Branch: CURRENT, Version: 3.17.0nb1, Package name: valgrind-3.17.0nb1, Maintainer: pkgsrc-users

Valgrind is an instrumentation framework for building dynamic analysis
tools. There are Valgrind tools that can automatically detect many memory
management and threading bugs, and profile your programs in detail. You
can also use Valgrind to build new tools.

The Valgrind distribution currently includes six production-quality
tools: a memory error detector, two thread error detectors, a cache
and branch-prediction profiler, a call-graph generating cache and
branch-prediction profiler, and a heap profiler. It also includes three
experimental tools: a heap/stack/global array overrun detector, a second
heap profiler that examines how heap blocks are used, and a SimPoint basic
block vector generator.

valgrind: update to 3.17.0

Release 3.17.0 (19 Mar 2021)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.17.0 fixes a number of bugs and adds some functional changes: support for
GCC 11, Clang 11, DWARF5 debuginfo, the 'debuginfod' debuginfo server, and
some new instructions for Arm64, S390 and POWER.  There are also some tool
updates.

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.  There is also preliminary
support for X86/macOS 10.13, AMD64/macOS 10.13 and nanoMIPS/Linux.

* ==================== CORE CHANGES ===================

* DWARF version 5 support.  Valgrind can now read DWARF version 5 debuginfo as
  produced by GCC 11.

* Valgrind now supports debuginfod, an HTTP server for distributing ELF/DWARF
  debugging information. When a debuginfo file cannot be found locally,
  Valgrind is able to query debuginfod servers for the file using its
  build-id. See the user manual for more information about debuginfod support.

* ================== PLATFORM CHANGES =================

* arm64:

  - Inaccuracies resulting from double-rounding in the simulation of
    floating-point multiply-add/subtract instructions have been fixed.  These
    should now behave exactly as the hardware does.

  - Partial support for the ARM v8.2 instruction set.  v8.2 support work is
    ongoing.  Support for the half-word variants of at least the following
    instructions has been added:
       FABS <Hd>, <Hn>
       FABS <Vd>.<T>, <Vn>.<T>
       FNEG <Hd>, <Hn>
       FNEG <Vd>.<T>, <Vn>.<T>
       FSQRT <Hd>, <Hn>
       FSQRT <Vd>.<T>, <Vn>.<T>
       FADDP

* s390:

  - Implement the new instructions/features that were added to z/Architecture
    with the vector-enhancements facility 1.  Also cover the instructions from
    the vector-packed-decimal facility that are defined outside the chapter
    "Vector Decimal Instructions", but not the ones from that chapter \ 
itself.

    For a detailed list of newly supported instructions see the updates to
    `docs/internals/s390-opcodes.csv'.

    Since the miscellaneous instruction extensions facility 2 was already
    added in Valgrind 3.16.0, this completes the support necessary to run
    general programs built with `--march=z14' under Valgrind.  The
    vector-packed-decimal facility is currently not exploited by the standard
    toolchain and libraries.

* ppc64:

  - Various bug fixes.  Fix for the sync field to limit setting just two of
    the two bits in the L-field. Fix the write size for the stxsibx and
    stxsihx instructions.  Fix the modsw and modsd instructions.

  - Partial support for ISA 3.1 has been added.  Support for the VSX PCV mask
    instructions, bfloat16 GER instructions, and bfloat16 to/from float 32-bit
    conversion instructions are still missing.

* ==================== TOOL CHANGES ====================

* General tool changes

  - All the tools and their vgpreload libraries are now installed under
    libexec because they cannot be executed directly and should be run through
    the valgrind executable. This should be an internal, not user visible,
    change, but might impact valgrind packagers.

  - The --track-fds option now respects -q, --quiet and won't output anything
    if no file descriptors are leaked. It also won't report the standard stdin
    (0), stdout (1) or stderr (2) descriptors as being leaked with
    --trace-fds=yes anymore. To track whether the standard file descriptors
    are still open at the end of the program run use --trace-fds=all.

* DHAT:

  - DHAT has been extended, with two new modes of operation. The new
    --mode=copy flag triggers copy profiling, which records calls to memcpy,
    strcpy, and similar functions. The new --mode=ad-hoc flag triggers ad hoc
    profiling, which records calls to the DHAT_AD_HOC_EVENT client request in
    the new dhat/dhat.h file. This is useful for learning more about hot code
    paths. See the user manual for more information about the new modes.

  - Because of these changes, DHAT's file format has changed. DHAT output
    files produced with earlier versions of DHAT will not work with this
    version of DHAT's viewer, and DHAT output files produced with this version
    of DHAT will not work with earlier versions of DHAT's viewer.

* ==================== 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.

valgrind: update to 3.16.1

Release 3.16.1 (22 June 2020)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.16.1 fixes two critical bugs discovered after 3.16.0 was frozen.  It also
fixes character encoding problems in the documentation HTML.

Release 3.16.0 (27 May 2020)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.16.0 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.  There is also preliminary
support for X86/macOS 10.13, AMD64/macOS 10.13 and nanoMIPS/Linux.

* ==================== CORE CHANGES ===================

* It is now possible to dynamically change the value of many command line
  options while your program (or its children) are running under Valgrind.

  To see the list of dynamically changeable options, run
     "valgrind --help-dyn-options".

  You can change the options from the shell by using vgdb to launch
  the monitor command "v.clo <clo option>...".
  The same monitor command can be used from a gdb connected
  to the valgrind gdbserver.
  Your program can also change the dynamically changeable options using
  the client request VALGRIND_CLO_CHANGE(option).

* ================== PLATFORM CHANGES =================

* MIPS: preliminary support for nanoMIPS instruction set has been added.

* ==================== TOOL CHANGES ====================

* DHAT:

  - The implicit memcpy done by each call to realloc now counts towards the
    read and write counts of resized heap blocks, making those counts higher
    and more accurate.

* Cachegrind:

  - cg_annotate's --auto and --show-percs options now default to 'yes', because
    they are usually wanted.

* Callgrind:

  - callgrind_annotate's --auto and --show-percs options now default to 'yes',
    because they are usually wanted.

  - The command option --collect-systime has been enhanced to specify
    the unit used to record the elapsed time spent during system calls.
    The command option now accepts the values no|yes|msec|usec|nsec,
    where yes is a synonym of msec.  When giving the value nsec, the
    system cpu time of system calls is also recorded.

* Memcheck:

  - Several memcheck options are now dynamically changeable.
    Use  valgrind --help-dyn-options  to list them.

  - The release 3.15 introduced a backward incompatible change for
    some suppression entries related to preadv and pwritev syscalls.
    When reading a suppression entry using the unsupported 3.14 format,
    valgrind will now produce a warning to say the suppression entry will not
    work, and suggest the needed change.

  - Significantly fewer false positive errors on optimised code generated by
    Clang and GCC.  In particular, Memcheck now deals better with the
    situation where the compiler will transform C-level "A && \ 
B" into "B && A"
    under certain circumstances (in which the transformation is valid).
    Handling of integer equality/non-equality checks on partially defined
    values is also improved on some architectures.

* exp-sgcheck:

  - The exprimental Stack and Global Array Checking tool has been removed.
    It only ever worked on x86 and amd64, and even on those it had a
    high false positive rate and was slow.  An alternative for detecting
    stack and global array overruns is using the AddressSanitizer (ASAN)
    facility of the GCC and Clang compilers, which require you to rebuild
    your code with -fsanitize=address.

* ==================== OTHER CHANGES ====================

* New and modified GDB server monitor features:

  - Option -T tells vgdb to output a timestamp in the vgdb information messages.

  - The gdbserver monitor commands that require an address and an optional
    length argument now accepts the alternate 'C like' syntax \ 
"address[length]".
    For example, the memcheck command "monitor who_points_at 0x12345678 \ 
120"
    can now also be given as "monitor who_points_at 0x12345678[120]".

Release 3.15.0 (12 April 2019)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.15.0 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.  There is also preliminary
support for X86/macOS 10.13 and AMD64/macOS 10.13.

* ==================== CORE CHANGES ===================

* The XTree Massif output format now makes use of the information obtained
  when specifying --read-inline-info=yes.

* amd64 (x86_64): the RDRAND and F16C insn set extensions are now supported.

* ==================== TOOL CHANGES ====================

* DHAT:

  - DHAT been thoroughly overhauled, improved, and given a GUI.  As a result,
    it has been promoted from an experimental tool to a regular tool.  Run it
    with --tool=dhat instead of --tool=exp-dhat.

  - DHAT now prints only minimal data when the program ends, instead writing
    the bulk of the profiling data to a file.  As a result, the --show-top-n
    and --sort-by options have been removed.

  - Profile results can be viewed with the new viewer, dh_view.html.  When
    a run ends, a short message is printed, explaining how to view the result.

  - See the documentation for more details.

* Cachegrind:

  - cg_annotate has a new option, --show-percs, which prints percentages next
    to all event counts.

* Callgrind:

  - callgrind_annotate has a new option, --show-percs, which prints percentages
    next to all event counts.

  - callgrind_annotate now inserts commas in call counts, and
    sort the caller/callee lists in the call tree.

* Massif:

  - The default value for --read-inline-info is now "yes" on
    Linux/Android/Solaris. It is still "no" on other OS.

* Memcheck:

  - The option --xtree-leak=yes (to output leak result in xtree format)
    automatically activates the option --show-leak-kinds=all, as xtree
    visualisation tools such as kcachegrind can in any case select what kind
    of leak to visualise.

  - There has been further work to avoid false positives.  In particular,
    integer equality on partially defined inputs (C == and !=) is now handled
    better.

* ==================== OTHER CHANGES ====================

* The new option --show-error-list=no|yes displays, at the end of the run, the
  list of detected errors and the used suppressions.  Prior to this change,
  showing this information could only be done by specifying "-v -v", \ 
but that
  also produced a lot of other possibly-non-useful messages.  The option -s is
  equivalent to --show-error-list=yes.

Release 3.14.0 (9 October 2018)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3.14.0 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.  There is also preliminary
support for X86/macOS 10.13, AMD64/macOS 10.13.

* ==================== CORE CHANGES ===================

* The new option --keep-debuginfo=no|yes (default no) can be used to retain
  debug info for unloaded code.  This allows saved stack traces (e.g. for
  memory leaks) to include file/line info for code that has been dlclose'd (or
  similar).  See the user manual for more information and known limitations.

* Ability to specify suppressions based on source file name and line number.

* Majorly overhauled register allocator.  No end-user changes, but the JIT
  generates code a bit more quickly now.

* ================== PLATFORM CHANGES =================

* Preliminary support for macOS 10.13 has been added.

* mips: support for MIPS32/MIPS64 Revision 6 has been added.

* mips: support for MIPS SIMD architecture (MSA) has been added.

* mips: support for MIPS N32 ABI has been added.

* s390: partial support for vector instructions (integer and string) has been
  added.

* ==================== TOOL CHANGES ====================

* Helgrind: Addition of a flag
  --delta-stacktrace=no|yes [yes on linux amd64/x86]
  which specifies how full history stack traces should be computed.
  Setting this to =yes can speed up Helgrind by 25% when using
  --history-level=full.

* Memcheck: reduced false positive rate for optimised code created by Clang 6
  / LLVM 6 on x86, amd64 and arm64.  In particular, Memcheck analyses code
  blocks more carefully to determine where it can avoid expensive definedness
  checks without loss of precision.  This is controlled by the flag
  --expensive-definedness-checks=no|auto|yes [auto].

* ==================== OTHER CHANGES ====================

* Valgrind is now buildable with link-time optimisation (LTO).  A new
  configure option --enable-lto=yes allows building Valgrind with LTO.  If the
  toolchain supports it, this produces a smaller/faster Valgrind (up to 10%).
  Note that if you are doing Valgrind development, --enable-lto=yes massively
  slows down the build process.
