-# Also: in newer versions of automake (1.10 onwards?) asm files ending with

+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
+bugzilla ( rather
+than mailing the developers (or mailing lists) directly -- bugs that
+are not entered into bugzilla tend to get forgotten about or ignored.

+where XXXXXX is the bug number as listed below.

 (3.4.0:       3 Jan 2009, vex r1878, valgrind r8899).
-Release 3.3.1 (4 June 2008)
-3.3.1 fixes a bunch of bugs in 3.3.0, adds support for glibc-2.8 based
-systems (openSUSE 11, Fedora Core 9), improves the existing glibc-2.7
-support, and adds support for the SSSE3 (Core 2) instruction set.
-3.3.1 will likely be the last release that supports some very old
-systems.  In particular, the next major release, 3.4.0, will drop
-support for the old LinuxThreads threading library, and for gcc
-versions prior to 3.0.
-The fixed bugs are as follows.  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.
