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 revisions 14255, 14293, and 14294 from the BUF_REMOVAL branch to trunk.
The functions VG_(get_filename) and VG_(get_filename_lineno) now return
a pointer to filename and directory name instead of copying them into
buffers passed in from the caller.
The returned strings are persistent as long as the DebugInfo to which
they belong is not discarded. The caller therefore needs to stash them
away as needed.
Function VG_(strncpy_safely) has been removed as it is no longer needed.

Remove a comment that is no longer valid. The real reason we (now)
don't provide strtoll etc is that we don't need the flexibility and
are too lazy to implement the general case :) But that does not
warrant a comment in the code.

The attached patch cleanups the clo processing
of clo which are (or should be) 'enum set'.
* pub_tool_options.h : add new macrox VG_USET_CLO and VG_USETX_CLO to
parse an 'enum set' command line option (with or without "all" keyword).
* use VG_USET_CLO for existing enum set clo options:
memcheck --errors-for-leak-kinds, --show-leak-kinds, --leak-check-heuristics
coregrind --vgdb-stop-at
* change --sim-hints and --kernel-variants to enum set
(this allows to detect user typos: currently, a typo in a sim-hint
or kernel variant is silently ignored. Now, an error will be given
to the user)
* The 2 new sets (--sim-hints and --kernel-variants) should not make
use of the 'all' keyword => VG_(parse_enum_set) has a new argument
to enable/disable the use of the "all" keyword.
* The macros defining an 'all enum' set definition was duplicating
all enum values (so addition of a new enum value could easily
give a bug). Removing these macros as they are unused
(to the exception of the leak-kind set).
For this set, the 'all macro' has been replaced by an 'all function',
coded using parse_enum_set parsing the "all" keyword.

Merge the DARWIN branch onto the trunk.
I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts. So instead I just took the diff between
the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

atoll() is a terrible function -- you can't do any error checking with it.
Some of our option processing code uses it. This means that eg.
'--log-fd=9xxx' logs to fd 9, and '--log-fd=blahblahblah' logs to 0 (because
atoll() returns 0 if the string doesn't contain a number!)
It turns out that most of our option processing uses VG_(strtoll*) instead
of VG_(atoll). The reason that not all of it does is that the
option-processing macros are underpowered -- they currently work well if you
just want to assign the value to a variable, eg:
VG_BOOL_CLO(arg, "--heap", clo_heap)
else VG_BOOL_CLO(arg, "--stacks", clo_stacks)
else VG_NUM_CLO(arg, "--heap-admin", clo_heap_admin)
else VG_NUM_CLO(arg, "--depth", clo_depth)
(This works because they are actually an if-statement, but it looks odd.)
VG_NUM_CLO uses VG_(stroll10). But if you want to do any checking or
processing, you can't use those macros, leading to code like this:
else if (VG_CLO_STREQN(9, arg, "--log-fd=")) {
log_to = VgLogTo_Fd;
VG_(clo_log_name) = NULL;
tmp_log_fd = (Int)VG_(atoll)(&arg[9]);
}
So this commit:
- Improves the *_CLO_* macros so that they can be used in all circumstances.
They're now just expressions (albeit ones with side-effects, setting the
named variable appropriately). Thus they can be used as if-conditions,
and any post-checking or processing can occur in the then-statement. And
malformed numeric arguments (eg. --log-fd=foo) aren't accepted. This also
means you don't have to specify the lengths of any option strings anywhere
(eg. the 9 in the --log-fd example above). The use of a wrong number
caused at least one bug, in Massif.
- Updates all places where the macros were used.
- Updates Helgrind to use the *_CLO_* macros (it didn't use them).
- Updates Callgrind to use the *_CLO_* macros (it didn't use them), except
for the more esoteric option names (those with numbers in the option
name). This allowed getUInt() and getUWord() to be removed.
- Improves the cache option parsing in Cachegrind and Callgrind -- now uses
VG_(strtoll10)(), detects overflow, and is shorter.
- Uses INT instead of NUM in the macro names, to distinguish better vs. the
DBL macro.
- Removes VG_(atoll*) and the few remaining uses -- they're wretched
functions and VG_(strtoll*) should be used instead.
- Adds the VG_STREQN macro.
- Changes VG_BINT_CLO and VG_BHEX_CLO to abort if the given value is outside

- Add 'unit_libcbase', the beginnings of a unit test module for m_libcbase.
- Rename 'oset_test' as 'unit_oset' to make its meaning more clear.
- Remove VG_(atoll36), VG_(strtoll8)() and VG_(strtoll36)(); they're not
used and so untested, but easy to crib from similar functions if they need
to be added again later.

Add a new module, m_seqmatch, which does very simple sequence (regexp)
matching, in the function VG_(generic_match). Patterns to be matched
against may contain only '*'-style wildcards (matches any number of
elements, we don't care what they are), '?' wildcards (matches exactly
one element, we don't care what it is) and literal elements.
It is totally abstractified, in the sense that the pattern and input
arrays may be arrays of anything. The caller provides enough
information so that VG_(generic_match) can step along both arrays, and
can ask the questions "is this pattern element a '*' ?", "is this
pattern element a '?' ?", and "does this pattern element match an
input element ?".
The existing function VG_(string_match) is reimplemented using
VG_(generic_match), although the ability to escape metacharacters in
the pattern string is removed -- I don't think it was ever used.
In m_errormgr, matching of suppression stacks (including wildcard
"..." lines) against error stacks is re-implemented using
VG_(generic_match).
Further detailed comments are in m_seqmatch.h and pub_tool_seqmatch.h.
A negative side effect is that VG_(string_match) will be much slower
than before, due to the abstractification. It may be necessary to
reimplement a specialised version later.

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.

Add four 'strtoll' variants, which are like 'atoll' but let you detect if
the string converted wasn't entirely numeric. Using them for numeric
command-line options -- previously if you had a option "--foo=<n>", where
<n> is supposed to be an integer, then "--foo=blah" would be interpreted as
"--foo=0", because the "blah" would be converted to zero and the remaining
chars wouldn't be noticed.
Fixed an incorrect command-line option in two massif tests that this change
exposed.

Merge in the COMPVBITS branch to the trunk. This is a big change to
Memcheck, replacing the 9-bits-per-byte shadow memory representation to a
2-bits-per-byte representation (with possibly a little more on the side) by
taking advantage of the fact that extremely few memory bytes are partially
defined.
For the SPEC2k benchmarks with "test" inputs, this speeds up Memcheck by a
(geometric mean) factor of 1.20, and reduces the size of shadow memory by a
(geometric mean) factor of 4.26.
At the same time, Addrcheck is removed. It hadn't worked for quite some
time, and with these improvements in Memcheck its raisons-d'etre have
shrivelled so much that it's not worth the effort to keep around. Hooray!
Nb: this code hasn't been tested on PPC. If things go wrong, look first in
the fast stack-handling functions (eg. mc_new_mem_stack_160,
MC_(helperc_MAKE_STACK_UNINIT)).

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.

Started modularising vg_mylibc. Put all the standalone stuff -- ie. not
relying on any other modules -- in m_libcbase.
Also converted the 'size' parameters to functions like VG_(memcpy) and
VG_(strncpy) from Int to SizeT, as they should be.
Also removed VG_(atoll16) and VG_(toupper), which weren't being used.
Also made VG_(atoll36) less flexible -- it now only does base-36 numbers
instead of any base in the range 2..36, since base-36 is the only one we
need. As part of that, I fixed a horrible bug in it which caused it to
return incorrect answers for any number containing the digits 'A'..'I'!
(Eg. for "A; it would return 17 instead of 10!)
Had to disable the assertions in VG_(string_match), since this module can't
see vg_assert, which wasn't ideal but also isn't a disaster.
