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.

Slightly improve x86 unwind intensive workload.
e.g. perf/memrw is improved by 2% to 3% with this patch.
The unwinding code on x86 is trying to unwind using
either the %ebp-chain or CFI unwinding.
If these 2 techniques fail, then it tries to unwind
using FPO (PDB) debug info.
However, unless running wine or similar, there will never be
such FPO/PDB info.
The function VG_(use_FPO_info) is thus called for nothing
for each 'end of stack'. This function scans all the loaded di
to find a debug info that has some FP, to not find anything.
With this patch, the unwind code on x86 will only call VG_(use_FPO_info) if
some FPO/PDB info was loaded.
The fact that FPO/PDB info was loaded is cached and updated similarly to
cfi cache : each time new debug info is loaded, the cache value is refreshed
using the debuginfo generation.
The patch also changes the name of VG_(CF_info_generation)
to VG_(debuginfo_generation), as this generation is changed for
any kind of load or unload of debug info, not only for CFI based debug
info

Merge r14202 from the BUF_REMOVAL branch to trunk.
This patch changes the interface and behaviour of VG_(demangle) and
VG_(maybe_Z_demangle). Instead of copying the demangled name into a
fixed sized buffer that is passed in from the caller (HChar *buf, Int n_buf),
the demangling functions will now return a pointer to the full-length
demangled name (HChar **result). It is the caller's responsiblilty to
make a copy if needed.
This change in function parameters ripples upward
- first: to get_sym_name
- then to the convenience wrappers
- VG_(get_fnname)
- VG_(get_fnname_w_offset)
- VG_(get_fnname_if_entry)
- VG_(get_fnname_raw)
- VG_(get_fnname_no_cxx_demangle)
- VG_(get_datasym_and_offset)
The changes in foComplete then forces the arguments of
- VG_(get_objname) to be changed as well
There are some issues regarding the ownership and persistence of
character strings to consider.
In general, the returned character string is owned by "somebody else"
which means the caller must not free it. Also, the caller must not
modify the returned string as it possibly points to read only memory.
Additionally, the returned string is not necessarily persistent. Here are
the scenarios:
- the returned string is a demangled function name in which case the
memory holding the string will be freed when the demangler is called again.
- the returned string hangs off of a DebugInfo structure in which case
it will be freed when the DebugInfo is discarded
- the returned string hangs off of a segment in the address space manager
in which case it may be overwritten when the segment is merged with
another segment
So the rule of thunb here is: if in doubt strdup the string.

This commit is for Bugzilla 334384. The Bugzilla contains patch 1 of 3
to add PPC64 LE support. The other two patches can be found in Bugzillas
334834 and 334836. The commit does not have a VEX commit associated with it.
POWER PC, add initial Little Endian support
The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code. This patch adds the Little Endian #define ppc64le to the
Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.
The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific. The patch does not break the code for PPC64 Big Endian.
The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.

This patch implements the support needed for stacktraces
showing inlined function calls.
See 278972 valgrind stacktraces and suppression do not handle inlined function call debuginfo
Reading the inlined dwarf call info is activated using the new clo
--read-inline-info=yes
Default is currently no but an objective is to optimise the performance
and memory in order to possibly set it on by default.
(see below discussion about performances).
Basically, the patch provides the following pieces:
1. Implement a new dwarf3 reader that reads the inlined call info
2. Some performance improvements done for this new parser, and
on some common code between the new parser and the var info parser.
3. Use the parsed inlined info to produce stacktrace showing inlined calls
4. Use the parsed inlined info in the suppression matching and suppression generation
5. and of course, some reg tests
1. new dwarf3 reader:
---------------------
Two options were possible: add the reading of the inlined info
in the current var info dwarf reader, or add a 2nd reader.
The 2nd approach was preferred, for the following reasons:
The var info reader is slow, memory hungry and quite complex.
Having a separate parsing phase for the inlined information
is simpler/faster when just reading the inlined info.
Possibly, a single parser would be faster when using both
--read-var-info=yes and --read-inline-info=yes.
However, var-info being extremely memory/cpu hungry, it is unlikely
to be used often, and having a separate parsing for inlined info
does in any case make not much difference.
(--read-var-info=yes is also now less interesting thanks to commit
r13991, which provides a fast and low memory "reasonable" location
for an address).
The inlined info parser reads the dwarf info to make calls
to priv_storage.h ML_(addInlInfo).
2. performance optimisations
----------------------------
* the abbrev cache has been improved in revision r14035.
* The new parser skips the non interesting DIEs
(the var-info parser has no logic to skip uninteresting DIEs).
* Some other minor perf optimisation here and there.
In total now, on a big executable, 15 seconds CPU are needed to
create the inlined info (on my slow x86 pentium).
With regards to memory, the dinfo arena:
with inlined info: 172281856/121085952 max/curr mmap'd
without : 157892608/106721280 max/curr mmap'd,
So, basically, inlined information costs about 15Mb of memory for
my big executable (compared to first version of the patch, this is
already using less memory, thanks to the strpool deduppoolalloc.
The needed memory can probably be decreased somewhat more.
3. produce better stack traces
------------------------------
VG_(describe_IP) has a new argument InlIPCursor *iipc which allows
to describe inlined function calls by doing repetitive calls
to describe_IP. See pub_tool_debuginfo.h for a description.
4. suppression generation and matching
--------------------------------------
* suppression generation now also uses an InlIPCursor *iipc
to generate a line for each inlined fn call.
* suppression matching: to allow suppression matching to
match one IP to several function calls in a suppression entry,
the 'inputCompleter' object (that allows to lazily generate
function or object names for a stacktrace when matching
an error with a suppression) has been generalised a little bit
more to also lazily generate the input sequence.
VG_(generic_match) has been updated so as to be more generic
with respect to the input completer : when providing an
input completer, VG_(generic_match) does not need anymore
to produce/compute any input itself : this is all delegated
to the input completer.
5. various regtests
-------------------
to test stack traces with inlined calls, and suppressions
of (some of) these errors using inlined fn calls matching.
Work still to do:
-----------------
* improve parsing performance
* improve the memory overhead.
* handling the directory name for files of the inlined function calls is not yet done.
(probably implies to refactor some code)
* see if m_errormgr.c *offsets arrays cannot be managed via xarray

Improves stacktrace unwinding on x86
* other platforms (e.g. amd64) are first trying to unwind
with cfi info, then with the fp chain.
* fp unwind when code is compiled without frame pointer can
fail and give incomplete stack traces (often terminating
with a random program counter, causing a huge amount of
recorded stack traces).
This patch improves unwinding on x86 by:
* first time an IP is unwound, do the unwind both with
CFI technique and with fp technique.
If results are identical, IP is inserted in a cache of
'fp unwindable' IP
* following unwind of the same IP are then done directly
either with fp unwind or with cfi, depending on the
cached result of the check done during first unwind.
The cache is needed so as to avoid as much as possible cfi unwind,
as this is significantly slower than fp unwind.

Don't break fcntl locks when program does mmap. #280965.
(Rusty Russell, rusty@rustcorp.com.au)
tdb uses fcntl locks and mmap, and some of the tests fail under valgrind.
strace showed valgrind opening the tdb file, reading 1024 bytes, then closing
it. This is not allowed: POSIX says if you open and close a file, all fcntl
locks on it are dropped (insane, yes).
Finally got around to hacking the source to track this down: di_notify_mmap is
doing the damage. The simplest fix was to hand in an optional fd for it to
use, then have it do pread.
I had to fix your pread; surely this should seek back even if the platform
doesn't have pread support?

Add initial support for Mac OS X 10.7 (Lion). Tracked by bug #275168.
* configure.in support
* new supp file darwin11.supp
* comment out many intercepts in mc_replace_strmem.c and
vg_replace_malloc.c that are apparently unnecessary for Darwin
* add minimal handling for the following new syscalls and mach traps:
mach_port_set_context
task_get_exception_ports
getaudit_addr
psynch_mutexwait
psynch_mutexdrop
psynch_cvbroad
psynch_cvsignal
psynch_cvwait
psynch_rw_rdlock
psynch_rw_wrlock
psynch_rw_unlock
psynch_cvclrprepost
* wqthread_hijack on amd64-darwin: deal with
tst->os_state.pthread having an apparently different offset,
which caused an assertion failure
* m_debuginfo: for 32 bit processes on Lion, use the DebugInfoFSM
cleanup added in r12041/12042 to handle apparently new dyld
behaviour, which is to map text areas r-- first and only
vm_protect them later to r-x.
The following cleanups remain to be done
* remove apparently pointless, commented out wrapper macro
invokations in mc_replace_strmem.c, eg
//MEMMOVE(VG_Z_DYLD, memmove)
(or determine that they are still necessary, and uncomment)
* ditto in vg_replace_malloc.c, plus general VGO_darwin cleanups
there
* write proper syscall wrappers for
mach_port_set_context
task_get_exception_ports
getaudit_addr
psynch_mutexwait
psynch_mutexdrop
psynch_cvbroad
psynch_cvsignal
psynch_cvwait
psynch_rw_rdlock
psynch_rw_wrlock
psynch_rw_unlock
psynch_cvclrprepost
These are currently just no-ops and may be causing Memcheck to
report false undef-value errors
* figure out why it doesn't work properly unless built with gcc-4.2 on
Lion.
gcc-4.2 is the "normal" gcc (i686-apple-darwin11-gcc-4.2.1). Plain
gcc is the hybrid gcc-front-end clang-back-end thing
(i686-apple-darwin11-llvm-gcc-4.2). Whereas on Snow Leopard, plain
gcc is the normal gcc.
The symptoms of the failure are that wqthread_hijack in
syswrap-amd64-linux.c hits this /*NOTREACHED*/ vg_assert(0); right
at the end (you need a pretty complex threaded app to trigger this),
which makes me think that either ML_(wqthread_continue_NORETURN) or
call_on_new_stack_0_1 do return, which they are not expected to.
* figure out if some of the uninitialised value errors reported in
system libraries on are caused by Memcheck being confused by LLVM
generated code, as per bug #242137

Make the Dwarf3 CFI stack unwinding machinery work on arm-linux
too. This is a first step towards making not be completely
x86/amd64-linux specific, and so replaces some x86/amd64-specific
stuff with more general constructions:
* structure 'DiCfSI', into which the info is summarised, has been
made target-specific (ugh), since the sets of registers to be
unwound differ on different targets.
* enum CfiReg and the CFIC_ constants have been expanded
accordingly, to handle both arm and x86/amd64 registers.
The abbreviation "IA" (Intel Architecture) has been used in a
few places where the x86 and amd64 definitions are shared.
* the CFI reader/summariser in readdwarf.c has been expanded &
generalised appropriately.
* the DiCfSI evaluator in debuginfo.c, VG_(use_CFI_info), has
also been generalised appropriately.
The main change is that instead of passing around triples
of (IP, SP, BP) values, a new structure 'D3UnwindRegs' is
passed around instead. This is defined differently for IA and
ARM and succeeds in hiding at least some of the differences
where we don't care about them.
Note also, D3UnwindRegs duplicates, in purpose and structure,
structure 'RegSummary' in priv_d3basics.h. This will be tidied
up in due course.
This commit almost certainly breaks stack unwinding on amd64-linux.

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.

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.

Cleaned up the demangling mess:
- Now more clearly distinguishing between C++-demangling, Z-demangling, and
below-main renaming, particularly in 'get_sym_name'.
- --demangle=no no longer prevents Z-demangling, which makes more sense,
although it's unlikely to affect anyone.
- Broke the circular dependency between m_demangle and m_debuginfo by moving
below-main renaming into m_debuginfo.
- Renamed some get_fnname_* functions to make their effect clearer, and
improved their comments.

Fix an all-platforms bug introduced by the recent overhaul of function
interception and wrapping. This was causing failures matching
function names in suppressions to function names in backtraces when
the latter names were Z-encoded (eg malloc), which typically caused
all leak suppressions to fail because they contain names such as
malloc, which are Z-encoded.

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.

Made m_debuginfo not depend on m_aspacemgr, breaking the direct circular
dependence between them. (There's still an indirect one via m_libcmman.)
As a result, I was able to move the Segment type declaration into
pub_core_aspacemgr.h, which is a much better spot. I was also able to
