Linux native exit codes are 8-bit unsigned values. exit(-1) results in an exit code of 255, which is usually reserved for shells reporting 'command not found'. Use the portable value EXIT_FAILURE.

2012-09-08perf hists: Introduce perf_hpp for hist period printingNamhyung Kim
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.

2012-09-08perf bench: fix assert when NDEBUG is definedIrina Tirdea
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 <a.p.zijlstra@chello.nl> Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Reviewed-by: Namhyung Kim <namhyung@kernel.org> Reviewed-by: Pekka Enberg <penberg@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Namhyung Kim <namhyung.kim@lge.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/1347082551-2394-1-git-send-email-irina.tirdea@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2012-09-07perf tools: add NO_BACKTRACE for application self-debuggingIrina Tirdea
perf has support for self-debugging by defining dump_stack function. This function uses backtrace and backtrace_symbols functions defined as GNU extensions. In Android, bionic does not offer support for these functions and compilation will fail with the following error: target C: libperf <= tools/perf/util/util.c tools/perf/util/util.c:4:22: fatal error: execinfo.h: No such file or directory compilation terminated. Add a compile-time option (NO_BACKTRACE) to enable or disable self-debugging functionality in perf.

2012-09-06perf test: Add round trip test for sw and hw event namesArnaldo Carvalho de Melo
It basically traverses the hardware and software event name arrays creating an evlist with all events, then it uses perf_evsel__name to check that the name is the expected one. With it I noticed this problem: [root@sandy ~]# perf test 10 10: roundtrip evsel->name check:invalid or unsupported event: 'CPU-migrations' Run 'perf list' for a list of valid events FAILED! Changed it to "cpu-migrations" in the software event arrays and it worked. This is to catch problems like the one reported by Joel Uckelman in http://permalink.gmane.org/gmane.linux.kernel.perf.user/1016 Hardware cache events will be checked in the following patch.

2012-09-06perf header: Prepare tracepoint events regardless of nameNamhyung Kim
Current perf_evlist__set_tracepoint_names is a misnomer because it finds and sets correspoding event_format in addition to the name. So skipping it when a event has set name already caused a trouble. Rename it and set name only a event doesn't have one.
