Frederic Weisbecker 1902efe7f6 perf tools: Add new COMM infrastructure
This new COMM infrastructure provides two features:

1) It keeps track of all comms lifecycle for a given thread. This way we
can associate a timeframe to any thread COMM, as long as
PERF_SAMPLE_TIME samples are joined to COMM and fork events.

As a result we should have more precise COMM sorted hists with seperated
entries for pre and post exec time after a fork.

2) It also makes sure that a given COMM string is not duplicated but
rather shared among the threads that refer to it. This way the threads
COMM can be compared against pointer values from the sort
infrastructure.

Ingo Molnar 8a5411e9a3 perf tools: Implement summary output for 'make install'
'make install' used to show all the install lines, which is way too
verbose to be really informative to the user.

Implement summary output instead:

    SUBDIR   Documentation

    INSTALL  libexec

    INSTALL  bash_completion-script

Ingo Molnar 65fb09922d tools: Harmonize the various build messages in perf, lib-traceevent, lib-lk
The various build lines from libtraceevent and perf mix up during a
parallel build and produce unaligned output like:

    CC builtin-buildid-list.o
    CC builtin-buildid-cache.o
    CC builtin-list.o
  CC FPIC            trace-seq.o
    CC builtin-record.o
  CC FPIC            parse-filter.o
    CC builtin-report.o
    CC builtin-stat.o
  CC FPIC            parse-utils.o
  CC FPIC            kbuffer-parse.o
    CC builtin-timechart.o
    CC builtin-top.o
    CC builtin-script.o
  BUILD STATIC LIB   libtraceevent.a
    CC builtin-probe.o
    CC builtin-kmem.o
    CC builtin-lock.o

To solve this, harmonize all the build message alignments to be similar
to the kernel's kbuild output: prefixed by two spaces and 11-char wide.

After the patch the output looks pretty tidy, even if output lines get
mixed up:

  CC      builtin-annotate.o
  FLAGS:  * new build flags or cross compiler
  CC      builtin-bench.o
  AR      liblk.a
  CC      bench/sched-messaging.o
  CC FPIC event-parse.o
  CC      bench/sched-pipe.o
  CC FPIC trace-seq.o
  CC      bench/mem-memcpy.o
  CC      bench/mem-memset.o
  CC FPIC parse-filter.o
  CC      builtin-diff.o
  CC      builtin-evlist.o
  CC      builtin-help.o

Ingo Molnar 1f7c645ab4 tools/perf/build: Fix O=/some/dir perf.o type of targets
If someone specifies a single target, mixed with O=, the following way:

    hubble:~/tip/tools/perf> make O=/tmp/perf util/stat.o
    BUILD: Doing 'make -j8' parallel build
    gcc  -Wbad-function-cast -Wdeclaration-after-statement -Wformat-security -Wformat-y2k [...]

The build might even fail, if a target depends on other targets:

    hubble:~/tip/tools/perf> make O=/tmp/perf perf.o
    ...
    perf.c: In function ‘handle_options’:
    perf.c:155:21: error: ‘PERF_HTML_PATH’ undeclared (first use in this function)

The correct way to invoke such targets is:

    hubble:~/tip/tools/perf> make O=/tmp/perf /tmp/perf/perf.o
    BUILD: Doing 'make -j8' parallel build
    GEN /tmp/perf/common-cmds.h
    CC /tmp/perf/perf.o

But that's unnecessary typing and it's also easy to mistakenly build into the
source directory.

To fix this remove the generic suffix rules and add redirection to $(OUTPUT)
for the most popular .o targets.
