63 Release 3.22.0 (31 Oct 2023)
64 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
66 This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
67 PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,
68 MIPS64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android,
69 X86/Solaris, AMD64/Solaris, AMD64/MacOSX 10.12, X86/FreeBSD and
70 AMD64/FreeBSD. There is also preliminary support for X86/macOS 10.13,
71 AMD64/macOS 10.13 and nanoMIPS/Linux.
73 * ==================== CORE CHANGES ===================
75 * A new configure option --with-gdbscripts-dir lets you install
76 the gdb valgrind python monitor scripts in a specific location.
77 For example a distro could use it to install the scripts in a
78 safe load location --with-gdbscripts-dir=%{_datadir}/gdb/auto-load
79 It is also possible to configure --without-gdb-scripts-dir so no
80 .debug_gdb_scripts section is added to the vgpreload library and
81 no valgrind-monitor python scripts are installed at all.
83 * ================== PLATFORM CHANGES =================
85 * Support has been added for FreeBSD 14 and FreeBSD 15.
86 * Add support for the folllowing FreeBSD system calls:
87 close_range, kqueuex, membarrier, timerfd_create,
88 timerfd_settime and timerfd_gettime (all added in FreeBSD 15).
90 * ==================== TOOL CHANGES ===================
92 * Memcheck now tests and warns about the values used for
93 alignment and size. These apply to various functions: memalign,
94 posix_memalign and aligned_alloc in C and various overloads
95 of operators new and delete in C++. The kinds of error that can
97 - invalid alignment, for instance the alignment is usually required
99 - mismatched alignment between aligned allocation and aligned
101 - mismatched size when sized delete is used
102 - bad size for functions that have implementation defined behaviour
103 when the requested size is zero
106 - You can now profile part of a program's execution using the new
107 `CACHEGRIND_START_INSTRUMENTATION` and `CACHEGRIND_STOP_INSTRUMENTATION`
108 client requests, along with the new `--instr-at-start` option. The
109 behaviour is the same as Callgrind's equivalent functionality.
111 * ==================== FIXED BUGS ====================
113 The following bugs have been fixed or resolved. Note that "n-i-bz"
114 stands for "not in bugzilla" -- that is, a bug that was reported to us
115 but never got a bugzilla entry. We encourage you to file bugs in
116 bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
117 than mailing the developers (or mailing lists) directly -- bugs that
118 are not entered into bugzilla tend to get forgotten about or ignored.

168 Release 3.21.0 (28 Apr 2023)
169 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
171 This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
172 PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,
173 MIPS64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android,
174 X86/Solaris, AMD64/Solaris, AMD64/MacOSX 10.12, X86/FreeBSD and
175 AMD64/FreeBSD. There is also preliminary support for X86/macOS 10.13,
176 AMD64/macOS 10.13 and nanoMIPS/Linux.
178 * ==================== CORE CHANGES ===================
180 * When GDB is used to debug a program running under valgrind using
181 the valgrind gdbserver, GDB will automatically load some
182 python code provided in valgrind defining GDB front end commands
183 corresponding to the valgrind monitor commands.
184 These GDB front end commands accept the same format as
185 the monitor commands directly sent to the Valgrind gdbserver.
186 These GDB front end commands provide a better integration
187 in the GDB command line interface, so as to use for example
188 GDB auto-completion, command specific help, searching for
189 a command or command help matching a regexp, ...
190 For relevant monitor commands, GDB will evaluate arguments
191 to make the use of monitor commands easier.
192 For example, instead of having to print the address of a variable
193 to pass it to a subsequent monitor command, the GDB front end
194 command will evaluate the address argument. It is for example
196 (gdb) memcheck who_points_at &some_struct sizeof(some_struct)
199 $2 = (some_struct_type *) 0x1130a0 <some_struct>
200 (gdb) p sizeof(some_struct)
202 (gdb) monitor who_point_at 0x1130a0 40
204 * The vgdb utility now supports extended-remote protocol when
205 invoked with --multi. In this mode the GDB run command is
206 supported. Which means you don't need to run gdb and valgrind
207 from different terminals. So for example to start your program
208 in gdb and run it under valgrind you can do:
210 (gdb) set remote exec-file prog
212 (gdb) target extended-remote | vgdb --multi
215 * The behaviour of realloc with a size of zero can now
216 be changed for tools that intercept malloc. Those
217 tools are memcheck, helgrind, drd, massif and dhat.
218 Realloc implementations generally do one of two things
219 - free the memory like free() and return NULL
220 (GNU libc and ptmalloc).
221 - either free the memory and then allocate a
222 minimum sized block or just return the
223 original pointer. Return NULL if the
224 allocation of the minimum sized block fails
225 (jemalloc, musl, snmalloc, Solaris, macOS).
226 When Valgrind is configured and built it will
227 try to match the OS and libc behaviour. However
228 if you are using a non-default library to replace
229 malloc and family (e.g., musl on a glibc Linux or
230 tcmalloc on FreeBSD) then you can use a command line
231 option to change the behaviour of Valgrind:
232 --realloc-zero-bytes-frees=yes|no [yes on Linux glibc, no otherwise]
234 * ================== PLATFORM CHANGES =================
236 * Make the address space limit on FreeBSD amd64 128Gbytes
237 (the same as Linux and Solaris, it was 32Gbytes)
239 * ==================== TOOL CHANGES ===================
242 - When doing a delta leak_search, it is now possible to only
243 output the new loss records compared to the previous leak search.
244 This is available in the memcheck monitor command 'leak_search'
245 by specifying the "new" keyword or in your program by using
246 the client request VALGRIND_DO_NEW_LEAK_CHECK.
247 Whenever a "delta" leak search is done (i.e. when specifying
248 "new" or "increased" or "changed" in the monitor command),
249 the new loss records have a "new" marker.
250 - Valgrind now contains python code that defines GDB memcheck
251 front end monitor commands. See CORE CHANGES.
252 - Performs checks for the use of realloc with a size of zero.
253 This is non-portable and a source of errors. If memcheck
254 detects such a usage it will generate an error
255 realloc() with size 0
256 followed by the usual callstacks.
257 A switch has been added to allow this to be turned off:
258 --show-realloc-size-zero=yes|no [yes]
261 - The option ---history-backtrace-size=<number> allows to configure
262 the number of entries to record in the stack traces of "old"
263 accesses. Previously, this number was hardcoded to 8.
264 - Valgrind now contains python code that defines GDB helgrind
265 front end monitor commands. See CORE CHANGES.
268 - `--cache-sim=no` is now the default. The cache simulation is old and
269 unlikely to match any real modern machine. This means only the `Ir`
270 event are gathered by default, but that is by far the most useful
272 - `cg_annotate`, `cg_diff`, and `cg_merge` have been rewritten in
273 Python. As a result, they all have more flexible command line
274 argument handling, e.g. supporting `--show-percs` and
275 `--no-show-percs` forms as well as the existing `--show-percs=yes`
276 and `--show-percs=no`.
277 - `cg_annotate` has some functional changes.
278 - It's much faster, e.g. 3-4x on common cases.
279 - It now supports diffing (with `--diff`, `--mod-filename`, and
280 `--mod-funcname`) and merging (by passing multiple data files).
281 - It now provides more information at the file and function level.
282 There are now "File:function" and "Function:file" sections. These
283 are very useful for programs that use inlining a lot.
284 - Support for user-annotated files and the `-I`/`--include` option
285 has been removed, because it was of little use and blocked other
287 - The `--auto` option is renamed `--annotate`, though the old
288 `--auto=yes`/`--auto=no` forms are still supported.
289 - `cg_diff` and `cg_merge` are now deprecated, because `cg_annotate`
290 now does a better job of diffing and merging.
291 - The Cachegrind output file format has changed very slightly, but in
292 ways nobody is likely to notice.
295 - Valgrind now contains python code that defines GDB callgrind
296 front end monitor commands. See CORE CHANGES.
299 - Valgrind now contains python code that defines GDB massif
300 front end monitor commands. See CORE CHANGES.
303 - A new kind of user request has been added which allows you to
304 override the 1024 byte limit on access count histograms for blocks
305 of memory. The client request is DHAT_HISTOGRAM_MEMORY.

439 AMD64/macOS 10.13 and nanoMIPS/Linux.
441 * ==================== CORE CHANGES ===================
443 * Fix Rust v0 name demangling.
444 * The Linux rseq syscall is now implemented as (silently) returning ENOSYS.
445 * Add FreeBSD syscall wrappers for __specialfd and __realpathat.
446 * Remove FreeBSD dependencies on COMPAT10, which fixes compatibility with HardenedBSD
448 * ================== PLATFORM CHANGES =================
451 - ignore the "v8.x" architecture levels, only look at actual CPU features
452 present. Fixes mismatch detected between RDMA and atomics features
453 preventing startup on some QEMU configurations.
454 - Implement LD{,A}XP and ST{,L}XP
455 - Fix incorrect code emitted for doubleword CAS.
458 - Fix sys_ipc semtimedop syscall
459 - Fix VFLRX and WFLRX instructions
460 - Fix EXRL instruction with negative offset
463 - Reimplement the vbpermq instruction support to generate less Iops and
464 avoid overflowing internal buffers.
465 - Fix checking for scv support to avoid "Facility 'SCV' unavailable (12),
466 exception" messages in dmsg.
467 - Fix setting condition code for Vector Compare quad word instructions.
468 - Fix fix lxsibzx, lxsihzx and lxsihzx instructions so they only load
469 their respective sized data.
470 - Fix the prefixed stq instruction in PC relative mode.
472 * ==================== TOOL CHANGES ===================
475 - Speed up --track-origins=yes for large (in the range of hundreds to
476 thousands of megabytes) mmap/munmaps.
478 - Several fixes for new versions of libstd++ using new posix try_lock
481 * ==================== FIXED BUGS ====================
483 The following bugs have been fixed or resolved. Note that "n-i-bz"
484 stands for "not in bugzilla" -- that is, a bug that was reported to us
485 but never got a bugzilla entry. We encourage you to file bugs in
486 bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
487 than mailing the developers (or mailing lists) directly -- bugs that
488 are not entered into bugzilla tend to get forgotten about or ignored.
