The first one fixes gcc -x <language> syntax in various build-time tests, which icecream and possible other gcc wrappers did not understand (and yes, icecream is going to be fixed as well).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

It gets stuck sometimes, but hey, it works sometimes too! In time it should support perf.data based workloads, i.e. it should have a: -o filename Command line option that will produce a perf.data file that can then be used with 'perf trace' or any of the other perf tools (script, report, etc). It will also eventually have the set of functionalities described in the previous 'trace' prototype by Thomas Gleixner: "Announcing a new utility: 'trace'" http://lwn.net/Articles/415728/ Also planned is to have some of the features suggested in the comments of that LWN article.

The VDSO shared object is same for all process on a running system, so it makes no difference when we store it inside the tracer - perf. When [vdso] map memory is hit, we retrieve [vdso] DSO image and store it into temporary file. During the build-id processing phase, the [vdso] DSO image is stored in build-id db, and build-id reference is made inside perf.data. The build-id vdso file object is called '[vdso]'. We don't use temporary file name which gets removed when record is finished. During report phase the vdso build-id object is treated as any other build-id DSO object. Adding following API for vdso object: bool is_vdso_map(const char *filename) - returns true if the filename matches vdso map name struct dso *vdso__dso_findnew(struct list_head *head) - find/create proper vdso DSO object vdso__exit(void) - removes temporary VDSO image if there's any This change makes backtrace dwarf post unwind possible from [vdso] maps.

* | perf hists: Introduce perf_hpp for hist period printingNamhyung Kim2012-09-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* perf tools: Fix build error with bison 2.6Kirill A. Shutemov2012-07-251-0/+3
| | | | | | | | | | | | | | | | | | | | | Bison 2.6 started to generate parse_events_parse() declaration in header. In this case we have redundant redeclaration: util/parse-events.c:29:5: error: redundant redeclaration of ‘parse_events_parse’ [-Werror=redundant-decls] In file included from util/parse-events.c:14:0: util/parse-events-bison.h:99:5: note: previous declaration of ‘parse_events_parse’ was here cc1: all warnings being treated as errors Let's disable -Wredundant-decls for util/parse-events.c since it includes header we can't control.

* perf tools: Trivial build fixDavid Ahern2012-06-271-1/+1
| | | | | | | | | | | | | | | | | | | References to OUTPUT should not be followed by a '/'. When a build output directory is not specified for this case you get: gcc -o builtin-annotate.o -c ... -I/util ... which is wrong.

* perf ui/gtk: Add GTK info_bar widget to browser windowNamhyung Kim2012-06-191-0/+3
| | | | | | | | | | | | | | | | | The GtkInfoBar is a modern UI component to display messages without bothering the main window. It'll be used for showing a warning message. As the GtkInfoBar requires 2.18 (or newer) version of GTK+ library, add availability check to Makefile too.
