[Valgrind-users] Valgrind-3.23.0 is available

[Mark W. <ma...@kl...>]

We are pleased to announce a new release of Valgrind, version 3.23.0,
available from https://valgrind.org/downloads/current.html.

See the release notes below for details of changes.

Our thanks to all those who contribute to Valgrind's development.  This
release represents a great deal of time, energy and effort on the part
of many people.

Happy and productive debugging and profiling,

-- The Valgrind Developers

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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, AMD64/MacOSX 10.12, X86/FreeBSD, AMD64/FreeBSD
and ARM64/FreeBSD  There is also preliminary support for X86/macOS 10.13,
AMD64/macOS 10.13 and nanoMIPS/Linux.

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

* --track-fds=yes will now also warn about double closing of file
  descriptors. Printing the context where the file descriptor was
  originally opened and where it was previously closed.

* --track-fds=yes also produces "real" errors now which can be
  suppressed and work with --error-exitcode. When combined with
  --xml the xml-output now also includes FdBadClose and FdNotClosed
  error kinds (see docs/internals/xml-output-protocol5.txt).

* The option --show-error-list=no|yes now accepts a new value all.
  This indicates to also print the suppressed errors.
  This is useful to analyse which errors are suppressed by which
  suppression entries.
  The valgrind monitor command 'v.info all_errors' similarly now
  accepts a new optional argument 'also_suppressed' to show
  all errors including the suppressed errors.

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

* Added ARM64 support for FreeBSD.

* ARM64 now supports dotprod instructions (sdot/udot).

* AMD64 better supports code build with -march=x86-64-v3.
  fused-multiple-add instructions (fma) are now emulated more
  accurately. And memcheck now handles __builtin_strcmp using 128/256
  bit vectors with sse4.1, avx/avx2.

* S390X added support for NNPA (neural network processing assist)
  facility vector instructions VCNF, VCLFNH, VCFN, VCLFNL, VCRNF and
  NNPA (z16/arch14).

* X86 recognizes new binutils-2.42 nop patterns.

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

* The none tool now also supports xml output.

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