From fb7d0b3cefb80a105f7fd26bbc62e0cbf9192822 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Mon, 24 Jan 2011 11:13:04 -0500 Subject: perf tool: Fix gcc 4.6.0 issues GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf due to the -Werror=unused-but-set-variable flag. I've gone through and annotated some of the assignments that had side effects (ie: return value from a function) with the __used annotation, and in some cases, just removed unused code. In a few cases, we were assigning something useful, but not using it in later parts of the function. kyle@dreadnought:~/src% gcc --version gcc (GCC) 4.6.0 20110122 (Red Hat 4.6.0-0.3) Cc: Ingo Molnar LKML-Reference: <20110124161304.GK27353@bombadil.infradead.org> Signed-off-by: Kyle McMartin [ committer note: Fixed up the annotation fixes, as that code moved recently ] Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/scripting-engines/trace-event-python.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'tools/perf/util/scripting-engines/trace-event-python.c') diff --git a/tools/perf/util/scripting-engines/trace-event-python.c b/tools/perf/util/scripting-engines/trace-event-python.c index c6d99334bdf..2040b853852 100644 --- a/tools/perf/util/scripting-engines/trace-event-python.c +++ b/tools/perf/util/scripting-engines/trace-event-python.c @@ -248,8 +248,7 @@ static void python_process_event(int cpu, void *data, context = PyCObject_FromVoidPtr(scripting_context, NULL); PyTuple_SetItem(t, n++, PyString_FromString(handler_name)); - PyTuple_SetItem(t, n++, - PyCObject_FromVoidPtr(scripting_context, NULL)); + PyTuple_SetItem(t, n++, context); if (handler) { PyTuple_SetItem(t, n++, PyInt_FromLong(cpu)); -- cgit v1.2.3-18-g5258 From be6d842a65babc54e2b204b382df2529e304be48 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Wed, 9 Mar 2011 22:23:23 -0700 Subject: perf script: Change process_event prototype Prepare for handling of samples for any event type.

Good also because it does an extra validation, checking that the ID is valid when present. When that is not the case, the overhead is just a branch + function call (perf_evlist__id2evsel).
