Log Message:
Update valgrind from ancient 2.4.0 to the latest 3.8.1.

The full list of changes is too big to be listed here,
only changes in the current 3.8 are listed below.
For a full list for changes see

Release 3.8.1 (19 September 2012)
3.8.1 is a bug fix release.  It fixes some assertion failures in 3.8.0
that occur moderately frequently in real use cases, adds support for
some missing instructions on ARM, and fixes a deadlock condition on
MacOSX.  If you package or deliver 3.8.0 for others to use, you might
want to consider upgrading to 3.8.1 instead.

The following bugs have been fixed or resolved.  Note that "n-i-bz"
stands for "not in bugzilla" -- that is, a bug that was reported to us
but never got a bugzilla entry.  We encourage you to file bugs in
bugzilla ( rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.

Release 3.8.0 (10 August 2012)
3.8.0 is a feature release with many improvements and the usual
collection of bug fixes.

This release supports X86/Linux, AMD64/Linux, ARM/Linux, PPC32/Linux,
PPC64/Linux, S390X/Linux, MIPS/Linux, ARM/Android, X86/Android,
X86/MacOSX 10.6/10.7 and AMD64/MacOSX 10.6/10.7.  Support for recent
distros and toolchain components (glibc 2.16, gcc 4.7) has been added.
There is initial support for MacOSX 10.8, but it is not usable for
serious work at present.

* ================== PLATFORM CHANGES =================

* Support for MIPS32 platforms running Linux.  Valgrind has been
  tested on MIPS32 and MIPS32r2 platforms running different Debian
  Squeeze and MeeGo distributions.  Both little-endian and big-endian
  cores are supported.  The tools Memcheck, Massif and Lackey have
  been tested and are known to work. See README.mips for more details.

* Preliminary support for Android running on x86.

* Preliminary (as-yet largely unusable) support for MacOSX 10.8.

* Support for Intel AVX instructions and for AES instructions.  This
  support is available only for 64 bit code.

* Support for POWER Decimal Floating Point instructions.

* ==================== TOOL CHANGES ====================

* Non-libc malloc implementations are now supported.  This is useful
  for tools that replace malloc (Memcheck, Massif, DRD, Helgrind).
  Using the new option --soname-synonyms, such tools can be informed
  that the malloc implementation is either linked statically into the
  executable, or is present in some other shared library different
  from  This makes it possible to process statically linked
  programs, and programs using other malloc libraries, for example
  TCMalloc or JEMalloc.

* For tools that provide their own replacement for malloc et al, the
  option --redzone-size=<number> allows users to specify the size of
  the padding blocks (redzones) added before and after each client
  allocated block.  Smaller redzones decrease the memory needed by
  Valgrind.  Bigger redzones increase the chance to detect blocks
  overrun or underrun.  Prior to this change, the redzone size was
  hardwired to 16 bytes in Memcheck.

* Memcheck:

  - The leak_check GDB server monitor command now can
    control the maximum nr of loss records to output.

  - Reduction of memory use for applications allocating
    many blocks and/or having many partially defined bytes.

  - Addition of GDB server monitor command 'block_list' that lists
    the addresses/sizes of the blocks of a leak search loss record.

  - Addition of GDB server monitor command 'who_points_at' that lists
    the locations pointing at a block.

  - If a redzone size > 0 is given, VALGRIND_MALLOCLIKE_BLOCK now will
    detect an invalid access of these redzones, by marking them
    noaccess.  Similarly, if a redzone size is given for a memory
    pool, VALGRIND_MEMPOOL_ALLOC will mark the redzones no access.
    This still allows to find some bugs if the user has forgotten to
    mark the pool superblock noaccess.

  - Performance of memory leak check has been improved, especially in
    cases where there are many leaked blocks and/or many suppression
    rules used to suppress leak reports.

  - Reduced noise (false positive) level on MacOSX 10.6/10.7, due to
    more precise analysis, which is important for LLVM/Clang
    generated code.  This is at the cost of somewhat reduced
    performance.  Note there is no change to analysis precision or
    costs on Linux targets.

* DRD:

  - Added even more facilities that can help finding the cause of a data
    race, namely the command-line option --ptrace-addr and the macro
    DRD_STOP_TRACING_VAR(x). More information can be found in the manual.

  - Fixed a subtle bug that could cause false positive data race reports.

* ==================== OTHER CHANGES ====================

* The C++ demangler has been updated so as to work well with C++
  compiled by up to at least g++ 4.6.

* Tool developers can make replacement/wrapping more flexible thanks
  to the new option --soname-synonyms.  This was reported above, but
  in fact is very general and applies to all function
  replacement/wrapping, not just to malloc-family functions.

* Round-robin scheduling of threads can be selected, using the new
  option --fair-sched= yes.  Prior to this change, the pipe-based
  thread serialisation mechanism (which is still the default) could
  give very unfair scheduling.  --fair-sched=yes improves
  responsiveness of interactive multithreaded applications, and
  improves repeatability of results from the thread checkers Helgrind
  and DRD.

* For tool developers: support to run Valgrind on Valgrind has been
  improved.  We can now routinely Valgrind on Helgrind or Memcheck.

* gdbserver now shows the float shadow registers as integer
  rather than float values, as the shadow values are mostly
  used as bit patterns.

* Increased limit for the --num-callers command line flag to 500.

* Performance improvements for error matching when there are many
  suppression records in use.

* Improved support for DWARF4 debugging information (bug 284184).

* Initial support for DWZ compressed Dwarf debug info.

* Improved control over the IR optimiser's handling of the tradeoff
  between performance and precision of exceptions.  Specifically,
  --vex-iropt-precise-memory-exns has been removed and replaced by
  --vex-iropt-register-updates, with extended functionality.  This
  allows the Valgrind gdbserver to always show up to date register
  values to GDB.

* Modest performance gains through the use of translation chaining for
  JIT-generated code.

* ==================== FIXED BUGS ====================

The following bugs have been fixed or resolved.  Note that "n-i-bz"
stands for "not in bugzilla" -- that is, a bug that was reported to us
but never got a bugzilla entry.  We encourage you to file bugs in
