perf is currently including magic.h directly from the kernel. If the glibc magic.h is also included, this leads to warnings that the constants are redefined. This happens on some systems (e.g. Android). Redefinition errors on Android: In file included from util/util.h:79:0, from util/cache.h:5, from util/abspath.c:1: util/../../../include/linux/magic.h:5:0: error: "AFFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:53:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:19:0: error: "EFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:61:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:26:0: error: "HPFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:67:0: note: this is the location of the previous definition Only two constants from magic.h are used by perf (DEBUGFS_MAGIC and SYSFS_MAGIC). This fix provides a wrapper for magic.h that includes only these constants instead of including the kernel header file directly.

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.

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: NPeter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: NIrina Tirdea <irina.tirdea@intel.com> Reviewed-by: NNamhyung Kim <namhyung@kernel.org> Reviewed-by: NPekka 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.comSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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. This can also help in debugging since it offers the possibility to turn on/off printing the backtrace.

Noticed while developing a 'perf test' entry to verify that perf_evsel__name works.

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.

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.

For checking return value of the strdup, 'event' should be 'evsel'.

When analyzing perf data from hosts of other architecture than one of the local host it's useful to call objdump that is part of a toolchain for that architecture. Instead of calling regular objdump, call one that user specified in command line.

mempcpy is not supported by bionic in Android and will lead to compilation errors. Replacing mempcpy with memcpy so it will work in Android.

Like others, the numbers can be saved in a different endian format than a host machine. Swap them if needed.
