbecker Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Steven Rostedt Cc: Tom Zanussi Link: http://lkml.kernel.org/r/1337697049-30251-1-git-send-email-fweisbec@gmail.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/scripting-engines/trace-event-perl.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/tools/perf/util/scripting-engines/trace-event-perl.c b/tools/perf/util/scripting-engines/trace-event-perl.c index e30749e38a9b..d50658b7d9e0 100644 --- a/tools/perf/util/scripting-engines/trace-event-perl.c +++ b/tools/perf/util/scripting-engines/trace-event-perl.c @@ -209,6 +209,8 @@ static void define_event_symbols(struct event *event, define_symbolic_values(args->symbol.symbols, ev_name, cur_field_name); break; + case PRINT_BSTRING: + case PRINT_DYNAMIC_ARRAY: case PRINT_STRING: break; case PRINT_TYPE: @@ -220,7 +222,9 @@ static void define_event_symbols(struct event *event, define_event_symbols(event, ev_name, args->op.left); define_event_symbols(event, ev_name, args->op.right); break; + case PRINT_FUNC: default: + pr_err("Unsupported print arg type\n"); /* we should warn... */ return; } -- 2.30.2
