2012-09-11perf tools: Use __maybe_used for unused variablesIrina Tirdea
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.

2012-09-08perf hists: Introduce perf_hpp for hist period printingNamhyung Kim
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.

2012-07-25perf tools: use XSI-complaint version of strerror_r() instead of GNU-specificKirill A. Shutemov
Perf uses GNU-specific version of strerror_r(). The GNU-specific strerror_r() returns a pointer to a string containing the error message. This may be either a pointer to a string that the function stores in buf, or a pointer to some (immutable) static string (in which case buf is unused). In glibc-2.16 GNU version was marked with attribute warn_unused_result. It triggers few warnings in perf: util/target.c: In function ‘perf_target__strerror’: util/target.c:114:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result] ui/browsers/hists.c: In function ‘hist_browser__dump’: ui/browsers/hists.c:981:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result] They are bugs.

2012-05-03perf annotate browser: More clearly separate columnsArnaldo Carvalho de Melo
The first column (columns in the near future) are for the per line event overhead(s), that only appear when they are not zero. To clearly separate it, add back a solid vertical line, with just one colour, not influenced by the per line overheads. Then have the addr/offset column, then optionally the dynamic (static in the future) jump->target arrows, if 'j' enables it. Then the instructions.

2012-05-02perf ui: Add gtk2 support into setup_browser()Namhyung Kim
Now setup_browser can handle gtk2 front-end so split the TUI code to ui/tui/setup.c in order to remove dependency. To this end, make ui__init/exit global symbols and take an argument. Also split gtk code to ui/gtk/setup.c.

Instead of trying to show the current loop by naively looking for the next backward jump, just use 'j' to toggle showing arrows connecting jump with its target. And do it for forward jumps as well.
