We are pleased to announce a new release of Valgrind, version 3.15.0,
available from http://valgrind.org/downloads/current.html. The source tarball
is signed with the PGP key at the bottom of this message.
3.15.0 updates support for existing platforms and adds a major overhaul of the
DHAT heap profiler. There are, as ever, many refinements and bug fixes. The
release notes below give more details.
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.
Unfortunately the Solaris port no longer has a maintainer. If you have some
familiarity with low level Solaris system programming and would like to help
out, please get in touch. We are also looking for further assistance with the
MacOS port.
Happy and productive debugging and profiling,
-- The Valgrind Developers
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.
* ==================== 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.
