We are pleased to announce a new release of Valgrind, version 3.14.0, available from http://www.valgrind.org.
3.14.0 updates support for existing platforms. 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 3.14.0 (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. * ==================== 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. To see details of a given bug, visit https://bugs.kde.org/show_bug.cgi?id=XXXXXX where XXXXXX is the bug number as listed below. 79362 Debug info is lost for .so files when they are dlclose'd 208052
