following improvements:
- Arch/OS/platform-specific files are now included/excluded via the
preprocessor, rather than via the build system. This is more consistent
(we use the pre-processor for small arch/OS/platform-specific chunks
within files) and makes the build system much simpler, as the sources for
all programs are the same on all platforms.
- Vast amounts of cut+paste Makefile.am code has been factored out. If a
new platform is implemented, you need to add 11 extra Makefile.am lines.
Previously it was over 100 lines.
- Vex has been autotoolised. Dependency checking now works in Vex (no more
incomplete builds). Parallel builds now also work. --with-vex no longer
works; it's little use and a pain to support. VEX/Makefile is still in
the Vex repository and gets overwritten at configure-time; it should
probably be renamed Makefile-gcc to avoid possible problems, such as
accidentally committing a generated Makefile. There's a bunch of hacky
copying to deal with the fact that autotools don't handle same-named files
in different directories. Julian plans to rename the files to avoid this
problem.
- Various small Makefile.am things have been made more standard automake
style, eg. the use of pkginclude/pkglib prefixes instead of rolling our
own.
- The existing five top-level Makefile.am include files have been
consolidated into three.
- Most Makefile.am files now are structured more clearly, with comment
headers separating sections, declarations relating to the same things next
to each other, better spacing and layout, etc.
- Removed the unused exp-ptrcheck/tests/x86 directory.
- Renamed some XML files.
- Factored out some duplicated dSYM handling code.
- Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting
Makefile.am files to be much more standard.
- Cleaned up m_coredump by merging a bunch of files that had been
overzealously separated.
The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude
the added Makefile.vex.am, or 997 once the hacky file copying for Vex is
removed. And the build system is much simpler.

please change these if you don't like what I've written, and merge the
changes to the 3.4.X branch.

caused by heap corruption by the client. Also clarified the FAQ about this.
Also updated the FAQ about decoding failures a little.

- It heavily refactors the code: uses better names for things, splits up
complex functions that behaved very differently depending on how they were
called, removes some redundancies, and generally makes it much simpler and
easier to follow.
- It adds lots of comments, both inline, and also a big explanatory one at
the top which makes it clear exactly how the leak checker works and also
exactly what is meant by definite, possible, and indirect leaks. It also
has some ideas for future improvements.
- All tabs have been converted to spaces.
It also improves the functionality:
- Previously if you did --leak-check=summary, indirect and suppressed
blocks were counted as definite leaks. Now they are done properly, and so
the summary results from --leak-check=summary match those from
--leak-check=yes.
- Previously, some possibly reachable blocks were miscategorised as
definitely reachable, because only the pointer to the block itself was
considered, not any preceding pointers in the chain. This is now fixed.
- Added memcheck/tests/leak-cases, which fully tests all the possible
combinations of directly/indirectly reachable and possibly/definitely
reachable.
And it improves the manual quite a bit, and the FAQ a little bit.
This doesn't fix the leak checker to handle MALLOCLIKE_BLOCK works that have
been taken from within malloc'd blocks, but I think I know how to do it and
hope to do so in a subsequent commit.
It also changes all instances of "<constant>memcheck</constant>" in the
Memcheck manual to "Memcheck", for consistency and because "Memcheck" is
easier to write. There's one similar case for DRD but I didn't change that.

'__libc_start_main', in Massif, m_debuginfo and m_stacktrace. As part of
this, --show-below-main is now visible to tools, and Massif pays attention
to it.
Improved the description of --show-below-main=yes in the manual.
Replaced some instances of "__libc_start_main" in the test *.exp files with
"(below main)", which is what will actually be seen. Also updated
scalar.stderr.exp*, which should make it get closer to actually passing.

wrote into the parent's output file even if %p was specified.
Josef, I think Callgrind does not have this bug, but you might want to say
something about forking in the manual, as I have done for Massif and
Cachegrind.

stacks. Instead of hardwiring the main thread stack to a max of 16MB
and segfaulting the app beyond that point, allow the user to specify
the main stack size using the new flag --main-stacksize=<number>.
If said flag is not present, the current default, which is "MIN(16GB,
current ulimit -s value)", is used.

on some advanced aspects of the core (client requests, function
wrapping) and move stuff from the main core manual into it.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@7208
somewhat to move less relevant material out of the way to some extent.
The main changes are:
* Update date and version info
* Mention other tools in the quick-start guide
* Document --child-silent-after-fork
* Rearrange order of sections in the Valgrind Core chapter, to move
advanced stuff (client requests) to the end, and compact stuff
relevant to the majority of users towards the front
* Move MPI debugging stuff from the Core manual (a nonsensical place
for it) to the Memcheck chapter
* Update the manual's introductory chapter a bit
* Connect up new tech docs summary page, and disconnect old and
very out of date valgrind/memcheck tech docs
* Add section tags to the Cachegrind manual, to stop xsltproc
complaining about their absence
