ed39800a83baf5bffbe391f3974eb2af0f415f80 21-Jun-2017 Elliott Hughes <enh@google.com> 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.

to add PPC64 LE support. The other two patches can be found in Bugzillas

POWER PC, add the functional Little Endian support, patch 2

The IBM POWER processor now supports both Big Endian and Little Endian.
The ABI for Little Endian also changes. Specifically, the function
descriptor is not used, the stack size changed, accessing the TOC
changed. Functions now have a local and a global entry point. Register
r2 contains the TOC for local calls and register r12 contains the TOC
for global calls. This patch makes the functional changes to the
Valgrind tool. The patch makes the changes needed for the
none/tests/ppc32 and none/tests/ppc64 Makefile.am. A number of the
ppc specific tests have Endian dependencies that are not fixed in
this patch. They are fixed in the next patch.

Per Julian's comments renamed coregrind/m_dispatch/dispatch-ppc64-linux.S
to coregrind/m_dispatch/dispatch-ppc64be-linux.S Created new file for LE
coregrind/m_dispatch/dispatch-ppc64le-linux.S. The same was done for
coregrind/m_syswrap/syscall-ppc-linux.S.

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.

When doing experiment with gcc 4.7.0 and link time optimisation,
encountered link failures on amd64 which were solved by adding
.globl and used attribute.
=> added .globl in similar places for arm/x86/ppc32/s390.
Did not touch darwin (which asm seems somewhat different).

- Introduced VG_SYSNUM_STRING and VG_SYSNUM_STRING_EXTRA which factor out
differences in the way syscall numbers are printed on different platforms.
This gets rid of seven "DDD" fixme-style comments.

- This also meant that Darwin syscall numbers are now printed in a
non-ambiguous way -- previously Unix, machine-dependent and diagnostic
syscalls were all printed the same way, even though their numbers overlap.
Now each number is prefixed with "unix", "mdep", etc. And Mach trap
numbers aren't printed as negative numbers now that they have a "mach"
prefix.

- Split each of pub_core_vkiscnums.h and pub_tool_vkiscnums.h into two
parts, one suitable for inclusion in asm files, one suitable for inclusion
in C files; in both cases the latter includes the former. This makes
this module more like other modules that have asm-only components (eg.
m_transtab); it also allows the hacky VG_IN_ASSEMBLY_SOURCE macros and
tests to be removed.

- Removed some of the VG_DARWIN_SYSNO_* macros that were no longer needed,
and renamed some of the existing ones to make their meanings clearer.

- Added comments on the encoding of Darwin syscall numbers so it's
possible for mortals to understand without reading the kernel code..

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.

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.

them.

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.

- Broke part of m_scheduler off into a new module m_threadstate. It
contains ThreadState, VG_(threads)[] and some basic operations on the
thread table. All simple stuff, the complex stuff stays in m_scheduler.
This avoids lots of circular dependencies between m_scheduler and other
modules.

- Managed to finally remove core.h and tool.h, double hurrah!

- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
include by every single C file.

- Lots of little cleanups and changes related to the above.

- I even did a small amount of documentation updating.

as it is not used anywhere else.

m_syscall.c. Plus some associated cleanups.

Moved VG_(sigreturn) into m_signals.c and made it local.
