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.

Change VG_(mkstemp) such that
(a) the 2nd argument must not be NULL
This was true anyhow and requiring it allows us to simplify the function
by eliminating the local buffer.
(b) the memory pointed to by the 2nd argument is always initialised
In the past the output file name was not initialised in case VG_(open)
failed 10 times in a row. The call sites in m_main.c and m_gdbserver/target.c
were reading the uninitialised filename unconditionally. This was spotted
by IBM's BEAM checker.
Fix call sites, eliminate some magic constants along the way.

Change VG_(allocEltDedupPA) to return a pointer to const. The reason is
that once an element has been allocated and added to the pool it must
not be modified afterwards. See the documentation in pub_tool_deduppoolalloc.h

Reduce memory needed for symbols, by having the tocptr and local_ep
(used for ppc64 platforms) #ifdef-ed and accessed by macros
that becomes NOP on non ppc64 platforms.
This decreases the debuginfo memory by about 2.5 Mb on a big 32 bit application.
Note : doing that, some questions were encountered in the way
tocptr and local_ep have (or do not have) to be copied/maintained
in storage.c canonicaliseSymtab

optimise readpdb.c filename and dirname handling, following r14158
r14158 introduced a dedup pool to store pairs (filename,dirname).
The windows debug info reader (readpdb.c) performance was still to be
improved, as calls to ML_(addFnDn) were done for each line loc to add.
With this patch, the nr of calls to ML_(addFnDn) should be reduced
significantly.
Code has been compiled and regtested on linux, but no windows/wine test
was done.

This patch decreases significantly the memory needed to store the lineloc info.
On a big executable, the trunk needs:
dinfo: 134873088/71438336 max/curr mmap'd, 134607808/66717872 max/curr
With the patch, we have:
dinfo: 99065856/56836096 max/curr mmap'd, 97883776/51663656 max/curr
So, peak dinfo memory decreases by about 36Mb, and final by 15Mb.
(for info, valgrind 3.9.0 uses
dinfo: 158941184/109666304 max/curr mmap'd, 156775944/107590656 max/curr
So, compared to 3.9.0, dinfo peak decreases by about 40%, and the final
memory is divided by more than 2).
The memory decrease is obtained by:
* using a dedup pool to store filename/dirname pair for the loctab source/line
information.
As typically, there is not a lot of such pairs, typically a UShort is
good enough to identify a fn/dn pair in a dedup pool.
To avoid losing memory due to alignment, the fndn indexes are stored
in a "parallel" array to the DiLoc loctab array, with entries having
1, or 2 or 4 bytes according to the nr of fn/dn pairs in the dedup pool.
See priv_storage.h comments for details.
(there was a extensible WordArray local implementation in readdwarf.c.
As with this change, we use an xarray, the local implementation was
removed).
* the memory needed for --read-inline-info is slightly decreased (-2Mb)
by removing the (unused) dirname from the DiInlLoc struct.
Handling dirname for inlined function caller implies to rework
the dwarf3 parser read_filename_table common to the var and inlinfo parser.
Waiting for this to be done, the dirname component is removed from DiInlLoc.
* the stabs reader (readstabs.c) is broken since 3.9.0.
For this change, the code has been updated to make it compile with the new
DiLoc/FnDn dedup pool. As the code is completely broken, a vg_assert(0)
has been put at the begin of the stabs reader.
* the pdb reader (readpdb.c) has been trivially updated and should still work.
It has not been tested (how do we test this ?).
A follow-up patch will be done to avoid doing too many calls to
ML_(addFnDn) : instead of having one call per ML_(addLineInfo), one
should have a single call done when reading the filename table.
This has also be tested in an outer/inner setup, to verify no
memory leak/bugs.

so the auto-update script will handle them correctly in future.

A refactoring change; no functional effect. struct _DebugInfo
contains a bunch of fields which are used as a very simple state
machine that observes mmap calls and decides when to read debuginfo
for the associated file. This change moves these fields into their
own structure, struct _DebugInfoFSM, for cleanness, so as to make it
clear they have a common purpose.

Remove the assumption, in m_debuginfo, that each address is associated
with only one symbol. Instead, allow an address to have arbitrarily
many names. This reflects reality better, particularly for systemy
libraries such as glibc and ld.so, and is background work needed for
fixing #275284. This is not in itself a fix for #275284. A followup
commit to un-break compilation on OSX will follow shortly.

Try to find the PDB file for a given PE file by the totally kludgey
method of doing "strings file.dll | egrep '\.pdb|\.PDB'".
Distantly derived from a patch by leiz@ucla.edu. Fixes #222902,
although I still would prefer to do this the proper way, by parsing
the PE file properly.

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.

When looking for the text section in a PE executable ignore any
code section which is marked as uninitialised.
This can happen if you have incremental linking enabled in Visual
Studio, which causes a .textbss section to be added before the real
text section. We were picking up that .textbss section and using it to
compute the avma and bias for the code which was giving completely the
wrong results.

This commit merges the BUILD_TWEAKS branch onto the trunk. It has the
following improvements:
- Arch/OS/platform-specific files are now included/excluded via the
preprocessor, rather than via the build system. This is more consistent
(we use the pre-processor for small arch/OS/platform-specific chunks
within files) and makes the build system much simpler, as the sources for
all programs are the same on all platforms.
- Vast amounts of cut+paste Makefile.am code has been factored out. If a
new platform is implemented, you need to add 11 extra Makefile.am lines.
Previously it was over 100 lines.
- Vex has been autotoolised. Dependency checking now works in Vex (no more
incomplete builds). Parallel builds now also work. --with-vex no longer
works; it's little use and a pain to support. VEX/Makefile is still in
the Vex repository and gets overwritten at configure-time; it should
probably be renamed Makefile-gcc to avoid possible problems, such as
accidentally committing a generated Makefile. There's a bunch of hacky
copying to deal with the fact that autotools don't handle same-named files
in different directories. Julian plans to rename the files to avoid this
problem.
- Various small Makefile.am things have been made more standard automake
style, eg. the use of pkginclude/pkglib prefixes instead of rolling our
own.
- The existing five top-level Makefile.am include files have been
consolidated into three.
- Most Makefile.am files now are structured more clearly, with comment
headers separating sections, declarations relating to the same things next
to each other, better spacing and layout, etc.
- Removed the unused exp-ptrcheck/tests/x86 directory.
- Renamed some XML files.
- Factored out some duplicated dSYM handling code.
- Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting
Makefile.am files to be much more standard.
- Cleaned up m_coredump by merging a bunch of files that had been
overzealously separated.
The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude
the added Makefile.vex.am, or 997 once the hacky file copying for Vex is
removed. And the build system is much simpler.

Add support for reading Windows PDB debug info (symbols and line
numbers) when Valgrind is running Wine. Modified version of a
patch by John Reiser (vgsvn+wine-load-pdb-debuginfo.patch) with
extensions to read a second format of line number tables.
Wine uses a new client request, VG_USERREQ__LOAD_PDB_DEBUGINFO,
to tell Valgrind when to read PDB info. Wine's implementation
of module loading is vastly different from that used by
ld-linux.so, and it is too difficult to recognize what is going
on just by observing the calls to mmap and mprotect.
