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.

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:

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.

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.

commit ee8dd3ca43
causes a double free during a probe deletion as the node is never
removed from the list via strlist__remove(), even though it gets
'deleted' (read free()'d). This causes a double free when we do
strlist__delete() as the node is already deleted but present in the
rblist.
[suzukikp@suzukikp perf]$ sudo ./perf probe -a do_fork
Added new event:
probe:do_fork (on do_fork)
You can now use it in all perf tools, such as:
perf record -e probe:do_fork -aR sleep 1
[suzukikp@suzukikp perf]$ sudo ./perf probe -d do_fork
Removed event: probe:do_fork

Make sure we remove the node from the rblist before we delete the node.
The rblist__remove_node() will invoke rblist->node_delete, which will
take care of deleting the node with the suitable function provided by

With dynamic pmu allocation there are also dynamically assigned pmu ids.
These ids are used in event->attr.type to describe the pmu to be used
for that event. The information is available in sysfs, e.g:
/sys/bus/event_source/devices/breakpoint/type: 5
/sys/bus/event_source/devices/cpu/type: 4
/sys/bus/event_source/devices/ibs_fetch/type: 6
/sys/bus/event_source/devices/ibs_op/type: 7
/sys/bus/event_source/devices/software/type: 1
/sys/bus/event_source/devices/tracepoint/type: 2
These mappings are needed to know which samples belong to which pmu. If
a pmu is added dynamically like for ibs_fetch or ibs_op the type value
may vary.
Now, when decoding samples from perf.data this information in sysfs
might be no longer available or may have changed. We need to store it in
perf.data. Using the header for this. Now the header information created
with perf report contains an additional section looking like this:
# pmu mappings: ibs_op = 7, ibs_fetch = 6, cpu = 4, breakpoint = 5, tracepoint = 2, software = 1

Use command line string provided by the -e option to name events. This
way we get unique events names that also support pmu event syntax
(<pmu_name>/<config>/<modifier>). No need to reconstruct the name
anymore from its attributes. We use the event_desc of the header to
store the name in the perf.data header. Thus it is also available for
perf report.
Implemented by putting the parser in different states to parse events or
configs.
And since event names are now generated from the command line
specification. Update event names in test cases accordingly.

When we use a separate output directory, we add util/ to the include
path for the generated C files. However, this is currently added to the
end of the path, behind /usr/include/slang and /usr/include/gtk-2.0 if
use of the respective libraries is enabled. Thus the '#include
"../perf.h"' in util/parse-events.l can actually include
/usr/include/perf.h if it exists.
Move '-Iutil/' ahead of all the other preprocessor options.

If GTK2 development packages are not installed, make is rather noisy:

Currently the gtk_main_quit() is called twice when perf exits so the
following warning is emitted:
[penberg@tux perf]$ ./perf report --gtk
^Cperf: Interrupt
(perf:4048): Gtk-CRITICAL **: IA__gtk_main_quit: assertion `main_loops != NULL' failed
Fix it by not to call it unnecessarily.

Trivial patch that renames global variable 'events' in util/header.c.
Use a more specific naming to avoid conflicts. Same for variable
'event_count'.

Trivial patch to improve understanding of code.
Varible attr is usually used for struct perf_event_attr. Using it in a
different context is irritating. Thus, renaming it.

Use same type for ids everywhere.
In case of writing to perf.data the size is u32. In pipe mode it is
limited to header.size (less than u16). Adding a size check here.
Size overflow due to casting shouldn't actually happen in practice, but
during development this may cause type missmatch warninngs/errors,
unifying types avoids this.
