From 8bf98b89688c3d7ec071bf26d49761e38d846b47 Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Sat, 8 Sep 2012 08:35:51 +0300 Subject: 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/util/include/linux/kernel.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'tools/perf/util/include/linux/kernel.h') diff --git a/tools/perf/util/include/linux/kernel.h b/tools/perf/util/include/linux/kernel.h index b6842c1d02a..4af9a10cc2d 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 -- cgit v1.2.3-70-g09d2 From 86d5a70c1eeb3d35bcadc94753fd9651df8835a8 Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Tue, 11 Sep 2012 01:14:59 +0300 Subject: perf tools: Update types definitions for Android Some type definitions are missing from Android or are already defined in bionic and lead to redefinition errors.
