ed39800a83baf5bffbe391f3974eb2af0f415f80 21-Jun-2017 Elliott Hughes <enh@google.com> Upgrade to valgrind 3.13.0 (15 June 2017).

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"
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

where XXXXXX is the bug number as listed below.

* perf/vg_perf:
Similarly to tests/vg_regtest, perf/vg_perf now accepts the 3
optional arguments:
--outer-valgrind
--outer-tool
--outer-args

This allows easy analysis or comparison of performance between
different Valgrind versions (e.g. using callgrind, or cachegrind/cg_diff).

* See README_DEVELOPERS for more details.

* vg_regtest modified so as to use the 'in-place' build of inner, rather
than the installed version.

* added option --smc-check=all-non-file to vg_perf and vg_regtest
outer default arguments (needed when evaluating a Valgrind which does
translation chaining).

- show percentage speedup over the first Valgrind when comparing multiple

- don't accept --reps < 0
- avoid div-by-zero if the runtime is measured as zero

(use "make perf" to run) that executes test programs and times their
slowdowns under various tools. It works a lot like the vg_regtest script.
It's a bit rough around the edges -- eg. you can't currently directly
compare two different versions of Valgrind, which would be useful -- but it
is a good start.

There are currently two test programs in perf/. More will be added as time
goes on. This stuff will be built on so that performance changes can be
tracked over time.
