* perf tools: Use __maybe_used for unused variablesIrina Tirdea2012-09-1176-418/+498
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 tools: Back [vdso] DSO with real dataJiri Olsa2012-09-118-26/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Storing data for VDSO shared object, because we need it for the post unwind processing. 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.

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.

* perf tools: replace mkostemp with mkstempIrina Tirdea2012-09-081-1/+1
| | | | | | | | | | | | | | | | | | The mkostemp function is only available in glibc. This leads to compile error in Android, since bionic is derived from BSD. Replacing mkostemp with mkstemp. mkstemp is available on both glibc and bionic.

* perf tools: include missing pthread.h headerIrina Tirdea2012-09-082-0/+2
| | | | | | | | | | | | | | | | | | | pthread variables are used in some files without explicitely including pthread.h. This leads to compile errors on Android. e.g.: in annotate.h, error: unknown type name 'pthread_mutex_t' Including pthread.h explicitely in files that use it to have all definitions included.

* perf tools: fix missing winsize definitionIrina Tirdea2012-09-082-0/+2
| | | | | | | | | | | | | | | | | In Android, struct winsize is not defined in the headers already included in help.c. This leads to a compile error. Including termios.h fixes the compilation error since it defines struct winsize.
