Release 3.14.0 (?? ????????? 201?)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--
Release 3.14.0 is under development, not yet released.
3.14.0 is a feature release with many improvements and the usual collection of
bug fixes.
This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,
MIPS64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android,
X86/Solaris, AMD64/Solaris and AMD64/MacOSX 10.12.
* ==================== CORE CHANGES ===================
* ================== PLATFORM CHANGES =================
* ==================== TOOL CHANGES ====================
* ==================== OTHER CHANGES ====================
* ==================== 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 (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.
To see details of a given bug, visit
https://bugs.kde.org/show_bug.cgi?id=XXXXXX
where XXXXXX is the bug number as listed below.
380397 s390x: __GI_strcspn() replacemenet needed

Release 3.13.0 (15 June 2017)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.13.0 is a feature release with many improvements and the usual collection of
bug fixes.
This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,
MIPS64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android,
X86/Solaris, AMD64/Solaris and AMD64/MacOSX 10.12.
* ==================== CORE CHANGES ===================
* The translation cache size has been increased to keep up with the demands of
large applications. The maximum number of sectors has increased from 24 to
48. The default number of sectors has increased from 16 to 32 on all
targets except Android, where the increase is from 6 to 12.
* The amount of memory that Valgrind can use has been increased from 64GB to
128GB. In particular this means your application can allocate up to about
60GB when running on Memcheck.
* Valgrind's default load address has been changed from 0x3800'0000 to
0x5800'0000, so as to make it possible to load larger executables. This
should make it possible to load executables of size at least 1200MB.
* A massive spaceleak caused by reading compressed debuginfo files has been
fixed. Valgrind should now be entirely usable with gcc-7.0 "-gz" created
debuginfo.
* The C++ demangler has been updated.
* Support for demangling Rust symbols has been added.
* A new representation of stack traces, the "XTree", has been added. An XTree
is a tree of stacktraces with data associated with the stacktraces. This is
used by various tools (Memcheck, Helgrind, Massif) to report on the heap
consumption of your program. Reporting is controlled by the new options
--xtree-memory=none|allocs|full and --xtree-memory-file=<file>.
A report can also be produced on demand using the gdbserver monitor command
'xtmemory [<filename>]>'. The XTree can be output in 2 formats: 'callgrind
format' and 'massif format. The existing visualisers for these formats (e.g.
callgrind_annotate, KCachegrind, ms_print) can be used to visualise and
analyse these reports.
Memcheck can also produce XTree leak reports using the Callgrind file
format. For more details, see the user manual.
* ================== PLATFORM CHANGES =================
* ppc64: support for ISA 3.0B and various fixes for existing 3.0 support
* amd64: fixes for JIT failure problems on long AVX2 code blocks
* amd64 and x86: support for CET prefixes has been added
* arm32: a few missing ARMv8 instructions have been implemented
* arm64, mips64, mips32: an alternative implementation of Load-Linked and
Store-Conditional instructions has been added. This is to deal with
processor implementations that implement the LL/SC specifications strictly
and as a result cause Valgrind to hang in certain situations. The
alternative implementation is automatically enabled at startup, as required.
You can use the option --sim-hints=fallback-llsc to force-enable it if you
want.
* Support for OSX 10.12 has been improved.
* On Linux, clone handling has been improved to honour CLONE_VFORK that
involves a child stack. Note however that CLONE_VFORK | CLONE_VM is handled
like CLONE_VFORK (by removing CLONE_VM), so applications that depend on
CLONE_VM exact semantics will (still) not work.
* The TileGX/Linux port has been removed because it appears to be both unused
and unsupported.
* ==================== TOOL CHANGES ====================
* Memcheck:
- Memcheck should give fewer false positives when running optimised
Clang/LLVM generated code.
- Support for --xtree-memory and 'xtmemory [<filename>]>'.
- New command line options --xtree-leak=no|yes and --xtree-leak-file=<file>
to produce the end of execution leak report in a xtree callgrind format
file.
- New option 'xtleak' in the memcheck leak_check monitor command, to produce
the leak report in an xtree file.
* Massif:
- Support for --xtree-memory and 'xtmemory [<filename>]>'.
- For some workloads (typically, for big applications), Massif memory
consumption and CPU consumption has decreased significantly.
* Helgrind:
- Support for --xtree-memory and 'xtmemory [<filename>]>'.
- addition of client request VALGRIND_HG_GNAT_DEPENDENT_MASTER_JOIN, useful
for Ada gnat compiled applications.
* ==================== OTHER CHANGES ====================
* For Valgrind developers: in an outer/inner setup, the outer Valgrind will
append the inner guest stacktrace to the inner host stacktrace. This helps
to investigate the errors reported by the outer, when they are caused by the
inner guest program (such as an inner regtest). See README_DEVELOPERS for
more info.
* To allow fast detection of callgrind files by desktop environments and file
managers, the format was extended to have an optional first line that
uniquely identifies the format ("# callgrind format"). Callgrind creates
this line now, as does the new xtree functionality.
* File name template arguments (such as --log-file, --xtree-memory-file, ...)
have a new %n format letter that is replaced by a sequence number.
* "--version -v" now shows the SVN revision numbers from which Valgrind was
built.
* ==================== FIXED BUGS ====================
The following bugs have been fixed or resolved. Note that "n-i-bz"

Release 3.12.0 (20 October 2016)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.12.0 is a feature release with many improvements and the usual
collection of bug fixes.
This release supports X86/Linux, AMD64/Linux, ARM32/Linux,
ARM64/Linux, PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux,
MIPS32/Linux, MIPS64/Linux, ARM/Android, ARM64/Android,
MIPS32/Android, X86/Android, X86/Solaris, AMD64/Solaris, X86/MacOSX
10.10 and AMD64/MacOSX 10.10. There is also preliminary support for
X86/MacOSX 10.11/12, AMD64/MacOSX 10.11/12 and TILEGX/Linux.
* ================== PLATFORM CHANGES =================
* POWER: Support for ISA 3.0 has been added
* mips: support for O32 FPXX ABI has been added.
* mips: improved recognition of different processors
* mips: determination of page size now done at run time
* amd64: Partial support for AMD FMA4 instructions.
* arm, arm64: Support for v8 crypto and CRC instructions.
* Improvements and robustification of the Solaris port.
* Preliminary support for MacOS 10.12 (Sierra) has been added.
Whilst 3.12.0 continues to support the 32-bit x86 instruction set, we
would prefer users to migrate to 64-bit x86 (a.k.a amd64 or x86_64)
where possible. Valgrind's support for 32-bit x86 has stagnated in
recent years and has fallen far behind that for 64-bit x86
instructions. By contrast 64-bit x86 is well supported, up to and
including AVX2.
* ==================== TOOL CHANGES ====================
* Memcheck:
- Added meta mempool support for describing a custom allocator which:
- Auto-frees all chunks assuming that destroying a pool destroys all
objects in the pool
- Uses itself to allocate other memory blocks
- New flag --ignore-range-below-sp to ignore memory accesses below
the stack pointer, if you really have to. The related flag
--workaround-gcc296-bugs=yes is now deprecated. Use
--ignore-range-below-sp=1024-1 as a replacement.
* DRD:
- Improved thread startup time significantly on non-Linux platforms.
* DHAT
- Added collection of the metric "tot-blocks-allocd"
* ==================== OTHER CHANGES ====================
* Replacement/wrapping of malloc/new related functions is now done not just
for system libraries by default, but for any globally defined malloc/new
related function (both in shared libraries and statically linked alternative
malloc implementations). The dynamic (runtime) linker is excluded, though.
To only intercept malloc/new related functions in
system libraries use --soname-synonyms=somalloc=nouserintercepts (where
"nouserintercepts" can be any non-existing library name).
This new functionality is not implemented for MacOS X.
* The maximum number of callers in a suppression entry is now equal to
the maximum size for --num-callers (500).
Note that --gen-suppressions=yes|all similarly generates suppressions
containing up to --num-callers frames.
* New and modified GDB server monitor features:
- Valgrind's gdbserver now accepts the command 'catch syscall'.
Note that you must have GDB >= 7.11 to use 'catch syscall' with
gdbserver.
* New option --run-cxx-freeres=<yes|no> can be used to change whether
__gnu_cxx::__freeres() cleanup function is called or not. Default is
'yes'.
* Valgrind is able to read compressed debuginfo sections in two formats:
- zlib ELF gABI format with SHF_COMPRESSED flag (gcc option -gz=zlib)
- zlib GNU format with .zdebug sections (gcc option -gz=zlib-gnu)
* Modest JIT-cost improvements: the cost of instrumenting code blocks
for the most common use case (x86_64-linux, Memcheck) has been
reduced by 10%-15%.
* Improved performance for programs that do a lot of discarding of
instruction address ranges of 8KB or less.
* The C++ symbol demangler has been updated.
* More robustness against invalid syscall parameters on Linux.
* ==================== 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 (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.

facility. The oldest supported machine model is z990.
* x86: on an SSE2 only host, Valgrind in 32 bit mode now claims to be a
Pentium 4. 3.10.1 wrongly claimed to be a Core 2, which is SSSE3.
* The JIT's register allocator is significantly faster, making the JIT
as a whole somewhat faster, so JIT-intensive activities, for example
program startup, are modestly faster, around 5%.
* There have been changes to the default settings of several command
line flags, as detailed below.
* Intel AVX2 support is more complete (64 bit targets only). On AVX2
capable hosts, the simulated CPUID will now indicate AVX2 support.
* ==================== TOOL CHANGES ====================
* Memcheck:
- The default value for --leak-check-heuristics has been changed from
"none" to "all". This helps to reduce the number of possibly
lost blocks, in particular for C++ applications.
- The default value for --keep-stacktraces has been changed from
"malloc-then-free" to "malloc-and-free". This has a small cost in
memory (one word per malloc-ed block) but allows Memcheck to show the
3 stacktraces of a dangling reference: where the block was allocated,
where it was freed, and where it is acccessed after being freed.
- The default value for --partial-loads-ok has been changed from "no" to
"yes", so as to avoid false positive errors resulting from some kinds
of vectorised loops.
- A new monitor command 'xb <addr> <len>' shows the validity bits of
<len> bytes at <addr>. The monitor command 'xb' is easier to use
than get_vbits when you need to associate byte data value with
their corresponding validity bits.
- The 'block_list' monitor command has been enhanced:
o it can print a range of loss records
o it now accepts an optional argument 'limited <max_blocks>'
to control the number of blocks printed.
o if a block has been found using a heuristic, then
'block_list' now shows the heuristic after the block size.
o the loss records/blocks to print can be limited to the blocks
found via specified heuristics.
- The C helper functions used to instrument loads on
x86-{linux,solaris} and arm-linux (both 32-bit only) have been
replaced by handwritten assembly sequences. This gives speedups
in the region of 0% to 7% for those targets only.
- A new command line option, --expensive-definedness-checks=yes|no,
has been added. This is useful for avoiding occasional invalid
uninitialised-value errors in optimised code. Watch out for
runtime degradation, as this can be up to 25%. As always, though,
the slowdown is highly application specific. The default setting
is "no".
* Massif:
- A new monitor command 'all_snapshots <filename>' dumps all
snapshots taken so far.
* Helgrind:
- Significant memory reduction and moderate speedups for
--history-level=full for applications accessing a lot of memory
with many different stacktraces.
- The default value for --conflict-cache-size=N has been doubled to
2000000. Users that were not using the default value should
preferably also double the value they give.
The default was changed due to the changes in the "full history"
implementation. Doubling the value gives on average a slightly more
complete history and uses similar memory (or significantly less memory
in the worst case) than the previous implementation.
- The Helgrind monitor command 'info locks' now accepts an optional
argument 'lock_addr', which shows information about the lock at the
given address only.
- When using --history-level=full, the new Helgrind monitor command
'accesshistory <addr> [<len>]' will show the recorded accesses for
<len> (or 1) bytes at <addr>.
* ==================== OTHER CHANGES ====================
* The default value for the --smc-check option has been changed from
"stack" to "all-non-file" on targets that provide automatic D-I
cache coherence (x86, amd64 and s390x). The result is to provide,
by default, transparent support for JIT generated and self-modifying
code on all targets.
* Mac OS X only: the default value for the --dsymutil option has been
changed from "no" to "yes", since any serious usage on Mac OS X
always required it to be "yes".
* The command line options --db-attach and --db-command have been removed.
They were deprecated in 3.10.0.
* When a process dies due to a signal, Valgrind now shows the signal
and the stacktrace at default verbosity (i.e. verbosity 1).
* The address description logic used by Memcheck and Helgrind now
describes addresses in anonymous segments, file mmap-ed segments,
shared memory segments and the brk data segment.
* The new option --error-markers=<begin>,<end> can be used to mark the
begin/end of errors in textual output mode, to facilitate
searching/extracting errors in output files that mix valgrind errors
with program output.
* The new option --max-threads=<number> can be used to change the number
of threads valgrind can handle. The default is 500 threads which
should be more than enough for most applications.
* The new option --valgrind-stacksize=<number> can be used to change the
size of the private thread stacks used by Valgrind. This is useful
for reducing memory use or increasing the stack size if Valgrind
segfaults due to stack overflow.
* The new option --avg-transtab-entry-size=<number> can be used to specify
the expected instrumented block size, either to reduce memory use or
to avoid excessive retranslation.
* Valgrind can be built with Intel's ICC compiler, version 14.0 or later.
* New and modified GDB server monitor features:
- When a signal is reported in GDB, you can now use the GDB convenience
variable $_siginfo to examine detailed signal information.
- Valgrind's gdbserver now allows the user to change the signal
to deliver to the process. So, use 'signal SIGNAL' to continue execution
with SIGNAL instead of the signal reported to GDB. Use 'signal 0' to
continue without passing the signal to the process.
- With GDB >= 7.10, the command 'target remote'
will automatically load the executable file of the process running
under Valgrind. This means you do not need to specify the executable
file yourself, GDB will discover it itself. See GDB documentation about
'qXfer:exec-file:read' packet for more info.
* ==================== 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 (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.

Release 3.10.1 (25 November 2014)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.10.1 is a bug fix release. It fixes various bugs reported in 3.10.0
and backports fixes for all reported missing AArch64 ARMv8 instructions
and syscalls from the trunk. If you package or deliver 3.10.0 for others
to use, you might want to consider upgrading to 3.10.1 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 (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.
