Irina Tirdea c9f08bee50 perf tools: add NO_BACKTRACE for application self-debugging 
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.

Irina Tirdea b771a83062 perf tools: include basename for non-glibc systems 
perf uses the glibc version of basename(), by defining _GNU_SOURCE,
including string.h and not including libgen.h. The glibc version of
basename is better than the POSIX version since it does not modify its
argument.

Android has only one version of basename which is defined in libgen.h.
This version is the same as the glibc version.

Error on Android:
util/annotate.c: In function 'symbol__annotate_printf':
util/annotate.c:503:3: error: implicit declaration of function 'basename'
[-Werror=implicit-function-declaration]
util/annotate.c:503:3: error: nested extern declaration of 'basename'
[-Werror=nested-externs]
util/annotate.c:503:14: error: assignment makes pointer from integer without
a cast [-Werror]

On Android libgen.h should be included to define basename.

Jiri Olsa 863e451f69 perf diff: Make diff command work with evsel hists 
Putting 'perf diff' command back on track with the 'latest'
evsel hists changes. Each evsel has its own 'hists' object
gathering stats for the particular event.

While currently counts are accumulated for the whole session
regardless of the events diversification within compared
sessions.

The 'perf diff' command now outputs all matching events within
compared sessions (with event name specified). The per event
diff output stays the same.

There are three cases that call die() in the pretty_print.

 1. insufficient number of argument: cannot proceed anymore.
 2. too long format conversion specifier: truncate and proceed.
 3. bad size specifier in format string: skip and proceed.

For all cases, convert die to do_warning, mark the event as
EVENT_FL_FAILED and print error message at the last.

Arnaldo Carvalho de Melo 8ad7013b25 perf test: Add round trip test for sw and hw event names 
It basically traverses the hardware and software event name arrays
creating an evlist with all events, then it uses perf_evsel__name to
check that the name is the expected one.

With it I noticed this problem:

[root@sandy ~]# perf test 10
10: roundtrip evsel->name check:invalid or unsupported event: 'CPU-migrations'
Run 'perf list' for a list of valid events
 FAILED!

Changed it to "cpu-migrations" in the software event arrays and it
worked.

This is to catch problems like the one reported by Joel Uckelman in
http://permalink.gmane.org/gmane.linux.kernel.perf.user/1016

Hardware cache events will be checked in the following patch.

Namhyung Kim 831394bdd9 perf header: Prepare tracepoint events regardless of name 
Current perf_evlist__set_tracepoint_names is a misnomer because it finds

it when a event has set name already caused a trouble.

Rename it and set name only a event doesn't have one.

Maciek Borzecki 7a4ec93885 perf tools: Allow user to indicate path to objdump in command line 
When analyzing perf data from hosts of other architecture than one of
the local host it's useful to call objdump that is part of a toolchain
for that architecture. Instead of calling regular objdump, call one that
user specified in command line.
