2017-06-21Upgrade to valgrind 3.13.0 (15 June 2017).Elliott Hughes
Release 3.13.0 (15 June 2017) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3.13.0 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. * ==================== CORE CHANGES =================== * The translation cache size has been increased to keep up with the demands of large applications. The maximum number of sectors has increased from 24 to 48. The default number of sectors has increased from 16 to 32 on all targets except Android, where the increase is from 6 to 12. * The amount of memory that Valgrind can use has been increased from 64GB to 128GB. In particular this means your application can allocate up to about 60GB when running on Memcheck. * Valgrind's default load address has been changed from 0x3800'0000 to 0x5800'0000, so as to make it possible to load larger executables. This should make it possible to load executables of size at least 1200MB. * A massive spaceleak caused by reading compressed debuginfo files has been fixed. Valgrind should now be entirely usable with gcc-7.0 "-gz" created debuginfo. * The C++ demangler has been updated. * Support for demangling Rust symbols has been added. * A new representation of stack traces, the "XTree", has been added. An XTree is a tree of stacktraces with data associated with the stacktraces. This is used by various tools (Memcheck, Helgrind, Massif) to report on the heap consumption of your program. Reporting is controlled by the new options --xtree-memory=none|allocs|full and --xtree-memory-file=<file>. A report can also be produced on demand using the gdbserver monitor command 'xtmemory [<filename>]>'. The XTree can be output in 2 formats: 'callgrind format' and 'massif format. The existing visualisers for these formats (e.g. callgrind_annotate, KCachegrind, ms_print) can be used to visualise and analyse these reports. Memcheck can also produce XTree leak reports using the Callgrind file format. For more details, see the user manual. * ================== PLATFORM CHANGES ================= * ppc64: support for ISA 3.0B and various fixes for existing 3.0 support * amd64: fixes for JIT failure problems on long AVX2 code blocks * amd64 and x86: support for CET prefixes has been added * arm32: a few missing ARMv8 instructions have been implemented * arm64, mips64, mips32: an alternative implementation of Load-Linked and Store-Conditional instructions has been added. This is to deal with processor implementations that implement the LL/SC specifications strictly and as a result cause Valgrind to hang in certain situations. The alternative implementation is automatically enabled at startup, as required. You can use the option --sim-hints=fallback-llsc to force-enable it if you want. * Support for OSX 10.12 has been improved. * On Linux, clone handling has been improved to honour CLONE_VFORK that involves a child stack. Note however that CLONE_VFORK | CLONE_VM is handled like CLONE_VFORK (by removing CLONE_VM), so applications that depend on CLONE_VM exact semantics will (still) not work. * The TileGX/Linux port has been removed because it appears to be both unused and unsupported. * ==================== TOOL CHANGES ==================== * Memcheck: - Memcheck should give fewer false positives when running optimised Clang/LLVM generated code. - Support for --xtree-memory and 'xtmemory [<filename>]>'. - New command line options --xtree-leak=no|yes and --xtree-leak-file=<file> to produce the end of execution leak report in a xtree callgrind format file. - New option 'xtleak' in the memcheck leak_check monitor command, to produce the leak report in an xtree file. * Massif: - Support for --xtree-memory and 'xtmemory [<filename>]>'. - For some workloads (typically, for big applications), Massif memory consumption and CPU consumption has decreased significantly. * Helgrind: - Support for --xtree-memory and 'xtmemory [<filename>]>'. - addition of client request VALGRIND_HG_GNAT_DEPENDENT_MASTER_JOIN, useful for Ada gnat compiled applications. * ==================== OTHER CHANGES ==================== * For Valgrind developers: in an outer/inner setup, the outer Valgrind will append the inner guest stacktrace to the inner host stacktrace. This helps to investigate the errors reported by the outer, when they are caused by the inner guest program (such as an inner regtest). See README_DEVELOPERS for more info. * To allow fast detection of callgrind files by desktop environments and file managers, the format was extended to have an optional first line that uniquely identifies the format ("# callgrind format"). Callgrind creates this line now, as does the new xtree functionality. * File name template arguments (such as --log-file, --xtree-memory-file, ...) have a new %n format letter that is replaced by a sequence number. * "--version -v" now shows the SVN revision numbers from which Valgrind was built. * ==================== 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.

2017-04-19Upgrade to valgrind 3.12.0.Elliott Hughes
Release 3.12.0 (20 October 2016) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3.12.0 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, X86/MacOSX 10.10 and AMD64/MacOSX 10.10. There is also preliminary support for X86/MacOSX 10.11/12, AMD64/MacOSX 10.11/12 and TILEGX/Linux. * ================== PLATFORM CHANGES ================= * POWER: Support for ISA 3.0 has been added * mips: support for O32 FPXX ABI has been added. * mips: improved recognition of different processors * mips: determination of page size now done at run time * amd64: Partial support for AMD FMA4 instructions. * arm, arm64: Support for v8 crypto and CRC instructions. * Improvements and robustification of the Solaris port. * Preliminary support for MacOS 10.12 (Sierra) has been added. Whilst 3.12.0 continues to support the 32-bit x86 instruction set, we would prefer users to migrate to 64-bit x86 (a.k.a amd64 or x86_64) where possible. Valgrind's support for 32-bit x86 has stagnated in recent years and has fallen far behind that for 64-bit x86 instructions. By contrast 64-bit x86 is well supported, up to and including AVX2. * ==================== TOOL CHANGES ==================== * Memcheck: - Added meta mempool support for describing a custom allocator which: - Auto-frees all chunks assuming that destroying a pool destroys all objects in the pool - Uses itself to allocate other memory blocks - New flag --ignore-range-below-sp to ignore memory accesses below the stack pointer, if you really have to. The related flag --workaround-gcc296-bugs=yes is now deprecated. Use --ignore-range-below-sp=1024-1 as a replacement. * DRD: - Improved thread startup time significantly on non-Linux platforms. * DHAT - Added collection of the metric "tot-blocks-allocd" * ==================== OTHER CHANGES ==================== * Replacement/wrapping of malloc/new related functions is now done not just for system libraries by default, but for any globally defined malloc/new related function (both in shared libraries and statically linked alternative malloc implementations). The dynamic (runtime) linker is excluded, though. To only intercept malloc/new related functions in system libraries use --soname-synonyms=somalloc=nouserintercepts (where "nouserintercepts" can be any non-existing library name). This new functionality is not implemented for MacOS X. * The maximum number of callers in a suppression entry is now equal to the maximum size for --num-callers (500). Note that --gen-suppressions=yes|all similarly generates suppressions containing up to --num-callers frames. * New and modified GDB server monitor features: - Valgrind's gdbserver now accepts the command 'catch syscall'. Note that you must have GDB >= 7.11 to use 'catch syscall' with gdbserver. * New option --run-cxx-freeres=<yes|no> can be used to change whether __gnu_cxx::__freeres() cleanup function is called or not. Default is 'yes'. * Valgrind is able to read compressed debuginfo sections in two formats: - zlib ELF gABI format with SHF_COMPRESSED flag (gcc option -gz=zlib) - zlib GNU format with .zdebug sections (gcc option -gz=zlib-gnu) * Modest JIT-cost improvements: the cost of instrumenting code blocks for the most common use case (x86_64-linux, Memcheck) has been reduced by 10%-15%. * Improved performance for programs that do a lot of discarding of instruction address ranges of 8KB or less. * The C++ symbol demangler has been updated. * More robustness against invalid syscall parameters on Linux. * ==================== 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.
