When compiling perf tool code with gcc 4.4.7 I'm getting following error: CC util/session.o cc1: warnings being treated as errors util/session.c: In function ‘perf_session_deliver_event’: tools/perf/util/include/linux/bitops.h:109: error: dereferencing pointer ‘p’ does break strict-aliasing rules tools/perf/util/include/linux/bitops.h:101: error: dereferencing pointer ‘p’ does break strict-aliasing rules util/session.c:697: note: initialized from here tools/perf/util/include/linux/bitops.h:101: note: initialized from here make[1]: *** [util/session.o] Error 1 make: *** [util/session.o] Error 2 The aliased types here are u64 and unsigned long pointers, which is safe for the find_first_bit processing. This error shows up for me only for gcc 4.4 on 32bit x86, even for -Wstrict-aliasing=3, while newer gcc are quiet and scream here for -Wstrict-aliasing={2,1}.

The gcc documentation offers workaround for valid aliasing by using __may_alias__ attribute: http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gcc/Type-Attributes.html Using this workaround for the find_first_bit function.

Commit 71ae8aac ("lib: introduce arch optimized hash library") added an include to <linux/hash.h> for setting up an architecture specific fast hash. Since perf includes directly the non-uapi kernel header, it cannot find <asm/hash.h> on non-x86 and thus prevents perf to be compiled on every architecture other than x86. The problem is the inclusion of <asm/hash.h> in hash.h that results in the following error originating from util/evlist.c: fatal error: asm/hash.h: No such file or directory This commit simply adds an empty <asm/hash.h> stub/file to fix the compile issue on non-x86 architectures. As perf does not use any of these new functions, it fixes the compilation and therefore seems to be the most appropriate solution to go with.

In __rb_erase_color(), we were always setting a node to black after exiting the main loop. And in one case, after fixing up the tree to satisfy all rbtree invariants, we were setting the current node to root just to guarantee a loop exit, at which point the root would be set to black. However this is not necessary, as the root of an rbtree is already known to be black. The only case where the color flip is required is when we exit the loop due to the current node being red, and it's easiest to just do the flip at that point instead of doing it after the loop.

perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.

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.

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>

This brings the support for DWARF cfi unwinding on perf post processing. Call frame informations are retrieved and then passed to libunwind that requests memory and register content from the applications. Adding unwind object to handle the user stack backtrace based on the user register values and user stack dump. The unwind object access the libunwind via remote interface and provides to it all the necessary data to unwind the stack. The unwind interface provides following function: unwind__get_entries And callback (specified in above function) to retrieve the backtrace entries: typedef int (*unwind_entry_cb_t)(struct unwind_entry *entry, void *arg); Signed-off-by: NJiri Olsa <jolsa@redhat.com> Original-patch-by: NFrederic Weisbecker <fweisbec@gmail.com> Cc: "Frank Ch.

This renames for_each_set_bit_cont() to for_each_set_bit_from() because it is analogous to list_for_each_entry_from() in list.h rather than list_for_each_entry_continue().

On ancient systems I get this build failure: util/../../../arch/x86/include/asm/unistd.h:67:29: error: asm/unistd_64.h: No such file or directory In file included from util/cache.h:7, from builtin-test.c:8: util/../perf.h: In function ‘sys_perf_event_open’:In file included from util/../perf.h:16 perf.h:170: error: ‘__NR_perf_event_open’ undeclared (first use in this function) The reason is that this old system does not have the split unistd.h headers yet, from which to pick up the syscall definitions. Add the syscall numbers to the already existing i386 and x86_64 blocks in perf.h, and also provide empty include file stubs. With this patch perf builds and works fine on 5 years old user-space as well.
