valgrind-3.15.0

[Douglas R. Reno]

New minor version

[Bruce Dubbs]

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.
