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.

Get rid of the remaining "set but not used" warnings reported by gcc 4.6 by
swapping the roles of the VALGRIND_DO_CLIENT_REQUEST() and
VALGRIND_DO_CLIENT_REQUEST_EXPR() macros. Also, many __attribute__((unused))
declarations on variables have been eliminated. Closes #269778.
Note: so far this patch has been tested on x86/Linux, amd64/Linux and
ppc64/Linux but not yet on any other supported CPU/OS combination.

This commit completely overhauls the leak checker. In particular:
- It heavily refactors the code: uses better names for things, splits up
complex functions that behaved very differently depending on how they were
called, removes some redundancies, and generally makes it much simpler and
easier to follow.
- It adds lots of comments, both inline, and also a big explanatory one at
the top which makes it clear exactly how the leak checker works and also
exactly what is meant by definite, possible, and indirect leaks. It also
has some ideas for future improvements.
- All tabs have been converted to spaces.
It also improves the functionality:
- Previously if you did --leak-check=summary, indirect and suppressed
blocks were counted as definite leaks. Now they are done properly, and so
the summary results from --leak-check=summary match those from
--leak-check=yes.
- Previously, some possibly reachable blocks were miscategorised as
definitely reachable, because only the pointer to the block itself was
considered, not any preceding pointers in the chain. This is now fixed.
- Added memcheck/tests/leak-cases, which fully tests all the possible
combinations of directly/indirectly reachable and possibly/definitely
reachable.
And it improves the manual quite a bit, and the FAQ a little bit.
This doesn't fix the leak checker to handle MALLOCLIKE_BLOCK works that have
been taken from within malloc'd blocks, but I think I know how to do it and
hope to do so in a subsequent commit.
It also changes all instances of "<constant>memcheck</constant>" in the
Memcheck manual to "Memcheck", for consistency and because "Memcheck" is
easier to write. There's one similar case for DRD but I didn't change that.

Terminology change: previously in Memcheck we had the four states:
noaccess, writable, readable, other
Now they are:
noaccess, undefined, defined, partdefined
As a result, the following names:
make_writable, make_readable,
check_writable, check_readable, check_defined
have become:
make_mem_undefined, make_mem_defined,
check_mem_is_addressable, check_mem_is_defined, check_value_is_defined
(and likewise for the upper-case versions for client request macros).
The old MAKE_* and CHECK_* macros still work for backwards compatibility.
This is much better, because the old names were subtly misleading. For
example:
- "readable" really meant "readable and writable".
- "writable" really meant "writable and maybe readable, depending on how
the read value is used".
- "check_writable" really meant "check writable or readable"
The new names avoid these problems.
The recently-added macro which was called MAKE_DEFINED is now
MAKE_MEM_DEFINED_IF_ADDRESSABLE.
I also corrected the spelling of "addressable" in numerous places in
memcheck.h.

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)).

Add a new kind of memory-painting primitive, which is: 'make_defined'.
For each byte in the range, if the byte is addressible, make it be
initialised, but if it isn't addressible, leave it alone. So it's
like a version of make_readable which doesn't alter addressibility.

This jumbo-checkin is the Full Virtualization checkin. This eliminates
Valgrind's dependency on the dynamic linker for getting started, and
instead takes things into its own hands.
This checkin doesn't add much in the way of new functionality, but it
is the basis for all future work on Valgrind. It allows us much more
flexibility in implementation, and well as increasing the reliability
of Valgrind by protecting it more from its clients.
This patch requires some changes to tools to update them to the changes
in the tool API, but they are straightforward. See the posting "Heads
up: Full Virtualization" on valgrind-developers for a more complete
description of this change and its effects on you.

Started to rescind the name "skin", replacing it with "tool". Did this in all
the places that normal users will see:
- command line: --tool=foo (although --skin=foo still works)
- docs: removed all traces (included renaming coregrind_skins.html to
coregrind_tools.html)
- in the usage messages
- in error messages
Also did in in some places that I judged were unlikely to cause clashes with
existing workspaces:
- in the header comments of many files (eg. "This file is part of Memcheck, a
Valgrind tool for...")
- in the regtests script
- in the .supp files
- in AUTHORS
- in README_MISSING_SYSCALL_OR_IOCTL
Also update the AUTHORS file to mention Jeremy.

Moved the MALLOCLIKE and FREELIKE client requests out of memcheck.h, and into
valgrind.h. Although these requests are not implemented by the core, they can
be implemented by skins that track heap blocks, eg. Memcheck, Annelid, Massif.
This is in preparation for committing Massif to the repository.
I think I managed to make the change in a binary-compatible way. The only
inconvenience for users is that if they have a client program compiled with the
old requests in, Valgrind will abort with an explanatory message that tells
them to recompile. Once they've done that (no changes to their program are
required), it works again.
I even updated the docs.

Fixed up the client request info in the docs, which required splitting the core
requests from the Memcheck requests and putting the descriptions in the
appropriate parts of the docs.
Removed the __VALGRIND_SOME_SKIN_H test -- it was designed to prevent people
#including valgrind.h when they probably want memcheck.h, but it's actually a
reasonable thing to do to #include valgrind.h alone, because there are some
requests in valgrind.h.
Removed references to VALGRIND_MAKE_NOACCESS_STACK from the docs, as it doesn't
exist in the implementation.
Fixed a few other minor things.

Added VALGRIND_MALLOCLIKE_BLOCK and VALGRIND_FREELIKE_BLOCK which allow you to
use a custom-allocator and detect almost as many errors as you could detect if
you used malloc/new/new[]. (eg. leaks detected, free errors, free mismatch,
etc).
Had to fiddle with mac_malloc_wrappers.c a bit to factor out the appropriate
code to be called from the client request handling code. Also had to add a
new element `MAC_AllocCustom' to the MAC_AllocKind type.
Also added a little documentation, and a regression test.

Added two client requests: VALGRIND_COUNT_ERRORS and VALGRIND_COUNT_LEAKS.
The first returns the number of errors found so far, and is a core request.
The second returns the number of bytes found
reachable/dubious/leaked/suppressed by all leak checks so far, for Memcheck and
Addrcheck.
Both are useful for using Valgrind in regression test suites where multiple
tests are present in a single file -- one can run Valgrind with no output
(using --logfile-fd=-1) and use the requests after each test to determine if
any errors happened.
Had to rename and make public vg_n_errs_found --> VG_(n_errs_found) to do so.
Nb: leak errors are not counted as errors for the purposes of
VALGRIND_COUNT_ERRORS. This was decided as the best thing to do after
discussion with Olly Betts, who original suggested these changes.
Pulled out common client request code shared between Memcheck and Addrcheck.
Added a regression test for this.
Added some documentation too.

Various fixes to the client-perms include files to stop gccs yelping
at high warning levels. Partially due to Andreas Jaeger and
Hans-Peter Nilsson.
MERGE TO STABLE.

A little cpp magic to cause compilation to fail if valgrind.h is included
directly into sources (it should not be, and was causing people problems).

Remove the mechanism which allowed clients to set block permissions
on their stacks and have those blocks automatically cleared when the
stack retreats past them. This never really worked, certainly didn't
work in a multithreaded setting, and slowed everything down due to
having to do even more stuff at %esp changes.

Merge patch from Jeremy Fitzhardinge:
08-skin-clientreq
Introduce a systematic way for skins to distinguish each other's
client requests. Uses the de-facto standard two-letter identifiers in
the top two bytes of the client request code. Also changes the
interface to SK_(handle_client_request) so that a skin can say whether
or not it handled the request, which allows correct setting of the
default return value if the request was not handled.

Updated file descriptions in the copyright notices to reflect the core/skin
split. Each skin now has its own two-line description.
