From 8bf98b89688c3d7ec071bf26d49761e38d846b47 Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Sat, 8 Sep 2012 08:35:51 +0300 Subject: [PATCH 1/9] perf bench: fix assert when NDEBUG is defined MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When NDEBUG is defined, the assert macro will be expanded to nothing. Some assert calls used in perf are also including some functionality (e.g. system calls), not only validity checks. Therefore, if NDEBUG is defined, this functionality will be removed along with the assert. Perf also defines BUG_ON based on assert, so it has the same problem. Define BUG_ON so that the condition will be executed when NDEBUG is defined. Replace the assert statements that have these side effects with BUG_ON. For defining BUG_ON, use "if (cond) {}" insted of "if (cond) ;" because in the latter case build fails with "error: suggest braces around empty body in an ‘if’ statement [-Werror=empty-body]" Suggested-by: Peter Zijlstra Signed-off-by: Irina Tirdea Reviewed-by: Namhyung Kim Reviewed-by: Pekka Enberg Cc: David Ahern Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Steven Rostedt Link: http://lkml.kernel.org/r/1347082551-2394-1-git-send-email-irina.tirdea@intel.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/bench/sched-pipe.c | 6 +++--- tools/perf/util/include/linux/kernel.h | 4 ++++ 2 files changed, 7 insertions(+), 3 deletions(-) diff --git a/tools/perf/bench/sched-pipe.c b/tools/perf/bench/sched-pipe.c index 0c7454f8b8a9..15911e9c587a 100644 --- a/tools/perf/bench/sched-pipe.c +++ b/tools/perf/bench/sched-pipe.c @@ -56,13 +56,13 @@ int bench_sched_pipe(int argc, const char **argv, * causes error in building environment for perf */ int __used ret, wait_stat; - pid_t pid, retpid; + pid_t pid, retpid __used; argc = parse_options(argc, argv, options, bench_sched_pipe_usage, 0); - assert(!pipe(pipe_1)); - assert(!pipe(pipe_2)); + BUG_ON(pipe(pipe_1)); + BUG_ON(pipe(pipe_2)); pid = fork(); assert(pid >= 0); diff --git a/tools/perf/util/include/linux/kernel.h b/tools/perf/util/include/linux/kernel.h index b6842c1d02a8..4af9a10cc2d2 100644 --- a/tools/perf/util/include/linux/kernel.h +++ b/tools/perf/util/include/linux/kernel.h @@ -47,8 +47,12 @@ #endif #ifndef BUG_ON +#ifdef NDEBUG +#define BUG_ON(cond) do { if (cond) {} } while (0) +#else #define BUG_ON(cond) assert(!(cond)) #endif +#endif /* * Both need more care to handle endianness From ea251d51d2c7d7233790123227f787c477f567f5 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 3 Sep 2012 11:53:06 +0900 Subject: [PATCH 2/9] perf hists: Introduce perf_hpp for hist period printing Current hist print functions are messy because it has to consider many of command line options and the code doing that is scattered around to places. So when someone wants to add an option to manipulate the hist output it'd very easy to miss to update all of them in sync. And things getting worse as more options/features are added continuously. So I'd like to refactor them using hpp formats and move common code to ui/hist.c in order to make it easy to maintain and to add new features.
