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.

Upgrade to valgrind 3.12.0.
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.

Merge r14208 from BUF_REMOVAL branch to trunk.
In function read_dot_valgrindrc use a large enough buffer
allocated on the stack.
Also assert that the passed in directory is not NULL. This is
true at all call sites. The old code would have attempted to read
/.valgrindrc for dir == NULL and I don't think we want that.

Merge 14206,14207,14261,14577,14578 from BUF_REMOVAL branch to trunk.
This changes VG_(record_startup_wd) to dynamically allocate a large
enough buffer for the directory name. As the dynamic memory manager has
started up a while ago, this is quite safe. Also rewrite VG_(get_startup_wd)
to simply return the directory name. No more messing with copying it
around. Adapt call sites.

Merge coregrind/ changes from branches/MESSAGING_TIDYUP r10464.
This commit tidies up and rationalises what could be called the
"messaging" system -- that part of V to do with presenting output to
the user. In particular it brings significant improvements to XML
output.
Changes are:
* XML and normal text output now have separate file descriptors,
which solves longstanding problems for XML consumers caused by
the XML output getting polluted by unexpected non-XML output.
* This also means that we no longer have to hardwire all manner
of output settings (verbosity, etc) when XML is requested.
* The XML output format has been revised, cleaned up, and made
more suitable for use by error detecting tools in general
(various Memcheck-specific features have been removed). XML
output is enabled for Ptrcheck and Helgrind, and Memcheck is
updated to the new format.
* One side effect is that the behaviour of VG_(message) has been
made to be consistent with printf: it no longer automatically
adds a newline at the end of the output. This means multiple
calls to it can be used to build up a single line message; or a
single call can write a multi-line message. The ==pid==
preamble is automatically inserted at each newline.
* VG_(message)(Vg_UserMsg, ..args..) now has the abbreviated form
VG_(UMSG)(..args..); ditto VG_(DMSG) for Vg_DebugMsg and
VG_(EMSG) for Vg_DebugExtraMsg. A couple of other useful
printf derivatives have been added to pub_tool_libcprint.h,
most particularly VG_(vcbprintf).
* There's a small change in the core-tool interface to do with
error handling: VG_(needs_tool_errors) has a new method
void (*before_pp_Error)(Error* err) which, if non-NULL, is
called just before void (*pp_Error)(Error* err). This is to
give tools the chance to look at errors before any part of them
is printed, so they can print any XML preamble they like.
* coregrind/m_errormgr.c has been overhauled and cleaned up, and
is a bit simpler and more commented. In particular pp_Error
and VG_(maybe_record_error) are significantly changed.
The diff is huge, but mostly very boring. Most of the changes
are of the form
- VG_(message)(Vg_UserMsg, "this is a message %d", n);
+ VG_(message)(Vg_UserMsg, "this is a message %d\n", n);
Unfortunately as a result of this, it touches a large number
of source files.

Merge all remaining changes from branches/PTRCHECK. These are some
relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.
The majority of the merged changes were committed into
branches/PTRCHECK as the following revs: 8591 8595 8598 8599 8601 and
8161.

Presently, Valgrind (non-client) code that wants to use the stat
family of syscalls is impossible to write in a way that's portable and
correct. On some targets (eg x86-linux) you need to do sys_stat64 and
receive the results in a 'struct vki_stat64'. But on other targets
(eg amd64-linux) neither sys_stat64 nor 'struct vki_stat64' exist.
This commit adds a new type, 'struct vg_stat', which contains 64 bit
fields in all the right places, and makes VG_(stat) and VG_(fstat) use
it. This means callers to the two functions no longer need to worry
about the is-it-64-bit-clean-or-not question, since these routines
reformat the received data into a'struct vg_stat'. Kind of like what
glibc must have been doing for decades.
This (indirectly) fixes a bug on x86-linux, in which m_debuginfo would
sometimes fail to read debug info, due to VG_(di_notify_mmap) using
VG_(stat) (hence sys_stat) on the file, which failed, and when in fact
it should have used sys_stat64. Bug reported and tracked down by
Marc-Oliver Straub.

Get rid of VG_(getcwd) and replace it with a pair of functions,
VG_(record_startup_wd) which records the working directory at startup,
and VG_(get_startup_wd) which later tells you what value was recorded.
This works because all uses of VG_(getcwd) serve only to record the
directory at process start anyway. The motivation is that AIX does
not support sys_getcwd directly, so it's easier for the launcher to
ship in the required value using an environment variable. On Linux
sys_getcwd is used as before.

Create a new module, m_vki, and move all knowledge about the kernel
interface, except for the syscall numbers, into that. Mostly this
means moving include/vki-*.h to include/vki/vki-*.h.
include/pub_tool_basics.h previously dragged in the entire kernel
interface. I've done away with that, so that modules which need to
see the kernel interface now have to include pub_{core,tool}_vki.h
explicitly. This is why there are many modified .c files -- they have
all acquired an extra #include line.
This certainly breaks all platforms except x86. Will fix shortly.

This commit merges in changes from branches/ASPACEM (specifically,
changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.
