Andi Kleen 7ddc2710b9 Add profile feedback build to git Add a gcc profile feedback build option "profile-all" to the main Makefile. It simply runs the test suite to generate feedback data and the recompiles the main executables with that. The basic structure is similar to the existing gcov code. gcc is often able to generate better code with profile feedback data. The training load also doesn't need to be too similar to the actual load, it still gives benefits. The test suite run is unfortunately quite long. It would be good to find a suitable subset that runs faster and still gives reasonable feedback. For now the test suite runs single threaded (I had some trouble running the test suite with -jX) I tested it with git gc and git blame kernel/sched.c on a Linux kernel tree. For gc I get about 2.7% improvement in wall clock time by using the feedback build, for blame about 2.4%. That's not gigantic, but not shabby either for a very small patch. If anyone has any favourite CPU intensive git benchmarks feel free to try them too. I hope distributors will switch to use a feedback build in their packages.

	GIT - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, depending on your mood.

 - random three-letter combination that is pronounceable, and not
   actually used by any common UNIX command.  The fact that it is a
   mispronunciation of "get" may or may not be relevant.
 - stupid. contemptible and despicable. simple. Take your pick from the
   dictionary of slang.
 - "global information tracker": you're in a good mood, and it actually
   works for you. Angels sing, and a light suddenly fills the room.
 - "goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.

Please read the file INSTALL for installation instructions.

See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".

CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).

Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.

The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org. To subscribe
to the list, send an email with just "subscribe git" in the body to
majordomo@vger.kernel.org. The mailing list archives are available at
http://marc.theaimsgroup.com/?l=git and other archival sites.

The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
