We are pleased to announce a new release of Valgrind, version 3.18.1,
available from http://valgrind.org/downloads/current.html.
3.18.1 fixes a number of bugs and adds support for glibc-2.34, and for new
platforms x86/FreeBSD and amd64/FreeBSD. Debuginfo reading is faster, and
Rust demangling has been improved. For PPC64, ISA 3.1 support has been
completed, and some newer ARM64 and S390 instructions are also supported. See
the release notes below for details of changes. Note, 3.18.0 had no formal
release -- it was pulled at the last minute due to a packaging problem.
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
Release 3.18.0 (15 Oct 2021)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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 and
AMD64/FreeBSD. There is also preliminary support for X86/macOS 10.13,
AMD64/macOS 10.13 and nanoMIPS/Linux.
* ==================== CORE CHANGES ===================
* The libiberty demangler has been updated, which brings support for
Rust v0 name demangling
* __libc_freeres isn't called anymore after the program recieves a
fatal signal. Causing some internal glibc resources to hang around,
but preventing any crashes after the program has ended.
* The DWARF reader is now very much faster at startup when just
--read-inline-info=yes (the default in most cases) is given.
* glibc 2.34, which moved various functions from libpthread.so into
libc.so, is now supported.
* ================== PLATFORM CHANGES =================
* arm64:
- v8.2 scalar and vector FABD, FACGE, FACGT and FADD.
- v8.2 FP compare & conditional compare instructions.
- Zero variants of v8.2 FP compare instructions.
* s390:
- Support the miscellaneous-instruction-extensions facility 3 and
the vector-enhancements facility 2. This enables programs
compiled with "-march=arch13" or "-march=z15" to be executed
under Valgrind.
* ppc64:
- ISA 3.1 support is now complete
- ISA 3.0 support for the darn instruction added.
- ISA 3.0 support for the vector system call instruction scv added.
- ISA 3.0 support for the copy, paste and cpabort instructions added.
* Support for X86/FreeBSD and AMD64/FreeBSD has been added.
* ==================== OTHER CHANGES ====================
* Memcheck on amd64: minor fixes to remove some false positive
undef-value errors
* ==================== 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.
